Overview
Figure 1 shows the steps that occur as Download for z/OS transmits
system output from a z/OS® operating
system to InfoPrint Manager, Ricoh ProcessDirector, PSF, or OnDemand servers on other systems.

The following procedure describes the steps that are shown in Figure 1:
- Users submit jobs on a z/OS system,
creating system output on the Job Entry Subsystem (JES) spool in either
a JES2 or JES3 environment. The job submitters can specify job control
language (JCL) parameters that direct the output data sets to Download for z/OS and
also to a remote (receiving) system. The data sets can contain any
type of data stream.
- Download for z/OS, running as a JES2 or JES3 functional
subsystem application (FSA), selects output data sets from the
JES spool according to installation-defined JES work-selection criteria,
such as class, that correspond to JCL parameters that are specified
by the job submitters. Several Download for z/OS FSAs can
run at the same time to process a high volume of data.
- Download for z/OS transmits the output data sets, with print options
that include the JCL parameters, to remote systems in the Internet
Protocol network. Download for z/OS uses routing information that is specified
by the installation in a routing-control data set to determine the
remote system that is to receive the data. The routing information
associates JCL parameters that are specified by the job submitter
(output class, destination, and form name) with the IP addresses or
host names of remote systems and receiving servers.
- Remote servers receive the data sets into file systems.
These products provide servers to receive data from Download for z/OS: InfoPrint Manager, Ricoh ProcessDirector, PSF, and OnDemand.
The AFP Download Plus feature of PSF is required to enable PSF as a remote server
for Download for z/OS. Several servers can run simultaneously on one system
to handle large amounts of transmitted data.
- The remote servers process the received files according
to instructions coded by the installation in a shell or Perl script
or exit routine.
