What are you trying to copy? Data from one Oracle table to another?  An operating system file? Something else?

Absolutely No !

The copy command is a part of the product SQL*Plus, and it's neither an SQL command nor a Pl/Sql command.
You can find enforcements in Oracle's documentation, in the SQL*Plus book.

Regarding your second question, SQL*Plus copy command does generate redo data. In fact, everything you do in Oracle generates a redo data, except whenever you (can) use the 'UNRECOVERABLE' predict. For instance, the following command will not generate redeo data :
Alter index idx rebuild tablespace indexes unrecoverable;Create table a as select * from b;

The copy command simply does smart inserts.

Looks perfect. How can I check whether it generates redo or not?
