Application Gateway Unsuccessful.

[prashs]

Customer is using the Application Gateway to send the Variable to the external application and receive the updated variable through the same.

We are observing that Application gateway is unsuccessful for more than 50 % . Can we know the reson for the unsuccessful.

whether the application gateway node is not receiving the required variable or is there any timeout.

Can the router logs show me the information .

Hi,

it's either the external application sending information ICM cannot understand or the reply timed out.

You may want to try adjusting the timeout parameters for your application gateway instance in Config Manager.

Yes, the agi Router subprocess would show you what's going on.

Hi All,

I did enabled the trace and was able to see the agi process . And  I am come up with some rejections  and i see delay is more than 50 is rejected.

I am just curious to know is this because of the timeout or external host which ICM is connected that is rejecting.

[Gergely Szabo · Accepted solution]

Hi,

not because of the timeout. ICM sent Query_Req and the Application Gateway host responded correctly, with a Query_Resp message, but with the Reject flag enabled and the reject code set to 1. Remember, there are four bytes, or, an Integer for the Reject value in the Query_Resp message, if set to a nonzero value, ICM assumes the host rejected the request.

So it's time to turn to the person who controls the Application gateway, there might be several reasons:

- application gateway rejects, because... for a specific reason, for instance, insufficient resources, etc;

- the application sets this flag because of a programming error.
