ITS logon failure - help-

Former Member

We are trying to perform a disaster recovery test and after restoring the W2K agate and wgate servers, the admin logon pane will not display. It looks like the servers were restored without any problems but we get a page not found. When we reviewed the IIS and home directories we found nothing there. The functioning production systems are the same way.

What we need is an explanation on how the below url translates into the logon pane within ITS. Also, are there any traces that can be used to help indicate where the tripup is?

Thanks

Hello Rich,

you have to narrow the error by:

  • checking the IIS error log

  • checking the event log

  • checking the wgate traces

  • taking out the wgate

It seems like a general IIS issue, make sure that IIS can deliver static pages and then proceed with the wgate.

Explanation wgate dependencies in IIS.

  • wgate is both an ISAPI filter and extension

    • filter:

IIS admin/webservers/properties/(tab)ISAPI filters

There should be a "WGate" pointing at:

C:\Program Files\SAP\ITS\6.20\programs\wgate.dll

    • extension:

Under your webserver there should be a virtual directory "SAP-WGate-Scripts" pointing at:

C:\Program Files\SAP\ITS\6.20\programs

  • The wgate.conf resides beside wgate.dll and is just a bridge to tell the wgate where its registry ItsRegistryWGATE.xml is located.

  • when the wgate.dll is loaded (assuming all dll dependencies are there and it CAN be loaded) it will display an event saying "wgate is being loaded".

  • If the ITS registry is OK then WGate will start tracing:

C:\Program Files\SAP\ITS\6.20\WGATE\traces

So how to proceed:

  • take out the wgate ISAPI

  • make sure that your IIS is running and serving pages without the HTTP 500

  • put in the WGate ISAPI again

  • check the event log for "wgate is being loaded"

  • eventually check for IIS events

  • eventually check for IIS errors in the log

  • check if wgate traces are being written

  • eventually check the wgate traces.

Hope it helps, regards,

Fekke

Hi Rich,

Do you get an IIS webserver error page or an ITS error page when you try to start the Admin Tool? Please post the exact error message.

What happens if you leave out the "scripts/wgate/admin/!" at the end of the URL? Which error message do you get?

Best regards,

Henning

I believe that it is an IIS error, page not found. When I leave out the scripts/wgate/admin/!, I get an not authorized error.

Can you explain how this url gets to the final html pane?

thanks

Are there any good SAP docs on ITS architecture?
