Trace Analyzer

Today I installed to Trace Analyzer (note 224270.1 from Metalink) to see if
this tool could make my trace files easier to read.
You can download the tool from Metalink in zip format (

Install the tool...
unzip the file

in the trca directory start a sqlplus session as sysdba...
[oracle@vamisux32 trca]$ sqlplus /nolog

TACTAB complete. Please check tactab.lis for any errors.

TACPKG complete. Please check tacpkg.lis for any errors.

Now the Trace Analyzer is installed in the EBS database.

I decided to create a trace file in EBS when querying journals in General ledger.

So, the trace file is created in the udump direcory. Lets see how it looks like

without analyzer....

You see, the trace file looks like any other trace file. Difficult to read and also not easy to understand. When using the analyzer...

When opening the html file, you see the difference....
