Re: MTS under VM/ESA

 

Adding in:


QUERY

CPUID = aabbbbbbccccdddd

Where:

aabbbbbbccccdddd
is the 16-digit processor identification associated with the
virtual machine.

aa is the version code; these two digits are forced to X'FF' to
identify that the virtual machine is running under VM/370.

bbbbbb is the processor identification number; this field contains
six hexadecimal digits. This is the only part of the CPUID
that can be modified by means of the SET CPUID command or set
by the VM/370 directory's OPTION contrel statement.

cccc is the model number; this field contains a leftmost digit of 0
followed by three digits of the wodel number (0-9;. This
field defaults to the model number of the real machine.

dddd is the machine check extended logout; this field is forced to
X'OOOO' since CP does not reflect machine checks back to the
virtual machine.

If I remember correctly you can use the STIDP store processor ID instruction and the info you get back (I think it's high values at the end X'FF' means it's running under VM.

Will it implement handshaking? That is, will MTS automatically close
the spooled printer files so it will be printed by the real printer

No. It has no special support for VM. It treats VM like a funny sort
of real machine.
Most operating systems are largely, but not completely, unaware that they are running under a virtual machine such as VM, and rightly so. BUT... in a few specific places they, IMHO, do need to be aware of it. Closing their spooled printers between jobs is one such place. AFAIK all IBM operating systems do this, and IMHO so should MTS too, if/when it's run under VM.
