Allocating historical data sets to the historical database
After you have created and formatted the VSAM files that comprise the historical database as described in Managing historical data sets, you are ready to allocate the data sets that you want the historical recorder to write to.
MainView provides the following methods for allocating historical data sets to a PAS:
Dynamic allocation through the DSLIST view
The PAS does not need to be recycled if you add historical data sets by using this method.
Allocation at PAS initialization by including DD statements in the PAS started task procedure for each data set
The PAS must be recycled if you add historical data sets by using this method.
If you prefer, you can use a combination of both methods (hardcoding DD statements in the PAS procedure and interactive allocation with the DSLIST view) to allocate as many historical data sets as you need during your user session.
