Knowledge increases exponentially. Today, you probably own more books than great universities of times past—Cambridge University owned less than two hundred books in the fifteenth century. First came the invention of writing, then alphabets, then paper, then the printing press, then mechanization. Each step caused an exponential increase in the collective human knowledge. In our generation, Al Gore invented the internet and the last barriers to the spread of knowledge have been broken. Today, everybody has the ability to contribute, communicate, and collaborate. We are all caught up in a tsunami, an avalanche, a conflagration, a veritable explosion of knowledge for the betterment of humankind. This is the blog of the good folks at Database Specialists, a brave band of Oracle database administrators from the great state of California. We bid you greeting, traveler. We hope you find something of value on these pages and we wish you good fortune in your journey.

As Oracle consultants we often get caught up in the esoteric areas of performance, such as contention, complex execution plans, and obscure parameters.  But we forget that sometimes it’s the little things that count, many of which we learned in the DBA101 phase of our careers.
I was reminded of this recently at one of our [...]

The importance of testing recovery

As a database administer, it’s very important not to forget one of our main responsibilities; that being insuring that the database(s) we’re responsible for, can be recovered in the case of an emergency.  Read my short presentation here, for thoughts on this important topic.

To upgrade or not to upgrade, that is the question

We are frequently asked by clients whether they should upgrade to Oracle 11g. Oracle Corporation’s communications understandably promote using the latest version, and tout its new features. The answer to the question isn’t a simple one, and (like so much else in our world), “it depends”.
One of the traditional answers given by people in the [...]

Standard Practices

 
Most Oracle professionals who focus on performance optimization are familiar with Method-R, which Cary Millsap tirelessly promotes.  Briefly stated, this method focuses on a specific process which is not performing satisfactorily.  We trace the process and see precisely what the process is doing.
 
We recently had a problem in which client connections were failing about half [...]
