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 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
attribute is changed three times, three notifications will be sent in the order they
appeared in the change log.
