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 downloaded from the Oracle Support Web site, as described in Chapter 2. The installation files are in the zip format.

• 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. Chapter 2 lists the instructions on transferring the files to your z/OS system and the temporary disk space requirements.

• You must 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.

• 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.

• 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 many 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 Release Notes for IBM z/OS on System z 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/technetwork/indexes/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 install the Oracle Database software and complete the database installation process.

   • Chapter 4 describes how to remove the Oracle software.

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

1.2 Installation Considerations

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 on System z.

1.4 Working in Shell Environments

Some installation-related tasks are performed in the z/OS UNIX System Services environment and use 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.
