Modify an Existing External Filter

Use the External Filter/Class Manager to modify an External Filter.

To modify an existing External Filter

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 contains the External Filter you want to modify.

   The External Filter you want to modify is listed in the Available Filters pane.

4. Select the External Filter you want to modify in the Available Filter pane.

   Note: Modify is enabled only when an External Filter is selected in the Available Filter pane.

5. Click Modify.

   Note: External Filters must have a Source Object to be valid. You cannot create an External Filter without specifying a Source Object if you are using the External Filters/Classes Manager. However, External Filters are stored in a PDS and it is possible for users to write a filter directly to its member. Such filters might not contain a Source Object. If you are using the External Filters/Classes Manager to modify an External Filter that does not contain a Source Object then an error message is displayed when you click Modify and the modify process stops. The syntax of the External Filter must be corrected manually in the PDS member. For more information, see the CA Vantage SRM Reference Guide.

   The External Filters/Classes Manager Modify dialog is displayed. The following is an example of the External Filters/Classes Manager Modify dialog showing the NEWNAME External Filter:

   

6. You can use this dialog to change the Filter Name and Description. If you only want to change the filter expression, skip to step 6.

   Note: If you change the Filter Name, a new External Filter is created with the new name using the existing External Filter as a template.

   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.
   • You cannot change the Source Object using this dialog.
7. Click OK.

   The External Filters/Classes Manager Modify dialog closes and the External Filters/Class dialog is displayed.

8. Modify the filter expression if needed. After you have modified the filter expression, you can optionally click Verify Filter on Host on the External Filters/Class dialog toolbar to test if the filter expression is valid.

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

9. Click Apply and Exit.

   The External Filter/Class dialog closes and a confirmation dialog is displayed.

10. Click OK.

    The confirmation dialog closes and the External Filters/Classes Manager dialog is displayed.
