文档解释
ORA-25241: cannot change correlation ID from string to string without FIRST_MESSAGE option
Cause: An attempt was made to change the correlation ID while using the NEXT_MESSAGE or NEXT_TRANSACTION option for dequeuing.
Action: To use a correlation ID that is different from the previous dequeue call, reset the dequeuing position by using the FIRST_MESSAGE navigation option.
【详细说明】
ORA-25241 是Oracle在操作MQ_MESSAGE_PROPERTIES_T时发出的一个错误。它表明在更改相应的消息服务器的相关性标识(correlation ID)时,没有提供FIRST_MESSAGE参数,从而引发了错误。
【官方解释】
ORA-25241: cannot change correlation ID from string to string without FIRST_MESSAGE option
cause: The message propagation in database could not change the correlation id from one
value to another because the FIRST_MESSAGE option was not included.
action: Change the message header for the message id and include the FIRST_MESSAGE option when
changing the correlation id
常见案例
当消息被发送到消息服务器时,一个字符串类型的相关性ID(correlation ID)将会被赋予给它,用于标记消息,以便接收者与该消息关联。当消息被接收之后,经常需要更改这个相关性ID,但更改之前要确保原来的ID已经被确认。如果用户没有在更改相关性ID时提供FIRST_MESSAGE参数,ORA-25241错误就会发生。
【正常处理方法及步骤】
要解决ORA-25241错误,可以按照以下步骤进行:
1. 确保在更改相关性ID之前,消息的原始ID已经被确认。
2. 更改消息头中的消息ID,并在更改相关性ID时加入FIRST_MESSAGE参数。
3. 重新提交消息,查看更改是否已经生效。
