HP-UX SNAplus2 RJE

Product brief: HP 9000 Servers and Workstations

Key features

• Emulates the functions of an IBM 3770 RJE workstation
• Supports local queuing and management of jobs on a job spool
• Enables multiple logical units (LUs) and multiple output devices per workstation, allowing different RJE configurations for different applications
• Allows variable data records of up to 248 characters Supports file transfer with ASCII-EBCDIC conversion or binary transfer with no translation
• Allows printer, punch, or exchange output to be sent to a disk file, piped to an HP-UX program, including passthrough of peripheral data information records (PDIRs)

HP-UX SNAplus2 RJE is part of the next-generation SNAplus2 Release 5 family of products that provide batch data transfer between an HP 9000 server and/or workstation and an IBM mainframe host in a systems network architecture (SNA) environment. The HP 9000 running SNAplus2 RJE emulates a standard subset of capabilities of an IBM 3770.
The HP-UX SNAplus2 RJE product is available in two configurations: standalone and client/server. The standalone configuration provides IBM mainframe host access for a single HP 9000 computer that has its own HP-UX SNAplus2 Link. The client/server configuration permits access to the IBM mainframe from multiple HP 9000 computers on an Ethernet or Token Ring LAN. These computers generally use a single HP 9000 computer with the HP-UX SNAplus2 Link as a gateway server to access the IBM mainframe.
The HP-UX SNAplus2 Link provides the major features of an IBM 3274 cluster control unit and the lower four levels of SNA. Physical Unit Type 2 and Type 2.1 (PU 2 and PU 2.1) are emulated; Logical Unit Types 0, 1, 2, 3, and 6.2 (LU 0, LU 1, LU 2, LU 3, and LU 6.2) are supported.

Functional specifications

• Using SNAplus2 RJE and a high-speed printer, an HP 9000 can be used as a remote print station for an IBM host. This is an effective way for users at remote sites to print large reports from IBM hosts.
• SNAplus2 RJE does not require a dedicated processor. Concurrently, while reports are being received, the HP 9000 can be used for other tasks such as another session with an IBM host or program development.
• SNAplus2 RJE can be used to access or update databases. SNAplus2 RJE may be used to transmit large files to a centralized database and then to periodically receive an updated copy of the entire database or portions of it-thus enabling data warehouse-type applications.
• With SNAplus2 RJE and SNAplus2 3270 sharing an SNAplus2 Link, users have the capability of both batch and interactive communications. This allows programmers to do development work using SNAplus2 3270 and then run larger batch jobs with SNAplus2 RJE.
• Files can be sent and received in binary mode. Translation between ASCII and EBCDIC is not done, allowing transmission of binary data such as graphics data files.
• All printers and terminals supported by HP 9000 servers and workstations running HP-UX are supported by HP-UX SNAplus2 RJE.
• The SNAplus2 RJE user interface has commands for submitting a job, displaying job queue and workstation status, and sending and receiving console commands (see table of user commands on next page). These commands can be used interactively. The HP 9000 will concurrently process user applications and data communications with an IBM mainframe.
• SNAplus2 RJE runs in the background. As a result, jobs may be queued or status may be checked at any time the SNA daemon is running. Jobs submitted to the host are held in a transmission queue and automatically sent to the host when a session is established. Output from the host can be received at any time a host session is active, even when the user has logged off.
• Output can be configured to be sent to a file, directory, or user-supplied post-processor. Additionally, the user can specify the destination of the output with a usr card in the job.
• The rjeusr and rjeusrpad postprocessors will then direct the output to the specified file, directory, or post-processor.
• Printer output may be formatted using FCBs. These are defined locally and can be specified in the outbound data using the PDIR. If the PDIR is not used to select an FCB, a configured default FCB is used. Printer output may also be formatted by SCS codes.

Features

• Communications with MVS/JES2 (Multiple Virtual Storage/Job Entry Subsystem), MVS/JES3, and VSE/Power (Virtual Storage Extended).
• Jobs can be submitted to the host through a script file. Host output can be routed to a disk file or piped as standard input to a program or shell script, allowing flexibility in job processing.
• Jobs may be submitted when the workstation is not active; this allows time-deferred transmission of the jobs.
• Host console commands can be sent and host console data can be received interleaved with file transmission or receipt.
• Notification of output via mail or message to the user's terminal when using usr card routing.
• The RJE process (on HP-UX) runs in the background and uses a simple send command to initiate a transmission. The background process will accept data from the host without user intervention, reducing operator costs.
• Security-access is restricted to a group of users.
• Multiple RJE workstations can be configured on a single SNAplus2 RJE system to provide different RJE configurations for different groups of users.
• Jobs submitted for a remote system are queued locally on a spool before being sent to the remote system.
• SNAplus2 RJE provides an RJE style file for configuring RJE workstation parameters, forms control blocks (FCBs), printers, and punches, reducing configuration costs.
• Configurable parameters provide the following options: retaining spool file information about jobs after they have been successfully sent to the host; a separate job log provides information about spooled and sent jobs as well as received and routed output.
• Up to 9 printer and 9 punch output devices may be configured for each RJE workstation.
• A full-screen console program allows you to view host system console information for an RJE workstation and to issue commands to JES.
• PDIRs are accepted for both print and punch output.
• ASCII to EBCDIC code conversion is supported.
• Allows specification of variable record size of 80 to 248 bytes for inbound punch and exchange data.
• Inbound and outbound data compression is supported.
• Up to 5 LUs on the same host connection may be configured for each RJE workstation.
• A device can be configured to send output to the rjeusr or rjeusrpad programs which route output according to a usr card specification.
• A configuration option enables padding of punch output.
• Supports printer forms control by SNA Character Strings (SCS) or by using FCBs.
• A configuration option is provided for retaining incomplete output after a transmission failure.

Customer installation responsibility

Installation of these products requires knowledge in several overlapping areas. The staff engineer responsible for this task must have strong knowledge of (or have direct contact with staff with strong knowledge of) SNA networks, application environments, and HP-UX system administration.
Installation requires basic SNA knowledge. This includes knowledge of interface nodes, network routers, NAUs, PUs, LUs, link types, IBM hardware, and software. The installer must understand why the SNAplus products are being installed, how the users are going to use SNAplus, and how SNAplus fits into the network solution.
Installation of SNAplus requires a thorough user-level knowledge of HP-UX commands. In addition, the installer must be familiar with the following:

• Running SD commands on an HP-UX system
• Running SAM (in order to add users)
• The HP-UX file system, privilege groups, and real-time features running LAN and PSI diagnostics on an HP-UX system
• HP-UX kernel configuration
