List all srvctl commands

List all srvctl commands

srvctl –h

Shutdown service

srvctl stop service –d database_name

Shutdown the database on all nodes

srvctl stop database –d database_name

Shutdown a specific instance

srvctl stop instance –d database_name -i instance_name

Shutdown nodeapps (includes listener)

srvctl stop nodeapps –n node_name

! node_name is usually the hostname of the machine

Shutdown the listener

srvctl stop listener –n node_name

Shutdown ASM

srvctl stop asm –n node_name

To Startup, replace stop with start.

If you shutdown the database it will stop the service since the service is dependent upon the database. The reverse is also true. If you startup the service it will implicitly startup the database.

To check to see if your services are running.
