How can I build a tiny, straightforward database with Oracle 11g and SQL Developer? I'm seeing entirely too many problems, and I can't figure out how to create a straightforward database. For instance:
create database company;
Caused the following error:
Error starting at line 1 in command:
create database company
Error at Command Line:1 Column:0
SQL Error: ORA-01501: CREATE DATABASE failed
ORA-01100: database already mounted
01501. 00000 - "CREATE DATABASE failed"
*Cause: An error occurred during create database
*Action: See accompanying errors.
