[xwiki-users] Migration from Xwiki 3.1.1 to 3.3 attempt failed: 'thrown exception'

Hi, I have just tried to get my Xwiki version updated from 3.1.1 to 3.3. For some reason as I've posted about I had major errors in the upgrade process from 2.x over to 3.1.1 as my admin panel went funny after the upgrade. Now in my attempt Tomcat's log shows this: www# cat stdout.log | tail at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:191) [catalina.jar:6.0.35] at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127) [catalina.jar:6.0.35] at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) [catalina.jar:6.0.35] at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) [catalina.jar:6.0.35] at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:293) [catalina.jar:6.0.35] at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:859) [tomcat-coyote.jar:6.0.35] at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:602) [tomcat-coyote.jar:6.0.35] at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:489) [tomcat-coyote.jar:6.0.35] at java.lang.Thread.run(Thread.java:619) [na:1.6.0_07] 2012-01-19 19:34:43,367 [http://www.optiplex-networks.com/xwiki/bin/view/Main/] WARN o.a.s.a.RequestProcessor - Unhandled Exception thrown: class com.xpn.xwiki.XWikiException And the browser shows this: javax.servlet.ServletException: com.xpn.xwiki.XWikiException: Error number 3 in 0: Could not initialize main XWiki context Wrapped Exception: Error number 3001 in 3: Cannot load class com.xpn.xwiki.store.migration.hibernate.XWikiHibernateMigrationManager from param xwiki.store.migration.manager.class Wrapped Exception: Error number 0 in 3: Exception while hibernate execute Wrapped Exception: Could not create a DBCP pool.

A quick google yielded to the same error but with Oracle DB which gave this as a fix: <property name="hibernate.connection.SetBigStringTryClob">true</property> <property name="hibernate.jdbc.batch_size">0</property> I'm wondering if it's the same for postgres??? I will atempt to include the statements but I believe I will need to restore my Xwiki instance from my backups at this current moment in time! Regards, Kaya
