Log Files 
The database system, database tools and interfaces write information and error messages in log files. Most log files are text files that you can read with a text editor.
Exceptions:
· Binary log files
· Log files that are only generated by the database system when requested by a user
To display the contents of such log files, use the Database Manager database tool, or the CCMS in SAP systems. You need the file ID of the log file.

Note that file IDs are case-sensitive.
