lti_update_trunc_point

The number of Log Transfer Language (LTL) commands sent before requesting a new LTM Locator from the Replication Server.

Default

10000

Value

An integer from 1 to 100000.

Comments

  • The value of the lti_update_trunc_point parameter is the number of LTL commands that Replication Agent sends to, before it requests a new LTM Locator (secondary truncation point) from the Replication Server.

  • Lower numbers cause Replication Agent to request a new LTM Locator from more often.

  • If the value of the truncation_type parameter is locator_update, setting the value of the lti_update_trunc_point parameter to a lower number causes automatic log truncation to occur more frequently.

  • 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 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.
