Oracle Database Discussions

Hi

I have a customer having a long running batch job (approx 6 hrs), recently we experienced performance issue where the job now taking >12 hrs. The database server is crawling. Looking at the alert.log showing some deadlock,
The batch job are in fact many parallel child batch job that running at the same time, that would have explain the deadlock.

Thus, i just wondering any possibility that due to deadlock, can cause the whole server to be crawling, even connect to the database using toad is also getting slow or doing ls -lrt..

Thanks
