Check your IMS databases for potential problems early and often
Overview
IMS™ High Performance Pointer Checker for z/OS® monitors space utilization and detects and reports physical or logical direct pointer problems. These reports pinpoint both the errors and their locations within the IMS database. It also generates reports to better tune IMS databases. It can ensure that IMS databases are operational, well-tuned and free of pointer errors.
Enables you to reduce the amount of time spent to diagnose and repair corrupted databases.
Get reports to facilitate system tuning, report space utilization and detect and report problems in primary and secondary indexes.
Repairs VSAM- and OSAM-organized IMS databases that contain pointer or data errors interactively and in batch mode, while reducing the time that the affected database is taken offline.
View entire blocks of data or individual IMS segments and navigate to other segments. Any changes that are made are tracked and can be undone. Dump blocks from the dataset or submit changes to the block data.
Features
Detects and reports problems of direct and other types of pointers. These reports pinpoint both the errors and their locations within IMS databases. It also produces many reports to help in tuning databases such as redundant space in IMS databases.
Produces reports that describe the distribution of root segments in HDAM, HIDAM, PHDAM or PHIDAM databases. It also produces a report that gives summary information about High Availability Large Databases (HALDBs).
Helps analyze the status and historical trend of IMS full-function database datasets which HP Pointer Checker supports. For example, the change in various aspects of IMS full-function database datasets. A historical trend might be the use of space, size and number of database segments, or the size and number of database blocks from the past.
Helps forecast potential space utilization problems of IMS full-function database datasets that HP Pointer Checker supports, and OS datasets including VSAM datasets.
Changes the format of segment data within any existing full-function database including HALDB. Modify databases in ways that exceed the capabilities of the standard IMS utilities. For example, a changing of the hierarchy in a database. When you use DB Segment Restructure, there is no need to write a program to reformat segment data.
Repairs VSAM and OSAM organized IMS databases that contain pointer or data errors. This powerful tool can be run both interactively and in batch mode for VSAM and OSAM datasets.
