Gain efficiency and reduce reorganization maintenance time
Overview
Optimize IMS database reorganizations
IMS Database Reorganization Expert for z/OS® streamlines IMS database reorganization planning and execution through policy-based automation, using database statistics and centralized policies to determine reorganization needs while providing exception monitoring and alerts that help operators respond more efficiently to database issues.
Features
Reorganizing the IMS database
Utilize high speed database unloading along with additional capabilities not found in the base utilities. Reduce CPU and run time for the unloading of IMS databases. Use an Application Programming Interface that allows certain customer applications to take advantage of the high speed-read engine.
Utilize an easy-to-use front end, one-step procedure for building all IMS indexes, avoiding the need to image copy index data sets. IMS Index Builder can help improve IMS availability and better utilize system resources. Use advanced technology for IMS Index recovery, maintenance and creation. Substantially reduce processing time compared to traditional methods involving image copies of index data sets.
Get high-speed database copy to rapidly back up and recover database data sets with IMS High Performance Image Copy. The tool can automatically take the database offline before making a batch image copy and restarting it after the process. The number of tapes used is reduced by stacking more than one image copy on the same tape. Image backups can be taken automatically during database reorganizations, enabling the use of databases immediately after they are reorganized.
Monitor space utilization to detect and get reports on physical or logical direct pointer problems. These reports pinpoint both the errors and their locations within the IMS database. You can also generate reports to better tune IMS databases and ensure that IMS databases are operational, well-tuned, and free of pointer errors.
Use cases
Improve efficiency across IMS reorganization
Reduce the effort required to manage IMS database reorganizations with policy-driven automation and exception monitoring. Database teams can make informed maintenance decisions, identify issues sooner, and streamline operations to improve efficiency and availability.
Organizations can reduce routine maintenance effort by applying centralized policies that guide conditional reorganizations and exception handling across IMS environments.
Database teams gain clearer insight into maintenance priorities as statistical data and selected reorganization policies determine which databases require attention.
When database exceptions occur, TSO users and z/OS operators receive policy-based notifications, helping teams respond quickly and maintain reliable operations.
