Customizing Sun Cluster HA for Oracle

Overview

SunPlex^TM Manager uses the Oracle Universal Installer to install Oracle and configure Sun Cluster HA for Oracle. For a list of Oracle releases that are supported for use with Sun^TM Cluster, ask your Sun sales representative.

SunPlex Manager sets up a "Typical" Oracle installation type. See the Oracle documentation for details.

Oracle is a complex product and the configuration possible through SunPlex Manager is limited. You must have a thorough understanding of Oracle before using the SunPlex Manager installation. See the Oracle documentation for details.

You must configure Sun Cluster HA for Oracle as a failover service.

For a more advanced configuration, you might be able to manually customize your configuration after SunPlex Manager completes the installation. See the Oracle documentation for details.

To completely customize your Sun Cluster HA for Oracle installation, following the instructions in the SunCluster 3.0 Data Services Installation and Configuration Guide or the Oracle documentation.

Before Starting

Before you install Sun Cluster HA for Oracle, check the following items.

Ensure the logical hostname is set up. This should have been done when Sun Cluster was installed. If not, see Creating a Logical Hostname Resource.
Ensure that your system meets the Oracle system installation requirements. See the Oracle installation documentation for details.
Verify that you have sufficient swap space. See the Oracle documentation for Oracle's swap requirements.
Determine where to install the Oracle application files (Oracle binaries, configuration files, and parameter files) and database-related files (control file, redo logs, and data files). The Oracle application files can be installed locally or globally. The database-related files must be installed globally.
Configure the UNIX^R kernel for Oracle 8i as specified in the Oracle installation documentation.
Oracle requires special settings for kernel variables that are related to shmsys and semsys. These variables are set in the /etc/system file and changes are activated after the system is rebooted. If you have not rebooted since you last modified these settings, reboot the cluster nodes before you begin the Sun Cluster HA for Oracle installation. See the Oracle installation documentation for more information.

Reboot your cluster nodes if you have made any changes to the /etc/system file since your last reboot.

Note: If no entries exist for the shmsys and semsys variables in the /etc/system file when the SunPlex Manager packages are installed, default values for these variables are automatically put in the /etc/system file. The system must then be rebooted. Check Oracle installation documentation to verify that these values are appropriate for your database.

Installing Sun Cluster HA for Oracle


	Sun Cluster HA for Oracle takes approximately three hours to install.



	When you exit the Cluster Manager or click Back in your browser window after you begin installing, the data service disconnects you from the installation. This disconnection can result in an incomplete installation because of insufficient information or an unresolved error message. To clean up an incomplete installation, you must remove the application files and any resources and resource groups that were created.

To install Sun Cluster HA for Oracle, complete the following steps.

In a terminal window, use the xhost command to enable all of the cluster nodes to display the Oracle installer windows on the workstation you are using.
xhost [node names]
Display the cluster overview page by selecting [cluster name] Cluster from the SunPlex Manager navigation frame.
SunPlex Manager displays the Cluster window.
Choose Oracle Database from the Install Data Service menu.
SunPlex Manager checks for the following.
- Are the Sun Cluster HA for Oracle data service packages already installed?
- Are the Sun Cluster HA for Oracle data services registered with RGM?
If all of these items are installed or exist, proceed to the next step.
If SunPlex Manager does not find SUNW.oracle.server and/or SUNW.oracle.listener installed, SunPlex Manager prompts you through installing and registering these resource types. You must provide the location of the Sun Cluster 3.0 Agents CD.
SunPlex Manager then displays a page that prompts for installation information.
Choose the type of installation appropriate for your system.
- Install Oracle and database - Choose this type of installation if you want to install Oracle and create a sample database.
- Install Oracle and an existing database - This option only appears if a database is already installed on the cluster.
SunPlex Manager displays a configuration page. SunPlex Manager attempts to find reasonable default values for the configuration information.

Modify the information on the configuration page for your system.

Field	Description
X Display to Use	The name of the display that is used to display the Oracle installer window. The cluster nodes must have xhost access to this display. This should be the display you are using for the browser.
Directory Holding Oracle CD ROM Image	The directory that contains the "runInstaller" command.
ORACLE_BASE directory	The directory at the top of the Oracle software and administrative file structure.
ORACLE_HOME directory	The directory that contains the Oracle software for a specific release. This is the home directory for the Oracle application.
Database Name	The full database name that uniquely distinguishes it from any other database in your network domain.
Database Directory	The path of the database file mount point. This path must be a global file system on a different disk than ORACLE_BASE.

Click Install to install Sun Cluster HA for Oracle by using the parameters that you have set on the configuration page.

SunPlex Manager verifies the information on the configuration page. If it finds no errors, SunPlex Manager loads the Oracle Universal Installer and begins to install Oracle. If SunPlex Manager discovers any errors, it displays an error message.

Do not click Continue in the SunPlex Manager window while the Oracle Universal Installer is installing Oracle. You must wait until the installer is finished, then click Okay in the Oracle Universal Installer window before you proceed in the SunPlex Manager window.

Note: If you're installing Oracle to a local file system, you'll get one Oracle Universal Installer window for each node, since a separate install is necessary on each node. If you're installing Oracle to a global file system, you get one installer window.
The progress bars in the various Oracle Universal Installer windows might grow to 100% several times during the installation. Wait until the installer displays the dialog box that states the Database creation is complete before proceeding.

The Oracle Universal Installer displays a dialog box stating that the Database creation is complete and the database information that was created.

Click Okay to dismiss the Oracle Universal Installer and continue with the Sun Cluster HA for Oracle installation.
SunPlex Manager also displays a confirmation message.
Click Continue to run the root.sh script. If a dialog box displays that states the transfer was interrupted, ignore this message.
SunPlex Manager displays a confirmation message.
Click Continue to set up the configuration files.
SunPlex Manager displays a configuration page and attempts to find reasonable default values for the configuration information.

Modify the information on the configuration page for your system.

Field	Description
Network Resource	The logical hostname that is used to access the database.
Prefix for Oracle Resources	The listener resource has "-listener" appended to this prefix and the server resource has "-server" appended to this prefix.
ORACLE_HOME directory	The directory that will contain the Oracle products.
Database Name	The full database name that uniquely distinguishes it from any other database in your network domain.
Connection ID/Password	The connection ID and password that the fault monitor uses to connect to the database.
