Is SLOB AWR Generation Really, Really, Really Slow on Oracle Database 11.2.0.4? Yes, Unless…

Containers are huge, that’s not a secret to anyone in the IT industry, customers are testing the waters and looking for many ways to utilize containers technologies, it is also not a secret that the leading vendor in this technology is docker.

But docker itself isn’t perfect yet, while it’s as trendy as trendy can get, there are many ways around the docker runtime to provide cluster management etc’..

It all started with a customer request some weeks ago, their request was “can you show us how do you integrate with docker, Marathon (to provide containers orchestration) and ClusterHQ Flocker to provide a persistent data volume..sounds easy right? J

Wait a second, isn’t containers technologies supposed to be completely lossless, designed to fail and do not need any persistent data that will survive a failure in case a container dies??

Well, that’s exactly where customers are asking things that…
