4.3 Product-Specific Postinstallation Tasks
Many Oracle products and options must be configured before you use them for the first time.
Before using individual Oracle Database 12c release 2 (12.2) products or options, refer to the appropriate manual in the product documentation library, which is available online at: http://docs.oracle.com.
Refer to the following topics for information about configuring various products and features after installation.
- Configuring Oracle Database Vault
 Oracle Universal Installer (OUI) installs Oracle Database Vault by default when you install the Oracle RAC software, but requires additional configuration steps.
- Configuring Oracle Label Security
 After installation, you must configure Oracle Label Security in a database before you use it.
- Configuring the OraClrAgnt Service for Oracle Database Extensions for .NET
 Oracle Database Extensions (ODE) for .NET depends on a Windows service to operate properly. This service is called the OraClrAgnt service.
- Configuring Oracle XML DB
 Oracle XML DB is a required component of the Oracle Database installation. However, you must manually configure the FTP and HTTP ports for Oracle XML DB.
- Configure Storage for External Tables, Shared Files, or Directory Objects
 If your Oracle RAC database uses files that are external to the database, then the external files must be located on shared storage that is accessible to all nodes.
