ORA-38891
cannot use DB_FLASHBACK_LOG_DEST without DB_FLASHBACK_LOG_DEST_SIZE
Cause
There are two possible cause for this error:
- The DB_FLASHBACK_LOG_DEST parameter was in use when no DB_FLASHBACK_LOG_DEST_SIZE parameter was encountered while fetching initialization parameter.
- An attempt was made to set DB_FLASHBACK_LOG_DEST with the ALTER SYSTEM command when no DB_FLASHBACK_LOG_DEST_SIZE was in use.
Action
Correct the dependency parameter definitions and retry the command.
