Set up the log4j.properties file for Empirica Signal

You edit the log4j.properties file to specify where you want to store Empirica Signal log files.

Perform these steps using the non-privileged user account on the application server.

  1. Navigate to the <INSTALL_DIR>/Signal/WEB-INF/classes directory, for example:

    $ cd /u01/stage/Signal_Install/Signal/WEB-INF/classes

  2. Using a text editor, open the log4j.properties file.
  3. Set the log4j.appender.defaultAppender.File parameter to the file for storing Empirica Signal log messages, for example:

    log4j.appender.defaultAppender.File=/u01/app/oracle/product/Signal/logs/weberror.log

  4. (Upgrade only) If you customized the log4j.properties file for the previous release of the Empirica Signal software, apply the customizations to the log4j.properties file for the current release.
  5. Save and close the file.
  6. Set the permissions on the directory containing the log file to enable write access for the non-privileged user account.
