Select for update skip locked from JPA level

Question

In my application - Oracle with JPA (EclipseLink), I\'m using the following expression to lock the subset of the records in some tables:

select * from MY_TABLE w         


        

Answer 1

I know this post is a bit old, but for the record, just as the accepted answer stated, "javax.persistence.lock.timeout" (org.hibernate.cfg.AvailableSettings#JPA_LOCK_TIMEOUT) set to "-2" (org.hibernate.LockOptions#SKIP_LOCKED) with Hibernate results in "SKIP LOCKED". However, this can be done at run-time without having to set any global settings.

Since 2.0 JPA allows to pass hints along like so

entityManager.find(MyType.class, id, LockModeType.PESSIMISTIC_WRITE, new HashMap() {{
        put("javax.persistence.lock.timeout", "-2");
    }});
