Oracle RAC Online Training

ORACLE RAC ONLINE TRAINING @ VIVANTA IT LABS


Oracle RAC Online Training:
An Online Course designed to make you an expert in RAC database administration in the Oracle Grid Infrastructure environment to administer cluster databases using Enterprise Manager and command-line utilities like SRVCTL, CRSCTL and SQL*Plus.
Oracle RAC Online Training Overview:
A cluster comprises multiple interconnected computers or servers that appear as if they are one server to end users and applications. Oracle RAC enables you to cluster Oracle databases. Oracle RAC uses Oracle Clusterware for the infrastructure to bind multiple servers so they operate as a single system. Oracle Real Application Clusters (Oracle RAC) is a clustered version of Oracle Database based on a comprehensive high-availability stack that can be used as the foundation of a database cloud system as well as a shared infrastructure, ensuring high availability, scalability, and agility for any application.
Oracle RAC is a key component of Oracle’s private cloud architecture. Oracle RAC support is included in the Oracle Database Standard Edition for higher levels of system uptime. Oracle’s premier shared disk database clustering technology, Efficiently runs any packaged or custom application and Choice of administrator-managed or policy-managed deployments.
