You definetly hit one one of the things, the number of days.  Somehow ours got 
set to 999.  But in only went back to 5/29/98, when we upgraded OS.  However 
the IBM'er also was saying that if you jump operating system releases that 
sometimes it won't delete any data, new release or old release, until you 
remove some of the data that was prior to the new release that you are running. 
 Something about different data formats.  We had to step through some hoops to 
delete that data.

Re PM/400 - QMPGDATA library

4GB !!!

Sounds like someone has the parameters for PM/400 set to some
ridiculously high value for days to keep performance data.

                        Work with PM/400 Customization            
                                                                  
Type changes, press Enter.                                 System:
                                                                  
      High priority limit  . . . . . . . . .   20                 
                                                                  
                                               S M T W T F S      
      Trending days  . . . . . . . . . . . .     Y Y Y Y Y        
                                                                  
      First shift  . . . . . . . . . . . . .    8:00    - 18:00   
      Second shift . . . . . . . . . . . . .   18:00    -  8:00   
                                                                  
      Performance data library . . . . . . .   QMPGDATA           
                                                                  
      Performance data purge days  . . . . .    10                


GO QMPGLIB/PM400  option 6

Reduce Performance Data Purge Days to something reasonable.
PM/400 itself can live with one day, as it purges the data every night
at midnight.
The only reason to keep the data longer is if you want to run
Performance Tool reports or Performance Modelling using the full
unfiltered data in QMPGDATA.  I occasionally run performance tool
reports a week after the data was gathered, so set it for 10 days.
Either you have a high number of days, or a VERY busy machine with a ton
of performance data.  Either way, reduce the number of days.
