Abstract: Disclosed are a method and device for timeout monitoring, comprising: determining key information of a request message, the key information including a sending time of the request message; storing the key information to a first level cache; scanning the first level cache according to a set frequency, if the first level cache includes a first request message, storing the key information of the first request message into a second level cache, the first request message being a request message for which a reply message is not received; scanning the second level cache, and determining by a message log whether a reply message is received for a second request message in the second level cache, if not, the second request message times out, the second request message is a request message in which the difference value between a sending time and a current time is greater than a time-out threshold.

Abstract: The present invention relates to a data processing system for providing business continuity protection, comprising: a business center comprising a first data processing unit, a first pre-communication unit, and at least a first post-communication unit; a disaster recovery center comprising a second data processing unit, a second pre-communication unit, and at least a second post-communication unit; wherein the first pre-communication unit and the second pre-communication unit are communicatively coupled to the first post-communication unit respectively when the business center operates normally; the first pre-communication unit and the second pre-communication unit are communicatively coupled to the second post-communication unit respectively when the disaster recovery center operates in place of the business center. The data processing system can reliably switch between the business center and the disaster recovery center, thereby providing a complete protection for the business continuity.
