Understanding Service Groups in R12.2

No comments

The Applications services are categorized into service groups according to the type of service provided. They were enabled and disabled as per the requirement. 
Link to earlier post Service group in R12.
In this post we are going to see the services group in R12.2 and changes when compared to previous versions.


Root Service Group: It contains Node Manager and not Oracle Process Manager (OPMN) as in previous version. Node manager services should run on all application nodes.

Web Administration Service Group: has been introduced in Release 12.2 and it contains WebLogic Administration server.  It is not supported to enable WebLogic Administration server on any other Application tier node except the node on which it was enabled during Rapid Install.
