Vishal updated OPENJPA-2834:
----------------------------
Description:
Hi Team
We are facing Performance issue with OpenJPA-3.1.1 when we deploy our
application in EAP 7.3 Server but similar issue is not replicated with
Wildfly-10.1.0 server with same version.
Below is reply from RED-HAT Team memeber we have received
{color:#ff8b00}With the scope of WFLY-7075 (see [1]) the
'TransactionScopedEntityManager' implementation got updated to throw an error
if a jta transaction already has an UNSYNCHRONIZED persistence context and a
SYNCHRONIZED persistence context is requested. For this the implementation is
using the 'EntityManagerFactory', see: ~~~ private static void
testForMixedSynchronizationTypes(EntityManagerFactory emf, EntityManager
entityManagerFromJTA, String scopedPuName, final SynchronizationType
targetSynchronizationType, Map targetProperties) \{ boolean
skipMixedSyncTypeChecking =
Configuration.skipMixedSynchronizationTypeCheck(emf, targetProperties); //
extension to allow skipping of check based on properties of target entity
manager boolean allowJoinedUnsyncPersistenceContext =
Configuration.allowJoinedUnsyncPersistenceContext(emf, targetProperties); //
extension to allow joined unsync persistence context to be treated as sync
persistence context ... } ~~~ Printing the stack in 'EntityManagerFactoryImpl.'
shows: 11698 ragedesign INFO [default task-1] openjpa.Runtime -
org.apache.openjpa.persistence.EntityManagerFactoryImpl.getProperties(EntityManagerFactoryImpl.java:125)
11698 ragedesign INFO [default task-1] openjpa.Runtime -
org.jboss.as.jpa.config.Configuration.skipMixedSynchronizationTypeCheck(Configuration.java:345)
So, the code above calls 'EntityManagerFactoryImpl.getProperties(...)' from
OpenJPA, see: ~~~ @Override public Map<String,Object> getProperties() \{
Map<String,Object> props = _factory.getProperties(); // convert to user
readable values props.putAll(createEntityManager().getProperties()); return
props; } ~~~ As you can see this code is creating a new 'EntityManager'
(createEntityManager()) on every invocation just to get the Properties. As
mentioned in the beginning to resolve the issue for JBoss EAP 7.3 and Open JPA,
you would need to fix this in Open JPA {color}
{color:#172b4d}They have also shared link for Jira of JBOSS
[https://issues.redhat.com/browse/WFLY-7075]{color}
I am attaching Project and logs for reference.
