How Would You Check That A Given Index Is Consistent And Has No Corruption? If Corruption Occurred On A Database What Would Your Process Be?
Answer»
Index (ALONG with database and table) consistency can be verified with oncheck -CDI database_name:table_name. Preferably with the instance put in quiescent mode.
If just the index is CORRUPTED (and not fixable by oncheck), an OPTION will be to recreate the index.
