XPC backup for in-process audit |
摘要 |
Method and apparatus for providing backup memory storage for audit trail data within a computer system having a main memory storage, a non-volatile memory storage, and backup memory storage. The computer system executes a number of transaction programs which generate audit trail entries. As the audit trail entries are generated, a portion of the audit trail entries are stored in a portion of the main memory storage to create an audit trail. The audit trail entries are accumulated in the portion of the main memory storage until a request is received to write the portion of the main memory storage to a corresponding portion of the non-volatile memory. Subsequent portions of the audit trail entries are accumulated in subsequent portions of the main memory storage. An output transfer to the backup memory storage is made once a sufficient number of portions of the main memory storage have been written to corresponding portions of the non-volatile memory in order to maximize the transfer efficiency to the backup memory storage. |
