About Course
The Oracle 19c RAC Training at Aalok Institute is designed for database administrators who want to gain expertise in high-availability Oracle database environments.
Oracle Real Application Clusters (RAC) allows multiple servers to run the same Oracle database simultaneously, providing scalability, reliability, and high availability for enterprise applications.
In this course, students will learn how to install Oracle Grid Infrastructure, configure RAC clusters, manage cluster resources, and administer RAC databases using Oracle utilities and command-line tools. The training also covers automatic storage management (ASM), failover mechanisms, RAC backup and recovery strategies, and performance tuning techniques.
Participants gain practical experience in cluster configuration, service management, troubleshooting RAC environments, and optimizing RAC performance using tools like AWR, ADDM, and performance views.
By the end of the course, students will be able to deploy and manage Oracle RAC systems used in enterprise data centers and high-availability production environments.
Career Opportunities After Oracle DBA Training
This course prepares learners for roles such as:
- Oracle RAC Administrator
- Senior Oracle Database Administrator
- Database Infrastructure Engineer
- High Availability Database Specialist
- Oracle Database Architect
Oracle RAC expertise is highly valued because organizations rely on clustered database environments for mission-critical applications and enterprise systems.
