In previous Oracle E-Business Suite releases, the Applications services were categorized into service groups according to the type of service provided. In Oracle E-Business Suite Release 12.2, this concept has been extended by the introduction of additional services and service groups.Here are the changes in Service Group R12.2
Most notably, the Web Administration service group has been introduced in Release 12.2.This service group contains WebLogic Administration server, and – unlike other service groups – can be enabled only on one of the Application tier nodes. In other words, 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.
Also, unlike previous releases of Oracle E-Business Suite Release 12.x, the Root Service Group now comprises Node Manager and not Oracle Process Manager (OPMN). In Oracle E-Business Suite Release 12.2, OPMN only manages Oracle HTTP Server. Consequently, it is now part of the Web Entry Point Services service group.
|Service Group||Service(s)||Service Control Script|
|Root Service||Node Manager||adnodemgrctl.sh|
|WebLogic Admin Server||adadminsrvctl.sh
|Web Entry Point Services||Oracle HTTP Server
Oracle Process Manager
|Web Application Services||oacore
|Batch Processing Services||Oracle TNS Listener
|Other Services||Forms Server
Oracle MWA Service
Enabling or disabling a service group
In Oracle E-Business Suite Release 12.2, all services except the Web Administration Service Group can be enabled or disabled on any or all Application tier nodes. This is done as follows:
1. Check the value of the ‘status’ context variable corresponding to the service group.
2. Change the value of this variable to ‘enabled’ to enable the service group, or to ‘disabled’ to disable the service group.
