Operation

This section includes normal start-up and shutdown procedures for DOS/360 and for POWER. All of the jobs in the verify stage used these procedures for startup and shutdown.

The devinit Hercules commands in the following procedure include the CRLF option. This option should be omitted if you're using Hercules on a Linux system. If you omit CRLF when using a Windows platform, you'll have to fix the resulting file for viewing with Windows notepad using the following command:

type inputfile.txt | find /v "" > outputfile.txt

OPER01: Start / terminate DOS/360 and POWER for normal use

You should see the following on the telnet console, indicating a successful IPL of DOS/360 and a startup of the BG partition:

0I20I DOS IPL COMPLETE

BG 1C00A ATTN. 0 0C.

Stop BG, batch F1, assign SYSIN to the volume containing the JCL file, start devices, and then batch F2 and restart BG.

Note: In foreground partitions, "START" and "BATCH" are not synonyms. You must use the BATCH command to activate F1 and later F2.

POWER will start running. You'll be asked "FORMAT Q'S ?" If you have moved or changed the allocation of the POWER queue and data files, respond "D" to format queue and data files. Otherwise, you can just press return to warm-start POWER.

If you inadvertently "START" F1, you will be unable to assign SYSIN and you'll get the message "READ COMMAND NOT GIVEN." Type "CANCEL," return, and then STOP and return. Then you can try BATCH again. Here's an example on the console. Commands typed by me are in lower case, and responses are in upper case.

start f1

AR 1I60A READY FOR COMMUNICATIONS.

AR F1 assign sysin,x'191'

F1 1S01D INVALID STATEMENT.

F1 1C20D READ COMMAND NOT GIVEN.

F1 cancel

F1 0S02I JOB FG INIT. CANCELED DUE TO PROGRAM REQUEST

F1 0S10I PROGRAM FG INIT. COMPLETED

batch f1

AR 1I60A READY FOR COMMUNICATIONS.

AR F1

F1 1C10A PLEASE ASSIGN SYSRDR.

You want to see "PLEASE ASSIGN SYSRDR." That's your cue to assign SYSIN.

Note: If you shut down Hercules or DOS/360 without shutting down POWER first, you risk queue or data file corruption; format the queue and data file to correct this condition.

Now start the POWER II spooling reader and writers, restart BG under control of POWER, and issue the BATCH command to F2.

A job should run in each of BG and F2. These jobs load labels (F2) and complete partition assignments to printer, reader, and punch (BG & F2).

OPER90: End POWER and shut down DOS/360

POWER should be shut down prior to shutting down DOS/360, re-IPL'ing the machine, or quitting Hercules. Do the following

Yup, just E. If POWER elects not to shut down, "e kill" will do the trick. And if you're thinking, "gee, how many times was POWER II shut down by accident," well, I don't know. But it must have happened more than a few times because IBM removed the "e" abbreviation for the PEND command in POWER/VS.

When shutdown is complete, all three partitions will issue the message

1C10A PLEASE ASSIGN SYSRDR

Respond with "UNBATCH" to the F1 and F2 messages to terminate processing in those partitions.

Continue in the BG partition:

You may now use DOS/360 without POWER.

To shut down everything,
