1 Installation Overview

1.1 Overview of Oracle Database Installation

Oracle recommends that you review the installation process carefully before you begin. The new installation features and tasks are summarized in the following list:

• The Oracle software is compressed into installation files that can be loaded from the product DVDs or downloaded from an Oracle Web site, as described in Chapter 2. The installation files are in a PAX format. This is a method of compressing multiple files into a single object using the z/OS UNIX System Services shell command, pax.

• You must upload the installation files to z/OS using either File Transfer protocol (FTP) or network file system (NFS), and then extract the compressed files to a temporary location on your z/OS UNIX System Services file system. You must allocate either Hierarchical File System (HFS) or zFS temporary disk space for each task. Instructions on transferring the files to your z/OS system, as well as temporary disk space requirements are listed in Chapter 2.

• You will need to allocate permanent disk space for the installed products. This disk space includes HFS or zFS disk space and data set disk space. Chapter 2 describes the permanent disk space requirements.

• Oracle Universal Installer is a Java application requiring Java to be installed on your system. Software requirements are described in Chapter 2.

• You may need to configure z/OS UNIX System Services parameters and other system parameters depending on whether you are installing the Oracle Database software for the first time or upgrading an existing installation. This is described in Chapter 2.

• With Oracle Universal Installer, you can use either an interactive method or a silent method of installation. The interactive method, described in Chapter 3, uses the X server graphical display routines. When you use this method, you must have the X libraries installed on your z/OS system. In addition, you must be able to connect to an X server, a PC or UNIX system running the X server software. In this arrangement, the X server is the client and the X client is the z/OS server. Alternatively, you must modify a response file in the silent method of installation, as described in Appendix A.

  When you use the interactive method to install Oracle Database, Oracle Universal Installer displays a series of screens that enable you to specify all of the required information to install the Oracle Database software and optionally create a database. Help is available for most of these screens. In a noninteractive installation, you must create a response file and specify this file when you start the Oracle Universal Installer to automate some or all of the Oracle Database installation.

• After installation is complete, temporary files can be removed.

• The installation process creates an Oracle environment on z/OS UNIX System Services that is complete for the maintenance of Oracle products. This environment is similar to that of a UNIX system. On the TSO/Batch side you will have a number of PDS (Partitioned Data Set) and PDSE (Partitioned Data Set - Extended) data sets.

The Oracle Database installation process consists of the following phases:

1. Read the release notes: Read the Oracle Database 10g release 2 (10.2) release notes before you begin the installation. The release notes are available with the platform-specific documentation. The latest version of the release notes is available on Oracle Technology Network at

   http://www.oracle.com/technology/documentation/index.html

2. Planning your installation: This chapter describes the Oracle Database 10g for z/OS products that you can install, and issues that you must consider before starting the installation.

3. Completing preinstallation tasks: Chapter 2 describes preinstallation tasks that you must complete before installing the product.

4. Installing software: Use the following section to install Oracle Database:

   • Chapter 3 describes how to use Oracle Universal Installer to install Oracle Database and complete the database installation process.

   • Chapter 4 describes how to remove the Oracle software.

   • Chapter A provides information on performing noninteractive installations, which you may want to use if you need to perform multiple installations of Oracle Database.

   • Chapter B describes the Oracle Library data sets, and how to choose data set name qualifiers.

   • Chapter C provides troubleshooting advice in case you encounter problems with the installation.

1.2 Installation Considerations

This section contains information that you should consider before deciding how to install Oracle Database 10g software. It contains the following sections:

• Software Certification

1.3 Upgrade Issues

For information about upgrading a previous release of Oracle Database for z/OS to Oracle Database 10g for z/OS, refer to the Oracle Database Upgrade Guide and the Oracle Database System Administration Guide for IBM z/OS (OS/390).

1.4 Working in Shell Environments

Many installation-related tasks are performed in the z/OS UNIX System Services environment and utilize shell commands. Throughout this document, tasks that involve shell commands are prefixed with a dollar sign ($) followed by a space, which is the default prompt for the TTY shell provided by IBM. If you use a different shell such as the OMVS shell in TSO, the prompt may be different but the commands are generally the same. However, the OMVS shell requires using an editor other than vi in situations where a file must be edited.
