Oracle RAC SRVCTL commands

What is srvctl? 

It is the Server Control Utility, we use SRVCTL to start and stop the database and instances, manage configuration information, and to add, move or remove instances and services.

These are some of the srvctl commands I frequently use, this is not a complete reference guide.

I organized the commands as follow:

To start a rac database
To stop a rac database
To check status and configurations
To start and stop instances
To start, stop and manage services
Start a rac database (order: nodeapps – asm – database)

srvctl start nodeapps -n nodename
srvctl start asm -n nodename
srvctl start database -d dbname

[options are: srvctl start database -d dbname -o open | -o mount | -o nomount]

Stop a rac database (order: database – asm – nodeapps)

srvctl stop database -d dbname -o immediate
options are: srvctl stop database -d dbname -o normal | -o transactional | -o immediate | -o abort

srvctl stop asm -n nodename
options are: srvctl stop asm -n nodename -o immediate

srvctl stop nodeapps -n nodename

To check status and configurations

srvctl status nodeapps -n nodename

srvctl config nodeapps -n nodename


srvctl status asm -n nodename
srvctl config asm -n nodename


srvctl status database -d dbname
srvctl config database -d dbname (shows instances name, node and oracle home)


srvctl status instance -d dbname -i instancename

srvctl status service -d dbname

To start and stop instances

srvctl start instance -d dbname -i instancename
srvctl stop instance -d dbname -i instancename

To create services

srvctl add service -s servicename -r preferrednode -a availablenode -d dbname -P BASIC -e SELECT -z 180 -w 5 -B NONE

To start, stop and manage services

srvctl status service -d dbname
srvctl config service -d dbname
srvctl start service -d dbname -s servicename
srvctl stop service -d dbname -s servicename

srvctl relocate service -d dbname -s servicename -i currentinstancename -t newinstancename [-f]
