During the month of March, we focused on Db2 LUW, where we briefly touched the new world of the Cloud: Concepts you need to know and architectures you might want to try. Be sure to check out our content :)
In this article, we will learn about how Db2 Warehouse on Cloud Flex and how its architecture can deliver high availability by leveraging several solutions, including container management.
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.
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.
When the DB2 HADR feature is enabled, the primary database's transaction logs are replicated to one or more standby databases in real time. The replication provides HA and DR protection, at a cost. The replication adds overhead to the primary's log writing.
