Distributed transaction processing method on basis of shared storage pool

The invention relates to a distributed transaction processing method on the basis of a shared storage pool. The distributed transaction processing method includes mapping all directory paths of a distributed file system to metadata servers on the basis of Hash; assigning a coordinator and a plurality of participators in a metadata server set with requirements on participating in distributed transaction; enabling the metadata servers to assess distributed transaction operation which need to be completed by the metadata servers, reporting 'termination' to the coordinator if the metadata servers cannot complete the distributed transaction operation, and reporting 'commitment' to the coordinator and locking resources if the metadata servers can complete the distributed transaction operation; enabling the coordinator to write the 'commitment' or the 'termination' into a global log of the shared storage pool according to report results of the participators and informing the participators; enabling the participators to execute the distributed transaction operation or cancel the locked resources; enabling the certain participator or the coordinator, which first checks a state of the distributed transaction, in the shared storage pool to set the distributed transaction into a 'termination' state when the coordinator or the participators fails. The distributed transaction processing method has the advantage that the transaction of metadata service in the distributed file system can be processed quickly in an extensible environment.

Broadband frequency response measuring method and broadband frequency response measuring device

ActiveCN111835434AAvoid wasting timeOvercoming the Limitations of Frequency SweepingTransmitters monitoringReceivers monitoringBroadbandingRadio frequency
The invention relates to a broadband frequency response measuring method and a broadband frequency response measuring device. The measuring method comprises the steps of carrying out second processingon an output signal generated by a radio frequency channel of a receiver in response to a transmitting signal to obtain a receiving sequence, and the transmitting signal being generated by a radio frequency channel of a transmitter in response to a signal obtained by carrying out first processing on a ZC sequence; and calculating to obtain a frequency response measurement result of the radio frequency channel to be measured according to the ZC sequence and the receiving sequence. The ZC sequence is applied to the broadband frequency response measurement process of the transmitter or the receiver; the limitation that frequency sweeping is carried out by utilizing a single-tone signal in the past is overcome; a new measurement scheme is provided, the amplitude-frequency characteristics in the frequency response of the to-be-measured radio frequency channel can be obtained, the phase-frequency characteristics in the frequency response of the to-be-measured radio frequency channel can also be obtained, and correction and compensation of the to-be-measured channel according to the obtained amplitude-frequency characteristics and phase-frequency characteristics in the later period are facilitated.
