What's New in Oracle Database 11g Release 2 (11.2)

This section describes new features that are documented in this guide and provides pointers to additional information.

Oracle Database 11g Release 3 (11.2.0.3) Enhancements

Starting with Oracle Database 11g Release 2 (11.2.0.3) you can enter the Proxy Realm information while providing details for downloading software updates. The proxy realm identifies the security database used for authentication. If you do not have a proxy realm, then you do not need to provide an entry for the Proxy Username, Proxy Password, and Proxy Realm fields. It is case-sensitive.

This proxy realm is for software updates download only.

Oracle Database 11g Release 2 (11.2.0.2) New Features

The following new features or enhancements are provided with Oracle Database 11g Release 2 (11.2.0.2):

Enhanced Patch Set Installation

Starting with the release of the 11.2.0.2 patch set for Oracle Database 11g Release 2, Oracle Database patch sets are full installations of the Oracle Database software. Note the following changes with the new patch set packaging:

  • Direct upgrades from previous releases (11.x, 10.x) to the most recent patch set are supported.

  • Out-of-place patch set upgrades, in which you install the patch set into a new, separate Oracle home, are the best practices recommendation. In-place upgrades are supported, but not recommended.

  • New installations consist of installing the most recent patch set, rather than installing a base release and then upgrading to a patch release.

New Software Updates Option

New functionality for software updates is available starting with Oracle Database 11g Release 2 (11.2.0.2). Use the Software Updates feature to dynamically download and apply software updates as part of the Oracle Database installation. You can also download the updates separately using the -downloadUpdates option and later apply them during the installation by providing the location where the updates are present.

In-Place Upgrade of Oracle Database Client

This functionality is available starting with Oracle Database 11g Release 2 (11.2.0.2). Use the In-Place Upgrade feature of Oracle Database Client to upgrade an existing Oracle Database Client 11g Release 2 (11.2) version with the latest Oracle Database Client version.

Oracle Database 11g Release 2 (11.2.0.1) New Features

The following new features or enhancements are provided with Oracle Database 11g Release 2 (11.2.0.1):

New Oracle Grid Infrastructure Installation Option

Oracle Database 11g Release 2 introduces the Oracle Grid Infrastructure installation. For single-instance databases, Oracle Grid Infrastructure includes Oracle Automatic Storage Management (Oracle ASM), the listener, and Oracle Restart. Oracle Restart is a new feature that provides the ability to monitor, manage, and automatically restart on failure of the Oracle Database environment including the Oracle Database instance, Oracle Automatic Storage Management instance, and listeners. In a clustered environment, Oracle Grid Infrastructure includes Oracle Clusterware, Oracle ASM, and the listener.

Oracle Grid Infrastructure is only available on 64-bit Windows.

To use Oracle Grid Infrastructure for a standalone server, you must install the Oracle software from the Oracle Grid Infrastructure media before you install the database.

New Desktop and Server Class Options

Oracle Database 11g Release 2 introduces a new option that enables you to specify the type of system on which the database is installed. If you are installing on a laptop or a desktop, then select the Desktop Class option; otherwise, select the Server Class option to install on a server. These options are available on the System Class screen.

There is no difference in the software that is installed after you select any one option but the Desktop Class option installs a single-instance database without the advanced configuration options.

See Also:

"Interactive Installation Types" for more information about the desktop and server class options

Daylight Saving Time Upgrade of Timestamps with Timezone Data Type

When time zone version files are updated due to daylight saving time changes, TIMESTAMP WITH TIMEZONE (TSTZ) data could become stale. In previous releases, database administrators ran the SQL script utltzuv2.sql to detect TSTZ data affected by the time zone version changes and then performed extensive manual procedures to update the TSTZ data.

With this release, TSTZ data is updated transparently with very minimal manual procedures using newly provided DBMS_DST PL/SQL packages. In addition, there is no longer a need for clients to patch their time zone data files.

See Also:

SYSASM Privilege

Starting with 11g Release 2, Oracle ASM administration must be done with the SYSASM privilege. The SYSASM privilege also can be granted using password authentication on the Oracle ASM instance.

You can designate OPERATOR privileges (a subset of the SYSASM privileges, including starting and stopping Oracle ASM) to members of the ORA_OPER for Oracle ASM group.

Using the SYSASM privilege for Oracle ASM administration creates a clearer division of responsibility between Oracle ASM administration and database administration.

See Also:

Oracle Automatic Storage Management Administrator's Guide for more information about the SYSASM privilege, ASMSNMP account, and ORA_DBA operating system group

New Tool to Configure Custom Installation Options

Oracle Universal Installer no longer provides the custom installation option of individual components. Use the chopt tool, a command-line utility that is located in the ORACLE_HOME\bin directory, to configure the database options.

Deinstallation Tool

Use the new deinstallation tool (deinstall) available as an Oracle Technology Network download (before installation) and in the Oracle home directory (after installation) to remove Oracle Database software.

See "About the Deinstallation Tool" for more detailed information

Intelligent Data Placement

The Intelligent Data Placement feature enables you to specify disk regions on Oracle ASM disks to ensure that frequently accessed data is placed on the outermost (hot) tracks which provide higher performance.

See Also:

Oracle Automatic Storage Management Administrator's Guide for more information about Oracle ASM Intelligent Data Placement

Oracle Automatic Storage Management Cluster File System

Oracle Automatic Storage Management Cluster File System (Oracle ACFS) is a new multiplatform, scalable file system, and storage management design that extends Oracle ASM technology, to support data that cannot be stored in Oracle ASM, in both single instance and cluster configurations. Additionally, Oracle ACFS provides snapshot functionality for a point-in-time copy of an Oracle ACFS system.

The software required for Oracle Automatic Storage Management Cluster File System is installed with the Oracle Grid Infrastructure installation.

Data Pump Export and Data Pump Import

Data Pump provides a legacy mode in which you can use original Export and Import parameters when performing Data Pump Export and Import operations.

See Also:

Oracle Database Utilities for more information about Data Pump legacy mode

Use Oracle Restart to Automatically Restart Your Database

Oracle Restart is a new feature included in this release to enhance the availability of Oracle databases in a single-instance environment. If you install Oracle Restart and there is a temporary failure of any part of the Oracle Database software stack, including the database, listener, and Oracle ASM instance, Oracle Restart automatically restarts the failed component. In addition, Oracle Restart starts all these components when the database host computer is restarted. The components are started in the proper order, taking into consideration the dependencies among components.

See Also:

Chapter 4, "Configuring Automatic Restart of an Oracle Database" in the Oracle Database Administrator's Guide for more information about Oracle Restart

New Method of Installing Oracle Automatic Storage Management

In past releases, Oracle ASM was installed as part of the Oracle Database installation. With Oracle Database 11g Release 2 (11.2), Oracle ASM is installed when you install the Oracle Grid Infrastructure components and shares an Oracle home with Oracle Clusterware when installed in a cluster such as with Oracle Real Application Clusters or with Oracle Restart on a single-instance database.

To upgrade an existing Oracle ASM, you must upgrade Oracle ASM by running an Oracle Grid Infrastructure upgrade. If Oracle ASM is not installed and you want to use Oracle ASM as your storage option, then you must complete an Oracle Grid Infrastructure installation before you start Oracle Database installation.

See Also:

"Oracle Grid Infrastructure" for more information about installing the Oracle Grid Infrastructure software

SRVCTL Support for a Single-Instance Database in a Cluster

SRVCTL has been enhanced to support single-instance databases with Oracle Restart on standalone servers and on clusters with Oracle Clusterware. SRVCTL is a command-line interface used to manage Oracle Database processes (database instance, listener, Oracle ASM instance) when using Oracle Restart. With SRVCTL, you can manage the Oracle Restart configuration, see the status of processes managed by Oracle Restart, and start or stop processes such as Oracle Database.

See Also:

Chapter 4, "Configuring Automatic Restart of an Oracle Database" in the Oracle Database Administrator's Guide for more information about SRVCTL commands

Deprecated in Oracle Database 11g Release 2 (11.2)

The following are not supported or available with Oracle Database 11g Release 2:

  • Installing data files directly on raw devices is no longer available during installation with Oracle Universal Installer or Database Configuration Assistant. You must use a file system or Oracle ASM.

  • Custom installation option

  • Windows Server 2000

  • Oracle Ultra Search

Desupported in Oracle Database 11g Release 2 (11.2)

The following feature is no longer supported with Oracle Database 11g Release 2 (11.2):

The -cleanupOBase flag of the deinstallation tool is desupported. There is no replacement for this flag.
