[Thr 5] *** ERROR => IcmJ2EEScheduleFunc: Connection to 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


The HTTP communication of this application server is not functioning correctly.

When calling the method


the exception


was triggered.

The short text for this exception reads as follows:

Contact your system administrator


Can someone please help?

Thanks in advance.

    >>>>, service: 8000 failed (NIEHOST_UNKNOWN)

    try putting IP instead

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

      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.

    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.

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