The number of LTL commands sent before requesting a new LTM Locator from the Replication Server.
1000
An integer from 1 to 100000.
The value of the lti_update_trunc_point parameter is the number of LTL commands that Mirror Replication Agent sends to the Replication Server, before it requests a new LTM Locator (secondary truncation point) from the Replication Server.
Lower numbers cause Mirror Replication Agent to request a new LTM Locator from the Replication Server more often.
Each time Mirror Replication Agent requests a new LTM Locator from the Replication Server, the secondary truncation point in the Adaptive Server primary database is updated.
The value of the lti_update_trunc_point parameter is a trade-off between better system performance and longer recovery time:
Lower values reduce the time it takes to recover from a replication failure, but they may have an adverse affect on overall system throughput.
Higher values improve overall system throughput, but they may increase the time it takes to recover from a replication failure.
If Mirror Replication Agent is operating in an unreliable network environment, it may be prudent to set the lti_update_trunc_point parameter to a lower value to ensure faster recovery.
