Oracle RAC migration

Oracle Database Tips by Burleson Consulting

March 23, 2015

Oracle Real Application Clusters is a high availability tool to ensure continuous availability.  Migrating to RAC is extremely complex and a RAC migration is very challenging for even a seasoned Oracle DBA. 

RAC is one of the world's most sophisticated and robust products and part of a RAC migration is choosing the right options for your database.  Hence, it is an Oracle best practice to hire consultants to migrate and configure and support your RAC database to ensure proper configuration and peak performance.

BC has Oracle certified RAC consultants and we are available to perform Oracle RAC migration for all systems, large or small.  We offer 24x7 RAC migration support and you can call out hotline for RAC migration consulting with immediate assistance.

Don't take chances with an important RAC database?  Use proven experts who can guarantee that your RAC migration is a success.

The book Oracle RAC and Grid has complete details on RAC migrations:

There are many types of migration paths. Figure 15.1 shows the two main paths.

Figure 15.1: Main procedures to migrate to Oracle Database 10g RAC

The first procedure involves the use of the existing hardware infrastructure. To use existing hardware, additional servers nodes would be added to the environment and form the cluster. Obviously the availability of Shared Storage is an important piece of the RAC architecture, since without it utilization of RAC is not possible.
