ORA-16047 error occurred due to the log_archive_config parameter has not set on standby side.

StandBy Database:

SQL> show parameter LOG_ARCHIVE_CONFIG;

NAME TYPE VALUE

—————————————————————————————

log_archive_config string

In above query you can see that we have not setup the log_archive_config parameter on standby side database.Now we are going to set up the parameter.

SQL> alter system set LOG_ARCHIVE_CONFIG=’DG_CONFIG=(cdb1,standdb)’;

Primary Database:

SQL> show parameter LOG_ARCHIVE_CONFIG;

NAME TYPE VALUE

———————————————————————————————————-

log_archive_config string DG_CONFIG=(cdb1,standdb)

In above case cdb1 is the primary database and standdb is the standby database.

Apart from this also check the db_unique_name parameter on both the side.db_unique_name should be different in dataguard environment for primary and standby database.
