Trace Analyzer, also known as TRCANLZR or TRCA, is depracated tool provided by Oracle Server Technologies Center of Expertise - ST CoE. TRCA inputs one or several SQL trace(s) generated by Event 10046 and outputs a diagnostics report in two formats (html and text). These reports are commonly used to diagnose processes performing poorly.

The functionality provided by TRCANLZR is now included in SQLTXPLAIN as a script sqltrcanlzr.sql. A standalone installation of TRCANLZR is not supported.

TRCA identifies expensive SQL out of the provided trace(s), then it connects to the database and collects their explain plans, Cost-based Optimizer CBO statistics, metadata, configuration parameters, and similar elements that influence the performance of the process being analyzed.

For best output results TRCA must be installed and used in the same system and database where the trace is generated. Understanding that installing TRCA in a production system is not always possible, TRCA is capable of analyzing a trace using a different system.Refer to the included instructions for details.
