DB2 V8 32-bits and 64-bits instance

What's the difference between DB2V8 32-bits and 64-bits instance on
AIX? and I am confused the relationship between DB2 32/64-bits
instance and 32/64-bits AIX?
Maybe it is a simple question. Please advise. Thanks so much.

James,

64bit OS/hardware can run 32bit applications.
So a 32bit instance is a 32bit version of DB2 with all the restrictions
associated with it (e.g. limited buffer pool, shared memory, etc,
etc...) even when running on a 64bit AIX.

Does that help or am I stating the obvious?

Do you mean besides the shared memory restrictions that a 32 bit
instance has that a 64 bit instance doesn't?
