Question 11

How does RLX/NET contribute to improved system availability?

Accepted Answer

RLX/NET enables faster response times to critical events and system issues. Its automation capabilities allow for proactive monitoring and automated remediation. This results in improved system availability and reduced impact on business operations.

Question 12

How does RLX/NET help optimize existing infrastructure investments?

Accepted Answer

RLX/NET allows organizations to optimize their existing NetView infrastructure. By leveraging REXX scripting, businesses can customize and extend NetView's functionality to meet specific needs. This maximizes the return on investment in NetView and other related systems.

Question 13

What authentication methods are supported by RLX/NET?

Accepted Answer

RLX/NET supports authentication through z/OS security features, such as RACF, ACF2, and Top Secret. These security products provide user authentication and authorization. The product leverages the underlying z/OS security infrastructure for access control.

Question 14

What access control model is used by RLX/NET?

Accepted Answer

RLX/NET uses the access control mechanisms provided by the z/OS security products (RACF, ACF2, Top Secret). These systems implement role-based access control (RBAC) to manage user permissions and access to resources. This ensures that users only have access to the resources they are authorized to use.

Question 15

What encryption methods are used by RLX/NET?

Accepted Answer

RLX/NET utilizes the security features of the z/OS operating system. Data transmission security relies on the security protocols configured within the z/OS environment. Encryption is handled by the underlying z/OS security infrastructure and any network protocols in use.

Question 16

What audit and logging capabilities are available?

Accepted Answer

RLX/NET integrates with z/OS system logging and security auditing features. Audit trails are generated through the z/OS security products (RACF, ACF2, Top Secret). These logs provide detailed information about user actions and system events, which can be used for security monitoring and incident response.

Question 17

What administrative interfaces are available?

Accepted Answer

Administrative interfaces include the NetView console and the z/OS console. These interfaces allow administrators to start, stop, and monitor RLX/NET processes. Configuration is typically managed through configuration files and system parameters.

Question 18

How is user management handled?

Accepted Answer

User management is handled through the z/OS security system (RACF, ACF2, Top Secret). Administrators manage user accounts, permissions, and access rights within these security products. RLX/NET leverages these existing user management systems.

Question 19

What are the main configuration parameters?

Accepted Answer

Key configuration parameters include settings for resource allocation, security, and communication protocols. These parameters are typically defined in configuration files. The specific parameters depend on the installation and customization of RLX/NET.

Question 20

What monitoring and logging capabilities exist?

Accepted Answer

RLX/NET provides monitoring capabilities through NetView and z/OS system monitoring tools. Logging is provided through z/OS system logs and security audit trails. These features allow administrators to monitor system performance and troubleshoot issues.
