Job Optimizer Pipes overview

The Job Optimizer Pipes component establishes an in-memory pipe between one or more jobs that create the data (writers), and one or more jobs that read the data (readers).

By using a pipe, the reader can access a block as soon as the block is written. The writer and reader jobs or steps can execute on the same image or on another image in the Parallel Sysplex.

Data that is passed through a pipe exists only until read by the readers. In some situations, a physical copy of the data is required for future use or for backup purposes. To answer this need, Job Optimizer Pipes can write the data to a physical file on disk or tape. This functionality enables writer and reader jobs to execute concurrently, while still preserving a hardcopy of the data.

The following figure shows two data-dependent jobs executing in parallel: the data is concurrently piped through memory and copied to disk.
