系统环境：rhel6.2_x64+Oracle RAC11g
操作过程：
1.非归档模式
SQL> archive log list;
Database log mode No Archive Mode
Automatic archival Disabled
Archive destination /u01/oracle/app/oracle/11.2.0/db/dbs/arch
Oldest online log sequence 303086
Current log sequence 303087

2.非系统表空间（当前为生产环境，节点RAC1可识别本地文件）
SQL> set line 180
SQL> col file_name for a60
SQL> col tablespace_name for a15
SQL> select file_name,file_id,online_status,tablespace_name from dba_data_files;
