Setting 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.
- Navigate to the <INSTALL_DIR>/Signal/WEB-INF/classes directory, for example:
$ cd /u01/stage/Signal_Install/Signal/WEB-INF/classes
- Copy the template_listener.properties file into the same directory, and name the copy template.properties, for example:
$ cp template_listener.properties listener.properties
- Using a text editor, open the listener.properties file.
- Edit the parameters 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 Installing MGPS.
mgps_path=u01/app/oracle/product/Signal/bin/MGPS
r_path
If R version 3.0.1 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 3.0.1 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 Installing 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/12.1.0/bin/sqlldr
- Save and close the file.
