Prerequisites
• Read Site Guard Administrator’s Guide in the Oracle Enterprise Manager Cloud Control Online Documentation Library for your release of Oracle Enterprise Manager.
• Oracle Data Guard must be installed and configured on the Oracle RDBMS instances at each site, such that one site is Primary and the other site(s) are Standby. See the “Getting Started with Oracle Data Guard” chapter of Oracle Data Guard Concepts and Administration. Make sure that the fast recovery area on all database instances in the Oracle Data Guard configuration are configured with enough space to cover worst case gap in applying archive logs to the standby database(s). This is the db_recovery_file_dest_size system property.
• Optional, but recommended: Install the Application Management Pack for Oracle Utilities Network Management System in Oracle Enterprise Manager. Discover and configure the NMS targets at each site.
