1. Installation and Upgrade Instructions
  2. Set up the Oracle Empirica Signal software
  3. Set up the Oracle Empirica Signal properties files (skip for upgrades from 9.0 or later)
  4. Set up the listener.properties file

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:
    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:
      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 Oracle Empirica Signal, update the parameter with the larger value.

      -

      (Upgrade only) mgps_prr_mem_limit

      For the property mgps_prr_mem_limit, default value is 1054686. If your previous version of Oracle Empirica Signal was larger, update the parameter with the larger value.

      -

      (Upgrade only) fetch_size

      If the value of this parameter was larger in the listener.properties file for your previous version of Oracle 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 4.0.5 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 4.0.5 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 or upgrade 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/19.3.0/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
