How the Resource Hosting Subsystem Plug-In Works

The CA Access Control installation process runs the Resource Hosting Subsystem plug-in during a CA Access Control installation, and the coexistence utility runs the Resource Hosting Subsystem when a customer executes the utility. The Resource Hosting Subsystem plug-in scans the computer for the Cluster Service Element, as follows:

  1. Checks if the operating system is Windows Server 2008 or later.

    If the OS is of an earlier Windows version, the plug-in terminates.

  2. Checks if the Cluster Service Element is installed on the computer.

    If the Cluster Service Element is not installed, the plug-in terminates.

  3. Creates the following SPECIALPGM resource of type PBF: 
    system_drive:\Windows\Cluster\rhs.exe

Note: The response file determines the default action that the coexistence utility performs at prescribed stages (what to do before CA Access Control installation, after CA Access Control installation, and so on).
