Using "/DD:" when running BPXBATCH? (the shell runs in a separate address space)
If you use a tool that runs the shell script in the same address space, then you can use either a DD or a DSN (dynamic allocation in the same address space won't conflict with the initiator ENQ since it is the same address space).
