2 Log In to the System with Administrator Privileges

Log on as a member of the Administrators group to the computer on which to install Oracle components. If you are installing on a Primary Domain Controller (PDC) or a Backup Domain Controller (BDC), log on as a member of the Domain Administrators group.

3 Check the Hardware Requirements

The following hardware components are required for Oracle Database:

Table 1 Hardware Requirements
Requirement Minimum Value
Physical memory (RAM) 256 MB minimum, 512 MB recommended
Virtual memory Double the amount of RAM
Disk space Basic Installation Type total: 2.04 GB
Advanced Installation Types total: 1.94 GB
See Table 2 for details.
Video adapter 256 colors
Processor 550 MHz minimum

3.1 Hard Disk Space Requirements

Table 2 lists the space requirements for NTFS. The starter database requires 1.03 GB of disk space. The figures in this table include the starter database. FAT32 space requirements are slightly larger.

Table 2 Disk Space Requirements for NTFS
Installation Type TEMP Space C:Program FilesOracle Oracle Home Datafiles * Total
Basic Installation 125 MB 3.1 MB 905 MB 1.03 GB 2.04 GB
Advanced Installation: Enterprise Edition 125 MB 3.1 MB 905 MB ** 950 MB ** 1.94 GB **
Advanced Installation: Standard Edition 125 MB 3.1 MB 905 MB ** 950 MB ** 1.94 GB **
Advanced Installation: Personal Edition 125 MB 3.1 MB 905 MB ** 950 MB ** 1.94 GB **

* Refers to the contents of the admin, flash_recovery_area, and oradata directories in the ORACLE_BASE directory.
** This size can be higher depending on the installation options selected, such as languages or additional components. If you choose to install Oracle Database with automated backups enabled, include at least 2 GB extra for datafile disk space.

See Also:

“About NTFS File System and Windows Registry Permissions” in Oracle Database Platform Guide for Microsoft Windows (32-Bit)

To ensure that the system meets these requirements, follow these steps:

  1. Determine the physical RAM size. For a computer using Windows 2003, for example, open System in the Windows Control Panel and select the General tab. If the size of the physical RAM installed in the system is less than the required size, then you must install more memory before continuing.
  2. Determine the size of the configured virtual memory (also known as paging file size). For a computer using Windows 2003, for example, open System in the Control Panel, select the Advanced tab, and click Settings in the Performance section. Then select the Advanced tab. The virtual memory is listed in the Virtual Memory section.
    If necessary, see your operating system documentation for information about how to configure additional virtual memory.
  3. Determine the amount of free disk space on the system. For a computer using Windows 2003, for example, open My Computer, right-click the drive where the Oracle software is to be installed, and choose Properties.
  4. Determine the amount of disk space available in the temp directory. This is equivalent to the total amount of free disk space, minus what will be needed for the Oracle software to be installed.
    If there is less than 125 MB of disk space available in the temp directory, then first delete all unnecessary files. If the temp disk space is still less than 125 MB, then set the TEMP or TMP environment variable to point to a different hard drive. For a computer using Windows 2003, for example, open System in the Control Panel, select the Advanced tab, and click Environment Variables.

4 Check the Software Requirements

5 Install the Oracle Database Software

To install the Oracle Database software:

  1. If you are installing Oracle Database on a multihomed computer or a computer that uses multiple aliases, use the System in the Control Panel to create the ORACLE_HOSTNAME system environment variable. Set this variable to point to the host name of the computer on which you are installing Oracle Database.
  2. Insert Oracle Database installation media and navigate to the database directory. Alternatively, navigate to the directory where you downloaded or copied the installation files.
    Use the same installation media to install Oracle Database on all supported Windows platforms.
  3. Double-click setup.exe to start Oracle Universal Installer.
  4. In the Welcome window, select either Basic Installation or Advanced Installation, and then answer the prompts as needed.

    See Also:

    Chapter 1 in Oracle Database Installation Guide for Microsoft Windows (32-Bit) for more information on the Basic and Advanced installation methods

    The subsequent windows that appear, which are listed in Table 4, depend on the installation method you have chosen. The order in which the windows appear depends on the options you select.

  5. Follow these guidelines to complete the installation:
    • Do not install Oracle Database 10g release 2 (10.2) software into an existing Oracle home that contains Oracle9i or earlier software.
    • If you install Oracle Database 10g release 2 (10.2) in an Oracle home directory that already contains Oracle Database 10g release 2 (10.2) client software, the listener is not created. To create the listener, install and run Oracle Net Configuration Assistant after the installation. If the Administrator client is installed before Oracle Database, Oracle Net Configuration Assistant is already installed.
    • Follow the instructions displayed in the Oracle Universal Installer windows. If you need additional information, click Help.
    • When prompted for a password, follow these guidelines:
      Make the password be between 4 and 30 characters long.
      Use the database character set for the password’s characters, which can include the underscore (_), dollar ($), and pound sign (#) characters.
      Do not start passwords with a numeral.
      Do not use a user name for a password.
      Do no use Oracle reserved words for the password.
      Do not use change_on_install for the SYS account password.
      Do not use manager for the SYSTEM account password.
      Do not use sysman for the SYSMAN account password.
      Do not use dbsnmp for the DBSNMP account password.
      If you choose to use the same password for all the accounts, do not use change_on_install, manager, sysman, or dbsnmp as a password.
      Have the password include at least 1 alphabetic, 1 numeric, and 1 punctuation mark character
      Do not use simple or obvious words, such as welcome, account, database, and user for the password.


      You must remember the passwords that you specify.

    • Do not modify the Java Runtime Environment (JRE) except by using a patch provided by Oracle Support Services. Oracle Universal Installer automatically installs the Oracle-supplied version of the JRE. This version is required to run Oracle Universal Installer and several Oracle assistants.
    • If you encounter errors while installing or linking the software, see Appendix G in Oracle Database Installation Guide for Microsoft Windows (32-Bit) for information about troubleshooting.
    • If you chose an installation type that runs Database Configuration Assistant and Oracle Net Configuration Assistant in interactive mode, you must provide detailed information about configuring your database and network.
      If you need assistance when using the Database Configuration Assistant or Oracle Net Configuration Assistant in interactive mode, click Help on any window.


      If you chose a default installation, Database Configuration Assistant and Oracle Net Configuration Assistant run non-interactively.

  6. When the configuration tools finish, click Exit, then click Yes to exit from Oracle Universal Installer.
  7. When Oracle Enterprise Manager Database Control opens a Web browser, enter the username and password you created during the installation.
    You can log in as SYS, SYSTEM, or SYSMAN. If you log in as SYS, then you must connect AS SYSDBA. Enter the password you specified for the account during installation.
  8. Optionally, delete the OraInstalldate_time directory if you want to remove the temporary files that were created during the installation process. The OraInstalldate_time directory holds about 45 MB of files. This directory is created in the location set by the TEMP environment variable setting.
    Restarting your computer also removes the OraInstalldate_time directory.
  9. See Chapter 4 in Oracle Database Installation Guide for Microsoft Windows (32-Bit) for information about postinstallation tasks that you must complete after you have installed Oracle Database.

Manual Oracle Uninstall (Windows and UNIX)

Manual Oracle Uninstall

A number of people have contacted me regarding problems uninstalling Oracle products. The two methods listed below should only be used as a last resort and will remove all Oracle software allowing a reinstall. If you make any mistakes they can be quite destructive so be careful.


In the past I’ve had many problems uninstalling all Oracle products from Windows systems. Here’s my last resort method:

  • Uninstall all Oracle components using the Oracle Universal Installer (OUI).
  • Run regedit.exe and delete the HKEY_LOCAL_MACHINE/SOFTWARE/ORACLE key. This contains registry entires for all Oracle products.
  • Delete any references to Oracle services left behind in the following part of the registry:
    It should be pretty obvious which ones relate to Oracle.
  • Reboot your machine.
  • Delete the “C:Oracle” directory, or whatever directory is your ORACLE_BASE.
  • Delete the “C:Program FilesOracle” directory.
  • Empty the contents of your “c:temp” directory.
  • Empty your recycle bin.

At this point your machine will be as clean of Oracle components as it can be without a complete OS reinstall. Remember, manually editing your registry can be very destructive and force an OS reinstall so only do it as a last resort.


Uninstalling all products from UNIX is a lot more consistent. If you do need to resort to a manual uninstall you should do something like:

  • Uninstall all Oracle components using the Oracle Universal Installer (OUI).
  • Stop any outstanding processes using the appropriate utilities:
    # oemctl stop oms user/password# agentctl stop# lsnrctl stop

    Alternatively you can kill them using the kill -9 pid command as the root user.

  • Delete the files and directories below the $ORACLE_HOME:
    # cd $ORACLE_HOME# rm -Rf *
  • With the exception of the product directory, delete directories below the $ORACLE_BASE.
    # cd $ORACLE_BASE# rm -Rf admin doc jre o*
  • Delete the /etc/oratab file. If using 9iAS delete the /etc/emtab file also.
    # rm /etc/oratab /etc/emtab
