For this last podcast of the series we decided to do something we've been joking about doing for some time, giving ten tips and doing a shot with every one. Do NOT TRY THIS AT HOME! Just sit back and listen to us try to get through this while getting some good performance tips. The music beds include Hit me with Your Best Shot by Pat Benatar, Shot in the Dark by Ozzie Osbourne, and Hey Man Nice Shot by Filter. Get it?

How did we manage to get IBM to spring for a room? How did we get them to spring for food and drinks? How the heck did we get Curt Cotner to agree to a live, unrehersed podcast in front of a live audience? Well, if you've ever run into Curt at one of these conferences you'll quickly realize that he's not only one of the brightest people around, but one of the friendliest as well. Susan and I have had plenty of great hallway conversations with Curt in the past, and we finally convinced him to record one of them. Here we talk about the huge effort by IBM that is Data Studio, the one-stop development, administration, and management software hub for all things database related. We explore not only the tool, but the technologies around the tool and how they solve a lot of the most common problems facing developers and administrators today. Sue and I are having Coronas, and Curt is having a Gordon Biersch Marzen. The song beds include Sweetness by Jimmy Eat World, More Time by Needtobreathe, and Psycho by Puddle of Mudd. Special thanks to all the wonderful people who showed up for the party, and to IBM for hosting the event.

We got some special guests together, went to my room, and busted out a podcast. Our featured guest was our favorite podcast bitch Kurt Struyf with his extensive knowledge and testing of table controlled partitioning. Our other guests include Den Jenson from IBM, Gerald Pfeiffer from Trilog, and Claude Birtz from Centre Informatique de l'Etat in Luxembourg who brought us a very fine wine from his homeland. The music beds are No One's Gonna Love You by Band of Horses, Lost by Cold Play, and Trouble Maker by Weezer. Dan_Luksetich@ylassoc.com Tue, 14 Oct 2008 13:03:14 GMT http://www.db2expert.com/podcasts/db2_Cocktail_Hour_29_rrr.mp3 notes by Dan...one night in downtown Oslo, Norway we got into a fight at a bar about when and how exactly people do the three R's (RUNSTATS, REORG, REBIND). We decided to take the discussion to the airwaves! We're drinking some rose' wine of unknown origin in a small hotel in Oslo. Song beds include I Hate Myself for Loving You by Joan Jett, Fat Bottom Girls by Queen, and Pretty Flowers by Pinheads (my former punk rock project). Dan_Luksetich@ylassoc.com Wed, 04 Jun 2008 13:03:14 GMT http://www.db2expert.com/podcasts/db2_Cocktail_Hour_28_olock.mp3 notes by Dan...Locking helps assure that the database objects will be updated with consistency and integrity, and this is a very good thing. However, locking can reduce concurrency, and the higher the volume of transactions we pump through, a greater the level of concurrency is required. How can we possibly increase our concurrency by eliminating locks without losing the consistency and integrity? Enter optimistic locking. This podcast explains optimistic locking in detail, and how you can use it in DB2 for z/OS version 8 and 9. We are once again in Baltimore, and once again drinking Axios. This time, however, we're listening to Japanese noise band Melt Banana. Dan_Luksetich@ylassoc.com Fri, 16 May 2008 13:03:14 GMT http://www.db2expert.com/podcasts/db2_Cocktail_Hour_27_expl.mp3 notes by Dan...In this podcast from Baltimore we attempt to give people a good detailed strong introduction to DB2 EXPLAIN. The EXPLAIN facility allows you to externalize DB2 access path information. We cover how to do an EXPLAIN, the way to view EXPLAIN information, the critical EXPLAIN tables, and important EXPLAIN columns. We point you to where you can get all of the important information to get you going with EXPLAIN and start using it to tune your queries! We are drinking Axios wine. The music beds are Light Up by Styx, Sushi Girl by The Tubes, and 27 Jennifers by Mike Doughty. I can't stop laughing hysterically at my dramatic introduction. Light up and listen in, and also check out all the associated downloads and links below! Dan_Luksetich@ylassoc.com Wed, 13 Feb 2008 13:03:14 GMT http://www.db2expert.com/podcasts/db2_Cocktail_Hour_26_sp.mp3 notes by Dan...This podcast finds us in San Jose, California with special Guest Peggy Zagelow of IBM. We talk about some very interesting issues surrounding stored proceudres. We are drinking many bottles of wine at Peggy's house. I was drunk and did not record the podcast on the first try, and so this is actually the second attempt at recording that night. I forgot to take pictures so I scraped a picture from Peggy's MySpace page, and also took a picture of Susan and Annie bowling in Baltimore. The song beds include You've Got Another Thing Coming by Judas Priest, Bad Habit by The Offspring, and Dread and the Fugitive Mind by Megadeath. Dan_Luksetich@ylassoc.com Wed, 14 Nov 2007 13:03:14 GMT http://www.db2expert.com/podcasts/db2_Cocktail_Hour_25_ds.mp3 notes by Dan...What is DB2 data sharing, and why should we care? This podcast attempts to dive into the specifics of data sharing, but only the things that you really need to care about to get your job done, and make sure performance is optimal. Why set up a data sharing group? What are the components of data sharing? We also talk about how to share objects properly among applications and machines. We also talk about a few surprises we have come across in data sharing environments! We are in Schwaibisch Hall, Germany on the balcony of my hotel drinking a fine French Rose. Song beds include Destroy All by Static-X, One Thing by Finger Eleven, and Walken by Wilco. Dan_Luksetich@ylassoc.com Wed, 22 Aug 2007 13:03:14 GMT http://www.db2expert.com/podcasts/db2_Cocktail_Hour_24_sorts.mp3 notes by Dan...OK, sorting can be expensive, or it can be free? You see, DB2 has the ability to avoid a sort. When does it avoid a sort, and how can you take advantage of this? If DB2 does have to sort then how can you configure your DB2 subsystem resources to make that sort as cheap as possible. This podcast covers it all in very fine detail. We are again in our long time home-away-from-home, Batimore yet again! We are drinking beer and wine, again (sorry, don't remember what...again), followed by an awesome traditional dinner of steamed crab at Captain James' Landing. The music includes Jesus Built my Hotrod by Ministry, Kow Kow Calculator by Steve Miller Band, and Angels Want to Wear My Red Shoes by Elvis Costello (what diversity!!!). Dan_Luksetich@ylassoc.com Tue, 17 Jul 2007 13:03:14 GMT http://www.db2expert.com/podcasts/db2_Cocktail_Hour_23_logr.mp3 notes by Dan...Once again in Baltimore, we explore a specific application design, incorporated into DB2, called logical recovery. One of the most common data recovery problems has to do with data corruption. That is, an application or user erroneously changes data in the database, and that erroneous data needs to be backed out. Traditionally, applications are left on their own to run processes to cleanse the data, or a DBA runs a RECOVER utility to return to a prior point in time. But what about a situation in which the data has to be continuously available and the recovery requirement has to be instantaneous? Enter logical recovery! In this podcast we explore a situation in which we invented an automated process that collects changes to data in real time, and can eliminate those changes immediately while the application remains completely available! We are drinking beer and wine (sorry, don't remember what), followed by dinner at the Dog Pub (formally the Thirsty Dog). The music includes Steady as She Goes by The Raconteurs, Ain't Waisting Time No More by The Allman Brothers, and Is She REally Going Out with Him by Joe Jackson. Dan_Luksetich@ylassoc.com Wed, 16 May 2007 13:03:14 GMT http://www.db2expert.com/podcasts/db2_Cocktail_Hour_22_V9.mp3 notes by Dan...well we just had to interrupt our regularly scheduled podcast to talk about the release of version 9. We've been studying version 9 for quite some time, and there are several things we talk about in this podcast that we find exciting for application performance. So, we present our top application and SQL performance features of version 9 while guzzlying beer in Munich, Germany with our friend Chris Duellmann. We've been working quite a lot in Germany lately, and you can certainly tell by how well we drink the beer, er I mean speak the language! We are all drinking Franziskaner Weissbeer Dunkel, and yes it's real! The song beds include Party at Ground Zero by Fishbone, Upside Down by Jack Johnson, and Pretty Fly by The Offspring. Dan_Luksetich@ylassoc.com Fri, 16 Mar 2007 13:03:14 GMT http://www.db2expert.com/podcasts/db2_Cocktail_Hour_21_mrf.mp3 notes by Dan...Our first detailed podcast finds us in Schwabisch Hall, Germany. What a beautiful place!!! This behind the bar podcast is all about multi-row fetch. We talk about what it is, how to program for it, when it works, and the performance implications. We discuss programming techniques for batch and for online, and the implications of using the GET DIAGNOSTICS statement versus analyzing the SQLCA. We also talk about the strange behavior of DB2 when you mix rowset fetching with single fetching in one cursor. Check out the complimentary download below. Susan and I are drinking Haller Lowenbrau Mohrenkopfle Hefeweizen bier, which is very much my favorite beer of the area. The song beds include Don't Ask Me Why I Drink by Mojo Nixon, Red Red Wine by UB40, and One Bourbon, One Scotch, One Beer by George Thoroughgood. Prost!
