Performance Toolkit for VM - APAR VM64819
The subject APAR provides updates and changes to the FL540 and FL610 levels of Performance Toolkit. The primary sources of these updates are from problems uncovered by internal IBM testing and from running Performance Toolkit for VM on internal IBM z/VM systems. The tables below contains a list of the internal problem numbers (column labeled "PITS") and an abstract of each problem corrected by way of this APAR.

Product Enhancements
The following table documents enhancements made to Performance Toolkit as part of this APAR
| PITS | Abstract |
| FC00640 |
PERFKIT does not handle Gigabyte values, esp. with processor storage
(support for representation of any 64-bit number) |
| FC01098 |
FCX126 needs load by processor type
(support for CP/IFL/ICF/ZAAP/ZIIP CPU types on the LPAR report) |
| FC01146 |
Color/highlighting is turned off for menu screen headers under web
(all the color/highlighting attributes are handled properly for web) |
| FC01180 | Moving total counters in FCXTRN to 64 bit |
| FC01224 |
Usability neither report names nor numbers appear on web screens
(string FCXnnn is prefixed to the report name on the web) |
| FC01237 |
Cursor should be automatically inserted in the command line under web
(when the 'Command' button is pressed then the cursor will be placed in the input field) |
| FC01249 |
Divide exception (PRG009) handler should be added to Perfkit
(any division inside Perfkit code that would have resulted in a PRG009 exception, will just lead to an informational message "FCXxxx199A Divide exception at...", and normal operation will continue with the quotient set to the max possible value) |
| FC01279 |
Too few decimal digits on user T/V ratio
(on the USER report "T/V ratio" format was changed from nn.n to nn.nn) |
| FC01320 |
Consider changing default 00:00 MONCOLL RESET for PERFKIT BATCH
(multi-day MONDATA files support) |
