What are Nodeapps Services in Oracle RAC


Nodeapps are standard set of oracle application services which are started automatically for RAC.

Node apps Include:

1) VIP.
2) Oracle Net listener.
3) Global Service Daemon.
4) Oracle Notification Service.

Nodeapp Services run on each node of the cluster and will switched over to other nodes through VIP during the failover.


Useful commands to maintain nodeapps services:

srvctl stop nodeapps -n NODE1 
[ STOP NODEAPPS  on NODE 1 ]
srvctl stop nodeapps -n NODE2            
[ STOP NODEAPPS  on NODE 2 ]

srvctl start nodeapps -n NODE1              
[ START NODEAPPS on NODE1  ]
srvctl start nodeapps -n NODE2             
[  START NODEAPPS ON NODE2 ]

srvctl status nodeapps                      
[Check the status of services on all nodes]
