  Install Oracle Database 11g R2 on Linux using Oracle ASM - (OL5) — (17-January-2012)

The article described in this newsletter is a comprehensive guide for 
installing Oracle Database 11g Release 2 (11.2) on the Oracle Linux 5 (OL5)
operating environment using Oracle Automatic Storage Management 
(Oracle ASM) and Oracle Restart.

Oracle ASM provides a virtualization layer between the database and storage so 
that multiple disks can be treated as a single disk group and disks can be 
dynamically added or removed while keeping databases online. The example 
database created in this guide will use Oracle ASM for all physical database 
file storage (data files, control files, online redo log files, Fast Recovery 

In previous releases, Oracle ASM was installed as part of the Oracle Database 
installation. With Oracle Database 11g Release 2, Oracle ASM is part of an 
Oracle Grid Infrastructure installation, either for a cluster, or for a 
standalone server. This guide demonstrates how to create a single instance 
(non-RAC) database using Oracle ASM and therefore will require Oracle Database 
11g Release 2 Grid Infrastructure for a Standalone Server to be installed 
before the Oracle Database software.

Oracle Restart is another component of Oracle Grid Infrastructure for a 
Standalone Server that will be used in this guide.

Starting with Oracle Database 11g Release 2, the dbstart and dbshut scripts 
that were used to automate database startup and shutdown in previous Oracle 
versions are deprecated. Oracle now recommends to configure Oracle Database 
with the Oracle Restart feature to automatically restart the database, the 
listener, Oracle Automatic Storage Management (Oracle ASM), and other Oracle 
components after a hardware or software failure or when the database host 
computer restarts.
