Description Eugene Chan

This is related to bug 88645

In TPTP 3.3 and 4.0. Methold Level CPU time is avilable for collection, and
Method Statistics view and Method Invocation table provide option to show the
values as an extra column of the view/table.

There are limtation of the feature in the following platform: (extract from bug
88645)

The behavior is limited or problematic on AIX and Solaris:

Aix - 1.4.1 IBM (ca1411-20030930) : 
On Aix 5.1, cpu usage reporting requires that the environment 
variable "AIXTHREAD_ENRUSG=ON" be exported. There is no support for cpu usage 
reporting on AIX 4.3. 

Solaris - 1.4.1 Hotspot (1.4.1_06-b01) :
On Solaris, cpu usage reporting is suspect at this time. It appears that it may 
be reporting elapsed time instead of cpu time. This is under investigation with 
Hursley presently prior to issuing a pmr.

This defect looks like it would be appropriate for the readme. Applies to TPTP 
3.3 and 4.0 -  Monitoring and Anlyzing Performance. Suggested wording:

Release Note:

Method level CPU time statistics limitations on AIX and Solaris

In TPTP 3.0 and 4.0, method level CPU time statistics are available for 
collection. Optionally, you can view method level CPU time statistics in an 
additional column in the Method Statistics view or Method Invocation table. 
Platform limitations for this feature are as follows:

There is no support for method level CPU time statistics reporting on AIX 4.3. 

On Aix Version 5.1, method level CPU time statistics reporting requires that 
the environment variable "AIXTHREAD_ENRUSG=ON" be exported. 

The method level CPU time statistics feature is currently not supported on 
Solaris.
