Hi All,
I'm using:
1. OJB version 1.0
2. The block looks like:
broker.beginTransaction();
broker.store(Object);
broker.commitTransaction();
Regards,
Vagula

Hi Vagula
It is difficult to answer if there is not code sequence and properties.
Your problem can be in some OJB settings but it is also possible
That you have a kind of anti pattern. For example same reference to
The data object in both threads.
We work with over 1000 concurrent threads on the same data object and have
no problem. Hear some example:
1. We work with ojb version 1.04
2. we work not with a cash (the cash in version rc1 was corrupt), but
perhaps it works now.
2. each call looks like:
Try{
broker = PersistenceBrokerFactory.defaultPersistenceBroker();
// in J2EE do not handle transctions
broker.store(yourObject);
}finaly{
if (broker != null && ! broker.isClosed())
broker.close();
}

Betreff: RE: Concurrent Users-Please Help!
Hi All,
I'm using PB API. When concurrent threads are running on a
particular object, the data
gets corrupted.
Let say Thread1 sends data 1,2,3,4
Thread2 sends data 5,6,7,8
In the DB data stored is 1,2,5,6.
How can I solve this issue?
Please Help!! Urgently need solution!!
Thanks in Advance!
Regards,
Vagula

Hi,
Yes I need info about concurrent connections. What are the settings
to be in OJB.properties?
Thanks!

Hi Vagula,
Would you explain more your idea? If you are talking about concurrent
connections to the database, OJB has database connection pool, which can
be configured in the OJB.properties.
Best Regards,
Antonio Gallardo.
