Overview:
Easy-to-use, one-step procedure for building all IMS indexes
IMS™ Index Builder for z/OS® simplifies rebuilding IMS primary and secondary indexes, as well as HALDB Indirect List Data Sets (ILDS). It uses advanced sorting and parallel processing to streamline index creation, reorganization, maintenance, and recovery. This tool can create multiple indexes in one job step and rebuilds IMS indexes without the traditional unload and reload processes.
Highlights
- Rebuilds IMS primary and secondary indexes and HALDB Indirect List Data Sets (ILDS), removing the need for index image copies
- Creates multiple IMS indexes in a single job step
- Integrates seamlessly with IMS High Performance tools to rebuild indexes during reorganization and recovery
Features:
Minimizes elapsed time and maximizes availability
IMS™ Index Builder for z/OS® minimizes index creation elapsed time in building one or more indexes and maximizes high database availability. It issues IMS commands internally to take IMS databases offline and online for the minimal amount of time necessary to ensure there are no updates while the IMS indexes are being rebuilt.
Speeds up work with parallel processes
IMS Index Builder uses a number of parallel sort algorithms including buffered sorts to reduce I/O activity and improve performance. These sophisticated algorithms help ensure the rebuilding of an IMS index is faster than the process of image copying and recovering the IMS index.
Supports various databases
IMS Index Builder supports both non-partitioned and partitioned databases. It scans supported HD and HISAM databases to build primary and secondary indexes and creates new secondary index databases for non-partitioned systems. It also creates indexes for HDAM, HIDAM, HISAM, PHDAM and PHIDAM databases.
Integrated with many IMS database administration processes
When an IMS database is reorganized or recovered, IMS Index Builder rebuilds the indexes. Integrated with IMS High Performance Prefix Resolution, it extracts data to resolve database prefixes for logical relationships. It's part of three IBM® IMS Solutions: IMS Database Solution Pack, IMS Database Utility Solution and IMS Recovery Solution Pack.
Provides statistical reports
IMS Index Builder generates statistical reports, which are stored in the IMS Tool Knowledge Base (ITKB) repository for centralized viewing and historical analysis.
Offers advanced architecture and components
IMS Index Builder invokes its driver by the job-step executable, which initiates the MAS, analyzes input, processes database control tables and attaches common services. In the final step, multiple SAS are initiated to perform scans and sorts in parallel, indexes are loaded and DBRC registration is completed.
