Replication with Infosphere CDC : IBM InfoSphere CDC replication failure scenarios : Communication link between primary solidDB® server and IBM InfoSphere CDC for solidDB® instance fails
  
Communication link between primary solidDB® server and IBM InfoSphere CDC for solidDB® instance fails
If the communication link between the primary solidDB® server and the IBM InfoSphere CDC for solidDB® instance fails, replication on the subscriptions ends also. However, the failure of the link alone is considered unlikely.
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.
For instructions, see IBM InfoSphere CDC documentation
Results
When restarted, replication on the subscriptions resume 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.
