Re: Checking free space on a raw device

One single Raw Device should be holding only one datafile. Normally, the datafile is created as the same size as the Raw Device [minus the header block overhead].

However, you can use
1. dd if=rawdevice of=/dev/null bs=1M

     and the count should show the size of the raw device. 2. query dba_data_files for the size of the Oracle Datafile in the raw device. The difference should be the "free space" -- space which you can resize/autoextend the datafile by.
