Notification mode, a configuration setting on the Sync Pipe, requires a one-way directional Sync Pipe from a source endpoint topology to a target client application.
PingDataSync detects the changes in the PingDirectory server’s LDAP change
log, filters the results specified in the Sync Classes, applies any distinguished name (DN) and attribute mappings, then reconstructs the change information from the
change log attributes. A server extension picks up the notification arguments from the
SyncOperation interface (part of the Server SDK) and converts the data
to the desired output format. The server extension establishes the connections and protocol
logic to push the notification information to the client applications or services. All of
the operations, administration, and management functions available in standard mode, such
as monitoring, (LDAP, JMX, SNMP), alerts (JMX, SNMP, SMTP), and logging features are the
same for notification mode.
The Server SDK includes documentation and examples on how to create a directory server extension to support notification mode.
For a given entry, PingDataSync sends notifications in
the order that the changes occurred in the change log even if a modified attribute has been
overwritten by a later change. For example, if an entry’s telephoneNumber
attribute is changed three times, three notifications will be sent in the order they
appeared in the change log.
