Use of the VM:Tape command exit provides a means to automagically swap the

automatic. VM:Backup tapes are still twinned to external 3590 ma

Yes, Thanks Alan. In the TCPIP PROFILE I did specify 16K but I received
an error so I changed it to 1500 which I new would get around the error.
When I did the NETSTAT displays I saw a MFS of 4096 and MTU of 32768. So
I guess the question is why did I get the error in the TCPIP PROFILE

Can't do that, unless you can guarantee that the tapes at the remote site
are longer than the local copy (which would be unlikely). When the backup
runs, writing to a given pair of tapes ends when the first one hits EOT.
You would also need to a complete copy of the tapes, labels and all,
because
I think in the case of having to run 2 backups jobs I would run one
backup job and then run a utility job to copy the 1st set of tapes to
the remote set of tapes.

Hello list,
I'd like to replace the MONWRITE service we use now with a way to only

Even though my customer's MVS systems are becoming short of UCB's, each

though the VM and MVS support groups are (or I should say were) different,
this uniqueness is maintained across VM and MVS systems.
