摘要： A mechanism for negotiating a relatively transport agnostic communication protocol for use in accomplishing a distributed activity. The potential protocols subject to negotiation may be, for example, extensions to Web Services Coordination. In that case, when the initiator creates a transaction, the initiator also negotiates the desired protocol with its transaction manager. The transaction manager and any other participants in the transaction will then follow that negotiated protocol when communicating with the transaction manager. The protocol may be selected to improve performance and may be tailored to existing needs and capabilities.

摘要： Mechanisms for securely allowing a participant computing entity to engage in a transaction initiated by an initiator computing entity and managed by a coordinator computing entity. The initiator provides a transaction initiation request to the coordinator. Upon receipt, the coordinator accessing a transaction coordination context that includes information such as a secure key that may be used by a participant to register in the transaction. The coordinator then provides the coordination context to the initiator, which provides the coordination context to the participant(s) that are also to engage in the transaction. Each participant then generates a registration request that is based on the coordination context, and that is secured using the secure key provided in the coordination context.

摘要： Minimizing transaction managers. A method that may be practiced in a commit tree topology including a plurality of transaction managers to manage transactions. The transactions include a set of operations that are all performed if a transaction is completed or all aborted if a transaction is not completed. The transaction managers store transaction result information to allow recovery of a transaction in case of system failure. The method includes acts for minimizing storage overhead by minimizing the number of transaction managers used to coordinate transactions. The method includes identifying a set of transaction managers. A first transaction manager is selected from among the set of transaction managers. A second transaction manager is identified from among the set of transaction managers that is always available when the first transaction manager is available. Messages are redirected from a subordinate associated with the first transaction manager to the second transaction manager.

摘要： The present invention extends to methods, systems, and computer program products for controlling transactions in accordance with role based security. A first transaction related component receives a transaction related message from a second transaction related component. The transaction related message indicates a request by the second transaction related component to perform a transaction related operation that is to involve the first transaction related component. The first transaction related component authenticates the second transaction related component. The first transaction related component refers to transaction control information indicating roles the second transaction component is permitted to assume relative to the first transaction related component. The transaction related operation indicated in the request is compared to the permitted roles for the second transaction related component. The transaction related operation is implemented in accordance with the results of the comparison.

摘要： A transaction manager virtualization layer is provided for supporting multiple active transaction managers in a cluster or node. By virtualizing the transaction managers, applications and services are enabled to migrate across cluster nodes or even outside a cluster that includes relevant recovery mechanisms for transactions that are not completed at the time of migration. Multiple implementations of a transaction manager may be enabled to run side-by-side in a node or cluster allowing a rolling upgrade of transaction managers in clusters.

摘要： A transaction protocol is described that allows a database transaction to begin as a local, lightweight transaction without involving a distributed transaction coordinator and then be promoted to a distributed transaction only when required, e.g. when more than one database connection is required. A promotable enlistment allows a first resource to begin processing a promotable transaction. If the resource is notified that the transaction is being promoted to a distributed transaction, the resource is configured to promote the enlistment to a distributed transaction coordinator which coordinates processing of the transaction between the first resource and at least a second resource.

摘要： The present invention extends to methods, systems, data structures, and computer program products for maintaining correct transaction results when transaction management configurations change. An intermediate transaction manager is transparently interposed between one or more resource managers and a plurality of transaction managers. The intermediate transaction manager multiplexes and intercepts calls and notifications between the one or more resource managers and the plurality of transaction managers. The intermediate transaction manager is configured to wrap recovery cookies with transaction manager type information and identity information that identify transaction managers. The information can be used to re-attach to the transaction manager to recover the correct outcome of the transaction. The intermediate transaction manager can also intercept recovery-complete calls directed to a specific transaction manager and send the recovery-complete call to each of the plurality of transaction managers. Resource managers can receive, store, and send wrapped recovery cookies.

摘要： A manifold device is provided for use with a valve assembly, an aspiration source and a dispensing source to transfer fluid from at least one of a plurality of fluid reservoirs to at least one test site on a substrate surface. The manifold device includes a manifold body that defines a plurality of fluid aspiration conduits, for fluid aspiration in an aspiration position, and a plurality of fluid dispensing conduits to selectively dispense at least one droplet of the corresponding liquid sample slug, in a dispensing position. In the aspiration position, the respective sample paths are out of fluid communication with the dispensing source and, in the dispensing position, the respective sample paths are out of fluid communication with the aspiration source.

摘要： A universal calibration apparatus and method to estimate the dispense output from a low volume, non-contact, liquid dispensing systems that may be applied for every hardware configuration (e.g., tube length, orifice diameter, tip design, etc), reagent solution property and environmental condition. This same calibration technique is applied to calibrate or tune these non-contact liquid dispensing systems to dispense desired volumes (in the range of about 0.050 μL to 50 μL), irrespective of the hardware configuration or the solution properties. That is, the calibration technique is not dependent on any variables, but the result (the actual dispense volume) is dependant on the variable mentioned. By actuating selected pulse widths, and measuring the resulting volume, a Calibration Profile can be generated correlating the liquid volume dispensed from the orifice to the respective pulse width of the dispensing valve thereof through calibration points. In particular, one is selected to deliver a first volume of liquid that is less than a lower base pulse width correlating to the lowest volume of the selected range of volumes of liquid, while a second pulse width is selected to deliver a second volume of liquid dispensed that is greater than an upper ceiling pulse width correlating to the highest volume of the selected range of volumes of liquid. Intermediary pulse widths are also applied, each selected to deliver a different, spaced-apart, respective intermediary low volumes of liquid dispensed from the dispensing orifice between the first volume and the second volume. Thus, applying the Calibration Profile, the pulse widths correlating to the one or more targeted discrete volumes for liquid dispensing can be extrapolated.
