This chapter contains the following topics to help you to deinstall Oracle Fail Safe:
You might want to deinstall Oracle Fail Safe, for example, to remove older software such as Oracle Fail Safe release 2.1.3, or to move Oracle Fail Safe software to another Oracle home. However, do not use the deinstallation instructions in this chapter as a method for upgrading the Oracle Fail Safe software to the current release. See Appendix A for information about performing a rolling upgrade. See Appendix B for information about performing a silent mode deinstallation.
Caution:
Do not remove the Microsoft Cluster Server (MSCS) software without first deinstalling Oracle Fail Safe. Removing the MSCS software while Oracle Fail Safe is running will cause all MSCS metadata to be deleted, producing undesirable results. See Section 5.3 for more information.Deinstalling Oracle Fail Safe software involves removing resources from groups and reconfiguring them to run on a specific cluster node.
Perform the following steps to remove Oracle Fail Safe software.
Step 1 Remove cluster resources from groups configured with Oracle Fail Safe Manager.
This step must be performed only on groups that were configured with Oracle Fail Safe. Do not perform this step on groups that were configured with MSCS (such as the Cluster Group).
Using Oracle Fail Safe Manager, perform the following tasks:
Move each group to the node that will host the standalone resources after Oracle Fail Safe is deinstalled.
Remove all resources from your groups.
Delete all groups.
Exit Oracle Fail Safe Manager.
Step 2 Start Oracle Universal Installer and deinstall software.
Start the Oracle Universal Installer and perform the following tasks:
Click Deinstall Products to display Inventory dialog box.
Select the Oracle home that contains the Oracle Fail Safe release 3.n software.
Expand the tree view and select the check box next to Oracle Fail Safe 3.n.
Click Remove.
Step 3 Exit Oracle Universal Installer.
Click Exit to exit Oracle Universal Installer.
To deinstall Oracle Fail Safe release 2.0.5, 2.1.2, or 2.1.3, you must use Oracle Installer (the predecessor to Oracle Universal Installer). You cannot use Oracle Universal Installer to deinstall releases of Oracle Fail Safe that were installed with Oracle Installer.
Perform the following steps to remove Oracle Fail Safe software.
Note:
Do not perform Step 1 if you are performing a rolling upgrade.Step 1 Remove all resources and delete all groups.
This step must be performed only on groups that were configured with Oracle Fail Safe. Do not perform this step on groups that were configured with MSCS (such as the Cluster Group).
Perform the following tasks by using Oracle Fail Safe Manager:
Move each group to the node that will host the standalone resources after Oracle Fail Safe is deinstalled.
Remove all resources from your groups.
Delete all groups.
Exit Oracle Fail Safe Manager.
Step 2 Start Oracle Installer.
Start Oracle Installer. If Oracle Installer is not available from the Microsoft Windows Start menu, you can access it on the Oracle Fail Safe CD-ROM in the \OracleInstall directory. Double-click Orainst.exe in the \OracleInstall directory to start Oracle Installer.
This runs Oracle Installer, which is the installer that you must use to deinstall Oracle Fail Safe release 2.1.3 or earlier releases.
Step 3 Remove the Oracle Fail Safe components.
In the Oracle Installer Software Asset Manager dialog box, select Oracle Fail Safe Server, Oracle Fail Safe Manager, or both from the Installed Products window and click Remove to deinstall them.
Step 4 Unregister the Oracle Fail Safe resource DLL from MSCS.
Typically, you must click Yes when you are deinstalling the Oracle Fail Safe software. However, the following list provides more information to help you decide whether to answer Yes or No when you are prompted to unregister the Oracle resource from the cluster.
Click Yes to unregister the Oracle Database resource and remove all Oracle Fail Safe information from the cluster database and registry.
This option also unregisters the Oracle Database resource type from MSCS. Select this option when:
You do not want to use Oracle Fail Safe on any cluster node.
You do not have any databases configured in an Oracle Fail Safe group on the cluster nodes.
Click No to remove all Oracle Fail Safe files installed on this node without unregistering database resources and removing the Oracle Database resource DLL files.
This option helps you to remove one node from the cluster while the other node or nodes continue to run Oracle Fail Safe. For example, you must choose this option if one node in the cluster fails or needs maintenance and you need to replace it with a different system, or if you are upgrading Oracle Fail Safe software.
