Understanding Data Purges

You can use purge programs to remove data from files when the data becomes obsolete or you need more disk space. You can use data selection to create a configured purge. For example, you could specify a range of fiscal years so that the system would purge only records that fall within that date range instead of all dates.

To purge data, you must:

  1. Determine the data that you want to purge.

  2. Run the purge program.

  3. Run the file reorganization program to rebuild file structure.

Note: You must know the proper procedures and consequences of purging data to avoid serious damage to the system and data.
