Error in creation of JCO with Load balancing server

[Former Member]

Hi,

We are using a ABAP user base for our WEBAS server 6.40 (with ABAP+JAVA). i have created a Public group in concerned ECC 5.0 system. I have already configured SLD, and then i maintain data supplier bridge in SLD and run RZ70 in ECC 5.0 system to load system information.. i can see details in SLD ..

now i am trying to create JCO connections .. here i am unable to create JCO with load balancing option.. i get

com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: Connect to message server host failed Connect_PM TYPE=B MSHOST=<servername> GROUP=PUBLIC R3NAME=SID MSSERV=sapms<SID> PCS=1 ERROR service 'sapms<SID>' unknown TIME Fri Jun 16 12:41:20 2006 RELEASE 640 COMPONENT NI (network interface) VERSION 37 RC -3 MODULE ninti.c LINE 505 DETAIL NiPGetServByName2: service 'sapms<SID>' not found SYSTEM CALL getservbyname_r COUNTER 1

i am able to create single server JCO, but it fails in load balancing.. is there anything i have missed out in settings...

Thanks and regards,

Sudhir

Hi Sudhir,

you must insert an entry for your R3 system

(like: sapms<SID> 3600/tcp)

in services file

(C:\WINDOWS\system32\drivers\etc\services) on Java WAS.

Hi Sudhir,

I am not sure, if you have to restart your Java WAS Server after insert an antry for R3.

I have the same problem,and solved it following the steps provided by Bogdan Rokosa :

you must insert an entry for your R3 system

(like: sapms<SID> 3600/tcp)

in services file

(C:\WINDOWS\system32\drivers\etc\services) on Java WAS.

I test the Jco successful without restart J2EE Engine.
