ORA-16047: DGID mismatch between destination setting and target database

Primary database omrdb
Dataguard          omrdg

1- Check db_name and db_unique_name parameter on Primary and standby database
On Primary

SQL> show parameter db_name

NAME                    TYPE        VALUE
----------------------- ----------- ------------------------------
db_name                 string      omrdb

SQL> show parameter db_unique
NAME                    TYPE        VALUE
----------------------- ----------- ------------------------------
db_unique_name          string      omrdb

On Dataguard
SQL> show parameter db_name
NAME                  TYPE        VALUE
--------------------- ----------- ------------------------------
db_name               string      OMRDB

SQL> show parameter db_unique
NAME                  TYPE        VALUE
--------------------- ----------- ------------------------------
db_unique_name        string      omrdg


2- Check log_archive_config parameter
   SQL>show parameter log_archive_config

NAME                      TYPE        VALUE
------------------------- ----------- ------------------------------
log_archive_config        string      dg_config=(omrdb,omrdg)

3- Check log_archive_dest_2 parameter on primary database
SQL> show parameter log_archive_dest_2

NAME                     TYPE        VALUE
------------------------ ----------- ------------------------------
log_archive_dest_2       string      service=omrdg lgwr async valid_for=(online_logfiles,primary_role) db_unique_name=omrdb

4- Set the db_unique_name value correct to omrdg dataguard database
SQl>alter system set log_archive_dest_2='service=omrdg lgwr async valid_for=
(online_logfiles,primary_role) db_unique_name=omrdg' scope=spfile

5- Bounce the primary database and check alert log of standby database, it should show recovery like:
