System Log errors with SLD_UC RFC fail

Hi,

I see some runtime errors everyday in my system log as below:

Operating system call SiPeekPendConn failed (error no. 10061)

Communication error, CPIC return code 017, SAP return code 236

> CPI-C function: CMINIT(SAP)

When i tried to check some details during the time of errors, I see that the job "SAP_SLD_DATA_COLLECT" is running during this time. The job succeeds everyday without any errors reported. But, when i drill down to details of this job, i see that it is trying to connect using the RFC connection SLD_UC which is failing with a gateway error "SAP Gateway connection failed....."

The trace file dev_rd gives the following information:

Mon Nov 24 06:09:56 2008

The error says that the partner on a specific service is not reacheable. How to check this?

Please help me to resolve this.

Thanks

Vijay

    Hi Vijay,

    the error comes from the network interface :

    NiPConnect2: SiPeekPendConn (10061: WSAECONNREFUSED: Connection refused)

    Connection refused means that it is not possible to connect to the service from

    a network point of view. The problem could be :

    - the host can not be reached

    - the service on the specified tcp/ip port can not be reached

    The item which can not be reached is host cambsvr10, service sapgw02.

    Pls try the following commands :

    1.) ping cambsvr10

    2.) telnet cambsvr10 sapgw02

    Regarding point 2.) : when the port is open you will get an empty screen -> ok. If you

    get an error you will need to fix the error, usually the port is not open, or the wrong

    port is specified, or the entry is missing in the service file -> <port> sapgw02.

    Hope this helps.

      Hi,

      Thank You very much. The instructions are very clear. I have asked my network team to look into this.

      I will let you know the status once we have an update.

      Thanks
