Upgrading and changing server topology

Monali Jambhulkar (84●16●40) | asked Apr 27 '20, 1:29 a.m.

 Hello All


Currently we have server with Single server architecture( all application on one server  and DB only another server ) for CLM 6.0.6  with SQL server and WAS liberty profile.

Now we want to upgrade to CLM 6.0.6.1 with distributes server topology .(RM, QM, AM and CCM on one server, JTS,LQE, LDX and GC & JRS will be on different server )  and DB on third server .

Can you Please guide let what steps need to follow. Upgrade interactive guide is not giving direct help.

Please Suggest.

Thanks

I suggest to reconsider moving to 6.0.6.1 and move to 7.0 instead. This will provide you RM improvements plus number of other applications new features. Also, I would recommend that you have LQE as a seperate server as it requires larger memory footprint, see https://jazz.net/wiki/bin/view/Deployment/LifecycleQueryEngineBestPractices.

 Hi Monali,


To move to Distributed Topology You need to deploy IBM HTTP Server and configure reverse proxy.


During the configuration You will have to merge configuration files from different servers


I strongly suggest performing this process in following steps


1) Install second server (other servers) with the new applications
2) Perform basic configuration of the new servers (memory, etc)
3) Install IBM HTTP Server
4) Backup configuration files of applications You plan to move
5) Remove applications you want to move from the original server
6) Perform Plugin Merge
7) Setup HTTPS on IBM HTTP Server
8) Move archived application configuration files to the new servers
9) Reindex the data on the new servers

Important: If Your environment was using iFix please remeber to install this I fix on the new servers too.

Important 2: Do not mix this migration with upgrade to v7. First go distributed or first upgrade to v7, do not mix those two activities to avoid issues.

Important 3:

Please consider following topology:

Server 1: RM, QM, AM and CCM, JTS, LDX, GC
Server 2: LQE, JRS 
Server 3: DB

LQE should not be deployed on the same servers were user facing applications are installed. Reporting should have a separate server, if You have performance issues with other application then you should think about adding server 4.

If you use IBM HTTP then you should use default ports 80 and 443, you do not have to write them because web browser will automatically add it.

You should configure dns alias before you will set up public uri.

Hi,

You can put IHS on server 1, but this environment will be modified in the future when You will have more users or data.

There is a lot on server1 already so I suggest putting IHS on the seperate machine.

Hi Monali,


Assuming that you don't have IHS installed and you are trying to distribute the applications to different server.


Migration:

  • Below article provides detailed process of migrating CLM application to a new instance

https://jazz.net/wiki/bin/view/Deployment/MigratingCLMToANewEnvironment


  • After migration check if all the applications are accessible and working as expected.

Regards,

Bhagath
