Issue#5 HTTP Error 500.0 Internal Server Error
Environment：
OS:Windows Server 2012R2
Siebel Version: 16
Issue:
- The Gateway and Siebel server is installed and running. The SWSE also installed without any issues.
- But accessing Thin application URL gives below error
“HTTP Error 500.0 Internal Server Error
The page cannot be displayed because an internal server error has occurred.”
Cause:
Microsoft Windows Server 2008, 2012 R2 with SP1 or above (64-bit) supports Microsoft IIS 7.5 (32-bit compatibility). By default, IIS 7.5 will use 64-bit compatibility, which is not supported by Siebel applications. Therefore, the application throws HTTP Error 500.0 Internal Server Error.
Solution:
We have to enable 32-bit mode on ISS 8 in Windows Server 2012 r2 to make it compatible with Siebel application.
- Open Internet Information Services (IIS) Manager:
- On the taskbar, click Server Manager, click Tools, and then click Internet Information Services (IIS) Manager.
- In the Connections pane, expand the server name, and then click Application Pools.
- In the Actions pane, click Set Application Pool Defaults…
- On the Application Pool Defaults dialog box, specify your desired options.
enable32BitAppOnWin64 |
Optional Boolean attribute.
When true, enables a 32-bit application to run on a computer that runs a 64-bit version of Windows. The default value is |
|---|
- When you have finished specifying your settings, click OK.
- Restart your machine
