Chapter 4: <strong>Oracle</strong> Database Design<br />
Control files The <strong>Oracle</strong> database, in this solution, has two control files, each stored in different<br />
ASM diskgroups.<br />
Redo logs All database changes are written to the redo logs (unless logging is explicitly turned<br />
off) <strong>and</strong> are there<strong>for</strong>e very write-intensive. To protect against a failure involving the<br />
redo log, the <strong>Oracle</strong> database was created with multiplexed redo logs so that copies<br />
of the redo log can be maintained on different disks.<br />
Archive log mode was enabled, which automatically created database-generated<br />
offline archived copies of online redo log files. Archive log mode enables online<br />
backups <strong>and</strong> media recovery.<br />
Note<br />
<strong>Oracle</strong> recommends that archive logging is enabled.<br />
