High Performance Recovery for IMS Modernization Guide

High Performance Recovery for IMS is a utility designed to facilitate rapid recovery of IMS databases. It uses change accumulation and log data to restore databases to a consistent state, minimizing downtime and data loss.

This is a specialized toolset focused on database recovery within the IMS environment. It provides functionalities beyond standard backup and restore, including point-in-time recovery and change accumulation application.

Organizations that rely on IMS databases for critical business operations, particularly those in industries with stringent data availability requirements such as banking, finance, and insurance, benefit most from this product.

Consider using High Performance Recovery for IMS when you need to minimize downtime during database recovery, require point-in-time recovery capabilities, or want to streamline the recovery process using change accumulation and log data.

Alternatives include native IMS recovery utilities and other third-party recovery tools. However, High Performance Recovery for IMS distinguishes itself through its change accumulation functionality and ISPF-based job creation tools.

High Performance Recovery for IMS operates within the z/OS environment and requires access to IMS subsystems. It leverages change accumulation files and IMS logs for recovery operations.

Yes, it runs within an LPAR under z/OS. It is tightly integrated with the IMS subsystem and relies on z/OS system services for its operation.

The product enhances IMS by providing advanced recovery capabilities. It is not a standalone product but rather extends the functionality of the IMS database management system.

It requires access to IMS logs and change accumulation datasets. The specific datasets and their naming conventions must be configured for the product to function correctly.

The product minimizes downtime during IMS database recovery, ensuring business continuity. Its point-in-time recovery feature allows restoring databases to a specific state, preventing data loss.

By streamlining the recovery process and reducing downtime, the product helps organizations meet service level agreements (SLAs) and avoid financial losses associated with system outages.

The ISPF tools simplify the creation of restore jobs, reducing the need for manual scripting and minimizing the risk of errors. This improves operational efficiency and reduces the workload on database administrators.

The product leverages z/OS security features for authentication and authorization. Access to IMS datasets and recovery functions is controlled through standard z/OS security mechanisms.

It integrates with z/OS security systems such as RACF, ACF2, or Top Secret to control access to sensitive data and recovery functions. This ensures that only authorized personnel can perform recovery operations.

The product provides audit trails of recovery operations, logging who performed the recovery, when it was performed, and what data was affected. This helps organizations meet compliance requirements and track recovery activities.

The product is typically deployed on-premise within the z/OS environment. It requires experienced mainframe personnel to install, configure, and operate.

Ongoing operational requirements include monitoring recovery jobs, managing change accumulation datasets, and ensuring the availability of IMS logs. Regular maintenance is needed to keep the product running smoothly.

Implementation challenges often involve configuring the product to work with existing IMS environments, ensuring proper dataset naming conventions, and training personnel on the use of the ISPF tools.
