Diagnosing problems with IBM InfoSphere Change Data Capture replication

Errors that are encountered during replication are reported in the IBM® InfoSphere Change Data Capture event logs.

Procedure

To view a summary of the generated errors that are captured in the InfoSphere CDC events log, issue the dmshowevents command with the appropriate options.
For example, when you issue the following command on the cdc-server-host, the results show a maximum of 100 event messages for all subscriptions that are associated with the instance:
/cdc-installation-dir/bin/dmshowevents -I cdc-instance-name -a -c 100

What to do next

For more details on the replication errors, you can use the raw log files.
