Automatically handle an IPconn reset after ipconn becomes unusable

Automatically set an autoinstalled ip connection out of service, in order to reset after conditions described in message DFHIS1015 indicating that the ipconn is unusable.

    We have assessed this requirement. We have no current plans for this to be implemented and so this requirement is being declined at this point.

    In the scenario described it is the Gateway's problem to notify CICS that it the connection is closing, so that the CICS IPIC layers can tidy up and remove the autoinstalled IPCONN. If this is not happening during a normal close of a Gateway then this a defect which the CTG team need to address. If it occurs because a gateway has failed then again we would expect CICS to be notified that the sockets that an IPCONN was using are no longer open. That should be the responsibility of the TCP/IP Stack to notify CICS about, and so the problem rests with Comms Server if this is not happening.

    When we have encountered this we set the ipconns to REL (not Out of Service) and then they reestablish themselves when a new request comes in. I am planning to do this release in an automated fashion trapping on message DFHIS1015.
