Oracle重建控制文件的实例教程(2)-木庄网络博客

3.1 备份控制文件到trace

startup mount
alter database backup controlfile to trace;
oradebug setmypid
oradebug tracefile_name

3.2 启动数据库到nomount状态

shutdown abort
startup nomount;

3.3 确认重建控制文件的语句

vi control.sql
CREATE CONTROLFILE REUSE DATABASE "CXYWDB" NORESETLOGS FORCE LOGGING ARCHIVELOG
 MAXLOGFILES 16
 MAXLOGMEMBERS 3
 MAXDATAFILES 100
 MAXINSTANCES 8
 MAXLOGHISTORY 292
LOGFILE
 GROUP 5 '/oradata2/cxywdb/redo11.log' SIZE 50M,
 GROUP 6 '/oradata2/cxywdb/redo12.log' SIZE 50M,
 GROUP 7 '/oradata2/cxywdb/redo13.log' SIZE 50M
-- STANDBY LOGFILE
DATAFILE
 '/oradata/cxywdb/system01.dbf',
 '/oradata/cxywdb/undotbs01.dbf',
 '/oradata/cxywdb/sysaux01.dbf',
 '/oradata/cxywdb/users01.dbf',
 '/oradata/cxywdb/alfred01.dbf',
 '/oradata/cxywdb/alfred02.dbf',
 '/oradata/cxywdb/alfred03.dbf',
 '/oradata/cxywdb/alfred04.dbf',
 '/oradata/cxywdb/alfred05.dbf',
 '/oradata/cxywdb/dbs_i_alfred01.dbf'
CHARACTER SET ZHS16GBK
;

3.4 恢复并打开数据库

SQL> recover database;
Media recovery complete.
SQL> alter database open;
Database altered.

附：实际解决过程如下：

SQL> shutdown abort  
ORACLE instance shut down.
SQL> startup mount

ORACLE instance started.

Total System Global Area 599785472 bytes
Fixed Size     2098112 bytes
Variable Size    218106944 bytes
Database Buffers   373293056 bytes
Redo Buffers    6287360 bytes
Database mounted.
SQL> alter database backup controlfile to trace;

Database altered.

SQL> oradebug setmypid
Statement processed.
SQL> oradebug tracefile_name
/s01/oracle/admin/cxywdb/udump/cxywdb_ora_3983.trc
SQL> shutdown abort
ORACLE instance shut down.
SQL> startup nomount;
ORACLE instance started.
