摘要: A framework for in-memory space management for content management database systems is provided. A per-instance in-memory dispenser is partitioned. An incoming transaction takes a latch on a partition and obtains sufficient block usage to perform and complete the transaction. Generating redo information is decoupled from transaction level processing and, instead, is performed when block requests are loaded into the in-memory dispenser or synced therefrom to a per-instance on-disk structure.

摘要: A system, method, computer program and article of manufacture for updating a disk that moves updates for a specific database object into available contiguous free data blocks, and writes the multiple updates to disk using a single disk access, maintaining database transactional and durability semantics.
