Defining historical data support
To define historical data support for your product
- Allocate and format a historical database of VSAM data sets for the PAS supporting your products (see Understanding the historical database).
Define the data sets in the historical database to the PAS started task procedure (see Customizing after installation) or use the DSLIST view (see Allocating historical data sets to the historical database).
BMC recommends that you define data sets to the historical data set by using the DSLIST view because this method provides more flexibility with initial recording options and deallocation.
After the historical database is created and at least one file is allocated to hold historical data, you manage the historical database and control access to historical data by using the DSLIST view. DSLIST allows you to perform tasks such as
determining which historical data sets are available for recording data
changing the status of historical data sets
controlling read and write access to the historical data sets
You also might want to archive and restore historical data sets with the standard utility your site uses.
