10 RJE/Remote Job Entry/V Technical Data For HP 3000 MPE/V Computer Systems Product Number 30248A RJE/Remote Job Entry/V and BSC Link allow an HP 3000 system to emulate the major functions of an IBM 2780 or IBM 3780 workstation. RJE can transmit batch jobs to, and receive output from, a host processor that can support standard IBM 2780/3780 devices. [Figure 1 (RJE/V) Caption: none] Additionally, RJE can exchange files between an HP 3000 and many other processors that emulate standard IBM 2780/3780 devices. RJE 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 the HP 3000 to emulate an IBM 2780 or 3780 workstation, using a point-to-point connection to the host. o Provides a way of exchanging files between HP 3000s and many other systems that emulate standard IBM 2780 or 3780 devices. o Allows users to submit jobs and receive output programmatically. o Provides flexibility with regard to the devices used for input and output; any HP 3000 I/O device may be used. o Can be used concurrently with other HP 3000 applications. o Works over X.21 circuit-switched networks in Europe. o Optionally performs data compression. o Optionally allows transparent mode transmission, thus allowing transmission of any arbitrary binary data stream. o Allows specification of Native Language Support for data transmission. 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 RJE and BSC Link allow an HP 3000 system to emulate the major features of an IBM 2780 or IBM 3780 workstation. Using RJE, one can transmit batch jobs to, and receive output from, a host processor that can support standard IBM 2780/3780 devices. Additionally, one can use RJE and BSC Link to exchange files between an HP 3000 and many other processors that emulate standard IBM 2780/3780 devices. An HP 3000 and an HP 2680 Laser Printer can use RJE and BSC Link to act as a high-speed print station for a host computer. Remote sites with an HP 3000 Series 40, or newer model, can get the maximum printer output by using a 56 Kbps Dataphone Digital Service (DDS) line and an external 56 Kbps clock signal. RJE makes it possible for multiple users to submit jobs and receive output programmatically. Users can create files consisting of a set of commands; a user-written program can then submit the names of these command files to a message file. The RJE Subsystem sequentially scans the message file and executes commands encountered in each of the command files. The RJE Subsystem can be set up to go into a continuous receive mode after it has finished executing all the command files. 11 Users can continue to use the RJE Subsystem in a single-user-at-a-time manual mode, if desired. RJE and BSC Link can operate concurrently with all the other processing facilities of the HP 3000. This allows HP 3000 users to perform such functions as the Database Management, Transaction Processing, Data Collection, and program development locally, while being able to transmit collected data (orders, payroll, etc.) or large CPU bound jobs, to a remote host for further processing. By setting appropriate parameters, RJE allows transmission of binary data streams (including control characters) and compression of successive and trailing blanks. Successive blanks are replaced by a 2-byte sequence, a control character, and the number of blanks. This makes job transmission more efficient, particularly at a lower speed. In an IBM 2780 system an end of medium (EM) mark is required before the trailing blanks in each record. RJE truncates trailing blanks when the truncate option is specified, no EM marks are required. However, when EM marks are present they perform the intended function. RJE accepts both horizontal tabulation and vertical form control codes. It recognizes host carriage control characters and translates them to the corresponding characters for the HP 3000 printers. This makes it possible to print specially formatted forms. However, when special forms are used, output must be manually directed to the printer on which the appropriate form is mounted. Functional Specifications RJE emulates all standard features of the IBM 2780/3780 systems except that it does not accept the six-bit transcode. RJE has a set of high-level user commands that make it easy to use. The following is a list of these commands: ________________________________________________________________________ Command Function ________________________________________________________________________ #:MPE Command Enables the user to execute many MPE/V commands from RJE by preceding the command with a colon. ________________________________________________________________________ #RJCMDFILE Causes RJE to take its commands from another file. ________________________________________________________________________ #RJCOMMENT Provides a method for inline comments. ________________________________________________________________________ #RJCONTINUE Enables user to provide a procedure to evaluate errors and provide limited direction for error handling. ________________________________________________________________________ #RJHELP Displays a help screen showing the RJE/V commands and each command's description and syntax. ________________________________________________________________________ #RJLINE Defines the characteristics of the communications line. ________________________________________________________________________ #RJIN Transmits input data from your HP 3000 Computer System to the remote processor. ________________________________________________________________________ #RJOUT Requests and processes routed output from the remote processor. ________________________________________________________________________ 12 #RJIO Initiates transmission of a one-line message to the remote processor. ________________________________________________________________________ #RJINFO Initiates a file display printing of the communications lines. ________________________________________________________________________ #RJLIST Requests and processes unrouted list output from the remote processor. ________________________________________________________________________ #RJPUNCH Requests and processes unrouted punched output from the remote processor. ________________________________________________________________________ #RJEOD Transmits an EOT control character (end-of-file) to the remote processor after sending the last buffer from an RJIN command. ________________________________________________________________________ #RJEND Terminates the HP RJE subsystem. ________________________________________________________________________ #RJSTAT Provides statistical information on frequency of subsystem command use, elapsed times, and tallies of data transmitted and received. ________________________________________________________________________ Product Requirements o An HP 3000 running the current version of the MPE Operating System. o HP 30251A BSC Link. o An IBM System/370-compatible host running a job entry subsystem that supports 2780/3780 (RJE) protocols. o A data communications line between the HP 3000 and the IBM host that can be either nonswitched (leased) or switched (dial-up). Installation and Configuration Policy RJE/V is customer installable. However, Hewlett-Packard will perform minimum configuration of RJE/V in order to verify minimum product functionality. This task, performed by HP, is included in the product purchase price. 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 RJE/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 RJE/V. 13 o Updating the HP 3000 system to the proper release level and installing the RJE/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 by entering the RJE command and observing the version stamp in the RJE/V banner. 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 RJE/V. The customer is also responsible for completing the configuration in order to fully integrate RJE/V into the existing customer network after HP has completed the minimum configuration RJE/V. HP Responsibility Following the installation of RJE/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 RJE/V product to a minimum configuration in order to verify software and hardware functionality. o Verifying the RJE/V configuration by sending a sign-on card when communicating with a host mainframe or issuing the RJLINE command when communicating with other systems. These steps complete HP's portion of the installation and minimum configuration of RJE/V. HP effort spent on problems that 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.
