JCO Exception 106, 102 and 104 (Very Urgent)

[venky_b]

Hi Expert,

My scenario is File to RFC i am getting the following error.

Initially i got this error

Message processing failed. Cause: com.sap.aii.af.ra.ms.api.RecoverableException: error while processing message to remote system:com.sap.aii.af.rfc.core.client.RfcClientException: resource error: could not get a client from JCO.Pool: com.sap.mw.jco.JCO$Exception: (106) JCO_ERROR_RESOURCE: Connection pool RfcClient[CC_BSV_XXXX_CTR_DIST]29fe2a7e92383d2b97a0e235d1501a19 is exhausted. The current pool size limit (max connections) is 1 connections.: com.sap.aii.af.rfc.afcommunication.RfcAFWException: error while processing message to remote system:com.sap.aii.af.rfc.core.client.RfcClientException: resource error: could not get a client from JCO.Pool: com.sap.mw.jco.JCO$Exception: (106) JCO_ERROR_RESOURCE: Connection pool RfcClient[CC_BSV_XXXX_CTR_DIST]29fe2a7e92383d2b97a0e235d1501a19 is exhausted. The current pool size limit (max connections) is 1 connections.

After resending this message using RWB i got the following error.

Message processing failed. Cause: com.sap.aii.af.ra.ms.api.RecoverableException: error while processing message to remote system:com.sap.aii.af.rfc.core.client.RfcClientException: JCO.Exception while calling ZZCRM_XXXX_IMPORT_INTFACE in remote system (RfcClient[CC_BSV_XXXX_CTR_DIST]):com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: connection closed without message (CM_NO_DATA_RECEIVED): com.sap.aii.af.rfc.afcommunication.RfcAFWException: error while processing message to remote system:com.sap.aii.af.rfc.core.client.RfcClientException: JCO.Exception while calling ZZCRM_XXXX_IMPORT_INTFACE in remote system (RfcClient[CC_BSV_XXXX_CTR_DIST]):com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: connection closed without message (CM_NO_DATA_RECEIVED)

Finally i got the following error.

Message processing failed. Cause: com.sap.aii.af.ra.ms.api.RecoverableException: error while processing message to remote system:com.sap.aii.af.rfc.core.client.RfcClientException: JCO.Exception while calling ZZCRM_XXXX_IMPORT_INTFACE in remote system (RfcClient[CC_BSV_XXXX_CTR_DIST]):com.sap.mw.jco.JCO$Exception: (104) RFC_ERROR_SYSTEM_FAILURE: Screen output without connection to user.: com.sap.aii.af.rfc.afcommunication.RfcAFWException: error while processing message to remote system:com.sap.aii.af.rfc.core.client.RfcClientException: JCO.Exception while calling ZZCRM_XXXX_IMPORT_INTFACE in remote system (RfcClient[CC_BSV_XXXX_CTR_DIST]):com.sap.mw.jco.JCO$Exception: (104) RFC_ERROR_SYSTEM_FAILURE: Screen output without connection to user.

Venki,

Open your RFC communication Channel and increase the Maximum Connection parameter to 5 or 6.

Again activate it and then try.

Venki,

I guess you are not an XI person.

You can contact any XI/PI person in your organization and tell them to do mention changes in Integraion Buider: Configuration. And then check.
