CAS library member

BBILIB member @@YZZ022 contains statements for customizing or creating a CAS startup procedure in your system started task procedure library (see Creating the CAS startup procedure). The following table lists the CAS started task procedure statements.

Statement

Description

//procname PROC parms

This statement identifies the started task procedure and its parameters.

For information about the parameters, see the following topics:

Note

You can override these parameters with the START command for the CAS, as described in Starting a CAS.

//CAS EXEC

References a program named BBM9ZA00 that processes EXEC parameters and performs basic initialization tasks.

You can use the PARM parameter to override the default parameter values that are specified with the PROC statement.

TIME=1440 defines unlimited processing time for the CAS.

REGION=4096K specifies the size of the private region that is required by the CAS. Do not define a region smaller than 4096 K.

//STEPLIB DD

Defines the BBLINK load library, which contains load modules for all MainView products.

The CAS requires some of these load modules; each product address space requires other modules.

Note

Delete this statement if BBLINK is added to your system link list.

//BBSECURE DD

Defines the data set that contains security resource definitions.

These definitions are used by the CAS and PAS to determine whether security checking should occur for access to systems, products, views, and actions. The same data set name must be defined for the CAS started task procedure BBSECURE statement and the PAS started task procedure BBSECURE statement.

Note

Defining a BBSECURE data set is only part of setting up security with your external security manager (ESM). For more information, see Managing security for MainView products.

//BBACTDEF DD

Defines the data set that contains distributed action and view tables.

These tables help the CAS determine valid view names and actions. The BBACTDEF data set also contains default security parameter files and resource definition files. The CAS accesses this data set in response to window commands and actions that are associated with Plex Manager views.

//BBVDEF DD

Defines the library that contains distributed views.

//BBIPARM DD

Defines and concatenates MainView product parameter libraries.

If you establish cross-system communication or create target or SSI contexts, all definitions are stored in the hlq.UBBPARM data set, which is created by the Installation System during the configuration process.

hlq.BBPARM contains distributed parameters.
