    SimpleReadWriteEJBLock and Oracle

    Simon Godden Newbie

      As I understand it, SimpleReadWriteEJBLock obtains a shared read lock on the entity until someone request promotion to a write lock, at which point other readers are rolled back.

      I am wondering how you achieve this with Oracle, which does not support read locks.

      Is it the case that you do not use the database locking features (i.e. you do not use JDBC isolation levels) but instead you use synchronized locks within JBoss?

      So you are not dependent on the database features?
