How do I delete the inactive residential subscriber instances?

Purpose

It is recommended that you periodically remove the inactive subscriber instance records from the NFM-P main database. A subscriber instance becomes inactive when the associated subscriber is deleted from an NE. The inactive instances accumulate rapidly, for example, in a Wi-Fi offload deployment.

Perform this procedure to configure and execute a script that removes the inactive subscriber instance records from the main database.

Note: Before you perform the procedure, it is recommended that you disable the GUI client timeout so that you can use the client GUI to monitor the script execution. Otherwise, if the execution takes longer then the GUI client timeout, you can monitor the script execution using the NFM-P user activity log.

Steps
Disable GUI client timeout
 
1 

Choose Administration→Security→NFM-P User Security from the NFM-P main menu. The NFM-P User Security — Security Management (Edit) form opens.

2 

Set the Client Timeout (minutes) parameter to 0, which specifies no timeout.

3 

Save your changes and close the form.

Configure a script bundle
 
4 

Choose Tools→Scripts from the NFM-P main menu. The Scripts form opens.

5 

Choose Script Bundle (Scripting) from the drop-down menu and click Search. A list of script bundles is displayed.

6 

If a subscriber instance deletion script bundle is listed, go to Step 12.

7 

Click Browse Examples. The Browse Examples of Scripts form opens.

8 

Navigate to the required bundle example. The path is Script Bundle Examples→Miscellaneous→Remove Inactive Residential Subscriber Instances Bundle.

9 

Select the bundle example and click Create Bundle. The Script Bundle (Create) form opens.

10 

Configure the Name parameter.

11 

Save your changes and close the forms.

Execute the script bundle
 
12 

Select the script bundle in the Scripts form and click Properties. The Script Bundle (Edit) form opens.

13 

Select Remove Residential Subscriber CTL and click Execute Script. The Execute Script form opens.

14 

Configure the parameter on the form to specify the number of days of inactivity that qualify a subscriber instance for deletion.

Note: If the NFM-P forwards statistics or billing information to NSP Analytics, ensure that the parameter value is greater than the billing period in days to ensure that no inactive subscriber instances are deleted before the billing occurs.

15 

Click Execute. The script execution begins.

While the script runs, a new item with an hourglass symbol is displayed in the navigation panel on the left side of the form. When the script execution is complete, the symbol changes to a green check mark.

16 

Close all forms.

17 

If required, restore the GUI client timeout to its original value.
