Description
VTLAPSY is a ten-character resettable User 0 parameter that, if set to a non-blank value, indicates the name of an APSY subsystem that can be used to provide full-screen login support for IODEV=7 terminals (3270-type). For TN3270 connections, the same functionality is provided via the NEWSESCMD parameter on the JANUS DEFINE command.
When an IODEV=7 terminal connects to Model 204, one of four connection states is possible:
- Terminal connection contains no user data (the typical case).
- Terminal connection is the result of a VTAM transfer of control from a different Model 204 online. A zap for SirMods Version 7.7 allows VTAM transfer of control even when RACF is used.
- Terminal connection request passed user data, and the X'0040' bit of TERMOPT is not set. In this case the user data will be processed as a command at connect time.
- Terminal connection contains user data, and
TERMOPT=X'0040'. In this case the user data will be prefixed with the string "LOGON " and the result will be processed as a command.
When an IODEV=7 terminal connects with no user data and VTLAPSY is
set to a non-blank value (for example, YOURVT75), the following processing is performed:
- The user is temporarily "logged in" with a USERID =
YOURVT75(the subsystem name), ACCOUNT = NO ACCOUNT and with X'00' privileges. - The $Sir_Login function is enabled.
YOURVT75is entered automatically as a command.- The YOURTV75 subsystem is expected to format a full screen which prompts the user for a valid userid and password and then uses $Sir_Login to log the user in.
- If command level is reached without a successful $Sir_Login call, or if the VTLAPSY subsystem attempts an APSY transfer without a successful $Sir_Login call, a MSIR.0722 non-terminal message is issued and the terminal is disconnected.
- If command level is reached after a successful $Sir_Login, then any AUTOSYS subsystem for the thread will be processed.
- Any environmental error in $Sir_Login will result in request
cancellation.
Note: A VTLAPSY subsystem must be configured to not log a user in or out (Nsettings forLog user into M204and forLog user out of M204in the APSY SUBSYSMGMT Operational Parameters screen).
Sample APSY
A sample apsy that can be used with the VTLAPSY parameter is provided by Sirius Software. The code is in the SIRIUS file, beginning with ULSPF Version 7.7. Programs are VTLN.LOGIN and VTLN.ERROR, and the comments in VTLN.LOGIN explain how to customize the programs for the local environment.
