PRCS-1007 : Server pool orcl already exists

This post is about fixing "PRCS-1007 : Server pool orcl already exists"

While upgrading my RAC database, i have removed database from oracle restart. But I need to add that back.

But, while registering the database again, i got the following errors.

[oracle@OEL7N1 ~]$ srvctl add database -d orcl -oraclehome /dboracle/app/oracle/product/12.2.0/dbhome_1  -dbtype RAC -spfile +DATA/ORCL/PARAMETERFILE/spfile.272.1070782447 -pwfile +DATA/ORCL/PASSWORD/pwdorcl.256.1070782021
PRCS-1007 : Server pool orcl already exists
PRCR-1086 : server pool ora.orcl is already registered

Removed the server pool.

Login as root user.

[root@OEL7N1 ~]# crsctl delete serverpool ora.orcl
[root@OEL7N1 ~]#

Let's try to add again.

[oracle@OEL7N1 ~]$ srvctl add database -d orcl -oraclehome /dboracle/app/oracle/product/12.2.0/dbhome_1  -dbtype RAC -spfile +DATA/ORCL/PARAMETERFILE/spfile.272.1070782447 -pwfile +DATA/ORCL/PASSWORD/pwdorcl.256.1070782021
[oracle@OEL7N1 ~]$
[oracle@OEL7N1 ~]$
[oracle@OEL7N1 ~]$ srvctl config
orcl
[oracle@OEL7N1 ~]$ srvctl status database -d orcl
Database is not running.

It works!!
