Adding Simphony to the Windows Firewall Exceptions
The Microsoft Windows Firewall that is enabled by default on your operating system could prevent the Simphony installation application from connecting to the database server. You must set up an exception rule on your firewall setting for the Simphony server and the database server to continue with the installation. For instructions setting up exception rules in Microsoft Windows Firewall, refer to the Microsoft TechNet Library at https://technet.microsoft.com/en-us/library.
Installing Simphony on Separate Servers
If you are using a separate database server, you must set up an incoming rule to allow connections from Simphony, depending on your database platform, using either the default port or the port you assign during Installation. By default, the Oracle database server uses port 1521 and Microsoft SQL Server uses port 1443. For instructions on opening a port in Microsoft Windows Firewall, refer to the Microsoft TechNet Library at https://technet.microsoft.com/en-us/library.
Starting the Oracle Listener
If you are using Oracle Linux, run the command $ lsnrctl status. If the Listener is running, you will see the listener configuration settings and the services summary.
If you are using Microsoft Windows, make sure that the Oracle TNS Listener service (for example, OracleOraDb11g_home1TNSListener) is set to Started in the Microsoft Windows Services utility.
If the Oracle Listener is not running, you need to manually restart the Listener using the Linux command = lsnrctl start. The Platform Guide for Microsoft Windows and the Administrator's Reference for Linux and UNIX-Based Operating Systems contain more information about manually starting Oracle services.
