CRSCTL Utility is used to managed oracle clusterware resources and components.
1. STOP & START CRS: ( run from root user)
$GRID_HOME/bin/crsctl stop crs $GRID_HOME/bin/crsctl start crs
2. Enable/Disable auto restart of CRS.
$GRID_HOME/bin/crsctl disable crs $GRID_HOME/bin/crsctl enable crs
3. Find the cluster name
$GRID_HOME/bin/cemutlo -n or $GRID_HOME/bin/olsnodes -c
4. Find grid version:
SYNATX – $GRID_HOME/bin/crsctl query crs softwareversion <hostname)
$GRID_HOME/bin/crsctl query crs softwareversion host-dbaclass1
5. check cluster component status
$GRID_HOME/bin/crsctl stat res -t $GRID_HOME/bin/crsctl check crs $GRID_HOME/bin/crsctl check cssd $GRID_HOME/bin/crsctl check crsd $GRID_HOME/bin/crsctl check evmd
6. Find voting disk location
$GRID_HOME/bin/crsctl query css votedisk
7. Find OCR location:
$GRID_HOME/bin/ocrcheck
8. Find cluster interconnect details
$GRID_HOME/bin/oifcfg getif app-ipmp0 172.21.39.128 global public loypredbib0 172.16.3.192 global cluster_interconnect loypredbib1 172.16.4.0 global cluster_interconnect select NAME,IP_ADDRESS from v$cluster_interconnects; NAME IP_ADDRESS --------------- ---------------- loypredbib0 172.16.3.193 loypredbib1 172.16.4.1
9. Check CRS status of local node
crsctl check crs CRS-4638: Oracle High Availability Services is online CRS-4537: Cluster Ready Services is online CRS-4529: Cluster Synchronization Services is online CRS-4533: Event Manager is online
10. Check status of all crs resourcs
$GRID_HOME/bin/crsctl stat res -t $GRID_HOME/bin/crsctl stat res -t -init
10. Check active version of cluster
crsctl query crs activeversion Oracle Clusterware active version on the cluster is [12.1.0.2.0]
11. Stop and start high availability service ( HAS)
crsctl stop has crsctl start has
12. Check CRS status of remote nodes
crsctl check cluster crsctl check cluster -all
13. Disk timeout from node to voting disk(disktimeout)
crsctl get css disktimeout CRS-4678: Successful get disktimeout 200 for Cluster Synchronization Services.
14. Network latency in the node interconnect (Misscount)
crsctl get css misscount CRS-4678: Successful get misscount 30 for Cluster Synchronization Services.
15. Move voting disk to another diskgroup:
crsctl replace votedisk +OCRVD Successful addition of voting disk 2e4ded6cee504fc8bf078b080fb7be6f. Successful addition of voting disk 8e87826024e24fffbf5add65c011fc66. Successful addition of voting disk e1ba56dedff84fa8bf5605e0302fc81e. Successful deletion of voting disk 2b7ce864c44d4fecbf60885a188290af. Successfully replaced voting disk group with +OCRVD. CRS-4266: Voting file(s) successfully replaced
16. Add another voting disk:
crsctl add css votedisk
17. Delete voting disk:
crsctl delete css votedisk
18 . Get ocr disk backup details
ocrconfig -showbackup
19 . Check whether standard or flex ASM
crsctl get cluster mode status Cluster is running in "standard" mode
20 . Check CRS configuation
crsctl config crs
21 . Find cluster configuration information:
$ crsctl get cluster configuration
Name : dbaclass-cluster
Configuration : Cluster
Class : Standalone Cluster
Type : flex
The cluster is not extended.

================================================================================
================================================================================21 . Find node roles in cluster
crsctl get node role status -all Node 'dbhost1' active role is 'hub' Node 'dbhost1' active role is 'hub'
22. crsctl has commands for standalone grid infrastrcuture
crsctl check has crsctl config has crsctl disable has crsctl enable has crsctl query has releaseversion crsctl query has softwareversion crsctl start has crsctl stop has
