How to delete the standby archive log files in ASM?

Question

Hi Experts
we have a realtime downstream replication that is using the a location in ASM to put the shipped logs files.
set up by
ALTER SYSTEM SET LOG_ARCHIVE_DEST_2='LOCATION=+BOBOASM/NANPUT/standbyarchs/
VALID_FOR=(STANDBY_LOGFILE,PRIMARY_ROLE)' Scope=BOTH;
What shall i do to clean up those files ?
Any procedure or script to do that?
Thanks

Hello Haggylein
check this out, seems to work
--- redologs used or not?
---- when purgeable we can delete it
COLUMN CONSUMER_NAME HEADING 'Capture|Process|Name' FORMAT A15
COLUMN NAME HEADING 'Archived Redo Log|File Name' FORMAT A25
COLUMN FIRST_SCN HEADING 'First SCN' FORMAT 99999999999
COLUMN NEXT_SCN HEADING 'Next SCN' FORMAT 99999999999
COLUMN PURGEABLE HEADING 'Purgeable?' FORMAT A10
SELECT r.CONSUMER_NAME,
r.NAME,
r.FIRST_SCN,
r.NEXT_SCN,
r.PURGEABLE
FROM DBA_REGISTERED_ARCHIVED_LOG r, DBA_CAPTURE c
WHERE r.CONSUMER_NAME = c.CAPTURE_NAME and PURGEABLE = 'YES';
-- Now the script
-- to be executed on the downstream database
-- generate the list of logs to be purged and executed in a ksh script
-- sqlplus "/as sysdba" @$HOME/bin/generate_list.sql
SET NEWPAGE 0

SET TERMOUT OFF

SET HEADING OFF
SET MARKUP HTML OFF SPOOL OFF
spool list_purgeable_arch_redologs.ksh
SELECT 'asmcmd ls ' || r.NAME
FROM DBA_REGISTERED_ARCHIVED_LOG r, DBA_CAPTURE c
WHERE r.CONSUMER_NAME = c.CAPTURE_NAME and PURGEABLE = 'YES';
spool off
exit
# eventually we can call it from a script
# !ksh
# delete of the shipped redologs
# to be performed on node 2
# not to be used on

./list_purgeable_arch_redologs.ksh
exit
