RMAN-06562: available space of number kb needed to avoid reading the backup set multiple times

RMAN-06562: available space of number kb needed to avoid reading the backup set multiple times
Cause: A backup set is read more than once. Multiple reads of a backup set can slow restore performance. One of the following could have caused this: 1) The MAXSIZE option is used but is not large enough to restore files. 2) Files should be restored to a recovery area, but the available disk space is not large enough to restore files.
Action: One of the following: 1) Increase the MAXSIZE parameter and retry the command. 2) Free up disk space in the recovery area.
