Set up the listener.properties file

You create and edit the listener.properties file to store information used for data mining runs.

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. If this is a new installation or an upgrade for Signal 7.3:
    1. Copy the template_listener.properties file into the same directory, and name the copy template.properties, for example:

      $ cp template_listener.properties listener.properties

    2. Using a text editor, open the listener.properties file.
    3. Edit the parameters as needed according to the following table:

      Table describing the parameters in the listener.properties file.

      Parameter

      Description

      Example

      (Upgrade only) mgps_mem_limit

      If the value of this parameter was larger in the listener.properties file for your previous version of Empirica Signal, update the parameter with the larger value.

       

      (Upgrade only) mgps_prr_mem_limit

      For the property mgps_prr_mem_limit, Signal 7.3 had a default value of 527343. Signal 8.x requires double the amount that was needed in version 7.3, with the default being 1054686. Please review your settings.

       

      (Upgrade only) fetch_size

      If the value of this parameter was larger in the listener.properties file for your previous version of Empirica Signal, update the parameter with the larger value.

       

      mgps_path

      Specify the path to the MGPS executable. For more information, see Install MGPS.

      mgps_path=u01/app/oracle/product/Signal/bin/MGPS

      r_path

      If R version 3.3 is installed on your application server, specify the path to the directory where R is installed.

      r_path=/usr/lib64/R

      rgps_command

      If R version 3.3 is installed on your application server and you want to enable Regression-adjusted Gamma Poisson Shrinker (RGPS) computations, specify the path to the command that starts R.

      You can execute the which R command to determine the path.

      For more information, see Install the RGPS add-on package to the R library.

      rgps_command=/usr/bin/R

      rgps_cpus_count

      Maximum Number of CPU cores to use in RGPS execution.

      This value should be less than the total number of CPU cores on the machine. A larger number will speed up RGPS execution but may affect other activities on the application server.

      rgps_cpus_count=2

      sqlldr_path

      Specify the path to the SQL Loader executable.

      sqlldr_path=/u01/app/oracle/product/18.0.0/bin/sqlldr

    4. Save and close the file.

      For all other upgrades, copy your previous listener.properties to the <INSTALL_DIR>/Signal/WEB-INF/classes directory, for example:

      $ cp /u01/stage/Signal_Install_old/Signal/WEB-INF/classes/listener.properties /u01/stage/Signal_Install/Signal/WEB-INF/classes/listener.properties
