BSC MRJE/V Multileaving Remote Job Entry Technical Data
For HP 3000 MPE/V Computer Systems Product Number 30249A
MRJE/Multileaving Remote Job Entry and BSC Link allow multiple users to
submit batch jobs to or receive output from a host. With the MRJE
facility, the HP 3000 emulates workstations that work with one of the
following job entry systems on the host: JES2, JES3, RSCS, or RES.
[Figure 1 (BSC MRJE/V) Caption: none]
MRJE requires the installation and use of BSC Link. BSC Link manages the
data communications protocol and link between the HP 3000 and the
IBM System/370-compatible mainframe. It contains software, a hardware
interface card, and a cable.
Features
o Allows multiple HP 3000 users simultaneous batch access to the host.
o Provides for automatic management of job output.
o Allows for concurrent use of all the processing facilities of the
HP 3000 such as Program Development, Database Management, and
Transaction Processing.
o Allows any supported I/O device on the HP 3000 to be used for I/O
including the HP 2680 Laser Printer.
o Allows MRJE or IBM host users to specify output spool file
characteristics.
o Allows routing of unsolicited output to any destination device or
file.
o Allows host console commands to be issued from any session.
o Has easy-to-use commands for job control.
o Allows users to schedule jobs even while the communications lines are
down.
o Allows specification of Native Language Support for data transmission.
o NLS 16-bit character mapping; interactive and programmatic access; and
data integrity are not supported for languages such as Japanese,
Korean, Simple Chinese, and Traditional Chinese.
Functional Description
MRJE and BSC Link allow an HP 3000 system to emulate a workstation
operating with JES2 or JES3 Job Entry Systems on the host. With this
facility, multiple HP 3000 users can submit batch jobs to or receive
output from a host system simultaneously.
Use of the MRJE facility does not require the dedication of the
entire system; all other processing facilities of the HP 3000 such as
Database Management and Transaction Processing can be used concurrently
with MRJE and BSC Link.
An HP 3000 and an HP 2680 or 2688 Laser Printer can use MRJE and BSC
Link to act as a print station for a host computer. Remote sites with an
HP 3000 Series 40 through 70 can get the maximum printer output by using
a 56 Kbps Dataphone Digital Service (DDS) line with an external 56 Kbps
clock signal.
Both MRJE and IBM host users can direct their output to HP 2680 and
2688 laser printers and specify spool file output characteristics
including: output priority, number of copies, output device class, and
environment file. Environment files define special predefined forms,
character fonts, and formats.

MRJE allows for automatic job management under a standard IBM Job
Entry System; users can, at the time of job submittal, specify the
particular device to which their job outputs are to be directed. No
further user intervention is required.
Output can be received on any standard output device on the HP 3000
such as tape units, disks, and printers. Similarly, jobs can be input
through any standard input device such as terminals, card readers, or
disk.
Unsolicited output can be routed via host "Special Forms" names to
any destination device or file (such as a disk file or a deferred spool
file).
With MRJE, users can issue host console commands for controlling job
activity. Host console commands can be entered interactively or may be
issued as part of an IBM Job Control Language (JCL) deck; the commands
must conform to the formats specified by the host system. Through the
configuration file the MRJE manager can control the set of commands that
a particular user can issue.
As an example of the host console command, the JES2 $DA command can
be issued to display active jobs, or a $DQ command may be issued to
display job queues.
In addition to the host console commands, MRJE has easy-to-use
commands for job control. These commands may be used for canceling jobs,
displaying job status, and submitting jobs. All such commands may be
issued either interactively through a terminal or through a batch job. A
list of such commands is provided in table 1.
With MRJE, jobs can be submitted whether the communication line
between the host and the HP 3000 is open or closed. Jobs submitted when
the line is closed are spooled on the HP 3000 and automatically
transmitted when the connection is made. Output from the host is also
automatically sent to the HP 3000 and directed to the user-specified
output device.

Functional Specifications
o MRJE and BSC Link operate with the following IBM Job Entry Systems:
- JES2
- JES3
o For the following IBM Job Entry Systems automatic output routing via
the SUBMIT command is not supported:
- RES
- VM/RSCS*
o The MRJE product is compatible with only the standard (default)
generation of IBM Job Entry Systems. When in doubt, confirm MRJE
support of your Job Entry System through your local Hewlett-Packard
representative. There can be 22 devices configured on the HP 3000.
(However, the host will only support a total of 8 printers and punches
at any one time.)
- 7 card readers
- 7 printers
- 7 card punches
- 1 console
Product Requirements
o An HP 3000 running the current version of the MPE Operating System.
o HP 30251A BSC Link.
o A data communications line
- either switched or leased
- between the HP 3000 and the IBM host.
o The IBM host must support one of the following job entry systems:
- JES2
- JES3
- RES
- RSCS
*However, automatic output routing can be performed through a mapping of
the IBM host "Special Forms" name to an MPE "FILE" equation.
Installation and Configuration Policy
MRJE/V is customer installable. However, Hewlett-Packard will perform
minimum configuration of MRJE/V in order to verify minimum product
functionality. This task, performed by HP, is included in the product
purchase price.
10
For product configuration tailored to the customer's specific needs,
or for a complete HP implementation, HP offers a comprehensive range of
integrated and flexible support services. Please refer to the Network
Support data sheets in this guide for more information on these
services.
Customer Responsibility
Prior to having HP personnel onsite to perform minimum configuration of
MRJE/V, the customer is responsible for the following:
o Providing HP with the information necessary to complete the Network
Implementation and Support Plan (NISP) including:
- system configurations
- logical network map identifying relevant traffic flow
- physical network map identifying relevant network hardware
components.
o Verifying that the necessary remote system software is installed and
configured to support MRJE/V.
o Updating the HP 3000 system to the proper release level and installing
the MRJE/V software using AUTOINST. Refer to the HP 3000 Software
Update Manual (32033-90036).
o Verifying that all of the necessary software modules have been
successfully installed by AUTOINST and are at the correct version
levels using the MRJECONTROL CHECK command.
o Performing full system backups as necessary and ensuring that the
HP 3000 system and personnel with HP 3000 system management knowledge
are available when HP is onsite to complete the minimum configuration
of MRJE/V.
The customer is also responsible for completing the configuration in
order to fully integrate MRJE/V into the existing customer network after
HP has completed the minimum configuration of MRJE/V.
HP Responsibility
Following the installation of MRJE/V, HP is responsible for the
following:
o Confirming that all of the necessary software modules have been
installed and are at the correct version level.
o Configuring the MRJE/V product to a minimum configuration in order to
verify software and hardware functionality. This includes configuring
MRJESTR, MRJECON, and MRJETABL for the default host.
o Verifying the MRJE/V configuration by issuing the MRJECONTROL START
command and ensuring MRJE starts without problems.
These steps complete HP's portion of the installation and minimum
configuration of MRJE/V.
HP effort spent on problems which are not caused by HP installation
and configuration activities is considered HP Consulting Support and is
billable to the customer at normal HP time-and-materials rates.
System Environment
MRJE and BSC Link are available on the entire HP 3000 product line
running MPE/V.
