The log files (recording and replay) contain different information depending on the log level defined in the profile settings. Whenever you have a problem and need to contact technical support, switch the log level to Debug and try to record/replay the script again and send those files. The Debug log level contains special development information that allows Technical Support to analyze the problem quicker.
The log file contains the Oracle Forms messages that are sent between the server and the client. Additionally, in debug log-mode all client side events will be logged, for example value changed, mouse down, and more.
