Martin,
We develop a product that intercepts SMF records in real-time and generates a
DataBase in Open Platform. This Data can be used to generate reports and
graphics dynamically.

Subchannel busy (as opposed to busy CONDITIONS) is estimated from request
rate and service time multiplied together.
I think we'd all like to know the purpose of this, though.
Cheers, Martin

Colin,
Thank you very much for your time.I'll take a closer look at these SMF
fields.
Best Regards

Hi,
CF level Local Coupling Facility Data Section
24 18 R744FPBC 8 l_float Number of times coupling facility requests fail
due to path busy.
You get data for each structure
For the Structures you get the different sorts of requests
92 5C R744SSRC 8 l_float Count of number of times for synchronous requests
44 R744SARC 8 l_float The total number of operations executed
asynchronously at the
coupling facility.
R744SATM 8 binary Summed service time for asynchronous requests in
microseconds
54 R744SASQ 8 binary Summed squares of service time for asynchronous
requests.
so you can calculate your own average and standard deviation from these.
and add up the total number of sync/asnyc requests to get a figure for
the
CF as a whole
regards
Colin
