J2EE startup framework and J2EE

[Former Member]

I have changed some Java VM parameters.

To make above change effective, I have to re-start the J2EE instance.

But my co-worker (who left my company) wrote in his document

" For the SAP J2EE startup framework, it's NOT sufficient to re-satrt the J2EE

instance" to activate above change.

I did some research on J2EE startup framework. I think it is no longer used in NW7.0

Could you help me

-- how do I know a system has SAP J2EE startup framework (I believe it is a concept prior to 7.0 version).

Our system is NW7.0.

-- If it is a J2EE stratup framework, how do I activate above change?

Thanks a million!

Hello Christy

SAP Netweaver 7.0 still has J2EE Startup and Control framework.

When you change a property normally the tool prompts that a restart is required. Normally you get a description of what kind of restart is needed. "A cluster restart is needed" for example meaning you have to stop/start your J2EE cluster.

If you are working on a dual stack you can stop/start through transaction SMICM under menu item Administration --> J2EE Cluster --> Send Hard Shutdown --> With Restart. That will hard restart your J2EE cluster and your parameter change (done in configtool I assume) will be activated once the J2EE cluster has restarted.

If you are working on a single stack SAP system you can stop/start using command prompt stopsap JC<instance number> or through the SAP Management Console.

You can check the activate VM parameters through the http://<hostname>:<j2ee port>:/index.html page under system information --> VM parameters for the node for which you have made a change.

Kind regards

Thank you very much!

Basically you have answered my question. The only problem is that I cannot

find my ECC6 and NW70 have J2EE startup framework OR not. I have researched

lots of document but now way to tell.

Best regards.

Hello Christy

Probably because the correct name is J2EE startup and control framework.

You can find it using the search function on help.sap.com.

Kind regards
