Chapter 4: Oracle Database Design Chapter 4: Oracle Database Design Overview Introduction to Oracle database design ASM diskgroups This chapter provides guidelines on the Oracle database design used for this validated solution. The design and configuration instructions apply to the specific revision levels of components used during the development of the solution. Before attempting to implement any real-world solution based on this validated scenario, gather the appropriate configuration documentation for the revision levels of the hardware and software components. Version-specific release notes are especially important. The database was built with four distinct ASM diskgroups (+DATA, +FRA, +REDO, and +TEMP). ASM Diskgroup Contents DATA Data and index tablespaces, controlfile FRA Archive logs REDO Online redo log files, controlfile TEMP Temporary tablespace The ASMCMD CLI lists the diskgroups, showing the state of each one.

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