JCO Connection Errors

[Former Member]

Hi Experts,

we have configured the ECC6.0 backend system in to SLD and tested the same, its succesfully running and configured.

next we tried to create the Jco connection(META DATA and MODEL DATA) for the backend system, it was created with out any issues. but whenever going to Test /Ping the JCO connections we got an error.....please find the below error message.

com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: Connect to message server host failed Connect_PM TYPE=B MSHOST=iginsap1 GROUP=public2 R3NAME=EHT MSSERV=sapmsEHT PCS=1 ERROR internal error TIME Mon Jul 18 12:32:52 2011 RELEASE 700 COMPONENT MS (message handling interface, multithreaded) VERSION 4 RC -101 COUNTER 5

Note: As per some S-notes, we added the system details in to the Service file and checked the Login group also.

and aso ran below commands at the ECC server

1) niping -v -H iginsap1

2) niping -v -S sapmsEHT

3) telnet iginsap1 sapmsEHT

But still we are getting the same error... please provide the solution as soon as possible..

Arjun.

Hi,

Ensure that the backend user has SAPJSF roles assigned. Also, ensure that the password you are entering is correct.

Hi Arjunab,

Have you tried to ping the destination server from the source? Please try to mention the details like below in the source (J2EE Server) host file:

Ip Address of the backend system FQN hostname

xx.xx.xx.xxx *abcdx.xxxxatxyz.com * abcd

Hope this will help you.

HI,

I am sure this is either network issue (which can be resolved by properly administrating HOST file and Service File on windows) or access problem (which can be resolved by properly managing user id and passwor with proper authorizations)
