Oracle 9i on Solaris Case Study (A Deep Dive Retro)
In the early 2000s, database outages were not masked by load balancers, auto-scaling groups, or managed cloud services. If an Oracle database went down on Solaris, the business felt it immediately.
There was no RAC, no ASM, no cloud snapshots. Every failure meant manual diagnosis, filesystem checks, kernel tuning, and long recovery windows. Downtime translated directly into revenue loss and SLA breaches.
This case study revisits a real-world Oracle 9i on Solaris production environment, breaking down architecture decisions, tuning practices, failures, and the lessons modern DBAs can still apply today.
