Using Online Backup

You can create a copy of the current state of a database without shutting down any of the database’s processes by invoking nuocmd hotcopy.

For more information on nuocmd and other command line tools, see Command Line Tools.

Hot copy is a mechanism for copying a database’s archive and journal from one of the database’s running Storage Managers (SMs) The advantage of a hot copy is that it is an online procedure. Your database remains running and available during the hot copy operation.

The target hot copy directory should not be removed or renamed during a hot copy operation. If that occurs, the SM will exit with the following error message: Unable to create archive directory: No such file or directory.
