REM 
REM HR sample schema wrapper.
REM
REM This script tries to be a "one and done" script to load the HR schema
REM by guiding the novice as best as possible to ensure a sucessfull installation
REM of the schema.  Things it will endeavour to do:
REM
REM  - not let you install into a root container by mistake
REM  - make sure you are connected correctly
REM  - if you are connected as HR, we'll try reload the schema objects and keep the user
REM  - if you are connected not as HR, we'll try drop/recreate the HR schema
REM  - we check for required privs in the HR schema
REM  - we check for required privs for an admin to build the HR schema from scratch
REM  - we check for appropriate tablespace quotas
REM  - we check for default tablespaces
REM  - we check for existing sessions as HR which would block a drop
REM  - we check for OS file writability for spool files
REM
REM In all cases, we try to provide guidance on remedial action to follow if 
REM the installation fails or cannot proceed.
REM
REM Like anything, you could come up with a bizarre set of circumstances in which
REM this can be broken, but it should work for most. If you do you break it, please
REM get in touch so I can make it even more carefree for beginners.
