Information architecture essentials, Part 7: Data-store designValuable business information should never be left sitting around. It should be organized and saved into a permanent data store. A legacy database tends to become the final resting place for useful business information -- and this information is essentially lost, because it can't be accessed in a meaningful way. Data-store design can help you establish an efficient mechanism to store and retrieve valuable business information. |

DB2 Code Pages: Don't Get Lost in TranslationFor a long time, many of us in the DB2 community didn't pay a whole lot of attention to code pages (referring to the standard representations of numbers and letters and other characters within computer systems). There didn't seem to be much of a reason to think about this particular topic. Data went into the database and came out of the database just fine, so what was the big deal about coded character set translation? Oh, sure, everyone knew that an ASCII-based… |

Deleting SAP idocs with Transaction we11I'm not talking about deleting as the last step of idoc archiving, I'm talking about simple straight forward deletion of idocs from the database. I don't know how this transaction managed to elude me for 3 years, but it did, so there is a good chance I'm the only one who has never heard of it... |

Ruby on the rise ?Ruby is on the rise in programming circles according to Darryl Taft.
What is the take away? If Ruby is the fastest growing programming language it is definitely worth adding to your developer's toolbox. If the estimates are correct then growth from 1 million to 4 million developers is very significant. An updated JVM and enhancements to JRuby will definitely spur new deployments across the board. As you are discovering Ruby, you should consider throwing IDS 11 Developer Edition or DB2 Express-C 9.5 into the toolbox along side the Rails and Ruby handbooks. |

Do you Twitter?If you answered "Yes", you already know what I'm going to blog about today and hopefully you're also already following me on Twitter. However, if you are part of the vast majority that don't know about Twitter (or maybe would rather not know about Twitter, or maybe have just had it with people trying to get you into social computing), you may want to read on. Twitter is one of the many sites where you can micro-blog. Micro-blogging i |

APAR Friday: Five for FridayI'm back with my Friday APAR hunt. This week I thought I would concentrate a few HIPERs.

The information perspective of SOA design, Part 7: The execution approach for the data quality analysis pattern in SOAThis is the seventh paper in a series called the “The Information Aspect of SOA Design." The purpose of this article is to demonstrate to an architect community the execution approach of detailed data quality analysis in the context of an SOA environment. This article focuses on the implementation of data quality analysis regardless of the specific technology in use, and will be followed by a related article that describes in more detail how the related IBM products (WebSphere Information Analyzer) can be used in this context. |

Index CompressionI guess it 's time to get back to blogging about how stuff works. I have a little more time to think right now; in between articles and have no presentations due to any conferences in the near future, so I will use the few minutes of extra time for some good old fashion tech blogging. Although DB2 adds index compression in DB2 9, the term compression is where similarities to data compression quickly end: |

DB2 for Linux, UNIX, and Windows Versions 8, 9.1 and 9.5 Security Vulnerabilities and HIPER APARsDid you catch the 21 April 2008 IBM Flash Alert? Since not everyone subscribes to IBM alerts, I thought it prudent to bring your attention to new fixpacks here. It seems IBM acted reasonably swiftly and appropriately to create these new fixpacks for V8, V9, and V9.5, which address the documented vulnerabilities. |

Finding the Right Page Size for Your Indexes on InformixIn my last blog we took a look at storing indexes in a dbspace with a large page size to try to decrease the number of levels in an index and increase performance by reducing the number of I/Os required to traverse the index. Using the largest page size available, 16K, we were able to decrease the number of levels in our test index from 5 to 4, but only realized a slight performance gain if--and only if--we increased our resident segment (buffers) from 512 MB to 1.5 GB to compensate for the larger, less selective page size and larger cache miss penalty of a 16K disk read vs a 2K disk read. I ended the blog with the suggestion that the best solution would be to find the smallest page size that still reduces the number of levels, giving us the benefits of better caching through smaller index pages and the benefits of reduced index levels when using larger page sizes. |

DB2 for z/OS Accounting: And a One, And a Two...When people analyze DB2 for z/OS monitor accounting reports or online DB2 monitor displays of thread detail data, they often pay particular attention (with good reason) to the elapsed and CPU time figures contained therein. Some of these same folks are a little confused as to the meaning of the numbers they are examining. They see columns of figures under headings that read (depending on the monitor product) "Class 1" and "Class 2" or "In-Application" and "In… |
