Checking the Physical Standby Database

During an incremental synchronization with Oracle serving as the source database, DRS checks whether the source database is a physical standby database.

Item to Be Confirmed

The source database is a physical standby database, where data of the LOB type cannot be parsed.
The physical standby database does not generate logs. It replicates logs from the primary database. Check whether supplemental logging of the primary database meets the incremental synchronization requirements.

Handling Suggestion

Change the Oracle startup mode and restart the Oracle database.
Check whether supplemental logging of the primary database meets the incremental synchronization requirements. For details, see How Do I Check Supplemental Logging of the Source Oracle Database?
