You can elect to use the same password for all four accounts. Use a password that
meets the complexity requirements of your organization’s security policy but is fairly easy
to remember. After you have finished entering passwords, click Next to go to Step 6: Storage
Options.
Step 6: Storage Options
Figure 6-13 shows the screen for Step 6: Storage Options. Here you select a storage method
for database files. Most databases use traditional file systems for file storage. Automatic
Storage Management (ASM) is an advanced Oracle technology for disk management—it
replaces traditional volume managers and is most useful in high-end systems with hundreds
or thousands of disks. More information on ASM can be found in the references
listed at the end of this chapter. It is also possible to use raw devices to gain a performance
advantage; this was a popular strategy at one time but is no longer in favor because it
introduces complexity and increases the chances that database administrators will make
mistakes with catastrophic consequences.
