If you see ORA-16000 on clicking the Alert Log tab on a standby database then create the directory object on the primary and replicate it to the standby.
- Find background_dump_dest on the standby database
- Create two directories on the primary database (with and without the trailing slash) for example:
- Create directory QUEST_SOO_BDUMP_DIR_STDBY_1 as '/u01/app/oracle/diag/rdbms/spotl105/spotl105/trace/';
- Create directory QUEST_SOO_BDUMP_DIR_STDBY_2 as '/u01/app/oracle/diag/rdbms/spotl105/spotl105/trace';
- Ensure the directory has been replicated to the standby (this may take some time depending on your data guard setup)
- Click the Alert Log tab on the standby database
