Question 1

What is the primary function of TN Bridge?

Accepted Answer

TN Bridge enables applications to interact with 3270 terminal screens. It provides APIs for .NET, ActiveX, and Delphi-Native applications, facilitating access to mainframe applications. This allows modern applications to integrate with legacy systems without requiring extensive mainframe code changes.

Question 2

What programming languages and application types are supported by TN Bridge?

Accepted Answer

TN Bridge supports .NET, ActiveX, and Delphi-Native applications. These APIs allow developers to create applications that can send commands to and receive data from 3270 terminal screens. This enables the modernization of applications that interact with mainframe systems.

Question 3

How does TN Bridge facilitate the integration of modern applications with legacy mainframe systems?

Accepted Answer

TN Bridge facilitates the integration of modern applications with legacy mainframe systems. It provides a bridge between the two, allowing applications to access and manipulate data on 3270 terminal screens. This integration helps extend the life of legacy systems while enabling new functionality.

Question 4

What mainframe platforms are supported by TN Bridge?

Accepted Answer

TN Bridge is designed to work with z/OS, z/VM, and zVSE/VSEn platforms. This compatibility ensures that applications can interact with mainframe systems running on these operating systems. This allows for a wide range of deployment options.

Question 5

What are the most common commands and their syntax in TN Bridge?

Accepted Answer

Common commands include `Connect`, `SendKeys`, `ReceiveData`, `Disconnect`, and `Wait`. The syntax varies depending on the API used, but generally involves calling methods with parameters specifying the terminal session and data to be sent or received. For example, in .NET, you might use `tnBridge.SendKeys("session1", "LOGIN")`.

Question 6

What types of APIs does TN Bridge expose, and what are some example method names?

Accepted Answer

TN Bridge exposes APIs for .NET, ActiveX, and Delphi-Native applications. These APIs provide methods for connecting to terminal sessions, sending keystrokes, receiving data, and disconnecting. The specific API endpoints and method names depend on the chosen development environment.

Question 7

What protocols and components are involved in the communication process?

Accepted Answer

TN Bridge uses TCP/IP for communication. The main components include the TN Bridge Server, client-side libraries (for .NET, ActiveX, Delphi), and the terminal emulation layer. The client libraries communicate with the server, which then interacts with the mainframe.

Question 8

How is TN Bridge configured?

Accepted Answer

Configuration is typically managed through configuration files and API calls. Configuration files store settings such as connection parameters, session definitions, and security settings. The API allows for dynamic configuration changes during runtime.

Question 9

What is the business value of using TN Bridge?

Accepted Answer

TN Bridge allows organizations to extend the life of their mainframe applications by enabling modern applications to interact with them. This reduces the need for costly and time-consuming mainframe code changes, preserving existing investments. It also enables new functionality.

Question 10

How does TN Bridge improve developer productivity?

Accepted Answer

By providing APIs for various development environments, TN Bridge allows developers to build new applications or modernize existing ones that interact with mainframe systems. This improves developer productivity and reduces the learning curve for mainframe integration.

Question 11

How does TN Bridge mitigate the risks associated with mainframe integration?

Accepted Answer

TN Bridge helps organizations avoid the risks associated with rewriting or replacing mainframe applications. It provides a stable and reliable solution for integrating with legacy systems, reducing the risk of downtime and data loss. This also reduces costs.

Question 12

How does TN Bridge help organizations leverage their existing mainframe investments?

Accepted Answer

TN Bridge enables organizations to leverage their existing mainframe investments by providing a bridge to modern applications. This allows them to extract more value from their mainframe systems without requiring significant changes to the core mainframe applications.

Question 13

What authentication methods are supported by TN Bridge?

Accepted Answer

TN Bridge supports various authentication methods, including user ID and password, and integration with external authentication systems. These methods ensure that only authorized users can access the mainframe resources through the TN Bridge.

Question 14

How is access control managed in TN Bridge?

Accepted Answer

TN Bridge supports access control through configuration settings, allowing administrators to define which users or groups can access specific terminal sessions or perform certain actions. This ensures that users only have access to the resources they need.

Question 15

What audit and logging capabilities are available in TN Bridge?

Accepted Answer

TN Bridge provides logging capabilities to track user activity and system events. These logs can be used for auditing and troubleshooting. The logs record events such as user logins, session connections, and data transfers.

Question 16

What encryption methods are used in TN Bridge?

Accepted Answer

TN Bridge uses encryption to protect sensitive data during transmission. This ensures that data exchanged between the client applications and the mainframe is secure. Encryption is applied to the communication channel.

Question 17

What administrative interfaces are available for TN Bridge?

Accepted Answer

Administrative interfaces include configuration files and potentially a command-line interface (CLI) for managing the TN Bridge Server. These interfaces allow administrators to configure settings, monitor performance, and manage user access.

Question 18

How is user management handled in TN Bridge?

Accepted Answer

User management is typically handled through configuration files or integration with existing user directories. Administrators can define user access rights and permissions within the TN Bridge configuration. This ensures proper access control.

Question 19

What are the main configuration parameters?

Accepted Answer

Key configuration parameters include connection settings for the mainframe, session definitions, security settings, and logging levels. These parameters are typically stored in configuration files and can be modified to adjust the behavior of TN Bridge.

Question 20

What monitoring and logging capabilities exist?

Accepted Answer

TN Bridge provides monitoring and logging capabilities to track system performance and troubleshoot issues. These capabilities include logging of events, performance metrics, and error messages. This helps in maintaining system stability.
