Oracle Database 11g Release 2 (11.2.0.2) New Features

The following is a list of new features or enhancements provided with Oracle Database

11g Release 2 (11.2.0.2):

■ Enhanced Patch Set Installation

■ New Software Updates Option

■ Oracle Automatic Storage Management Cluster File System

■ In-Place Upgrade of Oracle Database Client

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 are 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

This functionality 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.

Oracle Automatic Storage Management Cluster File System

Oracle Automatic Storage Management Cluster File System (Oracle ACFS) is a new

multi-platform, scalable file system, and storage management design that extends

Oracle ASM technology to support data which 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 grid infrastructure installation.

Server"

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 gets installed after you select any one option

but the Desktop Class option installs a single instance database without the advanced

configuration options.

Daylight Saving Time Upgrade of Timestamp 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 had to perform extensive manual

procedures to update the TSTZ data.

With this release, TSTZ data is updated transparently with 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.

SYSASM Privilege

Starting with Oracle Database 11g Release 2 (11.2), 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

OSOPER

for an Oracle ASM

group.

Using the

SYSASM

privilege for ASM administration creates a clear division of

responsibility between ASM administration and database administration. It also

provides the optional capability to prevent different databases using the same storage

from accidentally overwriting each other's files.

Fixup Scripts and Prerequisite Checks

Starting with Oracle Database 11g Release 2 (11.2), the Oracle Universal Installer (OUI)

detects when minimum requirements for an installation are not completed, and creates

scripts, called fixup scripts, to resolve many incomplete system configuration

requirements. If OUI detects an incomplete task, then click the Fix & Check Again

button to generate the fixup script.

See Also: "Interactive Installation Types" on page 1-5 for more

information about the desktop and server class options

upgrade Timestamp with Time Zone data

how to upgrade the Time Zone file and Timestamp with Time

Zone data

versions of Time Zone files

SYSASM

privilege,

account,

For Oracle Clusterware, you also can have Cluster Verification Utility (CVU) generate

fixup scripts before the installation.

The fixup script is generated during the installation. You are prompted to run the

script as root in a separate terminal session. When you run the script, it sets some

system parameters to Oracle-recommended values, if necessary, and completes other

operating system configuration tasks.

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 Chapter 7, "Removing Oracle Database Software"

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.

Oracle Data Pump Export and Oracle Data Pump Import

Data Pump provides a legacy mode in which you can use original export and import

parameters when performing Oracle Data Pump export and import operations.

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.

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
