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

ERRORavailable space of number kb needed to avoid reading the backup set multiple times
CAUSEA 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.
ACTIONOne of the following: 1) Increase the MAXSIZE parameter and retry the command. 2) Free up disk space in the recovery area.
