Hi experts,
I get the following error when i ping through JCO destinations on portals.
com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: Connect to SAP gateway failed Connect_PM TYPE=B MSHOST=imtsapdev01 GROUP=CLUST R3NAME=DMI MSSERV=sapmsDMI PCS=1 LOCATION CPIC (TCP/IP) on local host with Unicode ERROR partner '127.0.0.1:3310' not reached TIME Tue Jan 27 16:39:54 2009 RELEASE 700 COMPONENT NI (network interface) VERSION 38 RC -10 MODULE nixxi.cpp LINE 2823 DETAIL NiPConnect2 SYSTEM CALL connect ERRNO 10061 ERRNO TEXT WSAECONNREFUSED: Connection refused COUNTER 1
However my JCO destinations were working perfectly until recently. I checked on the logon group. I have one called CLUST, which i use for this purpose.
I have also checked both service files and they have the following for the ECC server im connecting to.
3610 because its system number 10 i am connecting to.
sapmsDMI 3610/tcp
From the JCE destinations screen i cannot even ping the server. I can though when i log on to the server through remote desktop.
thanks and regards

as a reply to nishants posts.
goto rz70
give hostname -->
service --> sapgw00 (sapgw(instance number)
execute it
click on yes
check rfc call (success or failed)
I have done this. i left hostname as "blank" gave service as "sapgw10"
The following is what i got as the output.

1: IMTSAPDEV01_DMI_10 : Event-controlled job already exists; scheduling not necessary
so i guess its not successful. when i look at rz70 of a server where this works correctly its not succsessful either
if it is success then technical system name will be in sld
to restart sld --> /sld --> administration --> stop server --> restart server
or check in VA --> SLD data supplier value --> Runtime
I checked this and i do not see aa problem. you have configuration status as valid and send reult as Success
Services file is locted on OS level of R3 system--> Goto --> Start --> Run -> (type)Drivers(enter) --> etc -> (here is services file)
check ur r/3 server entry is there or not,
I have the followng in the service file for the server
sapmsDMI 3610/tcp
if not add it
Something is wrong with the gateway host definition. It is going to localhost on the portal server, not the real location. That is why you see the
'127.0.0.1:3310'
part of the message...

Hi Michael,
thanks for you're quick response. when you say gateway host defiition which server are you talking about? the R/3 server portal is connecting to or the portal server itself. I'm a bit confused with this.
Also where can i set this?
I have another R/3 system which portal can connect to seamlessly.The system where i get an error also was working without an issue until recently when it just stopped working. So im thinking its got something to do with the R/3 server.
thanks and regards,
dilanke
Hi Michael,
I've checked the JCO destination and there is nowhere lacalhost is assigned. its assigned a message server which is the technical system on which R/3 runs on.
I've also checked the technical system and the message server is pointing to the R/3 server. nowhere is localhost used. actually thinking about it im not sure why we get a 127.0.0.1 value there at all.
thanks,
dilanke
hi,
Look in following link for detail analysis for this error.
http://help.sap.com/saphelp_nw04s/helpdata/en/22/042a58488911d189490000e829fbbd/frameset.htm
You can try to increase JCo maximum connection no. and then restart your server..

Hi Experts,
when ilook at the remote gateway properties in SMGW this is what i see on the R/3 server. ive looked at my other system which i can connect to and there isnt much of a difference in the parameters. How can test this to see if it works?
