In addition to the end-of-session statistics printed by every Adabas nucleus, the statistics for a cluster nucleus also include global cache and lock statistics.
If you are running the selectable unit Adabas Online System (AOS), all of the statistics shown in the following sample output are displayed.
If you are running only the demo version of AOS delivered with Adabas, the statistics displayed are limited as follows:
| Section | Displays statistics only for... |
|---|---|
| Global Cache Statistics | totals, DS, and NI |
| Global Lock Statistics | buffer flush, hold ISN, new data RABN, and global update command sync locks |
