In a stacked system, errors detected at a user application interface of one or more host systems are associated with root cause errors at a stack level below a virtualization layer by detecting an error at a user application interface; identifying an associated root cause error at a lower stack level; creating an error trace entry for the error; associating an error log identifier with the error trace entry; making the combined error log identifier and the error trace entry into an error identifier that is unique within the plurality of host systems in said stacked system; and communicating the error identifier to any requester of a service at a user application interface of one or more host systems when the service must be failed because of the root cause error.

The invention provides a fault diagnosis and pre-warning system in the oil refining production process and an establishment method of the fault diagnosis and pre-warning system. The method comprises the steps of establishing a multilevel flow model in the oil refining production process, determining a fault propagation path, conducting hazard and operability (HAZOP) analysis on the oil refining production process, determining a plurality of static nodes and a plurality of dynamic nodes, determining the connected relation of the static nodes and the dynamic nodes, establishing at least one alternative model, adopting the dynamic Bayesian network structure scoring mechanism for scoring of the alternative models, determining the alternative model with the highest score as a fault multilevel related model, determining the conditional probability relation between the static nodes and the dynamic nodes in the fault multilevel related model, and establishing a fault diagnosis and pre-warning module. The established fault multilevel related model and the fault diagnosis and pre-warning module have the higher fault propagation and fault tracing and reasoning capability, and accurate diagnosis and timely warning of faults generated in the oil refining production process can be achieved.

The invention discloses a method for determining path faults, a controller, a switch and a system. The controller instructs the switch to report the path where it is located after receiving a fault tracking message by presetting the flow entries of each switch included in the path to be detected. path label, the controller compares the received switch information corresponding to the path label with the predetermined switch information contained in the path to be detected corresponding to the path label, and determines whether the path to be detected is faulty according to the comparison result , where the controller only needs to send a fault tracking message to the initial switch on the path to be detected to complete the detection of at least one path, which improves the efficiency of path detection; and the switch only needs to be controlled by the controller during the whole process The functions of the data layer such as message forwarding and information reporting are completed, which is in line with the separation of the control plane and the forwarding plane in SDN.

The present invention provides a method and device for identifying low-order faults in deep tight sandstone gas reservoirs. The method includes: performing frequency division processing on post-stack seismic data of low-order faults to be identified, and obtaining seismic data in dominant frequency bands that can highlight low-order faults ; Perform directional filter processing on the dominant frequency band seismic data to obtain seismic data in four main directions; use the ant colony algorithm to calculate and obtain the tracking attribute body of each main direction according to the seismic data in the main direction; extract the faults of the faults in each main direction Traces, combined with tracking attribute volumes in each direction to obtain system diagrams, through frequency division and filtering of relatively poor quality post-stack seismic data, and recalculation using ant colony algorithm on the basis of the original ant volumes, Extract accurate fault traces and combine them with tracking attribute volumes in each direction to obtain system diagrams, which are applicable to seismic data of various mechanical properties and frequencies, and effectively improve the reliability of identification of low-order sequence faults.

The invention relates to a method for predicting the thickness of a compressive fault zone in the coverage area, comprising the following steps: selecting the stress environment of the work area as a compressive environment; interpreting the seismic data at the location of the compressive environment fault zone, identifying the fault, and obtaining the vertical Formation fault distance L; the thickness of the fault zone is calculated according to the formula H=kLd, where k and d are specific coefficients. The method for predicting the thickness of the compressive fault zone in the coverage area of ​​the present invention can identify faults and describe the fault distance through the fine interpretation of seismic data in the undrilled area or the area where no well drilled and encountered faults, and then use the thickness calculation formula to predict the fault zone Thickness, the present invention compares with the prior art (the thickness of the structural unit of the fault zone after the fault zone structure division of the well logging data is used to drill wells in the fault zone), the error produced by the two is less than 10%, and the prediction result is very accurate, therefore, The invention has great significance for developing faults to control reservoirs and selecting favorable oil and gas targets.
