System Components

Cerify accesses digital media from local storage, such as a local hard drive or DVD, as well as network storage, such as a Windows ﬁle server or FTP server.

A Cerify system can be set up in three basic ways:

The ﬁrst consists of a single self-contained unit which runs all the management and testing processes

of the system.

The second consists of a networked cluster of two or more units, which enables simultaneous

processing of a greater number of ﬁles. The networked cluster contains a single Supervisor and one

or more Media Test Units.

The third consists of a cluster of three or more units with high availability (HA) support. Cerify

Enterprise Cluster with high availability (also referred to as an HA cluster) is a Cerify cluster enabled

with support in the case of a Supervisor system failure.

Cerify Automated Video Content Veriﬁcation System User Manual 5

Getting Started Product Description

License Dongle

The license dongle must be plugged into the USB port on your computer to run the application. In a clustered system, Media Test Units acquire their licenses from the Supervisor.

In the case of an HA cluster, two identical license dongles are supplied. The two dongles need to be inserted in the USB ports of the primary and secondary supervisors. Media Test Units will acquire licenses from the active primary Supervisor.

License dongle

It is possible to navigate the user interface and see previous results when no dongle is installed, but it is not possible to carry out new checks of digital media ﬁles. The license dongle controls:

The types of codecs and ﬁle formats that can be checked

The number of channels that can be used

Serve or not, etc.)

NOTE. If you unplug a dongle and plug in another dongle, or if the connected dongle is upgraded with a new v2c ﬁle, a restart of Cerify is necessary for the license dongle to work correctly.

When you install a new version of the Cerify software for a high availability (HA) cluster, both of the dongles connected to the primary and secondary Supervisors must be upgraded.

Getting Started Product Description

Networking

In a clustered conﬁguration, network interface on all of the units, including the Supervisor, secondary Supervisor (HA cluster only) and Media Test Units, should be connected to the local area network. This connection is used to access media ﬁles, to service Web clients, and to carry cluster control trafﬁc.

Software Components

Software components include:

A Web-based user interface, which allows users to create and control Jobs, and to view or report the results of these Jobs. This interface is accessed over the network by using a Web browser. All you need to know is the IP address of your unit.

Media test service, which performs media ﬁle veriﬁcationaccordingtotheruleschosenbytheuser.

A database, which provides robust storage of the system entities, including users, Jobs, and Job results.

An XML-based control and reporting API known as CeriTalk. CeriTalk allows interaction with Cerify from within other applications, making it possible to integrate Cerify with other content management, broadcast automation, and workﬂow systems.

A Web application server that provides access to the Web interface and runs the core services for the application.

A license server, which controls the types of ﬁles t hat can be veriﬁed.

The system tray icon and menu, which provides access to the Cerify Web-based user interface and allows the application to be started and stopped. The system tray is not available when Cerify is installed as a Windows service.

Cerify as a Standalone System

A standalone system is a single machine that combines the functions of a Supervisor unit and a Media Test Unit. The process that carries out the media ﬁle testing is known as the Media Test Client (MTC).

Cerify Enterprise Cluster

The Supervisor unit controls the cluster system. It hosts the database and the Web server, allowing multiple users to set up and view Jobs.

Cerify High Availability Enterprise Cluster

The Cerify high availability enterprise cluster (also referred to as an HA cluster) is a Cerify cluster enabled with support in the case of a Supervisor system failure. In an HA cluster, one of the member units of the cluster is conﬁgured as a backup to the Primary Supervisor and is called the Secondary Supervisor.

If Cerify on the Primary Supervisor goes down for any reason (for example, due to a machine crash), the Secondary Supervisor automatically takes over and manages the cluster. All other units (MTUs) now form aclusterwi the Secondary Supervisor and will be ready to take over when the current Supervisor goes down.

The Second and the MTUs in the cluster while performing the job of a Secondary Supervisor.

In an HA cl interface cards on the system. One will be used for the cluster function and the other for communication (Ceritalk/Web). Also, it is mandatory to use static IP addresses for all the units forming the HA cluster.

In an HA cluster, identical dongles must be connected to the Primary Supervisor and Secondary Supervisor. When starting an HA cluster, the cluster units should be started in the following order:

1. The Primary Supervisor should be started ﬁrst with one of the two HA dongles installed. At the time the Primary Supervisor is started, the system with the Secondary Supervisor installed should be up and have the matching HA dongle installed. Otherwise, the Primary Supervisor will not start.

2. The Secondary Supervisor should be started next.

3. The Media Test Units should be started one by one after both the Primary Supervisor and Secondary

Supervisor are started.

All of the PCs in the cluster should be able to route to each other. The Supervisor unit and the Secondary Supervisor unit (in the case of an HA cluster) each need to be given a network name that is recognized and resolved by all of the units in the cluster.

You should know the fully qualiﬁed name of the Supervisor unit and the Secondary Supervisor unit and provide these when the installer of the other units in the cluster asks for the names of the Supervisor and Secondary Supervisor units.

In the case of a normal cluster (non-HA cluster), if the Supervisor or Media Test Units have more than one network interfaces, it is better to bridge all the network interfaces together. For instructions on conﬁguring the network bridge, refer to Conﬁguring a Network Bridge

Synchronization between all the units in cluster must be maintained. For example, use an NTP server to synchronize the units in a cluster.

Clustering Scenarios Which may not Work

Clusters may not work in the following scenarios:

If the Supervisor, the Secondary Supervisor (in the case of an HA cluster), and the Media Test Unit are in different subnets wherein the switch blocks the multicast or UDP trafﬁc.

If any of Supervisor, Secondary Supervisor, or Media Test Unit systems has Windows ﬁrewall running, the Firewall may need some additional conﬁgurations for the cluster to work. Contact your Tektronix representative for more informationonhowtosetupthisconﬁguration.

If a Media Test Unit or Secondary Supervisor cannot resolve Supervisor host name.

In the case of an HA cluster, if the Supervisor can not resolve the host name of the Secondary

Supervisor and vice versa.

If the Supervisor does not have a host name or if the Supervisor has a host name with Japanese or Chinese characters.

If a network has another system with the same host name as the Supervisor (or Secondary Supervisor) system.

If the host name of the Supervisor (or Secondary Supervisor) changes after cluster installation.

If the http port on the Supervisor is conﬁgured to a different port number after cluster installation. In this case, the property cerify.supervisor.httpport in the cerifysystem.properties on the Media Test Units must be changed to the new port number.

If the http port on the Supervisor is conﬁgured differently than that of the Secondary Supervisor.

If the IP addresses of any units in the cluster change after the installation. In this case, the property cerify.jboss.bindaddress must to be changed to the current IP address.

In the case of a normal (non-HA) cluster, if the Supervisor has multiple network i nterfaces connected to the same network and if DNS/WINS are not conﬁgured properly, troubleshoot this problem by doing either of the following:

By adding an entry containing the Supervisor host name and the IP address used by Cerify on Supervisor in "hosts" ﬁle, which can be found in

C:\WINDOWS\system32\drivers\etc in all

the Media Test Units.

By bridging all the network interfaces together.

Clusters might not work correctly if there is momentary network outage in which case the clusters have to be restarted.

Getting Started System Installation

System Installation

This section provides details of hardware, software and user prerequisites for the system and instructions on performing the software installation.

Prerequisites

Hardware Prerequisites

Cerify is designed to be run on a variety of PC hardware. Consequently, the choice of hardware is determined by performance and throughput requirements for your installation.

This section recommends hardware conﬁguration for some situations in which Cerify is typically used.

Cerify can be installed as either of the following two conﬁgurations on a given computer:

Single channel. A single channel installation is one that is licensed to test a single media ﬁle at a time. Such installations are normally performed on a PC or a laptop computer and are suitable for situations where a low throughput is sufﬁcient and performance is not critical.

Multichannel. A typical multichannel installation of Cerify tests 4-8 media ﬁles at a time on a single unit. Due to the high throughput and performance requirements that are expected from such installations, it is recommended that server class hardware and operating systems be used in such cases.

In addition to the throughput required, the hardware requirements also depend heavily on the mode of operation that will be used. Cerify can operate in two modes:

Streaming mode

In this mode, media ﬁles are read directly from the media server hosting the ﬁle and are not copied to the local hard disk of the Cerify system. This is the default mode of operation and is also the preferred one.

Copying mode

Media ﬁles are copied to the local hard disk of the Cerify system before processing can begin. By default, Cerify will not copy ﬁles to the local hard disk, but it is possible to force Cerify to operate in this mode.

The mode of operation that applies to your Cerify installation depends on the ﬁle formats you would like to test and other work ﬂow and connectivity related constraints that might apply to your situation. See the

Modes of Operation

The functional differences between these two modes of operation impact primarily on the disk space availability and disk conﬁguration requireme of disk space and high levels of concurrent read/write performance from the hard drives in order for best overall performance while the streaming mode can derive comparable overall performance with a lesser amount of disk space and lower read/write efﬁciency. Consequently, when possible, the streaming mode should be used in preference to copying mode.

The general guidelines that should be followed when selecting hardware are:

Processor: 3 GHz

Cerify is capable of using as many processor cores as available for improved processing performance. While the minimum required conﬁguration is 2 cores per channel, for optimum performance, it is recommended to allocate between 4 and 6 processor cores per Cerify channel. It is also recommended that for best performance, you choose as much on-chip memory cache as possible.

NOTE. Cerif Intel based server platform.

Memory:

It is recommended to use a minimum of 4 GB of RAM per channel and an additional 4 GB for the operati memorythereforeis: 4x4GB(perchannel)+4GB=20GB.WhentheexpectedloadinCerifyis likely to be largely composed of huge media ﬁles, more memory per channel may be necessary.

Hard disk drive: 100 GB x 3

For systems that are expected to support high levels of throughput, it is recommended that you have 500 GB of space on this logical drive.

The amount of additional storage you need depends on the mode of operation that applies to your installation, the average size of the ﬁles you will be processing and the number of channels you will be running.

Streaming mode

Due to the minimal hard disk utilization when operating in the streaming mode, it is sufﬁcient to provide a single dedicated hard disk of 100 GB in size as temporary storage for Cerify.

Copying mode

The minimum hard disk space provided must be greater than the average ﬁle size being processed multiplied by the number of channels. It is recommended that the temporary storage be RAID-ed for better performance.

For help choosing the optimal number of hard disks for your installation and the best RAID levels to use, see Conﬁguring Your Cerify Installation for Best Performance

Network interface: 1 Gbit/s

You might use multiple network interfaces to improve available network bandwidth.

Installation Considerations

Before installing Cerify, you should be aware of the following information:

It is re sole running application. Cerify makes intensive use of both CPU and memory and will considerably degrade the performance of other running applications. Similarly, running other applications or services simultaneously will degrade the performance of Cerify and increase the time taken to process amediaﬁle.

Cerify relies on third-party software applications that are packaged and installed with it: JBoss and MySQL. If these applications are already used on the PC, you should remove them before attempting to install the Cerify.

The Cerify license server relies on Sentinel HASP (formerly Aladdin HASP SRM) drivers, which are installed and conﬁgured along with it. It is recommended that other applications that rely on HASP

censes not be used with Cerify on the same machine.

Cerify uses a number of network services that are local to the host PC. These services can sometimes

e blocked by personal ﬁrewall software, in which case an error message will be displayed when Cerify

b starts. For example, on Cerify start up, a check is made to verify that communication with HASP can be established. If the Cerify application is unable to communicate with HASP, an error message,

Unable to connect to HASP License Manager (port 1947). Please check if the HASP License Manager service is running and is not blocked by a ﬁrewall is displayed and Cerify is stopped.

In such situations, conﬁgure the ﬁrewall to allow the service on the appropriate port, or alternatively disable the ﬁrewall entirely.

An installation log is written to the "%userproﬁle%\Cerify\CerifyInstallationLogs_<Timestamp>" folder. This log gives details of selections you made during the install and any errors encountered in case of failure to install.

If you would like multiple users to be able to run the Cerify application on the PC, make sure you select a location that has read and write permissions for those users as the temporary video folder. A directory located within a user's private directory is not s uitable in this case.
