Before creating historical data sets

Each PAS requires its own set of historical data sets if any product in the PAS intends to keep historical data.

If you are running MainView for z/OS, and you want to implement long-term history recording, you need to define a second set of historical data sets. For long-term history files, the low-level qualifier begins with HST1DSnn (rather than HISTDSnn). After the long-term files are defined, see MainView for z/OS customization for information about activating long-term data collection.

If you are running version 3.0.00 (or later) of MainView for z/OS or version 5.8.00 (or later) of CMF MONITOR , and you want to implement short-term history recording, you need to define another set of historical data sets. For short-term history files, the low-level qualifier begins with HST2DSnn (rather than HISTDSnn). After the short-term files are defined, see MainView for z/OS customization for information about activating short-term data collection.

If you do not want to use historical data for products that run in the z/OS PAS, delete the HISTDSnn and HST1DSnn DD statements from the PAS started task procedure that is described in Creating the CAS startup procedure.

If you are running version 11.1.00 (or later) of MainView for DB2, you need to define a set of historical data sets to contain one-minute statistics records. The low-level qualifier begins with HST1DSnn (rather than HISTDSnn).
