1.创建实例
oradim (命令行下包含多种可选项,可自行选择)
oradim -new -sid maxld
在已有数据库运行的情况下需要注意设置环境变量
c:set oracle_sid=demo
c:sqlplus / as sysdba
2.创建或修改初始化参数文件
手头有其他数据库的情况下
sql>create pfile from spfile
此文件在dbhome_1下的database中
根据实际情况修改pfile文件
替换SID等
例如
orcl.__db_cache_size=205520896 替换为 demo.__db_cache_size=205520896
3.创建相应的目录结构
*.audit_file_dest='C:appAdministratoradmindemoadump'
*.control_files='C:appAdministratororadatademocontrol01.ctl',
'C:appAdministratorflash_recovery_areademocontrol02.ctl'
4.启动实例
sql>startup nomount
5.拷贝修改pfile,准备控制文件。
cp /oracle10/oradata/ora10/control01.ctl .
SQL> startup mount pfile='/tmp/pfile10.ora';
ORACLE instance started.
6. 恢复数据库。
run {
ALLOCATE CHANNEL ch0 TYPE disk;
set newname for datafile 1 to 'C:appAdministratororadatasystem01.dbf';
set newname for datafile 2 to 'C:appAdministratororadatasysaux01.dbf';
set newname for datafile 3 to 'C:appAdministratororadataundotbs01.dbf';
set newname for datafile 4 to 'C:appAdministratororadatausers01.dbf';
set newname for datafile 5 to 'C:appAdministratororadataMAXIMO_DATA.dbf';
set newname for datafile 6 to 'C:appAdministratororadataMAXIMO_index.dbf';
set newname for datafile 7 to 'C:appAdministratororadataMAXIMO_DATA02.dbf';
set newname for datafile 8 to 'C:appAdministratororadataMAXIMO_index02.dbf';
set newname for tempfile 1 to 'C:appAdministratororadatatemp01.dbf';
set newname for tempfile 2 to 'C:appAdministratororadataMAXIMO_temp.dbf';
restore database;
switch datafile all;
switch tempfile all;
release channel ch0;
}
recover database;
