Environment

Directory and Resource Administrator 7.x
Directory and Resource Administrator 8.x

Situation

Is Directory & Resource Administrator 3-GB-aware?

Does DRA run with the /LARGEADDRESSAWARE switch?
How do I enable the /3GB switch for DRA?

Resolution

For Directory and Resource Administrator's (DRA) versions 8.1 SP1 and prior, the McsAdminService.exe is not created with the /LARGEADDRESSAWARE switch and hence, it is not 3 GB aware.

Beginning in DRA version 8.1 SP2, DRA has enabled the 3 GB switch in the Administration server.

Note:

  • By enabling the 3 GB switch in 32-bit versions of Microsoft Windows, DRA now uses a 3 GB virtual address space, with the kernel components using only 1 GB.
  • By enabling the 3 GB switch in 64-bit versions of Microsoft Windows, DRA now uses a 4 GB virtual address space, with the kernel components using an infinite amount of virtual address space.

To set the 3 GB switch in the Administration server:

  1. Right-click My Computer and select Properties. The System Properties dialog box displays.
  2. Click the Advanced tab.
  3. In the Startup and Recovery area, click Settings. The Startup and Recovery dialog box displays.
  4. In the System startup area, click Edit. This opens the Windows boot.ini file in Notepad.
  5. In the [Operating Systems] section, add the following switches to the end of the startup line that includes the /fastdetect switch: /3GB
  6. Save the changes and close Notepad.
  7. Click OK two times to close the open dialog boxes, and then restart the computer for the change to take effect.

Note: To take advantage of the 3 GB switch, these steps will need to be performed on each DRA server.

Additional Information

Formerly known as NETIQKB70658

Operating systems using Microsoft Windows NT technology provide applications with a 32-bit virtual address space comprising 4 GB of virtual memory. The address space is split so that the application can access 2 GB of address space and the Microsoft Windows operating system accesses the remaining 2 GB .

By enabling the 3 GB switch, 3 GB of virtual address space is available to an application that uses IMAGE_FILE_LARGE_ADDRESS_AWARE in the process header. To enable the 3 GB switch in the Administration server, you need to include the 3 GB switch in the Boot.ini file.
