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; the server 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: Provided is an efficient method for producing nickel powder from a solution containing a nickel ammine complex, the method including adding seed crystals to a solution containing a nickel ammine complex and subjecting the resulting mixture to hydrogen reduction under high temperatures and high pressures to produce nickel powder, which makes it possible to maintain the quality of the nickel powder produced and reduce the amount of the seed crystals used. The method for producing nickel powder is characterized by adding seed crystals and a dispersant having an anionic functional group to the solution containing a nickel ammine complex to form a mixture slurry, and subjecting the mixture slurry to pressurized hydrogen reduction treatment by blowing hydrogen into the mixture slurry in a high temperature and high pressure atmosphere to cause a reduction reaction, thereby reducing the nickel ammine complex in the mixture slurry to obtain nickel powder.

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.
