HP-UX SNAplus2 RJE provides batch data transfer between an HP 9000 or Integrity server and/or workstation and an IBM mainframe host in a systems network architecture (SNA) environment. The HP server 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 computer that has its own HP-UX SNAplus2 Link. The client/server configuration permits access to the IBM mainframe from multiple computers on an Ethernet or Token Ring LAN. These computers generally use a single HP 9000 or

Integrity 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.

  • 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)
  • 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.
