How to define private data

If you want access to a table space named NOSHARE limited only to DB2C, you could assign NOSHARE to a previously unused buffer pool, such as BP25, using the ALTER TABLESPACE statement.

Do not define a group buffer pool that corresponds to BP25, and assign BP25 a size of zero on any other member of the group. This prevents the other members of the group from attempting to use this buffer pool and therefore prevents the other members from accessing table space NOSHARE.
