RFC_ERROR_COMMUNICATION: Connect to message server failed

450 Views

Hi,

I think this is the most common error that one can face and have seen quite a few threads in the forum. Still, i couldn't resolve my problem.

I am getting the following error when i tried to connect to SAP using SAP JCO connector with load balancing.

(102) RFC_ERROR_COMMUNICATION: Connect to message server failed

Connect_PM MSHOST=sapserver, R3NAME=D11, GROUP=Group1

LOCATION CPIC (TCP/IP) on local host

ERROR partner not reached (host sapserver, service sapmsD11)

TIME Wed Jun 24 16:05:49 2009

I added the service sapmsD11 in the services file of my client as well as in R/3 server.

I got the above error when i tried to connect using load balancing. Without load balancing, i was able to connect to R/3 server successfully. Can any one tell how to figure out the message server host name ?

Can the application server host name and message server host name be same ?

PS: I am able to ping my R/3 server from my client.

Thanks,

Prasad.
