Load modules, libraries, and sample members

The following sections list of load modules, libraries, and sample members that are shipped with MainView Alternative Access:

Load modules

The following load modules are installed for MainView Alternative Access.

These load modules must reside in an APF-authorized library that is concatenated to the STEPLIB DD statements in both the LAS and TAS PROCs.

Load module

Description

BBVCLOAD

Used for common services that support both LAS and TAS functions.

BBVJLOAD

Used for TSO services that are required for TAS functions.

BBVLLOAD

Used by the LAS for user logons to VTAM sessions.

BBVSLOAD

Used for local SVC screening services that support TAS functions.

BBVTLOAD

Used for TAS initializations.

Libraries

The following libraries are shipped with MainView Alternate Access:

  • BBCLIB

  • BBPARM

  • BBPLIB

  • BBSAMP

  • BBTLIB

The BBCLIB, BBPLIB, and BBTLIB libraries contain modules specifically for customizing MainView Alternative Access.

The BBPARM and BBSAMP libraries contain sample members that are used for customization. These members are never the target of SMP operations. To apply maintenance against BBPARM and BBSAMP members, you must first apply all PTFs and then perform the customization steps that create or change the affected members.

BBPARM data set members

The following table lists customizable members that are shipped in BBPARM and are copied to a user parameter library (default is hilevel.sysid.UBBPARM) for modifications during customization.

The user parameter library must be concatenated by a BBVPARM DD statement in both the LAS and TAS procs.

BBPARM member name

Description

BBVLAS00

Customizable member that is used to define the session environment at startup for each user that logs on to a VTAM session. This member is required only for VTAM session access, not EXCP sessions. The BBVLAS00 member is the default member. Other parameter list members can use the naming convention of BBVLASxx.

BBVTAS00

Customizable member that is used to define the session environment at startup for each session. This member is required for both VTAM and EXCP sessions. The BBVTAS00 member is the default member. Other parameter list members can use the naming convention of BBVTASxx. In fact, an AutoLogon session that is started by an automation product or during the IPL procedure requires its own parameter list member, which contains a LOGON command.

BBSAMP data set members

The following table lists sample members that are shipped in BBSAMP and copied for modification to a user sample library (default is hilevel.UBBSAMP), unless otherwise specified.

The user sample library must be concatenated by the SYSPROC DD statement in the TAS proc.

BBSAMP member name

Description

BBVINIT

REXX EXEC that allocates the ISPF environment for each TAS session

During customization, this sample member is copied for modification to a site-specified data set (default is hilevel.UBBSAMP) that must be concatenated by the SYSPROC DD statement in the TAS proc.

BBVINITC

CLIST that creates the ISPF environment for a TAS session if your site does not run REXX

Note: BMC Software strongly recommends that you use the BBVINIT REXX EXEC if your site does run REXX. Follow the instructions at the top of this sample CLIST to customize it to your site requirements.

BBVLAS

Sample started task procedure for initializing the LAS

The LAS is used only for user logons to VTAM sessions and not for EXCP sessions. During customization, this sample member is copied for modification to a site-specified data set (default is hilevel.UBBSAMP), and, after it is modified, it is copied or moved to a site-wide procedure library.

BBVLIT

Sample logon interpret table entry to see whether you can add to your logon interpret table, after which you can recompile the table to shorten the VTAM user logon command

The BBVLIT member is used optionally for VTAM access customization, if required and appropriate to your site. During customization, this sample member is copied for modification to a site-specified data set (default is hilevel.UBBSAMP).

BBVLVER

Verification job to check that all CSECTS for all PRD load modules are present

It creates output showing the results of the verification procedures as well as the PTF maintenance level for each CSECT.

BBVTAS

Sample started task procedure for initializing each TAS

The TAS proc is used for all VTAM and EXCP session initializations. During customization, this sample member is copied for modification to a site-specified data set (default is hilevel.UBBSAMP), and, after it is modified, it is copied or moved to a site-wide procedure library.

BBVTASA

Default VTAM application major node definition (containing a minor node root name with 10 minor nodes) that identifies PRD to VTAM

The application major node definition is required only for VTAM session access.

During customization, this sample member is copied for modification to either a site-specified data set (default is hilevel.UBBSAMP) or a data set that is concatenated by the VTAMLST DD statement. If copied to a user library for modification, the BBVTASA member must be moved to a VTAMLST DD data set or the user library must be concatenated to VTAMLST DD.

BBVUSST

Sample USS table entry that you can add to your USS table, after which you can recompile the table to shorten the VTAM user logon command

The BBVUSST member is used optionally for VTAM access customization, if required and appropriate to your site. During customization, this sample member is copied for modification to a site-specified data set (default is hilevel.UBBSAMP).
