在手工更新統(tǒng)計信息時，報ORA-20005異常

SQL>exec dbms_stats.gather_table_stats('SYS','TEST');

BEGINdbms_stats.gather_table_stats('SYS','TEST'); END;

*

ERRORat line 1:

ORA-20005:object statistics are locked (stattype = ALL)

ORA-06512:at "SYS.DBMS_STATS", line 24281

ORA-06512:at "SYS.DBMS_STATS", line 24332

ORA-06512:at line 1

異常原因：查詢test表統(tǒng)計信息stattype_locked值，發(fā)現統(tǒng)計信息被鎖定

SQL> select owner,table_name,stattype_locked from dba_tab_statistics a where a.stattype_locked in ('ALL','DATA','CACHE') and table_name='TEST';

OWNER TABLE_NAME STATTYPE_L

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

SYS TEST ALL

處理方案：將統(tǒng)計信息解鎖，然后在執(zhí)行更新

SQL>exec dbms_stats.unlock_table_stats(ownname => 'SYS',tabname => 'TEST');

PL/SQLprocedure successfully completed.

SQL>exec dbms_stats.gather_table_stats('SYS','TEST');

PL/SQL procedure successfully completed.
注：stattype_locked為空代表統(tǒng)計信息未鎖定，為all表示表的統(tǒng)計信息被鎖
