Today I got questions about the z/VSE sign-on panel and concurrent userids.
- 1st question: Why "LOGON HERE" PF key (PF12) is displayed on the IUI (Interactive User Interface) entry panel ?
Answer: If a user wants to sign on to a z/VSE system but is already signed on at another terminal, the message
USER ID ’xxxxx ’IS ALREADY IN USE AT TERMINAL ’nnnn’
is displayed and the entry panel provides PF12 with the function LOGON HERE.
LOGON HERE specifies that if this user ID is already logged on, it should be disconnected from its current terminal and reconnected at the terminal where this logon is requested.
If you want to disable this function, change the statement SIGNONH in skeleton IESELOGO to N (No).
SIGNONH DC C’N’SIGNON-HERE CAPABILITY
The IESELOGO skeleton is shipped in the VSE/ICCF library 59. More details on the IUI entry panel are described in the z/VSE Administration book.
You can download that book from the z/VSE Knowledge Center - here.
- 2nd question: Can I sign on to different CICS subsystems in the same z/VSE system with the same user id ?
Answer: Yes, the sign on exit IESEXIT (skeleton SKEXIT1) allows a user to sign on to different CICS subsystems in the same z/VSE system with the same user ID and password and receive different initial selection or application panels. More details are described in the z/VSE Administration book.
- 3rd question: Is it possible to sign on to one CICS subsystem with the same userid from different terminals ?
I know, years ago there was a discussion on VSE-L about this subject and about a patch.
Does anyone use "concurrent sessions with the same userid" ? What are your experiences ?
