丢失所有控制文件，还原所有数据文件，不还原控制文件，recoverd-mysql教程

说明：创建表test03，切换日志，创建表test04，切换日志，删除所有数据文件，还原备份的所有数据文件，不需要还原控制文件；test03的归档日志没有丢失，test04的归档日志丢失，不能恢复test04 1、数据库所有控制文件丢失 2、还原备份之前的控制文件，数据文

说明：创建表test03，切换日志，创建表test04，切换日志，删除所有数据文件，还原备份的所有数据文件，不需要还原控制文件；test03的归档日志没有丢失，test04的归档日志丢失，不能恢复test04
1、数据库所有控制文件丢失 2、还原备份之前的控制文件，数据文件没做还原 3、until cancel using bakup controlfile跑部分归档日志
（1）一致性的全备
SQL> shutdown immediate;

# mkdir -p /oradata/bossbak/20140609allbackup
# cp -rf $ORACLE_BASE/oradata/boss/*.dbf /oradata/bossbak/20140609allbackup
# cp -rf $ORACLE_BASE/oradata/boss/*.ctl /oradata/bossbak/20140609allbackup
# cp -rf $ORACLE_HOME/dbs/spfileboss.ora /oradata/bossbak/20140609
# cd /oracle/flash_recovery_area/BOSS/archivelog/2014_06_09/
# 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

（3）创建表test03，插入数据
SQL> create table test03 (id number, name varchar2(30)) tablespace testtbs01;
SQL> insert into test03 values(1, '11111');
SQL> insert into test03 values(2,'22222');
SQL> insert into test03 values(3,'33333');
SQL> insert into test03 values(1, '11111');
SQL> insert into test03 values(2,'22222');
SQL> insert into test03 values(3,'33333');
SQL> commit;

（4）进行日志切换
SQL> alter system switch logfile;
SQL> select group#,members,sequence#,archived,status,first_change# from v$log;

GROUP# MEMBERS SEQUENCE# ARC STATUS FIRST_CHANGE#
---------- ---------- ---------- --- ---------------- -------------
1 1 2 YES INACTIVE 675131
2 1 4 NO CURRENT 700583
3 1 3 YES ACTIVE 699759
SQL> alter system switch logfile;
SQL> alter system switch logfile;

SQL> create table test04 (id number, name varchar2(30)) tablespace testtbs01;
SQL> insert into test04 values(1, '11111');
SQL> insert into test04 values(2,'22222');
SQL> insert into test04 values(3,'33333');
SQL> commit;

SQL> alter system switch logfile;
SQL> alter system switch logfile;
SQL> alter system switch logfile;

SQL> select group#,members,sequence#,archived,status,first_change# from v$log;

GROUP# MEMBERS SEQUENCE# ARC STATUS FIRST_CHANGE#
---------- ---------- ---------- --- ---------------- -------------
1 1 8 YES INACTIVE 704201
2 1 7 YES INACTIVE 704199
3 1 9 NO CURRENT 704204

（5）备份全备后所有的归档日志
# pwd
/oracle/flash_recovery_area/BOSS/archivelog/2014_06_09
# cp -rf *.arc /oradata/bossbak/20140609

（6）删除全部归档，删除全部数据文件
# rm -rf *.arc

（7）关闭数据库
SQL> shutdown abort;
ORACLE instance shut down.

SQL> startup open;
ORA-01157: cannot identify/lock data file 1 - see DBWR trace file
ORA-01110: data file 1: '/oracle/oradata/boss/system01.dbf'
（8）还原备份的数据文件，不需要恢复控制文件
$ cp -rf *.dbf /oracle/oradata/boss

SQL> col "文件名" for a40
SQL> set linesize 150
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 , df.status "在线状态"
7 , rf.error "恢复原因"
8 , rf.change# "系统变更号"
9 , rf.time
10 from v$tablespace ts,v$datafile df,v$recover_file rf
11 where ts.ts#=df.ts# and df.file#=rf.file#
12 order by df.file#;
#####最近一次数据库正常启动后的scn

（9）复制部分的归档日志，基于终止恢复
# cp -rf o1_mf_1_3_9sbbrfsx_.arc o1_mf_1_4_9sbbsn5j_.arc /oracle/flash_recovery_area/BOSS/archivelog/2014_06_09/
