Setting virtual terminal options
This section describes the steps for setting virtual terminal options for a specific IMS.
From the Edit IMSID Options panel, type 3 in the selection field and press Enter.The IMSID Options – VT Options panel is displayed.
The following fields are available on this panel:
IMSID
The IMSID of the options module that you selected.
This is not an editable field.
Enable DELTA PLUS VIRTUAL TERMINAL
A / indicates to activate DELTA PLUS VIRTUAL TERMINAL.
Notify MTO of auto logoffs and exits
A / indicates to send a message to the IMS Master Terminal each time DELTA PLUS VIRTUAL TERMINAL automatically logs off an idle virtual terminal or automatically exits a conversation.
Require signon for ALL virtual terminals
A / indicates that a signon is required after a virtual terminal logon.
A signon is required for DELTA PLUS VIRTUAL TERMINAL enhanced conversation and message-handling features to associate conversations and messages with a userid.
Support multiple concurrent LTERMs for virtual terminals
A / enables multiple concurrent LTERM support for virtual terminals.
If you select this option, each virtual terminal can support up to eight LTERM names. The node and LTERMS must be virtual.
When you do not want multiple LTERMs, the argument length in the Translate Subsystem Services (TSS) table for Signon Bypass options 2 and 3 and Signon options 3 and 4 must equal eight; otherwise, the argument length must be greater than eight to permit suffixed node or userid values.
VT system log code
The log code that DELTA PLUS VIRTUAL TERMINAL will use when it writes records to the IMS system log.
Use any hexadecimal number from X'A0' to X'FF', except X'DA'. The default is X'DE'.
DFS3649A /SIGN COMMAND REQUIRED format name
The name of a Message Output Descriptor (MOD) that displays each time logon occurs at a VTAM terminal where signon is required.
The following MODs may be used in this field:
user-customized MOD
The user's own MOD may be used; however, it should contain a SYSMSG field.
IBM default MOD
The IBM default MOD DFS3649A /SIGN COMMAND REQUIRED is displayed if the field is left blank.
If a signon failure occurs, a message describing the failure will be displayed in the SYSMSG field of the MOD used. To change the message text, use sample JCL in DLPCNTL member DLA#SMSG to assemble and link a replacement module called VTFSMSG0.
DFS3650I SESSION STATUS format name
The name of a Message Output Descriptor (MOD) that displays each time a VTAM terminal which is not required to sign on, logs on to IMS.
If a MOD name has not been supplied and the terminal logs on, the IBM default message DFS3650I SESSION STATUS is displayed.
If a MOD name has been supplied and the terminal logs on, the MOD will be displayed.
- Edit the fields as necessary.
- Save the changes to the virtual terminal options.
