How to create Buffer Pool in Database dedicated only for ONE BIG table?

Question

I have table TICKET with 400K records in database (DB2).

I wish to create one huge buffer pool which will be dedicated only to this one big table for faster response. What are the steps to do it?

Also at the moment I have one Buffer Pool which coovers whole Table space with all the tables (about 200) in database! what will happen then with that my specific table in that old firstly created buffer pool? should that table stay in first buffer pool or how to remove from that buffer pool?? Also are there some risks for this action???

Thank you
