Errors with log /u04/InfoVista/oradata/IVDB/IVDB_DRY/archivelog/2012_05_30/log_1.arc
MRP0: Background Media Recovery terminated with error 12801

And as you guys can see, because of this error, my media recovery is shutdown automatically. I tried google it this issue but there is no definite answer, so hope anyone can give me some tips and maybe some steps i can follow to throw this error far far away. Thanks in advance. :)
