    摘要: A server apparatus is operable in communication with mobile client apparatuses for securely recording the occurrence of a transactional exchange meeting between holders of the mobile client apparatuses. A token component sets up a meeting arrangement mediated by the server and to communicate a first issued token to a first mobile client apparatus and a second issued token to a second mobile client apparatus. A token validator component receives at least a portion of each of the tokens from the mobile client apparatuses. The token validator component validates that the at least a portion of the token received from the first mobile client apparatus matches at least a portion of the second issued token, and vice-versa. A transaction recorder component creates and maintains a secure record of at least the request, the response, the validation of the tokens, and a completion signal from each of the mobile client apparatuses.

    摘要: A method for maintaining data access during failure of a controller in a multiple controller storage subsystem (103) is provided. The storage subsystem (103) has an array of data storage devices (109) and more than one controller (104, 105) for managing the data storage. The method comprises a first controller (201) saving its internal state information (212) and, optionally, resetting itself (213). One or more of the other controllers (202, 203) carry out the steps of pausing operation of the controller (221, 231), saving internal state information of the controller at the time of pausing (222, 232), and continuing operation of the controller (223, 233). The one or more other controllers (202, 203) may pause operation and save their internal state information when they receive a message broadcast (220, 230) from the first controller (201) which has detected an error.
