Timer for Idle Connections

When enabled to do so, the Oracle® Enterprise Session Border Controller monitors inbound TCP connections for inactivity. These are inbound connections that the remote peer initiated, meaning that the remote peer sent the first SYN message. You can configure a timer that sets the maximum amount of idle time for a connection before the Oracle® Enterprise Session Border Controller consider the connection inactive. Once the timer expires and the connection is deemed inactive, the Oracle® Enterprise Session Border Controller sends a TCP RST message to the remote peer.

To configure the timer for TCP idle connections:

1. In Superuser mode, type configure terminal and press Enter.

   ORACLE# configure terminal

2. Type system and press Enter.

   ORACLE(configure)# system
   ORACLE(system)#

3. Type network-parameters and press Enter.

   ORACLE(system)# network-parameters
   ORACLE(network-parameters)#

4. options—Set the options parameter by typing options, a Space, the option name atcp-idle-timer=x (where x is a value in seconds between 120 and 7200) with a plus sign in front of it. Then press Enter. This value will be used to measure the activity of TCP connections; when the inactivity on a TCP connection reaches this value in seconds, the Oracle® Enterprise Session Border Controllerdeclares it inactive and drops the session.

   ORACLE(network-parameters)# options +atcp-idle-timer=900

   If you type the option without the plus sign, you will overwrite any previously configured options. In order to append the new options to the configuration’s options list, you must prepend the new option with a plus sign as shown in the previous example.

5. Save and activate your configuration.
