My company is still dealing with a (thankfully) failed move to oracle. Some hotshot (who is long gone now) sold them on the idea and our DB tables/columns names are still all over the place b/c of oracles limits on name lengths. All new (and really old) tables are full length but around when we thought we were going to move all the table/column names are nearly unreadable... We also have a couple hundred thousand dollar boat anchors (read: oracle servers) because apparently they aren't worth shit if you don't run oracle on then and stripping them for parts is almost a zero-sum game. Also Oracle told us they will try to sell them for us (because they won't just buy them bacl) but they have ZERO incentive to do so when they can swindle some other corporation out of more money by selling new servers. We are now in the middle of switching over to MariaDB and I can't wait to leave Oracle behind.
