SPEAKERS: Tom Glaser (AT&T)

Tired of monitoring for the "status quo?" Are you on a scavenger hunt looking for answers to your problems? Do you wish the real or potential problems would just bubble up to the top and show themselves to you? We are all fascinated in how other companies monitor and tune their subsystems. Come see how AT&T uses its tools of choice to monitor more than 225 subsystems. This presentation will not only focus on how we use Query Monitor to find that single SQL statement consuming all our CPU, well also show you how we solve some of the more common problems/questions, like who stopped our database or what value was used in your host variable? How we integrate SQL Performance Analyzer into our environments, and how Omegamon XE for DB2 PE is used to look at the entire ball-field.

EXP. LEVEL: Intermediate


Why does AT&T monitor it's subsystems? We'll explore why a monitor is needed and review the various monitors available to us. What's different about a query monitor, versus a subsystem monitor.

We'll look closer at how Query Monitor(QM) is being used at AT&T, why its used by everyone; programmers/application DBAs, to DB2 Systems Support. We'll explore many built-in features; looking at the SQL/CA, DB2 Commands & displaying host variables

AT&T uses SQL/PA to perform its Explains...well show you why. How this tool interfaces with Query Monitor and Omegamon for DB2.

Need to start an SQL trace? Omegamon for DB2 is the tool AT&T uses, well show you why? We'll look inside the Dynamic Cache, visit Omegamon on the web, how we set up our performance database, and home grown tools used to interface with it.

Come see how AT&T is using Query Monitor, SQL/PA and Omegamon XE for DB2/PE to monitor more than 225 subsystems. What home grown tools have we built to track our subsystems. What functions can benefit the DBAs, applications, and systems support.
