Video presentation showing us how to exploit Db2 capabilities.
Db2 recently simplified its editions structure to make the path from prototype to production deployment easier. All editions of Db2 V11.5 use the same code base, from the freely downloaded Db2 Community edition to the Db2 Standard and Advanced editions.
Here is Keri Romanufa with a presentation covering the architecture of Db2, including what is new with Db2 11.5
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.
