The DG Broker is reporting some warnings for one of my databases in the Broker configuration.
DGMGRL> show database orcl Database - orcl Role: PRIMARY Intended State: TRANSPORT-ON Instance(s): orcl1 orcl2 orcl3 orcl4 orcl5 orcl6 orcl7 Database Warning(s): ORA-16789: standby redo logs configured incorrectly ORA-16789: standby redo logs configured incorrectly ORA-16789: standby redo logs configured incorrectly ORA-16789: standby redo logs configured incorrectly ORA-16789: standby redo logs configured incorrectly ORA-16789: standby redo logs configured incorrectly ORA-16789: standby redo logs configured incorrectly Database Status: WARNING
If these warnings were seen in the standby database, the most common reason is that the Standby Redo Logs are smaller than the primary’s Online Redo Logs. But note in the above output, this is from the primary database.
The reason for these warnings is quite simple…my primary does not have any SRL groups. Once I added the SRL groups, the warnings went away.
