8. DB2 UDB and the 2.6 kernel

DB2 UDB Version 8.2 can take advantage of a number of performance enhancements introduced in the 2.6 kernel. There is a good paper by Rav Ahuja, Dan Behman and John Keenleyside that goes in depth on the specific enhancements of DB2 UDB V8.2 (see the Section 10 Section); we'll cover a few of the highlights and how to implement them.


Note that these enhancements are for advanced users only. Implement each with care and be sure to thorougly test each change individually before moving on to the next enhancement.
