File Locations That Ensure Safe Recovery
The AI files, together with the most recent database backup, contain the same information as the DB files. If you lose the disk containing the DB and BI files, you can use the AI files and database backup to reconstruct the database. For this reason, you should place the AI files on a different disk from the one that contains the DB and BI files.
Figure 8–2 shows sample locations for each of the DB, BI, AI, and event log files.
