Hi Experts,

I was trying to configure the JCO destinations. After i created the JCO destinations. when i click on the test button . I am getting the following error.

com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: Connect to message server host failed Connect_PM TYPE=B MSHOST=saptcs01 GROUP=PUBLIC R3NAME=ER1 MSSERV=sapmsER1 PCS=1 ERROR partner 'saptcs01:sapmsER1' not reached TIME Tue Mar 11 17:17:03 2008 RELEASE 700 COMPONENT NI (network interface) VERSION 38 RC -10 MODULE nixxi.cpp LINE 2764 DETAIL NiPConnect2 SYSTEM CALL connect ERRNO 10061 ERRNO TEXT WSAECONNREFUSED: Connection refused COUNTER 1

I have added the entry in the service file like

sapms<SID> msgserverport/tcp

sapmsER1 3210/tcp

Added the R/3 server name in the host file

172.17.121.225 saptcs01

Can any body tell me what is the fix for this error.

Hi Vijay,

Have u made entry for ur server in hosts file??Check the file at following location

C:\WINDOWS\system32\drivers\etc . Open the hosts file in notepad & enter the details of the ur server. For example:

1. 102.54.94.97 rhino.acme.com # source server

2. 38.25.63.10 x.acme.com # x client host

If that entry is correct, check the SLD configuration.

Hi Sumit,

Thks for the reply,

I have added the R/3 server entry in the etc/host file.

<R/3 Server IP> saptcs01

then i have checked the JCO destination. It is giving the different error.

com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: Connect to message server host failed Connect_PM TYPE=B MSHOST=saptcs01 GROUP=PUBLIC R3NAME=ER1 MSSERV=sapmsER1 PCS=1 ERROR The message received isn't from a message server. Are you really connected to the message server? Please check your connection parameters.

Message Server Ports are always in the 36xx range. You put 3210, which should probably be 3610 into your services file.

Hi,

Also check these two points :

1) The user you are login in to check Jco connection.....has the backend ............

"s_rfc" profile atleast .

2) With SMLG transaction , check the logon group is PUBLIC

Ask these two to your BASIS consultant.

Thanks ,
