Overview:
IMS™ is IBM’s premier transaction and hierarchical database management system. IMS was designed for high availability, superior performance, growth and capacity, and full database integrity. The ability to operate and manage this highly complex IMS system and database environment determines the Total Cost of Operation (TCO). The IBM® IMS Tools lowers TCO by equipping IMS system programmers and IMS database administrators (DBAs) with the facilities they need to effectively monitor and manage this mission-critical environment. The IBM IMS Tools provide automation, validation, and auditing of all database and transaction management activities.
Highlights
- Automates the complex tasks involved in performing IMS database reorganization
- Uses space management analytics to determine when IMS databases should be reorganized
- Executes IMS database reorganization using parallel processing to achieve high performance and reduced IMS database unavailability
Features:
Reorganizing the IMS database
IMS High Performance Unload
IMS High Performance Unload extracts the data from the input database and passes it to IMS High Performance Load through a data “pipe,” reducing the number of I/Os because the need for an unload file is eliminated.
IMS Index Builder
IMS Index Builder enables index information to be passed from the reload task to the index-building task for processing through another data pipe. IMS Index Builder creates indexes for the reorganized database during the reorganization process.
IMS High Performance Image Copy
With IMS High Performance Image Copy, database blocks can be passed directly from the reload task to an image copy task for processing. Image copy datasets can be created for the reorganized database and the rebuilt indexes during the reorganization process.
IMS High Performance Pointer Checker
IMS High Performance Pointer Checker allows HASH pointer checking during the image copy processing. The IMS Parallel Reorganization Driver (IPR Driver) schedules and controls the tasks of unload, reload, index-building and image copy in a single job step. As these tasks are handled by the five IBM high-performance tools and intermediate data is passed between subtasks without physical I/Os, reorganization is completed rapidly.
