disk faults. We recommend that you run all the databases in ARCHIVELOG mode without considering the RAID architecture. Oracle also recommends regular Oracle backup. Remember, the I/O subsystem consists of many components, including controllers, channels, and disk adapters, and the SCSI adapter-any crash of these components will cause irreparable disk errors to your database. Now let's take a look at the most common RAID architecture of Oracle databas

Instance Now let's look at an example of testing the ttyname
