Mapping: JCO Communication Failure

[former_member1330829]

Hi Experts,

I am working on a scenario PROXY<-->PI<-->SOAP.

When i trigger the proxy from SPROXY, the message gets stuck in PI with an error Mapping: JCO Communication Failure. I have checked the RFC destinations AI_RUNTIME_JCOSERVER and AI_VALIDATION_JCOSERVER in the PI system, both of which are successfully connected. the correct entiry is also maintaine in sxmb_adm.

I am not sure what could be the issue otherwise. I am not sure if we are missing any configuration on the PI side.

Any idea how can i get this resolved.

Thanks in advance.

Regards

Hi Tanzoom,

You get this kind of error when there are lots of messages to be processed simultaneously.  Every message mapping needs one connection. If all 10 available connections are blocked from other messages you get this kind of error. Try increasing the the number of processes in VisualAdmin.

Hi Tanzoom,

Have you tried to take JAVA stack restart?
