ORA-14403 错误是在获取 DML 分区锁的时候检测到的光标无效的错误。

官方解释

ORA-14403: 被检测到的光标无效。当由于部分更改将空洞生成或空洞被垃圾收集时,可能发生这种情况。

常见案例

当尝试获取 DML 分区锁时可能会发生 ORA-14403。主要原因是向分区中插入记录或从分区中删除记录时可能生成空洞,从而导致光标失效。

正常处理方法及步骤

检查 SQL 语句,确保正确的参数被传递,以及是否有删除或插入记录,这可能会导致光标失效。

可以在 SQL 语句的序列中重新收集统计信息,来防止该错误的发生,如:

exec dbms_stats.gather_table_stats(ownname => ”, tabname => ‘

‘);

还可以重新构建(然后重做)字段索引以防止光标失效:

ALTER INDEX REBUILD;
