I believe this means the database cannot accept any more connections.

Connect 'as sysdba' and check the processes parameter then look at the number of sessions connected.

The online networking docs should be able to confirm the 'blocked' status meaning.

there is no database in this ..
 the database is in nomount stage. because i have to connect as auxiliary i have to issuse the command. when i am tried to the sstatus the listener is blocked for this instance.

Going from memory but I believe in nomount you cannot connect through the listener.  This is why it shows blocked.

You are unable to connect remotely.

Can you connect to rman locally (on the rman server itself)?

That question doesn't appear to be related to this one.

>>duplicate command i am getting the error which i earlied posted

What steps are you following?  I've not done any duplication using RMAN but I'm thinking you might have missed a step somewhere.

Here are the Oracle docs that talk about this:
