- 23ai New Features and Enhancements:Explore the exciting new features and enhancements introduced in Oracle 23ai, and understand how they impact the upgrade process.

- Troubleshooting and Error Handling:Develop essential skills in identifying, analyzing, and resolving common upgrade-related errors and issues, even in a failed simulation environment.

- Best Practices and Pre-Upgrade Preparation:Learn crucial best practices for pre-upgrade preparation, including database configuration, backup strategies, and testing methodologies.

- Post-Upgrade Considerations:Understand the importance of post-upgrade tasks, such as validating database integrity, testing applications, and ensuring compatibility with existing infrastructure.

Topic 2: "Installing OEM Agent on Oracle RAC with 3 Nodes using Push Method"

Join us in this comprehensive course as we walk through the step-by-step process of installing an Oracle Enterprise Manager (OEM) agent on an existing Oracle Real Application Clusters (RAC) environment with 3 nodes using the push method.

- Prerequisites and Planning:Understand the prerequisites and planning required for installing the OEM agent on an Oracle RAC environment, including agent version compatibility, network configuration, and security considerations.

- Push Method Overview:Learn about the push method for installing OEM agents, including its benefits, limitations, and use cases.

- Step-by-Step Installation:Follow along as we perform a step-by-step installation of the OEM agent on the 3-node Oracle RAC environment using the push method, including configuring the OEM console and agent software, creating and configuring agent profiles, and verifying agent installation and configuration.

- Troubleshooting and Common Issues:Identify and troubleshoot common issues that may arise during the installation process, including agent registration, communication errors, and configuration problems.

Topic 3: "Migrating from Dnsmasq to External DNS: Valuable Lessons from a Failed Simulation"

In this insightful course, we'll attempt to migrate from Dnsmasq to an external DNS setup. Although the simulation may encounter challenges and ultimately fail, the real value lies in the wealth of conceptual knowledge and practical insights that learners will gain throughout the process.

- Understanding Dnsmasq and External DNS:Gain a thorough understanding of Dnsmasq and external DNS concepts, including their architecture, configuration, and use cases.

- Migration Challenges and Considerations:Explore the common challenges and considerations involved in migrating from Dnsmasq to an external DNS setup, including compatibility issues, configuration complexities, and potential pitfalls.

- Troubleshooting and Error Handling:Develop essential skills in identifying, analyzing, and resolving common migration-related errors and issues, even in a failed simulation environment.

- Best Practices and Pre-Migration Preparation:Learn crucial best practices for pre-migration preparation, including DNS configuration, testing methodologies, and validation techniques.

Course 4: "Add and Delete nodes in Oracle RAC"

In this hands-on course, we'll walk through the step-by-step process of adding and deleting nodes in an Oracle Real Application Clusters (RAC) environment.

- Understanding Oracle RAC Architecture:Gain a thorough understanding of the Oracle RAC architecture, including node configuration, storage options, and network requirements.

- Adding Nodes to Oracle RAC:Follow along as we perform a step-by-step addition of a new node to an existing Oracle RAC environment, including configuring the node, adding it to the cluster, and verifying node configuration.

- Deleting Nodes from Oracle RAC:Learn the process of deleting a node from an Oracle RAC environment, including removing the node from the cluster, updating configuration files, and verifying node removal.

- Troubleshooting and Common Issues:Identify and troubleshoot common issues that may arise during node addition or deletion, including configuration errors, network issues, and storage problems.

Each course is designed to provide learners with hands-on experience and practical insights into the respective topics. By the end of each course, learners will have gained a deep understanding of the concepts and techniques involved, and will be well-equipped to apply their knowledge in real-world scenarios.
