WebGUI issue: HTTP 400. dev_icm referencing an old server (system copy)

[#1]

Hi all

I'm trying to set up WebGUI for a new system (system copy via export/import) and I've followed all the usual steps i.e.

set profile parameters:

icm/server_port_0 PROT=HTTP,PORT=8000

icm/host_name_full <Full Qualified Domain Name>

Transaction SICF, services started:

/sap/public/bc/its/mimes

/sap/public/bc/ur

/sap/bc/gui/sap/its/webgui

Transaction SE80 locate from the menu, Utilities --> Settings-->Internet Transaction Server (Tab)-->Publish

(Tab) and set “On Selected Site” = INTERNAL.

This restricts the publication in the next step to the integrated (internal) ITS.

In SE80 only, Locate the Internet Services: SYSTEM and WEBGUI.

Publish these services with the Context Menu -> Publish -> Complete Service

Also ran SIAC_PUBLISH_ALL_INT to republish anything else required.

Browsing to http://<server>:<icmport>/sap/bc/gui/sap/its/webgui/ presents the login page - all good so far.

However, when I log in, I get a "Service cannot be reached" error, "HTTP 400 - Session not found".

This is a 701 system (so note 1301591 doesn't apply - SICF_SESSIONS transaction doesn't exist)

I've just checked dev_icm trace file and see the following error:

*** WARNING => Connection request from (7/8/0) to host: <oldservername.domain.com>, service: 5720 failed

(NIEHOST_UNKNOWN)

Note that <oldservername.domain.com> is NOT my server name, but I think the name of the original system (remember this is a system copy).

I've searched through the profile parameters, and also checked table HTTPURLLOC, but I can not see any references to this old server name.

Where could this be defined/how do I remove it/update with the correct server name?

Thanks!

I can see that the ICM host name buffer has the incorrect server name in it.

If I clean this out (from SMICM or from SM51 - reset all) then it disappears, but as soon as I use the WebGUI again it reappears.

At one point, the correct hostname DID appear in the buffer - but the old incorrect one was also there - and the WebGUI still didn't work.

Did another reset, republished services etc, and back to just the old one in there.

Upped the trace level for ICM to 3, but nothing useful reported - still can't see where it gets this old server name from.

I also checked 773830 - FQHN determination in ICM and I can see SAPLOCALHOSTFULL is set and showing the correct name (by running SE38 RSPARAM).

Any other ideas where this could be coming from?

Hi Ross,

Can you share the kernel (7.21) patch level you are using?

Thank you,

721 patch 402

Hello Ross,

You can also try some tests suggested in this wiki page.

Hello Ross,

I tried to find kernel corrections from pl 402 to 714, but no match for hostname cache or similar.

I think this is really a cache problem (something is telling me that might be related to HTTPURLLOC, even though you have already ruled out this possibility).

Thanks Cris, will take a look
