Hi,

I'm using Spring Batch with hibernate3.2.3.
IBM DB2 V8.1
I got outOfMemory error when i executed batch process.
As per the Batch processing documentation i used session.clear for every 20 records. But i got two different types of exception
One is Found two representations of same collection:
other is R javax.transaction.TransactionRolledbackException: CORBA TRANSACTION_ROLLEDBACK 0x0 No;

Find the stack trace of all the exceptions

Hi All,

I have removed all the Set (one to many)mappings from hbm fiels and ran the batch. Session.Clear is working fine now.

What will be the impact if i remove these mappings? and what is the relation between this and clearing session?


Thanks,
Jay
