RE: migration from 32 bit to 64 bit problem

The explain plan in the second one is using a cartesian merge.

I am trying to use hints in the views to no avail, see hybernate creates the select.

The wierd thing is that all the data, etc is the same. The only difference is the database 32/64 bit.

I tried setting the _complex view parameter and bounced the database and this didn't help.

No one else is using this database but the this user.

Sorry if this has been explored, but it sounds like the difference in the plans is the problem. Can you elaborate on WHAT is different about the plans?

Is something else hogging temp?
