Error in BPM: "COMMUNICATION FAILURE" during JCo call. Error opening an RFC

[Former Member]

hello experts

i am receiving the above error incase of BPM scenario where i am having a Transform step and synchronous RFC step.

i referred to the few threads discussing such problems and was trying to find whether my mapping is correct and i tested my mappings using my payload which looks good.

When looked into the Mapping trace of the BPM "Show container" i found error ""COMMUNICATION FAILURE" during JCo call. Error opening an RFC connection" and it seems that when BPM is attempting to call interface mapping it is throwing this error.

Thanks in advance.

hi,

I think no problen with the mapping part,

jco connection requird when xi try to stablish the connection with the adapter .

please look the link provided.

please also check the following parameter at the exchange profile

com.sap.aii.rwb.server.centralmonitoring.r3.ashost

com.sap.aii.rwb.server.centralmonitoring.r3.client

com.sap.aii.rwb.server.centralmonitoring.r3.sysnr

com.sap.aii.rwb.server.centralmonitoring.httpport

these parameter must be given properly.

if every thing is ok than and problem still exist than try to restart the system.

for us after restarting its worked fine.

Thanks for ur replies but my problem is it fails for specific payloads only i.e. i am able to post another payloads successfully so its not working only in certain scenarios which confuses me.

i compared the payloads and i couldn't find any difference in them but whenever i re-post the failed payload it fails again with the same exception. Initially i thought it may be the synchronous custom RFC failure but then i realized the mapping step (transformation) itself is not returning anything and in its trace i saw the above error.

Thanks and Regards

Hi,

If Error description is like this

MAPPING>JCO_COMMUNICATION_FAILURE/Error when opening an RFC connection OR

MAPPING">JCO_SYSTEM_FAILURE/

Bean SMPP_CALL_JAVA_RUNTIME3 not found

Then make sure that all your XI server nodes are up and running.

Thanks!

Solved by re-starting the XI server

Hi,

1.do a test connection of destination AI_RUNTIME_JCOSERVER

using transaction SM59 and see if it is OK...

2. delete: AI_RUNTIME_JCOSERVER

and re-create it again with the same values

3. restart the XI
