I am building an http conn from XI to ECC6 for ABAP proxy

On Connection Test, I get the error - ICM_HTTP_CONNECTION_FAILED

On running the trace in SMICM, I get the following:

-


[Thr 5] *** ERROR => Connection request from (-1/65535/0) to host: srpidev.srhouse.com, service: 8000 failed (NIEHOST_UNKNOWN)

[Thr 5] *** ERROR => IcmJ2EEScheduleFunc: Connection to srpidev.srhouse.com:8000 failed - please check host configuration (-8)

-


I get the foll on running the report: SPROX_CHECK_HTTP_COMMUNICATION

-


HTTP communication contains errors (see long text for diagnosis)

Message no. SPRX086

Hi,

>>>>srpidev.srhouse.com, service: 8000 failed (NIEHOST_UNKNOWN)

try putting IP instead

does your ERP have access to XI on port 8000 ? (no firewalls issues)?

Hello Michal,

Thanks for your response.

Part of this problem has been solved right now...the http port on the R/3 server is 8002 and not 8000!!

Changing the port solved my problem from XI to R/3.

But the R/3 to XI error persists with the same behaviour. I have checked with BASIS, no firewall exists in between.

I have used the ip add while creating the http conn....do I have to change this elsewhere?

Hello All,

We have finally solved the second part of the problem yesterday (R/3 to XI conn error).

What happened is someone had previously configured http proxy in the R/3 system:

SM59 > Extras > HTTP proxy configuration

I guess this is required if there is a firewall/proxy between the R/3 and XI systems. But since in this case, there is no proxy in between, this config was not required.

Once we deleted the proxy configuration (global settings/http log/https log) and the unchecked all the check boxes, the http conn worked.

Thanks to all those who replied to this thread. I have awarded points to the helpful answers.

Regards,

Prasad

hi,

not sure how -- but once when we got this error and nothing worked out, restart of the server did the trick...

thanks,

Check in sm59 that the RFC destination configuration is correct. For that check the the smicm -> Menu Goto Services -> Hostname and port.

Also check that ur http service is running in sicf.
