Flashback to 2001: This IT project's development database suddenly crashes and burns, and no one can log in, reports a pilot fish on the team.
"We kept getting errors about insufficient privileges," fish says. "I went over to the project's senior DBA to ask him to look into it.
"He logged in as the SYS superuser -- the highest level of database permissions -- and discovered that all permissions to the data dictionary had evaporated."
Fish has a large Oracle data dictionary poster that arrived sometime before in a big, heavy cardboard mailing tube. He grabs the tube and walks over to the junior DBA's desk.
What did you do to the development database? fish asks.
