快速解決IMP中的ORA-00959
用IMP向測試庫導入DMP時，又遇到了ORA-00959表空間不存在的問題。
一般的解決方法：
1.先建表，在導入dmp時加ignore=y 的參數。
2.新建對應的表空間
3.使用expdp從新導出，在impdp時用REMAP_TABLESPACE
無論用那種方法都比較麻煩，都需要耗費一定的工作量。如果在oracle10g中，
採用重命名錶空間的方法,可以快速解決這個問題。
SQL> alter tablespace &old_tbsname rename to &new_tbs_name;
如當前用戶默認的表空間爲TEST,現在改爲需要的表空間YWDBS
SQL> alter tablespace TEST rename to YWDBS;

ORA-00959: tablespace 'YWDBS' does not exist

SQL> alter tablespace TEST rename to YWDBS;
重命名錶空間後，會在alert.log中看到如下信息：
Tablespace 'TEST' is renamed to 'YWDBS'.
Completed: alter tablespace TEST rename to YWDBS
重命名錶空間後，dmp可以順利導入
/oracle$imp TEST/TEST file=dev_bak_20110702.dmp tables=PRPDRISK statistics=none

爲了管理上的規範，在導入成功後可以在將表空間名該回去。
IMP中的ORA-00959一般發生在有CLOB字段的表上。
