Server is closer in concept to MVS edition, in that there are few "work" stage types and various connectivity stage types. Like MVS edition, server jobs are easy to develop and the environment is tolerably forgiving.

To move to the parallel world there are many more things you need to learn. There are more than 70 stage types (one task, one stage) plus you need to keep in mind key grouping (partitioning), requirements for pre-sorted data, memory usage, and various other technical things. Parallel jobs use strongly typed data and are intolerant of data type and nullability mismatches.

Given that the server to parallel transition lab takes four days as an instructor-led class it's clear that answering that here just isn't going to happen. Parallel jobs require an almost completely different mindset, and this includes forgetting certain server/390 techniques.

Parallel jobs can be executed on Windows, provided that you have version 7.5x2 or version 8.0 or later. Parallel jobs can be executed on clusters and grids, with processing allocated to more than one machine.
