In this post, I’m going to explain how to install Oracle sample schemas, if they are not already installed.

If you created a database sing DBCA , you can select to install the sample schemas:

Or you can install sample schemas manually after the database creation as explained in this post.

Download the Scripts:

Starting from Oracle database 12.2 ,the sample schemas setup scripts are now available from GitHub. Pick the release that matches your database release:

https://github.com/oracle/db-sample-schemas/releases

Extract the files:

Extract the file “db-sample-schemas-19c.zip” directly into $ORACLE_HOME/demo/schema, replacing any existing files.

Adjust the Working Directory:

Run the following Perl command to replace “__SUB__CWD” tag in the scripts with your current working directory. If you are using an alternate working directory, change to that directory before running the Perl command.

cd $ORACLE_HOME/demo/schema
perl -p -i.bak -e ‘s#SUB__CWD#’$(pwd)’#g’ *.sql */*.sql */*.dat

Install all sample schemas at once:

The following schemas will be installed.

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

cd /u01/app/oracle/product/12.2.0/dbhome_1/demo/schema
sqlplus / as sysdba
@mksample oracle oracle hr oe pm ix sh bi users temp $ORACLE_HOME/demo/schema/log/ localhost:1521/orcl

where:
oracle: is the password for the system & sys users respectively.
hr is the password for the HR user.
oe is the password for the OE user.
pm is the password for the PM user.
ix is the password for the IXuser.
sh is the password for the SH user.
bi is the password for the HR user.

You may want to install only individual schemas (e.g. hR or OE), In this case follow the following procedure:

To Install the HR sample schema

In the following example, I’m going to install HR schema into a 19.3 pluggable database “PDB1”.

cd $ORACLE_HOME/demo/schema/human_resources


Then run the following script to create the HR schema:
@hr_main.sql

To Install the OE sample schema:

SQL> @?/demo/schema/order_entry/oe_main.sql

How to Drop Sample Schema (e.g. HR)?

Important Note:

If you are in Windows platform, and you don’t have “perl” installed, then you will need to modify the scripts manually to replace “__SUB__CWD__” with “”you working directory that holds the sample schema scripts like :(D:\app\db193\WINDOWS.X64_193000_db_home\demo\schema)”.

If you have cygwin terminal emulator ( or any similar one) installed in your windows machine, then you may use command similar to the following to find the files that contain the “__SUB__CWD__” keyword:

cd /cygdrive/d/app/db193/WINDOWS.X64_193000_db_home/demo/schema/order_entry
find . -name * | xargs -I{} grep -H -n “SUB__CWD” {}

What about scott schema >!. Ok, this may be the subject of my next post.
