What problem does this product solve?

IMS High Performance Prefix Resolution is a utility designed to resolve prefixes in IMS databases after database loads and reorganizations. It ensures the logical relationships between database resources are correctly maintained, which is critical for data integrity and application functionality.

How does this product improve IMS database operations?

The product addresses the need to efficiently and accurately update prefix pointers in IMS databases. Without proper prefix resolution, applications may encounter data access errors or incorrect results due to broken logical relationships.

What are the key benefits of using this product?

By automating and optimizing the prefix resolution process, the product reduces the time and effort required for database maintenance. This leads to improved database availability and reduced operational costs.

What is the command structure for basic operations?

The main components include the Prefix Resolution Engine, the Control Program, and the Input/Output Processor. These components work together to analyze, process, and update the database prefixes.

What configuration files or interfaces are used?

Common commands include RESOLVE, CHECK, and REPORT. The syntax typically involves specifying the database name and other parameters. For example, RESOLVE DATABASE(DBNAME) or CHECK DATABASE(DBNAME) REPORT(SUMMARY).

What databases or storage mechanisms are used?

Configuration is primarily managed through control cards and parameter datasets. These define the databases to be processed, the processing options, and the output destinations. There is no GUI interface.

What protocols does it use for communication?

The product directly interacts with IMS databases, including HDAM, HIDAM, and HISAM. It reads and writes to the database structures to update prefix pointers.

What is the impact on database availability?

By automating prefix resolution, the product reduces the manual effort required for database maintenance. This leads to fewer errors, faster processing times, and reduced need for specialized skills, lowering overall operational costs.

How does this product improve data integrity?

The product helps maintain database availability by ensuring data integrity after database operations. By quickly resolving prefixes, it minimizes downtime and prevents data access issues.

What are the key metrics to measure the product's success?

By accurately resolving prefixes, the product ensures that logical relationships within the database are correctly maintained. This prevents data corruption and ensures that applications can access the correct data.

What access control model is used?

The product does not have built-in authentication methods. Security is managed through the z/OS environment and IMS security features.

What audit/logging capabilities exist?

Access control is managed through the z/OS security system, such as RACF or equivalent. Users are granted access to datasets and resources based on their roles and permissions defined within the security system.

The product generates logs that record the operations performed, including the databases processed, the actions taken, and any errors encountered. These logs can be used for auditing and troubleshooting.

How is user management handled?

The primary administrative interface is through JCL (Job Control Language) and control cards. There is no GUI or web console available.

What are the main configuration parameters?

User management is handled through the z/OS security system. Access to the product's datasets and execution is controlled via security profiles.

What monitoring/logging capabilities exist?

Configuration parameters are specified in control cards and parameter datasets. These parameters define the databases to be processed, processing options, and output destinations.

Product Overview

The architecture of IMS High Performance Prefix Resolution centers around three main components: the Prefix Resolution Engine, the Control Program, and the Input/Output Processor. The Prefix Resolution Engine is the core component responsible for analyzing and updating the database prefixes. The Control Program manages the overall execution flow, including job control and error handling.

The Input/Output Processor handles the interaction with the IMS databases, reading and writing data as needed. These components communicate through internal interfaces and data structures. The product operates within the z/OS environment and interacts directly with IMS databases, including HDAM, HIDAM, and HISAM.

Configuration is managed through control cards and parameter datasets, which specify the databases to be processed, processing options, and output destinations. There are no external APIs. The product uses JCL for job submission and control.

Security is managed through the z/OS security system, such as RACF, which controls access to datasets and resources. Logging provides detailed information for auditing and troubleshooting. The product's design focuses on efficient prefix resolution, ensuring data integrity and minimizing downtime during database maintenance.

It does not offer features like REST APIs or GUI interfaces, which are common in some competing products. The product's strength lies in its direct integration with IMS and its ability to handle large-scale prefix resolution tasks.
