Accepted Answer

CICS JS/Server is designed to be highly scalable, capable of handling a large number of concurrent users and requests. Performance is optimized through efficient resource management within the CICS environment. The server's architecture allows for easy scaling to meet growing demands.

Question 11

What cost savings can be realized by using CICS JS/Server?

Accepted Answer

CICS JS/Server can reduce costs by enabling developers to reuse existing mainframe infrastructure and skills. By leveraging Javascript libraries, developers can build modern user interfaces without requiring extensive mainframe-specific expertise. This can lead to faster development cycles and lower overall project costs.

Question 12

What specific authentication methods are supported? What access control model is used? What encryption is used and where? What audit/logging capabilities exist?

Question 13

What specific authentication methods are supported?

Accepted Answer

CICS JS/Server leverages CICS security features for authentication, including RACF, and other security managers integrated with CICS. It supports role-based access control (RBAC) through CICS security definitions. Encryption is handled by CICS for secure communication. Detailed audit logging is provided through CICS system logs and JS/Server-specific logs.

Question 14

What access control model is used?

Accepted Answer

Access control is managed through CICS security definitions, allowing for role-based access control (RBAC). This enables administrators to define roles and assign permissions to users, controlling access to Javascript libraries and server functions. This model provides a flexible and secure way to manage user access.

Question 15

What encryption is used and where?

Accepted Answer

Encryption is primarily handled by CICS, ensuring secure communication. This includes encryption of data in transit using HTTPS and other secure protocols. The specific encryption algorithms used depend on the CICS configuration and security policies.

Question 16

What audit/logging capabilities exist?

Accepted Answer

Comprehensive audit logging is provided through CICS system logs and specific JS/Server log files. These logs record user actions, configuration changes, and security events. This allows for detailed monitoring and auditing of server activity.

Question 17

What are the key operational considerations for CICS JS/Server? How is the server monitored for performance and availability? What are the best practices for managing Javascript library deployments? How are updates and patches applied to CICS JS/Server? What are the common troubleshooting steps for CICS JS/Server?

Question 18

What are the key operational considerations for CICS JS/Server?

Accepted Answer

Operational considerations include monitoring server performance, managing Javascript library deployments, and ensuring secure access. Regular backups of configuration files and libraries are essential. Proper planning for capacity and resource allocation within the CICS environment is also important.

Question 19

How is the server monitored for performance and availability?

Accepted Answer

The server is monitored using CICS system monitoring tools and specific JS/Server metrics. Performance metrics include CPU usage, memory consumption, and response times. Availability is monitored through CICS health checks and alerts. Proactive monitoring helps ensure optimal performance and availability.

Question 20

What are the best practices for managing Javascript library deployments?

Accepted Answer

Best practices include version control for Javascript libraries, proper testing before deployment, and careful management of dependencies. Use the CLI tools for deployment and ensure that access control lists are correctly configured. Regular audits of library versions and security settings are recommended.

Question 21

How are updates and patches applied to CICS JS/Server?

Accepted Answer

Updates and patches are applied through standard CICS maintenance procedures. Follow vendor-provided instructions for applying updates. Ensure that proper testing is performed after applying updates to verify functionality and compatibility. Backups should be performed before applying any updates.
