Functional Overview

The following database characteristics are defined with ADADEF:


Database Components

Each database component (Associator, Data Storage, and Work) must be formatted by the ADAFRM utility before it is defined with ADADEF. The ADADEF utility may also be used to define a new Work data set for an existing database.

Systems using the Recovery Aid feature require a recovery log (RLOG) data set, which must first be formatted with the ADAFRM utility, and then defined using the ADARAI utility.
