Navigating the Oracle Licensing Policy Update: A Look at the Facts

If you’re like us, then you’re never far from the pulse when it comes to changes in software licensing. Keeping up to date with this is a safe way to be sure that you’re making the best decisions for your business when it comes to saving costs and operating efficiently. 

The change that we all seem to be struggling to digest is Oracle’s January 2017 update to its online policy document, “Licensing Oracle Software (more...)

Oracle Enterprise Linux 6.6 AMI Available on AWS

We've had a number of requests for versions of our OEL AMI. The version for 6.6 has been released to the AWS Marketplace now, you can access it at this link

We're also planning to align the updates to the AMIs with our own internal updates. This will mean that the AMIs will be updated to the latest security updates for the point release on a quarterly basis. We want to make sure this (more...)

Enterprise Workloads – what can the cloud do for me?

What exactly can the Cloud do for me? 

We wouldn’t blame you if you’re bored of hearing it: if it’s in the cloud, it must be better. But…why is it better? Before you go ahead with a decision like this one, you’ll want to look at specific, concrete examples of the practical benefits of cloud-based hosting. A solution that matches the needs of one business isn’t guaranteed to be the perfect match for another. (more...)

Introducing Darwin Oracle Type Accelerator


Years ago, I created a set of XSL templates and queries to create object types out of queries on the datadictionary of the Oracle Database. It only did basic types on tables, and selects on those. I wrote an article on it that still can be downloaded here. Later, I extended the framework to also do inserts and updates and follow foreign keys. The thing with foreignkeys is that you can handle them a as (more...)

Moving your Oracle Data to the Cloud with Minimal Downtime


Moving from an on-premise Oracle database to the Cloud can mean a whole host of different challenges, and these are different for every business. One of the things we’ve tackled for larger companies is the problem of migrating a lot of data, with not much time to play with. Big businesses come with big sets of data, and often don’t have time to spare for a lengthy window of downtime. Systems down means money spent, (more...)

Business rules, common sense and query performance

Very often, significant performance benefits can be obtained by using some very basic knowledge of the application, its data and business rules. Sometimes even less than that: even if you are not familiar with the application logic at all, you can still use common sense to make some reasonable guesses that would get you a long way in improving query’s performance. Here is an example (based on an actual query that I had to tune (more...)

The Flash Insider: To POC or Not To POC?

Proof of Concept?

Guest Post

I’m excited announce another guest blog written by my good friend and funny-talking American cousin Nathan Fuzi. Like me, Nate comes from a database background but joined the all-flash storage revolution back in its infancy. Which means, like me, Nate how has a little tombstone on his résumé marked Violin Memory. But even though he has since moved up to working in THE CLOUD, Nate’s experience working for an AFA vendor is invaluable. Over six years, he worked (more...)

#Oracle cutting in inspiration and new business?

Over the many years Oracle has been leading the database world, I guess they are now taking something of a wrong turn.
Let me briefly fill you in on my thoughts.

Basically I see two “minor” shifts that are significantly indicative of this:

  1. Oracle Standard Edition 2
  2. Oracle ACE Program

Okay, so you might think I am crazy, but let me try to explain.

Oracle Standard Edition 2

Sometime last year, the long expected, (more...)

Creating a RAC cluster using Ansible (part 2)

In my previous 2 blogposts i explained how to setup a Vagrantfile that deploys 2 virtualbox machines that can be used as a basis for a RAC cluster and how you could use Ansible to deploy RAC on those VM’s. In this post i want to dive a bit deeper into how i setup Ansible and why, keep in mind that this just one way of doing this.

The Github repository containing all the files (more...)

Virtual Development Server: Provide Docker images in docker registry for Oracle XE Database and others

For later creation of containers as needed in the deployment process we have first to build docker images whenever we do not find suitable one in docker hub.

For most of my development I need a oracle database. On the internet you can find a lot of Dockerfile’s for this, but no ready image. This is because for running a database you have to accept a license and this happens when you download the installation (more...)

clckwrk Quick Guide: Run your DR solution for the cost of a backup – ERP in the AWS Cloud

In this blog we're looking at a cost effective method for disaster recovery in the AWS cloud. The key here is that the cloud gives you on-demand infrastructure so there is no need to have any servers, storage or networking kit patiently waiting for the DR button to be pushed, instead you can hold just the definition of the technology and a recent backup of your data and build the necessary infrastructure just when it is needed.

Slashing the costs of your databases … choosing your PaaS or Next Gen Database Platform

Do you want to lower the costs of your database estate? Are you trying to stay inside the license purchases you’ve made? Maybe looking to simplify the admin across servers, storage, networks and DBA?

It’s a question we get asked over and over in a world where there are great advantages in adopting the next generation of Platform as a Service (PaaS) and Next Generation database platforms. Seeing AWS park its tanks on Oracles lawn (more...)

clckwrk Quick Guide: Backing up Oracle databases on AWS using snapshots

Did you take a backup first? Of course you did.

In this post we look at one way to simply back up your Oracle database in the AWS cloud. We're planning on making this the first in a series of Quick Guides for working with Oracle and public cloud. We hope you like it, please follow, comment or like if we're hitting the spot!


This example uses a self managed database, rather than RDS, so (more...)

Protecting your data in Oracle – now you see it, now you don’t!

In this article Peter Berry from clckwrk shows how smart use of Oracle and AWS functionality can secure sensitive data in production and and automatically obfuscate when that data leaves the server.

Data security is a key concern for all businesses. Ensuring your data is secure in your production system and that data leakage is controlled is typically addressed by encryption and obfuscation respectively. Encryption can be difficult to deploy and costly while obfuscation can (more...)

New Installation Cookbook: Oracle Linux 6.7 with Oracle 11.2.0.4 RAC

cookbookI’ve updated my install cookbooks page to include a new cookbook for installation of Oracle 11.2.0.4 Real Application Clusters on Oracle Linux 6.7.

This is also the first one I’ve published since I left the employment of Violin Memory to work for Kaminario, so this install uses a Kaminario K2 All Flash Array. However, it applies very well to any Oracle RAC installation which uses relatively capable storage.

Enjoy:

When should you use Oracle RAC?

Over the past years we've worked on many Oracle projects, some with RAC, some without, some which intended to implement RAC and failed, and some which implemented poorly and ripped it out at the last minute. 

For those new to Oracle, RAC is the Real Application Cluster option for the database which lets you cluster the database servers. The main reason for using for RAC is that it brings resilience to a system, it (more...)

What DBAs need to know about Amazon RDS

We’re looking at many customers who are considering moving from on-premise  databases to cloud hosted  instances running Oracle. This is a pretty well trodden path in cloud terms and also in Oracle terms - you go through the same process with Oracle as you would have if you moved from one piece of hardware to another in the past - it’s a platform migration and sometimes you’ll upgrade the database as you go. After that (more...)

Configuring VNCR for 11.2.0.4 Oracle RAC

By default on an Oracle RAC installation, the listeners are configured to allow any database to register with them.  There is no security out of the box to determine which databases may register.  While this makes it easy to create new databases without worrying about listener registration, this can cause potential problems in a real environment.

This can be dangerous working with RAC environments where the database registers with both a local and remote listener.  The (more...)
