What IMS High Performance Load can do for your business

IMS™ High Performance Load for z/OS® reduces CPU and runtime for certain applications and the loading of IMS databases. It analyzes database performance and prepares reports that contain statistics about space use and segment pointers. It creates the indirect list data set (ILDS) of a High Availability Large Database (HALDB) that is compatible with the one created by IMS standard IMS HD Reorganization Reload utility.

IMS High Performance Load consists of the IMS HP Load utility, the Physical Sequence Sort for Reload utility and the Bitmap Resetter utility. It also provides the load application programming interface (Load API).

IMS High Performance Load for z/OS

Achieve high performance

IMS High Performance Load for z/OS is designed to provide high-performance processing by default parameter settings. You can get optimized performance on each reorganization job.

Get greater ease of use

Avoid writing DD statements for a database data set because IMS HP Load can dynamically allocate a database data set for a full-function database and HALDB.

Acquire more data compatibility

Data that are created by IMS HP Load, such as the DFSURWF data set, are compatible with IMS standard utilities.

Save time

IMS HP Load does not require HALDB partition data set initialization before reloading. For partitions not populated by any segment during reload, IMS HP Load initializes the partition data set.

Gather more data

IMS HP Load provides statistical data that is needed for database tuning tasks and space analysis tasks.

Gain flexibility

IMS HP Load accepts multiple file input formats and supports compressed formats.
