I am using WMB 7004 on Linux.
I am planning a msgflow as follow (using EG listener)
HTTPInput -- some nodes -- HTTPRequest (to vendor) ---- some nodes --HTTPReply
HTTPInput has Maximum client wait time of 5 sec
If I understand the Info center correctly, If the entire flow did not finish in 5 seconds (ie. no HTTPReply), HTTPInput will detect the timeout and if the timeout terminal is not connected, it will send a fault reply to the user.
My question is after this fault reply is sent , what will happen to the process that is still happening with the flow ? Here is what I think will happen, please help me to confirm if I am right or wrong.
1. The broker will consider the flow to be a failure and hence data base call or MQ calls (in some nodes)which has happened will be rolled back if transaction=yes is specified for the nodes.
2. If at the time, the HTTPRequest is still waiting for the response, it will be terminated without further waiting.
Is my thinking right ? and is there anything else I should consider ? |

Think it like that. If the response hits the reply node before the time out notification you're good. If not you will get an error on the good message saying something like token already used and go into error handling.

Hi fjb_saper., you said

Do you mean that the message flow will continue to execute and finally get to the HTTPReply node and got the error because the HTTP.RequestIdentifer was already used by the 5 sec timeout fault sending back to the user ?
I was actually thinking that the flow will failed once the 5 second time out fault is sent. |

Don't know at runtime, but that's the way it behaves in debug..

This was true for soap nodes in version 7 and there was a fix supplied in fix pack 6 (7.0.0.6), this may or may not apply for HTTP nodes.
