Start, stop and check CRS (Cluster Ready Services)

Note. Start/stop need to be run as root from the CRS home.

Start CRS

crsctl start crs

Stop CRS

crsctl stop crs

Check CRS's status

crsctl check crs

See the status of the various services

crs_stat -t

Start/stop nodeapps

srvctl start nodeapps -n <node name>

srvctl stop nodeapps -n <node name>

Start/stop asm

srvctl start asm -n <node name>

srvctl stop asm -n <node name>

Start/stop a database (all nodes)

srvctl start database -d <database name>

srvctl stop database -d <database name>

Start/stop an individual instance

srvctl start instance -d <database name> -i <instance name>

srvctl stop instance -d <database name> -i <instance name>

Check the VIP config

srvctl config nodeapps -n <node> -a -g -s -l

Change the VIP address, subnetmask or interface

srvctl stop nodeapps -n <node1>

srvctl stop nodeapps -n <node2>

srvctl modify nodeapps -n <node1> -A <ip_address>/<net mask>/<interface>

srvctl modify nodeapps -n <node2> -A <ip_address>/<net mask>/<interface>

srvctl start nodeapps -n <node1>

srvctl start nodeapps -n <node2>

Locate the voting disk

crsctl query css votedisk

Retrive OCR (Oracle Cluster Registry) information

ocrcheck

To prevent a database starting at boot time

srvctl disable database -d <database name>

Change the private interconnect subnet

First find the interface which is in use as the interconnect - run as root from the crs home:

oifcfg getif

Make a note of the interface name (eth1 in the following example), then

run the following:

oifcfg delif -global eth1

oifcfg setif -global eth1/<your new subnet>:cluster_interconnect
