People don’t get Oracle because they want to get stuck with a super expensive (and still only ok), or super insanely expensive (and maybe sweet) support contract. They get it because they usually don’t know about these things, are trying to do something and BLAM they get hooked.

Many people don’t even realize how long it can take to get a real issue fixed even with a super sweet support contract. For instance, I once was a wet behind the ears Oracle DBA, and when creating a schema i dumbly used a feature in the documentation without checking to see how long it had been released. Unfortunately, it had been released about 6 months before, as I found out later.

It took 6 months for them to figure out that it was the cause of our sporadic ORA600 errors (aka core dumps), by which point we’d already migrated to MySQL for many of the workloads because the database was having at best 95% reliability because of it.

Once we migrated the table off with the feature, somehow our problems ceased, but that was still well before they told us what was going on.
