High availability is a critical requirement of Oracle RAC. Configuring client- and server-side connections to seamlessly handle outages helps in achieving this goal. Just as important as managing the connections to the database is ensuring that the most important business workloads get the highest priority in the database. This course covers the configuration of client and server components to ensure high availability in RAC database connections. Quality of Service Management – a component of Oracle RAC that ensures that the most critical business workloads are prioritized for database resources – is also covered. This course is one of a series in the SkillSoft learning path that cover a portion of the objectives for exam 1Z0-068 Oracle Database 12c: RAC and Grid Infrastructure.

Target Audience
Oracle Database Administrators, Systems Administrators, Technical Consultants.
