Cephalon.Observability.OracleDependencies adds a supported Oracle Database dependency-health path for Cephalon hosts.

What it owns

• Engine:Observability:DependencyHealth:Oracle configuration binding
• connection-string or discrete host/service-name probe settings for Oracle Database endpoints
• lightweight SELECT 1 FROM DUAL-style health-query execution through Oracle.ManagedDataAccess.Core
• reusable IDependencyHealthContributor integration for Oracle-backed readiness and diagnostics

Main surfaces

• Configuration/OracleDependencyDefinition.cs
• Configuration/OracleDependencyHealthOptions.cs
• Hosting/OracleDependencyHealthServiceCollectionExtensions.cs
• Services/OracleDependencyHealthProbeHostedService.cs

Source structure

How it fits

This package keeps Oracle-specific connection handling out of Cephalon.Engine while still feeding the existing dependency-health contract. Hosts can opt into it when they need managed Oracle readiness to surface through /engine/dependencies, /health/live, /health/ready, and /engine/diagnostics without re-implementing Easy Connect shaping or Oracle query probes per host. When active, it also publishes its probe event ids through the shared runtime diagnostics catalog.
