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===================
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
