TraceMiner has been updated and rewritten. Numerous bugs and foibles have been fixed.
TraceAdjust is a new, useful, utility to carry out some pre-processing on a trace file before you have to use your own weary eyes to work thorough potential Oracle performance problems! That’s why I wrote it!
TraceMiner has been totally rewritten in C++ rather than vanilla C, which has had the bonus of allowing me to fix some bugs, and do away with the need to recompile whenever you hit a system limit of some kind. You can view the readme.pdf file here.
Source code is available from GitHub as you will need to compile this utility to match your database server, or analysis systems. Tested on Windows and Linux.
TraceAdjust is a new utility which massages a tracefile to do the following:
- Add a decimal point in the tim values, to separate full seconds from micro-seconds. My eyes are too old to do it manually!
- Add a delta to the end of the trace line to show the difference between the previous tim and the current tim. This saves me doing it with a calculator, and multi-digit tim values!
- Adds a running delta since the most recent timestamp record in the trace file. Perhaps not as useful as the above, but it works for me.
- Convert the deltas so far, into actual, locally oriented timestamps showing resolution down to the micro-second.
Having the tracefile show these values already worked out does make life a bit easier when you have to get dirty in the raw traces.
