Abstract: Techniques are provided for fallback authorization routing. A merchant processor may receive authorization requests from one or more merchant systems. These authorization requests may be to authorize a transaction. The merchant processor may transmit these authorization requests over a first communication channel to an acquirer processor, which may then forward the requests to a payment network. If the merchant processor determines that the acquirer processor is not receiving the authorization requests, or is otherwise unavailable, the merchant processor may, as a fallback, transmit the authorization requests directly to the payment network through a second communication channel, thereby bypassing the acquirer processor. When the merchant processor receives some indication that the acquirer processor is available to process authorization requests, new authorization requests can be transmitted to the acquirer processor via the first communication channel.

Abstract: A secondary pool of VMs is used to run secondary services or jobs, which may be evicted upon failure of a corresponding primary VM. Upon detection of a failure of a primary resource, the secondary services or jobs are evicted from secondary pool resources, and the secondary pool resources can be automatically allocated to the jobs of the failed primary resource. In this regard, a secondary job may be thought of as a preemptible job and comprises services or jobs that are lower priority than the service or job on the primary resource. By using computing resources in the secondary pool to run secondary or preemptible jobs, this technology makes use of what would be otherwise idle resources. This beneficially avoids having to allocate additional and separate computing resources for secondary jobs, leads to more efficient use of network resources, and reduces costs.

Abstract: A clustered pair of data storage nodes employs a time-to-live (TTL) mechanism by which a preferred node communicates permission for continued operation to a non-preferred node. During non-errored TTL operation, host I/O requests to a data storage object are serviced, with write-type requests being replicated to the other node.

The polarization process includes: (1) each node contacting a witness node to request survivor status, (2) the witness node granting survivor status to the first node requesting it and denying survivor status to a later-requesting node, (3) at the node granted survivor status, continuing to service the host I/O requests without replication, and (4) at the other node based on being denied survivor status, discontinuing servicing of the host I/O requests.

Abstract: A method and an apparatus for data management through timer compensation in a wireless communication system are provided. In the method, when a data loss occurs at a first point, whether a data loss has occurred previously and so whether a timer is being driven are determined. Whether the driven timer stops or expires at a second point is determined. When the timer stops or expires at the second point, a timer value is compensated for with consideration of a time difference between the first point and the second point. A timer for the data loss of the first point is restarted based on the compensated timer value. Therefore, a delay of a retransmission request time for lost data in an RLC (Radio Link Control) layer may be minimized.

Abstract: An approach to detecting processor failure in a multi-processor environment is disclosed. The approach may include having each CPU in the system responsible for monitoring another CPU in the system. A CPUn reads a timestampn+1 created by CPUn+1 which CPUn is monitoring from a shared memory location. The CPUn reads its own timestampn and compares the two timestamps to calculate a delta value. If the delta value is above a threshold, the CPUn determines that CPUn+1 has failed and initiates error handling for the CPUs in the system. One CPU may be designated a master CPU, and be responsible for beginning the error handling process. In such embodiments, the CPUn may initiate error handling by notifying the master CPU that CPUn+1 has failed. If CPUn+1 is the master CPU, the CPUn may take additional steps to initiate error handling, and may broadcast a non-critical interrupt to all CPUs, triggering error handling.

Abstract: Systems and methodologies are described that facilitate utilizing timers in conjunction with transmitting buffer status reports (BSR). A prohibit timer can be utilized to determine when BSRs can be transmitted to an eNB. The prohibit timer can be initialized or restarted upon transmitting a BSR to an eNB.

Control data feedback can additionally be used to determine when to retransmit the BSR. In addition, in either case, the timer duration values can be provided by the eNB.

Abstract: The present invention provides a computer implemented method and apparatus for unmounting file systems from a plurality of file servers. The method comprises of issuing an unmount command targeting a file system of a first server among the plurality of file servers. The timeout period is then expired without receiving an unmount acknowledgement associated with the unmount command. Thus, the timeout period is associated with an allowable time for the file system to acknowledge unmounting. In response to expiring the timeout period, a ping is transmitted to the first server among the plurality of file servers. The ping timeout then expires based on a failure to receive a ping acknowledgment corresponding to the ping. This action marks the first server for a later retry of unmounting to form a marked set based on the first server.

The central computer also scans a subset of ports of the local computer, to ascertain whether the problem is due to a temporary unavailability of the application.
