Configure Oracle prerequisites for installing Oracle database software, fix ethernet adapter issues, set host name and IP, create Oracle user and directories, disable firewall and SELinux, and prepare startup scripts.
Understand when to cache a table from a data file in the buffer cache. Consider undo blocks and direct path read with PGA in caching decisions.
Explore the evolution of Oracle database features by version, from SQL basics to advanced tuning tools, helping DBAs diagnose performance issues and select the right parameters.
Understand how Oracle treats slight query differences, causing new SQL IDs and hash values, and how the shared pool and buffer cache influence execution and performance.
Learn how Oracle assigns query blocks to each SQL statement, generates runtime execution plans with display cursor, and uses signatures, sql IDs, and hints to map to profiles and baselines.
Discover how the SQL tuning advisor, part of the tuning pack, generates recommendations like index creation, execution plan changes, or query rewrites.
Learn to interpret Oracle 146 trace files, correlate sessions via module and action names, and analyze parsing, execution, fetch, and bind variable details for real-time SQL tuning.
