RE: When you should use NOLOGGING while creating indexes

[Johan [EMAIL PROTECTED] Services]

Advantages:
- Less performance overhead in creating the indexes

Disadvantages:
- Unrecoverable. Ie. If the Database is not shutdown normally after the
creation of the indexes (SHUTDOWN ABORT or crash), you'll have to recreate
those indexes.

Also look at:
- Creating an index in using parallel servers (multiple instances) (I think
this can be done - MAYBE SOMEBODY CAN COMMENT)
- Analyzing your tables and indexes regularly ie. "ANALYSE INDEX <name>
[COMPUTE|ESTIMATE] STATISTICS ...."
