Subject: CPU time and zIIP 

Hello, 

I'm trying to understand the CPU and ECPU times displayed on SDSF and the 
relation to zIIP processing time. 

For example, here is a CICS region running a Java web service. 

*CPU-Time ECPU-Time GCP-Time zIIP-Time zICP-Time zIIP-NTime* 

* 164.42 166.28 90.89 30.21 3.42 71.29* 

Here is a CICS transaction executing in the region to display various ASSB 
fields. 

************ CPU DISPLAY ************* 

*ASCBEJST. . . . . . : 162.20* 

*ASCBSRBT. . . . . . : 2.23* 

*ASSBASST. . . . . . : .00* 

*ASSBPHTM. . . . . . : 1.86* 

*CPU . . . . . . . . : 164.43 (ASCBEJST + ASCBSRBT + ASSBASST)* 

*ECPU. . . . . . . . : 166.29 (ASCBEJST + ASCBSRBT + ASSBPHTM)* 

*ASSB-TIME-ON-ZIIP . : 30.22* 

*ASSB-ZIIP-ENCT. . . : 1.60* 

*ASSB-ZIIP-PHTM. . . : 1.60* 

*ASSB-ASST-TIME-ON-CP: .00* 

The CPU-Time, ECPU-Time, and zIIP-time match (as close as humanly possible 
to switch 3270 emulators and press enter). I was under the assumption that 
ECPU also included time spent on zIIPs, but that must not be true. Is zIIP 
time included in CPU and ECPU? I'm thinking it is not. 


Thank you,
