Abstract:
In a method for managing memory pages, responsive to determining that a server is experiencing memory pressure, one or more processors identifying a first memory page in a listing of memory pages in the server. The method further includes determining whether the first memory page corresponds to a logical partition (LPAR) of the server that is scheduled to undergo an operation to migrate data stored on memory pages of the LPAR to another server. The method further includes, responsive to determining that the first memory page does correspond to a LPAR of the server that is scheduled to undergo an operation to migrate data, determining whether to evict the first memory page based on a memory page state associated with the first memory page. The method further includes, responsive to determining to evict the first memory page, evicting data stored in the first memory page to a paging space.
