CRSCTL Commands

CRSCTL Commands used to managed oracle clusterware resources and components.

CRSCTL provides cluster-aware commands with which you can perform check, start, and stop operations on the cluster. You can run these commands from any node in the cluster on another node in the cluster, or on all nodes in the cluster, depending on the operation.

STOP & START ‘CRS’ (RUN FROM root USER) :

$GRID_HOME/bin/crsctl stop crs
 
$GRID_HOME/bin/crsctl start crs

ENABLE/DISABLE AUTO RESTART OF ‘CRS’ :

$GRID_HOME/bin/crsctl disable crs
 
$GRID_HOME/bin/crsctl enable crs

FIND CLUSTER NAME :

$GRID_HOME/bin/cemutlo -n
or
$GRID_HOME/bin/olsnodes -c

FIND GRID VERSION :

SYNATX – $GRID_HOME/bin/crsctl query crs softwareversion <hostname)

$GRID_HOME/bin/crsctl query crs softwareversion host-dbaclass1

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

FIND ‘VOTING DISK’ LOCATION :

$GRID_HOME/bin/crsctl query css votedisk

FIND ‘OCR’ LOCATION :

$GRID_HOME/bin/ocrcheck

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

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

 CHECK STATUS OF all ‘CRS’ RESOURCE :

$GRID_HOME/bin/crsctl stat res -t
$GRID_HOME/bin/crsctl stat res -t -init

CHECK ACTIVE VERSION OF CLUSTER :

crsctl query crs activeversion
Oracle Clusterware active version on the cluster is [12.1.0.2.0]

STOP/START ‘HIGH AVAILABILITY SERVICE ( HAS)‘ :

crsctl stop has
 
crsctl start has

CHECK ‘CRS’ STATUS OF REMOTE NODES :

crsctl check cluster
 
crsctl check cluster -all

DISK TIMEOUT’ FROM NODE TO ‘VOTING DISK'(disktimeout) :

crsctl get css disktimeout
CRS-4678: Successful get disktimeout 200 for Cluster Synchronization Services.

NETWORK LATENCY IN THE NODE INTERCONNECT (Misscount) :

crsctl get css misscount
CRS-4678: Successful get misscount 30 for Cluster Synchronization Services.

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

ADD ANOTHER VOTING DISK :

crsctl add css votedisk

DELETE VOTING DISK :

crsctl delete css votedisk

GET ‘OCR’ DISK BACKUP DETAILS :

ocrconfig -showbackup

CHECK STANDARD OR FLEX ASM :

crsctl get cluster mode status
 
Cluster is running in "standard" mode

CHECK CRS CONFIGURATION :

crsctl config crs

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
