Get high-speed database unloading with added capabilities
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.
Benefits
| Save time | Substantially reduces the time and resources needed to unload databases. |
| Use the high speed read engine | Provides the high-performance High Speed Sequential Retrieval (HSSR) Engine. The unload utilities and the application programming interface (API) use the HSSR Engine to provide fast retrieval of data. |
| Take advantage of more options | 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. |
| Unload various data sets | Unloads HALDB, HDAM, HIDAM, HISAM, and SHISAM databases – and even broken data sets. |
| Improve tuning | Includes various statistical reports for better tuning. |
Learn about IMS High Performance Unload for z/OS
| Why use IMS High Performance Unload for z/OS? | 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. |
| Features two unload utilities and an API | IMS High Performance Unload includes two unload utilities, FABHURG1 and FABHFSU that provide high speed unloading capability. It also includes an application programming interface (API) for DL/I application programs that use GN calls. |
| Works well with other IMS tools | 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. |
| Generates statistical reports | 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. |
