Today, I know how to wrap Oracle objects called stored procedure, functions, views and so on. It's because I want to make secure for our project source.
How-to-do is very simple.
1) Open common prompt 2) and go to Bin folder under Oracle just like "C:\Oracle\Bin" 3) Then type following script
C:\Oracle\Bin\wrap iname=/SP/mysp.sql oname=/SP/wrap_mysp.sql
