IMPDP時出現ORA-39083：Object type PROCACT_SCHEMA failed to create with error

在使用IMPDP對數據庫按照Schema進行導入數據時，出現了奇怪的錯誤，數據庫版本11.2.0.3.0。

IMPDP導入命令如下。

impdp system/tplink directory=dump_dir dumpfile=tpqms.dmp remap_schema=tpqms:tpqms remap_tablespace=TPQMS_DATA:TPQMS_DATA table_exists_action=replace  transform=segment_attributes:n

錯誤提示如下。

ORA-39083: Object type PROCACT_SCHEMA failed to create with error:
ORA-31625: Schema TPQMS is needed to import this object, but is unaccessible
ORA-01031: insufficient privileges
Failing sql is:
BEGIN 
sys.dbms_logrep_imp.instantiate_schema(schema_name=>SYS_CONTEXT('USERENV','CURRENT_SCHEMA'), export_db_name=>'IQCPROD', inst_scn=>'108444820');COMMIT; END; 
Processing object type SCHEMA_EXPORT/SEQUENCE/SEQUENCE
......
ORA-39083: Object type INDEX failed to create with error:
ORA-31625: Schema TPQMS is needed to import this object, but is unaccessible
ORA-01031: insufficient privileges
Failing sql is:
CREATE INDEX "TPQMS"."REPORT_TPL_ITEM_HID" ON "TPQMS"."REPORT_TPL_ITEM" ("TPL_ID") 
......

根據提示，我對system和tpqms賬戶賦予了權限。

SQL> grant create user to system;
SQL> grant create any index to system;

SQL> grant create user to tpqms;
SQL> grant create any index to tpqms;

然而還是有上述的異常。

於是搜索了一些解決方法，提示是用戶缺少IMP_FULL_DATABASE權限，於是我將該權限賦予給system和tpqms用戶。

SQL> grant IMP_FULL_DATABASE to system;
SQL> grant IMP_FULL_DATABASE to tpqms;

仍有如上異常。

最後在Oracle Support上找到了一篇類似的解決方法，針對數據庫12C版本的解決方法，試用一下該方法，問題解決。

在導入時賦予become user權限給system用戶，導入結束後回收該權限即可。

SQL> grant become user to system;

SQL> revoke become user from system;

最後，IMPDP導入正常。
