Just a quick FYI today to let you know about a new RedPaper offering information about exploiting client load balancing and fail over capabilities across a DB2 data sharing group (or a subset of the group members).
A RedPaper is sort of like a tip, only longer... and sort of like a RedBook, only shorter... Anyway, if you are interested in the topic, the RedPaper can be donwloaded for free by following this link:
DB2 9 for z/OS Data Sharing: Distributed Load Balancing and Fault Tolerant Configuration
News, views, and items of interest on IBM's Db2 database management system and mainframes.

A Video Interview on Long-term Retention
When I spoke at the Techxans event in Houston this past May (2008) I was interviewed beforehand on what my presentation would cover. And lo' and behold, the Techxans folks have put that interview up on YouTube, so I thought I'd share it here with my regular blog readers. Enjoy!

No Alphabetic Characters Wanted
Here is a question that was posed to me recently:
LOWER(:string) = UPPER(:string)
Of course, you will not be able to put this into a CHECK constraint because of restrictions on their content (for example, you cannot use function in a CHECK constraint). But you could use this in SQL statements and as a check in your programs before allowing data to be inserted or modified in your CHAR(10) column.
Anyone else have any other ideas?

IBM Rules the Middleware Roost
Have you seen Gartner's latest report on the middleware market?
The Gartner middleware market numbers were reported in a recent article in eWeek. Evidently, the worldwide application infrastructure and middleware software market revenue totaled $14.1 billion in 2007, a 12.9 percent increase from 2006 revenue of $12.5 billion.
Now that is quite healthy growth in what is a somewhat slow market. And right there at the top of the pile is IBM with a 28.9 percent share of what Gartner identifies as the AIM market...BEA Systems came in second with 9.3 percent of the market, followed by Oracle with 8.5 percent. However, Oracle now owns BEA and will benefit from BEA's market share (next year).
Oracle will likely continue its acquisitive ways, but IBM has not been silent on the acquisition front lately either. So I'm guessing that next year IBM will retain its #1 position with Oracle coming in solidly at #2.
For 2007, though, in terms of growth, Microsoft and Software AG posted impressive gains. Among the big enterprise software vendors, Microsoft came in at 41.6 percent revenue growth year over year. And Software AG showed strong growth with a 107 percent increase from 2006.
This is a market segment, like database software, where a small number of big players own most of the market. However, it is not quite as monopolized as the database market where three players (IBM, Oracle, and Microsoft) dwarf the rest of the field. The top five middleware vendors hold over 50 percent of the overall market and Gartner indicates that the big players are slowly eroding market share from the smaller vendors.

On The Road Again
I will been traveling extensively in June this year (2008). Last week I traveled to Phoenix to speak to the American Express Information Summit on the topic of regulatory compliance and its impact on data management and database administration. And I also spoke at the Los Angeles Area DB2 User Group on DB2 performance tuning and database trends.
This week (the second week of June) I will be traveling to Washington, DC to speak to the Baltimore-Washington DB2 User Group (BWDUG) on June 11th to deliver "The Impact of Regulatory Compliance on Database Administration." And then, later in the week, June 13th, I will be in Tampa to speak on the topic on database auditing to the Tampa Bay Relational User Group (TBRUG).
And the week after that I will be speaking to the Chicago chapter of (DAMA) on June 18th, on the topic of "Managing Data For Long Retention Periods."
So, if you are in one of the regions where I'll be speaking, I hope you can take the time to attend. And if not, you can always keep track of my speaking schedule on my web site at http://www.craigsmullins.com/speak.htm.
