RFC Error

[Former Member]

Hi Everyone,

I have some problems with aplication which was build to retrieve data from SAP boxes. The problem is that when i am tring to connect to some of the SAP boxes i get the error:

Warning: RFC Error Info : Group : 102 Key : RFC_ERROR_COMMUNICATION Message : Connect from SAP gateway to RFC server failed Connect_PM GWHOST=xxxxxxxxxx, GWSERV=sapgw00, ASHOST=xxxxxxxxxxxx, SYSNR=00 LOCATION SAP-Gateway on host xxxxxxxxxxx / sapgw00 ERROR Gateway not connected to local R/3 TIME Mon Jan 15 13:56:25 2007 RELEASE 640 COMPONENT SAP-Gateway VERSION 2 RC 726 MODULE gwr3cpic.c LINE 5205 COUNTER 2 in

And that's it. The code i am using is working for some of the SAP boxes and for some i get the message above. What can be the solution for this error "ERROR Gateway not connected to local R/3 TIME" as i stucked completely and google doesn't help me very much .

If anyone had similar problem i would be more than happy if you would give me any clue.

Regards,

Filip

I'm facing the same problem using JCO 1.2.8 on one machine and the latest SAP NetWeaver CE Trial Version on another one, both with the latest VC++ 2005 DLLs:

Filip, could you solve the issue?

BTW, there is no firewall between the systems.

Any hint would be very valuable.

Thanks,

Hi Stephan,

As Anton has said the issue was with the name server. I have used diffrent name of the server and everything went cool. Right now if i face such a problem i just change the name or use an ip. In my case i have found that couple of ip take me to the same instance of sap so even when one of the ip give me an error i can just change to the other.

Stephan i recomend you to play with the server names. Cannot help more.

IMHO this is a firewall problem.

would the firewall settings be correct but the ICF being down you would get a timeout error.

second guess: nameserver problem.
