My key impressions from IOD

pureQuery was one of them, mainly from the DB2 for z/OS crowd. There is definitely a trend in the market of customers wanting to take advany tage of the wealth of data stored on the DB2 for z/OS platform rather than transport that data to another platform. This trend indicates that JAVA is the preferred language when developing these new applications; however, finding an acceptable data access layer both in terms of ease of use as well as high performance, has been a challenge. Many companies are looking at things like Hibernate to address their ease of use challenges, but unfortunately Hibernate doesn't address their high performance requirement. Several customers wanted to understand how pureQuery could help them in this situation and were very excited once we talked to them about not only the benefits of Static SQL, but also the client optimization features of pureQuery, and most importantly how we could visualize the SQL that Hibernate was generating to the developer and DBA. Seems to be a perfect fit for providing the high performance that DB2 z/OS customers expect for these new JAVA applications.
The second solution that seemed to get a lot of attention was our Performance Expert solution. When it comes to problem diagnosis everyone is always looking for a better mousetrap and it seems that solutions in this area get hot and then run their course. Well, Performance Expert seems to be the up and coming hot product. I believe this is due to the sheer wealth of information this product collects. If , or should I say when, a problem occurs in production the most difficult challenge is gathering that information, especially because that moment in time is now past and you really need historical data to determine what went wrong. Performance Expert collects information and stores this information in intervals, making it incredibly easy to get the information needed all synchronized to the right time. You can see a short video of this capability here. The other thing I found interesting was all the various reports and consoles customers were writing based on the data found in the Performance Warehouse. From capacity planning to SLA reporting, it seems to me that there is a lot of customization going on that would probably make a great birds-of-a-feather session in future conferences.
As I mentioned earlier, all the solutions got their attention. I hosted a joint session with Randy Wilson from Blue Cross Blue Shield of Tennessee where Randy described a very interesting outage situation (not fun!) and how Optim High Performance Unload saved the day for them in terms of being able to supplement their recovery and provide the historical data they needed. Interesting how customers really think outside the box and come up with creative uses for our solution. After that session I had quite a few discussions with customers on how they could use High Performance Unload for situations like Randy's where back-level DB2 or dropped tables caused challenges in terms of recovery.
Well it was a busy week and now comes all the customer follow-up that happens after IOD!
