DBA_APPLY_ERROR_MESSAGES

Displays information about the individual messages in all the error transactions generated by all applied processes in the database.

DBA_GG_AUTO_CDR_TABLES

Provides details about all the tables configured for Oracle GoldenGate automatic conflict detection and resolution (CDR).

If you are not yet taking advantage of the GoldenGate active/active feature, I highly recommend you review it and send me any questions. Making your applications highly available, fault-tolerant, and performing flawlessly can provide you with many benefits.
