Arup Nanda ([email protected]) has been an Oracle DBA since 1993, when the world was slowly turning its attention to a big force to reckon with—Oracle7. But he was not so lucky; he was entrusted with a production Oracle database running Oracle 6. Since then, he has never been out of the Oracle DBA career path—weaving several interesting situations from modeling to performance tuning to backup/recovery and beyond, with lots of gray hairs to document each ORA-600. He has written several articles for publications such as Oracle Magazine and for Oracle Tech Net, he has presented at conferences such as Oracle World and IOUG Live, and he has coauthored four books. In 2003, Oracle chose him as the DBA of the Year. He lives in Danbury, Connecticut, with his wife, Anu, and their son, Anish.
