Oracle DBA Question 46
« on: April 20, 2009, 02:21:57 PM »
Question:
After running the ANALYZE INDEX orders cust _idx VALIDATE STRUCTURE command, you query the INDEX _STATS view and discover that there is a high ratio of DEL_LF_ROWS to      
LF_ROWS values for this index.
You decide to reorganize the index to free up the  extra  space,but the space should remain allocated to the ORDERS_CUST _ IDX  index so that it can be reused  by  new entries  into the index.
Which command (s) allows you to perform this task with the minimum impact to any users          who run queries that need to access this index while the index is reorganized?

A .ALTER INDEX REBUILD.
B. ALTER INDEX COALESCE.
C. ALTER INDEX DEALLOCATE.
D. DROP INDEX followed by CREATE INDEX.

Answer :B
