Troubleshooting and automation are tackled in the penultimate module. You’ll gain insights into common issues like connectivity and configuration problems and learn how to automate routine database functions using shell commands and cron jobs. This practical knowledge can significantly streamline a DBA’s workflow.
Finally, the “Final Assignment and Final Exam” module serves as a capstone, integrating all the concepts learned. The multi-part assignment, involving database installation, configuration, user management, backup, recovery, indexing, optimization, and automation across different databases, is a robust test of your newly acquired skills.
