Taming the Storage Dragon: The Adventures of HoTMaN

HoTMaN (HoT-standby MaNager) is a joint research and development project between MySpace and USC Database Laboratory to design and develop a tool to ensure a 24x7 up-time and ease administration of Terabytes of storage that sits underneath hundreds of database servers. The HoTMaN tool's innovation and uniqueness is that it can, with a few clicks, perform operational tasks that require hundreds of keyboard strokes by "Trusted Trained" experts. With HoTMaN, MySpace can within minutes migrate the relational database(S) of a failed server to a hot-standby. A process that could take over 1 hour and had a high potential for human error is now performed reliably.
