测试2：
（1）一致性的全备
SQL> shutdown immediate;
$ cp -rf $ORACLE_BASE/oradata/boss/*.dbf /oradata/bossbak/20140610allbackup
$ cp -rf $ORACLE_BASE/oradata/boss/*.log /oradata/bossbak/20140610allbackup
$ cp -rf $ORACLE_BASE/oradata/boss/*.ctl /oradata/bossbak/20140610allbackup
$ cp -rf /oradata/boss/control01.ctl /oradata/bossbak/20140610allbackup
$ cp -rf $ORACLE_HOME/dbs/spfileboss.ora /oradata/bossbak/20140610allbackup
$ cd /oracle/flash_recovery_area/BOSS/archivelog/2014_06_10/
$ rm -rf *
（2）查看数据库的信息
SQL> select tablespace_name,status from dba_tablespaces;
TABLESPACE_NAME STATUS
------------------------------ ---------
SYSTEM ONLINE
UNDOTBS1 ONLINE
SYSAUX ONLINE
TEMP ONLINE
USERS ONLINE
EXAMPLE ONLINE
TESTTBS01 ONLINE
TESTTBS02 OFFLINE
TESTTBS03 READ ONLY
SQL> select table_name,status,tablespace_name from user_tables where tablespace_name like ‘TESTTBS%‘;
TABLE_NAME STATUS TABLESPACE_NAME
------------------------------ -------- ------------------------------
TEST01 VALID TESTTBS01
BOSS_NEW_TEST VALID TESTTBS01
SQL> select
2 ts.name "表空间名"
3 , df.file# "文件号"
4 , df.checkpoint_change# "检查点"
5 , df.name "文件名"
6 from v$tablespace ts,v$datafile df
7 where ts.ts#=df.ts#
8 order by df.file#;

（3）备份控制文件的trace文件
SQL> alter database backup controlfile to trace as ‘/oradata/bossbak/20140610allbackup/control1.trace‘ noresetlogs;
SQL> alter database backup controlfile to trace as ‘/oradata/bossbak/20140610allbackup/control2.trace‘;
SQL> alter database backup controlfile to trace as ‘/oradata/bossbak/20140610allbackup/control3.trace‘ resetlogs;
（4）创建表空间testtbs04，在表空间testtbs04创建表test02，然后直接shutdown abort
SQL>
create tablespace testtbs04
datafile ‘/oracle/oradata/boss/testtbs04_01.dbf‘ size 10m
autoextend on next 1m maxsize unlimited
logging
extent management local autoallocate
blocksize 8k
segment space management auto
flashback on;
Tablespace created.
SQL> create table test02 (id number, name varchar2(30)) tablespace testtbs04;
SQL> insert into test02 values(1,‘nnnnn‘);
SQL> insert into test02 values(2,‘mmmmm‘);
SQL> commit;
（5）删除所有控制文件
$ rm -rf *.ctl
SQL> shutdown abort;
ORACLE instance shut down.
SQL> startup open;
ORA-00205: error in identifying control file, check alert log for more info
（6）编辑trace文件
$ cp -rf control1.trace control.trace
