If you are interested in trying this then a colleague of mine, Phil Newlan has written a white paper with associated scripts which provide some common sample implementation scenarios. The paper is called 'Using Oracle Clusterware to Protect
a Single Instance Oracle Database' and is available from the RAC landing pad on
OTN http://otn.oracle.com/rac. The
scripts used in the paper together with a copy of the paper are also available
on the "RAC Sample Code" page. The scripts can be used to protect a single
instance database and, if required an ASM instance
and listener.
Oracle Clusterware is usually associated with RAC, however it can be used to protect a single instance Oracle Database. Using the technology in this way
cold failover for single instance Oracle Databases can be implemented on a purely Oracle stack.
Please note that that these are provided as a 'free' example of what can be achieved with Oracle Clusterware, please read the papers and adjust the scripts according to your own environments needs.
If you do get chance to try this please feel free to feedback either via this blog or via email to philip.newlan@oracle.com

Enterprise portals are specifically designed to be the
single source of interaction with corporate information and the focal point for
conducting day-to-day business. The Oracle Application Server includes a
complete and integrated solution for building, deploying, and maintaining a
world-class enterprise portal. To illustrate this we have references for many thousands of internal users and Oracle Portal can also be deployed over the Internet.
Oracle Portal combines a
rich, declarative environment for creating a portal Web interface, publishing
and managing information, accessing dynamic data, and customizing the portal
experience with an extensible framework for any Web-based technology, such as
J2EE-based application access and Web Services. Using Oracle Portal,
e-businesses have the power to connect employees, partners, and customers with
the information they need, as well as the flexibility to create views tailored
to each community.
Information on Oracle Portal
A full list of customer success stories is here.
One of the key benefits of using Oracle portal is that you can get a consistent look to your applications. This will then allow the new integration architectures to be implemented in the background with minimal impact on how your users access the data and functionality in your organization.

It's a perfect name isn't it? The first time I saw the name it felt like I was going to get something that would allow me to "sleep" the database until I wanted it to wake up again. I could then turn this off in a benchmark and be a performance guru!
At least I got the performance bit right. Did you know that "Oracle professionals have been slowly migrating
away from performance analysis techniques that focused on blanket
system ratios to a methodology that instead zeros in on where a system,
application, or session is spending its time. Referred to as wait-based
analysis or bottleneck analysis, its goal is to uncover the true nature
of performance degradation by determining the exact causes of
throughput hindrances." This is the Oracle Wait Interface
This has been brought to my attention by a customer who has recently purchased a book on this subject.
As always a different view on performance can sometimes help break a problem and I have it on good authority that this has been used in a number of accounts by Oracle and non-Oracle experts alike, so I hope that this will prove to be another technique to add to the performance kitbag.

For those of you have been following my blog (and career) with interest, I have some news. After a number of years working in the technology arena, I am returning to more of a business focus and am moving into the UK Customer Relationship Management team. For more information on CRM try here:

As I embark on this path, I will endeavour to update you with how my own education is going and hopefully in turn will help to educate those around me.
