Configuring a private DNS server on Openfiler for use with Oracle RAC 12C on Virtual Boxes

This post has already been published in the past on the AMIS-blog.

To build an Oracle 12C RAC database – on Virtual Boxes – there’s at least shared storage needed for ASM, and a DNS-server for the SCAN-addresses. Several methods can be used for this, but  for the storage in my private project I chose Openfiler, an open source management storage tool, on a separate Virtual Box. It’s like a SAN in real life (the complete system will be three Virtual Boxes: two RAC-nodes and 1 storage Virtual Box). Version Openfiler: 2.99.

O.k. storage is clear, but what about DNS? The quickest and dirtiest way to accomplish this is to use Dnsmasq on every RAC-node. A nice blogpost about this subject is here to be found.

But what I want is a separate DNS-server, just as in real life. The perfect candidate is to use the separate Openfiler Virtual Box

Licensing development and test environments

This post has already been published in the past on the AMIS technology blog.

Once in a while a company wants to know if her Oracle development- and test- environments needs to be licensed. And in a lot of cases this question simply can be answered as: yes, these environments must be licensed. The cases in which these licenses are not needed, are quite rare and a company should verify this with her Oracle representative or an intermediary.

Recently I bumped into such a lucky company, and I thought it’s a good reason to write about this. And as always when talking about licenses please take notice of the disclaimer in this article.

In this post I will first shortly point out why development- and test-environments need to be licensed according to Oracle, try to explain the ‘OTN Development license’ , describe the case of the lucky company and point out some consideration to make the costs of the environments maybe more bearable.

Licensing ODA on NUP’s ?

Since Oracle launched the Oracle Database Appliance it is clear that only the Enterprise Edition is allowed on the machine. But for me it was still a little bit fuzzy if and what kind of licensing requirements is needed. More direct : may the ODA be licensed on NUP´s ? Some statements while investigating:

Documentation:

Customers are only required to license processor cores.

 

Licensing on processor cores, but not processor metric! Diving deeper….

My project with Dbvisit Standby – basics

A while ago I made a promise to take a look at the product Dbvisit, found out this is not the product, but just the firm Dbvisit. The product I’m about to install is called officially ‘Dbvisit Standby‘. There’s also a product called ‘Dbvisit replicate’.
I didn’t really know about the product, not related to it, but it was buzzing around that it’s a cheap and a well working alternative for a high available environment with Oracle Standard Edition in stead of the Enterprise Edition with Data Guard.
So my first project (this post) is just to install a lab environment and get it working. The second project should be the real thing, testing the availability and the easiness of administration and monitoring.

What will I do for this part of the project (working from scratch with the latest versions – at the time of writing – of Oracle Linux and VirtualBox…):

1. Create two VM’s (VirtualBox with Oracle Linux 6)
2. Install Dbvisit Standby
3. Configure Dbvisit Standby
4. Get it going!

And not surprisingly, the preparation took most of the time:

ODA – a brief view on a virtualized platform

Received a pdf from Oracle with the new features of the Oracle Database Appliance (when you are using the OracleVM-option).

Among other things, the two last sheets about the licensing had my attention too. I’m just showing the slides, haven’t worked with it, so I can’t tell you in detail the experiences. But the slides may give you an idea how the Virtualized Platform will look like in the new ODA, and how it will be licensed.
