Hi Guys, Recently I appeared in an interview for a position (after a long time), Here are a few questions that got me confused. Pls. give me your feedback regarding the same. 1. What are various ways to create a table in one database from another database ? I would say - Create table as select (over the database link) and Export/Import in Table mode. Any other ? 2. If a table has 30 Uniform Extents (no size specified) then under what circumstances it is good or bad ? Basically - What is the advantage of 30 extents over 1 big large extents and what are the minuses ? 3. What are various scenarios which make RMAN the best backup and recovery tool ? 4. what errors did u hit in your most recent DB Recovery procedure ? Actually I never had to do a DB recovery from online backup so far..Refreshes most of the time...But how to handle such a question ? Thank you very much and Looking forward to hear from you soon. Regards
