RE: Anonymous keys
Hi, I have some doubts though: 1. In the access attribute for an reference field (as given below in repository_user.xml) which is the best option? a. read only b. read write c. anonymous 2. When I use access=anonymous, I have to retrieve the references before I store the object. This is causing problem when I run the use case for 35 concurrent users. Any suggestions? 3. When I use access = read, I add the attributes in the Java bean. But when I run the application it is giving an error "Cannot Insert Null into a Not Null column" OJB version I use is 1.0.

Clear cache issue!
Hi All, I'm using the following code: QueryByCriteria queryByCriteria = new QueryByCriteria(RefInfoData.class, criteria, true); broker.clearCache(); Collection refInfo = (Collection) broker.getCollectionByQuery(queryByCriteria); For the class 'RefInfoData' we have set the cache level as default implementation. When we use the method "broker.clearCache()" we are facing performance issues. But when we don't clear cache there is dirty read. We are maintaining the cache for reference tables. Is there a way to clear cache for the specific object instead of whole cache?

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();
}

Hi,
After the insert transaction is committed, I try to read the

Actually it's like this:
In for loop
I check to see if there is
Record for a particular
combination (let's say record for name="A").
< TRANSACTION 2 BEGIN>
If the record does not
exist I insert the record
(with name="A").
< TRANSACTION 2 END>
When the I come across same
combination and check if r record
exists (with name="A"),
A null record is returned.
< TRANSACTION 1 END>

Could you give us more details.

Did the second broker instance try to read the record before the first

Problem in retrieving data
Hi, I'm facing a problem. The problem description is as follows: I insert a record (if the record does not exists for a particular combination) into a table in a (broker) transaction and try to access the same record in a different (broker) transaction. Though the record gets inserted in the physical database, OJB is not retrieving the record. When I stop the server and run the application again the data is retrieved. The sequence: INSERT > RETREIVE data is not working. RETREIVE data is working Please Help!!!
