Oracle RMAN backup job stay on active but nothing happens. Not even an error.

Hi,

I have a Windows 2003 R2 x64 SP2 server with Oracle 10.2.0.4 and a Windows 2008 R2 Standard x64 SP1 with NBU 7.5.0.5.

I have a problem with RMAN backup (filesystem backup works fine), after “channel ch00: starting piece 0” line there is no error message, but nothing happens.

Nothing was changed on the servers and RMAN backup works until now.
