Migrate CCM application from one server machine to another with the same database server in Enterprise deployment topology using WAS

Body

How to migrate a CCM application from one server machine to another with the same database server in Enterprise deployment topology using WebSphere Application Server (WAS).

Standard deployment topologies overview

Example: A distributed environment where we have 5 server machines.

1st server machine for IHS,

2nd server machine for the database,

3rd server machine for DCC + RS,

4th server machine for JTS+RM+CCM and

5th server machine for LQE.

Expectation: CCM and RM are in the same server machine. How to move the CCM application to a new server machine?

Please find the procedure below referencing with the above scope of the requirement as an example.

3) Deploy the application

4) Restore the configuration\indices

5) Re-configure IHS for new RTC server.

6) Make sure you have the right JVM configured for the RTC applications.

Note: Two applications sharing the same JVM, needs more JVM to be set.

Attempting to use Collaborative Lifecycle Management on Windows operating system leads to NativeOutOfMemoryException (NOOME).

7) Set the new path to the indices folder in the teamserver.properties file (so that it picks the new location path after restoration).

Any feedback or suggestion based on specific scenario and your experience is appreciated.
