crsctl and srvctl commands

crsctl is a command-line tool for managing oracle clusterware and it enables us to check, start, and stop operations of the clusterware from any node.

Below are some of the crsctl command operations:

crsctl backup - back up voting disk for CSS 
crsctl check - check a service, resource, or other entity 
crsctl config - output autostart configuration 
crsctl debug - obtain or modify debug state 
crsctl delete - delete a resource, type, or other entity 
crsctl disable - disable autostart 
crsctl discover - discover DHCP server 
crsctl enable - enable autostart  
crsctl modify - modify a resource, type, or other entity 
crsctl query - query service state 
crsctl pin - pin the nodes in the nodelist 
crsctl relocate - relocate a resource, server, or other entity 
crsctl replace - replace the location of voting files 
crsctl start - start a resource, server, or other entity 
crsctl status - get status of a resource or other entity 
crsctl stop - stop a resource, server, or other entity

Example:

--To check the current status of all the resources
grid@dbsrv:~$ crsctl status res -t

--To start the Clusterware stack on all servers in the cluster or
    on one or more named server in the cluster:			   
 grid@dbsrv:~$ crsctl start cluster –all 
 grid@dbsrv:~$ crsctl start cluster –n dbhost1

--To start the Oracle High Availability Services daemon (OHASD)
grid@dbsrv:~$ crsctl start crs 

--To check the cluster status
grid@dbsrv:~$ crsctl check cluster -all
        dbsrv:
  CRS-4537: Cluster Ready Services is online
  CRS-4529: Cluster Synchronization Services is online
  CRS-4533: Event Manager is online

--To check the CRS status  
     grid@dbsrv:~$ 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
--To check the OHASD status
grid@dbsrv:~$ crsctl check has
      CRS-4638: Oracle High Availability Services is online

And srvctl is a utility that manages oracle resources managed by the oracle clusterware. The operations include enable, disable, start, stop, relocate, status, add, remove, modify, getenv, setenv, unsetenv, config, convert,and upgrade.

Example:

--To check the status of all clusters
       grid@dbsrv:~$ srvctl status database -db proddb
     Instance proddb1 is running on node proddb1
     Instance proddb2 is not running on node proddb2

--To stop all cluster nodes			
     grid@dbsrv:~$ srvctl stop  database -db proddb 

--To start the entire cluster 
           grid@dbsrv:~$ srvctl start database -db proddb

--To start instance 1 of the cluster 
     grid@dbsrv:~$ srvctl start instance -i proddb1 -d proddb

--To start instance 2 of the cluster
    grid@dbsrv:~$ srvctl start instance -i proddb2 -d proddb

-- To stop instance 1 of the cluster 
    grid@dbsrv:~$ srvctl stop instance -i proddb1 -d prodb2

--To check the SCAN configuration of the cluster
    grid@dbsrv:~$ srvctl config scan
      SCAN name: abc.com, Network: 1
      Subnet IPv4: 10.02.10.0/255.255.255.0/net0, static 
      Subnet IPv6:
      SCAN 0 IPv4 VIP: 10.02.10.44
      SCAN VIP is enabled.
      SCAN VIP is individually enabled on nodes:
      SCAN VIP is individually disabled on nodes:
      SCAN 1 IPv4 VIP: 10.02.40.45
      SCAN VIP is enabled.
      SCAN VIP is individually enabled on nodes:
      SCAN VIP is individually disabled on nodes:
      SCAN 2 IPv4 VIP: 10.02.10.46
      SCAN VIP is enabled.
      SCAN VIP is individually enabled on nodes:
      SCAN VIP is individually disabled on nodes

--To check the node VIP status on dbsrv1
   grid@dbsrv1:~$ srvctl status vip -n dbsrv1
       VIP dbsrv1-vip.abc.com is enabled
       VIP dbsrv1-vip.abc.com is running on node: dbsrv1

--To check the node apps on dbsrv1
    grid@dbsrv1:~$ srvctl status nodeapps -n dbsrv1
        VIP dbsrv1-vip.abc.com is enabled
        VIP dbsrv1-vip.abc.com is running on node: dbsrv1
         Network is enabled
         Network is running on node: dbsrv1
         ONS is enabled
         ONS daemon is running on node: dbsrv1
