Index state unusable

by Guest
The index is left in an Index Unusable state if it violates a UNIQUE constraint. They way I read it, the same applies to PRIMARY KEY constraints though the wording is a little ambiguous.

Oracle indexes can go into a UNUSABLE state after maintenance operation on the table or if the index is marked as 'unusable' with an ALTER INDEX command. A direct path load against a table or partition will also leave its indexes unusable. check select index_name,last_analyzed,status from dba_indexes where index_name='NAME';you can get analyzed data but not when it was unusable i think so and also now you need to rebuild those indexes because already in unusable alter index user1.indx rebuild ; The index is left in an Index Unusable state if it violates a UNIQUE constraint.

The ability to make an index "unusable" and then rebuild it after the bulk operation was added for exactly this reason. The big disadvantage to dropping and recreating indexes is that you have to keep the DDL for recreating the indexes in sync with what is actually wanted.

Cause: An attempt has been made to access an index or index partition that has been marked unusable by a direct load or by a DDL operation. Action: DROP the specified index, or REBUILD the specified index, or REBUILD the unusable index partition. Now, you have to rebuild index(es) according to their type, Global or Local. Remember, when you move a table, the index on the table becomes unusable, but when an index is moved to a different physical location with a rebuild command, the index never becomes unusable, why? This test case was generated on a Oracle 10.2.0.3.0 database. Reference.
