1. Overview

Trace Analyzer (TRCA) is a tool that inputs an EVENT 10046 SQL Trace file, connects to the database, and outputs a comprehensive report for process performance analysis and tuning.

Free download and use

9i, 10g and 11g databases

When you generate a raw Oracle SQL Trace file you are faced with the arduous task of analyzing this trace file. 

Of course, TKPROF has always been there to help you with this analysis.

It is about another, lesser known, utility called Trace Analyzer, that is everything TKPROF is and more. 

Why is Trace Analyzer better than TKPROF?

Provides the actual values of the bind variables in SQL.

Provides the hottest blocks, optimizer statistics for indexes and tables and other information not available through TKPROF.

Separates user recursive and internal recursive calls, unlike TKPROF.

Provides more detailed wait event information.

Generates an HTML report that is more readable and extensive than the text output generated by TKPROF.

However it should be noted that unlike TKPROF, Trace Analyzer requires objects in the database and that means more configuration work on each database that needs the utility installed.

On top of this, TKPROF executes more quickly than Trace Analyzer, due to Trace Analyzer conducting more analysis than TKPROF.
