3 Database Installation Tasks

This chapter describes how to start Oracle Universal Installer and install Oracle Database 10g for z/OS products on your system. Review the information in Chapter 1, "Installation Overview" and complete the tasks listed in Chapter 2, "Preinstallation Tasks" before beginning the installation.

This chapter includes information on the following topics:

Overview
Installing the Oracle Database Software
Required Postinstallation Tasks

3.1 Overview

This chapter describes how to install the Oracle Database software. These installation instructions apply to the Oracle Database products.

Before you install the software, you must perform the necessary preinstallation tasks, including transferring the software to your z/OS system and extracting the files. For more information, refer to Chapter 2, "Preinstallation Tasks".

In most cases, you use the graphical user interface (GUI) provided by Oracle Universal Installer to install the software. However, you can also use Oracle Universal Installer to complete noninteractive installations, without using the GUI. See Appendix A for information on noninteractive installations.

3.2 Installing the Oracle Database Software

To start Oracle Universal Installer and install the software, perform the following tasks:

Note:

Do not use Oracle Universal Installer from an earlier Oracle Database release to install components from this release.

If necessary, log in as the user who will install the Oracle software, set the DISPLAY environment variable, and run the environment shell script or the environment variables created earlier.
To start Oracle Universal Installer, enter the following commands where directory_path is the path of the Disk1 directory on the hard disk:
```
$ /directory_path/runInstaller
```
If Oracle Universal Installer does not appear, then refer to the "X Windows Display Errors" section for information troubleshooting.
Use the following guidelines to complete the installation:
- Follow the instructions displayed in Oracle Universal Installer windows. If you need additional information, then click Help.
- During installation, blank lines will be written to the Telnet session display. This is normal.
- When Oracle Universal Installer prompts you to run a script with administrator privileges, which permits you to update the /usr/local/bin directory and set the extattr for the Enterprise Manager management agent nmo executable, the administrator must run the root.sh shell script which is located in the ORACLE_HOME directory. This script is not required unless you want to use the Enterprise Manager management agent.
  
  Enter a command similar to the following in a terminal where you are logged in as a system administrator user, then click Continue or OK:
```
$ /oracle/v10g/root.sh
```
- If you encounter errors while installing or linking the software, then refer to Appendix C for information on troubleshooting.
When the installation is complete, click Exit, then click Yes to exit from Oracle Universal Installer.

At this stage, the following will have been created:

A z/OS UNIX System Services file system populated with client executables and the necessary files to maintain them
PDS and PDSE files which contain the executable files
An ENV file in the Oracle home directory which can be used to configure the default environment settings

3.3 Required Postinstallation Tasks

You must perform the tasks described in the following sections after completing an installation:

Downloading and Installing Patches
Performing System Administrator Tasks
Configuring Other Oracle Products

3.3.1 Downloading and Installing Patches

Check the OracleMetalink Web site for required patches for your installation. To download required patches:

Use a Web browser to view the OracleMetalink Web site:
```
https://metalink.oracle.com
```
Log in to OracleMetalink.

Note:
If you are not an OracleMetalink registered user, then click Register for MetaLink! and follow the registration instructions.
On the main OracleMetalink page, click Patches.
Use the Simple Search feature to search by Product or Family.
Specify the following information, then click Go:
- In the Product or Family field, specify RDBMS Server
- In the Release field, specify the current release number
- In the Patch Type field, specify Patchset/Minipack

3.3.2 Performing System Administrator Tasks

Before you use the Oracle Database, you must perform various configuration tasks. Perform the following before using your Oracle Database for the first time:

APF-authorize the AUTHLOAD library.
Move load modules from the AUTHLOAD library to a system linklist PDSE and activate them. This can be done by configuring and running the batch job COPYPROC which has been provided as a sample in the INSTLIB PDS.

After running COPYPROC, you need to refresh the linklist library, by issuing the following command to a z/OS console:
```
F LLA REFRESH
```

3.3.3 Configuring Other Oracle Products

Many other Oracle products and options must be configured before you use them for the first time. Before using other Oracle Database 10g for z/OS products or options, refer to product-specific administration and tuning guides for detailed configuration and tuning information. For more information, refer to the "Related Documents" section in the Preface.
