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
Db2 11.5 is here and with it comes a bunch of new features and changed behaviors in the area of Availability & Recovery that should make your every day tasks easier. Check out the list that includes items like Advanced Log Space Management, Reduced Logging and better HADR Reads on Standby.
With Db2 Version 11.5 the journey has begun to make log space management more autonomic. Reduce your likelihood of hitting transaction log full conditions with Advanced Log Space Management (ALSM), which is a technology preview and not supported for production environments until further notice.
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.
