Hi Friends,
I am practicing RMAN on my machine. For disaster recovery I deleted all my files ( moved them to other location) from the location including .dbf files, control files, redo log files.
Now as per steps, I first tried to connect to rman with command,
$ rman target/ nocatalog
or
$ rman target/ catalog cat/cat@tosingh (* tosingh is the netservice name for my recovery catalog server)
but I get the error :

Please help me out. I am not sure. I am not sure, which crucial step I am missing.
Thanks,
Mandy
