Clusterware can be started and stopped manually by issuing the command /etc/init.d/init.crs (start stop enable disable)
1. /etc/rc.d/init.d/init.evmd
2. /etc/rc.d/init.d/init.cssd
3. /etc/rc.d/init.d/init.crsd
Once the above processes are running, they will automatically start the following services in the following order if they are enabled. This list assumes you are using ASM and have a service set up for TAF/load balancing.
1. The nodeapps (gsd, VIP, ons, listener) are brought online.
2. The ASM instances are brought online.
3. The database instances are brought online.
4. Any defined services are brought online
crsctl check crs
[oracle@wygora01 ~]$ crsctl check crsCSS appears healthyCRS appears healthyEVM appears healthy
crsctl stop crs
crsctl disable crs : This command will prevent CRS from starting on a reboot
Sequence of events to bring cluster database online
1. Start all services using “start -nodeapps”
2. Start ASM instnace using “srvctl start asm -n (node)”
3. Start RAC instances using “srvctl start instance -d (database) -I (instance)”
4. Finish up by bringing our load balanced/TAF service online “srvctl start service -d orcl -s RAC”
