摘要:
A mechanism is provided for deciding whether to install a first application within one of a plurality of candidate environments. An environment comprising one or more other applications. The first application and a candidate environment are analyzed to determine whether there is the potential for the first application to interact in an unintended manner with an application in the candidate environment. If there is no such potential, then the environment is identified as a suitable environment into which to install the first application. An unintended interaction is when a rule would be broken by an interaction between the first application and an application in the candidate environment.
摘要:
A method, apparatus and computer program are disclosed for modifying an application comprising a plurality of modules. A user is presented with a list of modules. The user is able to specify input regarding any permitted version modifications for the modules listed. It is then determined whether the requested modifications are possible with one or more failure messages being output when any of the requested modifications are not possible. At least one of the failure messages is used to enable modification of the initial input provided by the user. In one embodiment, information is provided to the user based on one or more failure messages in order to enable the user to modify their choices. In another embodiment, the initial input is automatically modified. A permitted version modification may be, for example, a version upgrade, a version downgrade, and an indication that there is no preference.

摘要:
A technique for transaction recovery by one transaction manager of another transaction manager's transactions in which each transaction manager is adapted to manage two phase commit transactional operations on transactional resources and to record commit or rollback decisions in a transaction recovery log. The recovery transaction manager detects apparent unavailability of the another transaction manager for transaction processing and initiates a transaction recovery process for the another transaction manager's transactions. This process also determines whether any of the transactions of the another transaction manager have all respective resources prepared to commit without there yet being a pending commit decision record in the another transaction manager's recovery log. If so, the recovery transaction manager writes a rollback record indicating an intention to roll back the identified transaction, in the another transaction manager's recovery log provided no commit decision record has been recorded.

A satellite system for observing space objects includes two or more satellites positioned in an Earth orbit and configured to observe objects in various orbits including those viewed (i) against the Earth's background; (ii) against a sunlit Earth background; and (iii) against a space background. An electromagnetic sensor may be provided on at least one of the satellites that is responsive to electromagnetic radiation having a wavelength that discriminates against substantial reflection of electromagnetic radiation from the Earth's atmosphere to observe the space object. A method of observing a space object using a satellite system is also disclosed.
摘要:
A data processing method, apparatus, computer program product, and service for assuring timely execution of compensation for non-transactional work which is carried out in a transaction under which a data item is processed. A lock is taken before the data item is processed and, in the event the transaction fails, the same lock is also obtained before the data item is re-processed. As a result, re-processing of the data item is held until the lock obtained by the failed transaction is released and this is only done once compensation of non-transactional work is complete. Thus, compensation completes before the message is re-processed.
