Learning about repositories
Data repositories are implemented as VSAM data sets.
A master repository catalog keeps track of the VSAM data sets that are used for a subsystem. When you specify global parameters during initial setup, allocation and use of repository data sets are automated.
Repository data is organized into one of the following data groups:
- ANALYSIS—user settings and database state information
- ENVIRON—user settings and configuration data
- STATS—statistical and historical data
Tip: For faster searching, add an asterisk to the end of your partial query. Example: cert*
