Just a quick note to inform my readers that I will be conducting a webinar tomorrow - Wednesday, April 18, 2007 - on the topic of Change Control for DB2 Access Path Selection. The session will start at 10:30 Central time and will last about an hour. To register, click on the link above.
Here is a short description of what I'll discuss: Most changes are strictly controlled in the mainframe environment. But that is not the case for DB2 access paths. When we BIND or REBIND a program, DB2 formulates access paths “on the fly” and we do not have any control over what DB2 creates for us. This lack of control over changes can cause unpredictable performance.
This webinar is in the past and can no longer be viewed.
