環境
Red Hat Enterprise Linux Server release 5.8 (Tikanga)
ORACLE Release 11.2.0.3.0 Production
我用expdp,impdp復制一個shema，在impdp導入的時候報錯
ORA-39083: Object type TYPE failed to create with error:
ORA-02304: invalid object identifier literal
Failing sql is:
CREATE TYPE "GENIDCDEV2"."ARRAY_TYPE2" OID '0367306C82464BF1E0534E092D0A4AB5' is array(48) of varchar2(255)
查看官方文檔的impdp章節，搜索OID,發現了如下有用的內容
查看impdp help=y 可以使用一個參數：transform
TRANSFORM
Enables you to alter object creation DDL for objects being imported.
OID - If the value is specified as n, the assignment of the exported OID during the
creation of object tables and types is inhibited. Instead, a new OID is assigned.
This can be useful for cloning schemas, but does not affect referenced objects. The
default value is y.
這個參數默認是Y，如果改成N，那么導入的時候會把各個對象重新賦予新的OID。
transform=oid:n
這樣，再用impdp導入的時候就不會出現
ORA-39083，ORA-02304
注意：exp/imp不支持oid轉換，又是一個使用數據泵的優勢。
因此我想到了兩種方法可以解決問題
1.用下面impdp語句重新導入
impdp system/'*****' directory=dir_lisx REMAP_SCHEMA=WMSUAT:GENIDCDEV2 dumpfile=wmsuat20150304.dump include=TYPE transform=oid:n logfile=impdp_wmsuat20150304_2.log

Processing object type SCHEMA_EXPORT/TYPE/TYPE_SPEC
Job "SYSTEM"."SYS_IMPORT_FULL_01" successfully completed at 14:55:45
2.手工重建剛才導入失敗的type
核查type的ddl語句
SELECT dbms_metadata.get_ddl('TYPE','ARRAY_TYPE2','WMSUAT') from dual ;
CREATE OR REPLACE TYPE "WMSUAT"."ARRAY_TYPE2" is array(48) of varchar2(255) ;
記得重新編譯一下新clone的schema
EXEC DBMS_UTILITY.compile_schema(schema => 'GENIDCDEV2');
