Re: [xwiki-users] reduce -Xmx after trying too large -Xmx?

Hallo! - Using HSQLDB from latest xwiki-enterprise-installer-generic-3.0-milestone-3-standard.jar - in Windows XP - java Standard Edition Runtime Environment Version 6 I have increased -Xmx in start_xwiki.bat too much from 300mb to 900m. After reducing back to 300m i get the HTTP ERROR 500. What can i do to go back to Xmx=300m without export/import? Volker HTTP ERROR 500 Problem accessing /xwiki/bin/view/Main/.
