Re: Change index from nologging to logging

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.
