Remove any demonstration and sample databases, database applications, objects, and files from the DBMS.

To remove an account and all objects owned by that account (using BI as an example):
DROP USER BI CASCADE;

To remove objects without removing their owner, use the appropriate DROP statement (DROP TABLE, DROP VIEW, etc.).

This is check:

make sure all example schemas are removed
select distinct(username) from dba_users where username in
('BI','HR','OE','PM','IX','SH','SCOTT');

Expected result:

Expected results: no rows returned. If rows are returned, then drop the users.
sqlplus / as sysdba
drop user bi cascade;
drop user hr cascade;
drop user oe cascade;
drop user pm cascade;
drop user is cascade;
drop user sh cascade;
drop user scott cascade;

and we said...

How about creating a file that drops if necessary and does not return errors, eg

conn / as sysdba
declare
  procedure du(p_user varchar2) is
  begin
    execute immediate 'drop user '||p_user||' cascade';
  exception
    when others then
      if sqlcode != -01918 then raise; end if;
  end;
hegin
  du('bi');
  du('hr');
  du('oe');
  du('pm');
  du('is');
  du('sh');
  du('scott');
end;

Then your ansible is going to be something along the lines of

- hosts: all
 vars:
 oracle_base: /u01/app/oracle
 oracle_home: /u01/app/oracle/product/19.10/dbhome_1
 target_dir: /tmp
 remote_user: oracle
 sudo_user: root
 sudo: false
 tasks: 

- name: copy sqlscript
 copy: src=files/{{ item }} dest={{ target_dir }} owner=oracle group=oinstall mode=0644
 with_items:
 - drop_sample_schemas.sql
 

- name: copy sqlscript
 action: shell unzip -oq {{ patch_dir }}/p6880880_112000_Linux-x86-64.zip -d {{ oracle_home }}  

- name: run sqlscript
 action: shell export ORACLE_HOME={{ oracle_home }}; cd {{ target_dir }}; $ORACLE_HOME/bin/sqlplus /nolog @drop_sample_schemas
 register: error_found
 failed_when: "'ORA-" passed.' in error_found.stdout"



(I stress - I'm no ansible expert)
