discover how to establish a performance baseline by collecting application, database, and operating system statistics, replicate issues in-house, and apply a plan-detect-resolve-implement tuning approach to optimize databases.
Learn end-to-end application tracing with dbms_monitor, enabling client id, service, and module traces, generating trace files, and using Oracle performance views to diagnose issues.
Learn how TKPROF formats Oracle trace data into readable execution plans, identifies top resource users, and guides iterative tuning with explain plan, indexes, and corrective actions.
You will get a conceptual understanding of various Oracle database performance issues and learn about different places to check for the performance information along with tuning approach.
Broadly this course will cover following:
1. What are common oracle database performance issues?
2. Where to check for messages / tuning information to get to bottom of issue.
3. Different tuning approaches - based on different databases (OLTP vs Data Warehouse).
4. Learn about database statistics, optimizer and maintenance plan for tables and indexes.
5. SQL and Instance tuning details.
6. General guidelines for avoiding performance issues in Oracle database.
