Set up the log4j2.xml file for Oracle Empirica Topics and REST service

You edit the log4j2.xml file to specify where to store the Oracle Empirica Topics or REST service log files.

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

1. Navigate to the appropriate directory, depending on what you are using, for example:
   • For Oracle Empirica Topics, navigate to <INSTALL_DIR>/TopicsService/WEB-INF/classes directory, for example:

     $ cd /u01/stage/Signal_Install/TopicsService/WEB-INF/classes.

   • For Oracle Empirica Topics REST service, navigate to <INSTALL_DIR>/TopicsServiceR/WEB-INF/classes directory, for example: $ cd /u01/stage/Signal_Install/TopicsServiceR/WEB-INF/classes.
2. Using a text editor, open the log4j2.xml file.
3. Set the <Property name="filePath"> tag parameter to the directory where the Oracle Empirica Topics log files will be stored; for example:

   <Property name="filePath">/u01/app/oracle/product/Signal/logs</Property>

   (Upgrade only) If you customized the log4j.properties file for the previous release of the Oracle Empirica Signal software, apply the customizations to the log4j2.xml file for the current release.

4. Save and close the file.
