Starting with Oracle Database 12c Release 2, the latest version of the sample schema scripts are available on GitHub at https://github.com/oracle/db-sample-schemas/releases/latest.

During a complete installation of Oracle Database, the HR schema can be installed either manually or automatically when creating a database using the dbca option. All the other sample schemas must be installed manually via the scripts available on GitHub.

This chapter contains the following topics:

2.1 Installing HR Schema Only

This section contains the following topics:

2.1.1 Installing HR Schema Using Database Configuration Assistant

Select the sample schemas option to install HR schema in the database.

At the end of the installation process, a dialog box displays the accounts that have been created and their lock status. By default, sample schemas are locked and their passwords are expired. Before you can use a locked account, you must unlock it and reset its password. You can unlock the accounts at this point in the installation process. Alternatively, after the installation completes, you can unlock the schemas and reset their passwords by using the ALTER USER ... ACCOUNT UNLOCK statement. For example:

ALTER USER hr ACCOUNT UNLOCK IDENTIFIED BY Password;

2.1.2 Manually Installing the HR Schema

All scripts necessary to create the Human Resource (HR) schema reside in $ORACLE_HOME/demo/schema/human_resources.

You need to call only one script, hr_main.sql, to create all the objects and load the data. The following steps provide a summary of the installation process:

Log on to SQL*Plus as SYS and connect using the AS SYSDBA privilege.
```
sqlplus connect sys as sysdba
Enter password: password
```
To run the hr_main.sql script, use the following command:
```
SQL> @?/demo/schema/human_resources/hr_main.sql
```

Enter a secure password for HR

specify password for HR as parameter 1:
Enter value for 1:

Enter an appropriate tablespace, for example, users as the default tablespace for HR

specify default tablespace for HR as parameter 2:
Enter value for 2:

Enter temp as the temporary tablespace for HR

specify temporary tablespace for HR as parameter 3:
Enter value for 3:

Enter your SYS password

specify password for SYS as parameter 4:
Enter value for 4:

Enter the directory path, for example, $ORACLE_HOME/demo/schema/log/, for your log directory
```
specify log path as parameter 5:
Enter value for 5:
```

After script hr_main.sql runs successfully and schema HR is installed, you are connected as user HR. To verify that the schema was created, use the following command:

SQL> SELECT table_name FROM user_tables;

Running hr_main.sql accomplishes the following tasks:

Removes any previously installed HR schema
Creates user HR and grants the necessary privileges
Connects as HR
Calls the scripts that create and populate the schema objects

For a complete listing of the scripts and their functions, refer to HR Sample Schema Scripts and Objects.

A pair of optional scripts, hr_dn_c.sql and hr_dn_d.sql, is provided as a schema extension. To prepare schema HR for use with the directory capabilities of Oracle Internet Directory, run the hr_dn_c.sql script. If you want to return to the initial setup of schema HR, use script hr_dn_d.sql to undo the effects of script hr_dn_c.sql.

You can use script hr_drop.sql to drop schema HR.
