Trace Collier – An Oracle Utility to Mine 10046 Trace Files

   Send article as PDF   

Have you ever needed to trawl through an Oracle Trace file to extract the SQL statements executed and found a whole load of bind variables have been used, so you need to find the BINDS section, extract the values, and virtually paste them into the parsed SQL statement?

No? This utility isn’t for you then.

Update to version 0.16 and you too can compile and run this useful utility on Windows. See the Readme for details.

Trace Collier

As of 3rd March, after a Cease and Desist letter from a German lawyer,, acting on behalf of their client, Synaxus, this utility has a new name, Trace Collier. It appears that Synaxus has an unrelated software product with a very similar name to my old name, and have registered it as a trade mark. 

Their product can be found at why not take a look?

Note: Updated 2nd December 2016 for version 0.19.

Trace Collier, as it is now known, is available for download as source code, from my Git Hub repository. Click on the Download Zip button to get hold of it, then simply unzip it, cd to the created folder, edit the config.h file to suit your system, and then execute make to build the Trace Collier utility.

The README files (either markdown or HTML) have all the details.

So, given a trace file – which must have binds (10046, level 4 or 12 etc), the output will look something like this:

Trace Collier: Version 0.12
Processing: Trace file /full/path/to/nfpdpr_ora_16153.trc

EXEC Line :        Cursor ID : PARSE Line : SQL Text with binds replaced                           
     7555 :                  :            : COMMIT

     7581 :                  :            : COMMIT

     7582 :  #140136345356328:       7568 : select 00016EF5.0015.0006 from dual
     7619 :                  :            : COMMIT

So far, it has handled all the trace files I’ve thrown at it, but if yours breaks or doesn’t produce the correct results, give me a shout. My email is in the README.

There’s an option to run Trace Collier in --verbose (or just -v) mode. Don’t! You have been warned. However, if you do (and you really shouldn’t!) make sure to redirect stderr to a file which will get very very very big.
