General information about the host server program
The host server program is a single load module that can be purchased as a feature of PSF for z/OS. Once started, the host server program runs continuously. It waits for connection requests from one or more InfoPrint Manager servers and creates a subtask to process each request. When a request is completely processed, the subtask ends. The host server program creates a new subtask for each request.
You can run the host server program in a startable address space or as a job managed by a host initiator.
The InfoPrint Manager server sends AFP data to the host server program that places the AFP data in a SYSOUT data set. When the host server program allocates the SYSOUT data set, it accepts the default spool space allocation for the SYSOUT class definition in JES.
The host server program associates attributes passed by the InfoPrint Manager server with the SYSOUT data set. These attributes are similar to JCL OUTPUT statement parameters. They include:
- The host server program requires a
5Acontrol character to precede each AFP statement in the AFP data sent by the InfoPrint Manager server.
- The InfoPrint Manager server always passes a value for the DATACK parameter with each uploaded file. This DATACK value overrides the DATACK parameter in the PSF for z/OS PRINTDEV statement.
