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?

Dear Gregor,

Your point is valid, I tried by giving the name of my machine in RZ70 in SAP R/3, I get some other error.

Could you please tell me where exactly you want me to try the changes. It would be nice if you can guide me in steps.

THanks!

Hello,

you told us that the R/3 Server is on another machine. If you want to register the R/3 system into the SAPNetWeaver04SneakPreviewSlimSP11 SLD you have to provide the IP or Hostname of the Server where you have installed the SneakPreview. If you create the System manually you have to provide the IP or Hostname of the R/3 system. As I can see from your error messages you've always used localhost or its equivalent 127.0.0.1.

Regards

Gregor
