The update logger can be enabled once the FILE-XREF file is built and the files to be excluded from update logging are selected. Use the :ULOG-ON command to enable the update logger. All tracked updates are logged and queued in special buffers created from the available disk space area; they remain in these buffers until the transaction logger dequeues them and writes them to backup medium. Each transaction is serialized and assigned a Global Transaction Number.
Transaction logging can be started at any time, including while transactions are being queued by the update logger. Use the :ULOG-OFF command to stop update logging at any time.
