[oracle@ccdevsvr oracle]$

数据库是否归档模式?

在mount状态:

归档的话:

SQL>alter database datafile 'I:\ORADATA\EXAMORA\TEST01.DBF' offline;

非归档的话:

SQL>alter database datafile 'I:\ORADATA\EXAMORA\TEST01.DBF' offline drop;

然后在

SQL>alter database open;

[oracle@ccdevsvr root]$ cd /home/oracle

[oracle@ccdevsvr oracle]$ ll *.dbf

-rwxrwxrwx 1 oracle dba 209723392 Nov 29 11:47 iwbx_wmindx.dbf
