Setting virtual terminal options


This section describes the steps for setting virtual terminal options for a specific IMS.

  1. 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.

    Note

    If any users are not required to sign on, do not specify signon required. All users will attempt signon bypass if you do not specify signon required. If signon bypass is not successful, the user will still be required to sign on.

    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.

    Warning

    Using a multiple LTERM per node TSS table for signon or signon bypass requires a special TSS translation, which precludes the use of pattern masking in these tables.

    Tip

    Use this option only if your NLTERM table has at least one node with more than one LTERM. This does not pertain to using a node as the LTERM and signing on multiple times.

    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.

  2. Edit the fields as necessary.
  3. Save the changes to the virtual terminal options.
