Using Different Languages in Oracle – Part 2

In the previous part (you can find it here) I discussed the character sets Oracle supports and the length limits. In this part I’ll show how it is actually stored and discuss some more topics that are relevant to using different languages with Oracle. Seeing the Data In order to see how Oracle saves the data, … Continue reading Using Different Languages in Oracle – Part 2

Oracle 12.2 is Released!

Remember my post about Oracle 12.2 release date? I’ve heard rumors that Oracle changed the date to March 1st, and it was right! Oracle 12.2 is available for download for Linux x86-64, and Solaris (both SPARC and x86-64). I don’t know the release dates for other platforms. This is the download page: http://www.oracle.com/technetwork/database/enterprise-edition/downloads/index.html I’m downloading … Continue reading Oracle 12.2 is Released!

Simple Way to Export Your Data from Oracle Cloud

You should not get stuck in the Cloud. There are various options to create Oracle Cloud backup, but is very important to keep a local copy of your data. One of the simplest options to create a local copy of data from the Oracle Cloud - use Oracle SQL Developer.

Define Oracle Cloud DB connection in SQL Developer (the same as regular DB connection):


Use Database Export utility from Oracle SQL Developer:

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...)

12.2 DBaaS (Extreme Edition) possible bug/issue with the DB install/setup

A few weeks ago the 12.2 Oracle Database was released on the cloud. I immediately set an account and got my 12.2 DBaaS setup. This was a relatively painless process and quick.

For me I wanted to test out all the new Oracle Advanced Analytics new features and the new features in SQL Developer 4.2 that only become visible when you are using the 12.2 Database.

When you are go to (more...)

#DOAG2016, definitely a crazy week.

#DOAG2016, the largest Oracle Community gathering in Europe. Taking place in Nuremberg, at the Nuremberg Convention Center NCC, one of the more impressive places to hold such a conference, towering 4 stories high, with a big central atrium!!
It is a huge effort to get all of this together!

In this blog-post I want to highlight some of the crazy things I experienced this week… And… I did try to follow my own schedule (more...)

Associating Oracle Database 12c Databases with Compliance Standards

In my last post, I walked you through the first part of installing the Oracle Database 12c STIG compliance standards sample code. The next step to using these compliance standards is to associate your Oracle Database 12c databases with these standards. You may recall there are two separate standards in the sample code, one for multitenant databases and the other for conventional architecture databases. The process of associating the databases is the same in (more...)

OTN Appreciation Day: PL/SQL

We are posting these blog posts today as part of the OTN Appreciation Day, a celebration for the Oracle Technology Network as suggested by Tim Hall, inspired by Debra Lilley.

The mission was not too hard: write about your favorite bit of Oracle Technology.

As a developer and a core-tech DBA and APEX enthusiast… the choice was easy! PL/SQL (apart from how it is pronounced or even written ;-)!

Why? Easy!

Not just because (more...)

#OOW16, San Francisco, looking back

In this post I just wanted to highlight a few things that have lingered with me since the 2016 Oracle Open World Experience.

Persistent DRAM
Now, here, being at home, I must admit that I cannot find very much documentation about this, but it got me thinking… A little paradigm-shift, where computers actually wouldn’t need moving parts anymore (ie. disks of any kind). Create devices that use these memory structures, quite possibly combined with flash-disks, (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 Design Blueprint: Peoplesoft Campus Solutions on AWS

Higher eduction establishments around the world use Peoplesoft Campus Solutions from Oracle to manage their key business processes. 

In this reference architecture we look at the key requirements for Campus Solutions and the technical solutions that can be deployed on the Amazon Web Services Cloud.

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...)
