Issue/Introduction

My questions are:

1) what is the difference between TASSYTI & TASTIMSY vs, TASUSTI & TASTIMUS?

2) currently i report, track, & trend only TASTIMSY & TASTIMUS, and we saw only a small difference before and after implementing ZIIP, so how should i incorporate ZIIP cpu figures from SMF to measure performance?

Environment

Release:
Component: IDMS

Resolution

The difference is one is in 10,000ths of a second and the other is in TOD format.
The TOD format is derived using a STCKE instruction.

See the IBM principals of operations manual for a complete description of the STCKE and what the value represents.
