【問題分析和解決】
從上面的錯誤來看，應該是對應的權限操作的問題，經瞭解，是關於/var/tmp目錄下的.oracle文件權限

[oracle@oracle tmp]$ ls -al
total 12
drwxrwxrwt  3 root root 4096 Nov 13 15:32 .
drwxr-xr-x 22 root root 4096 Aug 25  2011 ..
drwxrwxrwt  2 root root 4096 Nov 13 15:30 .oracle (注意這個文件是隱藏文件)
chmod 777 /var/tmp/.oracle

或者是

[oracle@oracle tmp]$  chown -R oracle.dba .oracle/
