         The connection will be disconnected.

         
            
               aa....aa: 

               
                  IP address of communication target

               

            
            
               bb....bb: Port number of the communication target

               
                  0 indicates that no ports are used because
                     UNIX domain communication within the same host is specified.

               

            
            
               cc....cc: Reason connection was disrupted

               
                  
                     
                        not alive: A communication API control timeout returned from a function such as KeepAlive was detected.

                     

                     
                        no DB-CONNECT request: A timeout occurred while waiting for a DB connection request.

                     

                  

               

            
            
               S: 

               
                  Disconnects the connection.

               

            
            
               Action:

               
                  
                     
                        If cc....cc is not
                           alive

                        If this message is output by the application, reconnect.

                        If this message is output by the HADB server, no action is necessary.

                     

                     
                        If cc....cc is no DB-CONNECT request

                        A communications delay, network disruption, or an unauthorized connection from a non-HADB product might have occurred.

                        First, check the network load and whether a failure has occurred. If either of these is the cause, wait for the situation to recover.

                        If this error occurs when there is no problem with the network and there is a connection from an IP address that is not authorized to connect, consider security countermeasures such as blocking such connections with a firewall. If the connection is directly to an HADB server via the Internet, it might be an attack from a malicious third party, so such security measures are necessary. In these cases, we normally recommend that you operate so that connections to the HADB server originate only from an application server installed behind a firewall, or a similar secure setup.
