Database Requirements
Database creation involves the following 4-step process:
Step 1 - Create a Master Definition File: This step involves creating the 
master definition file that defines the fields in the master database file. 
Step 2 - Build a Master Database File: This step involves entering data into 
the master database fields that were just defined in the master definition file in 
Step 1. 
Step 3 - Create an Application Definition File: In this step, a definition file is 
created for the master database. This file defines the formats by which data from 
the master file is to be converted to meet the needs of the VFNA application.
Step 4 - Process and Install the Application Database: In this step, the 
Process and Install Application Databases option on the APM Database 
Administration menu creates the file that will be used by the VFNA application. 
When the Process option is activated, data is drawn from the master database 
and converted to the formats specified in the application definition file. The 
Install option is then activated to enable the VFNA application to copy its 
database.

Looking at your Default Database
A template of the default form or scheme is automatically installed from the 
installation disk. Therefore, there is no need to build (define) a master database 
field for this application.

Building a Master Database
After an application is installed and configured, the master database must be built. 
To build a master database, do the following.
1. Go to the System Administration screen (Figure 3-11).
Figure 3-11   System Administration 
2. In that screen, select D for Database Administration, then press Enter.
The Database Administration screen displays (Figure 3-12).
Figure 3-12   Database Administration 
3. Press B for Build Master Database, then press Enter. 
The Master File Selection screen displays (Figure 3-13).

4. At the Master File Selection screen, select vfnadb_m, then press Enter.
The vfnadb_m Database Entry screen displays (Figure 3-14).

5. To create a new database entry, edit the master file by entering the Name, 
Extension, Tenant, Forward Extension, and Delay in Seconds.
Note:Press A to add another entry or N to go to the next entry.
6. Press Q for Quit, then press Enter.
7. Type Y for Ye s to save changes.

Sample Database 
EntryThis is a sample setting of a database entry:
Name = Test
Extension = 1000
Te n a n t  =  1
Forward Extension = 2000
Delay in Seconds = 10 seconds 
This sample setting means that if the phone extension is 1000, it will ring for 10 
seconds. If it doesn’t answer by then, VFNA will forward the call to extension 
station 2000. Variable Forward No Answer, in plain English, means that the VFNA 
database directs where and when to forward the call. 
Specifying the Application Database Field
The VFNA application database field has already been copied from the installation 
disk. Therefore, skip this procedure.
Processing the Application Database
After building the master database, it must be processed before the application is 
able to use the data from the database. 
To process the application database, do the following:
1. Go to the System Administration screen.
The System Administration screen displays (Figure 3-15).
Figure 3-15   System Administration 
2. In that screen, select D for Database Administration, then press Enter.
The Database Administration screen displays (Figure 3-16).

4. Select vfnadb_m, then press Enter.
The message below the command line should then say: Database process 
operation complete.
5. Press Escape to exit.
The Database Administration screen displays again (Figure 3-18).

base, then press Enter.
The Install Application Database screen displays (Figure 3-19).

Ongoing Configuration Management Issues
To add a new phone number after installation, do the following:
1. Build the master database. 
2. Add a new name. 
3. Perform the Processing the Application Database procedure detailed above.
4. Then perform the Installing the Application Database procedure detailed 
above.
Application Start-
UpThe standard application start-up is as follows:
1. The server comes up. 
2. The APM platform starts up.
3. The VFNA application initializes. 
Note:The assumption here is that the initialization batch option is set to Y. If it is 
set to N, the application must be started manually.
To manually start the application, do the following:
Note:The assumption here is that the initialization batch option is set  to N.
1. From the System Administration screen of the APM, select the Operations 
menu.
2. Verify that OAI is initialized by observing the top line of the display. The 
application manager should have an “*” at the end of the name. If there is no 
“*”, select Initialize OAI, then press Enter. 
3. Select non-crt application control.
4. Select I for Initialize, then press Enter. 
5. Select VFNA by moving the cursor and pressing Enter to highlight VFNA.
6. Press Escape.
7. Press Y at the prompt: Initialize selected apps? (Y,N).

8. Press Enter. 
User TasksThere is no user interface to this application. VFNA becomes active when the APM 
initializes the VFNA application. It must be maintained by the APM administrator. 
The administrator’s duties would be to add, modify, and delete records to the 
VFNA APM database. 
Note:See the Data Requirements section for the fields required in the database.
