Set up the webvdme.properties file for Oracle Empirica Signal

You create and edit the webvdme.properties file to supply important properties to the Oracle Empirica Signal software.

Before you begin, if you intend to configure the Oracle Empirica Signal software to use single sign-on (SSO) with Oracle Access Manager, refer to Set up Oracle Access Manager for configuration details.

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

1. If you are installing the Oracle Empirica Signal software on this server for the first time, create a directory for temporary files created by the Oracle Empirica Signal application if it has not already been created, for example:

   $ mkdir /u01/app/oracle/product/Signal/temp

2. Set the permissions on the directory containing the log file to enable write access for the non-privileged user account.
3. Navigate to the <INSTALL_DIR>/Signal/WEB-INF/classes directory, for example:

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

4. If this is a new installation, copy the template_webvdme.properties file into the same directory, and name the copy webvdme.properties, for example:

   $ cp template_webvdme.properties webvdme.properties

5. If you are upgrading from Oracle Empirica Signal 8.x, copy your previous webvdme.properties to the <INSTALL_DIR>/Signal/WEB-INF/classes directory, for example:

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

   1. Using a text editor, open the webvdme.properties file.
   2. Edit the parameters according to the following table:

      Parameter	Description	Example
      sqlldr_connect	Specify the value <TNS_NAME>.	sqlldr_connect=orcl
      temp_dir	Specify the path to the /temp directory you created in Step 1.	temp_dir=/u01/app/oracle/product/Signal/temp
      instance.name	If you plan to use one application server to host multiple instances of Oracle Empirica Signal, provide the name of the instance. If you do not plan to use one application server to host multiple instances of Oracle Empirica Signal, leave the instance.name blank.	instance.name=dev or instance.name=
      #topicsService.url	If you plan to use the Oracle Empirica Topics feature, uncomment the line, and replace localhost with your server name and replace portNumber with the port number. If you do not plan to use the Oracle Empirica Topics feature, uncomment the line, and set the topicsService.url parameter to empty.	topicsService.url=https://myserver:7006/TopicsService/ws/topicsService The example is for an SSL environment, where you configure the SSL security policy for the Oracle Empirica Topics web service. For more information, see Set up the Oracle Empirica Topics web service security policy. For a non-SSL environment, use http and the appropriate port.
      topicsService.maxAttachmentSizeMB	Specify the maximum allowed size for Oracle Empirica Topics attachments in MB. The recommended value is 100 MB.	topicsService.maxAttachmentSizeMB=100
      #sso.plugins	To enable SSO, uncomment the line.	sso.plugins=com.oracle.hsgbu.empirica.sso.EmpiricaSsoPlugin
      #sso.EmpiricaSsoPlugin.username.header	To enable SSO, uncomment the line. The value of the sso.EmpiricaSsoPlugin.username.header property depends on your OAM configuration.	sso.EmpiricaSsoPlugin.username.header=OAM_REMOTE_USER
      #sso.EmpiricaSsoPlugin.logoutRedirectUrl	To enable SSO, uncomment the line, and replace the sample URL with your logout URL in the form <https://ssoServer:port/oamsso/logout.jsp>.	sso.EmpiricaSsoPlugin.logoutRedirectUrl=<OAM_logout_URL>?end_url=https://myserver:7004/Signal
      #help.url	To point to more current help content than what appears in the application by default, uncomment the line and replace with the url for the most recent help content.	help.url=https://docs.oracle.com/pls/topic/lookup?ctx=en/industries/health-sciences/empirica-signal/9.1/userguide&id

   3. Save and close the file.
6. For an SSO environment, update the session timeout value.
   1. Navigate to the <INSTALL_DIR>/Signal/WEB-INF directory, for example:

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

   2. Using a text editor, open the web.xml file.
   3. Edit the session-timeout parameter so that it is greater than the session timeout for the single sign-on setup in the organization.
   4. Save and close the file.
