RMAN backup in RAC failing with error ORA-19566

Question

Hi all, i have 2 node RAC and i am trying to take rman backup of the database which is in ASM filesystem.
There is a corruption in SYSAUX file and rman is failing to take backup of the sysaux datafile and error thrown at the end like
piece handle=/home/oracle/orabackup/BLOOM_LVL0_20120627_1qnejueh_s58_p1 tag=TAG20120627T185538 comment=NONE
channel ORA_DISK_1: backup set complete, elapsed time: 00:00:56
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03009: failure of backup command on ORA_DISK_1 channel at 06/27/2012 18:56:17
*ORA-19566: exceeded limit of 0 corrupt blocks for file +DATA/bloom/datafile/sysaux.257.775475317*
Then i tried to validate the backup in rman of the datafile sysaux nad fired the following query
SQL> SELECT * FROM v$database_block_corruption;
FILE# BLOCK# BLOCKS CORRUPTION_CHANGE# CORRUPTIO
3 32011 1 0 ALL ZERO
3 32049 40 0 ALL ZERO
3 32034 1 0 ALL ZERO
3 28964 1 1399837 LOGICAL
3 32015 2 0 ALL ZERO
and found all the blocks in the table WRH$_SQL_PLAN.
Then dropped the table, and tried to take backup of the database and it is failing again with the same error..
ANY SOLUTION TO TAKE BACKUP OF THE DATABASE.
anyhow we can SET MAXCORRUPT FOR DATAFILE 3 to value, but does this works all time...
Thanks in advance,
TEJAS

Both are good suggestions, but

Or Skip Option
Like

3> BACKUP DATABASE;
4> }The OP was aware of this option and hopefully was able to get at least some sort of a backup eventually. But as for the dropped WRH$_SQL_PLAN, TEJAS is, I will use the word "braver" than most. And as often is the case, Dan Morgan offered the only bit of sensible advise.
Open an SR.
Good luck.
