Abstract: A page query method and a data processing node in an OLTP cluster database are disclosed. The OLTP cluster database includes a central node and at least one data processing node, the central node manages a PLock in a passive PLock releasing processing manner, and the method includes: searching a shared memory for a page digest of a first page when the data processing node needs to query the first page during a data query and the first page is not in storage space of a database buffer; and if it is determined target data of the data query cannot be on the first page, skipping performing a query operation on it; or if it is determined the target data may be on the first page, loading it into the storage space of the database buffer, and traversing the first page to perform the data query.
