Recently I attended a webinar “Oracle migration to Postgres in the Cloud”. It felt a bit like cheating, as I’m more an Oracle guy and my company is Oracle Platinum partner…. But very curious how easy it is to migrate (it depends…) and what hurdles to expect.

I attended the Enterprise Postgres Day 2019 at the nice location of Westergasfabriek, Amsterdam in the Netherlands.

Recently I got a question of a customer regarding a failover configuration. They wanted to install a second server acting as a failover server, switched off until the primary experiences an outage, and they don’t want to pay licenses for it.

Why is this a separate blogpost? It is clearly described at the github-page with Vagrant-boxes, so what can be added?

You are also able to exchange notifications between Oracle Enterprise Manager and e.g. Microsoft’s SCOM. How to monitor this heterogeneous environment. What licenses do you for monitoring? And.. […]
An updated post about NUP’s on Oracle Database Appliances. Since Oracle launched the Oracle Database Appliance HA (with two nodes) a few years ago it has become clear that from the X7-2 and further not only the Enterprise Edition is possible to use, but also the Standard Edition. But when […]
