IBM InfoSphere CDC instance fails
If the IBM InfoSphere CDC instance fails, replication on the subscriptions ends also. To recover, proceed as follows:
1 Restart the IBM InfoSphere CDC instance.
For instructions, see Starting and stopping IBM InfoSphere CDC.
2 Restart replication on the subscriptions.
Results
When restarted, replication on the subscriptions resumes and the databases are re-synchronized. Replication continues normally.
If this failure happens, the solidDB® server continues to process transactions until it reaches the limit specified by the LogReader.MaxLogSize parameter.
