Oracle表空间数据文件丢失的恢复

ORA-01157: cannot identify/lock data file 10 - see DBWR trace file

ORA-01110: data file 10: '/home/oracle/oradata/ora10/xxt_mt_msg09.ora'

郁闷,居然出现了错误,看了当前目录居然这个文件不知道被谁删除了,我直接狂汗,通过千辛万苦找了解决的方法:

SQL> startup mount ;
SQL> alter database create datafile '/home/oracle/oradata/ora10/xxt_mt_msg09.ora';
SQL> set autorecovery on;
SQL> recover datafile '/home/oracle/oradata/ora10/xxt_mt_msg09.ora';
SQL> alter database datafile '/home/oracle/oradata/ora10/xxt_mt_msg09.ora' online;

SQL> alter tablespace XXT_mt_as_msg online;

SQL> alter database open;

现在再到当前的数据库文件目录发现这个xxt_mt_msg09.ora已经还原回来了,然后重新扩大了下表空间,这下又可以创建表了.
