How can I know if JAVA stack is installed and running?

How can I know if the JAVA stack is installed and running?

I mean from the ABAP stack, while logged to the application server, how can I check if JAVA stack exists?

Thanks

Hi Leonardo,

You can also find the server details using following steps:

http:
<hostname:portn0>\index.html -> click on system information-> login with admin rights -> you can get all details about the installed server.

I should have been more clear on my question.

I needed to know if a JAVA stack was installed and running FROM the ABAP stack.

The transaction SMICM is a good answer. It gave me this result:

ICM Status: Running

Restart After Error true

Trace Level (0-3): 1

Created Worker Threads: 10 / 10 / 50 ( Current / Peak / Maximum )

Connections Used: 0 / 5 / 500 ( Current / Peak / Maximum )

7 2936 10.743 Running Administration

Does the ICM status running mean java installed and AS up?

Thanks for the asnwers guys!

Go to SMICM->GoTO-> Display Data->HTTP

Their you will find the J2ee engine parameters.

Hi,

The tool jcmon is very usefull to see current java stack condition. For details:

To start it:

jcmon pf=/usr/sap/<SID>/sys/profile/<SAPSID>_<INSTANCE_ID>_<HOST>

Award points if found usefull.

Hello Leonardo,

Both the SMICM method and the MMC method above will work. You can also check for the processes which are running at OS level.

So in Windows use the Task manager and check for Jlaunch pocesses

On Unix something like

ps -ef grep | jlaunch

If you are running on windows, then you can verify that the Java processes are running within the SAPMMC (you may have to be logged onto the server to see this -depending on how the system was setup).

Hope that helps.

Leonardo,

You can check that from SMICM.
