Method, memory system, and computer program product for implementing lock based delayed space recycle control

摘要

A method, memory system, and computer program product are provided for implementing lock based delayed space recycle control. The memory space recycle method is used with a memory in a computer system. A data element lock is obtained for a data record in a data block. Then an update on the data record is performed. A waiting to be recycled index for the data block is maintained. The waiting to be recycled index includes a record number, an address of the large object block (LOB) and the length of the LOB space. When the last lock on a data element is about to be released the waiting to be recycled areas associated with that data element are freed.
