Question 1

How do I install and set up TPT scripts in SQL Developer?

Accepted Answer

TPT scripts are typically downloaded and run directly from SQL Developer's script runner. Ensure you have the necessary permissions and connect to your Oracle database, then execute the scripts as needed. Refer to Tanel Poder's videos for setup tips.

Question 2

TPT vs Oracle Enterprise Manager: which is better for performance tuning?

Accepted Answer

TPT offers hands-on, script-based control for deep dives and specific issues, while Oracle Enterprise Manager provides a GUI with automated monitoring and alerts. TPT is ideal for expert diagnosis, whereas OEM suits broader, enterprise-level management.

Question 3

What are the best TPT scripts for identifying slow queries?

Accepted Answer

Scripts like those for examining execution plans and wait events, such as ones analyzing V$SQL and V$SESSION_WAIT, are key. Focus on scripts that show top SQL by resource consumption or execution time for quick diagnosis.

Question 4

Can TPT be used with Oracle Autonomous Database or Cloud services?

Accepted Answer

Yes, TPT scripts should work with Oracle Cloud databases as long as you have SQL*Plus or SQL Developer access and the necessary privileges. However, some cloud-specific features might not be covered.

Question 5

How to interpret wait event outputs from TPT scripts?

Accepted Answer

TPT scripts often output wait event statistics; compare these with Oracle documentation on common waits like 'db file sequential read' or 'enqueue' to identify bottlenecks. Look for high wait times or frequent events to pinpoint issues.

Question 6

Should I use TPT or AWR reports for performance analysis?

Accepted Answer

Use TPT for real-time, interactive troubleshooting of active sessions, while AWR reports are better for historical analysis over time periods. TPT gives immediate insights, whereas AWR provides trends and baselines.
