4.2.1 Notes on Operating HDLM GUI Windows

This section provides important notes for operating HDLM GUI windows.

The HDLM GUI cannot start when all of the following conditions exist:

 The operating system of the host is Windows Server 2003 with SP1 or later applied.

 Data Execution Prevention (DEP) functionality is enabled on the host.

 HDLM GUI is started by using the JRE that is bundled with the HDLM product (JRE 1.3.1

provided by Sun Microsystems, Inc.) on the host.

When all of the following conditions exist, exclude the Java Runtime Environment that HDLM

GUI is using from being subject to DEP (data execution prevention), by performing the

following procedure:

1. Choose Start, Settings, Control Panel, double-click System. The System Properties

window is displayed.

2. Select the Advanced tab. Click the Settings button under Performance. The

Performance Option window is displayed.

3. Select the Data Execution Prevention tab.

4. Select the check box beside java. If java is not displayed add it by clicking the Add

button and then specify the following file in the File Selection dialog box:

HDLM-installation-folder\jre\bin\java.exe.

Clicking Open button then adds java.

5. Complete the process by clicking the [OK] button. The Java Runtime Environment the

HDLM GUI is using is excluded from being subject to DEP (data execution prevention).

 If you do not install SP1 or later on Windows Server 2003 (IPF), the HDLM GUI might end

abnormally when you start or operate the HDLM GUI. If this problem occurs, change the

link destination of the shortcut for starting the HDLM GUI as shown below:

– Before changing the link destination

"HDLM-installation-folder\bin\dlmgui_launcher.exe"

– After changing the link destination

"HDLM-installation-folder\jre\bin\javaw.exe" -Xint -classpath

"system-drive-name:\Program

Files(x86)\HITACHI\HNTRLib2\classes\hntrlib2j.jar;HDLM-

installation-folder\bin\DLMLocal.jar" dlmgui.DLMGUI

Note that if you change the link destination of the shortcut, the following

phenomena occurs:

– The HDLM GUI will take 1.5 times longer to start.
