COBOL with DB2 and Embedded SQL to Java

SoftwareMining provides automated, rule-based tools for converting COBOL applications that use DB2 and embedded EXEC SQL into maintainable Java or C# source code. The tools support SQL statements, host variables, cursors, SQLCODE handling and database transactions while preserving the surrounding COBOL business logic.

The generated application uses readable, object-oriented code and standard database-access technologies. It can continue using DB2 or be adapted for another relational database, supporting deployment on cloud or private infrastructure.

Mission-critical applications do not need to be migrated in a single deployment. A phased approach can allow converted Java components to operate alongside the remaining COBOL system. See our incremental COBOL-to-Java migration strategy for a controlled rollout approach.

Key Features of SoftwareMining's DB2 COBOL Translation

• SQL Dialect Conversion

  SoftwareMining automatically converts embedded SQL from COBOL syntax to Java or C#. It replaces COBOL host variables such as :FIELD with parameter formats used in Java ('?') or C# ('@'), ensuring compatibility with modern frameworks.

• Database Vendor Flexibility

  After migration, organizations can switch databases - for example, from DB2 to Oracle or MySQL. SoftwareMining supports runtime configuration of SQL return codes, allowing smooth database substitution without code changes.

• Migrating COBOL Stored Procedures

  The translator converts COBOL-based stored procedures into Java or C# equivalents compatible with Oracle, DB2, and Microsoft SQL Server. These procedures gain object orientation, structured exception handling, and easier maintenance.

• Optimized Batch Performance

  Many SQL-based COBOL systems run as daily batch jobs with strict deadlines. SoftwareMining optimizes the translated code by removing unnecessary database calls and replacing them with Java or C# library functions. This reduces network overhead while preserving identical results.
