Stop the Single ASM Instance in Oracle Database

– To stop the ASM Instance, First we need to Stop the RDBMS & then we need to stop the ASM Instance

Check the status of database

[oracle@pri-db1 ~]$ srvctl status database -d testdb1
Instance testdb1 is running on node testdb1

Stop the RDBMS Database

[oracle@pri-db1 ~]$ srvctl status database -d testdb1
Instance testdb1 is not running on node testdb1

Check the ASM Instance

[oracle(testdb1)@testdb1 ~]$ . oraenv
ORACLE_SID = [testdb1] ? +ASM
The Oracle base remains unchanged with value /u01/oraclebase

[oracle(+ASM)@testdb1 ~]$ sqlplus / as sysasm

Verify

[oracle(+ASM)@testdb1 ~]$ srvctl status asm
