Open J Proxy
Open J Proxy
Enterprise-grade database connection management for Java applications
The intelligent JDBC Type 3 driver that transforms your database connectivity
The OJP JDBC Driver is a drop-in replacement for your existing JDBC driver that routes all database traffic through the Open J Proxy server. This architecture provides centralized connection pooling, intelligent load management, and protection against connection storms - all without changing a single line of your application code.
Client-server architecture where the driver communicates with OJP server, which manages actual database connections. Decouples applications from direct database access.
Simply replace your database driver with OJP driver and update the JDBC URL. No code changes, no refactoring, no risk.
Implements the standard JDBC API. Your applications work exactly as before, but with enhanced capabilities and protection.
The Java-native Layer 7 proxy server that standardises and controls database access
Built on HikariCP, the production-proven Java connection pool. Server-side pooling means your database sees a controlled, predictable number of connections regardless of application scaling.
Backpressure mechanisms prevent overwhelming the database. Circuit breakers automatically protect against cascading failures. Slow query segregation keeps your system responsive.
Separates connection pooling concerns from your application code. Add or remove application instances without touching database configuration — the server handles all connection governance.
Track every query, monitor connection health, and surface operational issues. Built-in observability gives you real-time insights into your database layer.
Full distributed transaction capabilities. Coordinate transactions across multiple resources with confidence and reliability.
Deploy as Docker container, Kubernetes pod, or standalone JAR. Fits seamlessly into modern infrastructure.
