表空间备份与恢复次要针关于大型数据库中，某个表空间数据变革十分大，增长速度十分快的情况。表空间的备份实现脚本：
run {
allocate channel d1 type disk;
backup tablespace "TEST","USERS" format ’d:\backup\tb_%d_%s_%p_%t’;
release channel d1;
恢复时，若是用户是要恢复被删除的表空间中的表或视图，或者是利用者用drop tablespace一般号令删除了表空间，此时控造文件中记录的数据库构造也跟着做了改动，此时只能用不完全恢复，让数据库恢复到以前的一个时间点或SCN。
先恢复控造文件，再恢复表空间。 自学编程网
Shutdown abort;
Startup nomount;
run {
Allocate channel d1 type disk;
Restore controlfile from ‘d:\backup\CTL_TEST_0_1_6555’;
Release channel d1 ;
Alter database open; //要为翻开形态
set until time "TO_DATE(’08/08/2007 10:50:00’,’MM/DD/YYYY HH24:MI:SS’)";
sql ’alter tablespace TEST, USERS offline immediate’;
allocate channel d1 type disk;
restore tablespace
TEST, USERS;
recover tablespace
TEST, USERS;
release channel d1;
sql ’alter tablespace TEST, USERS online’;
留意：After you perform TSPITR on a tablespace, you cannot use backups of that tablespace
from before the TSPITR was completed and the tablespace put back on line。
If you
start using the recovered tablespaces without taking a backup, you are running your
database without a usable backup of those tablespaces。
For this example, the users。
