This book is for those persons responsible
for the operation and administration of a VM/370 system.
This operator's guide describes some of
the hardware of the system/370 as well as
some user virtual machine requirements.
The CMS Batch Facility is the only batch
operation discussed in this publication.
For general information on how to run batch
jobs in VM/370 virtual machines (other than
CMS), refer to the !ir1yal Order No. GC20-1821. To manage V8/370 resources effectively,
a system operator should be familiar with
the operation and hardware requirements of System/370 input/output devices and should
know the broad concepts of computer
operations. In addition, the system operator should be familiar with the use
and capability of the Interactive problem
Control System component of Details of this major component are
contained in the IBM virtual Machine £ontrQ! Eysty (!R£E) Order No.
GC20-1823.
If your installation uses the VM/370 Remote Spooling Communications Subsystem
(RSCS), the system operator is generally
the operator of the RSCS virtual machine as
well as of the real machine at the
installation. For details on how to operate
the RSCS virtual machine, refer to the IBM !!rtual Q§er's Order No. GC20-1816. Preface
There are five sections in this
publication. The first section discusses
the Operational control of VM/370 under
normal and adverse conditions. The next four are the "how-to-do-it" sections. Wherever possible, subject matter adheres
to an alphabetic arrangement. The appendix
contains a summary of operator and user
commands.
