error initializing RfcClientPool

Former Member — Mon, 09 May 2016 19:41:47 GMT

I have a PI map that has an RFC call; however, when it is called the Log Viewer often shows the following error and the message is marked as successful resulting in a false-positive failure because no target field was populated.

Error when calling an adapter by using the communication channel CC_ECC_RFC_Receiver (Party: , Service: BS_HET400_TST, Object ID: 98773518653c30a5835c7bce6314911f) XI AF API call failed.

Hello Dan,

The error details show:


ERROR       partner '*****pcs1q.hn.tds.de:[port#here]' not reached
...
ERRNO TEXT  WSAECONNREFUSED: Connection refused

There are 3 possible root causes:

The connection details (target hostname and port - SAP instance number) are incorrect;
The target system is down;
There is something in the network blocking the connection. This could be a firewall or maybe an issue at the DNS (e.g., DNS pointing the hotname seen at "partner ... no reached" to the incorrect IP address).

Regards,

Isaías

Isaias, thank you for the response. Strange thing is that I just stopped and started the comm channel used for the RFC and now it worked for 5 tests in a row. My hunch is that is was messed up after we did a cache reset and we did not stop and start all of the channels. Are you with me on this? thanks for the suggestions though.

Hello Dan,

You are welcome!

hmmm, I do no work with the PI/Java area, but I would guess that such "cache reset" should not break the RFCs...

Maybe if you send more details about this "cache reset" someone from the PI/Java area can give some inputs .

Regards,

Isaías

Hello,

We had this issue in past. When we refresh PI cache this is common issue on PI.

As far its working that is the good news.
