首先这种方法不能恢复你误删除的数据,只是一种能让数据库正常启动的方案。

由于误操作删除了oracle数据库的dbf文件,启动数据库的时候报错

SQL> startup pfile=’/ytxt/oracle/product/10.2.0/db_1/dbs/initshutu.ora’;
ORACLE instance started.

Total System Global Area 3290345472 bytes
Fixed Size    2217832 bytes
Variable Size 2332035224 bytes
Database Buffers  939524096 bytes
Redo Buffers   16568320 bytes
Database mounted.
ORA-01157: cannot identify/lock data file 5 - see DBWR trace file
ORA-01110: data file 5: ’/ytxt/oracle/oradata/shutu/TYBOOKDB.dbf’
蛋疼,无奈就找解决办法。

执行以下步骤即可解决:

SQL> shutdown immediate;
ORA-01109: database not open
Database dismounted.
ORACLE instance shut down.
启动mount模式,由于本机器有点问题所有startup mount起不来,一般都是可以的,所以不只能用下面的命令起来
SQL> startup mount;
ORA-00119: invalid specification for system parameter LOCAL_LISTENER
ORA-00130: invalid listener address ’(ADDRESS=(PROTOCOL=TCP)(HOST=sc-orc-1.tylib.com)(PORT=1521))’

SQL>  startup pfile=’/ytxt/oracle/product/10.2.0/db_1/dbs/initshutu.ora’ mount;
ORACLE instance started.

Total System Global Area 3290345472 bytes
Fixed Size    2217832 bytes
Variable Size 2332035224 bytes
Database Buffers  939524096 bytes
Redo Buffers   16568320 bytes
Database mounted.
SQL> alter database datafile  ’/ytxt/oracle/oradata/shutu/TYBOOKDB.dbf’ offline drop;

Database altered.

SQL> alter database open;

Database altered.

停止数据库,然后启动数据库看看成功没有:

SQL> shutdown immediate;
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL> startup  pfile=’/ytxt/oracle/product/10.2.0/db_1/dbs/initshutu.ora’;
ORACLE instance started.

Total System Global Area 3290345472 bytes
Fixed Size    2217832 bytes
Variable Size 2332035224 bytes
Database Buffers  939524096 bytes
Redo Buffers   16568320 bytes
Database mounted.
Database opened.
完全没问题。此问题已解决。
