Abstract
A method, system, and program product for modifying a high performance multi-write database is provided. The method includes registering data pages configured for reading by a first node within a buffer pool structure of a database. Share lock functionality is enabled. The share lock functionality is disabled after the first node has completed reading the data pages and the data pages are registered with respect to a second node for writing functionality. A notification indicating that a group of data pages has expired is generated and transmitted to the second node. Exclusive lock functionality for allowing the second node to read and modify the data pages is enabled and after the modification the exclusive lock functionality is disabled. Reading functionality is enabled for the first and second nodes to read the group of data pages from a high performance cache structure of the buffer pool structure.
