For each security server, the result is 7,510, as shown in Table 5-13.
Table 5-13. Example of Calculating the Size of the TCB Hash Table on Each Security Server
Configuration Parameter Sample Values
Projected number of concurrent client desktop connections 3,000
Number of security servers 2
( (5 x clients) / security servers ) + 10 = number of TCB hash
table rows on each security server
(5x3,000) / 2 + 10 = 7,510
What to do next
Use the “Worksheets for Calculating Ephemeral Ports and TCB Hash Table Size,” on page 67 to fill in values
for your deployment.
Increase the Size of the TCB Hash Table on a Windows Server Computer
Edit the Windows registry to increase the size of the TCB hash table on a Windows Server computer on which
View Connection Server runs.
Active Directory group policies can override registry entries. When possible, use a group policy to set the size
of the TCB hash table on View Connection Server.
Procedure
1 On the Windows Server computer, start the Windows Registry Editor
a Select Start > Command Prompt.
b At the command prompt, type regedit.
2 In the registry, locate the subkey and click Parameters.
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters
3 Click Edit > New and add the following registry entry.
Value Name: MaxHashTableSize
Value Type: DWORD
Value data: calculated hash table size
Valid Range: 64-65536 (decimal)
4 Exit the Windows Registry Editor.
5 Restart the Windows Server computer.
