It's called "LBAC" (Label Based Access Control) and is delivered as an
optional feature called "Advanced Access Control Feature".
There is a Redbook "DB2 Security and Compliance Solutions for Linux, UNIX
and Windows" that also covers LBAC, but it is for 9.5:

DeveloperWorks has a 2-part tutorial on LBAC (also 9.5 based) here:

(registration needed for full access)
The Infocenter for DB2 9.7 contains a chapter on DB2's security model,
including LBAC:

Thanks.
Do you know if there is an additional license fee for this feature?
Yes, the advanced access control feature is an extra-cost feature - and
it is only available if you have ESE.
