Delete old archive logs

I need a script to delete archive logs that are more than 7 days. I will like this script to run once a week. I am running Oracle 8.1.7 on Windows 2k and 7.3.4 on NT4.0. Any assistance will be appreciated.
Thanks

Hey, i did a script that do this, but delete older than 30 days, just modify my script.


Here's a way to delete your archive logs files automaticaly.
This script delete archive logs that have more than 30 days.
It is very useful when you need the disk space.
Of course, make sure that you have valid backups,
cuse you could delete archive that you need.


First, i give grant to objects owned by the user sys.
Then, i create a directory to use the bfilename function.
After, i create a procedure that extract the name of the archive
and one that finds old archive logs and delete them.


You can execute that procedure manualy, or create a job that will execute
that procedure periodicaly.

---------------------------------------------------------------------------------------
connect sys/YOUR_SYS_PASSWORD


grant select on v_$archived_log to YOUR_USER;
grant execute on dbms_backup_restore to YOUR_USER;


connect YOUR_USER/USER_PASSWORD

create or replace directory ARCHIVEDIR as 'd:\ora8i\orant\oradata\archive';

create or replace function proc_nom_fich(P_chain IN Varchar2) return varchar2 IS
l_posi number;
l_nom_fich varchar2(100);

begin
l_posi := length(P_chain);
loop
if substr(P_chain,l_posi,1) in ('/','\') then
l_nom_fich := substr(P_chain,l_posi + 1);
exit;
else
l_posi := l_posi - 1;
if l_posi < 0 then
exit;
end if;
end if;
end loop;

return(l_nom_fich);
end;
/

create or replace procedure proc_dele_arch_log is
arch_file bfile;
arch_exis boolean;
arch_file_name varchar2(100);

cursor sel_archive is
select name
from v$archived_log
where completion_time < sysdate - 30;

begin
for list in sel_archive loop
arch_exis := FALSE;
arch_file_name := proc_nom_fich(list.name);
arch_file := bfilename('ARCHIVEDIR',arch_file_name);
arch_exis := dbms_lob.fileexists(arch_file) = 1;

if arch_exis then
sys.dbms_backup_restore.deleteFile(list.name);
end if;
end loop;
end;
/

I wrote a winbatch that does this for me. There is also an Oracle package called DBMS_BACKUP_RESTORE which has some functions for purging archive files. But the functions do not work. They will however clear out the sys.v_$archived_log table quite well. Winbatch is a windows scripting tool that you can buy from http://www.winbatch.com. I have had good success using it.

DBMS_BACKUP_RESTORE.DELETEFILE work fine!

Then, schedule DELARCH.CMD with AT command of NT.

Pl. comment.

Thanks,

Thanks all of you for replying. I really appreciate the help. I have one more question.
Sam, I tried your script and it is doing what I want, but I have some really old archive logs that do not fall into the 7 day range and I will like those deleted first before I start scheduling the script to run weekly. Sould you help me fix it so that they also get deleted.

Hi,

Either delete 'em manually first or change the date range in my query.

Also pl. note that in my query, I have hard coded 'FRIDAY' as we take cold backup on Friday night.

Thanks,

Thanks Sam. I tried that and it worked.
