Large volume processing

Workload Automation Programming Language is a REXX based tool, with the processing engine designed for ease of use and flexibility. Hence, for very large scale processes PIF programming or other utilities might provide more efficient solutions, as described hereafter.

To update the Application Description (AD), Operator Instructions (OI) or Run Cycle Groups (RG), the EQQYLTOP batch program is the most efficient tool to use. For all other types of database objects, you can use Workload Automation Programming Language.

To extract large amounts of Batch Loader data (AD, OI, RG) or data from the current plan, the Batch Command Interface Tool is the most efficient tool to use.

For complex large volume processing, or repeated processing, use Workload Automation Programming Language to produce and test a prototype program, which you can run with OPTIONS MSGLEVEL(5) TRACE(3) to show each required PIF call, the arguments used, and the segments and records extracted. You can then use this information to design a PIF program to perform the requested function, without the Workload Automation Programming Language overheads. For a description about how to write a PIF program in various languages, the SEQQSAMP library provides you with some samples.
