Defining BBVTASxx members for EXCP AutoLogon sessions

Any member is pointed to at TAS initialization by specifying the SUF= keyword with the START command.

The LOGON command contained within a BBVTASxx member is used to specify the following subparameters for an AutoLogon session:

• UCB(ucb), where ucb is a valid EXCP terminal unit name
• DATA(userID/password)
  • userID is a valid user ID that is defined to the external security manager (ESM) and can have at least read access to the FACILITY(BOOLEBBV) so that userID does not require a clear text password. For more information about defining security for MainView Alternate Access, see Security-implementation-for-MainView-Alternate-Access.
  • password is a valid password for userID, if userID requires a password.  Passphrases and IBM Multi-Factor Authentication for z/OS (IBM MFA) are not supported.
• OPT(x;x;x), where x;x;x is a valid option string

To define BBVTAS xx members for EXCP AutoLogon sessions

1. Read the information in Defining-other-LAS-and-TAS-initialization-parameter-lists and follow the instructions in Step-5-Defining-a-default-TAS-initialization-parameter-list to create a new BBVTASxx member in UBBPARM.

2. Use the following syntax rules to define the LOGON command and subparameters in a BBVTASxx member:

   • Each line must contain the LOGON command.
   • A single line cannot exceed 72 bytes.
   • Always begin the LOGON command in column 1.
   • Do not code comments on the same line as a LOGON command.
   • If the LOGON command and subparameter string exceeds 72 bytes, continue on additional lines by defining the LOGON command on each line that contains valid subparameters.
   • A single subparameter must be coded on one line; it cannot be started on one line and continued on another line.

   Note

   See Defining-the-START-command-for-EXCP-AutoLogon-sessions for a description of each keyword and LOGON command subparameter.

3. Use the SUF keyword in the START command to initialize your AutoLogon session; see Controlling-TAS-initialization-parameters-EXCP for a description of this keyword.

Example of defining the LOGON command in a BBVTASxx member

The following example shows how the LOGON command can be defined to a BBVTASxx member for an EXCP AutoLogon session.

The default values are used in these examples, but your site might have defined other values; see Defining-the-START-command-for-EXCP-AutoLogon-sessions for more information.

You can specify the following commands:

LOGON UCB(J43) DATA(VEA1/VIRGINIA)

LOGON OPT(Z;1;;;;;SCR OVERVIEW;W2.LO;W4.LO;ASU 5;W3.DOWN)

As a result, the OVERVIEW screen is displayed with windows 2 and 4 locked, the remaining windows in automatic screen update (ASU) mode set at 5 seconds, and the data in window 3 scrolled down, assuming that user VEA1 has previously created a MainView for z/OS screen named OVERVIEW.

Multiple ; (semicolons) are defined consecutively in the OPT subparameter value to adjust for the amount of time that a particular system might typically require to process the Connecting... message that is displayed when accessing the MainView window interface.

To invoke this AutoLogon session, you would issue the following START command:

S BBVTAS.VEA1,SUF=xx

In the preceding command,xx is the two-character suffix that is assigned to the BBVTASxx member containing the LOGON command.
