Every organization is looking for Database High Availability (HA), scalability, Performance and security for all the real time environments mostly banking and financial sectors (OLTP). In this case Oracle® has been introduced the Real application clustering (RAC) in means that the transactional data will be available for any time and there is no users and customers will not impact on any circumstances. If this data is not available in production then organization to lose the business as well as negative publicity in the world. To build a highly data available (HA) infrastructure is critical to the success of all organization and will increase the Organization business growth also.

This Oracle Database 11g: RAC Administration Release 2 NEW training explores RAC database administration in the Oracle Grid Infrastructure environment. Expert instructors will help you develop the skills to administer cluster databases using Enterprise Manager and command-line utilities like SRVCTL, CRSCTL and SQL*Plus.
