Installing Oracle Parallel Server

This chapter describes the installation and configuration tasks to create an operating Oracle Parallel Server. Specific topics discussed are:

• Oracle Parallel Server and Multiple Oracle Homes

• Step 1: Install Oracle8 Enterprise Edition and Oracle Parallel Server on Nodes

• Step 2: Install OSD Files

Oracle Parallel Server and Multiple Oracle Homes

When working with multiple Oracle homes with Oracle Parallel Server, keep the following in mind:

OraclePGMSService

OraclePGMSService supports multiple Oracle homes, but is only called from the last installed Oracle home. When the first Oracle home is installed with the Oracle Parallel Server Option, the OraclePGMSService service is created and the PGMS executable is installed in ORACLE_HOME\BIN\PGMS.EXE. When a second Oracle home is installed with the Oracle Parallel Server Option, PGMS.EXE is installed in the second Oracle home, and the OraclePGMSService only calls the PGMS.EXE from the second Oracle home (not the first).

Operating System Dependent (OSD) layer

Only one copy of the OSD layer can exist.

Additional Information: See Chapter 6, "Using Multiple Oracle Homes", of the Oracle8 Enterprise Edition Getting Started for Windows NT.

Step 1: Install Oracle8 Enterprise Edition and Oracle Parallel Server on Nodes

To install Oracle8 Enterprise Edition and Oracle Parallel Server:

1. Install Oracle8 Enterprise Edition on each of the nodes in the cluster, following instructions in Oracle8 Enterprise Edition Installation for Windows NT CD-ROM insert, and perform these tasks:
   1. Choose Oracle Parallel Server Option from the Select Catridges and Options dialog box.

      Note: The location of the Oracle Home can be different on each of the nodes.

   2. Choose None from the Select a Starter Database Configuration dialog box:

   2. If you plan to install Oracle Enterprise Manager, ensure the Oracle Intelligent Agent service OracleAgent is installed on the nodes. The Oracle Intelligent Agent allows Oracle Enterprise Manager to communicate with the database.

   Below is a a description of the Oracle Parallel Server components installed when the Oracle Parallel Option is chosen:

   This component...	Installs...
   Oracle Parallel Server Option	Oracle Parallel Server files DLM files SQL scripts and Oracle files for creating a four instance database OraclePGMSService service Oracle Parallel Server Manager Server (see below)
   Oracle Parallel Server Manager Server	OPSM files needed to manage instances from individual nodes. Additional Information: See "Managing Instances Using OPSM".

   Step 2: Install OSD Files

   A vendor-supplied Operating System Dependent (OSD) layer that passed certification must be installed after Oracle Parallel Server Option is installed.

   To create the Oracle Parallel Server instances and the OSD registry entries:

   1. For all nodes, see your OSD vendor documentation for instructions on installing OSD files.

   2. Continue to Chapter 5, "Configuring Oracle Parallel Server" to configure Oracle Parallel Server.
