DataPump遭遇ORA-06512&ORA-39080&ORA-01403错误案例

最近使用数据泵（DataPump)比较多，遇到了奇奇怪怪的问题，似乎Apply了补丁PSU 10.2.0.5.180717后，DataPump的问题就格外多。如下所示：

 

expdp system/xxx DIRECTORY=DUMPDIR DUMPFILE=xxxx.dmp TABLES=xxxx.xxxx  LOGFILE=expdp.log 

Export: Release 10.2.0.5.0 - 64bit Production on Monday, 19 August, 2019 9:52:07

ORA-31626: job does not exist

ORA-31637: cannot create job SYS_EXPORT_TABLE_01 for user SYSTEM

ORA-06512: at "SYS.DBMS_SYS_ERROR", line 95

ORA-06512: at "SYS.KUPV$FT_INT", line 672

ORA-39080: failed to create queues "" and "" for Data Pump job

ORA-06512: at "SYS.DBMS_SYS_ERROR", line 95

ORA-06512: at "SYS.KUPC$QUE_INT", line 1606

ORA-01403: no data found

 

遇到这个错误，最开始我以为是我之前遇到的是同一个问题“Expdp 导数错误 ORA-00832”，检查发现__streams_pool_size大小不为0

 

SQL> col name for a36;

SQL> col value for a10;

SQL> col idfefault for a10;

col ismod for a10;

col isadj for a10;

SQL> SELECT X.ksppinm      name       ,

       Y.ksppstvl     value      ,

       Y.ksppstdf     idfefault  ,

       DECODE(bitand(Y.ksppstvf,7), 1, 'MODIFIED', 4, 'SYSTEM_MOD', 'FALSE')  ismod,

       DECODE(bitand(Y.ksppstvf,2), 2, 'TRUE', 'FALSE')  isadj

FROM sys.x$ksppi  X,

     sys.x$ksppcv Y

WHERE X.inst_id = userenv('Instance') AND

      Y.inst_id = userenv('Instance') AND

      X.indx    = Y.indx              AND

      X.ksppinm LIKE '%_streams%'

ORDER BY translate(X.ksppinm, '_', ''); 

NAME                                 VALUE      IDFEFAULT  ISMOD      ISADJ

------------------------------------ ---------- ---------- ---------- ----------

__streams_pool_size                  33554432   FALSE      FALSE      FALSE

_memory_broker_shrink_streams_pool   900        TRUE       FALSE      FALSE

_disable_streams_pool_auto_tuning    FALSE      TRUE       FALSE      FALSE

_streams_pool_max_size               0          TRUE       FALSE      FALSE

 

 然后开启跟踪'1403 trace name errorstack level 3'，执行导出命名后，然后关闭跟踪'1403 trace name errorstack off'

 

SQL> alter system set events '1403 trace name errorstack level 3';

 

System altered.

 

run the expdp command

 

SQL> alter system set events '1403 trace name errorstack off';

 

System altered.

 

查看trace文件，如下截图所示，提示“ksedmp:internal or fatal error" ,搜索了一下metalink，发现还真有一模一样的错误

 

 

 

但是这个案例中，在验证表结构时，发现表不存在，所以必须reload the DataPump utility， reload the DataPump utility候就能正常的导入导出了。

 

 

SQL> analyze table kupc$datapump_quetab validate structure;

analyze table kupc$datapump_quetab validate structure

              *

ERROR at line 1:

ORA-00942: table or view does not exist

 

具体的官方文档如下所示：

 

DataPump Import Or Export (IMPDP/EXPDP) Fails With Errors ORA-31626 ORA-31637 (文档 ID 345198.1)

 

APPLIES TO:

Oracle Database - Enterprise Edition - Version 10.1.0.4 and later

SYMPTOMS

Trying to execute the DataPump export or import ends with errors like:

ORA-31626: job does not exist
ORA-31637: cannot create job SYS_EXPORT_FULL_01 for user SYSTEM
ORA-06512: at "SYS.DBMS_SYS_ERROR", line 95
ORA-06512: at "SYS.KUPV$FT_INT", line 601
ORA-39080: failed to create queues "" and "" for Data Pump job
ORA-06512: at "SYS.DBMS_SYS_ERROR", line 95
ORA-06512: at "SYS.KUPC$QUE_INT", line 1550
ORA-01403: no data found

You can also see errors like:

ORA-39006 - internal error
ORA-39065: unexpected master process exception in DISPATCH
ORA-01403: no data found
ORA-39097: Data pump job encountered unexpected error 100

CHANGES

 

CAUSE

Such errors typically happen in instances with incorrectly configured Advanced Queueing (AQ).

SOLUTION

To resolve the issue, follow the steps below:

1. Set the error stack 1403 event to know exactly which SQL is failing:

connect / as sysdba
alter system set events '1403 trace name errorstack level 3';

 

NOTE:
In databases that are heavy loaded, setting this event will produce many trace files. It is recommended to set this when the database is not intensively used.

Then re-run the DataPump export/import to reproduce the error and then disable the events.

alter system set events '1403 trace name errorstack off';

2. Once the trace file reveals the problematic SQL, check for the existence of table KUPC$DATAPUMP_QUETAB using DBA_OBJECTS.

3. If present, then run:

connect / as sysdba
analyze table kupc$datapump_quetab validate structure;

4. If not present or it errors out in step 3, then reload the DataPump utility as described in Note 430221.1.
