Remarks
Integer values provide fine-grained control over deadlock priority. Priority values specify that the current session will be the deadlock victim if other sessions in the deadlock chain are running at a higher deadlock priority value, but will not be the deadlock victim if the other sessions are running at a deadlock priority value lower than the value of the current session. It also specifies that the current session is eligible to be the deadlock victim if another session is running with a deadlock priority value that is the same as the current session. LOW maps to -5, NORMAL to 0, and HIGH to 5.
