GALAXY.DOC -- Changes from V2 to V3
September 1978
1.0 SUMMARY
GALAXY is the Batch and Spooling subsystem for the DECsystem-10 and
DECSYSTEM-20. GALAXY comprises all the software (excluding operating
systems software) necessary to do batch processing and input and
output spooling and all queue management and task scheduling required
for those functions.
GALAXY Release 3A consists of the following programs:
Program Version What it does
------- ------- ------------
QUASAR 3 Central queue manager, task scheduler, and
GALAXY system controller.
BATCON 103 Batch job processor.
LPTSPL 103 Lineprinter output spooler (unspooler).
SPRINT 103 Card reader input stacker/spooler.
QUENCH 3 Timesharing users' interface to the GALAXY
system.
QMANGR 103 Interface module for FOROTS, BASIC, etc.
Release 3A has two primary goals:
1. Support USAGE file accounting for printer and reader
spooling.
2. Provide some hooks for the DN64 project.
In addition a number of maintainance edits were merged in to
development versions which resolved a number of problems.
1.1 Monitor Dependence
Release 3A of GALAXY will run under the following monitors:
1. TOPS20 Release 3A and later
GAL3.DOC Page 3
2.0 EXTERNAL CHANGES
There are two major external changes in Release 3A of the GALAXY
system. The first is that the queue manipulation commands (PRINT,
SUBMIT etc.) are now processed by the EXEC. This provides full
compatibility with the TOPS20 command language as well as a
significant improvement in response time for these commands. A
complete description is provided in the EXEC DOC file. The QUENCH
program is still being shipped with GALAXY primarily for compatibility
purposes. The EXEC also has the
@SET OLD-QUEUE-COMMANDS
@SET NEW-QUEUE-COMMANDS
commands added. Typing the first of the above commands will cause the
PRINT and SUBMIT commands to work as in previous versions.
The other major external change in Release 3A is the addition of the
/ACCOUNT switch on the $JOB card. The format of this switch is:
/ACCOUNT:account-string
During $JOB card processing, SPRINT will verify the user's account
specification. If a /ACCOUNT switch is not found on the $JOB card,
SPRINT will look for a default account for the directory
PS:<user-name>. If there is no default account for the directory, the
account under which SPRINT itself is running will be used. The last
option is included in order to let installations phase into using
account strings. Initially, the system administrator can cause SPRINT
to be logged-in under a universally allowed account and after a
specific date cause SPRINT to be logged in under a universally illegal
account.
In all cases, SPRINT will verify the account string it decides to use
(from any of the three sources described above) and if the
verification fails will produce the following error and abort the job:
?SPTIAS Illegal Account Specified
One additional implication of this change to SPRINT is that the
specified account is now passed on to BATCON and is used to log the
batch job in.

3.0 KNOWN BUGS AND DEFICIENCIES
1. Any file created by SPRINT or BATCON is created with the
account string of SPRINT or BATCON (e.g. LOG files from
BATCON, or $CREATE in SPRINT).
2. The message %Problem on device PCDR0: is typed on the CTY
whenever the hopper goes empty on the card-reader. It can be
ignored.
3. There is no mechanism for putting parameters (e.g. /COPIES)
on spooled files.
4. If a batch job does a "@OPERATOR $" (the dollar sign is
default) and the batch job then enables itself (or was
enabled already) then any time the EXEC prompts the job (i.e.
with a $) the job is put into OPERATOR wait.
5. There are two problems which will causes a job to get the
error message:
?SPTIDP Incorrect Directory or Password
a) If the previous job forgets a $EOJ card
b) If there is no space following the user name on the $JOB
card
NOTE
There are a number of valid reasons for
receiving this message. The two most
common are a misspelled user name or
password and specifying a files-only
directory instead of a user name.
6. If a $JOB card contains a /JOBNAME switch which does not
include a value (e.g. $JOB user /JOBNAME) SPRINT will crash
with the error message
?SPTCCC Can't create CTL or LOG File - File Not Found
?SPTCCC Can't create CTL or LOG File - File Not Found
?PA1050: ERROR IN
