Can same/multiple users invoke the same CICS transaction from same terminal?

I'd say - Yes, but not at the same time.

I kind of disagree...

You cannot have two user logged-on on the same terminal at the same time

the construct same-terminal multiple-users

is flawed/murky to start with, each different user will have to logon/do some work/logoff

furthermore in some organization there is a strict connection between the user and the <devices> he/she is allowed to use to logon to the system

at the end everything depends on the security setup

Enrico, I don't see the (kind of) disagreement - I did say "not at the same time".

Well, that was a surprising end to the topic.

Does it really imply that you thought it was not possible to have the same user using the same transaction from the same terminal (presumably only on the same day, rather than for ever, or until CICS falls over, whichever is sooner)?

Amit_Singh47, I think you need to start over again with your CICS training. CICS terminals must have unique identifiers, so you cannot have multiple terminals with the same terminal id in a region. Hence only one user at a time can be using a given terminal. Therefore, as stated your question makes no sense -- UNLESS you mean that a user signs onto a region, gets assigned terminal id WXYZ, keys in transactions, then signs off followed by another user signing onto the region and being assigned terminal id WXYZ and starts keying in transactions. In this case, the transactions could be the same, the terminal id would be the same, but the timestamps of the data in SMF would show what happened.

You need to clearly tell us what prompted the question -- are you looking at SMF data (in which case there could be multiple transactions from the same terminal id with different user ids, scattered throughout the recording period?

Good day to all!
A user could use a transaction simulator at his terminal for testing purpose. He could generate multiple transactions with the same trans ID and terminal ID but CICS would assign different task ID to each transaction.

Yes, but those transactions would not run simultaneously - they would be serialised..... just as though s/he entered them manually (but quicker)
