[jboss-jira] [JBoss JIRA] Commented: (JBPM-1001) MS SQL server hibernate isolation level issue

    [ http://jira.jboss.com/jira/browse/JBPM-1001?page=comments#action_12366778 ] 

Aleksandar Kostadinov commented on JBPM-1001:
---------------------------------------------

Version 2000 is not supported by hibernate AFAIK as it doesn't support snapshot isolation at all. Steve Ebersole will know more about it.
We support hibernate on 2005 with the ms official jdbc driver with the option set in hibernate properties... that's why I've filed the issue. 
There is a chance you're not using a hibernate feature depending on the snapshot isolation level.
There is a chance you need to upgrade hibernate version.

In either case Steve/hibernate dev list should know better.

> When MS SQL server is used hibernate *requires*  "hibernate.connection.isolation 4096" in hibernate.properties. 
> Though when this option is set over 200 tests fail. See http://dev45.qa.atl.jboss.com:8585/hudson/job/JBPM.3_mssql2005-msjdbc/2/ and http://dev45.qa.atl.jboss.com:8585/hudson/job/JBPM.3_mssql2005-msjdbc/3/
> The first one is with the option and the second one without. You can see the difference. I've marked these builds so hudson will not delete them. If you need this option so you are able to test your changes I'll do. As well you could request an MS SQL server user account for manual testing.
> FYI I've set some database options so this isolation level is used by default (required for jtds as well as it doesn't support 4096 isolation value). But having the option should not break things as it is not breaking them for hibernate automated builds.
