Hello,
While setting up the ABAP-read help values job, we came across this error message preventing of from proceeding:
sap.conn.jco.JCoException:
(102) JCO_ERROR_COMMUNICATION:
Connect to message server host failed
Connection parameters:
TYPE=B DEST=R3D100
MSHOST=XXXXXX22211
GROUP=PUBLIC
R3NAME=R3D
PCS=1
LOCATION
CPIC (TCP/IP) on local host XXXXXX22211 with Unicode
ERROR Group PUBLIC not found
As I wasn't able to find any discussion on this error on the forum (this might have changed now) I broadened my search to google and found the following link:
http://www.stechno.net/sap-notes.html?view=sapnote&id=1155884
Further done the page I found the answer I was looking for in:
JCoException: (102) RFC_ERROR_COMMUNICATION: Connect to message server host failed
Connection parameters: TYPE= ... GROUP=<group> ...
LOCATION CPIC (TCP/IP) on local host with Unicode
ERROR Group <group> not found ...
Use transaction SMLG in the specified communication system to determine the logon groups that exist there or to create the required logon group there
After connecting to my ABAP system I managed the logon group via transaction SMLG and the error was solved.
Just wanted to share with others who might experience a similiar error.
Cheers, Paul
Always good to share solutions to errors. What was unexpected was the in DEV systems we don't always create logon groups, but this is an easy fix now.

I am facing below issue when I am trying to connect SAP using JCO3 on Linux machine.

Hi Accenture Support Basic,
first of all I think it would make more sense to open a new question rather than recycling one that started 2013. Additionally the original question has been answered which makes it harder to find your unanswered and BTW unasked question.
This leads me to my second point: It would be helpful to ask questions rather than letting the community guess on what you want to know.
Now to your post: I assume that you want to connect to the SAP system and it does not work. What I don't know is whether it has been working before or not and whether this is a new repository and others are already working or not. You are trying to connect to an ABAP system using single host and RFC connection. The single host has IP 10.79.16.13 and you are using TCP port 3300 which is RFC protocol. So I reccommend
Regards,
Alex
Thanks for info how to solve this issue.

Thanks for updating with the solution. Yes, that's right. You would have to maintain logon groups using SMLG Tcode in the ABAP system.
Cheers,
Murali.
