With ODP.NET, Managed and Unmanaged Drivers can be deployed easily to common hosted and third-party cloud environments through Web deploy. All ODP.NET specific settings no longer require any operating system level configuration. These settings can be made in the .NET configuration files. Managed and Unmanaged ODP.NET Drivers now share a unified configuration file format.

The ASM Cluster File System (ACFS) extends Automatic Storage Management (ASM) by providing a robust, modern, general purpose file system for files beyond the Oracle database files. ACFS provides support for files such as Oracle binaries, report files, trace files, alert logs, and other application data files. With the addition of the Oracle ASM Cluster File System, ASM becomes a complete storage management solution for both Oracle database and non-database files. ACFS supports large files with 64-bit file and file system data structure sizes leading to exabyte-capable file and file system capacities. ACFS scales to hundreds of nodes and uses extent-based storage allocation for improved performance. A log-based metadata transaction engine is used for file system integrity and fast recovery. The ACFS on-disk structure supports endian neutral metadata. ACFS file systems can be exported to remote clients through industry standard protocols such as NFS and CIFS.

This enhancements represents two changes. The first extends the default disk failure timeout interval (DISK_REPAIR_TIME) from 3.6 hours to 12 hours. In many environments, 12 hours is better suited for safe guarding against data loss because of multiple disk failures, and at the same time, reducing unnecessary overhead from prematurely dropping a disk during a transient failure. The second enhancement provides a new Disk Group Attribute called CONTENT_HARDCHECK.ENABLED that allows optionally enabling or disabling Hardware Assisted Redundancy Data (HARD) checking in Exatadata environments.

Previously, as a protection against data loss during hardware failure, ASM provided up to two additional redundant copies of a file's extents. Flex Disk Groups now can provide up to five redundant copies, in which one or more of the copies can be split off to provide a near instantaneous replica.

The ASM Dynamic Volume Manager (DVM) is a kernel-loadable device driver that provides a standard device driver interface to clients (for example, ACFS). File systems or other processes can do I/O to this device driver as they would to any other disk device driver on the system. DVM is the primary I/O interface for ACFS to perform I/O and build a file system leveraging ASM as a volume manager. DVM is loaded on ASM start up. The device driver is cluster-aware and communicates with ASM for extent map information, extent rebalancing, and I/O failures.

Disk drives have higher transfer rates and bytes per track on the outer tracks. This makes it preferable to keep the hotter data closer to the edge of the disk; that is, the lower numbered blocks. This feature enables ASM to identify higher performance disk regions. Most frequently accessed ASM files can be marked to be moved into the hot region and take advantage of higher I/O performance (for example, hot tablespaces and indices) and able to better meet the application I/O demand. This feature is only applicable when whole physical disks are presented to ASM versus local unit numbers (LUN).

An Oracle Database client is no longer required to provide a wallet to hold well-known CA root certificates if they are available in the local system. The Oracle Database wallet search order determines the location (Windows (Microsoft Certificate Store) or Linux) of these certificates in the local system. Transport Layer Security (TLS) requires either one-way authentication or two-way authentication. In one-way TLS authentication, which is commonly used for HTTPS connections, you will no longer need to install and configure a client wallet to hold the server's CA certificate as long as it is already available in the local system. If the server's CA certificate is not installed in the local systems, client wallet is still required. Starting in this release, you no longer need to install and configure a wallet to hold a well-known root certificate if it is already available in the local system.

Database Overall → Pluggable Databases
Each pluggable database (PDB) now can have its own keystore, instead of there being only one keystore for the entire container database (CDB). Each PDB keystore can have its own password in addition to having its own master encryption key. The advantage of this feature is that it enables independent key management operations to be performed by each tenant (PDB) in a multitenant environment rather than having to share a keystore at the CDB root level. This feature benefits both multitenant and non-multitenant environments because it provides parameters to facilitate the configuration of the keystore location and the keystore type, eliminating the need for editing the sqlnet.ora file. This feature continues to support existing behavior where PDBs share a single keystore with the container database (CDB). This feature further allows some PDBs to share the keystore with the container database (CDB) and some PDBs to have their own keystores.

This enhancement applies to master encryption keys that are used in software keystores only, not hardware keystores. It can be used in non-multitenant, standalone environments and in multitenant environments.

TABLESPACE_ENCRYPTION_DEFAULT_ALGORITHM applies to both offline and online tablespace encryption operations.
