First check whether the machine has sufficient memory available to accommodate ABAP and Java.

If not there is no point adding more memory to heap as the result will be OOM.

First you need to find out the memory used by ABAP, Java and the database.

Hi,

Can you please explain more about the functionality that this port is handling. Are you using this portal to download large reports ore pdf.

Hi,

This is wrong sizing done for your solution manager . Please check the sizing excel sheet for the solution manager.

From message we can clearly see that the Out of memory was caused by running out of memory in perm space. The perm space is located outside the heap. I would like to mention of the fact that more permanent space is needed if additional applications are deployed or the complexity of the applications grows.

Can you please check increase perm size with the java config tool on all server nodes of this system.

-XX:MaxPermSize and PermSize

Check SAP Note 710146 - How to change J2EE Engine JVM Settings.

Also compare the settings for your system with the recommendations given in note:

1603093 - "SAP JVM 4.1 parameters NetWeaver 2004 and 7.0"
