ORA-00060: deadlock detected while waiting for resource

Question

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

Answer 1

I was testing a function that had multiple UPDATE statements within IF-ELSE blocks.

I was testing all possible paths, so I reset the tables to their previous values with 'manual' UPDATE statements each time before running the function again.

I noticed that the issue would happen just after those UPDATE statements;

I added a COMMIT; after the UPDATE statement I used to reset the tables and that solved the problem.

So, caution, the problem was not the function itself...
