TPX - Session Management


From a TPX menu users are able to activate applications that reside on other systems. 

Is there a way to prevent users from activating sessions dynamically?   



Release : 5.4

Component : CA-TPX for OS/390



TPX supports dynamic sessions (access to VTAM applications that are accessible to the VTAM Host that TPX is running on,
 and applications that are not defined in the running ACT). When using this feature only Unique Virtual Terminals are used. 
The TPX administrator can limit who can do dynamic sessions through the Command Authorization Classes.

If there is connectivity to the application, regardless of whether it is defined in TPX, it can be accessed.

To prevent the ability to /a to an application from TPX,  review how your command authorization classes are setup and 
put an 'N' by Activate Sessions under Dynamic Sessions.
