We are using Oracle 18.104.22.168.0 on HP-UX11i, 64bit version. It's a two node RAC DB clsuter. We have created initally some tablespaces with big sizes. Now as we are facing some storage problems on our SAN, we want to reduce the sizes to appropriate sizes and also drop unnecessary tablespaces. But the problem is we are using RAW Volumes instead of filesystem. So, Please help me in this regard.
