Sizing the Java Virtual Machine
The View Connection Server installer sizes the Java Virtual Machine (JVM) heap memory on View Connection
Server computers to support a large number of concurrent View desktop sessions. However, when View
Connection Server runs on a 32-bit Windows Server computer, the View Secure Gateway Server component
is configured with a limited JVM heap size. To size your deployment adequately, you can increase the JVM
heap size on 32-bit computers.
On a 64-bit Windows Server computer with at least 10GB of memory, the installer configures a JVM heap size
of 2GB for the View Secure Gateway Server component. This configuration supports approximately 2,000
concurrent tunnel sessions, the maximum number that View Connection Server can support. There is no benefit
in increasing the JVM heap size on a 64-bit computer with 10GB of memory.
N On a 64-bit View Connection Server computer, 10GB of memory is recommended for deployments of
OTE
50 or more View desktops. Configure less than 10GB of memory for small, proof-of-concept deployments only.
If a 64-bit computer has less than 10GB of memory, the installer configures a JVM heap size of 512MB for the
View Secure Gateway Server component. If the computer has the required minimum of 4GB of memory, this
configuration supports approximately 500 concurrent tunnel sessions. This configuration is more than
adequate to support small, proof-of-concept deployments.
If you increase a 64-bit computer's memory to 10GB to support a larger deployment, View Connection Server
does not increase the JVM heap size. To adust the JVM heap size to the recommended value, reinstall View
Connection Server.
On a 32-bit Windows Server computer, the default JVM heap size is 512MB for the View Secure Gateway Server
component. This JVM heap size can support approximately 750 concurrent tunnel sessions. To support more
than 750 sessions, the computer must have at least 3GB of memory and the JVM heap size should be increased
to 1GB. A JVM heap size of 1GB supports 1,500 concurrent tunnel sessions, the maximum number that View
Connection Server can support on a 32-bit computer.
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.
I Do not change the JVM heap size on 64-bit Windows Server computers. Changing this value might
MPORTANT
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, you must increase the JVM heap size each time you install or upgrade the View
Connection Server software.
