If you need to restore (rollforward) the database, you can use this function to restore the archived log files.
You begin by selecting the range of log files to be restored.
All the log files from the first to the last log file selected will be restored.
"Synchronous execution" means that restoring takes place immediately and that the Control Center waits for it to complete. "Asynchronous execution" means that the restore process is passed to the server and that the Control Center does not wait for it to complete. In the latter case, you can start using the Control Center again immediately.
Under Storage locations, the names of the tapes on which the log files are stored may be displayed. This allows you to make sure you have all the necessary tapes ready before starting the restore.
