Right, if all you need are CP commands, then 'vmcp' and "AT" should do.

I'd be similarly reluctant to have Linux guests with extended
privileges, though it sounds like you're being selective about which
Linux guests are allowed to play here.

Following what Rob said, policy and all that, REXECD actually might work.
Isolate REXECD to a z/VM Guest LAN and allow selected Linux guests to
also access that guest LAN.

A guest LAN is substantially more secure than a physical LAN behind a
firewall. It's the only place I would use REXECD, but in that padded
cell I would have no qualms about using REXECD. You can then use Linux
'rexec' command to drive that worker CMS virtual machine.

Re: Remote exec script

Hi Rògerio,
   look at "wakeup"  module. 
It is an old module but it is available on zVM.

WAKEUP HELP : 
...The WAKEUP command waits for an event to occur, and then returns 
control 
your exec.  It can be used to wait for reader files, messages, timer eve 
etc.  The return code tells your exec what event caused wakeup to end... 

It has been referenced on Redbook  Virtualization Cookbook for z/VM 6.3. 
i.e.  pag.124
You need a virtual machine running wakeup on each node  customized as you 
need.


Cordiali saluti  / Best regards
 
Marco Bosisio

If you have a Linux guest on one of the members, you can issue some CP
commands through the AT command with 'vmcp' though I personally would be
reluctant to have Linux guests with extended privileges.

For anything beyond that you'd probably have to set up a suitable
infrastructure with a worker machine on each member. That can be done with
an existing product like IBM Wave, IBM Operations Manager, or some
creativity and elbow grease. Unless 'rexecd' fits your policy.
