"Why should I use Vagrant instead of just VirtualBox?" - There are quite a lot of questions and answers of that type in the net. The questioners seem to belong to the group of operations engineers, e.g. application supporters, database administrators, etc. The answerers seem to belong to the group of developers. Hence my first clue on this queer debate is, that it may be a question of conflicting priorities in the field of the Devops movement.

Unix for the DBA: Handling Shared Memory
The Problem
There are some good introductions, but special questions are usually missing, like for instance handling the Shared Memory and the kernel parameters. A professional DBA cannot rely on system administrators, but should rather advise them in setting up Unix - Systems for Oracle databases. A crucial question is the portion of Shared Memory and how to increase it.
