USING NETWORK REMOTE JOB ENTRY
OVERVIEW
As has been mentioned in previous RFCs and at previous Network
meetings various groups at Rand have been doing RJE to remote Network
sites (UCBS and UCLA) for over a year. Until recently all this work
has been done from our IBM 360/65 which is only a Network using host
(not a server). Recently our PDP-10 has come onto the Network as
both a user and server host. We now have, as well, a program on the
PDP-10 allowing access to the Remote Job Service (RJS) at UCLA. Our
normal mode of operation is diagramed below.

User
To use RJS the user creates a job source "deck" in the Rand File
system. He then instructs the RJS Access Program (RJSAP) to send
that file (job) to RJS. (Sample session below.) He can then monitor
the status of his job via RJSAP (and hence RJS) and ask that RJSAP
retrieve his print output to a local file, (or directly to his
console, the line printer or whatever).
Recently, several people at other Network sites have expressed an
interest in using RJS. However, they are located at a minimal Host
or at a host not providing RJS access. Since the Rand PDP-10 is a
Network server, these people can solve their access problem by
logging onto the Rand PDP-10, using Telnet, and running the RJSAP
themselves. The remainder of this RFC describe the steps necessary
Harslem [Page 1]
RFC 307 Using Network Remote Job Entry February 1972
to run that program.
The Rand PDP-10
The Rand PDP-10 operates under the Tenex operating system. Thus,
some understanding of the Tenex Executive is required. The necessary
documents can be obtained from the developers of Tenex:
Bolt, Beranek and Newman, Inc.
50 Moulton Street
Cambridge, Massachusetts 02138
(617) 491-1850
Secondly, it is necessary to establish an account on the Rand PDP-10.
This can be done through:
Rod Fredrickson
The Rand Corporation
1700 Main Street
Santa Monica, California 90406
(213) 393-0411
UCLA Remote Job Service
To use the UCLA IBM 360/91 via RJS it is necessary to:
1) have an account at UCLA
2) have an assigned RJS terminal ID.
These can both be obtained from
Bob Braden
UCLA
Math Sciences Building
3531 Boelter Hall
Los Angeles, Calif. 90024
(213) 825-7518
The RJS Access Program (RJSAP)
A sample session using RJSAP is attached below. The RJSAP is started
by typing "RJS<return>" to the Tenex executive. The program will
then initialize and check (via your login information) to see if you
are a user recorded in its tables. This is done to assure you have a
valid RJS terminal ID. If your ID is not found, the program will
terminate with appropriate message.
Harslem [Page 2]
RFC 307 Using Network Remote Job Entry February 1972
If your ID is found, RJSAP will attempt to connect to RJS. If UCLA
is down, a message to that effect will appear and the program will
terminate. If UCLA is up, RJSAP will connect you to RJS and sign-on
your terminal ID (see RFC 189). RJSAP will respond "YOU ARE
CONNECTED TO RJS."
At this point RJS will acknowledge your signon and print out messages
regarding system status.
The programs (RJSAP and RJS) are now ready to perform RJE functions.
All commands are initially interpreted by RJSAP. They are listed and
explained below.
1. Help
If the user types "?" RJSAP will echo the "?" and list the
valid set of commands (see below).
2. Message to RJS
If the first character of a command is a "/" all subsequent
characters up to a "return" are transmitted to RJS on the
operator input connection. See RFC 189 for the syntax and
semantics of these commands.
An operator input message can be cancelled with the RUB OUT key
or backspaced using BACKSPACE.
3. Send a Job
When the user types "S" RJSAP echoes "SEND SOURCE DECK FROM
FILE". The user then enters the file name containing his job
followed by a "return." Obviously the file must already exist.
If the file is ok and is transmitted successfully, both RJSAP
and RJS will print an acknowledgement on the user's terminal
(see example below).
4. Retrieve Job Output-Printer
The user can retrieve printed output by entering "PR". RJSAP
will echo "PRINT OUTPUT TO FILE". The user then enters the
files name where he wants the output. This can be a new file
or even a device such as the printer or teletype. When the
print output is completely received, the RJSAP will print an
acknowledgment (see example).
Harslem [Page 3]
RFC 307 Using Network Remote Job Entry February 1972
5. Retrieve Job Output-Punch
This function is currently not implemented, pending a decision
on the use of this channel between a PDP-10 and a 360.
6. Transmission Status
For long transmissions of job input or output it may be
desirable to check on the progress of the transmission. Typing
"R" will cause RJSAP to echo "REPORT ON TRANSMISSIONS--",
followed by a record count for the job input and printer output
channels.
7. Termination
If the user types a "Q" at the start of a command, RJSAP will
echo "QUIT IN PROGRESS" and terminate. This is the preferred
way of terminating the program. (Rather than just ^C).
NOTE: Since RJSAP has not been extensively used, we expect it to be
improved and modified in the future. Thus, the last section of this
RFC -- the explanation of the use of RJSAP -- will be kept in file
<HARSLEM>RJSACCESSPROGRAM.EXPLANATION on the Rand PDP-10 and be
updated appropriately.
Sample Session
The follows is a sample session using RJS from RJSAP on the Rand
PDP-10. All user inputs have been underlined (shown as _text_ ).
