【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
