Product Overview

Eclipse iLoad was a high-speed IMS database load utility operating on z/OS. Its architecture comprised a load engine, data validation routines, and I/O management modules. These components communicated through internal subroutine calls and shared memory.

Data was stored in z/OS datasets and IMS databases. The utility was configured via JCL and control cards, defining input datasets and target databases. It integrated with z/OS security systems like RACF for authentication and authorization.

It did not expose modern APIs (REST, SOAP); integration relied on JCL-based execution. Given its unsupported status, a migration to alternatives is necessary. IBM IMS High Performance Load offers a direct replacement.

BMC Load Plus for IMS and Rocket MainView Reorg for IMS provide enhanced features. Migration involves re-architecting JCL workflows and adapting control cards. Ensure that security profiles are migrated to the new solution.

Consider ASG-TMON for IMS for comprehensive IMS management, including data loading.

Frequently Asked Questions

What was the primary function of Eclipse iLoad?

Eclipse iLoad was a high-speed utility designed to load IMS databases. It streamlined the process of populating IMS databases, reducing the time and resources required compared to standard methods. It was part of a suite of reorganization utilities.

What types of IMS databases did Eclipse iLoad support?

The utility supported various IMS database structures, including full-function databases and DEDBs. It could handle different data formats and provided options for data validation and transformation during the load process. It optimized I/O operations to maximize throughput.

How was Eclipse iLoad configured for a specific load operation?

While specific configuration files varied, users typically defined control cards specifying the input data source, target IMS database, and any data transformation rules. These control cards were processed by the iLoad utility to manage the load operation. JCL was used to execute the load jobs.

How did Eclipse iLoad interact with the z/OS and IMS environments?

Eclipse iLoad used standard z/OS system services for I/O operations and data access. It interacted directly with the IMS control region to manage database updates. It leveraged z/OS utilities for data sorting and manipulation.
