Introduction:

The CWAITS command displays a degradation analysis graph to summarize the time spent by CICS on various execution and wait reasons. 

A sample of the display is:

 

------------------------------------------------------------------------

Cmd Jobname  Resource                                                Average      Pct% .

___ CICSname Life time of transaction                          0.008808     100%  

___ .                CPU time used by transaction                0.000798     100%  

.....

___ .              Wait for dispatch - QR TCB                     0.000048         1%  

___ .              SYSVIEW global user exit monitor time     0.000450         5%  

___ .              SYSVIEW global user exit cpu time      0.000261       33%  

 

 

One of the resources displayed is 'SYSVIEW global user exit cpu time'

 

Question:

How is "SYSVIEW global user exit cpu time" calculated?

 

Answer:

SYSVIEW can use several CICS global user exits to monitor CICS transactions.

SYSVIEW measures the elapsed time and CPU time between the point where SYSVIEW gains

 control in the exit until SYSVIEW gives up control in the exit.
