Question 1

What is DMS/CICS?

Accepted Answer

DMS/CICS is a system designed to generate online CICS application programs with minimal coding. It streamlines the development process by providing tools and features that automate many aspects of application creation. This allows developers to focus on business logic rather than low-level coding details.

Question 2

What platforms does DMS/CICS support?

Accepted Answer

DMS/CICS supports application development on z/OS and zVSE/VSEn platforms. It provides a consistent environment for creating and deploying CICS applications across these mainframe operating systems. This cross-platform support simplifies development and maintenance efforts.

Question 3

How does DMS/CICS simplify application development?

Accepted Answer

DMS/CICS simplifies the creation of online CICS applications by automating many of the repetitive tasks involved in application development. It provides tools for screen design, data definition, and program generation, reducing the amount of manual coding required. This leads to faster development cycles and reduced development costs.

Question 4

How does DMS/CICS integrate with CICS?

Accepted Answer

DMS/CICS was designed to work with CICS environments, allowing developers to create and deploy applications that interact with CICS transactions. It provides features to define and manage CICS resources, such as transactions, programs, and files. This integration streamlines the development of CICS-based applications.

Question 5

What are the common commands and syntax used in DMS/CICS?

Accepted Answer

Common commands include those for screen definition, data definition, program generation, and application compilation. The exact syntax varies depending on the specific operation, but typically involves using DMS/CICS control statements and utilities. For example, screen definition might use a specific syntax to define fields and attributes.

Question 6

What configuration files and interfaces are used by DMS/CICS?

Accepted Answer

DMS/CICS utilizes configuration files to store settings related to application generation and deployment. These files define parameters such as data sources, screen layouts, and program generation options. The specific interfaces used depend on the tasks being performed, including interfaces for screen design and program compilation.

Question 7

What types of APIs does DMS/CICS expose?

Accepted Answer

DMS/CICS does not expose APIs in the modern sense (REST, SOAP). Its functionality is primarily accessed through its command-line interface and control statements. Integration with other systems would typically involve file-based data exchange or custom interfaces built around the generated CICS applications.

Question 8

What are the main system components and how do they communicate?

Accepted Answer

The architecture of DMS/CICS includes components such as the Screen Definition Facility, Data Definition Facility, Program Generator, and Compiler. These components communicate through internal interfaces and data structures. Data is typically stored in mainframe datasets and accessed through CICS file control.

Question 9

What business value did DMS/CICS provide?

Accepted Answer

DMS/CICS accelerated the development of CICS applications by automating many of the manual coding tasks. This resulted in faster development cycles and reduced the need for specialized CICS programming skills. The system's code generation capabilities also helped to standardize application development practices.

Question 10

How did DMS/CICS reduce development costs and improve efficiency?

Accepted Answer

By automating code generation, DMS/CICS reduced the time and effort required to develop and deploy CICS applications. This led to lower development costs and faster time-to-market for new applications. The system's features also helped to improve the quality and consistency of applications.

Question 11

How did DMS/CICS improve application quality and consistency?

Accepted Answer

DMS/CICS provided a structured approach to application development, which helped to improve the quality and consistency of CICS applications. The system's features, such as screen design and data definition tools, ensured that applications adhered to established standards and best practices.

Question 12

How did DMS/CICS help organizations adapt to changing business needs?

Accepted Answer

DMS/CICS enabled organizations to quickly adapt to changing business requirements by simplifying the process of modifying and deploying CICS applications. The system's code generation capabilities allowed for rapid updates and enhancements to existing applications.

Question 13

What authentication methods are supported?

Accepted Answer

DMS/CICS did not have built-in authentication methods in the modern sense. Security was primarily managed through the underlying CICS environment, which provided authentication and authorization mechanisms. This included user ID validation and access control lists (ACLs) for resources.

Question 14

What access control model is used?

Accepted Answer

Access control in DMS/CICS relied on the security features of the CICS environment. This typically involved the use of access control lists (ACLs) to manage access to CICS resources, such as transactions, programs, and files. The CICS security model determined the level of access.

Question 15

What encryption is used and where?

Accepted Answer

DMS/CICS did not provide built-in encryption. Data security was handled by the underlying CICS and mainframe security features. Encryption of data at rest and in transit would be managed through CICS and system-level security configurations.

Question 16

What audit/logging capabilities exist?

Accepted Answer

Audit and logging capabilities were provided by the CICS environment. CICS maintained logs of transactions and system events, which could be used for auditing purposes. DMS/CICS itself did not have its own specific audit logging features.

Question 17

What administrative interfaces are available?

Accepted Answer

Administrative interfaces were primarily command-line based, with users interacting with DMS/CICS through control statements and utilities. There was no graphical user interface (GUI) or web console for administration. Configuration was managed through configuration files and system parameters.

Question 18

How is user management handled?

Accepted Answer

User management was handled through the underlying CICS and mainframe security systems. DMS/CICS did not have its own user management features. User authentication and authorization were managed at the CICS and operating system levels.

Question 19

What are the main configuration parameters?

Accepted Answer

The main configuration parameters were defined in configuration files and system parameters. These parameters controlled aspects such as data sources, screen layouts, and program generation options. The specific parameters varied depending on the DMS/CICS components being used.

Question 20

What monitoring/logging capabilities exist?

Accepted Answer

Monitoring and logging were primarily provided by the CICS environment. CICS provided facilities for monitoring transaction performance and system events. DMS/CICS itself did not have its own dedicated monitoring or logging capabilities.
