I found the APAR, it is PK03680.  I put a posting on the DB2 list, where a
number of DB2 development folks post, to see if they have any insight. I
will summarize and forward any comments.

It is sort of documented that DB2 doesn't honour IEFUSI - not spelled out in
brutal clarity and worded very carefully, but the DB2 apar says that they
don't honour memlimits below 4TB. So I don't see that reporting a 'defect'
has any chance of getting this fixed, especially as even here on ibm-main a
lot of people argue that the storage isn't really getmained - until a bug
kills the system.

I don't consider what DB2 does right and I think that their setting is
asinine given what we now learned about the possible paging config. So the
only chance I see is submitting an RCF that the Extended addressability
guide is clearly wrong because DB2 doesn't play by the rules outlined there.
My guess is that IBM will change the Ext Addr Guide. :-(

So I better spend my time writing my monitor program to get alerted once
things go downhill than spend the energy to argue with IBM. I'll leave that
to the SHARE memebrs - maybe a topic for the next SHARE.

Best regards, Barbara
