DB2 Express C 9.7 licensing changes

Licensing for DB2 Express C changed in 9.7 version a bit. DB2 Express C is still free to use and distribute, but DB2 Express C FTL - Fixed Term License is no more. FTL licensing option was moved to regular DB2 Express Edition.

This is good move because people sometimes criticised that DB2 Express FTL have more issues than regular express version. Also it will make easier sw maintenance for IBM because they can now concentrate on 3 DB2 Editions (Express, Workgroup, Enterprise). DB2…

First FixPak for DB2 9.7 LUW is here

IBM Information Management released long awaited Fixpack for DB2 9.7 also known as Cobra. This fixpack comes with

really impressive list of fixes. This list of fixes is not complete list of fixes included in fixpak. IBM, as usual, omits some included fixes from being listed. This is really annoying because our and customers DBA can not easily check (without running their testcases) if their… Continue

DB2 9.7 adoption rate

I am amazed how fast is DB2 version 9.7 moving into production. It is much faster then 9.5. I started to see first signs of 9.5 used in production for about 1 year after release.

DB2 9.7 is entirely different. Its already used, deployed on testing systems and used as standard version for new projects. Its pretty good success because there is not even single fixpak for v9.7 out. Fixpak 1 is awaited because it will add Oracle compatibility to DB2 Express Edition, which is very…

migration "to mysql" 242 000 documents found

That was pretty much expected result because mysql is highly popular… Continue
