[jboss-user] [Clustering] - obtain cluster lock

Hi all, Could I know what will be the available option for us to ensure that no two md bean instance reside in different cluster node accessing the same shared resources? The current approach i have identified is using the Hibernate LockMode.UPGRADE_NOWAIT. Whenever the md bean access the shared resource, it will acquire the lock via LockMode.UPGRADE_NOWAIT. | Thus whenever the following error happened , it signal that other md bean instance in different cluster node is accessing. | | org.hibernate.exception.LockAcquisitionException: could not execute query | at org.hibernate.exception.SQLStateConverter.convert(SQLStateConverter.java:87) | at org.hibernate.exception.JDBCExceptionHelper.convert(JDBCExceptionHelper.java:43) | at org.hibernate.loader.Loader.doList(Loader.java:2147) Is the above mentioned approach recommended? Or any other mechanism is better in this scenario? Thanks! My deploy env JBOSS 405 oracle 10 niefeng View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4264364#...
