This chapter describes how to deinstall or reinstall B2B and Healthcare.
You should always use the instructions provided in this chapter for removing the software. If you try to remove the software manually, you may experience problems when you try to reinstall the software again at a later time. Following the procedures in this chapter will ensure that the software is properly removed.
This chapter contains the following sections:
The Oracle Fusion Middleware deinstaller removes the software from the Oracle home directory from which it is started. Table 6-1 summarizes the procedure and provides links to supporting documentation.
Table 6-1 Roadmap for Product Deinstallation
| Task | Description | Documentation |
|---|---|---|
|
Stop Oracle Fusion Middleware |
All servers and processes in your domain should be stopped before running the deinstaller. |
See Section 6.2. |
|
Remove your database schemas |
Run Repository Creation Utility to remove your database schemas. |
See Section 6.3. |
|
Remove the software |
Run the product deinstaller to remove B2B and Healthcare. Note that if your Oracle home contains multiple products, you will need to run the deinstaller multiple times; once for each product. |
See Section 6.4. |
|
Remove the Oracle home directory |
The deinstaller does not remove all files and folders from the Oracle home directory. After the deinstaller is finished, you must manually remove the Oracle home to complete your product removal. |
See Section 6.5. |
|
Remove your domain and application data |
The deinstaller does not remove data contained in your Domain home or Application home directories, even if they are located inside the Oracle home. You must remove these directories manually. |
See Section 6.6. |
Before running the deinstaller, you should stop all servers and processes associated with the Oracle home you are going to remove.
For more information, see "Stopping an Oracle Fusion Middleware Environment" in Administering Oracle Fusion Middleware.
Before your Oracle home is removed, you should run Repository Creation Utility to remove the database schemas associated with this domain. Each domain has its own set of schemas, uniquely identified by a custom prefix (see "Understanding Custom Prefixes" in Creating Schemas with the Repository Creation Utility). This set of schemas cannot be shared with any other domain (see "Planning Your Schema Creation" in Creating Schemas with the Repository Creation Utility).
If there are multiple sets of schemas on your database, be sure to identify the schema prefix associated with the domain you are removing.
For schema removal instructions, see "Dropping Schemas" in Creating Schemas with the Repository Creation Utility.
Follow the instructions in this section to start the product deinstaller and remove the software.
If you want to perform a silent (command-line) deinstallation, see "Running the Oracle Universal Installer for Silent Deinstallation" in Installing Software with the Oracle Universal Installer.
To start the deinstaller:
On Unix
To start the deinstaller on a UNIX operating system, go to the ORACLE_HOME/oui/bin directory and enter the following command:
./deinstall.sh
On Windows
Do one of the following:
Use a file manager window to go to the ORACLE_HOME\oui\bin directory and double click on deinstall.cmd.
From the command line, go to the ORACLE_HOME\oui\bin and enter the following command:
deinstall.cmd
From the Start menu, select All Programs, then select Oracle, then select OracleHome, and then select Uninstall Oracle Middleware.
Because multiple products exist in the Oracle home, ensure that you are deinstalling the correct Oracle home. After you run the deinstaller, the Distribution to Uninstall screen is displayed. From the drop-down list, select B2B_Healthcare 12.1.3.0.0 and click Uninstall. The deinstallation program displays the screens listed in Table 6-2.
Note:
You can deinstall Oracle Fusion Middleware Infrastructure once the Oracle B2B and Healthcare software is deinstalled, by running the deinstallation wizard again. You will not run into the Distribution to Deinstall screen if no other software is dependent on Oracle Fusion Middleware Infrastructure.
The deinstallation program displays a series of screens, in the order listed in Table 6-2.
If you need additional help with any of the deinstallation screens, click the screen name.
Table 6-2 Deinstall Screens and Descriptions
| Screen | Description |
|---|---|
|
This screen introduces you to the product deinstaller. |
|
|
This screen shows the Oracle home directory and its contents that will be deinstalled. Verify that this is the correct directory. If you want to save these options to a response file, click Save Response File and provide the location and name of the response file. Response files can be used later in a silent deinstallation situation. For more information about silent or command line deinstallation, see "Running the Oracle Universal Installer for Silent Deinstallation" in Installing Software with the Oracle Universal Installer. Click Deinstall to begin removing the software. |
|
|
This screen shows the progress of the deinstallation. |
|
|
This screen appears when the deinstallation is complete. Review the information on this screen, then click Finish to dismiss the deinstaller. |
After the deinstaller is finished, you must manually remove your Oracle home directory and any existing sub-directories that were not removed by the deinstaller. For example, if your Oracle home directory was /home/Oracle/product/Oracle_Home on a UNIX operating system:
> cd /home/Oracle/product > rm -rf Oracle_Home
On a Windows operating system, if your Oracle home directory was C:\Oracle\Product\Oracle_Home, use a file manager window and navigate to the C:\Oracle\Product directory, then right-click on the Oracle_Home folder and select Delete.
To remove your domain and application data:
Manually remove your Domain home directory.
For example, if your Domain home directory was /home/Oracle/config/domains/healthcare_domain on a UNIX operating system:
> cd /home/Oracle/config/domains > rm -rf healthcare_domain
On a Windows operating system, if your Domain home directory was C:\Oracle\Config\domains\healthcare_domain, use a file manager window and navigate to the C:\Oracle\Config\domains directory, then right-click on the healthcare_domain folder and select Delete.
Manually remove your Application home directory.
For example, if your Application home directory was /home/Oracle/config/applications/healthcare_domain on a UNIX operating system:
> cd /home/Oracle/config/applications > rm -rf healthcare_domain
On a Windows operating system, if your Application home directory was C:\Oracle\Config\applications\healthcare_domain, use a file manager window and navigate to the C:\Oracle\Config\applications directory, then right-click on the healthcare_domain folder and select Delete.
Backup the domain_registry.xml file in your Oracle home, then edit the file and remove the line associated with the domain you are removing. For example, to remove the healthcare_domain, find the following line and remove it:
<domain location="/home/Oracle/config/domains/healthcare_domain"/>
Save and exit the file when you are finished.
You can reinstall your software into the same Oracle home as a previous installation only if you have deinstalled the software according to the instructions in this chapter, including manually removing the Oracle home directory. When you reinstall, you can then specify the same Oracle home as your previous installation.
Consider the following cases where the Oracle home is not empty:
Installing in an existing Oracle home that contains the same feature sets.
The installer will warn you that the Oracle home you specified during the installation already contains the same software you are trying to install. Your options are to:
Select a different installation type. In this case, only the feature sets that do not already exist in the Oracle home directory will be installed.
Select a different Oracle home directory.
Installing in an existing, non-empty Oracle home.
For example, suppose that you have chosen to create your Domain home or Application home somewhere inside your existing Oracle home. This data is not removed during the deinstallation process, so if you attempt to reinstall into the same Oracle home, the installer will not allow it. Your options are to:
Deinstall your software from the Oracle home as described in this chapter, and then remove the Oracle home directory. After this is complete, you can reinstall and reuse the same Oracle home location, using the instructions in Chapter 2. Any domain or application data that was in the Oracle home will have to be re-created.
Select a different Oracle home directory.
