memory usage

db2pd -memsets shows below:
Memory Sets:

Ov OvSize
DBMS 0x30000000 131074 33554432 0x89F69C61 0 0
Y 5455872
FMP 0x90000000 131073 245284864 0x0 0 2
N 0
Trace 0xC0000000 131075 140665792 0x89F69C74 0 -1

Why is FMP using more memory than DBMS? Will it provide better
performance if I tune this to allow more for DBMS and less for FMP?

Thanks for your insight.

The FMP is storage reserved for fenced processes. You did not mention
your operating system, but it looks to be UNIX. In a 32-bit memory
model, DB2 will reserve a whole segment if fenced processes are being
used. It looks like db2pd is showing the whole segment size. I just
checked on my system and it looks similiar.
