MRP0: Detected read corruption! Retry recovery once log is re-fetched...


Solution:

Don't disturb recovery mode. If down, then bring the DB into recovery managed mode again. Register the archive log(s) which is/are not recovered.

SQL> alter database register logfile '/u03/ARCBKP/1_918_829075801.dbf';

Sure recover will be started.
Sure archive logs will start applying if cataloged already.
