An induced outage by me Non-mission critical database running an enterprise portal. I am reorganising the online redo logs. ALTER DATABASE CREATE LOGFILE ALTER DATABASE DROP LOGFILE rm redo01.dbf running it in a cycle. Oops. I did an rm redo04.dbf that was ACTIVE. (Fortunately, not CURRENT). Wasn't confident that a CLEAR LOGFILE would fix it so did a quick SHUTDOWN and STARTUP. The shutdown/startup wasn't noticed but I did send an email to the Portal manager that I had restarted the database.
