IMS High Performance Prefix
|
IBM IMS High Performance Prefix Resolution is used in maintaining all logically related IMS databases and is required after the databases are loaded or reorganized. IBM IMS High Performance Prefix Resolution, Version 3.1, enables you to resolve and update prefixes of IMS databases involved in logical relationships as a single job step.
A data transfer service called HPPRPIPE (eliminating Work File 2 (WF2) and Work File 3 (WF3) data sets) avoids much of the I/O, tape handling, and DASD requirements associated with prefix resolution and prefix update. This version of IMS HP Prefix Resolution supports IMS Parallel Reorganization for z/OS, Version 3.1 single job step execution of database reorganization, prefix resolution, and prefix update tasks.
Also included with this latest version of IMS High Performance Prefix Resolution, Version 3.1, is the capability to perform the Prefix Resolution function and the Prefix Update function as replacements for the IMS Prefix Resolution Utility or the IMS Prefix Update Utility. Using these functions over the existing base IMS Utilities provides even more performance improvements when performing this type of database maintenance.
