Get high-speed database unloadingÂ
IMS™ High Performance Unload for z/OS® provides high speed unloading of IMS databases and improves the performance of IMS data retrieval application programs by using the unload application programming interface (API). It saves you time and money by reducing the CPU and elapsed time that is required to unload IMS databases and to run IMS data retrieval application programs. It also provides powerful functions such as the ability to continue processing after a pointer error, a user exit facility and various unloaded record formats.
Â
Substantially reduces the time and resources needed to unload databases.
Provides the high-performance High Speed Sequential Retrieval (HSSR) Engine. The unload utilities and the API use the HSSR Engine to provide fast retrieval of data.
Offers user control and exit capabilities not found in the base utility, such as unloading compressed data without decompression overhead and a user exit facility for added processing of each segment.
Unloads HALDB, HDAM, HIDAM, HISAM and SHISAM databases—and even broken data sets.
Includes various statistical reports for better tuning.
Features
As processing volumes increase, more work needs to be done in a shorter time due to shrinking batch windows. IMS High Performance Unload for z/OS saves you time and money by reducing the CPU and elapsed time that is required to unload IMS databases and to run IMS data retrieval application programs.
IMS High Performance Unload includes two unload utilities, FABHURG1 and FABHFSU that provide high speed unloading capability. It also includes an API for DL/I application programs that use GN calls.
IMS High Performance Unload is designed for use with IMS Database Reorganization Expert for z/OS, IMS Online Reorganization Facility for z/OS and other high-performance IMS Tools products to provide the most efficient and powerful end-to-end solution for IMS database reorganization.
IMS High Performance Unload generates statistical reports that are used during IMS database reorganization to help determine when a reorganization is needed. The reports can also be used to measure the quality of the HDAM and PHDAM randomizing routines.
