ORA - Fixed schema creation (indexes, triggers and secuences):

Browse Source 
Indexes: The solution of put the index name of the first columnt dont't
work because duplicates, create instead a hash of the large name (PHP 5
>= 5.1.2, PECL hash:1.1-1.5) with an fixed char at beginning (Oracle
objects names can't start with a number)

Secuences & triggers: create a a hash of the large name.
