Tuning the System Parameters of the Admin Server

This section explains the procedure for tuning the system parameters of the admin server.

It is necessary to tune the system parameters of the admin server before installing the Resource Orchestrator manager.

The system parameter to tune and the value to specify are as follows.

Desktop heap
Check the value of the desktop heap. If the value is less than 3328, change it to 3328.

Procedure

Perform the following procedure in Windows to change the value of the desktop heap.

Open the Registry Editor.

Click [Start]-[Run]. Enter "regedit", and then click the [OK] button.
Move to the [SubSystems] key.
Move to the following key on the [HKEY_LOCAL_MACHINE] tree.
```
\SYSTEM\CurrentControlSet\Control\Session Manager\SubSystems
```
Select [Windows].
Open the [Edit] menu and select [Modify].
Change the value for [SharedSection] to increase the size of the desktop heap.
If the value of the third value (zzzz) is less than "3328", change it to "3328". The unit of the third value (zzzz) is KB.
```
SharedSection=xxxx,yyyy,zzzz
```
* Note: It is not necessary to change the first value (xxxx) or the second value (yyyy) in order to operate Resource Orchestrator.
Restart the system.

Note

Improper modification of the registry using the Registry Editor could cause serious problems. In the worst-case scenario, it could be necessary to reinstall the OS in order to resolve such problems.

Before modifying the registry, be sure to take the proper precautions, such as backing up the system in advance.
