With one exception, the following procedures control system access by placing
limitations on users when they attempt to log on to the system. The
exception automatically logs an inactive session off the system.
Controlling Access With Logon UDCs |
 |
Logon UDCs (a type of User Defined Command) can be used to confine the system
access capabilities of individual users within rigidly defined limits.
A logon UDC is one that executes whenever a user logs on. Each level in the
system can have a logon UDC that executes at that level. System Managers
create and control system logon UDCs, Account Managers create and control
account logon UDCs, and users create and control their own logon UDCs. System
and Account Managers also can control user UDCs.
You might use the system level logon UDC to prevent users from accessing
MPE/iX commands. For example, a logon UDC with NOBREAK runs an application program
then automatically logs users off the system as soon as they exit the program.
In this case, users have access only to the application program, but not to the
MPE/iX command interpreter or other system facilities.
Creating a UDC |
|
To create a UDC, type the commands you wish to use in a text file, then
catalog the file with the :SETCATALOG command. If a UDC is to be a logon UDC, declare it as such when you create it. Set the UDC level
(system, account, or user) at the time you catalog it. The MPE/iX Commands Reference Manual (32033-90006) describes in detail how to create and catalog UDCs.
