John, I'm passing this to our CICS sysprogs to see if it's something they can

sequentially. However, the amount of inserts (2/5ths) seem to point to what I

Hi folks,
wondered if anyone can help me understand some FICON performance issues?
I'm seeing huge DISC times (58 - 70%) for a device on LCU 6571. The manual
says that I can get an good estimate of the MB/SSCH by taking the MB/SEC
from the IOQ activity report and dividing them by the Total

Just been told by IBM that XRC device blocking can be displayed in
different places on different vendor hardware.
IE
HDS show device blocking in DISC time
IBM ESS show it in IOSQ time.
If using write pacing, then it's in DISC time for both HDS and IBM.

Hi folks,
Wondered if anyone could give a difinitive answer to where RMF would show
delays caused by XRC device blocking.
Would it be in the DISC time, or the PEND time. Or maybe somewhere else
altogether.
Much appreciated.

Paolo,
Many thanks again.
I'm currently in a huge argument with the performance team who insist that
XRC device blocking is shown in DISC time. IOSQ time sounds more plausible
as the CU wouldn't reply to a CMR if the device was being actively blocked
so a SSCH wouldn't be issued?
Is this
Bill,
My understanding (could be completely wrong, which is why I'm asking the
question) is
XRC will block a primary volume for a certain amount of time (the time the
device is blocked is dependent on the vendor) if XRC can't keep up with the
records that need to be written to the
Many thanks for that Derrick,
We too have started looking at write pacing as we too are a multi vendor
shop. We have found that HDS boxes only add 0.1 second for device blocking
whereas our sharks add a whole second. We still haven't implemented write
pacing so I guess that means our blocking

Tom,
We've not had performance problems for the dataset, just the occasional
hiccup when they get allocated to a hot volume which then exceeds the
x'500' threshold in XRC. The primary concern is that XRC doesn't block the
volume so striping would just mean we have to DNB more volumes wouldn't
Tom,
First off, can you point dynamic allocations to a specific SC? - If so I'm
sorted as we already have a particular SG that has every volume set to
DONOTBLOCK. If you can specify SC for dynamic alloc's then I have an SC
that points to this SG.
The problem is, these datasets do require, and
