[jira] [Created] (OPENJPA-2194) ReplicationDriver doesn't switch to
write mode when using executeUpdate
Daniel Persson created OPENJPA-2194:
---------------------------------------
Summary: ReplicationDriver doesn't switch to write mode when using executeUpdate
Key: OPENJPA-2194
URL: https://issues.apache.org/jira/browse/OPENJPA-2194
Project: OpenJPA
Issue Type: Bug
Reporter: Daniel Persson
Priority: Minor
Usually the transaction commit is submitting the update and therefor handling the switch to write mode. But in this case the switch never happens and exception is thrown.
em.getTransaction().begin();
Query q = em.createQuery("delete from users");
q.executeUpdate();
em.getTransaction().commit();

[jira] [Commented] (OPENJPA-2194) ReplicationDriver doesn't switch

Daniel Persson commented on OPENJPA-2194:
-----------------------------------------
After some trial and error I came up with
em.getTransaction().begin();
Query q = em.createQuery("delete from users");
OpenJPAEntityManager jem = OpenJPAPersistence.cast(em);
Connection c = (Connection) jem.getConnection();
c.setReadOnly(false);
q.executeUpdate();
c.setReadOnly(true);
em.getTransaction().commit();
Any better way to accomplice this?
