Good evening (at least here in Europe).
The German 'Computerwoche' has a couple of interesting articles this week.
IBM announced the Power 6 processor.

Thank you Birger for the link to the new z/OS Hot Topics newsletter.
I have a question concerning the byte range lock manager article.
After reading about the various evolutions of the BRLM (single environment,
shared, recovery considerations within a sysplex), I was wondering why the

History:

I do not believe IBM changed the name, again.

Hi,
I am just starting to get to grips with the RMF Spreadsheet Reporter.
I need to do some analysis of some historical data that was created on a zOS
1.4 system on my current zOS 1.6 system.
However, the RMF Post Processor is complaining about differing levels of Code &

The fact that ickdsf cannot clip the volser is because the hardware knows
that this secondary disk is part of a suspended pair .
When you suspend , ickdsf will tell you

John,
Not actually true. There is a bitmap merge as part of the resynch.

This part is well documented. Issue:

Run z/os.e on a very small CPU with upgrade on demand at your BR site.
The backup steps don't need a lot of CPU power, and z/os.e is cheap.
Very cheap. Once you pull your DR trigger, upgrade the box and start
recovering your LPARS. The z/os.e LPAR can remain active to assist as a

In LPAR mode, if a Logical Processor is not dispatched by PR/SM then it does
not accumulate wait time even though it is actually waiting. This means that
MVS % Busy is greater than actual time that LP within the LPAR were
dispatched by PR/SM and busy.
LPAR busy is the right number, th

Never heard of it, and in our business we certainly would have.
Don't forget that 3390-27 and -54 are fictional names, not official
ones. Although IBM occasi

To all who have helped with our research into GDPS with SRDF/A, THANKS!
What we've found is that virtually no one is running a GDPS with syncronous
data replication, and we fould only one instance of active data sharing across
sites.
