Question 2

Accepted Answer

LegacyAda/390 is a compiler and development environment for the Ada 83 programming language, designed for the z/OS and z/VM platforms. It enables developers to write, compile, and execute Ada code within the IBM mainframe environment.

Question 3

What are the key benefits of using LegacyAda/390?

Question 4

Accepted Answer

Key benefits include the ability to leverage the robustness and reliability of Ada 83 for critical applications, integration with the z/OS and z/VM operating systems, and access to mainframe resources. It provides a stable environment for developing and maintaining legacy Ada applications.

Question 5

What types of applications are suitable for LegacyAda/390?

Question 6

Accepted Answer

LegacyAda/390 is well-suited for developing and maintaining applications that require high reliability, safety, and security. This includes applications in areas such as finance, defense, and aerospace, where the integrity of the code is paramount.

Question 7

How does LegacyAda/390 compare to other programming languages on the mainframe?

Question 8

Accepted Answer

Compared to other mainframe languages, LegacyAda/390 offers strong typing, modularity, and exception handling, which contribute to more robust and maintainable code. It differs from languages like COBOL and PL/I in its emphasis on software engineering principles and safety.

Question 9

What are the main components of the LegacyAda/390 environment?

Question 10

Accepted Answer

The main components include the Ada compiler, linker, runtime libraries, and debugging tools. These components work together to translate Ada source code into executable programs and provide the necessary support for program execution and debugging.

Question 11

What is the typical command structure for compiling an Ada program?

Question 12

Accepted Answer

The typical command structure involves using the compiler to translate the source code into object code, followed by linking the object code with necessary libraries to create an executable. For example, the command 'ada -c myprogram.ada' compiles the source file, and 'ada myprogram.o' links the object file.

Question 13

What configuration files or interfaces are used in LegacyAda/390?

Question 14

Accepted Answer

Configuration files are used to set compiler options, specify include paths, and define library locations. These files allow developers to customize the compilation process. Interfaces include the standard input/output streams and system-specific APIs for interacting with the operating system.

Question 15

What debugging tools are available for LegacyAda/390?

Question 16

Accepted Answer

Debugging tools include source-level debuggers that allow developers to step through code, inspect variables, and set breakpoints. These tools help in identifying and resolving errors in Ada programs. The debugger is typically invoked through commands that specify the executable to debug.

Question 17

How does LegacyAda/390 contribute to business value?

Question 18

Accepted Answer

LegacyAda/390 enables businesses to maintain and modernize critical applications written in Ada 83. By providing a stable and reliable environment, it reduces the risk of application failures and supports the continued operation of essential business functions.

Question 19

What are the cost benefits of using LegacyAda/390?

Question 20

Accepted Answer

The cost benefits include the ability to leverage existing Ada code, reduce the need for costly rewrites, and maintain applications on a stable platform. This can lead to lower development and maintenance costs compared to migrating to other languages.

Question 21

How does LegacyAda/390 support compliance and security?

Question 22

Accepted Answer

LegacyAda/390 supports compliance by enabling the development of secure and reliable applications. The Ada language's features, such as strong typing and modularity, contribute to building systems that meet stringent security requirements.

Question 23

What is the return on investment (ROI) of using LegacyAda/390?

Question 24

Accepted Answer

The ROI is realized through the preservation of existing investments in Ada code, reduced maintenance costs, and the ability to adapt to changing business needs. The stability and reliability of the platform contribute to a higher ROI.

Question 25

What authentication methods are supported by LegacyAda/390?

Question 26

Accepted Answer

LegacyAda/390 itself does not directly handle authentication. Authentication is typically managed at the operating system level (z/OS or z/VM) through methods such as RACF or other security products. The Ada applications then interact with these security mechanisms.

Question 27

What access control model is used?

Question 28

Accepted Answer

Access control is managed by the underlying operating system (z/OS or z/VM), which typically uses an access control list (ACL) or role-based access control (RBAC) model. Ada applications utilize the security features provided by the operating system.

Question 29

What encryption is used?

Question 30

Accepted Answer

Encryption is typically handled by the operating system or external security products. LegacyAda/390 applications can utilize system APIs to encrypt and decrypt data. The specific encryption algorithms depend on the security configuration of the mainframe.

Question 31

What audit/logging capabilities exist?

Question 32

Accepted Answer

Audit and logging capabilities are provided by the operating system and security products. LegacyAda/390 applications can generate log entries using system calls. These logs are then used for auditing and security monitoring.

Question 33

What administrative interfaces are available for LegacyAda/390?

Question 34

Accepted Answer

Administration is primarily performed through the z/OS or z/VM operating system interfaces, including the TSO/E command line and system management tools. There is no dedicated GUI for LegacyAda/390 itself.

Question 35

How is user management handled?

Question 36

Accepted Answer

User management is handled through the z/OS or z/VM operating system. User accounts, permissions, and access rights are managed using system utilities such as RACF or equivalent security products.

Question 37

What are the main configuration parameters?

Question 38

Accepted Answer

The main configuration parameters include compiler options, library paths, and environment variables. These parameters are set through configuration files and system settings to customize the compilation and execution environment.

Question 39

What monitoring and logging capabilities exist?

Question 40

Accepted Answer

Monitoring and logging are primarily handled by the operating system. LegacyAda/390 applications can write to system logs using standard output or system calls. System monitoring tools can be used to track resource usage and application performance.
