VMware View Manager 4.5 Installation Manual page 61

Prerequisites
Calculate the number of ephemeral ports to configure on the Windows Server computer. See
Number of Ephemeral Ports,"
Modify the Windows registry value only if the resulting number of ports is greater than 4,000 on Windows
Server 2003 or greater than 16,000 on Windows Server 2008.
Procedure
1 On the Windows Server computer, start the Windows Registry Editor.
a Select Start > Command Prompt.
b At the command prompt, type
2 In the registry, locate the correct subkey and click Parameters.
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters
3 Click Edit > New and add the registry entry.
Value Name: MaxUserPort
Value Type: DWORD
Value data: 1024 +
Valid Range: 5000-65534 (decimal)
4 Exit the Windows Registry Editor.
5 Restart the Windows Server computer.
Increasing the Size of the TCB Hash Table
The transmission control block (TCB) holds information about TCP connections that are made between View
Connection Server clients and their desktop sources. To support a large View desktop deployment, you can
increase the size of the TCB hash table.
The TCB is a memory-resident data structure that contains socket numbers, the location of incoming and
outgoing data buffers, bytes received or unacknowledged, and other information.
To retrieve this information quickly, Windows Server stores TCB data structures in a hash table.
By default, Windows Server configures the number of hash table rows based on the number of CPUs in the
Windows Server computer.
You use two different formulas to calculate the TCB hash table size on View Connection Server instances and
security servers.
Calculate the Size of the TCB Hash Table for View Connection Server
To support a large number of View desktops, you can optimize the size of the TCB hash table on each View
Connection Server instance. Calculate the size in rows.
Procedure
Use the following formula.
u
Number of hash table rows on each View Connection Server instance = ( (5 x clients) / servers )
+ desktops + 20
