Oracle file backup error: "The media surface is damaged"
I was going to do a Unicode Conversion of SAP BW7, and before this, it need to have a backup of the SAP and Oracle file.
But when I doing a Oracle file backup with cp command,
"cp -fprh /oracle/BW2"
has the following error.
" /oracle/BW2/sapdata4/bw2_2/bw2.data2: The media surface is damaged "
Does anyone has the experience of solving this problem?
Thank you very much!
