Planning an Oracle Database Installation

1. Understand how the installation fits into the

overall technical architecture of an organization.

2. Review (and update) capacity plans.

3. Choose database software (required version andoptions).

4. Ensure that system requirements are met for all

chosen elements.

5. Plan configuration parameters to be set before,

during, and after the installation.

6. Plan security and access.

7. Plan backup and recovery mechanisms.



Planning and Executing DBA Projects:

Quiz

As a DBA:

1. You must be able to install and configuremany different types of databases.

2. You should be aware of upcoming projects.

3. You do not need to understand the businessrequirements for a database.

4. You should always compare your plannedand actual results.

5. You do not need to plan for databaserecovery, because you have anuninterrupted power supply.

System Requirements

Memory requirements: 1 GB for the instance with Database Control

Disk space requirements:

1.5 GB of swap space

400 MB of disk space in the /tmp directory Between 1.5 GB and 3.5 GB for the Oracle software

1.2 GB for the preconfigured database (optional)

2.4 GB for the flash recovery

area (optional)

Operating system: Seedocumentation.



Checking the System Requirements

Adequate temporary space

64-bit versus 32-bit issues

Checks for the correct operating system (OS)

OS patch level System packages

System and kernel

parameters

X Server permissions Sufficient swapping

Nonempty ORACLE_HOME



Optimal Flexible Architecture (OFA)

OFA is designed to:

Organize large amounts of software

Facilitate routine administrative tasks

Facilitate switching between multiple Oracle

databases Manage and administer database growth

adequately

Help eliminate fragmentation of free space



Using Optimal Flexible Architecture

Naming mount points:

/u01

/disk01

Naming directories: /u01/app/oracle

/u01/app/applmgr

Naming files:

Control files:control

n

.ctl Redo log files: redon.log

Data files: tn.dbf

Setting Environment Variables

ORACLE_BASE: The base of the Oracle directorystructure for OFA

ORACLE_HOME: The directory containing the Oraclesoftware

ORACLE_SID: The initial instance name (ORCL bydefault)

NLS_LANG: The language, territory, and clientcharacter set settings

Installation Option: Silent Mode

To install and configure Oracle products with OUI in

silent mode, perform the following steps:

1. Create the oraInst.loc file, if it does not alreadyexist.

2. Prepare a response file based on file templatesthat are delivered with the Oracle software.

3. Record a response file:.runInstaller record -destinationFile

4. Run OUI in silent or suppressed mode.

5. If required, run NetCA and DBCA in silent mode.



Summary

In this lesson, you should have learned how to:

Describe your role as a DBA, and explain tasks

and tools

Plan your installation, starting with the appropriatedocumentation

Perform preinstallation tasks, such as checking

system requirements

Install software by using OUI

Create a database with the OUI configuration
