今天开发库在线创建一个索引,创建了1个多小时,还没有完成。强制取消后,删除索引报错

重新创建索引,会告诉你该索引已经存在,drop index ,会告诉你该索引被锁,或者是 ORA-08104(this index object xxxxx is being online built or rebuilt) 错误。

该过程失败之前创建的一些临时对象由 SMON 负责清除,,糟糕的是, SMON 可能会不作为--我在 9i 上观察是 2 个小时(周期?)才清除掉。

在 10g 版本, Oracle 的 DBMS_REPARE 包新增了: online_index_clean ,能够手工进行清除:

dbms_repair.online_index_clean(
object_id    IN BINARY_INTEGER DEFAULT ALL_INDEX_ID,
wait_for_lock IN BINARY_INTEGER DEFAULT LOCK_WAIT)
RETURN BOOLEAN;

SQL> declare
  2    done boolean;
  3  begin
  4    done:=dbms_repair.online_index_clean(194884);
  5  end;
  6  /
PL/SQL procedure successfully completed.
 
Elapsed: 00:00:00.43
 
再次删掉索引,成功。
