The following notes apply to all logs and traces other than the performance analysis traces:

• Files cannot be edited.
• A text viewer or editor with a lock option is not supported. If files are locked, no trace can be output.
• File access permissions cannot be changed.
  If you need to set access permissions manually, set appropriate access permissions. If the access permissions you set are not appropriate, trace output is disabled.
  
• The file update time cannot be changed.
  If you change the file update time, the output target file may be altered.
  
• Do not rename or delete a file during trace output processing.
  The target file can be determined from information in the management file. If the management file is not available or is damaged, the output target file is determined based on the file update time. If you need to rename or delete a file, first terminate all trace output processes.
  

• The linefeed code at the end of a message is always CR+LF regardless of the platform you are using.
• The following notes also apply to exception and maintenance logs:
  
  • To enable the function for changing a file size, the number of files, or the mode option, you may need to delete files. Before you delete a file, terminate the trace output process.
  • In an output trace file, data up to the first EOF character (0x1A) is valid. Data following the EOF character is not guaranteed. Note that the first EOF character may be followed by another EOF character.
  • Even when a trace is output, updating of the file update time is not guaranteed. Whether or not the trace has been output cannot be determined based on the file update time. The file update time is updated when trace output processing is terminated.
