Although I only have experience with the HA configurations, I would have to agree. We've found the ODA patching process, for instance, to be far more fragile and failure-prone than a normal cluster... I'm not joking when I say that we've been opening a SR for a new and improved patching failure every single quarter.

The most recent example being that Oracle forgot to mention in the release notes that the 18.7 update requires a full outage of the cluster stack (due to the disabling of HAIP). After which it took them a couple of weeks to figure out why our patching resulted in unexpected downtime.

Given that Oracle controls both the hardware and software, I would have expected the patching process to be relatively bulletproof. Unfortunately I'm not sure they could have missed the mark further if they tried.

> Your experience shows us the exact opposite - reducing the number of vendors on the stack, actually, doesn’t increase the quality. The reason might be the diffusion of responsibility ( ) within a monolithic organization, where each actor relies on the others to take the responsibility for the final result. An open system consisted of components (hardware, software, OS…) produced by multiple vendors might have created the tension for each of them to test better.
