Cisco DNCS System Release 2.8.1 3.8.1 4.3.1 User Guide

The first step in preparing the DNCS for InstaStaging is to add the InstaStaging file to the .profile file. Adding the
InstaStaging flag to this file enables InstaStaging as soon as the DNCS is stopped and restarted. Until the DNCS
is stopped and restarted, InstaStaging remains disabled.

The InstaStaging flag serves two functions:



Whenever a DHCT receives a status of Out-Of-Service, the DNCS automatically changes the status to

Deployed to prepare the DHCT for InstaStaging.



The DNCS sends new staging EMMs to any DHCT with a status of Deployed or In-Service Two-Way the

first time the DHCT makes a two-way connection to the network.

Completing this procedure requires advanced knowledge of UNIX, including experience with UNIX vi editor. UNIX
vi editor is not intuitive. Be aware that the instructions provided here are no substitute for an advanced working
knowledge of vi. For this reason, we recommend that you do not proceed unless you have experience with UNIX
vi editor.

Adding the InstaStaging flag to the .profile file takes about 15 minutes. 

Stopping and restarting the DNCS properly can take from 10 minutes to several hours, depending on the size of
your system, how many sessions are active, and so forth.

To enable InstaStaging, stop and re-start the DNCS. When DNCS processes are stopped, two-way
communication also stops in the DBDS. As a result, you will not be able to offer any PPV, VOD, other on-demand
services, or other third-party applications during this time. In addition, you will be able to offer only limited IPG
functionality, and you will not be able to stage DHCTs or update modulator /demodulator code. 

For this reason, stop and restart the DNCS during a period when system usage is low.

Complete these steps to add the InstaStaging flag to the .profile file.

Important: The UNIX vi editor is case-sensitive. Type each command exactly as shown in these instructions.

1.

Log into an xterm window on the DNCS as the dncs user.

2.

Type cd /export/home/dncs and press Enter. The directory /export/home/dncs becomes the

working directory.

3.

Type cp .profile .profile.old and press Enter. The system makes a backup copy of the file .profile,

and names the backup copy .profile.old.

4.

Use the UNIX editor of your choice to edit the .profile file and add the following two lines:
