3.5 Generate a Database Unit


A database unit is one physical database within the database
complex.  In updating and reporting for this physical
database, the shared libraries, defined at the database
complex-level, are used, as well as a unique set of libraries
associated to the database unit.

This phase of the installation ensures that the proper
catalog definitions are made, the database unit libraries
and database files are allocated, the JCL/CLISTs are
generated, the installation PROCLIB is updated, and PARMS
have been defined and generated.

The steps in defining, generating, and allocating a database
unit are:

    1 - Define Catalog Indexes for Prefix and Tapeprefix
    2 - Build Database Unit Libraries
    3 - Generate JCL/CLIST Procedures
    4 - Move CA MICS PROCs to Installation PROCLIB
    5 - Generation of Parameter (PARMS) Defined Options
    6 - Generate and Allocate the Database
    7 - Finalize a Database Unit
