This application provides a distributed node phase synchronization method, electronic device, computer-readable storage medium, and program product. The method includes: receiving the output current of a node, a first square wave signal, and a second square wave signal, wherein the phase of the first square wave signal is the same as the phase of the output voltage of a first node, and the phase of the second square wave signal differs from the phase of the output voltage by a preset angle; obtaining the actual power angle of the first node based on the output current, the first square wave signal, and the second square wave signal; calculating the difference between the actual power angle and the target power angle; and adjusting the phase of the output voltage based on the difference when the difference is greater than a preset threshold, until the difference is less than or equal to the preset threshold. This solution can achieve synchronization of voltages at all transmitting and receiving ends, overcoming the limitations of traditional single-path control.

This application discloses a method for controlling the global list of running transactions in a database. This method maintains a global list of running transactions (GIL) in the memory of each database node, including a global short transaction list (G_STL) and a global long transaction list (G_LTL). When a local transaction ends, each node updates its GIL and broadcasts the state change to other nodes in the cluster via a transaction end broadcast (BOC), achieving decentralized global transaction state management. G_STL uses an ordered circular array structure, achieving fast location through transaction number differences; when a space out-of-bounds error occurs, it interacts with G_LTL to migrate and manage long transactions. This invention solves the problem that the traditional ProcArray structure is unsuitable for multi-node shared storage architectures, eliminates the network bottleneck of the central node, supports the efficient operation of high-concurrency transactions, and can complete transaction write-write conflict detection with extremely low latency.
