Page of GC20-1806-9 As Updated April 1, 1981 by TNL GN25-0834 When CP commands are used to control the CMS batch virtual machine,
they must be preceded by the CMS CP command, because the implied CP function is disabled when batch initializes a job.
The following CMS commands are disabled under the Batch READCARD DISK LOAD The FILEDEF and ASSGN commands are also disabled for use in defining
the virtual card reader.
A more complete description regarding control of the CMS Batch
virtual machine is contained in the VK/370: CKS Guide. It
describes the user control cards and suggests control techniques as well
as how to control the batch machine using EXEC procedures.
The batch virtual machine spools output resulting from program OVO,...1,+;nn +n +},.o '''''''';'1'\+0lI0..- ... .... J..." .. h ... .; ....... .; ........ wu_ __ userid, with the submitting userid's distribution code, a spool filename
of CMSBATCH, and a spool filetype of JOB (unless a job name was
specified on the /JOB card).
The console output is always spooled. Therefore, if the console is
disconnected, the CMS console output is spooled to a file that is
printed following the user's program execution output at the real system
printer, with the submitting userid as distribution code, a spool
filename of BATCH, and a spool filetype of CONSOLE. If the CP TAG command has been used to identify spool files or to
direct these files to other virtual machines or remote work stations,
BATCH resets the spooling devices for the next job. PURGING, REORDERING, AND RESTARTING BATCH JOBS When required, the spooling operator can control the execution of batch
virtual machine jobs by purging, reordering, and restarting them; by the
same token, because all the closed printer files are queued for system
output under the submitting userid, the submitting user can change,
purge, or reorder these files prier to processing on the system printer.
To purge a job executing under the Batch Konitor, follow the
procedure below: Signal attention and enter the virtual machine environment.
2. Enter the HX (halt executionl immediate command.
3. Disconnect the virtual machine using the CP DISCONN command.
The HX command causes the Batch Facility to abnormally terminate.
This provides the user with an error message and a CP dump of the Batch
Facility virtual machine. The Batch Monitor then loads itself again and
starts the next job (if any).
To purge an individual input spool file that is not yet executing,
issue the CP PURGE command: PURGE READER spoolid

In the previous format, spoolid is the spool file number of the job
to be purged from the batch virtual machine's job queue. For example,
the statement: PURGE READER 123
would purge 123 from the batch virtual machine's job queue.
To reorder individual spool files in the Batch Facility's job queue,
use the CP ORDER command: ORDER READER spoolid1 spoolid2 ••• In this format, spoolid1 and spoolid2 is the assigned spool file
identification of the jobs to be reordered.
The operator can determine which jobs are in the queue by using the CP QUERY command: QUERY READER ALL
This QUERY command lists the filenames
in the batch virtual machine's job queue.
them, using the ORDER command. I STOPPING THE BATCH VIRTUAL MACHINE
and filetypes of all the jobs
The operator can then reorder When you want to stop batch virtual machine execution after completion
of the current job, you can issue the HB immediate command and press the
attention key or equivalent to cause an attention interruption at any
time during the job. This causes the batch virtual machine to be logged
out at job completion. When Batch Facility virtual machine execution is to be stopped
immediately, but current files must be saved, you can use the CP SPOOL command, in the form SPOOL READER HOLD, and issue the CP LOGOFF command.
The HOLD option causes CP to retain the virtual machine's current
card reader file, so that when the Batch Facility is logged on again,
execution resumes at the beginning of the held reader file.
If an emergency shutdown should occur, all jobs in the batch reader
and all spool files are saved. SUPPORT OF THE 3800 PRINTER AS A REAL VM/370 SPOOLING DEVICE Virtual machines can print spool files on the 3800 printer. However,
the use of more than one translate table for printing a given file notes
an exception. Once the user starts to print a spool file with specific
character sets, the entire file must be printed with these character
sets. At any time, the user may change the characteristics of a spool
file it actually starts printing.
