You have a tablespace that was created with this command:

CREATE TABLESPACE CUSTOMERSERVICE

DATAFILE 'C:\temp\cust_serv01.dbf' SIZE 50M

AUTOEXTEND OFF;

Write a SQL script to accomplish these tasks:

a. Add another tile that is identical (except the name) to the original one.

b. Make the first datafile 25Mb in size.

c. Make the second datafile expandable forever.
