The issues listed in the original post plus those suggested by others are
potentially *very* serious. I have to ask what benefits are expected that would
justify the risk. Surely sysplex overhead alone would not be worth damaging a
catalog for example. Whose idea is this?

Something we sometimes do is; Transfer large files with FTP from z/OS LPAR to
another LPAR (or any host). The FTP program gives a nice report per certain
amount of bytes transfered or time interval. (Either one of them, can't exactly

ARM is a much newer facility, with a different purpose. Automatic step restart
goes all the way back to OS/360; see the RD=R parameters on JOB and EXEC.

manual restart. That applies to both checkpoint and step

No, temp and VIO don't go away when the system crashes. If you have automatic
step restart and don't do a CVIO, then the restarted job gets the previously
allocated VIO data sets.

I believe he was referring to checkpoint restarts , years ago we had many long
running processes that used checkpoint restart, if standalone was needed and
these jobs had to be cancelled we did not perform CLPA.
I believe this is still an issue for checkpoint restarts?

This is a good point. For PDS what would be ideal is that you checkout a
member and when saving it perform a diff / merge (while holding the ENQ) for a
short period of time. Not a long hold that will eventually cause issues with
ENQs that were requested and not released in a timely manner.
