I see this phrase repeated over and over: nobody got fired for chosing Oracle, ibm, or Microsoft. I wonder: did anyone got fired for chosing Postgres, Linux, or even new and risky stuff like Mongodb or nodejs? And being told at their exit interview "you should've decided to use Oracle"? I guess tech people are fired for lack of talent in hustling company politics much often than they are for chosing a technology.
Now, your Oracle-hosted application might go down for two days as well, but then people would shrug and say "sometimes this happens."
To be fair to Oracle, though, it does seem to happen less often.
