# Installing Oracle Database 11g - Oracle 11g

The Oracle Universal Installer steps for installing the Oracle Data base 11g release software are similar to the steps for the Oracle 10g release.There are a few changes,however, which we’ll high light when we show the installation steps in this section. You use the run Installer executable to invoke the GUI-based Ora cle Universal Installer.If you’ve down loaded the server soft ware from the Oracle web site,you must first uncompress the down loaded file.This will create a directory named data base, under which you’ll find the run Installer script.Start the installation process by moving to the database directory and typing the following:

$./runInstaller If you’re installing from a DVD, invoke the installer by supplying the full path for the database directory on the DVD:$ /<directory_path>/runInstaller

If you pass the minimal operating system requirements,the Oracle Universal Installer will open.Once the Oracle Uni versal Installer GUI shows up,the following are the steps in the installation process:

1. On the Select Installation Method page,you can select either Basic Inst- allation or Advanced Installation. Select Advanced Installation,and click Next.
2. Select Installation Type.You’re given three choices—Enter prise Edition, Standard Edition,and Custom.Choose Enterprise Edition, and click Next.
3. On the Install Location page,specify the path for the Oracle base and Oracle home locations, which is where the Oracle Uni versal Installer will install the data base files.Click Next.
4. On the Product-Specific Prerequisite Checks page, the Oracle Universal Installer will verify that your environment meets the minimum requi rements for installing the various products you want to install.hese checks include the kernel parameters,swap space requirements,validation of the Oracle base location,and network configuration requirements.It’s a good idea to go ahead and fix any warnings produced by the Oracle Universal Installer at this stage, say by up dating the kernel on a Linux system,although you can get away with not doing so in most cases since the Oracle Universal Installer offers you the choice of continuing despite a warning.Once you pass the requirement checks,click Next.
5. Select Configuration Option.You can choose to create a data base,configure ASM, or just install the Oracle 11g binaries.For the last option, choose Install Software Only, and click Next.
6. You’ll see the Privileged Operating System Groups page next, as shown in Figure This step is new in Oracle Data base 11g.In addition to the sys dba and sysoper privileges you’re familiar with, Oracle now recommends you create the new system privilege called sysasm for enabling the management of ASM. Oracle also recommends you create a new Unix/Linux group now, called osasm, for ASM administrators.

8. On the Summary page,the Oracle Universal Installer summa izes the installation,including the names of all the components it will install. Click Next after reviewing the summary.
9. On the Install page, you’ll see the progress of the installation. Once the installation finishes successfully,exit the Oracle Universal Installer by first clicking Exit and then clic king Yes.

If you choose to create a new starter data base(step 5),the Oracle Universal Installer invokes the Data base Configuration Assistant(DBCA)to create the database.We discuss creating a new data base with the DBCA in the following section.You’ll see the new features we discuss there (such as specifying the automatic memory configuration details) if you choose to create a new data base during installation itself by choosing the Create a Data base option here.by default, Oracle includes the new Secure Configu ration option,which configures the data base with auditing options as well as pass word policy and expiration settings.If you want, you can disable the new enhanced security controls during the installation.

Also,if you choose to create the starter data base during the installation,you’ll get an option to configure the Oracle Configu ration Manager.You’ll need to configure the Oracle Configuration Manager in order to associate the data base configuration infor mation with Oracle Meta Link.You can then link your service requests to Meta Link with your configuration information.Chapter 2 explains more about the Oracle Configuration Manager in the context of the new Support Work bench feature.
