Using the SPOOL offload facility for networking

The spool offload facility provides a primitive form of job and SYSOUT transmission. By offloading a subset of jobs at one location and reloading them at another, the jobs will be effectively transmitted from location to location. Although this form of job networking is of limited value with widely separated machines, it is a possible alternative for NJE lines; you can offload spool files on one node, switch or physically transfer the offloaded data to the target JES2 system and use a spool offload receiver to reload the data.

In the following example, the local node offloads all jobs and SYSOUT with the route code SANJOSE. When completed, this tape can be physically sent to the SANJOSE node. At SANJOSE operators can reload the tape, successfully transmitting the jobs.

$P OFFLOAD1

Note: You cannot specify a second-level destination on a route code associated with pre-execution jobs.
