If your source database shutdown fails during synchronization, check your database log file for messages.

To check the success of synchronization, search the replication source database logs for messages like the following:

Table 1. Synchronization messages
Error code Message Result

10436 The source database [db-name] and the target database [db-name] on host [host-name] are synchronized. Synchronization succeeded.
20257 Replication server has verified that all connected replication target databases are synchronized with the replication source database. Synchronization succeeded.
