Our production system runs on Actian Ingres 11.2 with a front-end written in OpenROAD 6.2. The codebase has begun to show its age, and I now need regular maintenance that focuses on two fronts: squashing existing bugs and delivering small, well-scoped feature updates that keep the application relevant for our users. Current pain points • Functional errors inside the data-processing routines occasionally crash long-running jobs. • Data-integrity problems in the reporting module create mismatched totals and duplicate rows. Scope of work 1. Investigate and resolve those functional and data-integrity issues. A short write-up explaining root cause, steps to reproduce, and the applied fix must accompany every patch. 2. Implement agreed-upon feature enhancements without disrupting existing workflows. Each new feature should follow our present OpenROAD 6.2 GUI conventions and leverage native Ingres capabilities whenever possible. 3. Provide clean, version-controlled source updates along with an incremental database script (DDL/DML) so I can promote the changes through staging to production. 4. Run basic performance and regression tests after each change to confirm that no new errors appear in data processing or reporting. Acceptance criteria • All critical jobs in the data-processing layer complete without runtime errors. • Report outputs match the underlying tables with zero duplicate or missing records. • New features compile and run on a vanilla Ingres 11.2/OpenROAD 6.2 setup. • A concise change log and rollback script are supplied for every delivery. I handle deployment myself, so the deliverable is limited to patched source, scripts, and documentation. If you have deep experience with Actian Ingres internals, Embedded SQL, and the OpenROAD 4GL, you will feel right at home on this project.

Your system doesn’t need a rewrite - it needs precise, low-risk fixes that stabilize jobs and restore data integrity. I specialize in legacy systems where correctness, traceability, and zero-regression delivery are critical. I will debug Ingres/OpenROAD routines at the SQL and 4GL layers, isolating root causes for job crashes and reporting inconsistencies. Each fix includes reproducible steps, targeted patches, and validation queries to ensure no duplicate or missing records. Feature updates will follow existing OpenROAD GUI patterns and leverage native Ingres capabilities to avoid unnecessary complexity. I’ll deliver version-controlled source, incremental DDL/DML scripts, and rollback-safe changes. I also run regression and performance checks after every update to guarantee stability across data-processing workflows. Happy to align on a maintenance cadence and start with a focused audit of your current issues.

Hello, I have experience with Actian Ingres and OpenROAD, having built data-processing pipelines with transaction rollback handling and reporting modules with checksum validation to prevent duplicate rows. For your crashing jobs, I would implement structured exception handling with logging to capture the exact failure point, then trace the data flow to identify integrity violations. Each fix would include documented root cause analysis and reproduction steps. For the reporting mismatches, I would audit the aggregation logic and add constraint checks. Let's discuss!

Hey, how is it going? Your stack is very specific, and that matters here because this is not generic legacy maintenance. Actian Ingres 11.2 with an OpenROAD 6.2 front end needs someone who understands how data logic, Embedded SQL, 4GL behavior, and reporting routines interact before touching anything. I can help on both fronts you outlined: fixing the runtime failures in long-running data processing jobs and resolving the reporting issues causing duplicate rows and mismatched totals. My approach would be to trace execution paths, isolate bad joins or transaction handling, review temp table usage, and verify how record state moves through each routine so the fix is stable, not cosmetic. For feature work, I can add small scoped enhancements while preserving existing GUI conventions and native Ingres patterns, which is usually the safest path on systems like this. Each patch can be delivered with clean source updates, incremental DDL or DML scripts, rollback scripts, root cause notes, and brief reproduction steps. I also understand that regression safety is critical here, so i would run focused testing around batch jobs, reports, and changed modules before handoff. I am comfortable working in older enterprise codebases where careful changes matter more than flashy rewrites. I'm ready here for you, Let's chat! Mike
