How do people running earlier CF levels do their sizing? I did not see
an entry field for the CF level...
That's an exercise left to the reader:
>From http://www-304.ibm.com/systems/support/z/cfsizer/ :
"CFSizer uses your input to calculate the number of structure objects the
structure must contain, based on algorithms provided by the structure owners
that model their use of the structure. Using these results and structure
attribute information provided by the structure owners, CFSIZER THEN SUBMITS
A CALCULATION REQUEST TO A COUPLING FACILITY, USING THE IXLCSP INTERFACE.
The coupling facility itself calculates the structure size required to
accommodate the specified input. Structure sizes therefore correspond to the
CFLEVEL installed on the coupling facility that performs the calculations.
I guess, as long as the "rule" holds true that higher CF levels nearly
always require the same or more storage, a "lazy" sysprog can't go wrong
using the values provided by CFSIZER, so long as s/he doesn't run out of
storage. In a short-on-storage situation, closer scrutiny would be
advisable.
