Book Review: Oracle GoldenGate 11g Implementer's Guide

I've just finished reading the book "Oracle GoldenGate 11g Implementer's Guide" written by John P. Jeffries and published by PACKT. I strongly advise this book for solution/database architects who wants to learn what GoldenGate can do and how, database administrators who are new to GoldenGate and wants to learn the technical details of implementations and GoldenGate experienced administrators who

Extreme Performance with Oracle Exadata Executive Dinner

I spoke at an Oracle marketing event in San Antonio last night. Here is a link to the promotional page for the event (it will probably disappear soon). I promised to make a copy of my slides available so here it is:

Collection of my Oracle Blog posts on Backup and Recovery

I have uploaded a collection of my Oracle Blog posts on Backup and Recovery, Control files, ArchiveLogs and such. This is now available as a PDF file. I hope that it will be useful as it is downloadable and viewable "off the web".

The entries go as far back as December 2006 and are current as of upto 03-May-2011. I have also included comments as of upto 03-May-2011.

How to Collect Statistics

May 4, 2011 In a previous article I shared a couple of the slides that I put together for an Oracle Database presentation for a specific ERP group - a presentation that as designed was far too long to fit into the permitted time slot.  I thought that in today’s blog article I would share a couple [...]

Swappiness

Swappiness, as the name suggests, affects the swapping in the Linux systems. 
Its kind of slider value. 0 means keep pages in memory as long as possible. 100 means at maximum throttle and in-between just a frequency for swapping.
The minimum value for the swappiness is 0 and the maximum is 100. The default value is 60. On the Oracle Exadata database machine it is also set to default value of 60.

Partial Page Rendering and SPEL

In this article we will discuss a specific use-case where we can use the concept of extension and personalization. Personalization is the ability to declaratively alter (in XML) the page’s UI to meet the business or user needs. Extension is the ability to programmatically (in Java) extend the page’s functionality.
We consider a page from the [...]

"The Bridge": Day 2

It is late and I am exhausted. And I have no pictures from today (/me looks at Richard Miller).

We started off on a good foot, having already taken a good stab at objectifying the tasks. We further hashed out all more objects, added more attributes, added verbs and relationships. Some objects were much easier than others; for instance, Product really only consists of a product name and version number in the scope of an SR. Yes, it is a "child" member of other objects.

16GFC Fibre Channel is 16-Fold Better Than 4GFC? Well, All Things Considered, Yes. Part I.

16GFC == 16X
If someone walked up to you on the street and said, “Hey, guess what, 16GFC is twice as fast as 8GFC! It’s even 8-fold faster than what we commonly used in 2007” you’d yawn and walk away.  In complex (e.g., database) systems there’s more to it than line rate. Much more.

EMC’s press release about 16GFC support effectively means 16-fold improvement over 2007 technology. Allow me to explain (with the tiniest amount of hand-waving).
