ODA 12.2.1.2.0: Some curious password management rules

While deploying an ODA based on the DCS stack (odacli), it is mandatory to provide a “master” password at appliance creation. The web GUI provides for that a small tooltip which describes the rules applied on password management. However it looks like there is some flexibility with those rules. Lets try to check this out with some basics tests. First… 

ODA X7-2S/M 12.2.1.2.0: update-repository fails after re-image

While playing with a brand new ODA X7-2M, I faced a strange behaviour after re-imaging the ODA with the latest version 12.2.1.2.0.

ODA – 32GB template but got a database with 16GB SGA???

I got an interesting question today from a customer which created a database on ODA. He selected the template odb-04 which shows 32GB Memory but got a database with a 16GB SGA… Is it due to the PGA size, a limitation in the system, the huge pages usage which is reached or even a bug? Indeed, the answer is easier…
