Reg: SAP Router RFC Connection Error

former_member216430 · ‎04-25-2014

Dear Expert,

I am facing one connectivity issues from RFC, I tried SAPOSS RFC connection Errors, But earlier it was working fine and now could not connecting,

I checked Service.msc entries, Everything is fine and all.

FYI I attached Router log and RFC Connection Error screen shots.

Hi

Apart from other replies, please also check that you don't any any port blockage b/w your router and yoru SAP Server.

You can telnet and check the same. Check that your entry for SAP server also exits in SAPROUTER.

Regards,

Deepanshu Sharma

Hi,

Also, please update your SAProuter to the current version:

http://service.sap.com/swdc

-> SAP Support Packages and Patches
    -> Download Catalog
      -> Additional Components
        -> SAP Kernel
          -> SAP KERNEL 64-BIT UNICODE
            ->

see also SAP Note 1486956 for further details.

Thanks

Vikram

Hi,

ERROR => NiBufIProcMsg: hdl 25 received rc=-17 (NIESNC_FAILURE) from peer [nibuf.cpp    2123]

as per the note 63342 - List: NI error codes,

the rc=-17, deals with


#define NIESNC_FAILURE -17 /* Error in the SNC shift */
                          /* in the saprouter ==>

check inbound and out bound snc settings as mentioned here

https://websmp108.sap-ag.de/saprouter-sncdoc
