• With OUI, you can create configurations that use Automatic Storage Management.
• You can install and configure the Enterprise Manager (EM) framework. Oracle Enterprise Manager Database Control is installed in the same Oracle home as the database and is configured to run on a stand-alone OC4J instance. You have to perform a separate installation to get EM central management capabilities.
• if you choose to use Oracle Enterprise Manager Database Control, you can optionally configure the database to use the Oracle-recommended default backup strategy.
• If you choose to use Oracle Enterprise Manager Database Control during the installation, you can configure Enterprise Manager to send e-mail alerts to an e-mail address that you specify. These alerts can include issues such as disk space reaching a critical limit or a database shutting down unexpectedly.
• The Oracle Database 10g installation supports RAC features, particularly the installation of Cluster Ready Services (CRS)
• Oracle homes can be cloned by using the Enterprise Configuration Management tool. This tool enables users to create clone requests and then schedule and process them. This tool is available via EM Grid Control.
