I was writing a pgm to write a file. Suddenly mainframe hanged and not able to login again. While trying to login, it says user id is already logged in.

Please help me to solve this problem.

1) Ask operations or one of your peers to cancel your user id
2) Sit back and do nothing until your session times out
3) Try to logon with the RECONNECT option

Hi,

Pardon my ignorance - but what does the above statistics show? Does above say that a user A500066 logged-in on 29 AUG 2003 & didn't log out till 24 OCT 2003? If yes, what kind of system management is that? icon_confused.gif

Anuj, I think that prino is trying to say that if the background task is in a loop it will be deemed as active and so the TSO session would not time out.

Actually, this particular client didn't have a automatic TSO logoff time and virtually nobody in IT logged off, we just locked out session at the multi-session manager screen.

In this case I had to log off because my password had expired icon_cry.gif

4) If you are still connected when it hangs, if PA1 and ATTN do not work press SYSREQ (see your emulator keyboard map) and when the screen goes blank, enter LOGOFF. Only works on some systems.
5)Use FTP to submit a job that has nothing but a dummy step and a // C U=userid command. Only works if you have authority to issue operator commands
Code:
//... job ...
// C U=your-userid
//WHATEVER EXEC PGM=IEFBR14 or anything else even if it doesn't exist

6) Some sites have a web interface or a session manager interface to something that cancels your id. I wrote a small web page(CGI in Rexx) to let people submit the job shown in (5) but ours is a mostly unsecured development/test system so everyone has pretty much authority to do anything if they know how to do it. Check with your site help desk.
