oracle数据泵导入遭遇bug记录

下午收到了一个导数据的需求，一张表，20多万数据，小case，却遇到了问题。

关键报错：

ORA-39097 ORA-39065 ORA-01427 ORA-39126 ORA-06502 LPX-00225

导入语句：

impdp “‘/as sysdba'” directory=DATA_PUMP_DIR dumpfile=NCHATTAG1.dmp logfile=20180821.log

log如下：

可以看到dw进程在处理表的统计信息时，在处理直方图信息的时候出现了错误，在源端查询表上确实有直方图。这种内部处理过程出现无法正确处理的情况，可以认为是oracle的bug。解决办法也简单，绕过统计信息即可：

impdp “‘/as sysdba'” directory=DATA_PUMP_DIR dumpfile=NCHATTAG1.dmp logfile=20180821.log table_exists_action=replace EXCLUDE=STATISTICS

无报错成功导入。

手动收集统计信息：

oracle@bd-dev-oracle-104:/opt/app/oracle/diag/rdbms/bdcfg/BDCFG/trace$ora ant NCHATTAG1 message

n=============Tue Aug 21 16:54:43 CST 2018===================n

exec DBMS_STATS.GATHER_TABLE_STATS(ownname=>’NCHATTAG1′,tabname=>’message’,estimate_percent=>10,no_invalidate=>false,cascade=>true,degree => 10);

Can you confirm?[y/n]

事后去mos上搜索了一下，可以参考文档 ID 878626.1
