Editing an option set

You can edit the option sets by executing the product's CLIST or the LGCISPF CLIST. All methods invoke the same LGC dialog.

Before you begin

The DBC started task must be running and the LGC agents must be active.

To edit an option set

  1. On the Options Set panel, type E next to the option set that you want to edit and press Enter.

  2. Expand each section and review or change the values.

    Success

    Tip

    For repeatable sections, you can:

    • Enter I next to the section to insert a new section that uses all default values.
    • Enter R next to a section to duplicate the section with its current values. You can then edit the repeated section to create a unique section.

    Repeatable sections include a number in parentheses behind the section name.

    Warning

    Important

    While editing the option set, you might receive validation error messages if fields contain invalid entries. Validation errors change the filter setting to Filter: Invalid, and only fields that have validation errors are displayed. When you correct an validation error, the associated field is no longer displayed on the panel. When you have corrected all the validation errors, the filter reverts to its previous setting (for example, Filter: Required or Filter: Off).

    You can manually change the filters if you want to see all options. For more information about filtering, see Filtering-option-sets.

  3. Save your option set by pressing F3.

Example of working with default values for option sets

This example demonstrates how to create default values for a section in an option set. Doing so allows you to define your own default values so that whenever you insert new instances of a section, you will have fewer values to update.

The values that you specify for section defaults are used whenever you insert a new instance. If you change a value in a section default, any value in an instance that matched that value prior to the change is eligible for being updated to the new value. This process allows you to change the values in multiple instances of a section at once, without opening and closing each instance.

  1. Access the LGC panel for editing the option set (as described in Accessing-the-online-interface).

    The following figure shows an example of a panel for a new DOMPLEX option set used by the System and SQL Performance products.  Each product lists different options.

    Success

    Tip

    The number in parentheses behind the section name indicates the number of instances that exist for a section. Any section that has an instance count of 0 or more is eligible for using section default values. (In the example panel, the DOMPLEX Parameters section does not contain any instances.)

  2. To update section default values, type E next to the relevant section.

    The LGC interface displays a panel that allows you to define the default values pertinent to that section.

    For example, typing E next to DB2 Monitor List displays the panel shown in the following figure.

  3. Make the changes to the option set.

    For example, assume that all of the Class fields were changed to N and the previous value of Y matched the existing instances of the defined Db2 subsystems.

  4. Press F3 to save the changes and display the panel shown in the following figure.

  5. Take one of the following actions:
    • To change the value from Y to N for all instances, type / next to Enter '/' to select all rows or select individual rows in the list field.
    • To change the value from Y to N for only select instances, type / on the action lines next to those specific entries.

  6. Press F3 to save your changes.
