Move Concurrent Processing Server from one node to another in Oracle Apps 11i

Example:

Oracle E-Business Suite (11.5.10.2) with 2 nodes:

Node 1: Database and the Concurrent Processing

Node 2: Forms, Reports and Web Server.

Goal: To Move the concurrent processing from Node1 to node 2.

Requirement: Shared appl_top / Shared application tier file system. If not follow the Step 2 below.

How to perform:

1. This is recommended to be performed on a NON-PRODUCTION  system first with necessary backups.

2. Create a shared APPL_TOP by following Metalink Note 233428.1 for sharing the application tier files
system and allow the node 2 to share for concurrent manager node ( Node 1).

3. Edit context file on the Forms and Web node2 and change following context variables:

s_isConc from "NO" to " YES "
s_concstatus from "disabled" to " enabled "

On Node1: make the below changes

s_isConc from "YES" to "NO"
s_concstatus from "enabled" to "disabled"

4. Run autoconfig on all the APPS nodes.
