Check Ack Issue

[Alka Sharma]

Here is my scenario: Cloverleaf 5.8 windows platform)

My check ack proc is erroring when the message is resent. The time out to receive a reply is set to 10secs. When I do not receive the ACK, I resend the message and below is the error. I have the thread with the radio button resend OB message.

Make sure your thread has “outbound only” checked on the inbound tab. You’re getting this error because you received an ACK inbound while you were no longer waiting for one. If you check “outbound only” then these extra ACKs will be ignored.

[Alka Sharma]

I do have it checked.

[Michael Hertel]

I don’t see OBMSGID in the args, why wouldn’t that be there?

“check_ack_new {MSGID message0} {CONTEXT sms_ib_reply} {ARGS {}} {MODE run} {VERSION 3.0}”‘

[David Barr]

Is it possible that you haven’t restarted your process since you checked the “outbound only” setting?

[Michael Hertel]

The answer is that the target system received and processed all of the resent transactions in addition to the normal traffic. Therefore Cloverleaf received a bunch of ACK messages it wasn’t expecting.

Basically the ACKs got out of sync with the messages being sent.

The check_ack script processed an extra AE response.

Since there was no Outbound message, there was no OBMSGID.

Thus the script errored.

[David Barr]

I thought the “outbound only” setting was supposed to prevent this. It should do this by causing the thread to ignore any ACKs it receives while not waiting for an ACK. Please correct me if I’m wrong.

Interesting…

I understand the engine working as the 5.7 doc states below.

Your description matches the 5.8 explanation.

Alka is on 5.8 Windows.

Someone needs to test this on 5.8 to see if it really is behaving that way.

If you search the forum for OBMSGID, you will find a posting that doesn’t appear to have been resolved about disappearing OBMSGID.

It is titled: Where has OBMSGID gone?

The 5.7 doc says:

Code:

Outbound Only
Click the checkbox to make the connection send-only. The engine receives only reply messages from the host.

Clicking this button disables all other configuration entries in this pane.

The 5.8 doc says:

Outbound Only
Click the checkbox to make the connection send-only. The engine receives only reply messages from the host.  Clicking this button disables all other configuration entries in this pane.

Outbound Only checked

If the Outbound Only checkbox is checked, then Cloverleaf[code]
