RFC_ERROR_LOGON_FAILURE

[#1]

Hi Experts,

I have a BPM scenario IDoc(ORDCHG.ORDERS05) to cXML, the message caught the below error

com.sap.aii.af.ra.ms.api.DeliveryException: error while processing message to remote 
system:com.sap.aii.af.rfc.core.client.RfcClientException: could not get a client from JCO.Pool: 
com.sap.mw.jco.JCO$Exception: (103) RFC_ERROR_LOGON_FAILURE: Name or password is incorrect. Please re-enter

the scenario was running OK before and also the RFC receiver comm channel is having green status now.

Please suggest how to resolve and resend the message.

Thanks,

Hi Mk,

Basically this is a connectivity issue as Java and ABAP stacks communicate with JRFC & For this several gatway connections (JCO)must be defined.

During communication if connection is already occupied then it gives this error.

In your case max size is 1.and while communication that connection had occupied by another resource thats why you are getting this error

Solution: ask your admin (basis ) guy to make this max no of connection 300 which is a no recommended by sap itself.

And also J2EE application which uses either Java Remote Function Call (JRFC) or Java Resource Adapter (JRA) to connect to an SAP system has caught JCo exception com.sap.mw.jco.JCO$Exception

JCO_ERROR_RESOURCE

Indicates that JCO has run out of resources such as connections in a connection pool

Action & Read the exception text and check the JAVA application.
