非归档模式还原：

startup force nomount:

restore controlfile;

alter database mount;

restore database;

recover database noredo;

alter database open resetlogs;

块追踪增加增量备份速度(已废弃)

alter database enable block change tracking using file ‘xxx’;

alter database disable block change tracking;

select * from v$block_change_tracking;
