Program number: 5655-E06
IBM IMS High Performance Prefix Resolution for z/OS, V3
The IBM IMS High Performance Prefix Resolution for z/OS tool:
Enables you to resolve and update prefixes of IMS databases involved in logical relationships as a single job step.
Uses the HPPRPIPE data transfer service to eliminate the intermediate Work File 2 (WF2) and Work File 3 (WF3) data sets.
Helps you avoid much of the I/O, tape handling, and DASD requirements that are often associated with prefix resolution and prefix update.
Executes the prefix resolution and prefix update functions as replacements for the IMS Prefix Resolution and IMS Prefix Update utilities.
Supports IMS Parallel Reorganization for z/OS, V3 single job step execution of database reorganization, prefix resolution, and prefix update tasks.
Program number: 5655-M27
IBM IMS High Performance Pointer Checker for z/OS, V2
The IBM IMS High Performance Pointer Checker for z/OS:
Enables you to analyze corrupt databases quickly and reduce the amount of time spent to diagnose and repair them.
Generates reports that facilitate system tuning, report space utilization, and detect and report problems in primary and secondary indexes.
Provides the ability to set several new thresholds, including available extents, CA and CI splits, and database and data set last extents.
Has significant improvements in performance to Full Checking capabilities: improved usability with simplified setup and operation; parallel processing of databases; and improved reporting.
When the IMS High Performance Pointer Checker is used in conjunction with the IMS Database Repair Facility, the tools work together to help detect and correct database errors and repair them with a minimum of downtime.

Eliminates the need to image copy indexes.
Provides an ISPF front end for easy JCL generation.
Creates a separate address space for sorting index records.
Recognizes index records that have duplicate keys and writes the duplicate keys to a SYSOUT data set.
