About

I'm Yaro, writing here as Uptime Architect — a systems architect who has spent 27 years designing and running mission-critical Oracle databases — RAC clusters, Data Guard standbys, large estates, and cloud migrations.

This blog is a personal project. I write down what actually works in production — how to read an AWR report without drowning, how to test a DR plan before you need it, how to migrate to OCI or Azure without a weekend disaster — mostly so I stop re-learning it, and in case it helps someone else. It's opinionated, vendor-neutral, and verified against real systems.

Topics I write about

• High availability & DR — RAC, Data Guard, RMAN, failover and recovery.
• Performance — AWR/ASH, wait events, SQL and optimizer tuning.
• Cloud & migration — OCI, Azure, Exadata, 23ai/26ai, on-prem to cloud.
• Security & operations — hardening, patching, auditing, automation.
