SAP NW RFC SDK throws RFC_INVALID_PARAMETER when running sample programs?

Hi there,

I have just downloaded the latest version of the SAP NW RFC SDK (NWRFC_7-20004565.SAR) for Linux 64 bit from the Service Marketplace and am trying to run the demo programs.

NOTE: I removed the "sapnwrfc.ini" from the current directory so that it would not be used at all..

Also note that I can use the OLD RFC SDK and connect happily to the same SAP system I am trying to connect to below using the SAP NW RFC SDK....so I definetly have the cirrect settings.....

So I compiled a CLIENT test program like:

gcc -m64 -Wall -g ./sflightClient.c -I/home/lynton/Desktop/nwrfcsdk/include -L/home/lynton/Desktop/nwrfcsdk/lib -lsapnwrfc -lsapucum -o ./sflightClient

And then passed in VALID paramters to an SAP system I have access to and I keep getting RFC_INVALID_PARAMETER even though I have not touched the code below in the sflightClient.c program

     loginParams[0].name = cU("ashost");     loginParams[0].value = argc > 1 ? argv[1] : cU("hostname");     loginParams[1].name = cU("sysnr");     loginParams[1].value = argc > 2 ? argv[2] : cU("50");     loginParams[2].name = cU("user");     loginParams[2].value = argc > 3 ? argv[3] : cU("user");     loginParams[3].name = cU("passwd");     loginParams[3].value = argc > 4 ? argv[4] : cU("******");          loginParams[4].name = cU("client");     loginParams[4].value = argc > 5 ? argv[5] : cU("800");     loginParams[5].name = cU("lang");     loginParams[5].value = cU("EN");

I have also tried the stfcDeepTableServer.c program....and there I put in VALID settings....(and made the parameters UPPERCASE just like the settings in the "sapnwrfc.ini" file....

serverCon[0].name = cU("PROGRAM_ID");     serverCon[0].value = cU("TEST_SERVER");        serverCon[1].name = cU("GWHOST");     serverCon[1].value = cU("test.server");     serverCon[2].name = cU("GWSERV");     serverCon[2].value = cU("sapgw00");     repoCon[0].name = cU("CLIENT");     repoCon[0].value = cU("000");     repoCon[1].name = cU("USER");          repoCon[1].value = cU("BCUSER");     repoCon[2].name = cU("PASSWD");     repoCon[2].value = cU("minisap");     repoCon[3].name = cU("LANG");          repoCon[3].value = cU("EN");     repoCon[4].name = cU("ASHOST");     repoCon[4].value = cU("test.server");     repoCon[5].name = cU("SYSNR");     repoCon[5].value = cU("00");        repoCon[6].name = cU("TRACE");     repoCon[6].value = cU("3");

I have the UUIDD daemon running perfectly on my box, but yet I keep getting this RFC_INVALID_PARAMETER regardless if I just test the SERVER REGISTRATION or a simple client connection.

I am connecting to a NON unicode system but that would not make a difference.....

Any idea what would cause this? Any help would be greatly appreciated ....

Thanks

Lynton
