What are the most common commands and their syntax?

Common commands include START COPY, STOP COPY, and REPORT. The START COPY command initiates the online copy process. The STOP COPY command halts an active copy. The REPORT command provides status information.

Can you provide examples of command syntax?

The basic syntax for starting a copy is: START COPY DATABASE(db_name) TABLESPACE(ts_name). The syntax for stopping a copy is: STOP COPY DATABASE(db_name) TABLESPACE(ts_name). The REPORT command syntax is: REPORT COPY DATABASE(db_name).

What configuration files or interfaces are used?

Configuration is managed through JCL (Job Control Language) and control cards. JCL defines the execution environment, and control cards specify parameters such as database names, tablespace names, and copy options. These are submitted to z/OS.

What types of APIs does CDB/Auto-Online Copy expose?

The utility utilizes the DB2 API for interacting with DB2. It does not expose external REST or SOAP APIs. Communication relies on native DB2 interfaces and z/OS system calls.

What is the business value of using CDB/Auto-Online Copy?

CDB/Auto-Online Copy reduces downtime compared to offline backup methods. It allows continuous database availability during backup operations. This results in improved service levels and reduced impact on business operations.

How does CDB/Auto-Online Copy improve resource utilization?

The utility minimizes resource consumption during backup operations. It is designed to be less resource-intensive than some reorganization options. This leads to cost savings and improved system performance.

How does CDB/Auto-Online Copy support business continuity?

By enabling online backups, CDB/Auto-Online Copy supports business continuity and disaster recovery strategies. It ensures that databases can be restored quickly and efficiently. This minimizes data loss and downtime in case of failures.

What security features are provided?

CDB/Auto-Online Copy integrates with DB2's security features. It leverages DB2's authentication and authorization mechanisms. This ensures that only authorized users can initiate and manage backup operations.

How is access control managed?

Access control is managed through DB2's built-in security features. Users must have the necessary DB2 privileges to execute commands. This includes privileges to perform image copies and access database objects.

What audit/logging capabilities exist?

The utility integrates with DB2's auditing capabilities. All backup operations are logged within DB2's audit trails. This provides a record of all backup activities, including who initiated them and when.

What administrative interfaces are available?

Administrative interfaces are primarily through JCL and z/OS system commands. There is no separate GUI or web console. Monitoring is done through DB2 system views and reports generated by the utility.

How is user management handled?

User management is handled through z/OS security and DB2 privileges. Users are authenticated by z/OS and authorized based on their DB2 roles and privileges. This ensures secure access to the utility's functions.

What are the main configuration parameters?

Key configuration parameters include database names, tablespace names, and copy options. These are specified in JCL and control cards. Proper configuration is essential for successful backup operations.

What monitoring/logging capabilities exist?

Monitoring is achieved through DB2 system views and the utility's reporting features. The REPORT command provides status information. DB2 system views offer insights into the backup process.

Product Overview

The architecture of CDB/Auto-Online Copy comprises several key components: the Copy Manager, the Data Mover, and the Logging Agent. The Copy Manager is the central control component, responsible for initiating, monitoring, and managing the backup process. It interacts with DB2 to obtain metadata and coordinate the copy operations.

The Data Mover is responsible for reading data from DB2 data sets and writing the image copies to the specified storage. It utilizes optimized I/O techniques to ensure high-speed data transfer. The Logging Agent works in conjunction with DB2's logging facilities to ensure data consistency during the online copy process.

It monitors the DB2 logs and applies necessary changes to the image copies to maintain a consistent point-in-time backup. Communication between components occurs through z/OS system calls and DB2 internal interfaces. The Copy Manager uses JCL and control cards for configuration, which are submitted to z/OS.

The Data Mover reads data sets and writes image copies to DASD or tape. The Logging Agent interacts with DB2's log to maintain data integrity. The utility supports full, incremental, and differential image copy types.

The primary communication protocol is through DB2's internal mechanisms and z/OS system calls. The utility integrates with DB2's security features, leveraging DB2's authentication and authorization mechanisms. All backup operations are logged within DB2's audit trails.

Frequently Asked Questions

What is CDB/Auto-Online Copy?

CDB/Auto-Online Copy creates online image copies of DB2 databases while the database remains available for read and write operations. This minimizes downtime compared to offline copy utilities. It provides a high-speed backup solution for DB2 on z/OS.

What types of backups does CDB/Auto-Online Copy support?

The utility backs up DB2 data sets, including table spaces and indexes. It supports full, incremental, and differential image copy types. The backups are consistent point-in-time copies of the database.

How does CDB/Auto-Online Copy integrate with DB2?

CDB/Auto-Online Copy integrates with DB2's catalog and directory. It uses DB2's logging facilities to ensure data consistency during the online copy process. The utility interacts directly with DB2 to manage the copy operations.

What automation features are available?

The utility offers automation features, including scheduling and monitoring capabilities. It can be integrated into existing backup and recovery strategies. The automation features reduce manual intervention and improve operational efficiency.
