文档解释

ORA-24058: cannot downgrade QUEUE_TABLE that has propagation in a prepared state

Cause: An attempt was made to downgrade the queue table when there were messages being propagated that were in the prepared state.

Action: Wait for the propagation to complete before retrying the operation.

ORA-24058错误是Oracle给出的一个异常码，表明队列表含有已准备好传播的队列，或者在队列表上已设置监听。当开发者试图通过ALTER QUEUE TABLE语句对队列表进行降级时，系统会报告此种错误。

官方解释

常见案例

一般处理方法及步骤

1.使用DBMS_AQADM.STOP_QUEUE（）停止队列表上的传播或监听。

2.使用AQADM.DROP_QUEUE（）为队列表中的所有队列删除传播或监听。

3.使用ALTER QUEUE TABLE语句降级队列表的版本。

4.使用AQADM.START_QUEUE（）重新启动已停止的传播或监听。
