ORA-39012: Client detached 没有成功启动task，不会进行imp的任何操作
impdp出现连接信息后，会开始执行truncate table 后import动作，这个时候几十abort /stop，在执行的表依旧会完成import，可以参考log里面的信息。 abort /stop只对未执行的table 生效，v$session中可以查看session 信息。
impdp中途取消要小心，很容易数据重复导入了。

Summary
When using DataPump API the following errors are received:
ORA-39232: invalid remap function: NewUDFValExt
ORA-39012: Client detached before the job started.
Please note that the function name will be replaced with your defined function name. In our example it is 'NewUDFValExt'.
Solution
The Bug 8751620 (closed as 'Not a bug') was filed for this case and development has informed that this is an expected behavior when it comes to Datapump API being called inside PL/SQL block.
Datapump API expects the function name in UPPER case when this is called inside PL/SQL block. In this case the function name (NewUDFValExt) is passed in mixed case letters. There are no issues when the function name ('NewUDFValExt') is passed in UPPER case characters, e.g:
DBMS_DATAPUMP.data_remap (h1, 'COLUMN_FUNCTION', 'UDF_VAL_TEST', 'UDF_VAL_EXT', 'NEWUDFVALEXT', 'TEST');
Cause
Test to reproduce:
connect / as sysdba
create user test identified by <PASSWORD>;
grant connect, resource,dba to test;
CREATE or replace DIRECTORY DMPDIR AS '/tmp';
GRANT READ, WRITE ON DIRECTORY DMPDIR TO test;
connect test/<PASSWORD>
create table UDF_VAL_TEST
(
UDF_VAL_ID NUMBER(10) not null,
UDF_VAL_EXT NVARCHAR2(2000)
);
Insert into UDF_VAL_TEST(UDF_VAL_ID, UDF_VAL_EXT) values (1, 'val1');
Insert into UDF_VAL_TEST(UDF_VAL_ID, UDF_VAL_EXT) values (2, 'val2');
Insert into UDF_VAL_TEST(UDF_VAL_ID) values (3);
Insert into UDF_VAL_TEST(UDF_VAL_ID,UDF_VAL_EXT) values (4, 'val4');
Insert into UDF_VAL_TEST(UDF_VAL_ID) values (5);
commit;
DECLARE
h1 NUMBER;
begin
h1 := DBMS_DATAPUMP.open ('EXPORT', 'TABLE', NULL, 'MY_EXPORT_JOB1', 'COMPATIBLE');
-- specify dump file
DBMS_DATAPUMP.add_file (h1, 'UDFVAL1.dmp', 'DMPDIR', '10M', DBMS_DATAPUMP.KU$_FILE_TYPE_DUMP_FILE);
-- specify log file
DBMS_DATAPUMP.add_file (h1, 'Export1.log', 'DMPDIR', '10M', DBMS_DATAPUMP.KU$_FILE_TYPE_LOG_FILE);
DBMS_DATAPUMP.metadata_filter (h1, 'NAME_EXPR', 'IN(''UDF_VAL_TEST'')');
DBMS_DATAPUMP.data_remap (h1, 'COLUMN_FUNCTION', 'UDF_VAL_TEST', 'UDF_VAL_EXT', 'NewUDFValExt', 'TEST');
DBMS_DATAPUMP.start_job(h1);
