Hi there, We have a highly concurrent websphere application where we have a lot of optimisticLockExceptions at the moment. I'd like to know if OpenJPA has a feature like EclipseLink where I can directly adress the OptimisticLock problem with @OptimisticLocking. (see for example http://buttso.blogspot.ch/2009/10/exploring-eclipselink-optimistlocking.html)
What we would need, is a feature which works like @OptimisticLocking(type=OptimisticLockingType.CHANGED_COLUMNS) (see link before). This describes a locking implementation which checks each changed field(and only those) if they were change during the process and only cause a optimistic lock if so. This means, the Update Query will have a longer where clause which checks for changes on only the updated fields. I found the very same feature request in JIRA https://issues.apache.org/jira/browse/OPENJPA-1451 where Patrick writes about Kodo's implementation, but isn't clear about how to do that eventually. Thanks, Lukas -- View this message in context: http://openjpa.208410.n2.nabble.com/Prevent-Optimistic-Locks-with-where-clause-tp7585480.html Sent from the OpenJPA Users mailing list archive at Nabble.com.
