Simplified Image based Oracle Grid Infrastructure Installation
Starting with Oracle Grid Infrastructure 12c Release 2 (12.2), the Oracle Grid Infrastructure software is available as an image file for download and installation. You must extract the image software into the directory where you want your Grid home to be located, and then run the
gridSetup.sh
script to start the Oracle Grid Infrastructure installation.For more information, see About Image-Based Oracle Grid Infrastructure Installation
-
Parallel NFS Support in Direct NFS Client
Starting with Oracle Database 12c Release 2 (12.2), Oracle Direct NFS Client supports parallel NFS. Parallel NFS is an NFSv4.1 option that allows direct client access to file servers, enabling scalable distributed storage.
For more information, see About Direct NFS Client Mounts to NFS Storage Devices
-
Direct NFS Dispatcher Support
Starting with Oracle Database 12c Release 2 (12.2), Oracle Direct NFS Client supports adding a dispatcher or I/O slave infrastructure. For very large database deployments running Direct NFS client, this feature facilitates scaling of sockets and TCP connections to multi-path and clustered NFS storage.
For more information, see About Direct NFS Client Mounts to NFS Storage Devices
-
Kerberos Authentication for Direct NFS
Starting with Oracle Database 12c Release 2 (12.2), Oracle Database supports Kerberos implementation with Direct NFS communication. This feature solves the problem of authentication, message integrity, and optional encryption over unsecured networks for data exchanged between Oracle Database and NFS servers using Direct NFS protocols.
For more information, see Creating an oranfstab File for Direct NFS Client
-
Separation of Duty for Administering Oracle Real Application Clusters
Starting with Oracle Database 12c Release 2 (12.2), Oracle Database provides support for separation of duty best practices when administering Oracle Real Application Clusters (Oracle RAC) by introducing the SYSRAC administrative privilege for the clusterware agent. This feature removes the need to use the powerful SYSDBA administrative privilege for Oracle RAC.
SYSRAC, like SYSDG, SYSBACKUP, and SYSKM, helps enforce separation of duties and reduce reliance on the use of SYSDBA on production systems. This administrative privilege is the default mode for connecting to the database by the clusterware agent on behalf of the Oracle RAC utilities such as
srvctl
.For more information, see Extended Oracle Database Groups for Job Role Separation
-
AL32UTF8 As the Default Database Character Set
Starting with Oracle Database 12c Release 2 (12.2), the default database character set of a database created from the General Purpose/Transaction Processing or the Data Warehousing template is Unicode AL32UTF8. Oracle recommends that you use Unicode AL32UTF8 as the database character set.
For more information, see About Character Set Selection During Installation
-
Postinstallation Configuration of Oracle Software using the -executeConfigTools option
Starting with Oracle Database 12c Release 2 (12.2), you can perform postinstallation configuration of Oracle products by running the Oracle Database or Oracle Grid Infrastructure installer with the
-executeConfigTools
option. You can use the same response file created during installation to complete postinstallation configuration.For more information, see Installing and Configuring Oracle Database Using Response Files
Deprecated Features
The following feature is deprecated in this release, and may be desupported in a future release:
-
Deprecation of the
configToolAllCommands
scriptStarting with Oracle Database 12c Release 2 (12.2), the
configToolAllCommands
script is deprecated and is subject to desupport in a future release. TheconfigToolAllCommands
script runs in response file mode to configure Oracle products after installation and uses a separate password response file.To perform postinstallation configuration of Oracle products, you can now run the Oracle Database or Oracle Grid Infrastructure installer with the
-executeConfigTools
option. You can use the same response file created during installation to complete postinstallation configuration.

Root Scripts Automation
Starting with Oracle Database 12c Release 1 (12.1), Oracle Universal Installer provides options to automatically run root configuration scripts required during a grid infrastructure installation. You also have the option to manually run the root configuration scripts.
-
Oracle Flex ASM
Oracle Flex ASM enables an Oracle ASM instance to run on a separate physical server from the database servers. Many Oracle ASM instances can be clustered to support a large number of database clients.
Oracle Database instances can be set up as clients to Oracle Flex ASM where metadata is provided to the database instance by an Oracle Flex ASM instance that may be on a different node than the database instance.
Note that Oracle Flex ASM can apply to a collection of databases, each one a single instance but running in a Flex ASM Cluster.
For more information about Oracle Flex ASM, see:
-
Deinstallation Tool Integrated with Installation Media
Starting with Oracle Database 12c, the deinstallation tool is integrated with the database installation media and is no longer provided on a separate installation media.
For more information, see:
-
Simplified Oracle Label Security Installation
Starting with Oracle Database 12c, Oracle Label Security is installed by default as part of the Oracle Database installation. You can no longer select Oracle Label Security as a custom component during an Enterprise Edition database installation.
For more information, see:
-
Simplified Oracle Database Vault Installation
Starting with Oracle Database 12c, Oracle Database Vault is installed by default as part of the Oracle Database installation. However, you can configure, enable, or disable Oracle Database Vault after the Oracle Database installation, either using Oracle DBCA, or by running SQL statements. For more information, see:
-
Oracle Database Vault Administrator's Guide, "Disabling and Enabling Oracle Database Vault."
-
Oracle Database Vault Administrator's Guide, "Registering Oracle Database Vault with an Oracle Database"
-
-
Unified Database Audit Configuration
Starting with Oracle Database 12c, you can create named audit policies. An audit policy contains a set of audit options, which is stored in the database as an object. The advantage of creating a named audit policy is that it reduces the number of commands that are required to create a database audit policy, and it simplifies the implementation of an audit configuration for security and compliance with conditional auditing.
This new audit policy framework is included with the database installation.

Oracle Enterprise Manager Database Express 12c
Oracle Database 12c introduces Oracle Enterprise Manager Database Express 12c, a web-based management tool built into Oracle Database without any need for special installation or management. Using Oracle Enterprise Manager Database Express, you can perform basic administrative tasks such as user, performance, memory, and space management. You can also view performance and status information about your database.

-
Support for Separation of Database Administration Duties
Oracle Database 12c provides support for separation of database administration duties for Oracle Database by introducing task-specific and least-privileged administrative privileges that do not require the SYSDBA administrative privilege. These new privileges are: SYSBACKUP for backup and recovery, SYSDG for Oracle Data Guard, and SYSKM for encryption key management. For more information, see:
-
Oracle DBCA Support for CDBs and PDBs
Starting with Oracle Database 12c, Oracle Database Configuration Assistant (Oracle DBCA) allows you to create a a multitenant container database (CDB) or a non-CDB. You can create the CDB with zero, one, or more user-created pluggable databases (PDBs).
You can also create a CDB with one PDB during the database installation.
For more information, see:
