Oracle Error Message
ORA-16637: maximum number of Oracle error numbers for fast-start failover already reached
Reason for the Error
The broker could not enable any more Oracle error numbers for initiating a fast-start failover.
Solution
Use the DGMGRL CLI SHOW FAST_START FAILOVER command to help identify an Oracle error number that can be disabled before attempting to enable an additional error number for initiating a fast-start failover.
