use rman`s DELETE OBSOLETE command

 

by: jl66Posted on 2009-08-03 at 08:47:36ID: 25005454

Thanks for info. If I want to remove any archive log old than 3 days. How to do it?

 

by: jl66Posted on 2009-08-03 at 08:55:20ID: 25005548

Background: have RMAN backups but the RMAN has no catalog repository.

 

by: mrjoltcolaPosted on 2009-08-03 at 11:42:15ID: 25007181

fluglash is correct, use RMAN to maintain archive logs on ASM. There really is no other option unless you move your archive destinations to regular disks, then you can use OS commands.

Make sure you have configured a retention policy. The RMAN delete archivelog command will use that to decide what it deletes and what it preserves.

To see or set a retention policy use:

rman target /
RMAN> show all;
CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 30 DAYS;

etc.


-- To delete the archive logs that are not required for that recovery window..
RMAN> delete archivelog all;


-- However, I prefer to be very careful and paranoid with archivelogs, so I want to have multiple backups
-- So prior to deleting, make sure to backup
RMAN> backup archivelog all;
RMAN> delete archivelog all;

Or a shortcut that will delete each log as it is backed up:
RMAN> backup archivelog all delete all input;


11g has an new archivelog retention policy that you can set, but you are running 10g so that is not an option.

To ensure multiple backups, I usually do:

RMAN> delete archivelog all backed up 3 times to sbt;

-- or

RMAN> delete archivelog all backed up 3 times to disk;

 

by: fluglashPosted on 2009-08-04 at 23:16:07ID: 25020536

to remove any archive log older than 3 days issue following comand:

RMAN> delete copy of archivelog all completed before 'SYSDATE-3';

 

by: jl66Posted on 2009-08-06 at 19:49:05ID: 25039714

Thanks for both updates. Can the above command be issued remotely?For example, I login server A and RMAN target sys/xxx@db1. db1 is located in server B. I issued this command in server A remotely. I was kicked out. So can I do that? Anything wrong with me?

 

by: mrjoltcolaPosted on 2009-08-06 at 19:55:24ID: 25039735

Yes, you can do it remotely. How were you kicked out? Can you give the RMAN or ORA error?

 

by: jl66Posted on 2009-08-07 at 11:11:56ID: 25045459

mrjoltcola,
Thanks a lot. I was able to remove the archive log remotely. Great. One more question, is there any way to remove them silently? Now something like
---------------
Do you really want to delete the above objects (enter YES or NO)? yes
---------------
Really need human intervention. Thanks in advance.

 

 

by: mrjoltcolaPosted on 2009-08-07 at 11:15:27ID: 25045496

Yes, use "noprompt"

delete noprompt ...
