class EnsLib.EDI.X12.Adapter.TCPInboundAdapter
extends EnsLib.TCP.InboundAdapter
• property %OutLine
as %String;
Local holder for lookahead line for Parser
• property JobPerConnection
as %Boolean [ InitialExpression = 0 ];
Spawn a new Job to handle each incoming TCP connection. Allows simultaneous handling of multiple connections.
Note that the performance of this setting can be affected by changing the configured QSize setting of this adapter and by configuring Job Servers as a system configuration option.
• property QSize
as %Integer(MAXVAL=1000,MINVAL=0) [ InitialExpression = 0 ];
How many incoming connections should the OS hold open until the Business Service processes them.
The default QSize for the X12 TCP inbound adapter is 0, which supports the X12 FIFO strategy where only one connection at a time is expected and subsequent connections ought to be refused immediately.
The maximum allowed value is 1000. However, the maximum incoming connections the OS can hold open until the Business Service processes them depends on the TCP implementation.
Note: If QSize is 0 a client attempting to connect will be refused connection by the operating system (RST,ACK) if the Business Service is processing a previous incoming connection.
This could lead to a scenario where a client is connected to the Business Service but disconnects and attempts
to reconnect again in the brief period before the listening socket is re-opened by the Business Service and the client does not retry to connect as a result.
