The AA, or Archive Agent, also runs on the recovery server. It is used to extend Assure MIMIX for AIX’s rollback capabilities by recording redo and undo logs to media. The AA currently works with Tivoli Storage Manager (TSM). The AA uses the TSM API to send archive requests to TSM. When the logs are archived, they are always spooled in pairs. Depending on the TSM configuration the data is stored on media. A redo and an undo log are always together when the AA stores on media. This gives Assure MIMIX for AIX the ability to restore the data to any point in time. By unwinding the data with a course grained undo log, then applying fine grained redo log information to the log, the state of the data can be restored to any point in time.
