Configure an Anti-Affinity Rule for an Application Pool
When you congure an anti-anity rule for an application pool, View Connection Server aempts to launch
the application only on RDS hosts that have sucient resources to run the application. This feature can be
useful for controlling applications that consume large amounts of CPU or memory resources.
An anti-anity rule consists of an application matching paern and a maximum count. For example, the
application matching paern might be autocad.exe and the maximum count might be 2.
View Connection Server sends the anti-anity rule to Horizon Agent on an RDS host. If any applications
running on the RDS host have process names that match the application matching paern, Horizon Agent
counts the current number of instances of those applications and compares the number to the maximum
count. If the maximum count is exceeded, View Connection Server skips that RDS host when it selects an
RDS host to run new sessions of the application.
Prerequisites
n
Create the application pool. See "Creating Application Pools" section in the Seing Up Desktop and
Application Pools in View document.
n
Become familiar with the constraints of the anti-anity feature. See “Anti-Anity Feature Constraints,”
on page 200.
Procedure
1 In View Administrator, select Catalog > Application Pools.
2 Select the pool to modify and click Edit.
3 In the   text box, type a comma-separated list of paerns to match against the
process names of other applications running on RDS hosts.
The paern string can include the asterisk (*) and question mark (?) wildcard characters. An asterisk
matches zero or more characters and a question mark matches any single character.
For example, *pad.exe,*notepad.??? matches wordpad.exe, notepad.exe, and notepad.bat, but it does
not match wordpad.bat or notepad.script.
N View counts multiple paerns that match for an application in a single session as a single match.
4 In the  Count text box, type the maximum number of other applications that can be
running on the RDS host before the RDS host is rejected for new application sessions.
The maximum count can be an integer from 1 to 20.
