RE: Database Verification

We had a corrupt index block which caused an ORA-600 which was not noticed and eventually brought down the database. We do lots of checks now. (d) All of the above.

(d) All of the above

i) Export to /dev/null will go through all the fields of all the tables, all the rows, but will not scan indexes
ii) Dbverify will scan for block corruptions but not logical corruptions. iii) Analyze will check for table-index logical corruption.

Practically, you could just do an export to /dev/null and make sure the table data is correct. Index can be rebuilt, so it's not as important.
