Connectivity problem between DBCI instance and Apps instance.

[Former Member]

Hi all,

We have encountered a problem. Whereby our DBCI instance is having connectivity issue with one of the APPS instance.

In our environment :-

SAP R/3 4.7x200 , Oracle 10G, HP-UX 11.31

1 DBCI instance.

2 application instance.

In the SM51, we can see all the instance is active, but when we do a RFC test one of the Apps instance will failed.

The error message we get from the RFC test is :-

ERROR connection to host localhost, service sapgw17

timed out

LOCATION SAP-Server db09_EN1_17 on host db09 (wp 0)

DETAIL NiPConnect

COMPONENT NI (network interface)

COUNTER 128

MODULE nixxi.cpp

LINE 1109

RETURN CODE -12

SUBRC 0

RELEASE 640

TIME Wed Jan 5 23:27:58 2011

VERSION 37

Error message from system log:-

"S0T NiConnect Unsuccessful, Return Code: -0012

S0R > Host: localhost

S0S > Service: sapgw17

We didn't get any error message except RFC test failed and some system log.

How can we further investigate this problem? It happen at our PROD environment. i have shutdown the apps instance because it has slowdown our system performance.

Thanks.

Are you able to see wps of the instance when you are double clicking on the app instance which gives the error?

Please try followings command

From DBCI instance : telnet <app host name> sapgw17

From App Instance : telnet <dbci host> sapgw17
