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.

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.

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.
