SQL & PL/SQL

I am getting an error saying i do not have previledge to execute ddl at remote database.
dmls are executed sucessfully.

I need to know which grant should be given to me by the sysdba of remote db so that i can execute ddls too.
Tried to find the solution on net.It says "need proper priviledge" can i know exectly which grant do i need?

SQL> conn dushyant/dushyant@orcl;

TNAME TABTYPE CLUSTERID
