Your CIO probably needs cheering up. Torn between investing in new technology and reducing spending on almost everything else, his or her job isn’t the easiest.

Changing DB2 for z/OS schema and object definitions has always been risky. Changes require outages, and it’s challenging to find time to implement them. The bigger problem, however, is ensuring the changes don’t introduce errors or performance problems. Many types of changes are risky, including application enhancements, DB2 upgrades or fixes, or schema changes. While some changes are simple and others complicated, all require careful planning, a backup plan, and a fallback plan…
