WebLogic – SSO/Atn/Atz – How to enable debug logs

By | Application integration & Middleware, Entreprise content management | No Comments

Let’s say that you have an application deployed on a WebLogic Server and that the SSO/Atn/Atz (SSO/Authentication/Authorization) isn’t working or throwing a 4xx error code like ‘401 – Unauthorized’ or ‘403 – Forbidden’. How would you be able to know what is happening and how to solve it? Well the answer is always the same: enable debug logs, it is just a matter or choosing the right scope and choosing a way to do it…

firewalld rules for Veritas Infoscale 7.3 with Oracle

By | Database Administration & Monitoring | No Comments

You might wonder, but yes, Veritas is still alive and there are customers that use it and are very happy with it. Recently we upgraded a large cluster from Veritas 5/RHEL5 to Veritas InfoScale 7.3/RHEL7 and I must say that the migration was straight forward and very smooth (when I have time I’ll write another post specific to the migration). At a point in time during this project the requirement to enable the firewall on…

The new release of Oracle VM VirtualBox (aka VirtualBox) is there with a new functionality to export a VM to the Oracle Cloud Compute (aka Oracle Cloud Infrastructure). That can be interesting to prepare a VM on my laptop and move it to the Cloud to get it accessible from everywhere. Here’s my first try.
