I have a series of scripts running in parallel as a nohup on an AIX server hosting oracle 10g. These scripts are written by somebody else and are meant to be executed concurrent
I ran into this issue as well. I don't know the technical details of what was actually happening. However, in my situation, the root cause was that there was cascading deletes setup in the Oracle database and my JPA/Hibernate code was also trying to do the cascading delete calls. So my advice is to make sure that you know exactly what is happening.
