  • 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 for administering Oracle Real Application Clusters (RAC) by introducing the SYSRAC administrative privilege that does not require the SYSDBA administrative privilege. 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.

New Features for Oracle Automatic Storage Management 12c Release 2 (12.2)

  • Automatic Configuration of Oracle ASM Filter Driver

    Starting with Oracle Database 12c Release 2 (12.2), you can enable and automate the configuration of Oracle ASM Filter Driver (Oracle ASMFD) with a check box during the Oracle Grid Infrastructure installation.

  • Oracle ACFS Snapshot-Based Replication

    The Oracle Automatic Storage Management Cluster File System (Oracle ACFS) snapshot-based replication feature uses Oracle ACFS snapshot technology to transfer the differences between successive snapshots to the standby file system using standard ssh transport protocol. Oracle ACFS Snapshot-based replication is more efficient with higher performance, lower overhead, and ease of management.

    See Also:

    Oracle Automatic Storage Management Administrator's Guide

  • Oracle ACFS Compression

    Oracle ACFS provides file system compression functionality, reducing storage requirement, and resulting in lower costs. Oracle ACFS compression is managed using the new acfsutil compress commands and updates to the acfsutil info command.

    See Also:

    Oracle Automatic Storage Management Administrator's Guide

  • Oracle ACFS Defragger

    Databases that share storage with snapshots or with the base of the file system can become fragmented under active online transaction processing (OLTP) workloads. This fragmentation can cause the location of the data in the volume to be discontiguous for sequential scans. Oracle ACFS automatically defragments these files in the background.

    Oracle Automatic Storage Management Administrator's Guide

  • Oracle ACFS Support for 4K Sectors

    Oracle ACFS supports I/O requests in multiples of 4K logical sector sizes as well as continued support for 512-byte logical sector size I/O requests. The i4096 option is provided with the acfsformat command on Microsoft Windows and the mkfs command in Linux and Oracle Solaris environments.

New Features

Deprecated Features

The following features are deprecated in this release, and may be desupported in a future release:

  • Deinstallation Tool Integrated with Installation Media

  • Deprecation of -cleanupOBase

    The -cleanupOBase flag of the deinstallation tool is deprecated in this release. There is no replacement for this flag.

  • Windows NTS Authentication Using the NTLM Protocol

    The NTS authentication adapter no longer supports the use of the NT LAN Manager (NTLM) protocol to authenticate Windows domain users. Thus, the NTS adapter cannot be used to authenticate users in old Windows NT domains or domains with old Windows NT domain controllers. However, local connections and Oracle Database services running as a Windows Local User continues to be authenticated using NTLM. A new client-side sqlnet.ora boolean parameter, no_ntlm (default value is FALSE) enables you to control if NTLM can be used in NTS authentication. When the parameter is set to TRUE, NTLM cannot be used in NTS authentication.
