9.3. Procedure – Creating and editing protocol-level ICA settings


ICA settings determine the parameters of the connection on the protocol level, including timeout value, and so on. Complete the following procedure to create a new ICA settings profile or edit an existing one:

Figure 9.1. ICA Control > Settings — ICA settings

ICA Control > Settings — ICA settings

Modifying the ICA settings is recommended only to advanced users. Do not modify these settings unless you exactly know what you are doing.


  1. Navigate to the Settings tab of the ICA Control menu item and click to create an ICA setting profile. Enter a name for the profile (for example ica_special).

  2. Click to display the parameters of the ICA connection.

  3. Modify the parameters as needed. The following parameters are available:

    • Idle timeout: Connection timeout value in milliseconds. To avoid early timeout, set it to a larger value, for example a week (604800 seconds).


      Determining if a connection is idle is based on the network traffic generated by the connection, not the activity of the user. For example, if an application or the taskbar of a graphical desktop displays the time which is updated every minute, it generates network traffic every minute, negating the effects of timeout values greater than one minute and preventing PSM from closing the connection.

    • Reconnect timeout: How many seconds PSM waits for reconnections when reliable connections are used. Reliable connections use the Common Gateway Protocol (CGP).

    • Server connection attempts: How many times PSM tries to connect to the target server.

    • Reconnection intervals: How many seconds PSM waits between two connection attempts on the server side.

    • Enable pre channel check: Select this option to evaluate the connection and channel policies before establishing the server-side connection. That way if the connection is not permitted at all, PSM does not establish the server-side connection.


    Reliability settings only apply if you have enabled Reliable connection in ICA Control > Connections.
