When the Initiator frees a dataset and no subsequent step has a DD for it, the
Initiator does a DEQ. If there is a subsequent dynamic allocation, then the
Initiator does a new ENQ; there's always a possibility that some other job will
get there first.

An application can generally deallocate any dataset that it is not using. If
you want to deallocate a dataset from some other address space, drop that

Yes, agreed, that's possible. There can also be slight differences after
the HMC receives a code update.

As soon as you start production at the DR site, you need to start
replication to your next site (production or third site).
If you have a clean shutdown and the mirroring software supports it,
you might be able to swap primary and secondary to avoid having to
copy the volumes.

AFAIK either the initiator does the ENQ (when there is a DD statement) OR
dynamic allocation does the ENQ (when the code does a DYNALLOC). The same
applies to the DEQ.
To avoid deadlocks the initiator does all ENQs ahead before starting the job.
DYNALLOC returns "not available" when another tas
I wonder: can I deallocate a dataset with DYNALLOC, that has been allocated by
the initiator because there is a DD statement?

Where does the term 'reference count' come from? If the initiator deallocates a
dataset, either because of step-end or because of FREE with CLOSE, it dequeues
the dataset if no subsequent step needs the dataset anymore.

It all is a matter of the right contracts, if your company can afford the costs
of course.
As to Mikes answer: you do mirror data constantly from the first to the second
datacenter, don't you? Why would you move to the second center if
With a proper GDPS implementation, you don't even need a clean shutdown. A
