2 Pre-installation Tasks for Installations in an Existing Oracle Home

This chapter describes the tasks that you must complete before you install the software in an existing Oracle home. It includes information about the following:

Pre-installation Tasks for Oracle Database 10g Products
Pre-installation Tasks for Oracle HTML DB

2.1 Pre-installation Tasks for Oracle Database 10g Products

When you select the Oracle Database 10g Products installation type, the Installer installs all of the products available through this installation type. Ensure that your system meets the requirements in the following sections before installing Oracle Database 10g Products.

2.1.1 Check the Oracle Database 10g Installation

Before using this installation type, make sure that your system has an Oracle Database 10g Oracle home. If it does not, you must install Oracle Database 10g before installing products with the Oracle Database 10g Products installation type.

See Also:

For information about installing Oracle Database 10g, see the Oracle Database Installation Guide for UNIX Systems.

2.1.2 Identify the Oracle Database 10g Oracle Home Directories

If necessary, identify the Oracle home directory used by the Oracle Database 10g installation. If you do not know the path of the Oracle home directory, check the oratab file as follows:

Solaris:
```
# more /var/opt/oracle/oratab
```
Other operating systems:
```
# more /etc/oratab
```

2.1.3 Check Disk Space Requirements

Verify that the file system that contains the Oracle home directory contains at least 1 GB of free disk space.

To check that the Oracle home directory has enough space, enter one of the following commands:

HP-UX:
```
# bdf oracle_home_path
```
Other operating systems:
```
# df -k oracle_home_path
```

2.2 Pre-installation Tasks for Oracle HTML DB

Note:

This section describes the pre-installation tasks that you must complete if you are installing Oracle HTML DB in an existing Oracle home directory that contains Oracle HTTP Server. See the following section for information about Oracle home directories that satisfy this requirement. Alternatively, you can install Oracle HTML DB with Oracle HTTP Server in a new Oracle home directory.

When you select the Oracle Database 10g Companion Products installation type, you can choose to install Oracle HTML DB in an existing Oracle HTTP Server Oracle home. Before installing Oracle HTML DB, make sure your system meets the requirements described in the following sections.

2.2.1 Identify an Appropriate Oracle HTTP Server Installation

Before installing Oracle HTML DB, make sure that the system has an Oracle home directory that contains Oracle HTTP Server release 9.0.4 or higher with mod_plsql. If it does not, you must install Oracle HTTP Server when you install Oracle HTML DB. The following Oracle homes satisfy these requirements:

Oracle HTTP Server release 9.0.4, which is also available on the Oracle Database 10g Companion CD
Oracle Application Server 10g
Oracle Enterprise Manager 10g

Note:

If you do not have an Oracle home directory that satisfies these requirements, you must install Oracle HTTP Server when you install Oracle HTML DB. See Chapter 3 for information about pre-installation tasks for Oracle HTTP Server.

2.2.2 Check Disk Space Requirements

Verify that the file system that contains the Oracle home directory contains at least 350 MB of free disk space.

To check that the Oracle home directory has enough space, enter one of the following commands:

HP-UX:
```
# bdf /httpserver_oracle_home_path
```
Other operating systems:
```
# df -k /httpserver_oracle_home_path
```

2.2.3 Check the Oracle Database Installation

Before installing Oracle HTML DB, identify the Oracle database that you want to use with Oracle HTML DB. The database must be Oracle9i release 9.2.0.3 or higher. The database can be on a different system from the system where you are installing Oracle HTML DB.

2.2.4 Check for Oracle XML DB

Oracle XML DB must be installed in the database that you want to use.

If you are using a preconfigured database created either during an installation or by the Database Configuration Assistant (DBCA), Oracle XML DB is already installed and configured. For information about manually adding Oracle XML DB to an existing database, see the Oracle XML DB Developer’s Guide.

2.2.5 Identify Database Information

During the installation, you must specify the following information about the database:

The host name of the database system
The port number of the Oracle Net listener
The service name of the database
The password of the SYS user

Make sure that you have this information before starting the installation.

See Chapter 4 for instructions on installing the Oracle Database 10g Companion Products installation type.
