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.


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.


On the Windows Server computer, start the Windows Registry Editor.


Select Start > Command Prompt.


At the command prompt, type regedit.


In the registry, locate the subkey and click JvmOptions.

HKEY_LOCAL_MACHINE\SOFTWARE\VMware, Inc.\VMware VDM\Plugins\wsnm\tunnelService\Params


Click Edit > Modify.

A Windows dialog box displays an entry like the following one.

-Xms128m -Xmx512m -Xss96k -Xrs -XX:+UseConcMarkSweepGC 

Edit the -Xmx parameter to have the value -Xmx1024m.

The dialog box displays the following entry.

-Xms128m -Xmx1024m -Xss96k -Xrs -XX:+UseConcMarkSweepGC

Click OK and exit the Registry Editor.


Restart the Windows Server computer.
