The ForgeRock Common REST API works across the platform to provide common ways to access web resources and collections of resources.

Schedule tasks and events

The scheduler service lets you schedule reconciliation and synchronization tasks, trigger scripts, collect and run reports, trigger workflows, and perform custom logging.

The service depends on the Quartz Scheduler (bundled with IDM), and supports Quartz simple triggers and cron triggers. Use the trigger type that suits your scheduling requirements. For more information, refer to the Quartz documentation on SimpleTriggers and CronTriggers.

By default, IDM picks up changes to scheduled tasks and events dynamically, during initialization and also at runtime. For more information, refer to Configuration changes.

In addition to the fine-grained scheduling facility, you can perform a scheduled batch scan for a specified date in IDM data, and then automatically run a task when this date is reached. For more information, refer to Scan data to trigger tasks.

Configure the scheduler service

There is a distinction between the configuration of the scheduler service, and the configuration of individual scheduled tasks and events. The scheduler configuration has the following format, and configures the Quartz Scheduler:

{
    "threadPool" : {
        "threadCount" : 10
    },
    "scheduler" : {
        "executePersistentSchedules" : {
            "$bool" : "&{openidm.scheduler.execute.persistent.schedules}"
        }
    }
}
  • threadCount specifies the maximum number of threads that are available for running scheduled tasks concurrently.

  • executePersistentSchedules lets you disable persistent schedules for a specific node. If this parameter is set to false, the Scheduler Service will support the management of persistent schedules (CRUD operations) but it will not run any persistent schedules. The value of this property can be a string or boolean. Its default value (set in resolver/boot.properties ) is true.

  • advancedProperties (optional) lets you configure additional properties for the Quartz Scheduler.

For details of all the configurable properties for the Quartz Scheduler, refer to the Quartz Scheduler Configuration Reference.

Configure schedules

You can schedule tasks and events using:

By convention, IDM uses file names of the form schedule-schedule-name.json, where schedule-name is a logical name for the scheduled operation; for example, schedule-reconcile_systemCsvAccounts_managedUser.json. There are several example schedule configuration files in the openidm/samples/example-configurations/schedules directory.

Each schedule configuration has the following format:

{
 "enabled"             : boolean,
 "persisted"           : boolean,
 "recoverable"         : boolean,
 "concurrentExecution" : boolean,
 "type"                : "simple | cron",
 "repeatInterval"      : (optional) integer,
 "repeatCount"         : (optional) integer,
 "startTime"           : "(optional) time",
 "endTime"             : "(optional) time",
 "schedule"            : "cron expression",
 "misfirePolicy"       : "optional, string",
 "invokeService"       : "service identifier",
 "invokeContext"       : "service specific context info",
 "invokeLogLevel"      : "(optional) level"
}

Schedule configuration properties

The schedule configuration properties are defined as follows:

enabled

Set to true to enable the schedule. When this property is false, IDM considers the schedule configuration dormant, and does not allow it to be triggered or launched.

If you want to retain a schedule configuration, but do not want it used, set enabled to false for task and event schedulers, instead of changing the configuration or cron expressions.

persisted (optional)

Specifies whether the schedule state should be persisted or stored only in RAM. Boolean (true or false), false by default.

In a clustered environment, this property must be set to true to have the schedule fire only once across the cluster. For more information, refer to Configure Persistent Schedules.

If the schedule is stored only in RAM, the schedule will be lost when IDM is restarted.
recoverable (optional)

Specifies whether jobs that have failed mid-execution (as a result of a JVM crash or otherwise unexpected termination) should be recovered. Boolean (true or false), false by default.

concurrentExecution

Specifies whether multiple instances of the same schedule can run concurrently. Boolean (true or false), false by default. Multiple instances of the same schedule cannot run concurrently by default. This setting prevents a new scheduled task from being launched before the same previously launched task has completed. For example, under normal circumstances you would want a liveSync operation to complete before the same operation was launched again. To enable multiple schedules to run concurrently, set this parameter to true. The behavior of missed scheduled tasks is governed by the misfire policy.

type

The trigger type, either simple or cron.

To decide which trigger type to use, refer to the Quartz documentation on SimpleTriggers and CronTriggers.

repeatCount

Used only for simple triggers ("type" : "simple").

The number of times the schedule must be repeated. The repeat count can be zero, a positive integer, or -1. A value of -1 indicates that the schedule should repeat indefinitely.

If you do not specify a repeat count, the value defaults to -1.

repeatInterval

Used only for simple triggers ("type" : "simple").

Specifies the interval, in milliseconds, between trigger firings. The repeat interval must be zero or a positive long value. If you set the repeat interval to zero, the scheduler will trigger repeatCount firings concurrently (or as close to concurrently as possible).

If you do not specify a repeat interval, the value defaults to 0.

startTime (optional)

This parameter starts the schedule at some time in the future. If the parameter is omitted, empty, or set to a time in the past, the task or event is scheduled to start immediately.

Use ISO 8601 format to specify times and dates (yyyy-MM-dd’T’HH:mm:ss).

To specify a time zone, include the time zone at the end of the startTime, in the format +|-hh:mm; for example 2017-10-31T15:53:00+05:00. If you specify both a startTime and an endTime, they must have the same time zone.

endTime (optional)

Specifies when the schedule must end, in ISO 8601 format (yyyy-MM-dd’T’HH:mm:ss+|-hh:mm).

schedule

Used only for cron triggers ("type" : "cron").

Takes cron expression syntax. For more information, refer to the CronTrigger Tutorial and Lesson 6: CronTrigger.

misfirePolicy

For persistent schedules, this optional parameter specifies the behavior if the scheduled task is missed, for some reason. Possible values are as follows:

  • fireAndProceed. The first run of a missed schedule is immediately launched when the server is back online. Subsequent runs are discarded. After this, the normal schedule is resumed.

  • doNothing. All missed schedules are discarded and the normal schedule is resumed when the server is back online.

invokeService

Defines the type of scheduled event or action. The value of this parameter can be one of the following:

  • sync for reconciliation.

  • provisioner for liveSync.

  • script to call some other scheduled operation defined in a script.

  • taskScanner to define a scheduled task that queries a set of objects. For more information, refer to Scan data to trigger tasks.

invokeContext

Specifies contextual information, depending on the type of scheduled event (the value of the invokeService parameter).

The following example invokes reconciliation:

{
    "invokeService": "sync",
    "invokeContext": {
        "action": "reconcile",
        "mapping": "systemLdapAccount_managedUser"
    }
}

The following example invokes a liveSync operation:

{
    "invokeService": "provisioner",
    "invokeContext": {
        "action": "liveSync",
        "source": "system/ldap/__ACCOUNT__"
    }
}

For scheduled liveSync tasks, the source property follows IDM’s convention for a pointer to an external resource object and takes the form system/resource-name/object-type.

The following example invokes a script, which prints the node ID performing the scheduled job and the time to the console.

A similar sample schedule is provided in schedule-script.json in the /path/to/openidm/samples/example-configurations/schedules directory.

{
    "enabled" : true,
    "type": "simple",
    "repeatInterval": 3600000,
    "persisted" : true,
    "concurrentExecution" : false,
    "invokeService": "script",
    "invokeContext": {
        "script" : {
            "type" : "text/javascript",
            "source" : "java.lang.System.out.println('Job executing on ' + identityServer.getProperty('openidm.node.id') + ' at: ' + java.lang.System.currentTimeMillis());"
        }
    }
}

These are sample configurations only. Your schedule configuration will differ according to your specific requirements.

invokeLogLevel (optional)

Specifies the level at which the invocation will be logged. Particularly for schedules that run very frequently, such as liveSync, the scheduled task can generate significant output to the log file, and you should adjust the log level accordingly. The default schedule log level is info. The value can be set to any one of the SLF4J log levels:

  • trace

  • debug

  • info

  • warn

  • error

  • fatal

Manage schedules using REST

The scheduler service is exposed under the /openidm/scheduler context path. Within this context path, the defined scheduled jobs are accessible at /openidm/scheduler/job. A job is the actual task that is run. Each job contains a trigger that starts the job. The trigger defines the schedule according to which the job is executed. You can read and query the existing triggers on the /openidm/scheduler/trigger context path.

The following examples show how schedules are validated, created, read, queried, updated, and deleted, over REST, by using the scheduler service.

When you configure schedules over REST, changes made to the schedules are not pushed back into the configuration service. Managing schedules by using the /openidm/scheduler/job context path essentially bypasses the configuration service and sends the request directly to the scheduler.

If you need to perform an operation on a schedule that was created by using the configuration service (by placing a schedule file in the conf/ directory), you must direct your request to the /openidm/config context path, and not to the /openidm/scheduler/job context path.

PATCH operations are not supported on the scheduler context path. To patch a schedule, use the config context path.

Validate cron trigger expressions

Schedules are defined using Quartz cron or simple triggers. If you use a cron trigger, you can validate your cron expression by sending the expression as a JSON object to the scheduler context path:

curl \
--header "X-OpenIDM-Username: openidm-admin" \
--header "X-OpenIDM-Password: openidm-admin" \
--header "Content-Type: application/json" \
--header "Accept-API-Version: resource=2.0" \
--request POST \
--data '{
    "cronExpression": "0 0/1 * * * ?"
}' \
"http://localhost:8080/openidm/scheduler/job?_action=validateQuartzCronExpression"
{
  "valid": true
}

Define a schedule

To define a new schedule, send a PUT or POST request to the scheduler/job context path with the details of the schedule in the JSON payload. A PUT request lets you specify the ID of the schedule. A POST request assigns an ID automatically.

The following example uses a PUT request to create a schedule that fires a script (script/testlog.js) every second. The example assumes that the script exists in the specified location. The schedule configuration is as described in Configure Schedules:

curl \
--header "X-OpenIDM-Username: openidm-admin" \
--header "X-OpenIDM-Password: openidm-admin" \
--header "Content-Type: application/json" \
--header "Accept-API-Version: resource=2.0" \
--request PUT \
--data '{

}

Query scheduled jobs

You can query defined and running scheduled jobs using a regular query filter.

The following query returns the IDs of all defined schedules:

curl \
--header "X-OpenIDM-Username: openidm-admin" \
--header "X-OpenIDM-Password: openidm-admin" \
--header "Accept-API-Version: resource=2.0" \
--request GET \
"http://localhost:8080/openidm/scheduler/job?_queryFilter=true&_fields=_id"
{
  "result": [
    {
      "_id": "reconcile_systemLdapAccounts_managedUser"
    },
    {
      "_id": "testlog-schedule"
    }
  ]
  ...
}

The following query returns the IDs, enabled status, and next run date of all defined schedules:

curl \
--header "X-OpenIDM-Username: openidm-admin" \
--header "X-OpenIDM-Password: openidm-admin" \
--header "Accept-API-Version: resource=2.0" \
--request GET \
"http://localhost:8080/openidm/scheduler/job?_queryFilter=true&_fields=_id,enabled,nextRunDate"
{
  "result": [
    {
      "_id": "reconcile_systemLdapAccounts_managedUser",
      "enabled": false,
      "nextRunDate": null
    },
    {
      "_id": "testlog-schedule",
      "enabled": true,
      "nextRunDate": "2019-10-09T09:43:17.000Z"
    }
  ]
  ...
}

Update a schedule

To update a schedule definition, use a PUT request and update all the static properties of the object.

This example disables the testlog schedule created in the previous example by setting "enabled":false:

curl \
--header "X-OpenIDM-Username: openidm-admin" \
--header "X-OpenIDM-Password: openidm-admin" \
--header "Content-Type: application/json" \
--header "Accept-API-Version: resource=2.0" \
--request PUT \
--data '{
    "enabled": false,
    "type": "cron",
    "schedule": "0/1 * * * * ?",
    "persisted": true,
    "misfirePolicy": "fireAndProceed",
    "invokeService": "script",
    "invokeContext": {
        "script": {
            "type": "text/javascript",
            "file": "script/testlog.js"
        }
    }
}' \
"http://localhost:8080/openidm/scheduler/job/testlog-schedule"
{
  "_id": "testlog-schedule",
  "enabled": false,
  "persisted": true,
  "recoverable": false,
  "misfirePolicy": "fireAndProceed",
  "schedule": "0/1 * * * * ?",
  "repeatInterval": 0,
  "repeatCount": 0,
  "type": "cron",
  "invokeService": "org.forgerock.openidm.script",
  "invokeContext": {
    "script": {
      "type": "text/javascript",
      "file": "script/testlog.js"
    }
  },
  "invokeLogLevel": "info",
  "startTime": null,
  "endTime": null,
  "concurrentExecution": false,
  "triggers": [],
  "previousRunDate": null,
  "nextRunDate": null
}

When you disable a schedule, all triggers are removed, and the nextRunDate is set to null. If you re-enable the schedule, a new trigger is generated, and the nextRunDate is recalculated.

List running scheduled jobs

This example returns a list of the jobs that are currently executing. The list lets you decide whether to wait for a specific job to complete before shutting down a server.

  • This action does not list the jobs across a cluster, only the jobs currently executing on the node to which the request is routed.

  • The list is accurate only at the moment the request was issued, and can change at any time after the response is received.

curl \
--header "X-OpenIDM-Username: openidm-admin" \
--header "X-OpenIDM-Password: openidm-admin" \
--header "Accept-API-Version: resource=2.0" \
--request POST \
"http://localhost:8080/openidm/scheduler/job?_action=listCurrentlyExecutingJobs"
[
  {
    "enabled": true,
    "persisted": true,
    "misfirePolicy": "fireAndProceed",
    "type": "simple",
    "repeatInterval": 3600000,
    "repeatCount": -1,
    "invokeService": "org.forgerock.openidm.sync",
    "invokeContext": {
      "action": "reconcile",
      "mapping": "systemLdapAccounts_managedUser"
    },
    "invokeLogLevel": "info",
    "timeZone": null,
    "startTime": null,
    "endTime": null,
    "concurrentExecution": false
  }
]

Trigger a schedule manually

For testing purposes, and for certain administrative tasks, you can trigger a scheduled task manually, outside of its specified schedule. A scheduled task must be enabled before it can be triggered.

This command triggers the testlog-schedule job created previously:

curl \
--header "X-OpenIDM-Username: openidm-admin" \
--header "X-OpenIDM-Password: openidm-admin" \
--header "Accept-API-Version: resource=2.0" \
--request POST \
"http://localhost:8080/openidm/scheduler/job/testlog-schedule?_action=trigger"
{
  "success": true
}

This action is available only from version 2.0 of the scheduler API onwards.

Pause and resume a scheduled job

Instead of deleting and recreating scheduled jobs, you can pause and resume them if necessary. This command pauses the testlog-schedule job:

curl \
--header "X-OpenIDM-Username: openidm-admin" \
--header "X-OpenIDM-Password: openidm-admin" \
--header "Accept-API-Version: resource=2.0" \
--request POST \
"http://localhost:8080/openidm/scheduler/job/testlog-schedule?_action=pause"
{
  "success": true
}

This command resumes the testlog-schedule job:

curl \
--header "X-OpenIDM-Username: openidm-admin" \
--header "X-OpenIDM-Password: openidm-admin" \
--header "Accept-API-Version: resource=2.0" \
--request POST \
"http://localhost:8080/openidm/scheduler/job/testlog-schedule?_action=resume"
{
  "success": true
}

These actions are available only from version 2.0 of the scheduler API onwards.

Pause all scheduled jobs

You can temporarily suspend all scheduled jobs. This action does not cancel or interrupt jobs that are already in progress; it simply prevents any scheduled jobs from being invoked during the suspension period.

This command suspends all scheduled tasks and returns true if the tasks could be suspended successfully:

curl \
--header "X-OpenIDM-Username: openidm-admin" \
--header "X-OpenIDM-Password: openidm-admin" \
--header "Accept-API-Version: resource=2.0" \
--request POST \
"http://localhost:8080/openidm/scheduler/job?_action=pauseJobs"
{
  "success": true
}

Resume all scheduled jobs

You can resume scheduled jobs to start them up again. Any jobs that were missed during the downtime follow their configured misfirePolicy.

This command resumes all scheduled jobs and returns true if the jobs could be resumed successfully:

curl \
--header "X-OpenIDM-Username: openidm-admin" \
--header "X-OpenIDM-Password: openidm-admin" \
--header "Accept-API-Version: resource=2.0" \
--request POST \
"http://localhost:8080/openidm/scheduler/job?_action=resumeJobs"
{
  "success": true
}

Query schedule triggers

When a scheduled job is created, a trigger for that job is created automatically and is included in the schedule definition. The trigger is essentially what causes the job to be started. You can read all the triggers that have been generated on a system with the following query on the openidm/scheduler/trigger context path:

curl \
--header "X-OpenIDM-Username: openidm-admin" \
--header "X-OpenIDM-Password: openidm-admin" \
--header "Accept-API-Version: resource=2.0" \
--request GET \
"http://localhost:8080/openidm/scheduler/trigger?_queryFilter=true"
{
  "result": [
    {
      "_id": "scheduler-service-group.trigger-testlog-schedule",
      "_rev": "00000000db3523f1",
      "calendar": null,
      "group": "scheduler-service-group",
      "jobKey": "scheduler-service-group.testlog-schedule",
      "name": "trigger-testlog-schedule",
      "nodeId": "node1",
      "previousState": null,
      "serialized": {
      ...
      },
      "state": "NORMAL"
    }
  ]
}

The trigger object contents are:

_id

The ID of the trigger, which is based on the schedule ID. The trigger ID is made up of the group name, followed by trigger- prepended to the schedule ID: group.trigger-schedule-id. For example, if the schedule ID was testlog-schedule, then the trigger ID would be scheduler-service-group.trigger-testlog-schedule.

_rev

The revision of the trigger object. This property is reserved for internal use and specifies the revision of the object in the repository. This is the same value that is exposed as the object’s ETag through the REST API. The content of this property is not defined. No consumer should make any assumptions of its content beyond equivalence comparison.

previousState

The previous state of the trigger, before its current state. For a description of Quartz trigger states, refer to the Quartz API documentation.

name

The trigger name, which matches the ID of the schedule that created the trigger, with trigger- added: trigger-schedule-id.

state

The current state of the trigger. For a description of Quartz trigger states, refer to the Quartz API documentation.

nodeId

The ID of the node that has acquired the trigger, useful in a clustered deployment. If the trigger has not been acquired by a node yet, this will return null.

calendar

This is a part of the Quartz implementation, but is not currently supported by IDM. This will always return null.

serialized

The JSON serialization of the trigger class.

group

The name of the group that the trigger is in, always scheduler-service-group.

jobKey

The name of the job associated with the trigger: group.schedule-id.

To read the contents of a specific trigger, send a GET request to the trigger ID; for example:

curl \
--header "X-OpenIDM-Username: openidm-admin" \
--header "X-OpenIDM-Password: openidm-admin" \
--header "Accept-API-Version: resource=2.0" \
--request GET \
"http://localhost:8080/openidm/scheduler/trigger/scheduler-service-group.trigger-testlog-schedule"
{
  "_id": "scheduler-service-group.trigger-testlog-schedule",
  "_rev": "00000000cd1723dd",
  "calendar": null,
  "group": "scheduler-service-group",
  "jobKey": "scheduler-service-group.testlog-schedule",
  "name": "trigger-testlog-schedule",
  "nodeId": "node1",
  "previousState": null,
  "serialized": {
  ...
  },
  "state": "NORMAL"
}

To view the triggers that have been acquired, send a GET request to the scheduler, with a _queryFilter of nodeId. For example:

curl \
--header "X-OpenIDM-Username: openidm-admin" \
--header "X-OpenIDM-Password: openidm-admin" \
--header "Accept-API-Version: resource=2.0" \
--request GET \
"http://localhost:8080/openidm/scheduler/trigger?_queryFilter=(nodeId+pr)"

To view the triggers that have not yet been acquired by any node, send a GET request to the scheduler, with a _queryFilter to list the triggers with a null nodeId. For example:

curl \
--header "X-OpenIDM-Username: openidm-admin" \
--header "X-OpenIDM-Password: openidm-admin" \
--header "Accept-API-Version: resource=2.0" \
--request GET \
"http://localhost:8080/openidm/scheduler/trigger?_queryFilter=%21(nodeId+pr)"

Delete a schedule

To delete a schedule, send a DELETE request to the schedule ID. For example:

curl \
--header "X-OpenIDM-Username: openidm-admin" \
--header "X-OpenIDM-Password: openidm-admin" \
--header "Accept-API-Version: resource=2.0" \
--request DELETE \
"http://localhost:8080/openidm/scheduler/job/testlog-schedule"
{
  "_id": "testlog-schedule",
  "enabled": false,
  "persisted": true,
  "recoverable": false,
  "misfirePolicy": "fireAndProceed",
  "schedule": "0/1 * * * * ?",
  "repeatInterval": 0,
  "repeatCount": 0,
  "type": "cron",
  "invokeService": "org.forgerock.openidm.script",
  "invokeContext": {
    "script": {
      "type": "text/javascript",
      "file": "script/testlog.js"
    }
  },
  "invokeLogLevel": "info",
  "startTime": null,
  "endTime": null,
  "concurrentExecution": false,
  "triggers": [],
  "previousRunDate": null,
  "nextRunDate": null
}

The DELETE request returns the entire JSON object.

Manage schedules using the admin UI

To manage schedules using the admin UI, click Configure > Schedules.

Add, remove, and change schedules here. By default, only persisted schedules are shown in the Schedules list. To show non-persisted (in memory) schedules, select Filter by Type > In Memory.

Schedules and daylight savings time

The scheduler service supports Quartz cron triggers and simple triggers. Cron triggers schedule jobs to fire at specific times with respect to a calendar (rather than every N milliseconds). This scheduling can cause issues when clocks change for daylight savings time (DST) if the trigger time falls around the clock change time in your specific time zone.

Depending on the trigger schedule, and on the daylight event, the trigger might be skipped or might appear not to fire for a short period. This interruption can be particularly problematic for liveSync where schedules execute continuously. In this case, the time change (for example, from 02:00 back to 01:00) causes an hour break between each liveSync execution.

To prevent DST from having an impact on your schedules, use simple triggers instead of cron triggers.

Persistent schedules

By default, scheduling information (such as schedule state, and the details of the schedule run) is stored in RAM. This means that such information is lost when the server is rebooted. The schedule configuration is not lost when the server is shut down, and normal scheduling continues when the server is restarted. However, there are no details of missed schedule runs that should have occurred during the period the server was unavailable.

You can configure schedules to be persistent, which means that the scheduling information is stored in the internal repository, rather than in RAM. With persistent schedules, scheduling information is retained when the server is shut down. Any previously scheduled jobs can be rescheduled automatically when the server is restarted.

Persistent schedules also let you manage scheduling across a cluster (multiple IDM instances). When scheduling is persistent, a particular schedule will be launched only once across the cluster, rather than once on every instance. For example, if your deployment includes a cluster of nodes for high availability, you can use persistent scheduling to start a reconciliation operation on only one node in the cluster, instead of starting several competing reconciliation operations on each node.

Persistent schedules rely on timestamps. In a deployment where IDM instances run on separate machines, you must synchronize the system clocks of these machines using a time synchronization service that runs regularly. The clocks of all machines involved in persistent scheduling must be within one second of each other. For information on how you can achieve this using the Network Time Protocol (NTP) daemon, refer to the NTP RFC.

To configure persistent schedules, set persisted to true in the schedule configuration.

If the server is down when a scheduled task was set to occur, one or more runs of that schedule might be missed. To specify what action should be taken if schedules are missed, set the misfirePolicy in the schedule configuration file. The misfirePolicy determines what IDM should do if scheduled tasks are missed. Possible values are as follows:

fireAndProceed

The first run of a missed schedule is immediately implemented when the server is back online. Subsequent runs are discarded. After this, the normal schedule is resumed.

doNothing

All missed schedules are discarded and the normal schedule is resumed when the server is back online.

Schedule examples

The following example shows a schedule for reconciliation that is not enabled. When the schedule is enabled ("enabled" : true,), reconciliation runs every 30 minutes (1800000 milliseconds), and repeats indefinitely:

{
    "enabled": false,
    "persisted": true,
    "type": "simple",
    "repeatInterval": 1800000,
    "invokeService": "sync",
    "invokeContext": {
        "action": "reconcile",
        "mapping": "systemLdapAccounts_managedUser"
    }
}

The following example shows a schedule for liveSync enabled to run every 15 seconds, repeating indefinitely. Note that the schedule is persisted; that is, stored in the repository rather than in memory. If one or more liveSync runs are missed, as a result of the server being unavailable, the first run of the liveSync operation is implemented when the server is back online. Subsequent runs are discarded. After this, the normal schedule is resumed:

{
    "enabled": true,
    "persisted": true,
    "misfirePolicy" : "fireAndProceed",
    "type": "simple",
    "repeatInterval": 15000,
    "invokeService": "provisioner",
    "invokeContext": {
        "action": "liveSync",
        "source": "system/ldap/account"
    }
}

Scan data to trigger tasks

In addition to the fine-grained scheduling facility, IDM provides a task scanning mechanism. The task scanner lets you scan a set of properties with a complex query filter, at a scheduled interval, and then launches a script on the objects returned by the query.

For example, the task scanner can scan all managed/user objects for a specific date, and invoke a script that launches a task on the user object when that date is reached.

The task scanner runs a scheduled task that queries a managed object, then launches a script based on the query results. Scanning tasks are configured in the same way as standard scheduled tasks, as part of the schedule configuration, with the invokeService parameter set to taskscanner. The invokeContext parameter defines the scan details, and the task that should be launched when the specified condition is triggered.

Activate and deactivate accounts

The default IDM configuration includes two scanning tasks that activate and deactivate a user’s accountStatus, based on their activeDate and inactiveDate. The tasks run once a day by default.

Both tasks are disabled by default. To enable them, set "enabled" : true in the schedule configuration for each task.

The activate task

The activate task (conf/schedule-taskscan_activate.json) has the following configuration:

{
  "enabled" : false,
  "type" : "simple",
  "repeatInterval" : 86400000,
  "persisted" : true,
  "concurrentExecution" : false,
  "invokeService" : "taskscanner",
  "invokeContext" : {
    "waitForCompletion" : false,
    "numberOfThreads" : 5,
    "scan" : {
      "_queryFilter" : "((/activeDate le \"${Time.nowWithOffset}\") AND (!(/inactiveDate pr) or /inactiveDate ge \"${Time.nowWithOffset}\"))",
      "object" : "managed/user",
      "taskState" : {
        "started" : "/activateAccount/task-started",
        "completed" : "/activateAccount/task-completed"
      },
      "recovery" : {
        "timeout" : "10m"
      }
    },
    "task" : {
      "script" : {
        "type" : "text/javascript",
        "globals" : { },
        "source" : "var patch = [{ \"operation\" : \"replace\", \"field\" : \"/accountStatus\", \"value\" : \"active\" }];\n\nlogger.debug(\"Performing Activate Account Task on {} ({})\", input.mail, objectID);\n\nopenidm.patch(objectID, null, patch); true;"
      }
    }
  }
}

When you run this task, a user account is activated if both of the following are true:

  • Their activeDate is less than or equal to the value of Time.nowWithOffset.

  • Their inactiveDate is greater than or equal to the value of Time.nowWithOffset, or they do not have an inactiveDate set.

    Time.nowWithOffset is the current time plus the UTC time offset for the user’s geographical region.

The expire task

The expire task (conf/schedule-taskscan_expire.json) has the following configuration:

{
  "enabled" : false,
  "type" : "simple",
  "repeatInterval" : 86400000,
  "persisted" : true,
  "concurrentExecution" : false,
  "invokeService" : "taskscanner",
  "invokeContext" : {
    "waitForCompletion" : false,
    "numberOfThreads" : 5,
    "scan" : {
      "_queryFilter" : "((/inactiveDate lt \"${Time.nowWithOffset}\") AND (!(/activeDate pr) or /activeDate le \"${Time.nowWithOffset}\"))",
      "object" : "managed/user",
      "taskState" : {
        "started" : "/expireAccount/task-started",
        "completed" : "/expireAccount/task-completed"
      },
      "recovery" : {
        "timeout" : "10m"
      }
    },
    "task" : {
      "script" : {
        "type" : "text/javascript",
        "globals" : { },
        "source" : "var patch = [{ \"operation\" : \"replace\", \"field\" : \"/accountStatus\", \"value\" : \"inactive\" }];\n\nlogger.debug(\"Performing Expire Account Task on {} ({})\", input.mail, objectID);\n\nopenidm.patch(objectID, null, patch); true;"
      }
    }
  }
}

When you run this task, a user account is deactivated if both of the following are true:

  • Their inactiveDate (expiry date) is less than the value of Time.nowWithOffset.

  • Their activeDate is less than or equal to the value of Time.nowWithOffset, or they do not have an activeDate set.

    Time.nowWithOffset is the current time plus the UTC time offset for the user’s geographical region.

Create a new scanning task

The following example (openidm/samples/example-configurations/task-scanner/conf/schedule-taskscan_sunset.json) defines a scheduled scanning task that triggers a sunset script:

{
  "enabled" : true,
  "type" : "simple",
  "repeatInterval" : 3600000,
  "persisted": true,
  "concurrentExecution" : false,
  "invokeService" : "taskscanner",
  "invokeContext" : {
    "waitForCompletion" : false,
    "numberOfThreads" : 5,
    "scan" : {
      "_queryFilter" : "((/sunset/date lt \"${Time.now}\") AND !(/sunset/task-completed pr))",
      "object" : "managed/user",
      "taskState" : {
        "started" : "/sunset/task-started",
        "completed" : "/sunset/task-completed"
      },
      "recovery" : {
        "timeout" : "10m"
      }
    },
    "task" : {
      "script" : {
        "type" : "text/javascript",
        "file" : "script/sunset.js"
      }
    }
  }
}

The schedule configuration calls a script (sunset.js). To test the sample, copy this file to your project’s script directory or replace "file" : "script/sunset.js" with the script source ("source" : "contents of sunset.js"). The sample script marks all user objects that match the specified conditions as inactive. You can use this sample script to trigger a specific workflow, or any other task associated with the sunset process.

The task will only execute on users who have a valid sunset/date field. You can add a sunset/date field to user entries over REST. To make the field visible in the admin UI, you must add it to your managed object configuration.

This example command adds a sunset/date field to bjensen's entry, over REST:

curl \
--header "Content-Type: application/json" \
--header "X-OpenIDM-Username: openidm-admin" \
--header "X-OpenIDM-Password: openidm-admin" \
--header "Accept-API-Version: resource=1.0" \
--request POST \
--data '[{
  "operation" : "add",
  "field" : "sunset/date",
  "value" : "2019-12-20T12:00:00Z"
}]' \
"http://localhost:8080/openidm/managed/user?_action=patch&_queryFilter=userName+eq+'bjensen'"

The remaining properties in the schedule configuration are as follows:

The invokeContext parameter takes the following properties:

waitForCompletion (optional)

This property specifies whether the task should be performed synchronously. Tasks are performed asynchronously by default (with waitForCompletion set to false). A task ID (such as {"_id":"354ec41f-c781-4b61-85ac-93c28c180e46"}) is returned immediately. If this property is set to true, tasks are performed synchronously, and the ID is not returned until all tasks have completed.

maxRecords (optional)

The maximum number of records that can be processed. This property is not set by default so the number of records is unlimited. If a maximum number of records is specified, that number will be spread evenly over the number of threads.

numberOfThreads (optional)

By default, the task scanner runs in a multi-threaded manner; that is, numerous threads are dedicated to the same scanning task run. Multi-threading generally improves the performance of the task scanner. The default number of threads for a single scanning task is 10. To change this default, set the numberOfThreads property. The sample configuration sets the default number of threads to 5.

scan

The details of the scan. The following properties are defined:

_queryFilter

The query filter that identifies the entries for which this task should be run.

The query filter provided in the sample schedule configuration (/sunset/date lt \"${Time.now}\") AND !(/sunset/task-completed pr) identifies managed users whose sunset/date property is before the current date and for whom the sunset task has not yet completed.

The sample query supports time-based conditions, with the time specified in ISO 8601 format (Zulu time). You can write any query to target the set of entries that you want to scan.

For time-based queries, it’s possible to use the ${Time.now} macro object (which fetches the current time). You can also specify any date/time in relation to the current time, using the ` or `-` operator, and a duration modifier. For example: changing the sample query to `${Time.now + 1d}` would return all user objects whose `/sunset/date` is the following day (current time plus one day). Note: you must include space characters around the operator (`` or -`). The duration modifier supports the following unit specifiers:

  • s second

  • m minute

  • h hour

  • d day

  • M month

  • y year

object

Defines the managed object type against which the query should be performed, as defined in the managed.json file.

taskState

Indicates the names of the fields in which the start message, and the completed message are stored. These fields are used to track the status of the task.

started

specifies the field that stores the timestamp for when the task begins.

completed

specifies the field that stores the timestamp for when the task completes its operation. The completed field is present as soon as the task has started, but its value is null until the task has completed.

recovery (optional)

Specifies a configurable timeout, after which the task scanner process ends. For clustered IDM instances, there might be more than one task scanner running at a time. A task cannot be launched by two task scanners at the same time. When one task scanner "claims" a task, it indicates that the task has been started. That task is then unavailable to be claimed by another task scanner and remains unavailable until the end of the task is indicated. In the event that the first task scanner does not complete the task by the specified timeout, for whatever reason, a second task scanner can pick up the task.

task

Provides details of the task that is performed. Usually, the task is invoked by a script, whose details are defined in the script property:

type

The script type.

IDM supports "text/javascript" and "groovy".

file

The path to the script file. The script file takes at least two objects (in addition to the default objects that are provided to all IDM scripts):

input

The individual object that is retrieved from the query (in the example, this is the individual user object).

objectID

A string that contains the full identifier of the object. The objectID is useful for performing updates with the script as it allows you to target the object directly. For example: openidm.update(objectID, input['_rev'], input);.

For more information about using scripts, refer to Scripting function reference.

Manage scanning tasks

Once you create scanning tasks, you may want to update them. For example, you might want to trigger, cancel, or list the existing scanning tasks.

You can manage scanning tasks in IDM using:

Manage scanning tasks using REST

You can trigger, cancel, and monitor scanning tasks over the REST interface, using the REST endpoint openidm/taskscanner.

Create a scanning task

You can define a scanning task in a configuration file or directly over the REST interface. For an example of a file-based scanning task, refer to the file /path/to/openidm/samples/example-configurations/task-scanner/conf/schedule-taskscan_sunset.json.

The following command defines a scanning task named sunsetTask:

Trigger a scanning task

To trigger a scanning task over REST, use the execute action and specify the name of the task (effectively the scheduled job name). To obtain a list of task names, you can query the /openidm/scheduler/job endpoint. Note, however, that not all jobs are scanning tasks. Only those jobs that have which have the correct task scanner invokeContext can be triggered in this way.

The following example triggers the sunsetTask defined in the previous example:

curl \
--header "X-OpenIDM-Username: openidm-admin" \
--header "X-OpenIDM-Password: openidm-admin" \
--header "Accept-API-Version: resource=1.0" \
--request POST \
"http://localhost:8080/openidm/taskscanner?_action=execute&name=sunsetTask"
{
  "_id": "9f2564c8-193c-4871-8869-6080f374b1bd-2073"
}

For scanning tasks that are defined in configuration files, you can determine the task name from the file name, for example, schedule-task-name.json. The following example triggers a task named taskscan_sunset that is defined in a file named conf/schedule-taskscan_sunset.json:

curl \
--header "X-OpenIDM-Username: openidm-admin" \
--header "X-OpenIDM-Password: openidm-admin" \
--header "Accept-API-Version: resource=1.0" \
--request POST \
"http://localhost:8080/openidm/taskscanner?_action=execute&name=taskscan_sunset"
{
  "_id": "8d7742f0-5245-41cf-89a5-de32fc50e326-3323"
}

By default, a scanning task ID is returned immediately when the task is initiated. Clients can make subsequent calls to the task scanner service, using this task ID to query its state and to call operations on it.

To have the scanning task complete before the ID is returned, set the waitForCompletion property to true in the task definition file (schedule-taskscan_sunset.json).

Cancel a scanning task

To cancel a scanning task that is in progress, send a REST call with the cancel action, specifying the task ID. The following call cancels the scanning task initiated in the previous example:

curl \
--header "X-OpenIDM-Username: openidm-admin" \
--header "X-OpenIDM-Password: openidm-admin" \
--header "Accept-API-Version: resource=1.0" \
--request POST \
"http://localhost:8080/openidm/taskscanner/9f2564c8-193c-4871-8869-6080f374b1bd-2073?_action=cancel"
{
  "_id":"9f2564c8-193c-4871-8869-6080f374b1bd-2073",
  "status":"SUCCESS"
}

You cannot cancel a scanning task that has already completed.

List the scanning tasks

To retrieve a list of scanning tasks, query the openidm/taskscanner context path. The following example displays all scanning tasks, regardless of their state:

curl \
--header "X-OpenIDM-Username: openidm-admin" \
--header "X-OpenIDM-Password: openidm-admin" \
--header "Accept-API-Version: resource=1.0" \
--request GET \
"http://localhost:8080/openidm/taskscanner?_queryFilter=true"
{
  "result": [
    {
      "_id": "9f2564c8-193c-4871-8869-6080f374b1bd-2073",
      "name": "schedule/taskscan_sunset",
      "progress": {
        "state": "COMPLETED",
        "processed": 0,
        "total": 0,
        "successes": 0,
        "failures": 0
      },
      "started": "2017-12-19T11:45:53.433Z",
      "ended": "2017-12-19T11:45:53.438Z"
    },
    {
      "_id": "b32aafe5-b484-4d00-89ff-83554341f321-9970",
      "name": "schedule/taskscan_sunset",
      "progress": {
        "state": "ACTIVE",
        "processed": 80,
        "total": 980,
        "successes": 80,
        "failures": 0
      },
      "started": "2017-12-19T16:41:04.185Z",
      "ended": null
    }
  ]
  ...
}

Each scanning task has the following properties:

_id

The unique ID of that task instance.

name

The name of the scanning task, determined by the name of the schedule configuration file or over REST when the task is executed.

started

The time at which the scanning task started.

ended

The time at which the scanning task ended.

progress

The progress of the scanning task, summarized in the following fields:

failures

The number of records not able to be processed.

successes

The number of records processed successfully.

total

The total number of records.

processed

The number of processed records.

state

The current state of the task, INITIALIZED, ACTIVE, COMPLETED, CANCELLED, or ERROR.

The number of processed tasks whose details are retained is governed by the openidm.taskscanner.maxcompletedruns property in the conf/system.properties file. By default, the last 100 completed tasks are retained.

Manage scanning tasks using the admin UI

The task scanner queries a set of managed objects, then executes a script on the objects returned in the query result. The scanner then sets a field on a specific managed object property to indicate the state of the task. Before you start, you must set up this object type property on the managed user object.

In the example that follows, the task scanner queries managed user objects and returns objects whose sunset property holds a date that is prior to the current date. The scanner then sets the state of the task in the task-completed field of the user’s sunset property.

  1. Click Configure > Schedules, and click Add Schedule.

  2. Enable the schedule, and set the times that the task should run.

  3. Under Perform Action, select Execute a script on objects returned by a query (Task Scanner).

  4. Select the managed object on which the query should be run; in this case, user.

  5. Build the query that will be run against the managed user objects.

    The following query returns all managed users whose sunset date is prior to the current date (${Time.now}) and for whom the sunset task has not already completed (/sunset/task-completed pr):

    ((/sunset/date lt \"${Time.now}\") AND !(/sunset/task-completed pr))
  6. In the Object Property Field, enter the property whose values will determine the state of the task; in this case, sunset.

  7. In the Script field, enter an inline script, or a path to the file containing the script that should be launched on the results of the query.

    The sample task scanner runs the following script on the managed users returned by the previous query:

    var patch = [{ "operation" : "replace", "field" : "/active", "value" : false },{ "operation" : "replace", "field" : "/accountStatus", "value" : "inactive" }];
    openidm.patch(objectID, null, patch);

    This script essentially deactivates the accounts of users returned by the query by setting the value of their active property to false.

  8. Configure the advanced properties of the schedule described in Configure Schedules.
