@ sheersh

Just my two cent too:

Also think about the vsam share levels. Parallel updates. I come across this, because you told that the same file is used in many jobs with DISP=SHR.

Second point: Is your site using any job scheduling system like OPC ore something else. In OPC (TWS) you could block access via a SpecialResource statment.
