Server Control Utility

Here we will discuss only about Server Control Utility (SRVCTL).

We can use SRVCTL to Add, start, stop, and Enable, Disable and remove instances and services.

Command Syntax:

Srvctl add

The SRVCTL add command add configuration in the OCR.

Add Database: - srvctl add database -d -o

Add Instance: - srvctl add instance -d -i -n

Add nodeapps: - srvctl add nodeapps -n -o -A /255.255.255.0

Add asm: - srvctl add asm -n -i -o

srvctl config

The SRVCTL config command displays the configuration stored in the OCR.

Config database: - srvctl config database -d

config nodeapps:- srvctl config nodeapps -n

config asm:- srvctl config asm -n

config listener:- srvctl config listener -n

srvctl start

Start database:- srvctl start database -d -o open

Start instance:- srvctl start instance -d -i

Start nodeapps:- srvctl start nodeapps -n

Start asm:- srvctl start asm -n -i

Start listener:- srvctl start listener -n

srvctl stop

Stop database: - srvctl stop database -d

Stop instance: - srvctl stop instance -d -i

Stop nodeapps: - srvctl stop nodeapps -n

Stop asm: - srvctl stop asm -n -i

Stop listener:- srvctl stop listener -n

srvctl status

srvctl status database

srvctl status database -d -v

srvctl status instance

srvctl status instance -d -i -v

srvctl status nodeapps

srvctl status nodeapps -n

srvctl status asm

srvctl status asm -n

srvctl remove

srvctl remove database

srvctl remove database -d

srvctl remove instance

srvctl remove instance -d -i

srvctl remove nodeapps

srvctl remove nodeapps -n

srvctl remove asm

srvctl remove asm -n -i

srvctl remove listener -n node1 -l lsnr01

AlterNet method to remove listener by using crs_unregister

1. $ crs_stat | grep NAME\= | grep lsnr
NAME=ora.rac1.LISTENER_RAC1.lsnr

NAME=ora.rac2.LISTENER_RAC2.lsnr

then
$ crs_unregister ora.rac1.LISTENER_RAC1.lsnr
$ crs_unregister ora.rac2.LISTENER_RAC2.lsnr
