Oracle Fail Safe Manager Display Issues with Windows

On Windows 8 and Microsoft Windows Server 2012 systems, Oracle Fail Safe Manager may not display dialog boxes correctly. Windows may not display the graphical user interface (GUI) elements with the correct layering or z-order.

For example, if you click a drop-down list in a dialog box, the dialog box will drop behind its parent window, leaving the drop-down list displayed over the parent window instead of the dialog box that it belongs to. Similarly, in a dialog box with a tooltip, if you move your cursor over the window, the tooltip is displayed but the dialog box will drop behind its parent window.

This issue exists in previous versions of Windows, but with the upgrade of Microsoft Management Console (MMC) to .NET 4.0 this issue is now seen in MMC applications that use Microsoft Windows Presentation Foundation (WPF) to create forms. The new Oracle Fail Safe Manager is MMC based and uses the WPF in most windows and dialog boxes. Thus, the new Fail Safe Manager is likely to encounter the z-order issues.

Microsoft has resolved this problem in Microsoft .NET Framework 4.5.1 which is included in Windows Server 2012 R2 and Windows 8.1. Customers can download that release of .NET and install it on Windows Server 2012 or Windows 8 systems. After installing .NET 4.5.1 it is then necessary to create a configuration file that will enable the correct behavior in applications, such as Microsoft Management Console (MMC), that may mix Windows Forms and Windows Presentation Foundation (WPF) in the same application.

To fix this problem for the Fail Safe Manager create a configuration file named "mmc.exe.config" and store it in the system directory that contains MMC.exe, typically "C:\Windows\System32". Use the following for the content of the configuration file.

    <?xml version="1.0" encoding="utf-8" ?>
            <add key="UseSetWindowPosForTopmostWindows" value="True" />

To avoid these issues, install Oracle Fail Safe Manager on a Microsoft Windows Server 2008 or a Microsoft Windows 7 system and remotely manage clusters from that system.
