This is a pair of questions asked by Radoslaw Skorupka in the RACF-L list as a
musing resulting from a question being asked about FFST and SAF.
It seems pointless to have the discussion continued in the RACF-L list which
was actually the wrong place to be asking the original question anyhow.

Hi Radoslaw. To edit individual members you could use the System z/OS
perspective within (free) IBM CICS Explorer 1.0.1.0, giving you a plain text
editor. From the opposite end, if you setup the (free) ISPF wsa you can use
ISPF option 2 to fire up a PC editor of your choice.

Using Jumbo Frames usually increases throughput by increasing link
utilization.
I must be missing something here. If by improving the efficiency as defined in
http://en.wikipedia.org/wiki/Ethernet_frame
you get more throughput, why is that a bad thing? It might even solve the

I didn't say it was a bad thing, I was actually trying to express that they
were probably already using jumbo frames if they were getting that kind of
throughput. Bad choice of words.

I probably shouldn't get in between you two exchanging social niceties, but I
would be most surprised if *anyone* (IBM included) has used FFST in years.
Have a look at the changes section of the manual for example.
I thought it was a good idea when I first saw it, but it shriveled away years
ago.

Network traffic is not a good metric for 'throughput' in my opinion.
'Throughput' might best be expressed in the time needed to move a data byte
end to end. A 'network' byte could be data, overhead, or the silence between
packets. And the time to move a data byte end to end doubles for each

I would say that if it were not for MSU based billing, everybody would
be happy with just getting a new CP and having the excess just sitting
around. In this case, the upgrade cost would only be the cost of a CP.

You can get an average and maximum for a given time interval from RMF. Correct

Majorly, DB2 V10 offloads more work to ZiiPs. If you are on some sort of usage
