IMPDP时出现ORA-39083：Object type PROCACT_SCHEMA failed to create with error

在使用IMPDP对数据库按照Schema进行导入数据时，出现了奇怪的错误，数据库版本11.2.0.3.0。

IMPDP导入命令如下。

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

错误提示如下。

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") 
......

根据提示，我对system和tpqms账户赋予了权限。

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;

然而还是有上述的异常。

于是搜索了一些解决方法，提示是用户缺少IMP_FULL_DATABASE权限，于是我将该权限赋予给system和tpqms用户。

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

仍有如上异常。

最后在Oracle Support上找到了一篇类似的解决方法，针对数据库12C版本的解决方法，试用一下该方法，问题解决。

在导入时赋予become user权限给system用户，导入结束后回收该权限即可。

SQL> grant become user to system;

SQL> revoke become user from system;

最后，IMPDP导入正常。
