OK - fair question. I can think of two possibilities:
a) there is a known issue with the v.8.0.0.1 DFDL parser. It requests data from the TCP/IP stream after parsing has completed, leading to a timeout while it waits to be told that the stream is empty.
b) you have modified the DFDL xsds, and the model is now designed to be 'open-ended' ( it ends with an element that has maxOccurs='unbounded' ). This will, correctly, cause a timeout after every parse because the only way for the DFDL parser to know that the stream has ended is to ask it for more data.
a) is a defect, and it is fixed by IC91167 which is included in v8.0.0.2
b) is correct behaviour, caused by an open-ended model.

Hi,
I have opened a PMR for the parser issue.
Can somebody help me how to keep the same connection open for long.
The connection is being closed soon after the end of the message and opening a new connection( I have tried resering the streams and not releasing them at the end of the flow). if its opening a new connetion every time there is no point of logging-in to the connection right? |

Hi Lily,
I can help with the question about why the connections might be closing. Just to recap to make sure I fully understand what you have setup for the TCPIP nodes:
- The client node flow does not close any streams or connections. I was not sure from the other post what the options were in the client input node.
- The server node flow receives data defined by a dfdl message and does not close any connections.
It might help if you can explain exactly what you want the flow to do and possibly send me a copy of the flow to look at so i can check it does what you want. |
