JCO Connection Error

Hi,

We created a JCo connection for ECC server. We are getting the following exception when we try pinging or when we press Test.

com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: Connect to message server host failed Connect_PM TYPE=B MSHOST=hsdnt24s15 GROUP=PUBLIC R3NAME=C5R MSSERV=sapmsC5R PCS=1 LOCATION CPIC (TCP/IP) on local host with Unicode ERROR service 'sapmsC5R' unknown TIME Tue Feb 24 14:54:54 2009 RELEASE 711 COMPONENT NI (network interface) VERSION 39 RC -3 MODULE nixxhsl.cpp LINE 643 DETAIL NiHsLGetServNo: service name cached as unknown COUNTER 4

Regards,

Sudhir Gorantla

    Hi Sudhir,

    You have to make an entry in services file.

    Go to C:\WINDOWS\system32\drivers\etc open services with notepad

    In the last line make this entry

    sapmsC5R msgserverport/tcp (e.g. 3600/tcp)

    Save and close it.

    Now test in WD content manager.

    Regards,

    Siva

    Hello,

    Can u tell me if you have solved this issue?

    I'm getting the same error. Even after adding the sapms<SID> 3600/tcp in the host file, the error still remains the same.

    Thanks!
