UNDERISZSMGR

Description

Specifies what should happen to the physical terminal when a target application is selected from the Menu panel.

This common session parameter is applicable to these control statements: SYSTEM (see SYSTEM statement), PROFILE (see PROFILE statement), USER (see USER statement), TERMINAL (see TERMINAL statement), and APPL (see APPL statement).

Format

UNDERISZSMGR|CLOSEDISC|CLOSELOGOFF

Default: UNDERISZSMGR

Usage

CLOSEDISC causes the physical terminal to be disconnected from IBM Session Manager when a target application is selected from the Menu panel. (See also TYPE.) As a result, any other active sessions remain active and may be re-entered exactly where they were left when the user quits from the selected session. This parameter should therefore be used instead of CLOSELOGOFF in a situation where a user normally has multiple sessions active.

CLOSELOGOFF causes IBM Session Manager to relinquish control of the physical terminal to the target application as soon as the application is selected. (See also TYPE.) The logmode entry name and any data defined using the DATA parameter are passed to the target application. If the target application is not currently accepting logins, the request is rejected and an error message issued.

This parameter would normally be used in conjunction with the LOGAPPL parameter of the VTAM LU statement which defines the terminal to VTAM. In this way, the terminal can be logged back on to IBM Session Manager as soon as the user quits from the application and have the Menu screen displayed again.

For terminals at which a single application only is usually active, this technique may be useful since it cuts out the overhead of IBM Session Manager processing all the data streams passing between the physical terminal and the application. It does however have the disadvantage that no other sessions can be run simultaneously to which the user can transfer control as would normally be the case. No IBM Session Manager messages or broadcasts will be received at the terminal while it is controlled by the target application and no scripts may be run.

Note: If SHAREDISC or SHARESESS are being used to implement the Shared User Facility (see the Installation and Customization manual) then CLOSELOGOFF will behave as CLOSEDISC for the primary user (the first terminal logged on with the userid), but for secondary users CLOSELOGOFF will behave as usual.

For further details on the implications of using the CLOSEDISC and CLOSELOGOFF parameters, see 'Using IBM Session Manager as a front-end' in the Installation and Customization manual.

If UNDERISZSMGR is specified, or allowed to default, the physical terminal remains under the control of IBM Session Manager, and the user can switch between sessions without the need to quit from any session.
