How to create a database for sample code from Tutorial/Book?

user8816970Sep 26 2012 — edited Sep 27 2012
I want to try out the sample code from [http://shop.oreilly.com/product/0636920013471.do] for the book SQL Pocket Guide 3rd Ed.

I have downloaded the oracle vm/appliance for oracle 11g2 and I have started sqlplus as sysdba.

I'm feeling overwhelmed with these links describing how to create a database:
[http://www.adp-gmbh.ch/ora/admin/creatingdbmanually.html]
[http://tldp.org/HOWTO/Oracle-7-HOWTO-3.html]
[http://www.adp-gmbh.ch/ora/admin/creatingdbmanually.html]

(1) What is the command to list the existing databases?
(2) What is the command to delete an existing database?
(3) When creating a new database with the create database command, is it necessary to specify the logfile, character set, national character set, datafile, sysaux datafile, undo tablespace, temp table space? Do these have reasonable defaults? I'm not sure what proper directories are to specify for Linux and the examples are for windows.
Can someone give me a simplified create database command to create a database called 3rdEdPocketGuide? Should I follow the example at [http://tldp.org/HOWTO/Oracle-7-HOWTO-3.html] and instead of orcl use 3rdEdPocketGuide?
(4) What command do I use to execute the script that comes with the book SQL Pocket Guide 3rd Ed? This is the script that has all the drop table, create table and insert commands in it.
(5) What command do I use in sqlplus to set the current default database prior to running this script? Perhaps this is the connect command? I don't want my script to create tables in the system database.
(6) I tried the command "connect 3rdEdPocketGuide" and it prompted for a password! Yikes! What password? Do I need to specify a password when I create a database? I cannot tell if I have successfully created such a database or it is just prompting me for a password to thwart malicious users. Is it is possible to create databases which don't require a password or maybe a zero length password?

Thanks
Siegfried
