OCI-16723
Modification to RedoRoutes property may result in a terminal member having a higher priority than the cascading member.
Cause
The change to the RedoRoutes property for the specified member resulted in a terminal member having a higher priority setting than the cascading member.
Action
Use the DGMGRL CLI SHOW ALL MEMBERS RedoRoutes command to check the value of the RedoRoutes property for all members. Use the DGMGRL SHOW CONFIGURATION WHEN PRIMARY IS command for each database that may become a primary database to ensure that all members continue to receive redo data after any role change.
OCI-16723
setting AlternateLocation property conflicts with the redo transport setting
Cause
The standby database was not using standby redo logs, and the redo transport service to the standby database is set to a nonzero value for the ReopenSecs property and a value of zero for the MaxFailure property. In this case, the redo transport service will attempt to send redo data to the standby database indefinitely and never switch to the alternate destination.
Action
Any one of the following actions will solve the problem:
- add standby redo logs to the standby database.
- set ReopenSecs property to zero.
- set MaxFailure property to a nonzero value.
After performing one of the above actions, reset the standby database AlternateLocation property.
