WebDynpro Content admin (SP12) - JCo connection error

[Former Member]

Here is the error:

com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: Connect to message server host failed Connect_PM TYPE=B MSHOST=lal GROUP=PUBLIC R3NAME=DV2 MSSERV=sapmsDV2 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. (lal / sapmsDV2) TIME Thu Jun 30 20:10:22 2005 RELEASE 640 COMPONENT MS (message handling interface, multithreaded) VERSION 4 RC -29 MODULE msxxi_mt.c LINE 2516 COUNTER 1

We have an identical configuration in a separate SP11 instance that works fine. We have carefully compared the two instances (SLD settings in Visual Admin, Technical System Browser settings, Software Catalog settings, etc) and verified that they are the same.

Any idea what the problem is?

Thanks,

Hi Rohit,

the link you posted points to a thread that looks like the same problem, but there is no solution in that thread.

We are sure that our R/3 system is configured correctly because we can do the JCo setup in a different SP11 instance running on Windows. But in our SP12 instance on UNIX the same settings don't work.

Any other ideas?

Thanks,

Hi Jake,

You have to set the service name in the path as shown below.

c:\winnt\system32\drivers\etc\services file.

Make sure that the service name and port no are correctly copied there. It should be in the format

sapms<SID> 3600/tcp

Hope this helps you.
