5 Troubleshooting Replication 

The following sections in this chapter describe how to troubleshoot problems you may encounter when replicating databases:

• Unable to Create a Replication Scheme

• Unable to Alter a Replication Scheme

• Unable to Start or Stop Replication Agent

• Replication Does Not Work

• Replication Unresponsive, Appears Hung

• Poor Replication or XLA Performance

• Problems Using ttRepAdmin

• Problems with Conflict Checking

• Problems with Parallel Replication

Note:

Error log messages from the replication agent daemon are designated by REP in the message, as shown in several examples in this chapter. These messages are enabled unless you disable the REPLICATION component of the ttDaemonLog utility. See ttDaemonLog in Oracle TimesTen In-Memory Database Reference for information about ttDaemonLog options.
