Configuration required for stateless session bean

[Nitin Deore]

Hi,
I am exposing my web services through stateless session beans.
These services may have users varying from 5-600.
Can anyone guide me getting configuration and the memory required for running these number of stateless session beans on the weblogic server 8.1 sp2?

Thanks in advance.

Regards,
Nitin

Hi
You sould setup the weblogic-ejb.xml as follows:

<stateless-session-descriptor>
<pool>
<max-beans-in-free-pool>600</max-beans-in-free-pool>
<initial-beans-in-free-pool>5</initial-beans-in-free-pool>
</pool>

The memory space relies on EJB's logic
Try it.

Thanks Jin.
This sets the number of stateless session bean instances at any point of time.
But my question is how would I know the memory/configuration required for perticular number of stateless session bean instances?

Hi
This is a great question but it's related to performance & tunning topics.

There is no silver bullet for answer this.

For default, you could use as minimun of 512 MB of Java heap and try it to tune the memory ...

In my experience, I use 1 GB with JRockit and things goes fine.
