2 Installing Oracle Database on UNIX

This chapter includes the following topics:

• Section 2.1, "Performing Prerequisite Tasks for Installing Oracle Database"

• Section 2.2, "Installing Oracle Database"

If you are upgrading to Release 5.0.1, see Chapter 7. For database tier system requirements, see the Oracle Database 11g Release 2 (11.2) Installation Guide for your operating system.

Critical Patch Updates See Section 1.8, "Applying Oracle Critical Patch Updates."

2.1 Performing Prerequisite Tasks for Installing Oracle Database

To ensure that your platform meets the minimum requirements for installing Oracle Database, you must perform the following preparatory tasks:

• Create Owners, Groups, and Mount Points

• Configure Kernel Resources and Adjust Operating System Environment

• Install Latest Operating System Patches

2.1.1 Create Owners, Groups, and Mount Points

To create the software owner, required groups, and mount points:

1. Create the software owner and groups:

   • Create a UNIX user to own the Oracle software. Typically, the user name is oracle.

   • Create two groups: one is the Oracle Inventory group; the other is the operating system DBA group. Typically, the group names are oinstall and dba, respectively.

2. Create mount points owned by the oracle user:

   • Create a software mount point of at least 10 GB.

   • Create mount points to hold the database files, control files, and log files, respectively.

3. Test permissions. Ensure that the oracle user can write to the new mount points and all subdirectories.

2.1.2 Configure Kernel Resources and Adjust Operating System Environment

The performance of Oracle Database relies on proper tuning of operating system parameters. In addition, if you are creating several Oracle instances, you might have to increase the amount of shared memory and semaphores on the system by setting kernel parameters.

For details, see the "Configure Kernel Parameters" section of the Oracle Database 11g Release 2 Installation Guide for your operating system.

2.1.3 Install Latest Operating System Patches

Download and install the latest operating system patches required for Oracle, if necessary. Review the latest platform-specific install bulletins for Oracle Database 11.2.0.4.

2.2 Installing Oracle Database

This section includes the following topics:

• Install Oracle Database 11.2.0.4 Enterprise Edition

• Install Oracle Database Examples

2.2.1 Install Oracle Database 11.2.0.4 Enterprise Edition

To install Oracle Database 11.2.0.4:

1. Locate the Oracle Database software in the staging area on the database server where you downloaded it; see Section 1.4, "Downloading and Extracting the Software."

   It is shipped as patch 13390677. This patch contains the entire Oracle Database product.

2. Install Oracle Database 11.2.0.4. For instructions see the patch readme file and Oracle Database 11g Release 2 (11.2) Installation Guide for your operating system at http://www.oracle.com/pls/db112/portal.portal_db?selected=11&frame=

3. Choose to install the Enterprise Edition.

2.2.2 Install Oracle Database Examples

Oracle Database Examples includes the following items:

• Oracle JDBC Development Drivers (required)

• Oracle Database Examples (required)

• Oracle Product Demonstrations (optional)

Note:

You do not need to install any of the sample schemas. They are not required for either Oracle Clinical or Oracle Thesaurus Management System. You can add them later if you change your mind.

To install Oracle Database Examples:

1. Extract p13390677_112040_platform_6of7.zip in the examples directory.

2. Start Oracle Universal Installer from the examples directory and install Oracle Database Examples.

3. Accept all the default values during the installation.

For more information about installing software and various Oracle product demonstrations from the Oracle Database Examples media, see the Oracle Database Examples Installation Guide at http://docs.oracle.com/cd/E11882_01/install.112/e24501.pdf.
