Automated Data Migration for Mainframe to Open Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The migration of operations from mainframes to open systems is hindered by the lack of automation in data migration, resulting in significant input/output overhead due to differences in data storage formats and character codes between mainframes and open systems.
Innovation Solution
A computer apparatus and system that includes a use state analysis unit to acquire data usage history and a data migration unit to extract and migrate data to a destination system, converting formats as necessary, allowing for automated data migration without disrupting operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data migration is performed manually using conventional technologies, then data can be migrated between mainframes and open systems, but the process is time-consuming and requires stopping operations
Solution Approach 1:
The system performs preliminary analysis of data usage history and migration requirements before actual migration. The use state analysis unit acquires information about which data is actually used, and the migration determination unit pre-determines the migration plan, allowing migration to proceed automatically without operational interruption.
Solution Approach 2:
The migration system performs self-service by automatically analyzing data usage patterns, determining migration requirements, and executing data migration without human intervention. The system autonomously identifies which data to migrate and performs the migration while operations continue uninterrupted.
2Productivity
If all data is migrated from mainframe to open system, then complete migration is achieved, but unnecessary data transfer increases overhead and time consumption
Solution Approach 1:
The system extracts only the necessary data for migration by analyzing data usage history. The use state analysis unit identifies which data is actually accessed and used, and the migration determination unit extracts only those specific data items, excluding unnecessary data from the migration process.
Solution Approach 2:
The system applies different treatment to different data based on its usage characteristics. Rather than uniform migration of all data, the system selectively migrates only the data that has actual usage value, treating each data item according to its specific usage pattern and importance.
3Adaptability or versatility
If data storage formats and character codes are converted during migration, then compatibility between mainframes and open systems is achieved, but conversion overhead increases processing time
Solution Approach 1:
The system performs format and character code conversion in advance during the automated migration process. By using the acquired data usage information to guide the conversion process, the system prepares data in the target format before it is needed, reducing actual conversion time during operations.

AI summary
A computer system includes a use state analysis program that acquires a use history of data in a first computer system and a program that uses the data; and a data migration program that extracts data that is able to be migrated from the first computer system to a second computer system on the basis of the use history, writes the migratable data to a first storage system and a second storage system, and migrates a program to the second computer system on the basis of a use history of the data used by the program.
