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/systempw@connect_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/systempw@connect_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/systempw@connect_string
@co_drop_user.sql
