RAC Useful Srvctl Commands

Use the Server Control (SRVCTL) utility to manage various components and applications in your cluster.

This appendix contains reference information for Server Control commands, including utility usage information and a comprehensive listing of the SRVCTL commands.

SRVCTL is installed on each node in a cluster by default. To use SRVCTL, log in to the operating system of a node and enter the SRVCTL command and its parameters in case-sensitive syntax.

• Only use the version of SRVCTL that is provided with Oracle Database 12c on Oracle RAC databases that are created for or upgraded to Oracle Database 12c. The version of SRVCTL must be the same as the version of the object (listeners, Oracle ASM instances, Oracle RAC databases and their instances, and services) being managed. To ensure the versions are the same release, run SRVCTL commands from the Oracle home of the database or object you are managing.
• SRVCTL does not support concurrent executions of commands on the same object. Therefore, run only one SRVCTL command at a time for each database, service, or other object.
• When specifying a comma-delimited list as part of a SRVCTL command, there should not be any spaces between the items in the list.

1. STOP DATABASE :

SYNTAX – srvctl stop database -d db_name [-o stop_options] where stop_options is normal/immediate(default)/transactional/abort

e.g

srvctl stop database -d PRODB -o normal
srvctl stop database -d PRODB -o immediate
srvctl stop database -d PRODB -o transactional
srvctl stop database -d PRODB -o abort

2. START DATABASE
SYNTAX – srvctl start database -d db_name [-o start_options] where start_option is nomount/mount/open(default)

e.g

srvctl start database -d PRODB -o nomount
srvctl start database -d PRODB -o mount
srvctl start database -d PRODB -o open

3. STOP AN INSTANCE

SYNTAX – srvctl stop instance -d db_unique_name [-i “instance_name_list”]} [-o stop_options] [-f]
e.g

srvctl stop instance -d PRODB -i PRODB

4. START AN INSTANCE

SYNTAX – srvctl start instance -d db_unique_name [-i “instance_name_list”} [-o start_options]
e.g

srvctl start instance -d PRODB -i PRODB1

5. REMOVING DB FROM CRS:
SYNTAX – srvctl remove database -d db_unique_name [-f] [-y] [-v]
e.g

srvctl remove database -d PRODB -f -y

6. ADDING DB IN CRS :
SYNTAX – srvctl add database -d db_unique_name -o ORACLE_HOME [-p spfile]
e.g

srvctl add database -d PRODB -o /u01/app/oracle/product/12.1.0.2/dbhome_1 -p +DATA/PRODDB/parameterfile/spfilePRODB.ora

7. REMOVING AN INSTANCE
SYNTAX – srvctl remove instance -d DB_UNIQUE_NAME -i INSTANCE_NAME
e.g

srvctl remove instance -d PRODB – I PRODB1

8.ADDING AN INSTANCE
SYNTAX – srvctl add instance –d db_unique_name –i inst_name -n node_name
e.g

srvctl add instance -d PRODB – i PRODB1 -n rachost1

9. Enable/disable auto restart of the instance

srvctl enable instance -d DB_UNIQUE_NAME-i INSTANCE_NAME
srvctl disable instance -d DB_UNIQUE_NAME-i INSTANCE_NAME

10. Enable/disable auto restart of the database

17. Check the configuration of service
SYNTAX – srvctl config service -d {database_name} -s {service_name}

srvctl config service -d PREDB -s PRDB_SVC
