How To Shutdown(stop)/Startup(start) CRS, OHAS, ASM, RDBMS Services on a RAC Cluster or OCI DBCS System
I have used below steps to restarting services on GRID in DBCS.
1) Connect to node #1, then please check if the CRS/OHAS & services are enabled to autostart as follow (repeat this step on each node):
# $GRID_ORACLE_HOME/bin/crsctl config crs
2) If not, then you can enable it as follow (repeat this step on each node):
# $GRID_ORACLE_HOME/bin/crsctl enable crs
3) Shutdown the services on each node as follow:
# $GRID_ORACLE_HOME/bin/crsctl stop crs
4) Verify the services were/are down (repeat this step on each node):
# $GRID_ORACLE_HOME/bin/crsctl status resource -t
5) Then start the services on node #1 as follow (only on first node):
# $GRID_ORACLE_HOME/bin/crsctl start crs
6) Wait 1 minute, then validate the services started & diskgroups were mounted (only on first node):
# $GRID_ORACLE_HOME/bin/crsctl status resource -t
7) Then start the services on node #2 as follow:
# $GRID_ORACLE_HOME/bin/crsctl start crs
8) Wait 1 minute, then validate the services started & diskgroups were mounted on node #2:
# $GRID_ORACLE_HOME/bin/crsctl status resource -t
9) If there are more nodes in the RAC, then repeat the same steps (7-8).
10) Then check the status of the clusterware globally as follows:
# crsctl check cluster -all
Sample output:
[root@asmnode1 ~]# crsctl check cluster -all**************************************************************asmnode1:CRS-4537: Cluster Ready Services is onlineCRS-4529: Cluster Synchronization Services is onlineCRS-4533: Event Manager is online**************************************************************asmnode2:CRS-4537: Cluster Ready Services is onlineCRS-4529: Cluster Synchronization Services is onlineCRS-4533: Event Manager is online**************************************************************
