Step 5: Defining a default TAS initialization parameter list

An initialization parameter list is used when the TAS initializes.

This parameter list must reside in your hilevel.sysid.UBBPARM data set, and it must be named BBVTAS00. If you do not define a parameter list member, the TAS initializes by using default parameters (see Understanding TAS initialization parameters for information about the default values).

You can create other parameter lists containing different initialization parameters if a single default list does not suit your site requirements or if you want to configure AutoLogon sessions; see Defining other LAS and TAS initialization parameter lists for more information.

To define a default TAS initialization parameter list

  1. Create UBBPARM member BBVTAS00 in hilevel.sysid.UBBPARM.


    • You must name your default member BBVTAS00. If defining additional parameter list members, you must name them BBVTASxx, where xx is a unique value. Do not use a different naming convention for your parameter list members.

    • The UBBPARM data set must have the following attributes:

      • DSORG=PO

      • LRECL=80

      • RECFM=F or RECFM=FB (FBS is not supported)

  2. Copy hilevel.BBPARM member BBVTAS00 to the new member.
  3. Follow the instructions at the top of the UBBPARM(BBVTAS00) member to customize the BBVTAS00 initialization parameter list.
