VX/SQL$MOD converts Rdb SQLMOD to Postgres ECPG or Oracle Pro*C, so OpenVMS applications can offload their database to Linux with generated unit tests.


VX/SQL$MOD Enhancements for Seamless Database Migration

Sector7 has enhanced VX/SQL$MOD to generate Postgres ECPG from SQLMOD in addition to Oracle Pro*C. VX/SQL$MOD also generates test drivers for all converted SQLMODs, simplifying unit testing and reducing costs. These unit test drivers can be linked to the original compiled SQLMOD on VMS / OpenVMS, providing robust unit test capabilities for the original SQLMOD. With VX/SQL$MOD, your VMS / OpenVMS application can continue to run on VMS / OpenVMS while offloading the database to a Linux, Windows, or UNIX server running Oracle or Postgres.

Efficient Database Offloading

SQLMOD is converted to Postgres ECPG or Oracle Pro*C on VMS / OpenVMS. By installing the Oracle or Postgres client on VMS / OpenVMS, you can seamlessly convert your Rdb data to Oracle or Postgres and establish a connection between your VMS / OpenVMS system and a Windows, Linux, or UNIX database server.

Reduce Oracle/Rdb License Fees

Interested in lowering your organization's Oracle/Rdb license fees and optimizing VMS / OpenVMS CPU usage? Replace Rdb on your VAX or ALPHA VM and connect to your corporate Oracle or Postgres database for efficient performance and cost savings.
