what does the "2"mean in SQL*Plus?

I am new to Oracle. And I have come across a problem.

Firstly,I want to check the privileges of the sysman account:

SQL>  select * from dba_sys_privs where grantee='sysman';

no rows selected

I know that it means there is no content in my view dba_sys_privs. But anyway,I have aready built a database. So, I try again, just shortening the statement:

SQL>  select * from dba_sys_privs
  2

So here are my two questions:

1. what happened to my database? I have already set up a database
2. what does the "2" mean? Does it mean the next row or something else?
