Help on processes not associated with a TTY
Hi all ^_^
Okay, here's the problem:

There's an IBM RS6000 server running AIX 4.3 with Informix database in my workplace. During peak hours, it has about 350 users doing mostly database operations. It has been set up that those users can only log-in the system at one terminal at a time. Due to many reasons (improper disconnection from the system, disrupted connection, etc), some users' processes are hung in the system, eating up system resources, even though they got disconnected. Those processes are the ones without a TTY when examining the output of the command "ps aux"

Thus, our system operators receive a lot of user requests to kill their processes. A shell script is used to kill all processes without a tty(terminal name) belonging to a specified user. Apparantly,
our operators are sick of getting calls to kill those dead processes.

I want to know if there's a way to prevent this problem from happening at all (or decrease the frequency of this problem)

NAME

       mongo - the Mongo command-line tool

SYNOPSIS

       mongo [OPTIONS] [DB_ADDRESS] [FILE+]

DESCRIPTION

       mongo  is  a JavaScript shell (with GNU readline capabilities).	It supports interactive and non-interactive use.  When used interactively,
       JavaScript can be used to query the database or perform any other function normally available with SpiderMonkey.  Database output  is  dis-
       played in JSON format.

       If JavaScript files are specified on the command line, the shell will run non-interactively, running each one in sequence and then exiting.

EXAMPLES

       mongo  start the shell, connecting to the server at localhost:27017 and using the test database

       mongo foo
	      start the shell using the foo database at localhost:27017

       mongo 192.169.0.5/foo
	      start the shell using the foo database at 192.169.0.5:27017

       mongo 192.169.0.5:9999/foo
	      start the shell using the foo database at 192.169.0.5:9999

       mongo script1.js script2.js script3.js
	      run three scripts and exit

OPTIONS

       --shell
	      run the shell after executing files

       --help show usage information

       --host HOST
	      server to connect to (default HOST=localhost)

       --port PORT
	      port to connect to (default PORT=27017)

       --nodb do not connect to mongod

       --eval SCRIPT
	      evaluate JavaScript

       -u USERNAME
	      specify user to log in as

       -pPASSWORD
	      specify password of user (notice there is no space)
