To maintain active TCP connections

Procedure

  1. For each instance of CDC Replication, navigate to one of the following directories depending on your operating system:

    UNIX or Linux®:

    <CDC Replication installation directory>/instance/<instance_name>/conf
    Windows:
    <CDC Replication installation directory>\instance\<instance_name>\conf
  2. Open the comms.ini file in a text editor.
  3. Change the KEEP_ALIVE_TIMEOUT parameter to a value that is less than the time used to detect idle connections in your network. For example, if your network disables idle TCP connections after 15 seconds, you can change the KEEP_ALIVE_TIMEOUT parameter to a value of 10 seconds: 
    KEEP_ALIVE_TIMEOUT=10
  4. Save the comms.ini file.
  5. For the changes to take effect, use the configuration tool to restart each CDC Replication instance for which the parameter was changed.

What to do next

CDC Replication will now send messages over the TCP connection every 10 seconds.
