Hi All,
Is there a way to find, who is purging our TSO session for eg: one Id has been used by group of people so each one of them will login to the TSO session from different machines.

You should be able to find out by looking at the console log
or ask the operator to look it up for You

network issues? maybe?

Hello,

one Id has been used by group of people so each one of them will login to the TSO session from different machines.
This practice can cause sessions to disappear. Often when "user2" tries to log in, the system gives the opportunity for the "new" login to pre-empt the existing session "user1".

Hi Dick,
for eg: If i am using C machine so the next one can use A or B or J Machine then the session will not disappear but my problem is that someone from A or B or J is puging mine i.e) C machine.

Please clarify this. How do these "machines" exist? I would expect multiple peole to sign on to one machine. How does it happen that the next one to login goes to a different machine?

Hi,
For one userid Eg: abcdef
we can have 6 to 7 machines rite
since i am logging in to only one machine other machines will be free hence others login through other machines thats how other machines exist.so multiple people are signing on to multiple machine not to one
machine.
hope this will be clear

Hi,

I think you want to say, there is one RACF ID say XX1234A, there are, say, five PCs (Personal Computers) with 3270 simulators installed on them; different users are trying to "log-in" on Mainframes using the same RACF ID XX1234A on these five PCs (machines). In order to get a successful login on a different PC your session was cancelled by some one & you want to know who is that some one?

Hi,

Yes, that would tell you the last command "used" on your ID.

If these machines are desktop machines and you are logging on to the same mainframe service (i.e. tso, cics) you will have the problem i mentioned earlier. Multiple people cannot use the same mainframe id at the same time on the same service from different terminals.

Is there a reason that each person cannot have their own userid?

Hi,
For eg: XX1234A this is my id
i login to tso session by
TSOA1
XX1234A
PASSWORD

likewise others can login
TSOB1
XX1234A
PASSWORD

TSOC1
XX1234A
PASSWORD
so someone who logs in B1 or C1 is puging my machine

Is there a reason that each person cannot have their own userid?
yes thats right

Hi,
U mean to say like u have different TSO sessions say TSO1, TSO2, & TSO3 and u r using TSO1 with ur Racf XX1234A and
the other 2 using TSO2, and TSO3 with the same Racf XX1234A but different PCs,
so one of the other two are purging TSO1 connection with user ID XX1234A,
so as i know in any case the purging Owner ID will be XX1234A,
So i suggest if U know who are those two using Racf XX1234A ask them not to purge Ur TSO1 session(as per i know no other method).

He asked a question, it was not an opinion. To use a single RACF ID to login on mainframes by multiple users is not "permitted" across the shops, at my shop it's a severe security violation.

this thread has been going on long enough without getting anywhere icon_evil.gif
Ask the operation support to look at the console log to identify the cause

This is probably because vtam is only permitting one login per id.

Most security administration does not support the same id logged on multiple times.

I'd suggest you set up some number of "test user ids". The permissions for these test ids can be modified as needed.

If these are "real" users, they should have their own id. They should not use yours.

it' s not a security issue... it' s an issue related to system setup ...
dataset allocation, grs definitions...

for reasons to discourage such approach

if the O/P, instead of whining, had provided a bit more info we could have solved the issue by now icon_lol.gif

anyway unless they played some tricks, multiple logon are not allowed on the same system
Code:
IKJ56425I LOGON rejected, UserId IBMUSER already logged on to system XXXX
IKJ56400A ENTER LOGON OR LOGOFF-
