When I am trying to connect to DB2 using,

db2 connect to <database name> is giving error "DB2 Shared memory insufficient"
So I tried to change(increase ) the kernal values of shmmax, shmmin etc.

Also, when I try to db db2start, now it has started to give errors such as "unresolved symbols"

Pls help urgently with any ideas to resolve this. DB2 version is 8.1 FP7.
