Rob,
Do you only keep two days of management collection objects? (I really like
to see folks keep at least 14 days worth, 21 days are better) It sounds
like collection services is set up to put the management collection objects
in QMPGDATA rather than QPFRDATA. Also clearly you don't create the
performance data very often or at all. (a good thing if you don't need the
files for a performance investigation)
QPFR is the performance tools licensed program product library, I would not
mess with it.
QPFRDATA: I would not clear since that's really an IBM supplied library.
QMPGDATA could be removed as long as collection services is updated to use
QPFRDATA.
QPFRD71001 is a library of user creation not by IBM/MPG so clobber away if
you wish.

Subject: Performance data
I have these libraries on my system:
QMPGDATA
QPFR
QPFRDATA
QPFRD71001
QPFR has a bunch of programs in it.
QPFRDATA only has 4 files in it with a blank last used date. Change date is
from our system migration.
QPFRD71001 only has a few files in it created back in 09 or 10 with blank
last used dates and change dates from our system migration. Assuming this
is performance data prior to when that system upgraded to 7.1.
QMPGDATA has numerous data queues in it created back in 09 or 10, all with
blank last used dates and the change dates are from our system migration.
It does, however, have several active files. Along with those two huge
active *MGTCOL's.
I realize that everyone's system may differ. Our systems that have been
around forever have an active QMPGDATA and dormant QPFRD* libraries. Our
systems that started fresh with 7.2 do not have QMPGDATA and have an active
QPFRDATA.
Should I delete QPFRD71001 (been a long time)?
Should I clear QPFRDATA on the top system?
Should I delete the data queues from QMPGDATA that were created 2 or more
years ago and have blank last used dates?
