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

Heterogeneous Batch in IBM Optim pureQuery

Optim pureQuery provides many benefits which include improved quality, improved developer productivity and dramatically improved performance over JDBC based solutions against databases which support static package binds, such as DB2.



Most often discussed about the performance benefits is static packages. However, if you have high-volume INSERT and UPDATE applications, static SQL is only a part of the benefit. pureQuery offers a Heterogeneous Batch capability which can… Continue

  2. You can now use any supported database engine (was DerbyDB only)

A Fast Way to Get Started with DB2's SQL Replication

SQL Replication is a database replication technology built into DB2 and InfoSphere Warehouse. People often ask me what's the fastest way to get started with it. I think it's best just to set up a simple configuration and go from there. That's what I'm going to show in this post. It should take about 5-10 minutes. You can then extend that…

DB2 and CouchDB sitting under a tree

Recently, I have been learning lots of interesting stuff, not directly related to db2 or database administration. I have been poking around ruby, reading about JSON, and been curious about couchdb. I wanted to test all these things out in a mini project.



Without any practical use in mind, rather than just trying stuff out, I decided to make a db2 analytics tool. Yes, yet another db2 analytics tool, because I also wanted to somehow tie ruby/json/couchdb back to my database… 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…

Big database migrations matrix

People are changing database backends for their applications for various reasons. I was interested about current trends in database migrations. I used google to search how much documents can be found to particular database migration direction.



i tried mysql first to see if google can return relevant data:

migration "from mysql" 63 700 documents found

migration "to mysql" 242 000 documents found



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