Improve management by simplifying prefix resolution and update tasks
Overview
Faster IMS prefix resolution
IMS High Performance Prefix Resolution for z/OS resolves and updates database prefixes in a single job step, replacing separate IMS utilities and keeping logical relationships accurate after loads or reorganizations. It streamlines how prefix processing is executed within IMS environments.
Features
Simplifies and speeds prefix processing
IBM IMS HP Prefix Resolution resolves and updates IMS database prefixes involved in logical relationships. Using IMS Prefix Resolution and IMS Prefix Update, it creates the data sets needed to resolve logical relationship pointers quickly and efficiently, helping ensure database integrity and processing accuracy.
Integrated with IMS Index Builder, IMS HP Prefix Resolution also resolves secondary index pointers. Special work files help eliminate I/O and reduce data set allocations, improving performance. Activity reports are automatically created and stored in the IMS Tools Knowledge Base Repository for visibility and auditing.
IMS Prefix Update refreshes database prefixes affected by database loads, reorganizations, or both. It can run independently or alongside IMS HP Prefix Resolution. A special buffer handler enhances update performance, while DBRC reorganization notifications help maintain operational awareness when databases are registered.
IMS HP Prefix Resolution simplifies complex database administration tasks by reducing job steps and eliminating dependence on specific resources. By accelerating prefix-related processing, it helps DBAs work more efficiently while improving system availability and making better use of operational and human resources.
Use cases
Streamline database prefix workflows faster
Simplify database maintenance by streamlining prefix resolution and update activities across logically related databases. Reduce manual processing, eliminate unnecessary intermediate data sets, minimize I/O and storage demands, and accelerate production readiness following database loads and reorganizations.
Help database teams quickly prepare logically related databases for production by ensuring pointer relationships are accurately resolved after database loads or reorganizations, reducing manual effort and improving operational readiness.
Enable administrators to run prefix resolution and prefix update functions together in a single job step, simplifying workflow management, reducing complexity, and improving overall processing efficiency.
Help teams reduce elapsed processing time and resource consumption by using HPPRPIPE data transfer service to remove the need for intermediate work data sets during prefix-related processing tasks.
Support more efficient operations by eliminating the intermediate work data sets DFSURWF2 and DFSURWF3, helping reduce tape handling activities and lowering Direct Access Storage Device (DASD) allocation requirements.
Help organizations reduce or avoid extensive I/O operations, tape handling, and DASD requirements typically associated with prefix resolution and prefix update activities, improving resource utilization and operational efficiency.
