Automated application testing for web services with a Db2 repository is not an easy task, and it invites for creative solution. On this post, David Morris shows how this can be accomplished with the aid of tools like Jenkins and H2 as a means of providing a test scenario that mirrors a Db2 database.
Thinking about your availability and recovery strategy shouldn't give you sleepless nights. Db2 understands the importance of keeping your database online 24x7 and with Db2 11.1 / 11.5 and its continuous delivery of new features and enhancements, you are on the right path of achieving such goals.
Moving to a new version or fix pack of DB2 should not be a scary event for databases using the high availability disaster recovery (HADR) feature. Fear of an outage or re initialization of your standby is no longer a concern.
If you are a serious Db2 user, chances are you have downloaded and used free Db2 versions for a few years. Db2 Express-C was a free way to learn Db2 on Linux, Unix and Windows, to practise and test your SQL skills and in later versions implement or ship Db2 with your small production application.
Availability of data is a must these days. Everything has to be up and running, data outages are becoming few and far between and preferable non-existing. With every release Db2 for z/OS becomes more highly available; however this requires the usage of new features and structures.
