2 Installing Oracle Database on UNIX

This chapter includes:

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

• Section 2.2, "Installing Oracle Database"

If you are upgrading to Release 5.1, see Chapter 7.

For database tier system requirements, see the Oracle Database Installation Guide for your operating system at http://docs.oracle.com/cd/E16655_01/nav/portal_11.htm.

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

Oracle Database 12.1.0.1  includes many new features including multitenancy, which allows you to create one or more pluggable databases (PDBs) contained in a single root or container database (CDB). You can install Oracle Thesaurus Management System on either a pluggable database or a non-CDB database (as in 11g). For more information on multitenancy, see http://docs.oracle.com/database/121/CNCPT/cdbovrvw.htm.

Oracle recommends learning about these new features in Oracle White Paper Plug into the Cloud with Oracle Database 12c at http://www.oracle.com/technetwork/database/plug-into-cloud-wp-12c-1896100.pdf and, for more details, the Oracle® Database New Features Guide 12c Release 1 (12.1) at http://docs.oracle.com/database/121/NEWFT/toc.htm.

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.

4. Ensure that the oinstall group 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 section on configuring kernel parameters in the of the Oracle Database 12c Installation Guide for your operating system available here: http://docs.oracle.com/database/121/nav/portal_11.htm

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 12c Release 1 (12.1.0.1).

2.2 Installing Oracle Database

This section includes:

• Install Oracle Database 12.1.0.1 Enterprise Edition

• Install Oracle Database Examples

2.2.1 Install Oracle Database 12.1.0.1 Enterprise Edition

To install Oracle Database 12.1.0.1:

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."

2. Install Oracle Database 12c Release 1 (12.1.0.1). For instructions see the readme file and the section "Running Oracle Universal Installer" in the Oracle Database Installation Guide for your operating system at http://docs.oracle.com/cd/E16655_01/nav/portal_11.htm.

3. Choose to install the Enterprise Edition.

4. Choose the following database options that are required for Oracle Thesaurus Management System:

   • Oracle XML DB

   • Oracle JVM

   • Oracle InterMedia

   • Oracle Text

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 the zip file containing Oracle Database Examples in the examples directory.

2. Start Oracle Universal Installer from the examples directory.

   ./runInstaller
   

   Or, if the database server has multiple Oracle Homes, then enter:

   ./runInstaller -invPtrLoc ORACLE_HOME/oraInst.loc
   

   For example:

   ./runInstaller -invPtrLoc /u01/app/oracle/product/121010_qa/oraInst.loc
   

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/E16655_01/nav/portal_11.htm.
