Debugging LTL

LTL (Log Transfer Language) is the syntax used to communicate or distribute replication data to Replication Server.

LTL is the principal output from a Replication Agent.

To debug problematic LTL:

  1. Log in to the running Replication Agent instance using the administrator login.
  2. Verify that the Replication Agent instance is in Admin state:
    ra_status
    If the Replication Agent instance is not in the Admin state, quiesce the Replication Agent instance:
    quiesce
  3. Set the values of these Replication Agent configuration parameters for the primary database:
    trace LTITRACELTL, true
  4. Start replication for the Replication Agent instance:
    resume
  5. When new replication activity is generated, check the LTITRACELTL.log file in the log directory to debug your problem.
