Xerox DPServer - AIX (also known as EOMS P-Services) Support & Software Leaflet

XPSC-MVS is an MVS host-resident software component of DPServer.
It provides a two-way communication link between the MVS host and
the server-resident DPServer software. XPSC-MVS is a functional
subsystem (FSS) and is written in compliance with the standard
functional subsystem interface (FSI). Integrating XPSC-MVS requires no
modifications to MVS or JES.

XPSC-MVS performs five primary tasks. Each is described below.

Acquire jobs from JES spool. Jobs destined for Xerox printers are
acquired by XPSC-MVS for transmission to DPServer.

Build job ticket. XPSC-MVS scans the job to determine basic
information that DPServer will require, such as job type, priority, and
other information contained in an output statement. XPSC-MVS builds
a job ticket containing this information.

Transmit jobs to DPServer. Following job acquisition from JES and
construction of the job ticket, the data is sent to DPServer via SNA LU
6.2 communications interface. This type of communications interface
supports multiple parallel sessions between DPServer client and server
software, giving you the ability to transmit several jobs simultaneously
while processing requests from DPServer. This is an especially
attractive feature for sites with heavy print volumes.

Ensure data communication integrity. XPSC-MVS has automated error
recovery capability if communication fails during job transmission.
XPSC-MVS utilizes "confirm processing" to synchronize JES
checkpointing.

Accept SMF accounting data from DPServer. Optional accounting
software creates variable-structured System Management Facilities
(SMF) page-printer accounting records. These records are created at
the server, sent to XPSC-MVS at the host, then stored in a host-resident
SMF database for use by host accounting and performance analysis
packages. Again, this information can be received by XPSC-MVS even
if jobs are being actively transmitted to DPServer.

Customers who use AFP data streams but want the quality and features
of Xerox printing systems often choose the Xerox Printer Access
Facility (XPAF) as their solution. XPAF offers a variety of benefits for
customers who print AFP, IBM line mode, and Xerox-formatted data
streams.

XPAF Client software is installed on an MVS host to extend XPAF
benefits. In addition to Xerox printer access, XPAF customers can send
jobs to any DPServer-controlled printer in their enterprise, and have
access to all job, queue, accounting, and resource management
benefits offered by DPServer.
