Purging obsolete programs

During a long period of data collection, CICS® IA can collect data about multiple versions of a program, even though only one program version is allowed to run in a region at a time. This behavior might increase the database storage overhead. Purge old versions of programs to free storage in your database.

Procedure

  1. In any editor or view, for example in the Programs view, right-click the program that you want to purge and click Purge.
    Note: One of the Collection IDs must be set as the current one before purging.
  2. Choose whether to purge the program in one specific region or in all regions.
  3. Follow the wizard to set up and run the purging job.
    • If you selected Specific Region,
      1. On the first page of the wizard, select one region for which you want to purge the program and click Next.
      2. On the second page of the wizard, select the tables that are to be purged and click Next. By default, all tables are selected.
      3. On the last page of the wizard, the rows that are to be purged are displayed. Click Finish to start purging. The last page is informational only. You cannot remove rows.
    • If you selected All Regions,
      1. On the first page of the wizard, select the tables that are to be purged and click Next. By default, all tables are selected.
      2. On the last page of the wizard, the rows that are to be purged are displayed. Click Finish to start purging. The last page is informational only. You cannot remove rows.
