Adaptive Server log corruption can cause failures anywhere along the replication path.
RepAgent shuts down when it reads log data it cannot process.
The RepAgent shutting down is the most common symptom of a corrupt Adaptive Server log. In addition, the error log may reveal error messages that are inconsistent with the current operation; however, no specific log corruption error message is reported.
A component of the Replication Server shuts down.
When the RepAgent passes incorrect data to the Replication Server, Replication Server components, such as the Data Server Interface (DSI), may shut down. For instance, if the DSI encounters a mismatched data type and fails to resolve the differences, it shuts down.
Replicated data appears out of sync.
The procedures for determining log corruption and where the corruption occurs is complex. It requires knowledge of the log format as well as Adaptive Server and Replication Server internal components.
