Finding Missing Archived Log For Streams

i'm trying to write a pl/sql to find all missing archived logs that are need for streams replication.

There is already a oracle metalink note for this. But yet it would give only the archive log name that contains my dba_capture.start_scn and we need to check if the files exist in disk or not!

The problem here is, when using ASM, dba_registered_archived_log view is truncation the file name and it is really difficult to pin point the logs. So is it fine to join this view with V$archived_log? is deleted and status column would do the trick? I modified the plsql as below. Is this fine/accurate?

CODEdbms_output.put_line('Capture will restart from SCN ' || lScn ||' in the following file:');
for cr in
(select decode (a.name, NULL, 'NOT FOUND', a.name) name, to_char(a.completion_time, 'hh42:mi:ss') completion_time from v$archived_log a,dba_registered_archived_log b where lscn between b.first_scn and b.next_scn
and a.deleted = 'YES' and a.status != 'A')
loop
f_rec :=1;
[code]......
