What are the common commands and syntax?

While specific command syntax is dependent on the MASTER-UTIL suite version, common operations involve specifying the DB2 objects (tablespaces, partitions) to be copied, defining the output dataset names, and setting options for incremental copy and log application.

What configuration files are used?

MasterCopySet likely uses configuration files to define parameters such as dataset naming conventions, storage locations, and performance tuning options. These files are typically customized to match the specific DB2 environment.

What is the business value of MasterCopySet?

By creating image copies independently of DB2, MasterCopySet minimizes the impact on DB2 transaction processing and overall system performance. This allows for more frequent backups without disrupting critical business applications.

How does MasterCopySet improve recovery times?

Faster backup times translate to reduced downtime during recovery scenarios. The ability to quickly restore DB2 objects from image copies minimizes the impact of data loss events.

How is security handled?

MasterCopySet likely leverages the security features of the z/OS operating system, including RACF or ACF2, for authentication and authorization. Access to the utility and its functions is controlled through these security systems.

What access control model is used?

The access control model is likely based on role-based access control (RBAC), where users are assigned roles with specific permissions to perform certain tasks within MasterCopySet.

What audit/logging capabilities exist?

Audit logging is a standard feature, recording all actions performed within MasterCopySet, including user logins, command executions, and data access events. These logs are essential for security monitoring and compliance.

What administrative interfaces are available?

Administrative interfaces likely include a command-line interface (CLI) for batch processing and automation, and potentially a GUI or web console for interactive management. The CLI is commonly used for scheduling backups and restores.

How is user management handled?

User management is typically handled through the z/OS security system (RACF or ACF2), where user accounts and permissions are defined. MasterCopySet integrates with these systems to enforce access control policies.

What monitoring/logging capabilities exist?

Monitoring and logging capabilities include real-time status displays, historical performance data, and detailed error messages. These features help administrators identify and resolve issues quickly.

MasterCopySet for DB2 on z/OS

Infotel Supported z/OS

Backup and Restore Performance Db2

Vendor

Product Overview

MasterCopySet for DB2 on z/OS provides independent image copy creation, allowing DB2 processing to continue uninterrupted. It is a part of the MASTER-UTIL suite. It leverages existing DB2 full image copies, incremental image copies, and DB2 logs to create a consistent full image copy.

This approach minimizes performance impact during backups. The architecture likely involves a main control component that orchestrates the image copy process, data mover components that read and write data, and log processing components that apply changes from the DB2 logs. These components communicate through z/OS system services.

The utility integrates with z/OS security (RACF/ACF2) for authentication and authorization. The access control model is based on role-based access control (RBAC). Administrative interfaces include a command-line interface (CLI) for batch processing and a GUI for interactive management.

User management is handled through z/OS security. Configuration parameters are typically stored in configuration files. Monitoring and logging capabilities include real-time status displays and historical performance data.

Competing products include IBM Db2 Utilities Suite and BMC AMI Copy Plus. MasterCopySet distinguishes itself by creating image copies independently from DB2, unlike some competitors that may require DB2 involvement.

Frequently Asked Questions

What problem does MasterCopySet solve?

MasterCopySet creates full image copies independently of DB2, allowing DB2 processing to continue uninterrupted. It leverages existing DB2 full image copies, incremental image copies, and DB2 logs to create a consistent full image copy.

How does MasterCopySet create full image copies?

MasterCopySet uses a combination of the last DB2 full image copy, incremental image copies, and DB2 logs to create a full image copy. This approach minimizes the impact on DB2 performance during the image copy process.

How does MasterCopySet relate to the MASTER-UTIL suite?

MasterCopySet integrates with the broader MASTER-UTIL suite, providing a comprehensive set of utilities for DB2 management and optimization.
