RE: Change index from nologging to logging

Yes, it is wrong. The manuals are often technically wrong and sometimes like this one the manuals are just out and out wrong based on the wording.

Hi Hemant,

Thanks for your reply. That seems clear: so the line in the manual stating that "This setting also determines whether subsequent Direct Loader (SQL*Loader) and direct-path INSERT operations against the index are logged or not logged." is just wrong?

Thanks
Charlotte

In the manual (SQL Reference 10g) it says:

Specify whether the creation of the
index will be logged (LOGGING) or not logged (NOLOGGING) in the redo log file.
This setting also determines whether subsequent Direct Loader (SQL*Loader) and direct-path INSERT operations against the index are logged or not logged.
LOGGING is the default.Are you not counting direct load/insert as DML, or do you believe this statement is wrong? I'd like to test it but so busy just now...

Followup August 29, 2008 - 11pm US/Eastern: indexes always, always, always generate redo during any insert, any - any - any insert.

We were talking only about tables.

insert /*+ append */ - since it is done in bulk will MINIZE the redo, but it'll generate redo for the indexes *always* if the index is maintained.
