根据Metalink方法进行解决。

Metalink Doc ID: 751787.1

Solution

Use the hidden parameter _max_io_size that can be used to set the size of the individual read buffers allocated by recovery.

So set this parameter to 4194304 (ie 4Mb) in the init.ora/spfile then that should be good enough to
function as a workaround and allow recovery.

_max_io_size=4194304

As a fix apply the one of available for your version of oracle ,if not check with Oracle support if a one off can be made available via a backport
