So this post is long overdue, but the final nail has been driven into the Oracle coffin. Oracle is nothing more than a collection of legacy technology acquisitions, the latest acquisitions aren't really integrated or extended, because there is nothing to integrate or extend into. Its a hodgepodge.
Oracle still doesn't really embrace cloud, it spends 10 to 12 billion a year in stock buy backs, while the real cloud providers invest in cloud infrastructure. That should tell you everything you need to know about Oracles cloud future. Its a cold dark cloud, with no future.
But here is the killer. Oracle has been the dominant player in the relational database market. To the tune of tens of billions a year (in support revenue alone). Good old MH has killed that revenue stream by outsourcing brains and replacing them with cheap labor. It has reached a tipping point. support.oracle.com is now completely broken. It was always sort of broken, with escalations required to the duty manager to get anything done. Now its beyond broken.
The support documentation for Oracle linux on 12c and 18c now has information cut and pasted from Oracle Solaris / Unix from Oracle 10g on how to configure. The last update was from a country with the initials "IN" ... a whole slew of backlogged documenation in Oracle support has been updated quickly and efficiently by this country. It is now completely useless.
When customers call in for support and escalate to a new support engineer, he will forward the broken support documentation to the customer. Worse he may actually start making recommendations to the customer based off the document. Those that can fix the problem have left the company (laid off). Its just a matter of time before the customer stops paying support. First a few then many, then all.
