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.

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.

Note

On a 64-bit View Connection Server computer, 10GB of memory is recommended for deployments of 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.

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.
