Error on JCO connection

[former_member188321]

Hi,

My SAPNetWeaver04SneakPreviewSlimSP11 is installed on local system, but SAP R/3 server is on some other machine(xSAP).

I run transaction RZ70 on R/3 system, with SLD bridge gateway system:

Host: localhost

service: sapgw00

But when I run it, SLD data collection successful.

When It used RFC desctination SLD_NUC, It gave error "RFC call failed: com/sap/util/monitor/jarmTaskMonitor. Unable to delete existing periodic SLD job; SLD job may start at incorrect time...."

So in Technical Landscape, I manually created ABAP system entry.

Afterwards, I successfully created JCO destination. But when I test the JCO destination, it gives error:

"com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: Connect to SAP gateway failed Connect_PM GWHOST=127.0.0.1, GWSERV=3300, ASHOST=127.0.0.1, SYSNR=00 LOCATION CPIC (TCP/IP) on local host ERROR partner not reached (host 127.0.0.1, service 3300) TIME Tue Jan 17 14:15:03 2006 RELEASE 640 COMPONENT NI (network interface) VERSION 37 RC -10 MODULE nixxi_r.cpp LINE 8605 DETAIL NiPConnect2 SYSTEM CALL SiPeekPendConn ERRNO 10061 ERRNO TEXT WSAECONNREFUSED: Connection refused COUNTER 1

"

What could be the reason?

Yashpal, these settings I am making in SAP R/3. So, it is the same affect as the error I mentioned.

Yes Rohit, I already have all those settings mentioned by you. Moreover, I guess sapms setting plays role in messaging, but my error is not replated to that. Please analyze the problem and suggest me a some more solution.

Thanks.

Hi,

Is your SLD configured correctly

go to

http://<hostname>:50000/

go to webdynpro->content administrator and check sld connections

See the message at the bottom

If it is not successful configure your sld correctly

You have to set the service name in the path as shown below

c:\winnt\system32\drivers\etc\services file.

Make sure that the service name and port no are correctly copied there

It should be in the format

sapms<SID> 3600/tcp

Hope this helps you

Regards

Rohit
