Most likely a port in use issue.

Hello Reagan,

Now when I have changed the port no. I am able to view the administration page, but I am not able to ping the same.

Could you please provide the latest Web Dispatcher profile and the back end systems system numbers? Are you configuring Web Dispatcher for multiple back end system or for a single system?

Hi,

as far as I see, the binding of port still failes. Have you already checked this note?

421359 ICM: Binding ports < 1024 on Unix

Hello Gabriella,

The note 421359 has been followed and icmbnd has been modified as mentioned in the note.

But still getting this error while trying to ping . The url used for ping test is http://wd-sxx.xyz.com:8065/sap/public/ping?sap-client=150

Hi

In this thread, you provided the parameter  for ms/http_port http  as 8174



ms/http_port = 8174

But the trace log, it shows 8073 , how this is possible ?



[Thr 140551882446592] *** ERROR => IcmBindService: NiBuf2Listen failed for host xyz.com:8073

What is the correct instance #  ?,

From Web Dispatcher, try to telnet the MS port (telnet 8073 or telnet 8074, based on the correct instance # ) & ensure this port is reachable.

regards

Swami

Hi Mansi,

I can help with giving you some tips on finding the solution.

You quested the error log:

[Thr 140551867016960] *** ERROR => IcmConnClientRqCreate: No service for protocol HTTP started [icxxconn.c   3011]

[Thr 140551867016960] *** ERROR => IcmConnClientRqCreate() failed (rc=-1) [icrxx.c      7731]

I suggest, read the quoted OSS Note

and

search the

     SAP OSS Notes

     SCN

     Google

for the solution to this error:

     IcmConnClientRqCreate: No service for protocol HTTP started


Kind regards,


Andy.
