Extracting in Physical Key Sequence

With UPDATE=YES, the physical extract occurs with the rules as previously described (for Native Key sequence) without MULTUSE=YES.

Without UPDATE=YES, the physical extract executes with few requirements and no protection. It was designed for the special case of extracting the data with I/O errors or during maintenance for a hot backup. With no protection, the data is the best that it is possible to get by reading what is on the DASD at the time it is read. This option should be executed when the submitter is watching or controlling other activity.
