Data set size assist facility
Use the DS Size Assist options to view, update, and delete each individual data set record in the database.
A data set record exists in the database for each data set that passed SPACAQTY filter list processing at data set allocation.
Reporting on these views requires that the DS Size Assist feature is active. The feature is responsible for dynamic allocation of the DB to the MainView SRM address space. The Data Set Size Assist feature is part of MainView SRM Allocation.
The following table summarizes each data set size assist option and its corresponding SETSRM keywords and action line commands.
