# # import_generic configuration file # # This is the companion receiver for export_generic and export_scn. It # initiates a connect request to the export specified in this file. It # will accept any legal message from the export it connected to, and put # it into the ring it's attached to. The logo of the message will the same # as it was in the originating system. # If the heartbeat string it receives doesn't match, it will quit operations. # If the expected heartbeat is not received within "SenderHeartRate" seconds, # it will re-initialize the connection. #Background: # Import/Export are the long-distance message transfer # modules. They operate as one-on-one pairs. There are two variants of # export: export_generic, which ships messages with specified logos, and # export_scn which ships only trace data, but with specified SCN names. # # Import/Export send heartbeats to each other, as well as into their # local earthworm systems. If the heartbeat from the distant partner is # not received whithin the expected time period (RcvAliveInt) the link is # terminated, and an attempt to reconnect is initiated. If things go # seriously wrong, the heartbeat into the local earthworm system in # stopped. The expectation is that "restartMe" has been set in the .desc # file, and we'll be killed and restarted. # # All socket operations are performed with a timeout. This is noramlly # defaulted, but can be set in this file (SocketTimeout). # # Export maintains a circular FIFO buffer of messages to be shipped. The # size of this buffer (RingSize) controls the maximum latency of the # data. # # #Configuration notes: # # "restartMe" should be stated in our desc file. # # The period of our local heartbeat (HeartBeatInt) must be safely smaller # (faster) than our advertised period in our .desc file (tsec:). # Otherwise we'll get continually restarted for no good reason. # Note that tsec:0 implies no heartbeats expected, and so we'll never get # restarted. # # The rate at which we send heartbeats to our distant partner should be # considerably faster than the rate at which our partner expects them. # Otherwise, a heartbeat delayed in transmission will cause our partner to # conclude that the link is broken, and cause them to break the link and # reinitialize. Which will cause us to do the same. # # For export, the ServerIPAdr is the address of the port to be used in # the exporting machine. This is to specify a network card case the # exporting machine has several network cards. # # If SocketTimeout is specified, it should be at least as large as the # expected period of heartbeats from our distant partner. # MyModuleId MOD_IMPORT_GENERIC # module id for this import, RingName PICK_RING # transport ring to use for input/output, HeartBeatInt 120 # Heartbeat interval in seconds # Should be >= SenderHeartRate LogFile 1 # If 0, don't write logfile at all, MaxMsgSize 65000 # maximum size (bytes) for input/output msgs # Note: If an oversized message is received, it will be discarded, the # socket will be closed, log an error, and it will connect and try # again.
