丢失全部控制文件，noresetlogs重建控制文件，alter database open

測试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 "文件名称"

  6    from v$tablespace ts,v$datafile df

  7  where ts.ts#=df.ts#

  8  order by df.file#;

表空间名                           文件号     检查点 文件名称

------------------------------ ---------- ---------- ----------------------------------------

SYSTEM                                  1     708505 /oracle/oradata/boss/system01.dbf

UNDOTBS1                                2     708505 /oracle/oradata/boss/undotbs01.dbf

EXAMPLE                                 5     708505 /oracle/oradata/boss/example01.dbf

TESTTBS01                               6     708505 /oracle/oradata/boss/testtbs01_01.dbf

TESTTBS01                               7     708505 /oracle/oradata/boss/testtbs01_02.dbf

TESTTBS02                               8     652783 /oracle/oradata/boss/testtbs02_01.dbf

TESTTBS03                               9     652799 /oracle/oradata/boss/testtbs03_01.dbf

（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）删除全部控制文件

$ 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
