Hello, what can I do to prevent Out of Memory-Errors when working on large datasets? I tried to do tx.commit(); tx.begin(); after doing part of the (big) job, but I didn't succeed. Do I have to empty the Cache explicitly? What is recommended? I create the objects that cause the error in my

Strange error...

Hello, Could please anyone help me in finding the reason for the following error: It occurs when creating a bunch of new objects ... [org.apache.ojb.broker.accesslayer.JdbcAccessImpl] ERROR: SQLException during the execution of the insert (for a org.apache.ojb.odmg.collections.DListEntry_2):

Re: Strange error...

Is it possible that the reason is a change in my datamodel: I added an additional ojb collection, backed by a DList. My old objects in the db don't have this dlist. I assume, ojb tries to load the dlist and doesn't find it. Am I right? How can I fix this?? Thanks a lot. -Gunnar

Rollback not working

When trying code i catch exception and do a tx.abort() when an error occurs. But when the error is caused by an SQLException during tx.commit() all changes done are written to the database... this is a real problem for me. Shouldn't the db-commit be all or nothing (rc5, postgres). -Gunnar

questions about tx.lock() and a feature request

Hello, 1.) I was just trying to update data with odmg and found that using implicit locking is quite tricky because it seems to result in locking the same Objects multiple times eventually. Is this assumption correct? If so, is it a good advice to turn implicit locking off with

Re: ODMG update

Hi! Hi Gunnar, I will try to write a test case for your problem. By the way, does your test pass when you switch back to old DList implementation class in OJB.properties? I think I found the problems in my code. It was caused by implicit locking. All worked well when I turned implicit

I know this has been asked before but I couldn't find a satisfying answer: What do I have to do to use CLOBs in PostgreSQL? Is the patched driver enough? Do I have to follow the the proposal on db.apache for postgresql/CLOB (It is sometimes referred to as outdated). Thanks a lot, -Gunnar
