Easy-to-use, one-step procedure for building all IMS indexes
Streamline index creation, maintenance and recovery
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.
Provides advanced technology for IMS Index recovery, maintenance and creation.
Substantially reduces processing time compared to traditional methods.
Eliminates the need to image copy index data sets.
Provides easy-to-use front end for setup.
Features
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.
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.
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.
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.
IMS Index Builder generates statistical reports, which are stored in the IMS Tool Knowledge Base (ITKB) repository for centralized viewing and historical analysis.
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.
