SYNTAX – srvctl stop instance -d db_unique_name [-i “instance_name_list”]} [-o stop_options] [-f]
e.g
4. START AN INSTANCE
SYNTAX – srvctl start instance -d db_unique_name [-i “instance_name_list”} [-o start_options]
e.g
5. REMOVING DB FROM CRS:

e.g
6. ADDING DB IN CRS :
SYNTAX – srvctl add database -d db_unique_name -o ORACLE_HOME [-p spfile]
e.g
7. REMOVING AN INSTANCE FROM CRS:
SYNTAX – srvctl remove instance -d DB_UNIQUE_NAME -i INSTANCE_NAME
e.g
8.ADDING AN INSTANCE TO CRS:
SYNTAX – srvctl add instance –d db_unique_name –i inst_name -n node_name
e.g
9. Enable/disable auto restart of the instance
10. Enable/disable auto restart of the database
11. ADDING A SERVICE:
SYNTAX – srvctl add servicec -d {DB_NAME} -s {SERVICE_NAME} -r {“preferred_list”} -a {“available_list”} [-P {BASIC | NONE | PRECONNECT}]

EXAMPLE: (Relocating service PRDB_SRV from PREDB2 to PREDB1)
16. Check the status of service
SYNTAX – srvctl status service -d {database_name} -s {service_name}
