Classic CDC to enable keep alive messages on the CDO connection

If there is no data changes to flow to the target , Classic CDC will leave the CDO connection idle.  Something in the network path appears to be ending these connections such that when they are used after a period of inactivity z/OS Communications Server will experience a retransmit timeout and reset the connection on z/OS.  Classic CDC will close the CDO and also the CDI connection.  As a work-around fix for this situation, we have to set up automation that issue /CHECKPOINT command in IMS to keep CDO alive.  For a long-term fix, we would like to request an enhancement to Classic CDC to enable keep alive messages on the CDO connection
