Documentum – Rename of Lockbox on RCS/CFS

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

As you probably know, Documentum introduced the optional use of a Lockbox since version 7. It was done initially to contribute to the security of the AEK key which is one of the central components of a Content Server. Time showed that, well, it’s not so easy and since then, nothing much changed on the Lockbox layer. With the version 16.4, OpenText introduced some new things regarding the Lockbox like the upgrade from version 3…

PDB upgrade from 12c to 18c

By | Oracle | 4 Comments

By Franck Pachot . Oracle 18c is out, in the Oracle Cloud, and the first thing I do with a new version is testing how long it takes to upgrade a previous version PDB by unplug/plug.
