System TCP Keepalive Settings
You can configure the Oracle Communications Session Border Controller to control TCP connections by setting:
- The amount of time the TCP connection is idle before the Oracle Communications Session Border Controller starts sending keepalive messages to the remote peer
- The number of keepalive packets the Oracle Communications Session Border Controller sends before terminating the TCP connection
If TCP keepalive fails, then the Oracle Communications 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.
System TCP Keepalive Configuration
TCP setting are global, and then enabled or disabled on a per-interface basis.
To configure TCP keepalive parameters on your Oracle Communications Session Border Controller:
Note:
If you want to use the default values for TCP keepalive, you do not need to take Steps 1 through 4. You can simply set the TCP keepalive function in the H.323 stack configuration, and the defaults for network parameters will be applied.
