Non-intrusive C/C++ Middleware Transaction Instrumentation, Zero Failure Project (2006 – 2010)

Overview

Ensuring stable operations in mission-critical enterprise software requires more than conventional monitoring. This project established an always-on transaction tracing framework that detected performance anomalies early, reducing downtime in high-stakes manufacturing execution systems (MES).

• Delivered a function-intercept-based middleware monitoring system, enabling real-time observability of enterprise applications.
• Technology delivered as a core enabling feature that made TmaxSoft strike a 2 billion KRW (approx. 1.5 million dollars) project building a fault monitoring & troubleshooting system for LG Display’s mission critical manufacturing execution system (MES)

Technology

• LD_PRELOAD based system call intercept for packet modification and tracking
• LD_PRELOAD based library intercept for Oracle OCI, Tibco, Tmax, BEA Tuxedo
• Lock-free queue on POSIX shared memory for low-overhead IPC
• Data ingest to Oracle RDBMS backend
• HP-UX, Solaris, AIX, Linux
