JVM in SolMan

[Former Member]

Hi Guys!

So in our landscape we have Solution Manager in a dual stack, and i've noticed that we have the JVM disabled, in all environments.

This doesn't seem to affect functionality since we mostly use it for ChaRM and RCA.

So I was wondering, is it just our landscape or is the jvm not used in a dual-stack?

Thanks!

Hi Marcos,

Can you check your Java stack and also wily , do you see them up and running, if yes  probably you do have another JVM installed on your system.

What is the OS you are using, let me know so that I can give you command to check.

Thanks and Regards

Hi Sachin!

We are running the AS's in Unix.

Through MMC If I open up the Solution Manager tree, it shows the SDM / dispatcher / server0 running.

But when I enter Tx SM52, it displays the message 'VMC is not loaded'. So maybe I'm doing something wrong?

Thanks!

Hi Marcos,

VMC is not loaded error is may be because of version mismatch, check KBA 1793427 - VMC Not loaded for more details.

If you see server process running, it means that it is using a JVM.

To check using which JVM it is being started, goto dev_server logs in work directory, in beginning you will see logs like below, which will give you JVM location and other information.

Hope this will help!
