db2Dean’s Favorite Links

Updated 23 May 2012
There are a lot of useful tools for the DB2/LUW DBA on www.ibm.com and other web sites, but finding what you need can be frustrating and time consuming. Therefore, I have created a catalog of links that I frequently use to answer customer questions. If there are any that you like that I have not included, please send me a note at firstname.lastname@example.org and I’ll try to include it. Also please let me know if any of my links have stopped working.
Manuals and Reference Material
Down load all DB2 fix packs, clients including Admin and Runtime, and for v9 you can get JDBC, SQLJ, ODBC and CLI drivers and also Federation and DB2 Connect fixes. To use this site first pick “Information Management” in the Product Group drop down and then “DB2” from the Product drop down. The rest is pretty self explanatory. The Fix Pack Links below may stop working after July 10, 2009.
DB2 Clients and Drivers (Most Up to Date)
Down load any of the most recent DB2 clients including the Data Server Client (Includes Control Center) and the Data Server Runtime Client, plus get packages for JDBC and ODBC drivers along with Visual Studio plug-ins and driver packages for several other languages including C++.
We finally have a central location for down loading all available trial and other free software. So if you want to tryout DB2/LUW ESE, for example, this is the site for you. Unfortunately they did not put the link for DB2 Connect Developer’s Edition for Windows or DB2 Connect Developer’s Edition for Linux there, so click this link for those.
Get a free, permanent copy of DB2 for your laptop or development server. Want to try out the pureXML feature before buying? Then this is the site for you. It has lots of great information and links to down load the software.
Get a free, permanent copy of the IBM Data Studio for your workstation. This client will be replacing control center sooner or later, so you might as well get started. It works for ALL DB2 platforms including LUW, Z and I.
IBM has an in-memory database called SolidDB. Use this product when you need a relational database with the fastest possible performance. It can also persist the data in DB2 or Informix. Down your free trial by clicking the SolidDB link and click the “Try” tab.
This page contains a very easy to use chart showing which major features are included in each edition (Workgroup, ESE, etc.) of DB2
Which edition --Express, Workgroup, ESE, etc.-- is right for you? Compare and contrast them in these great articles by Paul Zikopoulos.
This link has v8 and v9 tabs that show which OS versions and minimum patch levels are required for each DB2 version. For Linux it also shows which distributions/architectures are recommended and validated for DB2.
Did you ever need to know the maximum length of a table, column or other object name? What about needing to know the size limit for a CHAR column or the biggest number that you can put in an integer field? All of these maximums and more are listed on this link for v9.7. Each version increases some limits, so please see Appendix A of the SQL Reference, Vol. 1in the manuals list in the next column of this page for your particular version.
APARS are, shall we say, the less desirable features of DB2/UDB. This page shows the critical or HIPER APARS, list of all APARS by version and the APARS fixed in each Fix Pack.
Every version of software eventually goes out of support. Review this page periodically to make sure that you don’t get a nasty little surprise in the middle of the night when you call for support for DB2/LUW.
This page contains links to many DB2 Version upgrade resources.
Browse the DB2/LUW classes by category such as “administration” or “programming”. I also find the training paths link that diagram the courses useful. Check out the Certification tab is you are interested in becoming certified in DB2.
To get support for problems and questions 24X7 you can open a PMR or ESR. Call 800-426-7378 to open a PMR, but make sure to have your CUSTOMER NUMBER handy. An ESR is a PMR opened on the web. I prefer this method because I can paste detailed error messages right into the ticket and attach supporting files. See this site to learn how to open ESRs and for a link for “ESR sign-in”.
NOTE: The following links only have older fix packs: Please use Fix Central instead!
Search for information about DB2. I frequently access the information centers to answer customer questions.
Book mark these links for the DB2 versions that you are using. I use these manual as my primary reference for answering customer questions. It is well worth reviewing the list of manuals to see what is available. You should note that the Information Centers are updated with the latest information more regularly and should be consulted if you need the most current information. If you want one book mark for all manuals, then this is the page for you.
These links show a nice summary of the new features of DB2 v9.7 and v9.5 with enough detail to make them useful. These are links to the announcement letters.
These links show which DB2 Client versions work with which each DB2 Database Server and DB2 Connect Servers.
This is a great page with links to a variety of “best practices” papers. Topics include. Physical Database Design, Database Storage, Virtualization, Performance and several others.
This is a great site for learning about how to do things in DB2 and joining discussion forums. Click the “DBAs” or “Developers” tab depending on the content that you want to see.
Search for practical guides for implementing solutions such as DB2 on Linux or implementing a Data Warehouse.
An excellent source of information about the newest features of DB2 v9. I know the author personally and I know that he really knows hit stuff.
This is the home page for all of the major DB2 Products including DB2/LUW, DB2/zOS, tools, DB2 connect, etc.

DB2 and many other software brands can be licensed by Processor Value Unit (PVU) This page shows a number of tables that show how many PVUs you have to license for each core of a particular processor type.
Most new DB2 versions and even most new DB2 fix packs contain newer versions of JDBC drivers. See this link to see which version of the JDBC driver ships with which fix pack or version.
