What interface did DB2 DB/DASD use, and how was it configured?

The tool utilized a command-line interface (CLI) for interaction. Commands were entered directly to perform actions such as displaying storage information and generating reports. Configuration was managed through specific control files.

Can you provide examples of command syntax?

The exact syntax varied depending on the specific command. For example, a command to display storage information might have been formatted as 'DISPLAY STORAGE'. The tool used control files for configuration.

What were the main system components of DB2 DB/DASD?

The system components included a command processor, a data collector, and a reporting engine. These components worked together to gather, process, and present DASD usage data.

How did the components of DB2 DB/DASD communicate with each other?

Communication between components was likely handled through internal system calls and data exchange mechanisms. The data collector gathered information, which the reporting engine then processed.

What was the business value of using DB2 DB/DASD?

DB2 DB/DASD provided value by offering insights into DB2 storage usage, helping administrators optimize storage allocation and potentially reduce costs. It enabled proactive management of DASD resources.

How did DB2 DB/DASD improve database performance?

By monitoring DASD usage, DB2 DB/DASD helped prevent storage-related performance issues. This proactive approach ensured that DB2 databases had sufficient resources to operate efficiently.

How did DB2 DB/DASD assist with capacity planning?

The tool facilitated capacity planning by providing historical data on storage usage trends. This information helped administrators forecast future storage needs and make informed decisions.

What security features did DB2 DB/DASD offer?

Specific security features of DB2 DB/DASD are not well-documented due to its age. However, it likely relied on the underlying z/OS security mechanisms for access control.

How was user management handled in DB2 DB/DASD?

User management was likely handled through the z/OS security infrastructure, such as RACF or similar security products. This allowed for centralized control of user access.

What audit and logging capabilities were available?

Audit and logging capabilities were likely present to track user actions and system events. This functionality was essential for security monitoring and troubleshooting.

What administrative interfaces were available?

Administrative interfaces were primarily command-line based. Administrators interacted with the tool by entering commands to perform various operations.

What monitoring and logging capabilities existed?

Monitoring and logging capabilities were available to track system activity and diagnose issues. These features were crucial for maintaining the tool's functionality.

Product Overview

The architecture of DB2 DB/DASD comprised several key components designed to monitor and manage DASD storage for DB2 databases on z/OS. The main components included a command processor, a data collector, and a reporting engine. The command processor served as the primary interface for user interaction, interpreting and executing commands entered via the command-line interface (CLI).

The data collector was responsible for gathering DASD usage data from DB2 resources. This component collected information on storage allocation, utilization, and performance metrics. The reporting engine processed the data collected by the data collector and generated reports.

These reports provided insights into storage usage trends, potential performance bottlenecks, and capacity planning information. Communication between components was likely handled through internal system calls and data exchange mechanisms. Configuration was managed through control files.

These files allowed administrators to customize the tool's behavior and specify various settings. DB2 DB/DASD is no longer supported. The DB2 Storage Management Utility is the recommended replacement.

Frequently Asked Questions
