Page of GC20-1806-9 As Updated April 1, 1981 by TNL GN25-0834 A feature that closes CP spool files is available for OS/VS1. When the VM/VS Handshaking feature is active, VS1 closes the CP spool files
by issuing the CP CLOSE command when the VS1 Job output from its DSD, terminator, and output writer is completed. Once output files are
closed, they can be processed by V!/370 without operator intervention.
without the VM/VS Handshaking feature, CP spool files are not sent to
the real printer or punch until the virtual machine operator intervenes.
Using the eMS Batch Facility The Batch Facility is a V8/370 programming facility that runs under CMS. It allows a VM/370 user to run jobs in batch mode by sending jobs from
either his own virtual machine or the real card reader to a virtual
machine dedicated to running batch jobs under the Batch Facility. This
dedicated machine is aenerallv set uo at a terminal in the
installation's computer room and is controlied by the system operator.
The Batch Facility virtual machine runs continuously, executing all
jobs spooled to its virtual card reader from other virtual machines or
from the real card reader. The batch operator need pay no attention to
the batch machine once he has started, and disconnected it. I STARTING THE BATCH VIRTUAL MACHINE The system operator starts the batch virtual machine by logging on with
a batch userid and loading CMS using the CP IPL command.
Every installation in which the CMS batch facility is available should
establish one or more common user ids for the Batch Monitor virtual
machine. Users can then spool their files for execution to the card
reader for that batch userid.
It is the operator's responsibility to log on the V"/370 system using
the batch userid that has been established for his installation.
The userid established for the batch facility virtual machine must
have a read/write work disk in its directory at virtual address 195.
The 195 disk is erased when it is accessed as the A-disk at the
beginning of each job.

The batch facility virtual machine is invoked by the Qatch operator when
he issues the CP IPL command with PAR! BATCH or CP IPL followed by the C!SBATCH command. The latter method follows:
ipl cms CMS mm/dd/yy WED 17.58.48
cmsbatch Y/S (19E) R/O.
THE FOLLOWING NAMES ARE UNDEFINED: BATEXIT1 BATEXIT2 R; T=O.14/0.39 08:47:40 WAITING FOR THE READER
The operator may now disconnect the batch machine terminal, if he
wishes, using the CP DISCONN command. The Batch Facility will IPt ·itself after each job is executed.
All v irtual machine (CMS) console output is a utomatically spooled to
a file to be printed after the program output at the real system
printer. All commands entered through the virtual reader are displayed
on the console to allow them to appear in the console output file. If
the batch terminal is disconnected, only CP and batch initialization messages are displayed at the terminal.

CONTROLLING THE BATCH FACILITY The batch facility permits CP and CMS commands to be issued from the
batch job stream submitted by the user.
The following CP commands, and only these commands, control the batch
virtual machine: • CHANGE - May not be used to change the virtual card reader. • CLOSE - Hay not be. used to change the virtual card rE!ader. • DETACH - May not be used to change the virtual spool devices or the
system, IPL, or 195 disks. • DUMP • DISPLAY • LINK -A maximum of 10 links may be in effect at anyone time;
and, LINK must be used as shown in the following format: CP LINK userid vaddr vaddr mode password I • HSG I = QUERY ,. SET , I • SPOOL I • STORE I • TAG
- Only the following SET command operands are allowed under eMS batch: ABBREV DOS I!PEX LDRTBLS NONSHARE RDY!SG SYSNA!E UPSI - May not be used to change the virtual card reader.
