Oracle DBA 21c: Design, Manage & Secure Databases

Build practical Oracle DBA 21c skills to design, manage, monitor, and secure enterprise databases. You’ll begin with Oracle Database architecture, including servers, memory structures, background processes, and core administration using SQL*Plus and administration tools. You’ll then manage database instances, execute startup and shutdown procedures, create databases, configure password file authentication, and use the Data Dictionary and dynamic performance views to monitor activity. As you progress, you’ll administer control files, redo logs, tablespaces, datafiles, segments, blocks, and undo data to support storage integrity, recovery, and transaction management. You’ll also use Oracle SQL to create and modify tables, manage user data, compare B-tree and bitmap indexes, optimize query performance, and enforce constraints for data integrity. Finally, you’ll configure security, profiles, and resource plans while evaluating Oracle 21c features such as blockchain tables, flashback technologies, and automatic indexing. Designed for aspiring and practicing database administrators, this course combines structured modules, step-by-step demonstrations, and practical examples. Enroll to develop the applied skills needed to manage database operations, design efficient storage strategies, control access, and use Oracle 21c enhancements in enterprise environments.
