Increase the JVM Heap Size on 32-Bit Windows Server Computers
You can edit the Windows registry to increase the JVM heap size on a 32-bit Windows Server computer on
which View Connection Server is installed.
IMPORTANT Do not change the JVM heap size on 64-bit Windows Server computers. Changing this value might
make View Connection Server behavior unstable. On 64-bit computers, the View Connection Server installer
sets the JVM heap size to accord with the physical memory. If you change the physical memory on a 64-bit
View Connection Server computer, reinstall View Connection Server to reset the JVM heap size.
On a 32-bit computer, if you increase the JVM heap size and reinstall or upgrade the View Connection Server
software, you must increase the JVM heap size again. This value is reset each time the View Connection Server
software is reinstalled or upgraded.
Procedure
1 On the Windows Server computer, start the Windows Registry Editor.
a Select Start > Command Prompt.
b At the command prompt, type regedit.
2 In the registry, locate the subkey and click JvmOptions.
HKEY_LOCAL_MACHINE\SOFTWARE\VMware, Inc.\VMware VDM\Plugins\wsnm\tunnelService\Params
3 Click Edit > Modify.
A Windows dialog box displays an entry like the following one.
-Xms128m -Xmx512m -Xss96k -Xrs -XX:+UseConcMarkSweepGC
-Dsimple.http.poller=simple.http.GranularPoller
-Dsimple.http.connect.configurator=com.vmware.vdi.front.SimpleConfigurator
4 Edit the -Xmx parameter to have the value -Xmx1024m.
The dialog box displays the following entry.
-Xms128m -Xmx1024m -Xss96k -Xrs -XX:+UseConcMarkSweepGC
-Dsimple.http.poller=simple.http.GranularPoller
-Dsimple.http.connect.configurator=com.vmware.vdi.front.SimpleConfigurator
5 Click OK and exit the Registry Editor.
6 Restart the Windows Server computer.
Configure the System Page-File Settings
You can optimize the virtual memory on the Windows Server computers on which your View Connection
Server instances are installed by changing the system page-file settings.
When Windows Server is installed, Windows calculates an initial and maximum page-file size based on the
physical memory installed on the computer. These default settings remain fixed even after you restart the
computer.
If the Windows Server computer is a virtual machine, you can change the memory size through vCenter Server.
However, if Windows uses the default setting, the system page-file size does not adjust to the new memory
size.
