This chapter guides you through the deinstallation and reinstallation process for Oracle9i Application Server (Oracle9iAS). The topics include:
This section guides you through the deinstallation process of Oracle9iAS. This section includes the following topics:
In order to successfully deinstall Oracle9iAS from your host, Oracle recommends deinstalling all secondary (or subsequent) Oracle9iAS installations before you deinstall the primary (or first) installation.
Your primary installation contains the active Oracle9iAS Administration Service. If you deinstall the primary installation and there are other installations of Oracle9iAS on your host, the Oracle Universal Installer requests that you designate one of the remaining Oracle9iAS installations to be the primary installation. The new primary installation will maintain the configuration information for the remaining Oracle9iAS installations on the host.
You must stop all Oracle services and applications before starting the deinstallation process. Refer to the Oracle9i Application Server Administrator's Guide for instructions on starting and stopping the Oracle Enterprise Manager Web site.
Note: Oracle Universal Installer does not permit custom deinstallation of select components or Oracle9iAS instances. Confirm deinstall objectives before launching deinstallation. |
If you are deinstalling an instance of Oracle9iAS Infrastructure, then you must first deinstall the existing installation of Oracle9iAS Metadata Repository using the Oracle Database Configuration Assistant (DBCA).
Using the DBCA to delete a database removes a database's initialization parameter files, instances, optimal flexible architecture, and network configuration. However, the DBCA does not remove datafiles if you placed the files on raw partitions.
To delete a database with the DBCA:
The DBCA Welcome page appears. Click Next.
Based on your system configuration you may see the following screens:
Click OK to complete the deletion of the database and its associated files, or click Cancel to stop the operation.
When you click OK, the DBCA continues the operation and deletes all the associated instances for this database.
The Welcome screen appears. Click Deinstall Products.
The Welcome screen provides information about Oracle Universal Installer.
The installer provides you with two ways to deinstall products:
The Inventory screen appears when you click Deinstall Products on the Welcome screen, or Installed Products on any screen.
The Inventory screen displays all the components installed in Oracle home.
The Inventory screen contains the following:
The Confirmation screen lists all the components selected for deinstallation in the Inventory screen. Scroll down the screen to verify selected components.
Note: Oracle Universal Installer does not delete all the files and directories during deinstallation. Remove remaining files manually. |
The following buttons appear on the Confirmation screen:
This screen presents one of the following messages:
Ora9ias_home
. There are no other Administration Services available.
This message appears when there is only one Oracle9iAS installation on the host and you are about to deinstall it.
Ora9ias_home
. You may select one of the Administration Services below to become the active one.
This message appears when there are multiple Oracle9iAS installations on the host and you are about to deinstall the primary installation. You can select one of the remaining Oracle9iAS installations which will then become the primary installation and the new location for the Oracle9iAS Administration Service.
The Remove Progress Bar screen appears when you click Remove. The installer detects all components chosen for deinstallation from the Inventory screen and removes them from Oracle home.
If you deinstall a product or component, then all of its dependent components and files will also be deinstalled.
Note:
The following steps remove all Oracle products from your computer.
The Registry Editor is displayed.
HKEY_LOCAL_MACHINE

For Windows 2000:
For Windows NT:
Highlight the Path System Variable. Click the Edit button and modify the Path in the Variable Value field.
Highlight the Path System Variable so that it appears in the Variable field. Modify the Path in the Value field.
For example, the following shows an Oracle-modified Path system variable:
C:\ias902a\iSuites\BIN;C:\ias902a\806\bin;C:\ias902a\iSuites\Apache\ Perl\5.00503\bin\mswin32-x86;C:\ProgramFiles\Oracle\jre\1.1.7\bin;C: \WINNT\system32;C:\WINNT;C:\WINNT\System32\Wbem;C:\ias902a\806\vbrok er\bin;C:\ias902a\806\jdk\bin
The following shows the Path system variable after removal of the Oracle home references:
C:\WINNT\system32;C:\WINNT;C:\WINNT\System32\Wbem
For Windows 2000:
For Window NT:
For Windows 2000:
For Windows NT:
TEMP
directory.
Click Start > Programs > Windows NT Explorer. Delete any Oracle home directories that are displayed on your installation hard drive.
For example:
C:\Oracle\*, C:\Program Files\Oracle\*
Oracle Universal Installer does not allow reinstallation of Oracle9iAS over an installed version. To reinstall Oracle9iAS over the same version, deinstall and then install the product.
If you deinstall an Oracle9iAS instance that uses an Oracle9iAS Infrastructure, you cannot reuse the same Oracle9iAS instance name of that deinstalled instance when installing subsequent Oracle9iAS instances. In order to reuse the Oracle9iAS instance name, you must manually delete the entry for the deinstalled Oracle9iAS instance in Oracle Internet Directory.
