How to Maintain TCP/IP Connections through a Firewall

If there is a firewall between the Web server and the Intelligence Server, the firewall may cause the TCP connection to the Web server to time out after it has been idle for a length of time. In this case, the firewall closes the connection to the Web server (outside the firewall) , but not to the Intelligence Server (inside the firewall). This results in the Intelligence Server never closing the TCP connection. Eventually, the Intelligence Server's connection limit is reached, and no more connections are allowed until the Intelligence Server is restarted.

1. Access the MicroStrategy Web Administrator page. (How?)

2. From the pane on the left, select Servers.

3. Select Modify for the Intelligence Server connection to edit. The Default Server Properties page opens.

4. Select the Keep the connection alive between the Web server and Intelligence server checkbox.

5. Click Save. The Web server will now periodically send a signal to the Intelligence Server on each open TCP connection, so that the firewall will not see the connection as idle.
