Connect to message server host failed

[Former Member]

Hi,

we have created the technical system with message server port as 3600

we have used the logon Group SPACE which is existing in R/3(tcode smlg) while creating technical system.

Mantained the same port in the services file as

sapmsSRD 3600/tcp #message server port

sapgw00 3300/tcp #SAP Gateway Port

sapdp00 3200/tcp #SAP DispatcherPort

from SAP R/3 we have checked the Message server status (tcode sm51) showing no errors

and finally restarted the complete machine, inspite of all we are getting the this error :

com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: Connect to message server host failed Connect_PM TYPE=B MSHOST=192.168.220.102 GROUP=SPACE R3NAME=SRD MSSERV=sapmsSRD PCS=1 ERROR partner 'srddev1:sapmsSRD' not reached TIME Sat Jun 19 18:16:32 2010 RELEASE 701 COMPONENT NI (network interface) VERSION 38 RC -10 MODULE nixxi.cpp LINE 2835 DETAIL NiPConnect2 SYSTEM CALL connect ERRNO 111 ERRNO TEXT Connection refused COUNTER 1

Please suggest the way to take it ahead

Hi,

Thanks for the continued support.

The following are the required Details :

ABAP Stack

Instance : 00

IP : 192.168.220.102

Client : 300

SID : SRD

HOST : SRDDEV1

we have used the following telnet command

telnet 192.168.220.102 3600

Trying 192.168.220.102...

telnet: connect to address 192.168.220.102: Connection refused

telnet: Unable to connect to remote host: Connection refused

Thanks

Hi vijay,

Trying 192.168.220.102...
telnet: connect to address 192.168.220.102: Connection refused
telnet: Unable to connect to remote host: Connection refused

Firstly, can you confirm are you able to login to SRD system using SAP GUI.

If yes, then it is confirm , there is some firewall blocking between 2 system.

Then for this issue you have to get the solution from your network team.

Show them this error they will understand this easly.

If no, you are not able to login to SRD system using SAP gui.

Then you have to start SAP first.

Thanks

Hi Anil,

Thank you so much the issue is resolved...........

After restarting the ABAP stack it got resolved.

But we have encountered another issue, the following is the error message displayed :

com.sap.mw.jco.JCO$Exception: (103) RFC_ERROR_LOGON_FAILURE: Issuer of SSO ticket is not authorized

we have done all relavant settings between portal and SRM (ABAP stack).

Please suggest........

Thanks

Hi

is the issue com.sap.mw.jco.JCO$Exception: (103) RFC_ERROR_LOGON_FAILURE: Issuer of SSO ticket is not authorized is solved ? 

if not do the following

1) is the sso works between portal and srm?

2) in the backend SRM system, did you imported the ticket and added to ACL List.

3) Check the SSO ticket in the transction SSo2 and use the RFC Destination as None. there should not be any warnings or error messages.

4) regenerate the ticket in va and reimport the ticket in srm and add to acl list

Regards,

Vijay.

Hi,

com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: Connect to message server host failed Connect_PM TYPE=B MSHOST=192.168.220.102 GROUP=SPACE R3NAME=SRD MSSERV=sapmsSRD PCS=1 ERROR partner 'srddev1:sapmsSRD' not reached

error says that you are trying to make communcation between Java and abap system via JCO.

If yes, the login to the host of java system and check the entry of srddev1 exist in host file of java or not.

If no , then first make entry in host file of java i.e 192.168.220.102 srddev1 .

as well as make a entry sapmsSRD 3600/tcp #message server port in services file of java system.

After make entry restart the java application.

If entry already exist , then let us know the telnet result. i.e run the following command and share teh resut.

telnet 192.168.220.102 3600

Hi,

Anil Thanks for the clue..........

we tried to telnet from the Java stack with the following the details

telnet 192.168.220.102 3600

we are getting connection Refused inspite of firewall being disabled.

we are using RedHat Linux OS for java and ABAP stack.

Please suggest how to start the port 3600.

Thanks,

vijay.

Hi.

First check your Abap system is up or not.

If yes, it is up then check what is an instance no of abap stack.

If it is 00 then you message server port will be 3600, if it is 01 then message server port will be 3601 and so on.

First telnet on abap server it self

telnet <ip address of abap server> 36NN

( NN will be instance no )

If telnet is working then, login to the host of Java server and telnet the abap server on same port.

For e.g

From java server

telnet <abap server ip> 36NN

Let us know the result.

Thanks

Hello,

Message server port may be in use

You have to choose another, free port for message server internal

communication.
