Configuration can be modified using the HTTP PATCH method. The PATCH request body is a JSON object formatted according to the SCIM patch request. The Configuration API, supports a subset of possible values for the path attribute, used to indicate the configuration attribute to modify.

The configuration object's attributes can be modified in the following ways. These operations are analogous to the dsconfig modify-[object] options.
  • An operation to set the single-valued description attribute to a new value:
    {  
      "op" : "replace",  
      "path" : "description",  
      "value" : "A new backend."
    }

    is analogous to:

    $ dsconfig set-backend-prop
      --backend-name userRoot \  
      --set "description:A new backend"
  • An operation to add a new value to the multi-valued jeProperty attribute:
    {
      "op" : "add",  
      "path" : "jeProperty",  
      "value" : "je.env.backgroundReadLimit=0"
    }

    is analogous to:

    $ dsconfig  set-backend-prop --backend-name userRoot \  
      --add je-property:je.env.backgroundReadLimit=0
  • An operation to remove a value from a multi-valued property. In this case, path specifies a SCIM filter identifying the value to remove:
    {
      "op" : "remove",  
      "path" : "[jeProperty eq \"je.cleaner.adjustUtilization=false\"]"
    }

    is analogous to:

    $ dsconfig set-backend-prop --backend-name userRoot \  
      --remove je-property:je.cleaner.adjustUtilization=false
  • A second operation to remove a value from a multi-valued property, where the path specifies both an attribute to modify, and a SCIM filter whose attribute is value:
    {
      "op" : "remove",  
      "path" : "jeProperty[value eq \"je.nodeMaxEntries=32\"]"
    }

    is analogous to:

    $ dsconfig set-backend-prop --backend-name userRoot \  
      --remove je-property:je.nodeMaxEntries=32
  • An option to remove one or more values of a multi-valued attribute. This has the effect of restoring the attribute's value to its default value:
    {
      "op" : "remove",  
      "path" : "id2childrenIndexEntryLimit"
    }

    is analogous to:

    $ dsconfig set-backend-prop --backend-name userRoot \  
      --reset id2childrenIndexEntryLimit
The following is the full example request. The API responds with the entire modified configuration object, which may include a SCIM extension attribute urn:unboundid:schemas:configuration:messages containing additional instructions:
PATCH /config/backends/userRoot
Host: example.com:5033
Accept: application/scim+json

  "schemas" : [ "urn:ietf:params:scim:api:messages:2.0:PatchOp" ],  
  "Operations" : [ {    
    "op" : "replace",    
    "path" : "description",    
    "value" : "A new backend."  
  }, {

    "value" : "je.env.backgroundReadLimit=0"  
  }, {    
    "op" : "remove",    
    "path" : "[jeProperty eq \"je.cleaner.adjustUtilization=false\"]"  
  }, {    
    "op" : "remove",    
    "path" : "jeProperty[value eq \"je.nodeMaxEntries=32\"]"  
  }, {    
    "op" : "remove",

  } ]
