Optimising AWS for Oracle – Licenses


If you're keeping an eye on the Oracle license rules you'll know that you need to make sure that when you're designing in AWS you make the most of every CPU that has an Oracle license attached too it.

Here's our rundown of how to design and use AWS features to maximise those licenses.

  • Design for zero waste. In the past we might have Oracle nodes that didn't do very much. Those DR servers, or (more...)

NFRs are easy – what about your NFO’s?

You're used to working on your Non-Functional Requirements (NFR's) - we're used to worrying about how secure our systems are, how many users they will support, how resilient they are to the failure of a component. What we're not used to thinking about are Non-Functional Opportunities - (NFO's) what are the unforeseen benefits that the business will find when they use IT?

The cloud blows the non-functional requirement (NFR) out of the water. You want (more...)

G-Cloud – Moving Your Oracle System to Amazon Web Services

G-Cloud was awarded a few weeks ago and we're glad to say that clckwrk were selected as a supplier in the areas of Infrastructure as a Service and Specialist Services.

The services we have on G-Cloud are specifically curated for implementing, moving and managing Oracle systems to the cloud. This is a quick guide for how to combine those services to migrate to the cloud. For public sector users of Oracle technology and applications this is the set (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. 




Availability: Campus solutions needs a high availability infrastructure to ensure that both the administrative and student users can access data at all times. This solution uses multiple web and (more...)

Its what we do at clckwrk…

At clckwrk we have a pretty simple way of looking at what we do:
  • Discovery: Finding out about your IT and your plans for the cloud; what you have, what works, what doesn't, where you want to get too
  • Design: Working on the way things should be; what things will look like in the end, what steps will get us there, making sure everything continues to work along the way
  • Build: Getting it (more...)

Oracle Licensing Costs on AWS, Self Managed vs RDS

When you move your Oracle database to AWS there are a number of ways to handle licensing. You can either:

  1. Bring your own licenses for a self managed Oracle installation on an EC2 instance 
  2. Bring your own licenses for an Oracle Relational Databases Service instance
  3. Use pay as you go licensing for an Oracle Relational Database Service instance
Of course you need to be sure that you’re getting best value from your licenses - in (more...)

clckwrk Quick Guide: Oracle DBA – Managing the Alert Log on AWS

At clckwrk we managed Oracle on the AWS Cloud. First rule of being a DBA - check the alert log.

The database alert log is the file where the database logs core activity and any messages that the DBA needs to understand what the database is doing, any tuning that needs to happen at the database level and any errors that the database is producing. It's the errors that are critical for us as they (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...)

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...)

Getting connected to the AWS Cloud

One thing that comes up in every clckwrk engagement is the issue of getting connected to the cloud. It’s a common issue so worth lining up the options and seeing which is going to work for you. We’ve listed below the 3 most common  paths for connecting your office or data centre to the AWS cloud and the pro’s and con’s of each. 

Internet - the simplest and by far the most common way (more...)
