expdp/impdp操作报错信息如下：
ORA-31626: job does not exist
ORA-31638: cannot attach to job SYS_EXPORT_TABLE_01 for user SYS
ORA-06512: at "SYS.DBMS_SYS_ERROR", line 95

ORA-39077: unable to subscribe agent KUPC$A_1_191136568928000 to queue "KUPC$C_1_20140807191136"
ORA-06512: at "SYS.DBMS_SYS_ERROR", line 95
ORA-06512: at "SYS.KUPC$QUE_INT", line 250
ORA-06502: PL/SQL: numeric or value error: character string buffer too small
根据报错信息初步分析，可能是datapump组件中sequence数值大于6位数或sequence失效导致。参考mos 文档1550344.1分析，此错误由oracle Bug 16473783 导致,在Oracle 12.2版本中被修复，如果执行脚本重新安装datapump组件可能会引起其它问题。
错误模拟
1.测试导出操作sequence值是否会增加
1.查看datapump组件包含的sequence
SQL> select OBJECT_NAME,OBJECT_TYPE,STATUS from all_objects where owner='SYS' and object_name like '%DATAPUMP%' and object_type='SEQUENCE';
OBJECT_NAME OBJECT_TYPE STATUS
------------------------------ ------------------- -------
AQ$_KUPC$DATAPUMP_QUETAB_N SEQUENCE VALID
AQ$_KUPC$DATAPUMP_QUETAB_1_N SEQUENCE VALID
2.查看两个sequence的值
SQL> select AQ$_KUPC$DATAPUMP_QUETAB_N.nextval from dual;
NEXTVAL
----------
1
SQL> select AQ$_KUPC$DATAPUMP_QUETAB_1_N.nextval from dual;
NEXTVAL
----------
361
3.执行导出
[oracle@ENMOEDU ~]$ expdp \'/ as sysdba\' directory=MY_DIR dumpfile=test.dmp tables=test.T_TASKDONE
4.查看sequence值
SQL> select AQ$_KUPC$DATAPUMP_QUETAB_N.nextval from dual;
NEXTVAL
----------
2
SQL> select AQ$_KUPC$DATAPUMP_QUETAB_1_N.nextval from dual;
NEXTVAL
----------
368
说明：导出操作datapump组件中的sequence值会增加
2.测试sequence值超过6位数是否出现此错误
1.通过Increment By来实现修改初始值。序列名称是`js
AQ$_KUPC$DATAPUMP_QUETAB_1_N，初始值是368，而现在要设置初始值为999999，Increment By值为:999619(999999-380)
SQL> Alter Sequence AQ$_KUPC$DATAPUMP_QUETAB_1_N Increment By 999619;
Sequence altered.
SQL> Select AQ$_KUPC$DATAPUMP_QUETAB_1_N.NextVal From Dual;
NEXTVAL
999987
SQL> Alter Sequence AQ$_KUPC$DATAPUMP_QUETAB_1_N Increment By 7;
Sequence altered.
SQL> Select AQ$_KUPC$DATAPUMP_QUETAB_1_N.NextVal From Dual;
NEXTVAL
999994
2.执行expdp导出操作查看是否报错
[oracle@ENMOEDU ~]$ expdp '/ as sysdba' directory=MY_DIR dumpfile=test.dmp logfile=test.log tables=test.T_TASKDONE

手动修复
1.重建sequence
1.重建sequence使用cycle参数限制最大值不超过6位数SQL> drop sequence AQ$_KUPC$DATAPUMP_QUETAB_1_N ;
Sequence dropped.
SQL> create sequence AQ$_KUPC$DATAPUMP_QUETAB_1_N minvalue 1 maxvalue 999999 start with 1 increment by 1 cache 20 cycle;
Sequence created.
2.验证sequence
1.验证sequence值超过6位时是否报错
SQL> drop sequence AQ$_KUPC$DATAPUMP_QUETAB_1_N;
Sequence dropped.
SQL> create sequence AQ$_KUPC$DATAPUMP_QUETAB_1_N minvalue 1 maxvalue 999999 start with 999997 increment by 1 cache 20 cycle;
Sequence created.
SQL> select AQ$_KUPC$DATAPUMP_QUETAB_1_N.nextval from dual;

MOS解决方案分析
MOS文档1550344.1提供的解决方案
SOLUTION
To address the issue, use any of below alternatives:
o Apply interim Patch 16928674 for the generic platform if available for your Oracle version.
- OR -
- As a workround, execute next scripts to recreate the datapump objects:
@$ORACLE_HOME/rdbms/admin/catdph.sql
@$ORACLE_HOME/rdbms/admin/prvtdtde.plb
@$ORACLE_HOME/rdbms/admin/catdpb.sql
@$ORACLE_HOME/rdbms/admin/dbmspump.sql
@$ORACLE_HOME/rdbms/admin/utlrp.sql
Please refer to
Note 16473783.8 - Bug 16473783 - expdp encounters ORA-39077 and ORA-31638 - withdrawn
Generally speaking, we can recreate the datapump objects in 11g by calling;
1. Catproc.sqlSQL> @$ORACLE_HOME/rdbms/admin/catproc.sql
2. To recompile invalid objects, if anySQL> @$ORACLE_HOME/rdbms/admin/utlrp.sql
This is described in
Note 430221.1 - How To Reload Datapump Utility EXPDP/IMPDP
- OR -
- As an alternative to a re-installation of datapump, which would need an instance shutdown/restart, you could recreate the queue table, e.g:
connect / as sysdba
exec dbms_aqadm.drop_queue_table(queue_table => 'SYS.KUPC$DATAPUMP_QUETAB', force => TRUE);
dbms_aqadm.create_queue_table(
queue_table => 'SYS.KUPC$DATAPUMP_QUETAB',
multiple_consumers => TRUE,
queue_payload_type => 'SYS.KUPC$_MESSAGE',
comment => 'DataPump Queue Table',
compatible => '8.1.3',
storage_clause=>'TABLESPACE SYSAUX');
Note that this will cause any running Data Pump jobs on the instance to fail with queue errors. However, they should be restartable.
分析：
1. 打Patch 16928674可以修复此bug，可以回退，不用停机风险小。
2. 执行如下脚本，但此方法会引起其它问题，被官方撤回。
@$ORACLE_HOME/rdbms/admin/catdph.sql
@$ORACLE_HOME/rdbms/admin/prvtdtde.plb
@$ORACLE_HOME/rdbms/admin/catdpb.sql
@$ORACLE_HOME/rdbms/admin/dbmspump.sql
@$ORACLE_HOME/rdbms/admin/utlrp.sql
或者
@$ORACLE_HOME/rdbms/admin/catproc.sql
@$ORACLE_HOME/rdbms/admin/utlrp.sql
3. 执行存储过程重新安装datapump组件，需要重启实例。
connect / as sysdba
exec dbms_aqadm.drop_queue_table(queue_table => 'SYS.KUPC$DATAPUMP_QUETAB', force => TRUE);
dbms_aqadm.create_queue_table(
queue_table => 'SYS.KUPC$DATAPUMP_QUETAB',
multiple_consumers => TRUE,
queue_payload_type => 'SYS.KUPC$_MESSAGE',
comment => 'DataPump Queue Table',
compatible => '8.1.3',
storage_clause=>'TABLESPACE SYSAUX');
验证打path 16928674修复bug
1.错误再现
1.将sequence值设置为999987
SQL> select AQ$_KUPC$DATAPUMP_QUETAB_1_N.nextval from dual;
NEXTVAL
321
SQL> Alter Sequence AQ$_KUPC$DATAPUMP_QUETAB_1_N Increment By 999666;
Sequence altered.
SQL> select AQ$_KUPC$DATAPUMP_QUETAB_1_N.nextval from dual;
NEXTVAL
999987
SQL> Alter Sequence AQ$_KUPC$DATAPUMP_QUETAB_1_N Increment By 1;
Sequence altered.
2.执行expdp导出

说明：安装patch后在执行expdp和impdp操作前会验证sequece，如果值大于1000000时，sequence会自动重建。
