Question 1

What is Virtel Web Modernization?

Accepted Answer

Virtel Web Modernization transforms 3270 applications into web-based interfaces. It emulates a 3270 terminal, capturing host output and converting it to HTML. User input from the web is translated into 3270 keystrokes, which are then sent back to the host application. This process is transparent to the host applications, requiring no modifications.

Question 2

What types of devices and browsers are supported?

Accepted Answer

Virtel supports various web browsers and devices. It allows users to access and interact with legacy applications from any device with a web browser. This includes desktops, laptops, tablets, and smartphones, providing a consistent user experience across different platforms.

Question 3

How does Virtel Web Modernization work?

Accepted Answer

Virtel Web Modernization operates by intercepting 3270 data streams. It emulates a 3270 terminal, receiving data from the host and converting it into HTML. User interactions are converted into 3270 keystrokes and sent back to the host. This process is managed by the Virtel server, which handles the communication and transformation.

Question 4

What are the key benefits of using Virtel Web Modernization?

Accepted Answer

Virtel Web Modernization provides a web-based interface for accessing and interacting with legacy 3270 applications. It eliminates the need for users to install and maintain 3270 terminal emulators. This simplifies access and management, reducing the complexity associated with traditional terminal-based access.

Question 5

What are the most common commands and operations?

Accepted Answer

Common commands include those for session management, screen navigation, and data entry. Session commands include START, STOP, and STATUS. Screen navigation uses commands like PF1, PF2, and cursor positioning. Data entry involves standard keyboard input, emulating 3270 keystrokes.

Question 6

What configuration files or interfaces are used?

Accepted Answer

Configuration is primarily managed through the Virtel configuration files. These files define terminal emulation settings, screen mapping, and security parameters. The Virtel Web Interface (VWI) provides a web-based interface for configuring and managing these settings. Changes to the configuration files require a Virtel server restart to take effect.

Question 7

What types of APIs does Virtel expose?

Accepted Answer

Virtel exposes APIs for integration with other systems. These APIs allow for programmatic access to Virtel's functionalities, such as session initiation, data retrieval, and screen manipulation. The APIs support RESTful web services, enabling integration with various applications and platforms.

Question 8

What are the main system components?

Accepted Answer

The core components include the Virtel Server, the Web Interface (VWI), and the Session Manager. The Virtel Server handles 3270 emulation and communication with the host. The VWI provides the web interface for users. The Session Manager manages user sessions and connections.

Question 9

What protocols does Virtel use for communication?

Accepted Answer

Virtel uses HTTP and HTTPS for communication between the web browser and the Virtel server. The Virtel server communicates with the host applications using TN3270E protocol. These protocols ensure secure and reliable data transfer.

Question 10

How does Virtel Web Modernization provide business value?

Accepted Answer

Virtel Web Modernization extends the life of legacy applications by providing a modern web interface. This allows organizations to avoid costly rewrites. It enables continued use of existing business logic and data, reducing the risk and expense associated with application modernization.

Question 11

How does Virtel improve user productivity?

Accepted Answer

By providing web access, Virtel improves user productivity. Users can access applications from any device with a web browser, increasing flexibility and efficiency. The modern web interface enhances the user experience, making legacy applications easier to use.

Question 12

How does Virtel reduce IT costs?

Accepted Answer

Virtel Web Modernization reduces IT costs by eliminating the need for 3270 terminal emulators. This simplifies IT management and reduces the costs associated with software installation, maintenance, and support. Centralized management through the web interface further streamlines operations.

Question 13

How does Virtel help leverage existing investments?

Accepted Answer

Virtel enables organizations to leverage existing investments in legacy applications. It allows businesses to extend the value of their existing systems without the need for major overhauls. This approach provides a cost-effective way to modernize applications and maintain business continuity.

Question 14

What authentication methods are supported?

Accepted Answer

Virtel supports various authentication methods, including user ID and password, and integration with external authentication systems. It supports LDAP, SAML 2.0, and X.509 certificates. These methods ensure secure access to the modernized applications.

Question 15

What access control model is used?

Accepted Answer

Virtel uses an access control model based on user roles and permissions. Administrators can define roles and assign permissions to control user access to specific functions and data within the modernized applications. This role-based access control (RBAC) ensures that users only have access to the resources they need.

Question 16

What encryption is used and where?

Accepted Answer

Virtel uses HTTPS to encrypt communication between the web browser and the Virtel server. This ensures that all data transmitted is protected. Sensitive data, such as user credentials and session information, is encrypted to prevent unauthorized access.

Question 17

What audit/logging capabilities exist?

Accepted Answer

Virtel provides comprehensive audit and logging capabilities. It logs user activities, including login attempts, session activities, and configuration changes. These logs are essential for security monitoring, troubleshooting, and compliance purposes.

Question 18

What administrative interfaces are available?

Accepted Answer

The primary administrative interface is the Virtel Web Interface (VWI), a web-based console. The VWI allows administrators to configure settings, manage users, monitor sessions, and view logs. It provides a centralized point for managing the Virtel environment.

Question 19

How is user management handled?

Accepted Answer

User management is handled through the VWI. Administrators can create, modify, and delete user accounts. User authentication can be integrated with external directories like LDAP. Role-based access control (RBAC) is used to manage user permissions.

Question 20

What are the main configuration parameters?

Accepted Answer

Key configuration parameters include terminal emulation settings, host connection details, and security configurations. These parameters are set through the VWI and stored in configuration files. Changes require a Virtel server restart to apply.

Question 21

What monitoring/logging capabilities exist?

Accepted Answer

Virtel provides monitoring and logging capabilities through the VWI. Administrators can monitor active sessions, view system logs, and track performance metrics. These features help in troubleshooting and ensuring optimal system performance.
