1. Introduction

This repository contains a copy of the Oracle Database sample schemas that are installed with Oracle Database Enterprise Edition. These schemas are used in Oracle documentation to show SQL language concepts and other database features. The schemas themselves are documented in Oracle Database Sample Schemas.

The schemas are:

• HR: Human Resources
• OE: Order Entry
• PM: Product Media
• IX: Information Exchange
• SH: Sales History
• BI: Business Intelligence

Due to widespread dependence on these scripts in their current form, no pull requests for changes can be accepted.

In addition, a new schema CO: Customer Orders, is now also included in this repository. It is not automatically installed along with the rest of the schemas at this time. Follow instructions in that schema's README to install the CO schema.

2. Installing the Samples

CAUTION: The first step in installing sample schemas is to drop user accounts with the following names: HR, OE, PM, IX, SH and BI. Do not proceed with the installation if you have schemas with any of these names that you wish to keep.

The installation scripts are designed to run on an Oracle Database.
Privileged database access is required during installation.

The instructions below work on Linux and similar operating systems. Adjust them for other platforms.

2.1. Clone this repository

Login as the Oracle Database software owner and clone the repository, for example

cd $HOME
git clone https://github.com/oracle/db-sample-schemas.git

or download and extract the ZIP file:

unzip db-sample-schemas.zip

The schema directory should be owned by the Oracle Database software owner.

2.2. Change directory

cd $HOME/db-sample-schemas

2.3. Change all embedded paths to match your working directory

The installation scripts need your current directory embedded in various locations. Use a text editor or the following Perl script to make the changes, replacing occurrences of the token __SUB__CWD__ with your current working directory, for example /home/oracle/db-sample-schemas

perl -p -i.bak -e 's#__SUB__CWD__#'$(pwd)'#g' *.sql */*.sql */*.dat 

2.4. Set the Oracle environment

Skip this step when running on a client machine (one without an Oracle Database installed).

source /usr/local/bin/oraenv

Note: Oracle's sqlldr utility needs to be in $PATH for correct loading of the Product Media (PM) and Sales History (SH) schemas.

2.5. Run the installation script

Review the README.txt for information on passwords and pre-requirements. In particular, verify your default and temporary tablespace names, and choose a password for each schema.

Start SQL*Plus and run the top level installation script as discussed in README.txt:

sqlplus system/[email protected]_string
@mksample systempw syspw hrpw oepw pmpw ixpw shpw bipw users temp /your/path/to/log/ connect_string

Note: Use an absolute path and also append a trailing slash to the log directory name.

Use your current SYSTEM and SYS passwords, and also your actual default and temporary tablespace names. The passwords for the new HR, OE, PM, IX, SH and BI users will be set to the values you specify.

Reminder: currently the CO schema will not be installed as part of this process.

Using a connect string permits connections to non-container databases and pluggable database using the same syntax.

An example of connect strings for databases with services noncdb and pdb:

  localhost:1521/noncdb
  localhost:1521/pdb

2.6. Review the installation logs

Review output in your log directory for errors.

3. Removing the Samples

CAUTION: This will drop user accounts named HR, OE, PM, IX, SH and BI.

3.1. Set the Oracle environment

Skip this step when running on a client machine (one without an Oracle Database installed).

source /usr/local/bin/oraenv

3.2. Run the schema removal script

sqlplus system/[email protected]_string
@drop_sch.sql

When prompted, enter the SYSTEM password, a log file name, and connect string.

3.3 Run the CO schema removal script

If you have installed the CO schema, run the following script to remove it.

sqlplus system/[email protected]_string
@co_drop_user.sql
