Peter
Are you specifically interested in finding shared pool freespace
fragmentation ? Shared pool freespace is maintained in multiple
freelists and this script by Steve Adams shows a good picture of shared
pool freespace fragmentation. BTW, Does your database have shared pool
latch contention ?

Subject: Measuring shared pool fragmentation
Is there a way do measure the amount of shared pool fragmentation? I
would be looking for metrics such as the largest available chunk of
memory, number of fragments, average size of memory fragments ...
thanks,
Peter Schauss
