Recovery Analyzer for Db2 Modernization Guide

Recovery Analyzer for Db2 automates the creation of Db2 database and system recovery jobs. It analyzes the Db2 environment and generates the necessary JCL to recover databases and systems to a consistent point in time, reducing manual effort and potential errors.

Recovery Analyzer is a tool set designed to automate and simplify Db2 recovery processes. It provides the functionality to analyze the Db2 environment, identify recovery requirements, and generate the necessary jobs for database and system recovery.

Organizations that rely on Db2 for their critical data and require efficient and reliable recovery processes benefit most from Recovery Analyzer. This includes enterprises in industries such as banking, finance, insurance, and retail.

A company should consider Recovery Analyzer when they need to improve their Db2 recovery time, reduce the risk of human error in recovery processes, and streamline their disaster recovery planning. It is especially useful in complex Db2 environments with many databases and tablespaces.

Alternatives to Recovery Analyzer for Db2 include manual JCL creation, other Db2 recovery tools such as Db2 Recovery Expert, and custom scripting. However, these alternatives may lack the automation and comprehensive analysis capabilities of Recovery Analyzer.

Recovery Analyzer for Db2 runs on the z/OS platform and requires access to the Db2 subsystem. It utilizes Db2 catalog information and log data to analyze the recovery requirements and generate the necessary JCL.

Recovery Analyzer for Db2 runs in an LPAR on z/OS. It is dependent on the z/OS operating system and requires access to specific z/OS subsystems, including Db2.

Recovery Analyzer analyzes Db2 logs, the Db2 catalog, and other system information to determine the appropriate recovery steps. It then generates JCL to perform image copies, log applies, and other necessary recovery actions.

Recovery Analyzer integrates with Db2 by directly accessing the Db2 catalog and reading Db2 logs. It uses standard Db2 APIs and interfaces to gather information about the Db2 environment and generate recovery JCL.

Recovery Analyzer provides significant business value by reducing the time and effort required to recover Db2 databases and systems. This leads to faster recovery times, reduced downtime, and improved business continuity.

By automating the creation of recovery jobs, Recovery Analyzer reduces the risk of human error in the recovery process. This ensures that recovery operations are performed correctly and consistently, minimizing the potential for data loss or corruption.

Recovery Analyzer helps organizations meet their recovery time objectives (RTOs) by automating and streamlining the recovery process. This enables them to recover their Db2 databases and systems more quickly and efficiently, minimizing the impact of outages on the business.

Recovery Analyzer leverages the security features of z/OS and Db2 to control access to sensitive data and recovery functions. It supports standard z/OS authentication methods and integrates with z/OS security systems such as RACF, ACF2, and Top Secret.

Recovery Analyzer uses the z/OS access control model to restrict access to its functions and data. This ensures that only authorized users can perform recovery operations or access sensitive information.

Recovery Analyzer provides audit logging capabilities to track all recovery-related activities. This allows organizations to monitor and audit recovery operations to ensure compliance with security policies and regulations.

Recovery Analyzer requires ongoing monitoring to ensure that it is functioning correctly and that recovery jobs are being generated as expected. This includes monitoring the system logs, job execution status, and any error messages.

Implementing Recovery Analyzer can be challenging due to the complexity of Db2 environments and the need to properly configure the tool to meet specific recovery requirements. Thorough testing and validation are essential to ensure that recovery jobs are generated correctly.

Recovery Analyzer is typically deployed on-premise, within the z/OS environment where Db2 is running. It is installed as a set of load modules and JCL procedures that are executed on the mainframe.
