Actions Performed by the Utilities
Install
Installation is the process of choosing products from a release or stage area and
deploying them in the target directory. There are four modes of installation, which are
explained in the section "Modes of Installation" on page 1-4.
De-install
De-installation is the process of removing an installed product from the installation
area. A de-installation can be cancelled, resumed or rolled back. It can be executed
either interactively or silently.
Cloning
Cloning is the process of copying an existing installation to a different location while
preserving its configuration. You can install multiple copies of the Oracle product
easily on different computers using cloning. During cloning, Oracle Universal Installer
is invoked in clone mode to adapt the home to the target environment. Oracle
Universal Installer in clone mode will replay all the actions that have been executed to
originally install the Oracle home. The difference between installation and cloning is
that, during cloning, Oracle Universal Installer will run the actions in the clone mode.
Each action will decide how to behave during clone time. For more information on
cloning refer to Chapter 7, "Oracle Software Cloning Using Oracle Universal Installer".
Patching
During Patching, a small collection of files are copied over an existing installation to
fix certain bugs. OPatch is an Oracle supplied utility that facilitates Oracle software
patching. For more information on OPatch, refer to Chapter 8, "Oracle Software
Patching Using OPatch".
Upgrades and Patchsets
Oracle Universal Installer enables you to upgrade a product from one version to
another version. An upgrade is a major product enhancement that often requires
installation of the upgraded software. For example, you may want to convert your
Oracle9i Database to Oracle 10gR2 (10.2) Database, which is called an upgrade.
A group of patches form a patchset. For example, You may want to convert your
Oracle 10gR1 (10.1) Database from version 10.1.1 to version 10.1.2, then it is called
applying a patchset.
Adding Nodes
An Oracle home may be installed on multiple nodes in a cluster. You can extend the
cluster for a particular Oracle home using the -addNode flag of Oracle Universal
Installer. More than one node may be added to the Oracle home. The Oracle Universal
Installer with the -addNode flag is always run on the local node and not on the
node(s) to be added. You can add nodes to an Oracle Clusterware node or a Real
Application Clusters node depending upon whether the node addition is being
performed at the Oracle Clusterware layer or the Real Application Clusters database
layer. For more information on adding nodes, refer to section "Adding Additional
Nodes to the Cluster for Mass Deployment" on page 6-19.
