Name: IMS Extended Terminal Option Support
Availability: InStock

Question 1

What is the primary function of IMS Extended Terminal Option?

Accepted Answer

IMS Extended Terminal Option (ETO) provides a front-end for managing IMS terminals. It allows administrators to define, configure, and manage terminal definitions within an IMS environment. This includes setting up terminal characteristics, security profiles, and operational parameters.

Question 2

What types of terminals does ETO support?

Accepted Answer

ETO supports various terminal types, including 3270 display terminals and logical terminals. It enables the definition of terminal characteristics, such as screen size, communication protocols, and device-specific attributes. This allows IMS applications to interact with a wide range of terminal devices.

Question 3

What configuration tasks can be performed using ETO?

Accepted Answer

Administrators use ETO to define terminal characteristics, security profiles, and operational parameters. This includes defining terminal names, user IDs, passwords, and access control lists. ETO also allows for the configuration of session limits, transaction routing, and other operational settings.

Question 4

How does ETO simplify terminal management?

Accepted Answer

ETO simplifies terminal management by providing a centralized interface for defining and managing terminals. It reduces the complexity of managing a large number of terminals and provides a consistent way to configure and control terminal access. This improves operational efficiency and reduces the risk of configuration errors.

Question 5

What are the main components of the ETO architecture?

Accepted Answer

The primary components include the ETO Manager, Terminal Definition Database, and the IMS Control Region. The ETO Manager handles terminal sign-on and sign-off, and manages terminal sessions. The Terminal Definition Database stores terminal definitions. The IMS Control Region provides the runtime environment for IMS transactions.

Question 6

How do the ETO components communicate with each other?

Accepted Answer

The ETO Manager communicates with the IMS Control Region using internal IMS interfaces. The Terminal Definition Database is accessed by the ETO Manager and the IMS Control Region to retrieve terminal definitions. Communication protocols include SNA and TCP/IP, depending on the terminal connection type.

Question 7

What commands are used to manage terminals in ETO?

Accepted Answer

ETO utilizes the IMS command structure for operations. Common commands include /OPNDST (open destination), /CLSDST (close destination), /START and /STOP commands for terminals, and /DISPLAY commands for status information. These commands are entered through the IMS console or a 3270 terminal.

Question 8

How is ETO configured?

Accepted Answer

Configuration is primarily managed through the IMS system definition process and the Terminal Definition Database. The IMS system definition defines the overall IMS environment, while the database stores specific terminal configurations. These configurations are accessed and utilized by the ETO Manager.

Question 9

What are the business benefits of using ETO?

Accepted Answer

ETO streamlines terminal management, reducing administrative overhead. It provides a centralized, consistent approach to terminal configuration and control. This leads to improved operational efficiency and reduced risk of configuration errors. The ability to manage a large number of terminals effectively is a key benefit.

Question 10

How does ETO improve operational stability and reduce risk?

Accepted Answer

By centralizing terminal definitions, ETO reduces the potential for configuration errors. It provides a consistent security model across all terminals, improving overall security posture. The ability to quickly respond to terminal-related issues minimizes downtime and service disruptions.

Question 11

How does ETO contribute to cost savings and resource optimization?

Accepted Answer

ETO allows for efficient resource utilization by optimizing terminal connections and session management. This can lead to cost savings by reducing the need for additional hardware and network resources. The centralized management also simplifies capacity planning and resource allocation.

Question 12

What authentication methods are supported by ETO?

Accepted Answer

ETO supports user authentication through RACF or other security managers integrated with IMS. Access control is enforced using security profiles defined in the Terminal Definition Database and the IMS security environment. This ensures that only authorized users can access specific terminals and resources.

Question 13

What access control model is used in ETO?

Accepted Answer

ETO supports role-based access control (RBAC) through the integration with the IMS security subsystem. Users are assigned roles, and these roles determine their access rights to terminals and IMS resources. This simplifies security administration and ensures consistent access control.

Question 14

What encryption methods are used in ETO?

Accepted Answer

Data encryption is typically handled by the underlying communication protocols, such as SNA or TCP/IP, and the security manager. ETO itself does not provide built-in encryption, but it relies on the security features of the network and security infrastructure. This ensures secure communication between terminals and IMS.

Question 15

What audit and logging capabilities are available in ETO?

Accepted Answer

ETO integrates with IMS logging and auditing facilities. All terminal sign-on and sign-off events, as well as any security violations, are logged. These logs can be used for security audits and to track user activity. This provides a comprehensive audit trail for security compliance.

Question 16

What administrative interfaces are available for ETO?

Accepted Answer

Administrative interfaces include the IMS console, 3270 terminals, and potentially, custom-built interfaces using IMS APIs. The IMS console provides a command-line interface for managing terminals. 3270 terminals are used for interactive terminal management. Custom interfaces can be developed for automation.

Question 17

How is user management handled in ETO?

Accepted Answer

User management is handled through the integration with the IMS security subsystem and external security managers like RACF. User IDs and passwords are managed within these systems. ETO uses these credentials for terminal sign-on and access control. This ensures centralized user management.

Question 18

What are the main configuration parameters in ETO?

Accepted Answer

Key configuration parameters include terminal names, user IDs, passwords, security profiles, and session limits. These parameters are defined in the Terminal Definition Database and the IMS system definition. Proper configuration is essential for secure and efficient terminal operations.

Question 19

What monitoring and logging capabilities are available in ETO?

Accepted Answer

ETO provides monitoring and logging capabilities through the IMS monitoring facilities and the IMS log. Administrators can monitor terminal status, session activity, and security events. Logs provide detailed information for troubleshooting and auditing. This enables proactive management.
