Hi,

In our production XI3.0 SP16 server j2ee engine sutting down if we run many jobs at a time. Currently we are using j2ee 1.4.2_06 , this problem happend due to j2ee engine unstability.

SAP note says that need to upgrade j2ee from 1.4.2_06 to 1.4.2_11 . Not sure how to do this at OS level and after that where to change parameters for new java 1.4.2_11 settings.

Before that what files/folders need to take backup.Any idea how to upgrade.

-cheers !

Hi Lisa,

It's known problem in XI. But Apart from SP06, some more reasons are there....

First, Let me know the RAM size... As utilization increases, due to lack of memory, first J2EE engine stops... Because, J2EE engine needs lots of resources.

Normally, For 200 Documents/Hr needs 4GB to 6GB RAM.

Next, There are some standard memory parameter setting which should be set by Basis during installation. That can be changed as per requirement like paging area etc. (I am not sure, which one is required). But this too worked for us.
