System TCP Keepalive Settings

You can configure the Oracle® Enterprise Session Border Controller to control TCP connections by setting:

• The amount of time the TCP connection is idle before the Oracle® Enterprise Session Border Controller starts sending keepalive messages to the remote peer
• The number of keepalive packets the Oracle® Enterprise Session Border Controller sends before terminating the TCP connection

If TCP keepalive fails, then the Oracle® Enterprise Session Border Controller will drop the call associated with that TCP connection.

In the ALCI, a configured set of network parameters appears as follows:

network-parameters
        tcp-keepinit-timer             75
        tcp-keepalive-count            4
        tcp-keepalive-idle-timer       400
        tcp-keepalive-interval-timer   75
        tcp-keepalive-mode             0

Then you apply these on a per-interface basis. For example, the H.323 interface (stack) configuration allows you to enable or disabled use of the network parameters settings.
