Connect to message server host failed;WSAECONNREFUSED: Connection refused

Hi All,
I am getting the following error when I tried to test the system connectivity from the portal to NSP instance.
Connection failed. Make sure that Single Sign-On is configured correctly
I found the following entry in the logs

I checked the services file and have the sapmsNSP entry.
I am able to launch an SAP transaction from System Administration -> Support
RZ70 from NSP also fails JCo error. SLD_UC RFC itself works fine and the JCo RFC provider SLD_UC program is running
WEB AS & ITS connections work fine.
User authentication is from backend, NSP.
I think I have gone thru all the logs but could not resolve the issue.
I appreciate any help on this,
Victor

I tried to go thru the thread. I did not find any clue as why only server connectivity is failing. ABAP trial version is running fine and the NW trial version is working fine too. These run without crashing. I did a lot of customizing on the portal but dont see any issues except the System Connectivity. Like I mentioned I did UME configuration to point to NSP ABAP instance and I can log into the portal with user credentials that I use to login to ABAP. I can launch webgui etc without any issues.

Hi,
This JCO Exception caused by network problems, connection breakdowns, gateway problems, unavailability of the remote SAP system, etc.
What you can do is: Get the host of the SAP System from dev_jrfc.trc or the JRFC trace; ping the SAP system from command line; check routers, gateways, SAP systems
If an error has occurred on a lower communication layer, for example an RFC_ERROR_COMMUNICATION or RFC_ERROR_SYSTEM_FAILURE exception, have a look at the dev_jrfc.trc files. These files are written by JRFC and can be found in the directories j2ee/cluster/server* of the J2EE Application Server Installation.
Please check this blog and link:

NW2004s Connect to Message Server Host Failed - BW to Portals connection

Hi,
I am trying to connect a SAP BW NW2004s Patch 8 system to a NW2004s Portal. All of the checks in RSPOR_SETUP are successful.
However when I try to launch a query from Bex Query it fails with the following message.
"Connect to message server host failedConnect_PM TYPE=B MSHOST=SAPMSCR6 GROUP=webshop1_biw R3NAME=CR6 MSSERV=01 PCS=1"
The message server entry in the System Landscape object for the BW Server is "SAPMSCR6". Is this right?
I have searched for information about this and can't find anything. I am sure it is something basic. As anyone else resolved this issue or do they have an idea what might be causing the problem?
Any suggestions gratefully received.
Dave

I get same error message when i test the JCo Metadata connection, Model data connection works fine.
The message server value under WebDynpro content admin is created with right values as i checked with Basis person.
My service file in C:/windows/system32/drivers/etc has entries for both J2EE stack entry and ABAP stack (on remote server) entry with port numbers.
When i ping the ABAP (remote server) from my machine command prompt I get response.
I am running out of options. I really appreciate your inputs.
Ramesh

Hi, I think this might have todo with the fact that your Java stack wants to connect with a server from the same logon group called "PUBLIC".
Please make sure you added the same logon group "PUBLIC" to the ABAP Server. Try transaction SMLG.
Also as posted above the SLD needs this info aswell.
After using the transaction SMLG, log in and out 5 times in a row to your ABAP stack using SAP GUI. This might actually force an update to the SLD.

Robbert

Determining Message Server Host and Port information

Hi,
I am working on the NWDS creating a Java WD application and I was told which Netweaver system I should work on but I was not told the Message Server Host information neither the Port information. I ran transaction SM51 (right click->details)in the Netweaver system but the information it is not working. Even though I can telnet this server port if I go to the J2EE Engine window within the NWDS I do not see the green light. I just see "N/A". I also tried to deploy my application but I keep getting this message: "Cannot determine sdm host (is empty). Please configure your engine/sdm correctly".
Please advice,
Diego.

Hi Diego,
in order to see Message Server Host information and Port information go to SAP J2EE Engine start page: e.g. http://system-name:57100/index.html (use administrator pws).
Then click on System Information, here on the top you can read the Message Server Host and Port.
Hope this help you.
Bye,
Vito

Instant Messaging Server configuration failed after installation

Hi,
I have a problem with the configuration of Instant Messaging server as part Sun Java Communications Suite 6u2.
IM had been installed using commpkg install --altroot -installroot /opt/sun/comms2 (should run in cluster environment).
Running configure failed when looking for package SUNWiimin. Due to the altroot installation the package information resides under /opt/sun/comms2/var/sadm/...
Since configure is just a shell script those incorrect calls could be fixed (e.g. pkgparam -R /var/opt/sun/comms2 SUNWiimin instead of
pkgparam SUNWiimin.
Unfortunately configure calls com.sun.im.config.core.Configurator as a Java program. In this program IM_BASE seems not tobe set which leads to:
Executing command : null/sbin/impermissions inetuser r /var

RFC_ERROR_COMMUNICATION: Connect to message server failed

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.

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,

Hi,
Check that you have configured properly using the below document. And check the message server of R/3 is configured properly in the SLD.

J2ee connection error, "The Message Server did not respond within 60 sec"

Hi,
I am facing the error "The Message Server did not respond within 60 sec. Please check if the message server is running.." when connecting to J2ee through NWDS.
I am able to reach the index page via http://<ip address>:53500/index.html but yet unable to reach through NWDS.
I have tried various combinations of host and port names like:
Message Server Host : <ip address>, <host name>
Message Server Port : 3636, 3936
but still no luck.
I've also cross checked the value of message server port by navigating to http://<IP address>:53500/monitoring/SystemInfo too, it is 3636.
The telnet test (telnet <ip address> <port Number>) draws a blank window.
I know this problem has been posted again and again, but then I am unable to understand what is the solution to this.
Can someone please help me in resolving this issue?
Note: [link 1|Unable to Connect to the J2EE Server from Netweaver Developer Studio; & [link 2|Developer Studio:Exception:The message server did not respond within 60 sec; are already checked.

Hi Robin,
Although I still haven't received any info from my colleagues regarding the central instance..
Just a quick query, if we have NW04 we use 36** and if it is NW04S then we use 39** , is this the only difference for message server port?
If that is the case, as I mentioned earlier, I have tried both, and one gave me N/A(3936) while the other gave me 'message server did not respond' error(3636).
I have the message server host name & port , Enqueue Server Host name & Port and SDM PID and Port details with me..
Can this be anyway useful in establishing a connection?
Waiting for your inputs...
Best Regards,
Vinay

Unable to connect to message server through NWDS

Hello,
I am using NWDS for NW04s SP9.
I am configuring our correct message server host and port at the NWDS yet I see it as N/A and cannot deploy my applications. I tried configuring the NWDS with and without a proxy yet it didn't help.
What could cause that?
Thanks,
Vikas

I think you are not putting the correct message server port number. So you are not able to deploy your application in NWDS.
Pl. use Message Server Port = 3601
Message Server Host=<hostname>
Message server port should be 3600 + <Instance no.>

Changing message server port for ABAP+Java Instance

Hi,
We had change our message server port for the Java instance from 3607 to 3667.
We did this using the j2ee config tool. We also verified this information through the console config.
But when we look into system info URL using the URL as shown below, we still that the old message server port is being used. We have recycled the instance couple of times , but does not seem to help.
http://dfudsbw1.dfna.corp.dom:50700/sap/monitoring/SystemInfo
Any ideas where else we have to change the port no. for the message server

Hi guys,
I solved this on my own with documentation help from SAP.
I had to change the port no. in the Global dispatcher and Global server area as well.
Please see details from SAP below.
"Message Server: Changing Ports/Hosts shows which areas need to be adjusted if
the port or host of the message server changes. Ports are, of course, changed in the
instance profile of the Central Services instance. In the example, the port 3677 and
the HTTP port 8177 have been set, and the new host is called twdfxxx. You need to
use the Config Tool to set these values. For each instance, you need to maintain the
corresponding values for the Message server host and Message server port on the
Message Server and Bootstrap tab page. The connection details for dispatchers or
servers to the message server are maintained in the Cluster Manager. As shown in the
