Real Application Cluster (RAC) on Oracle Cloud with hands-on

Learn to set up an Oracle 12c RAC (Real Application Clusters) environment quickly and efficiently on your laptop! This comprehensive course guides you through the entire process, minimizing time and resource consumption. You'll gain hands-on experience installing and configuring Oracle 12c RAC using Openfiler as shared storage – a cost-effective alternative to expensive SAN or NAS solutions like Dell EMC or NetApp.

Course Highlights:

• Simplified RAC Setup: Get a fully functional Oracle 12c RAC environment running on your laptop.
• Openfiler for Shared Storage: Master the use of Openfiler, an OS providing both file-based and block-based network-attached storage, to emulate a SAN.
• Step-by-Step Instructions: Follow detailed, hands-on steps for each stage of the installation.
