Replication Guide and Reference

Problem determination facilities

This chapter provides basic information for using IBM Replication problem determination facilities, such as message explanation, trace and log records, and control table information. It also provides a high-level example of how to use the information to trace errors and a list of questions often asked by IBM service personnel that can help you to prepare to work with IBM Software Support. Use the information in this chapter to gather information about usage and operational errors so that you can work with IBM Software Support to resolve software problems.

IBM Replication provides the following facilities for problem determination:

• Error messages and SQL states for the DB2 Control Center, the Capture program, and the Apply program

• The Apply program trail table, log file, and trace file

• The Capture program trace table, log file, and trace file

• IBM Replication control tables and files

When using the problem determination facilities to test or debug your replication scenarios, we recommend that you:

• Attempt any new replications in a test environment.

• Stop other replication activity while gathering information about a problem to reduce the volume of data to sift through.

See Problem source identification questions for a list of questions that can help you to research the error condition.
