【IMPDP】ORA-00959: tablespace 'YOUFEE_LOB' does not exist解决

【IMPDP】ORA-00959: tablespace 'YOUFEE_LOB' does not exist解决
 
今天用IMPDP基于SCHEMA导入数据库时,报错了:
 
[error]
ORA-39083: Object type TABLE failed tocreate with error:
ORA-00959: tablespace 'YOUFEE_LOB' does not exist
Failing sql is:
CREATE TABLE "YOUFEE"."DEPT"

 

因为表空间YOUFEE_LOB不存在导致DEPT表无法导入数据库
 
一般情况下,表会导入到和原来所在表空间名字相同的表空间下,如果target端数据库不存在这个表空间,就会导入到所属schema的默认表空间下。不会因为表空间的问题而报错。
而这里产生这个错误的原因是,DEPT这个表存在于两个表空间(例如有DEPT表有CLOB字段时,CLOB字段存在于另一个表空间)此时,如果target端没有CLOB字段所在的原同名表空间就会报错。
 
[solution]
1.      事先在target端建好CLOB字段所需的原名表空间
2.      事先在target端建好DEPT表结构,并在impdp导入时使用参数CONTENT=DATA_ONLY
3.      在使用impdp导入时,使用参数remap_Tablespace=YOUFEE_LOB:USERS,将本该存储到YOUFEE_LOB表空间下的数据库映射到已有的USERS表空间下
 
实验验证:
1.      创建两个表空间和一个用户
SQL> create tablespace youfeedatafile '/u01/app/oracle/oradata/BALLONTT/youfee.dbf'size 10m;
Tablespace created.

SQL> create tablespace youfee_lob datafile '/u01/app/oracle/oradata/BALLONTT/youfee_lob.dbf'size 10m;
Tablespace created.

SQL> create user youfee identified by oracle default tablespace youfee accountunlock;
User created.

SQL> grant resource,connect to youfee;
Grant succeeded.

SQL> conn youfee/oracle
Connected.
SQL> create table emp(id number,ename varchar2(10));
Table created.

SQL> insert into emp values(1,'cat');
 1 row created.
SQL> commit;
Commit complete.

SQL> create table dept(dept_id number,infoclob) lob(info) store as (tablespace youfee_lob);
Table created.

SQL> insert into dept values(1,'tiger');
1 row created.

SQL> commit;
Commit complete.

2.      导出youfee用户下的对象
[oracle@ballontt ~]$ expdp system/oracledirectory=dir_dmp dumpfile=youfee.dmp schemas=youfee logfile=youfee.log
[oracle@ballontt ~]$ ls
youfee.dmp youfee.log

3.      删除表emp,dept和存储clob字段的表空间YOUFEE_LOB
SQL> conn youfee/oracle
Connected.

SQL> drop table emp;
Table dropped.

SQL> drop table dept;
Table dropped.

SQL> conn / as sysdba
Connected.
SQL> drop tablespace youfee_lob includingcontents and datafiles;
Tablespace dropped.

 

 
4.      IMP导入数据库
[oracle@ballontt ~]$ impdp system/oracledirectory=dir_dmp dumpfile=youfee.dmp schemas=youfee logfile=youfee.log

[error]
ORA-39083: Object type TABLE failed tocreate with error:
ORA-00959: tablespace 'YOUFEE_LOB' does notexist
Failing sql is:
CREATE TABLE"YOUFEE"."DEPT"

 

可以看到,报了上述错误。
 
5.      解决方法之一(使用remap_tablespace参数)
[oracle@ballontt ~]$ impdp system/oracledirectory=dir_dmp dumpfile=youfee.dmp schemas=youfee logfile=youfee.log remap_tablespace=YOUFEE_LOB:youfee

Processing object typeSCHEMA_EXPORT/TABLE/TABLE_DATA
. . imported"YOUFEE"."DEPT"                            5.273 KB       1 rows
Job"SYSTEM"."SYS_IMPORT_SCHEMA_01" completed with 2 error(s)at 20:10:53

 

DEPT表被导入进去了
