6.将表空间jytest从目标数据库中删除,但保留数据文件
SQL> drop tablespace jytest including contents;
Tablespace dropped.
7.将原数据库中的表空间jytest联机,继续向表t1插入记录
SQL> alter tablespace jytest read write;
Tablespace altered.
SQL> insert into t1 select * from t1;
insert into t1 select * from t1
*
ERROR at line 1:
ORA-01653: unable to extend table JYTEST.T1 by 128 in tablespace JYTEST
由于表空间jytest没有空间了，如是向表这僮jytest增加一个数据文件jytest02.dbf来增加表空间
SQL> alter tablespace jytest add datafile '/u01/app/oracle/oradata/jytest/jytest02.dbf' size 5M;
Tablespace altered.
SQL> insert into t1 select * from t1;
12856 rows created.
SQL> commit;
Commit complete.
SQL> select count(*) from t1;

8.如果自上次增量备份以后原数据库表空间jytest增加了新的数据文件，因此执行以下命令来为新增加的数据文件创建镜像副本。
SQL> alter tablespace jytest read only;
Tablespace altered.
SQL> select file#,name from v$datafile;
FILE# NAME

9.对原数据库执行RMAN增量备份并使用目标数据库文件目录中的数据文件与其合并，因些创建一组
新的数据文件
