Default DTS jobs create Locking Problems - 10-05-2004 , 07:35 PM






We have a dozen or so DTS jobs that run on our SQL Server. They run
independently and sometimes a particular combination occurs that causes a
deadlock. Our biggest problem is that we don't know why SQL Server is
locking the tables at all. In some cases we're doing a data driven query and
it locks the source tables. Can someone point me to information concerning
how to control or at least predict the locking mechanism? Thanks.

BOL has a good section on locking but Kalen Delaney also wrote an eBook
about blocking which extremely good.
