ORA-26841 是 Oracle AQ 队列管理器的错误代码,它表示没有找到请求的订阅者。

官方解释

ORA-26841: 没有找到认购队列”[schema.queue]”的订阅者。

常见案例

当你试图在一个队列上添加一个订阅者时,但没有成功时,你就可以得到这个错误代码:

BEGIN

DBMS_AQADM.ADD_SUBSCRIBER( queue_name => ‘my_queue’, subscriber => ‘my_subscriber’ );

END;

正常处理步骤

1、首先,列出所有订阅者:

SELECT SUBSCRIBER_NAME FROM USER_AQ_SUBSCRIBERS

2、检查你需要添加的订阅者是否已经存在于队列中:

SELECT * FROM USER_AQ_SUBSCRIBERS

WHERE QUEUE_NAME =’my_queue’

AND SUBSCRIBER_NAME=’my_subscriber’

3、如果没有,则添加订阅者:

BEGIN

DBMS_AQADM.ADD_SUBSCRIBER( queue_name => ‘my_queue’, subscriber => ‘my_subscriber’ );

END;

4、最后,检查订阅者是否已成功添加:

SELECT * FROM USER_AQ_SUBSCRIBERS

WHERE QUEUE_NAME = ‘my_queue’

AND SUBSCRIBER_NAME = ‘my_subscriber’
