If you ever thought you could understand what’s printed in a trace file, you might like to read this comment from a recent SR:
The trace file is reporting the steps that are needed to troubleshoot an issue. The comments tags and entries in the files may not be consistent in every scenario and their meaning can change between tasks and versions. As they are not designed or intended for direct interpretation by customers, no rationale or consistency is guaranteed.
Further, no official documentation is provided for the raw trace files. The only behaviour that is considered ‘expected’ behaviour is that which is contained in the documentation and manuals.
Of course, this does make life a little confusing – is a note that’s been published on Metalink (such as 39817.1 and 338137.1) not official after all ?
