SDM and Java

Hi All,

I have facing 2 issues,

1. Is there any way to restart the SDM server seperately as I am facing the following problem while login in and while stopping the server.

Shutdown failed: Cannot shutdown server. There are active sessions: Session id 12 / An administrator logged in via GUI / /

Could not shutdown server: Could not shutdown Server(4)

Details: Shutdown failed: Cannot shutdown server. There are active sessions: Session id 12 / An administrator logged in via GUi

Processing error. Return code: 4

2. Also when i start the SDM, it shows the 'Starting /usr/java/bin/java' ' - Xmx256'

I think it is using only 256 Mb of RAM? I have opened configtool and changed the server properties to 512 and heap to 2048, but still the same. Is there any other parameter to change the java setting?

Thanks & regards,

Prashant
