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.
