Need the ability to restrict user(defined in my application) from having multiple concurrent logons on different terminals. The User should have only one logon on any workstation and any point of time.Is there any way to implement this using CICS functionality.

one way that came in my mind is to store application defined user in file while logging in , and delete that while logging off. How ever if user does not logoff properly then that ID will be stuck untill file is manually edited.Please suggest how to tackle this.

Thanks in advance.

brijesh_mca1,

Here is a probable solution.

File content is a very poor resource to depend on. If the user does not log off cleanly, they can not use the system again until the file is cleaned up. Maybe a day, maybe a week, maybe never. Find some other resource to check, preferably one that automatically disappears when the user logs off. Normally outside of CICS this is done via an ENQ but I don't know how ENQs and logins relate in CICS. Certainly the ENQ (among other things) is what is used in TSO to prevent multiple logins. Or there may be a way to simply see who else is logged in and deny the login programatically.

You could issue a INQUIRE TERMINAL command. loop thru looking for the USERID
and the Transaction id. If you do not found a match then continue with you program otherwise display a message and terminate.

I seem to recall that you can setup RACF that it only allows a single sign on. Can not verify it now.
