The present invention discloses a method and a system for resending messages with a minimized number of retries and maximized timeliness of delivering the message to the receiving party. The method sets a retry period for a message that needs to be resent, determines a retry time according to the retry period, and sends the message after the retry time is reached. The retry period increases as the number of retries increases. The method and the system can ensure reliable delivery of notification messages and support many transmission protocols between different systems, does not require the receiving party to implement complicated interaction protocols to reliably receive a notification message, and is suitable for widespread use in the Internet. Moreover, the disclosure supports multiple transaction processing, can be used as a common business transaction application platform, and allows flexible expansion of multiple transactions and multiple protocols.

A failure analysis system (900) for printed circuit board (600) includes testing equipment (100) and a monitor (200). The testing equipment includes a base (120), a fixing body (180), a supporting arm (140) and a micrometer (160). The fixing body and the supporting arm are both firmly fixed on the base. The printed circuit board is fastened to the fixing body. The micrometer is slidingly attached to the supporting arm. The micrometer has a pin (1612) at one end thereof for resisting one end of the printed circuit board. The monitor electronically connects with the printed board for receiving signals from the printed circuit board. When the pin of the micrometer reaches a certain position, the signal transmitted to the monitor is broken.

A method of automatically adjusting a size of a copy-on-write (COW) disk space of a snapshot device is provided. A first disk space of a snapshot device is initialized, and a COW operation is performed on a chunk of the first disk space. Next, it is determined whether a chunk sequence number of a write request is in the first disk space. Then, if the chuck sequence number of the write request is in the first disk space, the first disk space is maintained. Then, if the chuck sequence number of the write request is not in the first disk space, a second disk space is initialized, and the number of chunks of the second disk space is the same as the number of maximum successive chunks of the first disk space, and then, the COW operation is performed on the chunk of the second disk space.
