HI,
Our JBOSS EJB3 container (4.0.3SP1) is hanging in a few minutes followed by a
timeout, when I try to persist and flush a large number of objects (actually
only about 1500 objects) objects in one transaction. The overall exception is
Transaction is not active: tx=TransactionImpl:XidImpl[FormatId=257,
GlobalId=WMLI011810/744, BranchQual=, localId=744]
In a statefull session bean an object A is created. Afterwards about 1000
entries of another object B are added to a collection in object A - these
B-objects needs to be persisted when object A is persisted. The operation
em.persist(A) takes about one minute to complete - that's ok in this situation.
So far no problems...
Now, when the sessionbean is doing a em.flush() or returning control back to
the container (after last statement in the method is succefully complated), the
container is hanging for about 3 minutes before a timeout is thrown. The JBOSS
java.exe process is using 100% cpu power.
Why should is take so long time and so many resources to flush/commit only a
few thousand objects?
If I'm reducing the B objects to about 50 og 100 then anything works nice.
Isn't JBOSS scaled for large transactions?
Can anyone help us with this problem?
