Sun Cluster HA for Oracle
Jump Back to Data Service Configuration PageBack to "Data Service Configuration"

Overview

SunPlexTM Manager uses the Oracle Universal Installer to install the Oracle® software and to configure Sun Cluster HA for Oracle. For a list of Oracle releases that are supported by SunTM Cluster, contact your Sun sales representative.

SunPlex Manager sets up a "typical" Oracle installation. For more information about this type of installation, see the Oracle documentation. Because of the complexity of the Oracle product, the configuration possible through SunPlex Manager is limited. For more information about configuration options, see the Oracle documentation.

You must configure Sun Cluster HA for Oracle as a failover service. To do so, you must include this application in a failover resource group.

To customize your Sun Cluster HA for Oracle installation, follow the procedures in the Oracle documentation or the Sun Cluster documentation.

Installing Sun Cluster HA for Oracle

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

If you exit SunPlex Manager or click the Back button in your Web browser after you begin the installation, the installation is disconnected. This disconnection can result in an incomplete installation because of insufficient information or an unresolved error message.

To clean up an incomplete installation, remove the application files, the resources, and the resource groups that were created.

To install Sun Cluster HA for Oracle, open a terminal window and type:

# xhost node_names

You can then display the Oracle installer windows on the workstation that you are using.

The following table describes the fields you fill in during installation:

Field Description
X Display to Use The name of the display used for the Oracle installer window.

The cluster nodes must have xhost access to this display. You must specify the display that you will use to view the web 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 home directory that contains the Oracle software for a specific release.
Database Name The full database name that uniquely distinguishes the database from other databases in your network domain.
Database Directory The path of the mount point for the database file. This path must be a global file system on a different disk than the ORACLE_BASE directory.

Note: Do not click Continue in SunPlex Manager window while the Oracle Universal Installer is installing Oracle. Wait until the installer is finished, then click OK in the Oracle Universal Installer window before you proceed in the SunPlex Manager window.

Note: If you are installing Oracle on a local file system, one Oracle Universal Installer window appears for each node. A window appears for each node because each node requires a separate installation. If you are installing the Oracle software on a global file system, one installer window appears.

The progress bars in the various Oracle Universal Installer windows might grow to 100 per cent several times during the installation. Before proceeding, wait until the installer displays the dialog box that states that the database has been created.

The following table describes additional input required during installation:

Field Description
Network Resource The logical host name that is used to access the database.
Prefix for Oracle Resources The field that describes the listener resource. The listener resource has "-listener" appended to this prefix, and the server resource has "-server" appended to this prefix.
ORACLE_HOME directory The directory for the Oracle products.
Database Name The full database name that uniquely distinguishes that database from other databases in your network domain.
Connection ID/Password The connection ID and password that the fault monitor uses to connect to the database.
Alert Logfile Location The location of the alert file.
Listener Name The name of the Oracle listener process.

Note: To test the data service, set up a tnsnames.ora file on a client as specified and connect to the database.
