Organization of this subsection

(1) Server property file

(a) eads.logger.dir

This parameter specifies the path of the output destination directory for log files output by the EADS server.

If the specified path does not exist, it is created.

For details about the log files output under the directory specified in this parameter, see 7.4.2 Specifying the file output destinations.

The path of an output destination directory can consist of a maximum of 96 characters, including alphanumeric characters (0 to 9, A to Z, a to z), underscores (_), colons (:), and separators (forward slashes (/)).

If you have changed the value of this parameter, either move all files and directories specified in this parameter to another directory or delete them.
