Out of Memory Error after installation

[Former Member]

Hello SAPfans!

I am trying to use my newly installed webAS 6.40. When I deploy a simple webdynpro application, the server takes a while then reports that it has ran out of memory!

The stacktrace only contains of "java.lang.OutOfMemoryError".

Please advise.

Best regards, Peter

how much physical memory do you have on the machine. It needs at least 512MB. If you do have that please increase the vm memory settings using the config tool.

Hi, we have 4 GB of internal memory on the box.

Where exactly do you mean to update the VM settings?

I set the value when installing to a max heapsize of 1024 MB...?

Best regards, Peter

take a look at note 723909, there are some important vm-parameters for an EP-installation.

I use (without any problems with 1,5GB RAM):

-Xms170m

-Xmx170m

-XX:NewSize=128m

-XX:MaxNewSize=128m

-XX:PermSize=192m

-XX:MaxPermSize=192m

to edit them, start the configtool in <install-dir>/configtool/

with 4GB ram you can use much higher values, of course

Perfect! Thank you for the tip!

I added the lines

-XX:PermSize=64m

-XX:MaxPermSize=128m

in "java parameters" and now the webAS seems to be content.

I think you got the 10 points appointed to this answer, right?

However, do you have a document describing these parameters and what they stand for?

if you use the java VM from sun, surf to http://java.sun.com/docs/hotspot/VMOptions.html

but I don't recommend to set any of these parameters other than SAP tells you...
