PROPOSED REMOTE JOB ENTRY PROTOCOL
Remote job entry is the mechanism whereby a user at one location
causes a batch-processing job to be run at some other location. This
protocol specifies the Network standard procedures for such a user to
communicate over the Network with a remote batch-processing server,
causing that server to retrieve a job-input file, process the job,
and deliver the job's output file(s) to a remote location. The
protocol uses TELNET (to a special standardized logger, not socket 1)
connection for all control communication between the user and the
server RJE process. The server-site then uses the File Transfer
Protocol to retrieve the job-input file and to deliver the output
file(s).
There are two types of users: direct users (persons) and user
processes. The direct user communicates from an interactive terminal
attached to a TIP or any host. This user may cause the input and/or
output to be retrieved/sent on a specific socket at the specified
host (such as for card readers or printers on a TIP), or the user may
have the files transferred by pathname using File Transfer Protocol.
The other type of user is an RJE User-process in one remote host
communicating with the RJE Server-process in another host. This type
of user ultimately receives its instructions from a human user, but
through some unspecified indirect means. The command and response
streams of this protocol are designed to be readily used and
interpreted by both the human user and the user process.
A particular user location may choose to establish the TELNET control
connection for each logical job or may leave the control connection
open for extended periods. If the control connection is left open,
then multiple job-files may be directed to be retrieved or optionally
(to servers that are able to determine the end of one logical job by
the input stream and form several jobs out of one input file) one
continuous retrieval may be done (as from a TIP card reader). This
then forms a "hot" card reader to a particular server with the TELNET
connection serving as a "job monitor". Since the output is always
transferred job at a time per connection to the output socket, the
output from this "hot" reader would appear when ready as if to a
"hot" printer. Another possibility for more complex hosts is to
attach an RJE User-process to a card reader and take instructions
from a lead control card, causing an RJE control TELNET to be opened
to the appropriate host with appropriate logon and input retrieval
commands. This card reader would appear to the human user as a
Network "host" card reader. The details of this RJE User-process are
beyond the scope of this protocol.
GENERAL SPECIFICATIONS
1. User - A human user at a real terminal or a process that
supplies the command control stream causing a job to be
submitted remotely will be termed the User. The procedure by
which a process user receives its instructions is beyond the
scope of this protocol.
2. User TELNET - The User communicates its commands over the
Network in Network Virtual Terminal code through a User TELNET
process in the User's Host. This User TELNET process initiates
its activity via ICP to the standard "RJE logger" socket (socket
5) at the desired RJE-server Host.
3. RJE-server TELNET - The RJE-server process receives its command
stream from and sends its response stream to the TELNET channel
through an RJE-server TELNET process in the server host. This
process must listen for the ICP on the "RJE logger" socket (and
cause appropriate ICP socket shifting).
4. TELNET Connection - The command and response streams for the RJE
mechanism are via a TELNET-like connection to a special socket
with full specifications according to the current NWG TELNET
protocol.
5. RJE-Server - The RJE-Server process resides in the Host which is
providing Remote Batch Job Entry service. This process receives
input from the RJE-Server TELNET, controls access through the
"logon" procedure, retrieves input job files, queues jobs for
execution by the batch system, responds to status inquiries, and
transmits job output files when available.
6. User FTP - All input and output files are transferred under
control of the RJE-server process at its initiative. Those
files may be directly transferred via Request-for-connection to
a specific Host/socket or they may be transferred via File
Transfer Protocol. If the later method is used, then the RJE-
server acts through its local User FTP process to cause the
transfer. This process initiates activity by an active
Request-for-connection to the "FTP Logger" in the foreign host.
7. Server FTP - This process in a remote host (remote from the
RJE-server) listens for an ICP from the User FTP and then acts
upon the commands from the User FTP causing the appropriate file
transfer.
8. FTP - When File Transfer Protocol is used for RJE files, the
standard FTP mechanism is used as fully specified by the current
NWG FTProtocol.
9. RJE Command Language - The RJE system is controlled by a command
stream from the User over the TELNET connection specifying the
user's identity (logon), the source of the job input file, the
status, altering job status or output disposition. Additional
commands affecting output disposition are includable in the job
input file. This command language is explicitly specified in a
following section of this protocol.
10. RJE Command Replies - Every command input from the User via
TELNET and certain other conditions calls for a response message
from the RJE-server to the User over the TELNET connection.
These messages are formatted in a standardized manner to
facilitate interpretation by both human Users and User
processes. A following section of this protocol specifies the
response messages.
RJE COMMANDS OVER TELNET CONNECTION
GENERAL CONVENTIONS
1. All commands will be contained in one input line terminated by
the standard TELNET "crlf". The line may be of any length
desired by the user (explicitly, not restricted to a physical
terminal line width). The characters "cr" and "lf" will be
ignored by the RJE-server except in the explicit order "crlf"
and may be used as needed for local terminal control.
2. All commands will begin with a recognized command name and may
then contain recognized syntactic element strings and free-form
variable strings (for userid, pathnames, etc.). Recognized
words consist of alphanumeric strings (letters and digits) or
punctuation. Recognized alphanumeric string elements must be
separated from each other and from unrecognizable strings by at
least one blank or a syntactically permitted punctuation. Other
blanks may be used freely as desired before or after any
syntactic element. The "=" after the command name in all
commands except OUT and CHANGE are optional.
3. Recognized alphanumeric strings may contain upper case letters
or lower case letters in any mixture without syntactic
differentiation. Unrecognizable strings will be used exactly as
presented with full differentiation of upper and lower case
input, unless the host finally using the string defines
otherwise.
4. There are two types of Unrecognizable strings: final and
imbedded. Final strings appear as the last syntactic element of
a command and are parsed as beginning with the next non-blank
character of the input stream and continuing to the last non-
blank character before the "crlf".
Imbedded strings include "job-id" and "job-file-id" in the OUT,
CHANGE, and ALTER commands. At present these fields will be
left undelimitted since they must only be recognizable by the
server host which hopefully can recognize its own job-ids and
file-names.
SYNTAX: The following command descriptions are given in a BNF-like
syntax. Parenthesized names are non-terminal syntactic elements
which are expanded in succeeding syntactic equations. Each
equation has the defined name on the left of the ::= and a set
of alternative definitions, separated by slashes "/", on the
right. The equations for (host-file) and (disp) use the
characters "/" "( )" explicitly in their definitions. In these
cases the quotes are not part of the definition, but surround
literal text which is part.
USER
USER = (user-id)
This command must be the first command over a new TELNET
connection. As such, it initiates a "logon" sequence. The
response to this command is either
a) User code in error.
b) Enter password (if usercode ok)
c) Log-on ok, proceed. (if no password required)
Another USER command may be sent by the User at any time to change
Users. Further input will then be charged to the new user. A
server may refuse to honor a new user command if it is not able to
process it in its current stat (during input file transfer, for
example), but the protocol permits the USER command at any time
without altering previous activity. An incorrect subsequent USER
command or its following PASS command are to be ignored with error
response, leaving the original User logged-in.
It is permissable for a server to close the TELNET connection if
the initial USER/PASS commands are not completed within a server
specified time period.
It is not required or implied that the "logged-on" User be the
user-id used for file transfer or job execution, but only
identifies the submitter of the command stream. Servers will
establish their own rules relating User-id with the job-execution-
user for Job or Output alteration commands.
Successful "log-on" always clears any previous Input or Output
default parameters (INID, etc.).
PASS
PASS = (password)
This command immediately follows a USER command and completes the
"log-on" procedure. Although a particular Server may not require
a password and has already indicated "log-on ok" after the USER
command, every Server must permit a PASS command (and possibly
ignore it) and acknowledge it with a "log-on ok" if the log-on is
completed.
BYE
BYE
This command terminates a USER and if input transfer is not in
progress, closes the TELNET connection. If input is in progress,
the connection will remain open for result response and will then
close. During the interim, a new USER command (and no other
command) is acceptable.
An unexpected close on the TELNET connection will cause the server
to take the effective action of an ABORT and BYE.
INID/INPASS
INID = (user-id)
INPASS = (password)
The specified Userid and Password will be sent in the File
Transfer request to retrieve the input file. These parameters are
not used by the Server in any other way. If this command does not
appear, then the USER/PASS parameters are used.
INPATH/INPUT
INPATH = (pathname)
INPUT = (pathname)
INPUT
NOTE: The following syntax will also be used for output
(pathname).
(pathname)::= (host-socket) / (host-file)
(host-socket)::= (host),(socket) / (socket)
no (host) part implies the User-site host
(host)::= (decimal-integer) / (standard-host-name)
(socket)::= (decimal-integer) / PORT (decimal-integer)
(decimal-integer) implies explicit socket, lower bit
will be set appropriately for the direction
PORT implies the specified port-sockets for a TIP
Tip-Socket = Port * 2**16 + (2 or 3)
(host-file)::= (host)(attributes)"/"(file-name)
(attributes)::= (empty) / : (transmission)(code)
(transmission)::= (empty) / T / A / N
(empty) implies default which is
N for Input files
A for output files
T specifies TELNET-like coding with imbedded "crlf"
for new-line, "ff" for new-page
N specifies FTP blocked transfer with record marks
but without other carriage-control
A specifies FTP blocked records with ASA carriage-
control (column 1 of image is forms control)
(code)::= (empty) / E
(empty) specifies NVT ASCII code
E specifies EBCDIC (TE not allowed)
(file-name)::= (any string recognized by the
FTP Server at the site of the file)
The (pathname) syntax is the general RJE mechanism for specifying a
particular file source or destination for input or output. If the
(host-socket) form is used then direct transfer will be made by the
RJE-Server to the named socket using TELNET-like ASCII. If the
(host-file) form is used then the RJE-server will call upon its local
FTP-user process to do the actual transfer. The data stream in this
mode is either TELNET-like ASCII or blocked records (which may use
column 1 for ASA carriage-control). Although A mode is permitted on
input (column 1 is deleted) the usual mode would be the default N.
The output default A would supply carriage-control in the first
character of each record ("blank"= single-space, "1"=new-page, etc.),
while the optional N mode would transfer the data only (as to a card
punch, etc.).
The (file-name) is an arbitrary Unrecognized string which is saved by
RJE-server and sent back over FTP to the FTP-server to retrieve or
store the appropriate files.
INPATH or INPUT commands first store the specified (pathname) if one
is supplied, and then the INPUT command initiates input. The INPATH
name may be used to specify a pathname for later input and the INPUT
command without pathname will cause input to initiate over a
previously specified pathname. An INPUT "crlf" command with no
previous (pathname) specified is illegal.
ABORT
ABORT
This command aborts any input retrieval in progress, discards
already received records, and closes the retrieval connection.
Note: ABORT with parameters is an Output Transmission control.
OUTUSER/OUTPASS
OUTUSER = (user-id) OUTPASS = (password)
The specified Userid and Password will be sent in the File
Transfer request to send the output file(s). These parameters are
not used by the Server in any other way. If this command does not
appear, then the USER/PASS parameters are used.
OUT
OUT (out-file) = (disp)(pathname)
(out-file)::= (empty) / (job-file-id)
(empty) implies the primary print file of the job
(job-file-id)::= (string representing a specific output file
from the job as recognized by the Server)
(disp)::= (empty) / "(H)" / "(S)" / "(D)"
(empty) specifies Transmit then discard
(H) specifies Hold-only, do not transmit
(S) specifies Transmit and Save
(D) specified discard without transmitting
Note: Parentheses are part of the above elements.
(pathname) see INPUT command
This command specifies the disposition of output file(s) produced
by the job. Unspecified files will be Hold-only by default. The
OUTUSER, OUTPASS, and OUT commands must be specified before INPUT
command to be effective. These commands will affect any following
jobs submitted by this USER over this RJE-TELNET connection. A
particular job may override these commands by NET control cards on
the front of the input file.
Once output disposition is specified by this OUT command or by a
NET OUT card, the information is kept with the job until final
output disposition, and is modifiable by the CHANGE command.
OUTPUT RE-ROUTE
CHANGE (job-id)(out-file) = (disp)(pathname)
This command changes the output disposition supplied with the job
submission. The (job-id) is assumed recognizable by the RJE-
server, who may verify if this USER is authorized to modify the
specified job. After the job is identified, the other information
has the same syntax and semantics as the original OUT command.
CHANGE command may be specified for a job-file-id which was not
mentioned at submission time and has the same effect as an
original OUT command.
OUTPUT CONTROLS DURING TRANSMISSION
(command)(count)(what)
(command)::= RESTART / RECOVER / BACK / SKIP / ABORT / HOLD
these commands specify
Restart the transmission (new RFC, etc.)
Recover restarts transmission from last
FTP Restart-marker-reply (see FTP).
Back up the output "count" blocks
Skip the output forward "count" blocks
Abort the output, discarding it
Hold the output after Aborting it
(count)::= (empty) / (decimal-integer)
(empty) implies 1 where defined
(what)::= @(pathname) / (job-id)(job-file-id)
(pathname) is as in the INP command
(job-id)::= (server recognized job identifier which was
supplied at INP completion by the server)
(job-file-id)::= (server recognized file identifier or
if missing then the prime printer output
of the specified job)
This collection of commands will modify the transmission of output
in progress or recently aborted. If output transmission is cut-
off before completion, then the RJE-server will either try to
resend the entire file if the file's (disp) was Transmit-and-
discard or will Hold the file for further User control if the
(disp) was (S) transmit-and Save. Either during transmission,
during the Save part of a transmit-and-Save, or for a Hold-only
file; the above commands may be used to control the transmission.
The @(pathname) form of (what) is permitted only if transmission
is actually in progress.
If the file's state is inconsistent with the command then the
command is illegal and ignored with reply.
STATUS
STATUS
STATUS (job-id)
These commands request the status of either the RJE-server or a
particular job respectively. The information content of the
Status reply is site dependent.
CANCEL/ALTER
CANCEL (job-id)
ALTER (job-id) (site dependent options)
These commands change the course of a submitted job. CANCEL
specifies that the job is to be immediately terminated and any
output discarded. ALTER provides for system dependent options
such as changing job priority, process limits, Terminate without
Cancel, etc.
OP
OP (any string)
The specified string is to be displayed to the Server site
operator when any following job is initiated servicing from the
batch queue of the Server. This command usually appears in the
input file as a NET OP control card, but may be a TELNET command.
It is cancelled as a all-jobs command by an OP "crlf" command (no
text supplied).
RJE CONTROL CARDS IN THE INPUT FILE
Certain RJE commands may be specified by control cards in the front
of the input file. If these controls appear, they take precedence
over the same command given thru the RJE-TELNET connection and affect
only this specific job.
All these RJE control cards must appear as the first records of the
job's input-file. They all contain the control word NET in columns
1-2. Scanning for these controls stop when the first card without
NET in col 1-3 is encountered.
The control commands appear in individual records and are terminated
by the end-of-record (usually an 80 column card-image). Continuation
is permitted onto the next record by the appearance of NET+ in
columns 1-4 of the next record. Column 5 of the next record
immediately follows the last character of the previous record.
NET OUTUSER = (userid)
NET OUTPASS = (password)
NET OUT (out-file) = (disp)(pathname)
NET OP (any string)
See the corresponding TELNET commands for details. One option
permitted by the NET OUTUSER and NET OUT controls not possible from
the TELNET connection is specification of different OUTUSERs for
different OUTs, since the TELNET stores and supplies only an initial
OUTUSER, but the controls may change OUTUSERs before each OUT control
is encountered.
RJE USE OF FILE TRANSFER PROTOCOL
Most non-TIP files will be transferred to or from the RJE-server
through the FTP process. RJE-server will call upon its local FTP-
user supplying the Host, File-pathname, User-id, Password, and Mode
of the desired transfer. FTP-user will then connect to its FTP-
server counterpart in the specified host and set up a transfer path.
Data will then flow through the RJE-FTP interface in the Server, over
the Network, from/to the foreign FTP-server and then from/to the
specified File-pathname in the foreign host's file storage space. On
output files, the file-pathname may be recognized by the foreign host
as directions to a printer or the file may simply be stored; a User-
RJE-process can supply output (pathname) by default which is
recognized by its own Server-FTP as routing to a printer.
Although many specifics of the RJE-Server/User-FTP interface are
going to be site dependent, there are several FTP options which will
be used in a standard way by RJE-Servers:
1. A new FTP connection will be initiated for each file to be
transferred. The connection will be opened with the RJE User
supplied User-id (OUTUSER or INUSER) and Password.
2. The data bytesize will be 8 bits.
3. The FTP Type, Structure, and Mode parameters are determined by
the RJE transfer direction (I/O), the (transmission and (code)
options supplied by the User:
I/O (TRANS) (CODE) FTP TYPE STRUCTURE MODE
----------------------------------------------------
I* N - Ascii R Hasp
I N E Image R Hasp
I T - Ascii F Ascii
I A - Ascii R Hasp
I A E Image R Hasp
O* A - Ascii-print R Hasp
O A E Ebcdic-print R Hasp
O N - Ascii R Hasp
O N E Image R Hasp
O T - Ascii-print F Ascii
Note: The I* and O* are the default cases.
4. The service commands used will be Retrieve for input and Append
(with create) for output. The FTP pathname will be the (file-
name) supplied by the RJE User.
5. On output in Hasp form, the User-FTP at the RJE-Server site will
send Restart-markers at periodic intervals (like every 100
lines, or so), and will remember the latest Restart-marker-reply
with the file. If the file transfer is not completed and the
(disp) is (S) then the file will be held pending User
intervention. The User may then use the RECOVER command to
cause a FTP restart at the last remembered Restart-marker-reply.
6. The FTP Abort command will be used for the RJE ABORT and CANCEL
commands.
The specific form of the FTP commands used by an RJE-Server site, and
the order in which they are used will not be specified in this
protocol.
Errors encountered by FTP fall into three categories: a)access errors
or no storage space error; b)command format errors; and c)transfer
failure errors. Since the commands are created by the RJE-Server
process, an error is a programming problem and should be logged for
attention and the situation handled as safely as possible.
Transmission failure or access failure on input cause an effective
ABORT and user notification. Transmission failure on output causes
RESTART or Save depending on (disp). (see OUT command.) Access
failure on output is a problem since the User may not be accessible.
A status response should be queued for that user, should he happen to
inquire; a (disp)=(S) file should be Held; and a (disp)=(empty)
transmit-and-discard file should be temporarily held and then
discarded after a reasonable time if not claimed.
REPLIES OVER THE TELNET CONNECTION
Each action of the RJE-server, including entry of each TELNET
command, is noted over the TELNET connection to the User. These
RJE-server replies are formatted for Human or Process interpretation.
They consist of a leading 3-digit numeric code followed by a blank
followed by a text explanation of the message. The numeric codes are
assigned by groups for future expansion to hopefully cover other
protocols besides RJE (like FTP). The numeric code is designed for
ease of interpretation by processes. The three digits of the code
are interpreted as follows:
a) The first digit specifies the "type" of response indicated:
000 These "replies" are purely informative, and are issued
voluntarily by the Server to inform a User of some state of
the server's system.
100 Replies to a specific status inquiry. These replies server as
both information and as acknowledgement of the status request.
200 Positive acknowledgement of some previous command/request.
The reply 200 is a generalized "ok" for commands which require
no other comment. Other 2xx replies are specified for
specific successful actions.
300 Incomplete information supplied so far. No major problem, but
activity can not proceed with the input supplied.
400 Unsuccessful reply. A request was correctly specified, but
could not be correctly completed. Further attempts will
require User commands.
500 Incorrect or illegal command. The command or its
parameters were invalid or incomplete from a syntactic view,
or the command is inconsistent with a previous command. The
command in question has been totally ignored.
600-900 Reserved for expansion.
b) The second digit specifies the general subject to which the
response refers:
x00-x29 General purpose replies, not assignable to other subjects.
x30 Primary access. There replies refer to the attempt to "log-
on" to a Server service (RJE, FTP, etc.).
x40 Secondary access. The primary Server is commenting on its
ability to access a secondary service (RJE must log-on to a
remote FTP service).
x50 FTP results.
x60 RJE results.
x70-x99 Reserved for expansion.
c) The final digit specifies a particular message type. Since the
code is designed for an automation process to interpret, it is not
necessary for every variation of a reply to have a unique number,
only that the basic meaning have a unique number. The text of a
reply can explain the specific reason for the reply to a human
User.
Each TELNET line (ended by "crlf") from the Server is intended to be
a complete reply message. If it is necessary to continue the text of
a reply onto following lines, then those continuation replies contain
the special reply code of three blanks.
The assigned reply codes relating to RJE are:
000 General information message (time of day, etc.)
030 Server availability information
050 FTP commentary or user information
060 RJE or Batch system commentary or information
100 System status reply
150 File status reply
151 Directory listing reply
160 RJE system general status reply

SEQUENCING OF COMMANDS AND REPLIES
The communication between the User and Server is intended to be an
alternating dialogue. As such, the User issues an RJE command and
the Server responds with a prompt primary reply. The User should
wait for this initial success or failure response before sending
further commands.
A second type of reply is sent by Server asynchronously with respect
to User commands. These replies report on the progress of a job
submission caused by the INPUT command and as such are secondary
replies to that command
The final class of Server "replies" are strictly informational and
may arrive at any time. These "replies" are listed below as
spontaneous.
