rman is not deleting old archive logs when used in data guard env

Hi,

 rman is not deleting old archive logs when used in data guard env.
 In Aug, 2011, I opened SR 3-3939472271 with oracle regarding the same issue. I was instructed to:
        1- alter system set "_log_deletion_policy"='ALL' scope=spfile; and bounce oracle.
        2- Also, I was instructed to add
 CONFIGURE ARCHIVELOG DELETION POLICY TO APPLIED ON STANDBY;

        Did not have time to test the above instruction from Oracle in data guard env in oracle 10.2.0.4. Now, I found it does
        not work.

        Today, I just opened 3-4601556401. Did anybody have the same issue?
Here my configration

Recovery Manager10.2.0.4.0
ORACLE_HOME = /u00/app/oracle/product/10.2.0/Db_1
