How does CDB/Application Recovery differ from standard DB2 backup and restore?

CDB/Application Recovery enables the point-in-time recovery of DB2 objects. It allows users to restore a consistent state of a database or a subset of objects to a specific point in time, which is crucial for disaster recovery and data corruption scenarios.

What types of DB2 objects can be recovered using CDB/Application Recovery?

Unlike standard DB2 backup and restore, CDB/Application Recovery focuses on application-consistent recovery. It allows for the recovery of specific objects or sets of objects to a particular point in time, providing more granular control and faster recovery times compared to restoring an entire database.

What are the key benefits of using CDB/Application Recovery?

CDB/Application Recovery supports the recovery of a wide range of DB2 objects, including tables, indexes, table spaces, and databases. The specific objects supported depend on the configuration and the DB2 environment.

Is CDB/Application Recovery suitable for all DB2 environments?

Key benefits include reduced downtime, improved data consistency, and the ability to recover from logical errors or data corruption. It provides a more efficient and targeted approach to recovery compared to full database restores.

What is the role of the Recovery Manager?

The main components include the Recovery Manager, the Object Catalog, and the Data Mover. The Recovery Manager coordinates the recovery process, the Object Catalog tracks object metadata, and the Data Mover handles data transfer.

What are the network requirements for CDB/Application Recovery?

CDB/Application Recovery ensures transaction consistency by applying logs to the recovered data. It uses the DB2 transaction logs to roll forward or backward transactions, ensuring that the recovered data is in a consistent state at the recovery point.

What is the impact of CDB/Application Recovery on data consistency?

By enabling the recovery of specific objects or sets of objects, CDB/Application Recovery minimizes the amount of data that needs to be restored. This targeted approach significantly reduces the time required for recovery compared to restoring an entire database.

How does CDB/Application Recovery improve data protection?

CDB/Application Recovery ensures data consistency by applying transaction logs to the recovered data. This process guarantees that the recovered data is in a consistent state, preventing data corruption and ensuring data integrity.

What are the cost benefits of using CDB/Application Recovery?

CDB/Application Recovery enhances data protection by providing a mechanism to recover from logical errors, data corruption, and other data loss scenarios. It allows users to restore data to a known good state, minimizing the impact of data-related incidents.

What access control model is used?

CDB/Application Recovery supports authentication through the z/OS security infrastructure, including RACF, allowing integration with existing security policies and user management systems.

What encryption is used?

CDB/Application Recovery uses role-based access control (RBAC) to manage user permissions. Users are assigned roles that define their access rights to specific functions and data within the system.

What audit/logging capabilities exist?

Data encryption is supported during data transfer and storage. The specific encryption algorithms used depend on the configuration and the security policies of the environment.

How is user management handled?

CDB/Application Recovery provides a command-line interface (CLI) for administrative tasks. The CLI allows users to perform various operations, such as initiating recovery jobs, managing object catalogs, and monitoring system status.

What are the main configuration parameters?

User management is integrated with the z/OS security infrastructure. User accounts and permissions are managed through RACF or a similar security system, ensuring consistent access control across the environment.

What monitoring/logging capabilities exist?

The main configuration parameters include settings for backup locations, object catalog locations, and logging levels. These parameters can be configured through the CLI or configuration files.

Product Overview

The architecture of CDB/Application Recovery is designed for efficient and reliable point-in-time recovery of DB2 objects on z/OS. The core components include the Recovery Manager, the Object Catalog, and the Data Mover. The Recovery Manager is the central component, responsible for coordinating the recovery process.

It analyzes backup data, identifies the objects to be recovered, and orchestrates the actions of the other components to restore the data to the specified point in time. The Object Catalog maintains metadata about the DB2 objects, including their structure, location, and backup history. This catalog is essential for identifying the objects to be recovered and for ensuring data consistency.

The Data Mover is responsible for transferring data between the backup storage and the target DB2 environment. It handles the physical movement of data and ensures that the data is restored in a consistent and efficient manner. Communication between components occurs via internal interfaces and uses TCP/IP for data transfer.

The system integrates with the z/OS security infrastructure for authentication, using RACF or similar systems. RBAC is used for access control, with roles defining user permissions. The CLI is the primary administrative interface, allowing for the configuration of backup locations, object catalog locations, and logging levels.

Compared to competing products, CDB/Application Recovery offers more granular control and faster recovery times by focusing on specific objects.
