Installation

This chapter describes using the Oracle Universal Installer to install a new Oracle8i Enterprise Edition and the Oracle Parallel Server Option installation.

Specific topics discussed are:

• Installation Types

• Installation Procedure

• Migrating or Upgrading to Release 8.1

• Multiple Oracle Homes

Installation Types

The type of installation and the type of database you choose to install determines the how you proceed with installation and configuration decisions.

When you run Oracle Universal Installer, you can choose to install Oracle8i Enterprise Edition and the Oracle Parallel Server Option with the following installation types:

Installation Type	Description
Typical	Installs a preconfigured starter database, licensable Oracle options and cartridges (including Oracle Parallel Server), networking services, Oracle8i utilities, and online documentation. This type of installation is recommended for new users or experienced users that want the complete database package. At the end of installation, the Oracle Database Configuration Assistant runs to create and start Oracle instances, copy data files, and initialize the database.
Custom	Note: Custom is only supported on Windows NT in release 8.1.5. Allows you to selectively install any product from the CD-ROM, including Oracle8i Enterprise Edition and Oracle Parallel Server on any subset of nodes in the cluster. If Oracle8 Enterprise Edition is chosen, you can choose to start the Oracle Database Configuration Assistant. From the Oracle Database Configuration Assistant, you may create a: starter database Online Transaction Processing (OLTP) database Decision Support System (DSS) database Hybrid database If you choose not to run the Oracle Database Configuration Assistant, you may run it at a later time or manually configure Oracle Parallel Server. If you choose not to install a database, you can install the Oracle Parallel Server Option and manually create the database.

Installation Procedure

During installation, software components are installed on the node from which the Oracle Universal Installer is run, and pushed to the other selected nodes in the cluster.

To install Oracle8i Enterprise Edition and the Oracle Parallel Server Option:

1. Ensure the tasks in "Pre-Installation Steps" were performed.

2. From the node where you intend to run the Oracle Universal Installer, verify you have administrative privileges to the other nodes.

   Operating System	Verification Method
   On UNIX	Perform a remote copy (rcp) to the other nodes.
   On Windows NT	Enter the following command for each node that is a part of the cluster: NET USE \\host_name\C$ where host_name is the host name defined in the DefinedNodes registry value for Cluster Manager. A successful connection results in "The command completed successfully." Oracle Corporation recommends using the same user name and password on each node in a cluster or use a domain user name. If you use a domain user name, log on under a domain with username and password which has administrative privileges on each node.

3. Install Oracle8i Enterprise Edition on one node in the cluster, following instructions in the:
   • Oracle8i Installation Guide for Sun Solaris, HP 9000 or AIX-based systems

   • Oracle8i Enterprise Edition Installation for Windows NT

4. Take note of the following tasks to perform for a successful Oracle Parallel Server installation:
   1. Select Oracle8i Enterpise Edition from the Available Products page.

   2. Select either Typical or Custom from the Installation Types page. See "Typical Installation" or "Custom Installation".

   3. If performing a Custom installation, ensure the Oracle Parallel Server option under the Oracle Database Options folder is selected in the Available Product Components page:

      The Oracle Universal Installer will not make Oracle Parallel Server Option visible unless Cluster Manager clusterware was properly configured. See your OSD vendor documentation for further information.

   4. Select the nodes to which you want the software installed from the Cluster Node selection screen page:

      
      

      The node on which you are running the installation is selected whether or not you select it.

      If the list of nodes does not includes nodes you expect, the vendor-supplied clusterware is either not installed, running, or configured properly. See your vendor documentation for further information.

      If clusterware is not installed, click Previous in the Oracle Universal Installer, install Cluster Manager on those nodes, then click Next in the Oracle Universal Installer. The nodes should now be listed.

   5. In the Database Identification page, enter an appropriate global database name, database name and domain, for the Oracle Parallel Server, such as OP.domain, and accept or change the prefix for the Oracle System Identifier (SID) that will be used in the SID field.

      Each instance will have a SID that consists of the common prefix entered here and a thread ID that is automatically generated. For example, if OP is entered, the first instance in the cluster will have a SID of OP1, and the second instance will have a SID of OP2.

      During installation no message appears to indicate components are installed to the other nodes.

Typical Installation

If you choose a Typical installation type, the Oracle Database Configuration Assistant is run automatically to create the database with no user input. The information entered in the Database Identification page is used by the Oracle Database Configuration Assistant to identify the database and each instance's SID.

The Oracle Database Configuration Assistant verifies the raw devices file names were created for each tablespace that will be created. Raw devices and file names should have been configured in "Setting Up Raw Devices". If the file names were not set up, the Oracle Database Configuration Assistant will fail to create the database.

Among the files installed, Typical results in the creation of these files:

• INITDB_NAME.ORA for general parameters shared by all instances

• INITSID.ORA files for each instance in the cluster

See "Understanding the Initialization Files" for further information about these files.

Note: If the Oracle Database Creation Assistant fails to create the database, see "Cleaning Up the Registry After an Oracle Database Configuration Assistant Failure on Windows NT".

Custom Installation

During the a Custom installation, the following products run, prompting for user input:

• Net8 Configuration Assistant

• Oracle Database Configuration Assistant

Net8 Configuration Assistant

The Net8 Configuration Assistant prompts you to configure the network. The Net8 Configuration Assistant only allows you to configure some aspects of the network for the node the Oracle Universal Installer is running on. Follow these recommendations:

1. Follow the Net8 Configuration Assistant prompts to configure the listener for the node by identifying a listener name and listener protocol address that uses TCP/IP on port 1521. TCP/IP is required for Oracle Enterprise Manager.

   Note: If you do not choose the registered port of 1521, you must configure the LOCAL_LISTENER parameter in the INITDB_NAME.ORA file and resolve it with a net service name entry in the TNSNAMES.ORA file. For further information about configuring non-default port numbers in LISTENER.ORA, see Chapter 6, "Configuring Naming Methods and the Listener" in the Net8 Administrator's Guide.

2. When asked to configure naming methods, select No, do not configure naming methods. Oracle Parallel Server requires more advanced naming method configuration than is available through the Net8 Configuration Assistant.

See "Configuring Net8 for Nodes" to complete network configuration for this node and other nodes in the cluster.

Oracle Database Configuration Assistant

The information entered in the Database Identification page is used by the Oracle Database Configuration Assistant to identify the database name and each instance's SID.

The Oracle Database Configuration Assistant verifies the raw devices file names were created for each tablespace that will be created. Raw devices and file names should have been configured in "Setting Up Raw Devices". If the file names were not set up, the Oracle Database Configuration Assistant will fail to create the database.

If you chose a Custom installation type, you are prompted with a choice to create a database:

• using the Oracle Database Configuration Assistant during installation

• sometime after installation using either the Oracle Database Configuration Assistant or other manual methods.

  See "Creating the Database" to create a database with the Oracle Database Configuration Assistant after installation.

If you choose to create a database using the Oracle Database Configuration Assistant, the following page appears:

Option	Description
Copy existing database files from the CD	Creates a standard starter database with parameters for each instance in INITSID.ORA and common parameters shared from node-to-node in INITDB_NAME.ORA.
Create new database files	Customizes the creation of the following database types. Online Transaction Processing (OLTP) database Decision Support System (DSS) database Hybrid database (combination of OLTP and DSS)

Respond to instructions in each Oracle Configuration Database Assistant page, then click Next when you are ready to continue to the next screen. When the last page displays, click Finish to start the creation of the Oracle Parallel Server database.

Migrating or Upgrading to Release 8.1

If the Oracle Universal Installer detects an earlier version of an Oracle database on your hard drive, you will prompted to migrate or upgrade the database to release 8.1. Do not click the Migrate an Existing Database check box, as the Oracle Data Migration Assistant does not support Oracle Parallel Server. Use the Migration utility to migrate after installation, as described in the Oracle8i Migration guide.

Note: Migrating or upgrading on Windows NT involves disabling the OraclePGMSService and dealing with the Operating System Dependent layer. The handling of the Operating System Dependent layer can be quite involved, especially during a migration. These instructions are not covered in the Oracle8i Migration guide. See Oracle8i Parallel Server Getting Started for Windows NT for complete migration and upgrade steps.

Take note of the following:

• Coexistence of different versions of the database is platform-specific. See the appropriate installation guide:
  • Oracle8i Installation Guide for Sun Solaris, HP 9000 or AIX-based systems

  • Oracle8i Enterprise Edition Installation for Windows NT

• Rolling upgrades--where different databases, or different instances of the same database in Oracle Parallel Server, are upgraded to a new version of Oracle one at a time--are not supported.

Multiple Oracle Homes

Like a regular Oracle8i Enterprise Edition database, the Oracle Parallel Server Option on UNIX supports multiple Oracle homes, a feature that allows you to install one or more releases on the same machine (in multiple Oracle home directories). Windows NT supports multiple Oracle homes, but all the Oracle homes must contain the same release of the Oracle8i Enterprise Edition and the Oracle Parallel Server Option.

Both UNIX and Windows NT require that each node have only one copy of the vendor-supplied Operating System Dependent layer active.
