About this task

An example is a filter that selects all UNIX servers in the Australian data center.

With filters, you can:

• Create multiple versions of a filter and then select the version you want to use.
• Use one filter on multiple certification schedules.
• View the number of records that match your filter as you create the conditions.

Note:

Be sure to create certification filters before creating certification schedules.

Procedure

1. Navigate to All > Data Certification > Certification Filters.
2. Click New.
3. Fill in the form (see table).
4. Click Submit.
   This action saves the filter as version 1.

5. To create another filter version, modify the filter conditions and click Update.
   The system saves the new filter and increments the version number.

   Figure 2. Certification filter V2

   

   By default, the Certification Filters list shows only the current version of each filter. To see all filter versions, click All in the breadcrumbs.

6. To make an inactive filter the current version, open the inactive filter and click Revert.

   This action creates a new, active version of the filter and makes all previous versions inactive.

7. To delete a single filter version, open that version record and click Delete.
8. To delete inactive versions of a filter, click Delete inactive versions under Related Links in that filter record.
   You cannot delete a filter that is used in a schedule definition. The system displays a warning and the filter is not deleted.

   Table 1. Creating certification filters

   Field	Description
   Name	[Required] Filter name.
   Description	[Optional] Brief description of the filter.
   Number	[Read-only] Automatically assigned filter identification number.
   Table	Table containing the records to be filtered. Use of the Database View [sys_db_view] table is limited by version.
   Active	Control to make the filter available for use from the Filter field on the Certification Schedule form.
   Version	Current version of this filter. Any significant changes to the filter make the current version inactive. The system copies the updated filter, marks it as active, and increments the version number. The system saves all versions of the filter and makes them available to users. More than one version of a filter can be marked active.
   Filter condition	Field, operator, and value to create the condition. The available options depend on the table selected. You can view the number of records that match the filter by clicking the refresh icon. Figure 5. Refresh Conditions If the filter does not match any records, the system marks the certification instance as Closed Complete, with the Percent complete value set to 100%.
