STEP 1: Create blackout for the database
STEP 2: Take backup of spfile
SQL>
create pfile='/tmp/initORAPRIM.ora' from spfile;
File created.
STEP 3: stop database using srvctl utility
[oracle@oratest2 ~]$ srvctl stop database -d ORA_PRIM
[oracle@oratest2
~]$ srvctl status database -d ORA_PRIM
Instance
ORAPRIM1 is not running on node oratest2
Instance ORAPRIM2 is not running on node oratest1
STEP 4: Remove database resource from CRS
[oracle@oratest2 ~]$ srvctl remove database -d ORA_PRIM
Remove the
database ORA_PRIM? (y/[n]) Y
STEP 5: Start Only one instance using pfile backup
SQL> startup pfile='/tmp/initORAPRIM.ora'
ORACLE
instance started.

STEP 6: create spfile from pfile backup and start the database using spfile
SQL> create spfile from pfile='/tmp/initORAPRIM.ora';
File created.

STEP 7: change db_unique_name and global_name
SQL>
alter system set db_unique_name='OCIPRIM' scope=spfile sid='*';
System
altered.
SQL> alter database rename global_name to OCIPRIM;
Database
altered.
SQL> shut immediate
Database
closed.
Database
dismounted.
ORACLE
instance shut down.
SQL>
STEP 8: Add database to CRS level
[oracle@oratest2 ~]$ srvctl add database -d OCIPRIM -n oratest2 -o /u01/app/oracle/product/19c/db_1
[oracle@oratest2
~]$
STEP 9: Add instance to CRS level
[oracle@oratest2 ~]$ srvctl add instance -i OCIPRIM2 -n oratest2 -d OCIPRIM
[oracle@oratest2
~]$ srvctl status database -d OCIPRIM
Instance
OCIPRIM1 is not running on node oratest1
Instance
OCIPRIM2 is not running on node oratest2
STEP 10: Create dependency between database and ASM instance so that the database will be started after ASM instance starts.
[oracle@oratest2 ~]$ srvctl modify instance -i OCIPRIM1 -d OCIPRIM -n oratest1 -s +ASM1
PRKO-2207 :
Warning:-asminstance option has been deprecated and will be ignored.
[oracle@oratest2
~]$ srvctl modify instance -i OCIPRIM2 -d OCIPRIM -n oratest2 -s +ASM2
PRKO-2207 :
Warning:-asminstance option has been deprecated and will be ignored.
STEP 11: Change environment variable across all the instances of the database
STEP 12: add spfile at CRS level
[oracle@oratest2 ~]$ srvctl modify database -d OCIPRIM -spfile +DATA/OCIPRIM/PARAMETERFILE/spfileOCIPRIM.ora
[oracle@oratest2
~]$ srvctl config database -d OCRPRIM | grep -i spfile
[oracle@oratest2
~]$
