Oracle RAC Best Practices

Information Systems have become more demanding than ever before.  End users demand instantaneous response time, day or night, and Oracle Corporation is challenged to help provide continuous availability to their database products.  One such tool is Oracle’s Real Application Clusters (RAC). 

RAC has been used for more than a decade (via its predecessor, Oracle Parallel Server) to help provide scalability and high availability in mission-critical databases.  In a nutshell, RAC is a software tool that allows a single database to be accessed by many Oracle programs.  If one server were to fail, transactions can be redirected to a surviving server with a minimum of downtime.

As you might expect, Oracle Corporation advertizes RAC as a cure for many ailments, and shops can misunderstand the marketing hype and not recognize the costs and benefits of using RAC in a high availability (HA) environment.

Follow the link below to explore best practices with Oracle RAC and see some of the common mistakes when using this powerful cluster technology: 


Spot hidden Oracle performance trends!

Using the principles of decision support systems technology, BC has developed an important new Oracle tuning tool, Ion for Oracle. Ion quickly isolates the reports on the important optimization issues, separating the wheat from the chaff like no other performance tuning software.

After several years of hard work, Ion for Oracle is finally available for general release. Ion is unlike any other Oracle tool on the market, a tool that encapsulates expert techniques to allow a DBA to quickly visualize important trends and signatures.

Predictive analytics is the key to repairing Oracle problems before they cripple your database, and I created Ion for Oracle to allow any DBA to quickly identify changing workloads and unobtrusive patterns of data access. To try Ion for free, see here:
