Data set management

When you select Data Set Management from the EZSRM menu, you advance to the Data Set Management menu options.

The Data Set Management options provide a set of real-time and historical data set level views to simplify daily DASD housekeeping tasks. These reports and utilities enable you to perform the following tasks:

  • Evaluate performance and data management statistics from the data set level and up to more general levels (very broad or very narrow, whichever you need)

  • Inspect data sets from the catalog and VTOC viewpoint

  • Locate problem data sets and take action if necessary; for example, you could identify the following:

    • Oldest data sets not accessed

      You can use this data to determine whether you need to retain these data sets. Taking this action can prevent problems in pools and on the system.

    • Largest data sets

      You can use this report to determine the best location for data sets.

  • Locate and correct volumes that contain excessive VSAM data sets with splits in the control interval (CI) and control area (CA)

    For more information, view the Quick Course MainView SRM Reporting- Find VSAM Data Sets with CA Splits .

    You must have a BMC Support ID to view the Quick Course.

  • See size analysis and aging of data sets on ML0, ML1, and ML2

    This view shows the flow of data sets through the various resources, from creation to deletion or expiration. This data can be seen by management class, group or pool, HLQ, application, and other resources.

To access data set information or to choose and perform actions against data sets, you first select an option from one of the submenus. From the resulting submenu options, you can choose the criteria for selecting data sets, such as those of a certain age on a particular volume. You can then drill down to a specific data set and use the EZDS EZCmd menu options to get detailed information about that data set.
