What you need to know

Maintenance user ID

The Replication Server get maintenance user command returns the Replication Server maintenance user ID.

Replication Server uses the maintenance user ID to update tables with replicated data in the database monitored by Replication Agent.

By default, Replication Agent does not pass transactions made by the maintenance user ID to Replication Server for replication. To replicate changes made by this user, set the value of the LTM for MVS LTM_process_maint_uid_trans configuration parameter to Y to specify that Replication Agent replicate all logged changes made by the Replication Server maintenance user.

LTM Locator and origin queue ID

The Replication Server get truncation command returns a value called the LTM Locator, which is the origin queue ID associated with the transaction operation last saved by Replication Server.

Replication Extract uses the LTM Locator value to determine the location in the log where replication should begin.

Replication Server has successfully saved all transactions up to this LTM Locator value in its stable queue; Replication Agent can safely ignore all transactions before this point in the log.
