How to start/stop RAC componants

How to Stop/Start RAC components
In this article, I am going to explain how to stop/start rac components. This is my environment:

My db version : 11.2.0.3
My Operating System : AIX 6.1
My servers hostname : node1-node2
My database name : TEST
My instance name : TEST1-TEST2

Here is the some basic  commands, for commands details&options  please review Reference docs:

Oracle High Availability Services

– disable/enable Oracle HAS.
Use the “crsctl enable/disable has” command to disable automatic startup of the Oracle High Availability Services stack when the server boots up.

To can see current settings for Oracle High Availability Services stack when the server boots up, follow:

[root@node1]crsctl config has
CRS-4622: Oracle High Availability Services autostart is enabled.

or

[root@node1]cat /etc/oracle/scls_scr/node1/root/ohasdstr
enable

So as you can see my current setting is enable.If your system shown disable than :

For Disable:
[root@node1]crsctl disable has
CRS-4621: Oracle High Availability Services autostart is disabled.

[root@node1] crsctl config has
CRS-4621: Oracle High Availability Services autostart is disabled.

# cat /etc/oracle/scls_scr/node1/root/ohasdstr
disable

For Enable:
[root@node1]crsctl enable has
CRS-4621: Oracle High Availability Services autostart is enabled.

Check new setting:

[root@node1] crsctl config has
CRS-4621: Oracle High Availability Services autostart is enabled.

[root@node1] cat /etc/oracle/scls_scr/node1/root/ohasdstr
enable

Stop the Oracle clusterware stack

You can use below commands:
With root user:

crsctl stop crs or crsctl stop has

Start the Oracle clusterware stack

You can use below commands:
With root user:
crsctl start crs or crsctl start has

[root@node1] crsctl start crs
CRS-4123: Oracle High Availability Services has been started.

Start the Oracle Database
To start all Oracle RAC instances for a database:
[oracle@node1]
$ORACLE_HOME/bin/srvctl start database -d db_name
PS: db_name is the name of the database this command is starting all the instances

Stop the Oracle Database
To shut down all Oracle RAC instances for a database:
[oracle@node1]
$ORACLE_HOME/bin/srvctl stop database -d db_name
PS: db_name is the name of the databasethis command is starting all the instances

Start the Oracle Instance:

[oracle@node1]
$ORACLE_HOME/bin/srvctl start database -d db_name -i instance_name

Stop the Oracle Instance:

[oracle@node1]
$ORACLE_HOME/bin/srvctl stop database -d db_name -i instance_name
Stop/Start Listener-SCAN_LISTENER

srvctl stop/start listener -n node1
srvctl stop/start listener -n node2
srvctl stop scan_listener

Stop ASM

srvctl stop asm [-o stop_options] [-f]
srvctl stop asm -n node1
