Create a New External Filter

Use the External Filter/Classes Manager to add a new external filter.

Note: You can also use the object Filter option to save an object filter as an External Filter. For more information see the section Defining a Filter.

To create a new external filter using the External Filter/Classes Manager

1. Log in to and then select the Host in the Host List that you want to create the External Filter for.

   You are connected to the Host and that Host is highlighted in the Host List.

2. Select the z/OS menu option External Filter/Classes.

   The External Filters/Classes Manager dialog is displayed.

3. Click the object in the Available Objects pane that you want to create the new External Filter for. The Available Filters pane in the External Filters/Classes Manager displays all the External Filters that exist for the object or advises that no External Filters exist. This gives you the opportunity to see if an External Filter that meets your needs already exists.

   Note: The New icon is enabled only when an object is selected in the Available Objects pane.

4. Click New ().

   The External Filter/Class - New Name dialog is displayed, as shown in the following example:

   

5. Enter the Filter Name and the Description.

   Observe the following:

   • The Filter Name can be a maximum of eight characters.
   • The Filter Name must be unique.
   • The Description can be a maximum of 28 characters.
   • The Source Object field cannot be changed in this dialog. To change the Source Object you must click Cancel and then select another object in the Available Objects pane.
   • A valid external filter must have a Source Object.
6. Click OK.

   The External Filter/Class dialog is displayed. The External Filter/Class dialog shows the new external filter name in the title bar. The following is an example of the External Filter/Class dialog where we are creating a new external filter with the name NEWNAME for the source object POOLS:

   

7. Specify the filter expression. After you have created the filter expression, you can optionally click Verify Filter on Host on the External Filter/Class dialog toolbar to test if the filter expression is valid.

   Note: For more information about filter expressions, see the section Defining a Filter.

   The following is an example of the External Filter/ClassManager dialog with a filter expression of % Alloc greater than or equal to 80:

   

8. Click Apply and Exit.

   After the filter is saved, the External Filter/Class dialog closes and a confirmation dialog is displayed.

9. Click OK.

   The confirmation dialog closes and the External Filters/Classes Manager dialog displays with the new external filter listed. The following is an example of our NEWNAME external filter now listed in the External Filters/Classes Manager dialog for the Storage Group's Space and Other Attributes (POOLs) object:
