RFC & proxy adapters not working

[former_member440449]

Hi Gurus,

We have PI 7.31 single stack installed on our company.

Since the last 2 days, we are not able to have a successful communication between PI and ECC on RFC and proxy adapters.

On the previous days, weeks and months there were no issues like this one.

The error that we are getting on the message monitor is next one for our incoming proxy interfaces:

From the Message Details tab:

Status	systemError
Status Details	Receiver delivery: Cannot determine receiver channel (Cannot find the receiver channel)
Error Category	XI_J2EE_ADAPTER_ENGINE
Error Code	CHANNEL_DETERMINATION_FAILED

From the Message Log tab:

29/04/2015 14:56:44.448	Information	Message successfully put into the queue

For OB proxy calls, this is the error that we get in the sxi_monitor on the ERP:

Status Details column: Error Parsing PI Message

Error while calling Integration Server:

com.sap.aii.af.service.administration.api.cpa.CPAChannelStoppedException: Channel stopped by administrative task. at com.sap.aii.af.service.administration.impl.cpa.CommonCPA.checkChannelState(CommonCPA.java:57) at com.sap.aii.af.service.administration.impl.cpa.LookupManagerDelegate.getCPAObject(LookupManagerDelegate.java:86) at com.sap.aii.adapter.soap.web.MessageServlet.doPost(MessageServlet.java:487) at javax.servlet.http.HttpServlet.service(HttpServlet.java:754) at javax.servlet.http.HttpServlet.service(HttpServlet.java:847)

Regarding the RFC adapter, this is the error we can see in the CCM:

Error in processing caused by: RfcException: [qlaspi00.xxx|eq610q0]

Exception raised by qlaspi00.xxx|eq610q0

On the SM59 tx in the ERP the test connections are failing for the RFC destinations that we are using on this environment, and these were working in the past.

Also, BASIS team notify us that the programs are registered so they don't know that else to do on their side.

The actions I took were:

• CPA full refresh cache
• Restart all PI components (done by BASIS team)
• Stop and start channels
• Inactivate and Activate channels

Please notice that all these processes were working in the past and there were NO modifications on the same.

Where can I continue looking on these errors to find the issue?

Any help will be very appreciated!

Thanks in advanced!

Regards.

The error indicates that the channel has been stopped. Did you check the administrative logs in the comm channel monitor to see if someone or an ATP schedule has stopped the channel?
