1. Introduction

This repository contains a copy of the Oracle Database sample schemas that are installed with Oracle Database Enterprise Edition 12c. These schemas are used in Oracle documentation to show SQL language concepts. The schemas themselves are documented in Oracle Database Sample Schemas, 12c Release 1 (12.1).

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.

2. Installing the Samples

CAUTION: Do not use install the samples if you already have user accounts named HR, OE, PM, IX, SH or BI.

The installation scripts are designed to run on a database host with Oracle Database 12.1, non CDB. Privileged database access is required during installation.

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

An alternative to using this repository is to download and install the Oracle Database 12c Release 1 Examples package for your platform.

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. Make a log directory

mkdir log

2.4. 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 

2.5. Set the Oracle environment

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.

2.6. 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/systempw
@mksample systempw syspw hrpw oepw pmpw ixpw shpw bipw users temp /your/path/to/log/

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.

2.7. 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

source /usr/local/bin/oraenv

3.2. Run the schema removal script

sqlplus system/systempw 
@drop_sch.sql

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