Stop CRS:
crsctl stop crs (normal)
crsctl stop crs -f (force)
Start CRS:
crsctl start crs
Checking Resource Status for CRS: (replaces crs_stat -t -v in Oracle11gR2)
crsctl status resource -t or
crsctl stat res -t or
crsctl stat res -t -init (only local node status)
** Different resources can be filtered by the following commands:
crsctl stat res -t -w "TYPE = ora.database.type" (Database)
crsctl stat res -t -w "TYPE = ora.asm.type" (ASM)
crsctl stat res -t -w "TYPE = ora.scan_listener.type" (Scan Listener)
crsctl stat res -t -w "TYPE = ora.scan_vip.type" (Scan VIP)
crsctl stat res -t -w "TYPE = ora.cvu.type" (Cluster Verification Utility)
ps. equal sign (=) should have space in between
