[20121105]重建控制文件少一个数据文件的情况.txt

我的测试数据库经常做各种测试,resetlogs很多次,产生很多incarnation.今天想通过重建控制文件来清除这些信息.

我的控制文件的脚本是以前建立的,少包括一个数据文件.自己就拿这个做一个测试看看.

建立控制文件少包括'/u01/app/oracle11g/oradata/test/test01.dbf'

STARTUP NOMOUNT

CREATE CONTROLFILE REUSE DATABASE "TEST" NORESETLOGS  ARCHIVELOG

    MAXLOGFILES 16

    MAXLOGMEMBERS 3

    MAXDATAFILES 1600

    MAXINSTANCES 8

    MAXLOGHISTORY 292

LOGFILE

  GROUP 1 '/u01/app/oracle11g/oradata/test/redo01.log'  SIZE 50M BLOCKSIZE 512,

  GROUP 2 '/u01/app/oracle11g/oradata/test/redo02.log'  SIZE 50M BLOCKSIZE 512,

  GROUP 3 '/u01/app/oracle11g/oradata/test/redo03.log'  SIZE 50M BLOCKSIZE 512

-- STANDBY LOGFILE

DATAFILE

  '/u01/app/oracle11g/oradata/test/system01.dbf',

  '/u01/app/oracle11g/oradata/test/sysaux01.dbf',

  '/u01/app/oracle11g/oradata/test/undotbs01.dbf',

  '/u01/app/oracle11g/oradata/test/users01.dbf',

  '/u01/app/oracle11g/oradata/test/example01.dbf',

  '/u01/app/oracle11g/oradata/test/rman01.dbf',

  '/u01/app/oracle11g/oradata/test/tools01.dbf'

--  '/u01/app/oracle11g/oradata/test/test01.dbf'

;

执行以上后打开正常:

Database altered.

--建立临时文件.

ls: /u01/app/oracle11g/product/11.2.0/db_1/dbs/MISSING00008: No such file or directory

2.仅仅需要改名到原来的位置就ok了.

SQL> alter database rename file '/u01/app/oracle11g/product/11.2.0/db_1/dbs/MISSING00008' to '/u01/app/oracle11g/oradata/test/test01.dbf';

Database altered.

SQL> recover datafile 8;

SQL> select * from V$RECOVER_FILE;

--OK,恢复完成!

3.测试:

SQL> select tablespace_name from dba_tables where wner='SCOTT' and table_name='DEPT1';

TABLESPACE_NAME

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

TEST

SQL> select * from scott.dept1;

    DEPTNO DNAME          LOC

        10 ACCOUNTING     NEW YORK

        20 RESEARCH       DALLAS

        30 SALES          CHICAGO

        40 OPERATIONS     BOSTON

--OK,正常!

RMAN> list incarnation ;
