Hi All,

I am trying to implement Retry property of Result Node in Datapower.
I have set the below properties:
Backend IP:http://1.2.3.4:210/stub
Result Node Properties:
Number of Retries:5
Retry Interval: 10000

Their is no retry happening, it tries only once before completing the flow.

Below is the log entry:

Code:
mpgw (Retry_Backend_Service): Failed to establish a backside connection
 mpgw (Retry_Backend_Service): Valid backside connection could not be established: Failed to establish a backside connection, url: http://1.2.3.4:210/stub
mpgw (Retry_Backend_Service): Error occurred (port error) when connecting to URL 'http://1.2.3.4:210/stub'


Any help in this regard will be of great help.

Their is no problem with the backend connection. I was trying to implement retry scenario.
I wanted the result node to retry for more than one time in a specified interval.

The retry only applies to the Destination field, not to the Output.

For persistent connections, either side may close the connection at any time. Normally the client is responsible for determining whether it's safe to retry requests that fail due to unexpected closure of a persistent connection. However, the DataPower documentation does offer some suggestions for implementing simple retry logic within a processing policy, or for troubleshooting persistent connections.

what did you mean by -

Thank you,

The Results action has configurable fields: Input, Destination, Asynchronous, Number of Retries, Retry Interval, Method, Output, etc.

The fields for Number of Retries and Retry Interval only apply to any url(s) listed in the Destination field; they do not affect what happens to the output message after the Results action completes.

Those settings don't work unless you actually drag a new results action into your policy. Then the retry settings will actually do something.
