The requestor can then make a compensating transaction that reverses the effect of a transaction that has already committed.

请求方随后可生成一个补偿事务，将先前已经提交的事务的作用抵消。

youdao

Because both of these operations are running in the same transaction and the previous access to EIS2 is read-only no compensating transactions are required at this stage.

因为这两项操作都是运行在同一事务中，而前面对EIS2的访问是只读的，所以在这一段中需要补偿事务。

youdao

For example, in the case of compensating transaction failure you could send notification to the system administrator, or use messaging technology to retry these transactions at a later time.

例如，在补偿事务失败的情况下，您可以向系统管理员发送通知，或者用消息技术稍后重试这些事务。
