BATCH PROCESSING

CHAPTER 1
INTRODUCTION TO BATCH PROCESSING

1.1

INTRODUCTION

RSX supports an extensive set of batch-processing functions.
The
Batch Processor (BATCH) is a specialized program that has many of the
characteristics of an I/O handler. RSX allows the use of BATCH as an
extension of on-line task development (TDV) under MULTIACCESS or as a
total system environment.
BATCH offers fast, efficient data-processing by enabling an operator
to stack multiple jobs to be executed in sequence.
BATCH is
file-oriented, device-independent, and suitable for use in both
card-oriented
environments
and
terminal job-entry/remote-access
operations.
It has been designed to work well in small configurations
without sacrificing the high throughput and short turnaround that
large systems require.
Some BATCH commands allow each job to invoke all TDV functions. Other
BATCH commands also provide various control and message logging
functions.
Job accounting and account summaries in the Batch System are handled
by the TDV functions ACI and ACD. Control lines are listed on the
line printer and, for additional backup, an operator
log
is
maintained. BATCH also provides:
Job header and trailer pages
Full FORTRAN, MACRO and loader facilities, including overlays
System protection from undebugged jobs
Convenient operator communication and control
SLIP, a sophisticated file editing and updating program with
search capabilities (described in Part VII of this manual)

SAMPLE BATCH SEQUENCE

Figure 1-1 illustrates a sample set of commands read during a
batch-processing operation.
The figure shows the commands in card
format, but they could also have entered (into a disk file)
from a
terminal.

$BTK calls the Basic Task Builder to build a task with the same name
as the binary file that serves as input to BTK. BTK builds the task
to run in a partition named TDV, gives the task a default priority of
400, and builds the task to run in user and page modes. The task
cannot contain overlays.
(If nonstandard options are desired,
the
user must call TKB, a more flexible version of the Task Builder.)
$CON stores the task on a user disk.

XVM/RSX V1B

$XQT executes it from that disk.

VIII-1-2

September 1976

INTRODUCTION TO BATCH PROCESSING
When the task is running, it is capable of reading formatted data
(lOPS ASCII)
from the BATCH input device.
The data section is
terminated by $EOF (end-of-file). After the task completes execution,
it exits. Should the task fail to exit, the operator can force it to
do so by using the OPR MCR Function task (see Chapter 4).
$END indicates the end of the job file.

INVOKING AND USING BATCH

2.1

JOB FILE SUBMISSION

Before BATCH is invoked, job files must be submitted to it by means of
the QJOB directive, which can be issued by:
TDV function QUEUE
BATCH command $QUEUE, which calls TDV function QUEUE
User-written programs in FORTRAN or MACRO
In each case, the QJOB directive supplies the following information:
Name of the job file (if the device is file oriented)
LUN from which the file is to come
Maximum time that the job can run
Job class
Whether the operator is required
Whether sequencing is required
Whether the file is to be deleted after execution
Time of job submission (supplied by the system)
Memory use
Use of hold mode
Whether this is a priority job
Login device, unit and UFD

2.2

INVOKING BATCH PROCESSING

BATCH is invoked by the operator using the MeR command:
MCR>OPR BATCH
BATCH initializes itself and waits.
Following an OPR GO command,
BATCH scans the job file request list, selects the job file that
XVM/RSX VIB

VIII-2-1

September 1976

INVOKING AND USING BATCH
passes certain logical tests and has the highest priority, and begins
processing that job file.
After that job file has been processed,
another one is usually selected. The operator can use special aPR
commands to supervise BATCH operations.
Because BATCH loads and
waits, the aPR GO command is needed before the first
job file
is
executed.

2.3

CONTROL LINES

Only control lines (lines beginning with $)
have meaning to BATCH.
Other lines,
which contain data, FORTRAN source text or other text,
are passed on to the tasks called by control lines.
Control lines
fall into two groups:

TERMINATING BATCH PROCESSING

BATCH continues to run jobs until the operator exits with an OPR EXIT
command.
This command causes BATCH to exit after completing the
current iob file.
If BATCH finishes processing all waiting job files,
it remains idle until more job files are submitted or until the
operator exits.

CHAPTER 3
SPECIAL BATCH COMMANDS

3.1

$JOB: BEGIN A JOB

Each job must begin with a $JOB line. BATCH ignores all lines until
it recognizes a $JOB line, but the TDV function QUEUE requires that
the first line of a job file be a $JOB line.
$JOB lines have the format:
Form:

$JOB nn[T=time] [DEL] [HLD] [C=class]
fM=memory] [SEQ] [OPR] [FRC] [UFD=Rmn]

Where:

nn is a user account number in the decimal
range I to 99
time is an integer in the decimal
range 1 to 1023, representing the
maximum number of minutes that the
job can run
class is an integer in the decimal range
o to 7
memory is an integer in the decimal range
1 to 128, representing memory use
(in K)
m is F, K or P, representing the type
of disk:RF DECdisk, RK cartridge
disk, or RP disk pack, respectively
n is the unit number of the disk
ufd is the name of the user file directory

Example:

$JOB 15 UFD= SEQ

$JOB line options are the same as those for the QUEUE command.
A job file should contain only a single job; however, multiple jobs
can be included in a single job file by beginning each job with a $JOB
line. The second and subsequent $JOB lines terminate the previous job
and begin a new job. All jobs in the same job file are executed using
the same set of option flags.
Only the first occurrence of a
particular option is recognized.
Subsequent occurrences of an option
are ignored.
BATCH does not process $JOB line options. The $JOB line is passed to
a Job Startup Processor
(JOB ••• ) that determines the user account
number. All options in the $JOB line are processed by the TDV
function QUEUE when it queues the job request.
(Refer to Part VII of
this manual for a description of QUEUE.) QUEUE scans the job file,
XVM/RSX VIB

VIII-3-1

September 1976

SPECIAL BATCH COMMANDS
recognizes $JOB lines,
processes any options found and encodes the
option information into the QJOB directive.
On recognizing a $JOB line, BATCH first terminates the previous
iob,
if any.
BATCH then initiates the new job and invokes JOB ....
This
task determines the user account number from the $JOB line,
prints a
job header page and logs the start of a new job on the operator
console.
The user account number is saved in the BATCH accounting
file for use by the BATCH Job Termination Processor (END ... ).
The job time limit ($JOB T=time option) restricts the length of
time
that a job file can run.
When that amount of time has been used, the
job is terminated, unless the system manager grants an extension.
Job
execution time
is real time (clock time) less any time spent on the
following functions:
1.

Printing job header and trailer pages.

2.

Waiting for the operation to proceed from a $PAUSE.

OPERATOR CONSOLE

The operator console (operator log), is usually assigned during BATCH
operations to the same hard-copy terminal as the device for MCR
command input. The operator invokes BATCH with the command:
MCR)OPR BATCH
When this is done, a line feed is printed on the operator console
BATCH enters the wait state (see Table 4-l).

and

As BATCH begins to process a job, it prints a message on the console.
When BATCH finishes processing a job, it prints another message on the
console. These messages are printed by the tasks JOB .•.• and END •.. ,
respectively.
The operator also uses the console for the special
operator (OPR) commands described in the following sections.

Where:

TF represents the time factor
WF represents the wait factor
CF represents the class factor

Section 6.3

explains

Instead of setting the parameters in this way,
the operator can
respond to the asterisk by entering the name of an existing file. A
scheduling file consists of one line of scheduling parameters in the
format previously given.
For example, if the operator types:
*NOON
BATCH looks up NOON SCH.

If the file is not there, it prints:

If the file is there, it is printed and the parameters

In this way, the OPR SCHEDULE command can enter parameters from a
scheduling file, but it cannot create such a file.
This must be done
by ordinary editing. The scheduling file can be named for the time of
day that it will be used.
Instead of using the OPR SCHEDULE command, the operator can use a
combination of OPR HOLD and FORCE commands to request that each task
run in turn. This, however, is much less convenient.

ORGANIZATION OF THE ACCOUNT FILE

BATCH maintains an account file as a disk-resident data set named
"USERS RSX".
It maintains both current and historical information on
the use of the RSX system. The file contains the following general
information:
Current user account number
Account period starting date and time
For each account, it also records the number of jobs run and the total
time used.
The file provides space for 100 accounts. Account numbers 1 to 99 are
reserved for users.
Account 100 is used by all runs processed with
incorrect $JOB lines.
Incorrect $JOB information prevents
the
operator log from keeping track of who is using the machine.
Therefore, whenever a job account cannot be determined,
the job is
assigned to account 100 and a warning message is printed on the
operator console.
Account numbers are most meaningful when
A block of numbers can be assigned

The account file is updated by JOB ••• and END ..•.
In addition,
two
TDV commands are provided to facilitate account file management:
ACI
and ACD.
ACI permits account file creation,
initialization and
modification.
ACI records the date and time in the account file when
the file is initialized
(at the start of the current accounting
period).
ACD prints the contents of the account file, showing all
accounts that have been used.
Because ACD does not modify the account
file, the file can be printed as often as desired.

ACI: INITIALIZE THE ACCOUNT FILE

The ACI TDV Function task initializes the account file for
batch
processing.
It permits the system manager to create an account file,
to edit the account file, or to reset all usage data to zero at the
beginning of a new accounting period. The current time and date are
set according to the system.
It is advisable to verify that they are
correct or to change these numbers using the ETI MCR Function task.
ACI may be used only when BATCH is not running, otherwise, errors can
result from simultaneous account file updates.
The ACI TDV command has the format:
Form:

ACIV

Example:

TDV>ACI

ACI responds with a request for a password:
ENTER PASSWORD:
The correct password in the system as distributed is RSX.
The system
manager should change this password to suit the processing environment
and to guarantee the integrity of the accounting data.
This change
can be made in the source code of ACI, which is written in FORTRAN.
After the password is entered, ACI overprints it and checks
its
validity. An invalid password causes ACI to exit.
If the password is
correct, ACI continues with the questions that follow.
If no account file currently exists, ACI asks whether

be

CREATE NEW ACCOUNTING FILE (YES/NO)?
A reply of .INO· I causes ACI to exi t wi th no action taken. A reply of
"YES" causes the account file to be created and initialized.

If an account file already exists, ACI asks whether
it should

ACD: DISPLAY THE ACCOUNT FILE

The ACD TDV Function task permits the system manager to list the

The system manager can then identify the users of the
batch system and the amount of time used by each. ACD overcomes the
need for detailed checking of operator loqs.
The ACD summary listing
also allows the manager to evaluate the impact of any system changes.
Listings can be requested as often as desired, because they do not

The names in parentheses are the task names of the respective
components.
The following sections provide descriptions of the
individual components and how they interact.

6.1.1

QUEUE TDV Function Task (QUE ••• )

The QUEUE command is the main user interface with the Batch System,
providing
a
convenient
mechanism for submitting jobs.
QUEUE
determines all of the flags and values that affect job scheduling,
including such items as run time limit, priority class, memory
requirements and operator requirements.
This information is obtained
from the QUEUE command line and by scanning the job file for $JOB
lines.
For each parameter, the first value found is used.
In this
way,
the command line overrides $JOB lines,
the first $JOB line
overrides the second, and so on. The job information is encoded into
a QJOB directive CPB and the job is submitted to the system.
QUE •.• processes the entire $JOB line, except for
the user account
number.
BATCH does no $JOB processinq at all.
For this reason, when
the NCK option is used with QUEUE,
all scheduling options on $JOB
lines are ignored.

XVM/RSX VIE

BATCH OPERATIONS
6.1.2

Executive QJOB Directive

The QJOB directive adds a node to the job queue and copies the CPB
information into it.
I/O device specifications are translated from a
LUN number to a device name, unit number and UFD name.
This prevents
subsequent LUN reassignments from affecting the job.
Finally, a job
file sequence number is assigned. Sequence number 1 is assigned to
the first iob submitted on a particular date, 2 to the second job, and
so on. The sequence number, taken in conjunction with the submittal
date, is a unique job 10. The QJOB directive event variable is set to
the job file sequence number.

6.1.3

Batch Processor

(BATCH)

BATCH emulates a user at a terminal.
TDV treats BATCH

as

though

it

After selecting a job for execution,
BATCH simulates a CTRL/T and
responds to the TDV login prompter.
BATCH then enters commands and
data, iust as a user might.
The only difference is that BATCH gets
the command and data lines from the job file.
BATCH is controlled by the MCR aPR command.
aPR interfaces with BATCH
via a Batch control vector, whose address is stored in SCaM.
BATCH prints several messages
(primarily error messages)
on the
operator log or listing device.
The bulk of the operator log,
however, is printed by JOB ... and END •.. , which also print the job
header and trailer pages.
BATCH provides extensive
information
describing the job to these tasks.
For details of the job information
format, refer to the source code listing of JOB.nn SRC and END.nn SRC.

6.1.4

Job Startup Processor (JOB ... )

JOB ... determines the job account number, stores the number
in the
account file, prints the job header page and prints the operator log.
This is done using information provided by BATCH in the form of input
lines that JOB ... reads. One line is an image of the $JOB line, from
which the account number is determined.
The format of the other lines
is documented in the source code listing of JOB.nn SRC.

BATCH OPERATIONS
6.2.2

READ

BATCH satisfies a READ function by using a line from the job file.
The event variable is always set to +2 (as though the request line
were terminated with a carriage return),
regardless of the line
terminator.
Input lines are restricted to 132 characters.
Only the
lOPS ASCII data mode is supported for BATCH input.
In response to a read request from TDV,
BATCH always supplies a
control line.
The first character of each control line is $. An
exception to this is $EOF, which
is considered a data
line.
Intervening data lines are skipped (ignored) until a control line is
found.
In response to a read request from any other task, BATCH supplies a
data line.
If any task other than TDV attempts to read a control
line, an end-of-file indication is returned and the requesting task is
aborted.
Exceptions to the previous rules are $LOG,
$MSG,
$PAUSE and $EJECT
lines.
Each of these is processed internally by BATCH and can be
intermixed with both control and data lines.

6.2.3

WRITE

BATCH normally satisfies a WRITE function by transmitting output lines
to the listing device. Only the lOPS and Image ASCII data modes are
supported for BATCH output.
lOPS ASCII lines are restricted to 132
characters.
Image ASCII lines are restricted to 80 characters.
Longer lines are truncated.
A special feature of the BATCH WRITE function allows selected output
lines to be omitted from the listing file.
This feature is used to
avoid printing command prompters and other support messages that are
of no value in a BATCH iob listing.
TDV uses this feature to avoid
printing command prompters ("TDV);') on the job listing.
Use of the selected-output feature is controlled by the sign bit in
the line buffer header word (the word containing the word-pair count).
If the sign bit is zero
(the normal case), the output line is
transmitted to the listing device.
If the sign bit is set to one, the
output line is not transmittd to the listing device,
and the write
request event variable is immediately set to +1.
When transmitting a line to the listing device, BATCH first copies the
line into an internal buffer. The request event variable is set to +1
when the copy is complete.
Listing errors are not returned to the
user task.
They are handled by BATCH.
BATCH responds to a listing
error by aborting the current task and
immediately terminating the
current job file.
The error
is reported to the Job Termination
Processor (END •.. ), which prints an error message on the operator
console.

If the formula yields a result of zero, a priority of 1 is
used.
If the formula yields a result greater than 131071, the value
131071 is used.

6.3.2

Other Selection Factors

From the job request list, BATCH selects the job request having the
highest priority.
If two priorities are the same, the job that has
been waiting longest is favored.
The job file name and other
descriptive
information is taken from the job queue node. The job is
then run.

6.4

JOB FILES

BATCH assigns a priority to each job file. The job file is the unit
of work submitted by the QUEUE command or QJOB directive. A job file
is a file on file-oriented devices, or a sequence of input lines
(appropriately terminated) on other devices. A job file is terminated
by the first occurrence of an end-of-file indicator, a $END card, a
$QUIT card or an I/O error.
Job files from non-file-oriented devices are normally stacked on a
disk.
This function is performed by the QUEUE command.
BATCH has
been optimized for this mode of operation.

6.4.1

Multiple Jobs

A job file can contain several jobs by separating them with $JOB
lines.
The entire job file is treated as a unit for scheduling and
time-limit purposes. Each job has separate header and trailer pages,
and is separately entered in the account file.
If any job in a job
file is terminated abnormally (i.e., for any reason other than reading
a $JOB line), the remaining jobs in the job file are not run.

6.4.2

Printing Control Lines

Most control lines (those with $ as the first character)
are printed
on the listing device only.
Exceptions to this are $JOB, $END, $QUIT
and $EJECT lines, which are not printed anywhere.
The effects of
these lines, however, are visible in job listings and the operator
loq.
$MSG and $PAUSE lines are printed on both the listing device and
operator log. Data lines are not printed anywhere.

APPENDIX A
BATCH SYSTEM INSTALLATION CHECKLIST

Before installing the Batch System, the system manager must choose
several LUNs and UFDs to be used. Most of these are used by BATCH and
are assembly parameters to module BDRES. Others are specified when
assembling SC.OPR.
BATCH requires two LUNs for its exclusive use, plus a third LUN for
the operator log. The exclusive LUNs are used to access the input and
listing devices. BATCH assigns appropriate devices to these LUNs for
each job file run.
LUNs 6 and 7 are normally used for this. The
operator log is normally printed on the MCR terminal via LUN 3. In a
heavily used system, it may be desirable to use a different LUN and
dedicate a terminal printer to the operator loq. LUN assignments are
specified using the JOBLUN, LSTLUN and OPRLUN assembly parameters to
BDRES.
BATCH must know the location of the account file so that appropriate
device assignments can be made for JOB ... and END ...• The account
file device name and unit are specified using assembly parameter
ACCTDEV to BDRES.
The UFD is specified using assembly parameter
ACCTUFD. The default location of the account file is the system disk,
unit zero, UFD RSX.
The account file name is defined by a DATA
statement in source code files JOB.nn, END.nn, ACI.n and ACD.n.
The only other LUN assignment required is for the OPR SCHEDULE
command. The LUN used to access schedule files is specified using the
SCHLUN assembly parameter to SC.OPR. The default LUN is 8.
The MCR
REASSIGN command must be used to assign the correct disk and UFD to
this LUN.
After assigning the previously described parameters, install the Batch
System using the followinq checklist.

BATCH SYSTEM ERRORS

B.l

GENERAL

BATCH contains extensive error-checking code to ensure reliable
operation.
Errors that affect only the current job cause the job to
be terminated. Errors are reported to the Job Termination Processor
(END ••• ), which prints them on the operator loq and job trailer page.
Other errors, particularly those that prevent all jobs from being
processed, are referred to as Batch System errors. Batch System
errors abort batch processing and are reported on the operator log in
the form:
BATCH SYSTEM ERROR nnn
error description
where nnn is a code identifyinq the source of the error.
The error
description provides useful information to system programmers familiar
with BATCH. After printinq the message, BATCH disconnects from the
PDVL node and exits.
If an I/O error is detected while BATCH is printing an error message,
BATCH arranges for OPR to report the message. The error code number
is saved and subsequently printed by OPR. In this event, however, the
error description is not printed.
Most Batch System errors are in response to some major inconsistency
in the operation of BATCH, the TDV Poller or some other component of
the MULTIACCESS feature. These errors are meaninqful only to someone
knowledgeable in the internal implementation of the components. These
errors should be treated as software faults and be reported via the
standard SPR procedure. Copies of the operator log, job file and job
listings should be submitted with the SPR.
Some Batch System errors can result
from
incorrect
software
installation or related errors.
These errors are listed in the
following section with appropriate corrective actions.

BATCH SYSTEM ERROR 301
ASSIGN FAILURE--CANNOT ASSIGN LP
Explanation:

BATCH requires the use of a line printer
(device
name LP)
as a listing device.
This message
appears if BATCH is requested and the line printer
is not available.
This error is detected after a
job has already
been removed from a job request queue.
That job
request is irretrievably lost.
.

Correction:

XVM/RSX VlB

Choose one of the following:
1.

Don't use BATCH.

2.

Modify the device handler for
device to act as device name LP.

BATCH SYSTEM ERRORS
3.

Modify BATCH modules BDOPEN and BDMSSG to use
some other device as the default listing
device.

In general, recovery from Batch System errors should be done by
restarting BATCH using the OPR BATCH command.
It is frequently
necessary to assign the BATCH ~nput and listing LUNs to NONE.
If BATCH aborts because of a bad CAL or other unexpected cause, a
Batch System error should deliberately be caused in order to properly
reinitialize the BATCH PDVL node.
Batch System error 102 can be
caused by assigning a device to the BATCH input LUN and requesting
BATCH.
