zHISR

Technical Specs

zHISR normalizes sample data between faster zIIP and zAAP engines and slower sub-capacity coprocessors.

When used with z/OS 2.1 systems or later, zHISR supports up to 128 concurrent collections.

zHISR uses resources efficiently and costs little to run. If zIIP specialty engines are available and zHISR is APF authorized, nearly all of zHISR CPU processing is redirected to a zIIP.

While an IBM Z processor (System z10 or later) running z/OS in an LPAR is required to provide the sampling function, the analysis by zHISR is not restricted to these environments. The sample data can be transferred to an older processor or a z/VM guest z/OS with zHISR installed.

zHISR Reports

zHISR analytic reports are based on data created by z/OS Hardware Instrumentation Services (IBM System z10 or better) and stored as UNIX files or z/OS data sets. Reports can be printed, saved to a data set, or exported in CSV format.

Other Features

File system navigation interface: Browse files and even delete them.

Memory display/alter utility: View main storage in the CPU you are logged on to.

z/Architecture instruction speed tester: Determine the relative and actual speed of over 1,000 hardware instructions.

COBOL and Assembler API: Start and stop collections from a program.

Counter data collection and analysis: Collect and analyze counter data provided by the z/Architecture CPU Measurement Facility.
