ORA-20000的解决过程

Posted 2020-07-03 头痛不头痛

   今天在用impdp导数据时出现卡住的现象，开始我以为是数据量过大导致的，过了两个小时还是卡住，看警告日志得到下面的错误信息：

GATHER_STATS_JOB encountered errors.  Check the trace file.
Errors in file d:\app\zy\diag\rdbms\mydev\mydev\trace\mydev_j000_265128.trc:
ORA-20000: index "CWUSER"."PK_ACCARTICLECODEMAPPING"  or partition of such index is in unusable state

进入cwuser查看该index的状态

SQL> select status from dba_indexes where index_name=‘PK_ACCARTICLECODEMAPPING‘;
 
STATUS
--------
N/A

重建该索引

SQL> alter index PK_ACCARTICLECODEMAPPING rebuild online;
 
Index altered
