How to delete old archived logs

hai i am running oracle 9i in archive log mode
my disk is about 90% full
pls tell me how to delete archive logs that are very older

Hi Rajeskm,
First of all, archives should not be deleted, depending your backup policie, you can need them in a recovery. But if you want delete them, do:
find <log_archive_dest>/ -name *.rdo (or extention used by you) mtime +<days ago> -exec rm{}\
Explanation:
Find -- The first, and most obvious, use is find's ability to locate old, big, or unused files, or files that you forgot where they are.
mtime -- The mtime--modify time--is the time when the actual contents of a file was last modified. This is the time displayed in a long directoring listing (ls -l).
rm -- Deletes a file without confirmation (by default).

*HOW TO DELETE THE ARCHIVE LOGS ON THE STANDBY*

HOW TO DELETE THE ARCHIVE LOGS ON THE STANDBY
I have set the RMAN CONFIGURE ARCHIVELOG DELETION POLICY TO APPLIED ON STANDBY; on my physical standby server.
My archivelog files are not deleted on standby.
I have set the CONFIGURE ARCHIVELOG DELETION POLICY TO NONE; # default on the Primary server.
I've checked the archivelogs with the FRA and they are not beign deleted on the STANDBY. Do I have to do something for the configuation to take effect? Like run a RMAN backup?
I've done a lot ofresearch and i'm getting mixed answers. Please help. Thanks in advanced.

Setting the Policy will not delete the Archive logs on the Standby. ( I found a thread where the Data Guard product manager says "The deletion policy on both sides will do what you want" ). However I still
like to clean them off with RMAN.
I would use RMAN to delete them so that it can use that Policy are you are protected in case of Gap, transport issue etc.
There are many ways to do this. You can simply run RMAN and have it clean out the Archive.
Example :
#!/bin/bash
# Name: db_rman_arch_standby.sh
# Purpose: Database rman backup
# Usage : db_rman_arch_standby <DBNAME>
if [ "$1" ]
then DBNAME=$1
else
echo "basename $0 : Syntax error : use . db_rman_full <DBNAME> "
exit 1
fi
. /u01/app/oracle/dba_tool/env/${DBNAME}.env
echo ${DBNAME}
MAILHEADER="Archive_cleanup_on_STANDBY_${DBNAME}"
echo "Starting RMAN..."
$ORACLE_HOME/bin/rman target / catalog <user>/<password>@<catalog> << EOF
delete noprompt ARCHIVELOG UNTIL TIME 'SYSDATE-8';
exit
EOF
echo `date`
echo
echo 'End of archive cleanup on STANDBY'
mailx -s ${MAILHEADER} $MAILTO < /tmp/rmandbarchstandby.out
# End of ScriptThis uses ( calls an ENV) so the crontab has an environment.
Example ( STANDBY.env )
ORACLE_BASE=/u01/app/oracle
ULIMIT=unlimited
ORACLE_SID=STANDBY
ORACLE_HOME=$ORACLE_BASE/product/11.2.0.2
ORA_NLS33=$ORACLE_HOME/ocommon/nls/admin/data

There are probably ten other/better ways to do this, but this works.
other options ( you decide )

Tip I don't care myself but in some of the other forums people seem to mind if you use all caps in the subject. They say it shouting. My take is if somebody is shouting at me I'm probably going to just move away.

Data and Archive is stored in Oracle ASM
Operating System: Sun Solaris10 64bit
We have two databases.
==>db-1(Site-A db-1 is Oracle streaming with Site-B db-1,so archive logs should not be deleted which is required for oracle streaming)
==>db-2
Existing Backup and Recovery Strategy:
Daily logical backup of application schema using DATA PUMP.
We have not taken any RMAN Backup still.
Please find the status of Shared Storage.

You should consider using RMAN for backup/recovery. Logical exports (Data Pump) are useful for some purposes, but are not the preferred way to go for your backup and recovery needs. RMAN will give you better performance and so much more options.
Long-term, a great way to delete archivelog backups is via RMAN “backup archivelog …. delete input” and/or “delete archivelog … “commands.
Please delete archivelogs only after they are already backed up. RMAN will also take into consideration if the backups are needed for Streams and/or Standby.
About the backup space – a full RMAN backup is typically smaller than the size of your DB. You need to run a test to see the exact size. The frequency and type of backup should be based on your SLE for this DB.

How to delete old logs in SAP BI, what is the best way to go?

Hi,
below are the issues we are facing,
when executing infopackage job is not getting triggred into source system.
for activation DSO data it is taking huge time. At the time of seqential read to RSREQDONE table.
I think this is due to huge logs in the staandard tables.
What could be the reson behind this.. and let me know how to delete old logs.
Thanks,
Harish

Hi,
just carry out RSRV for DSO PSA tables and see if there is inconsistency available there in the PSA table.
see if the change log and PSA deletion is happening regularly..else schedule same in PC
check with basis there are certain jobs which needs to run regularly at certain frequency..

I accidently delete the archived log, how to recover?

There was old archived log file in a directory, I delete the directory, so when I backup whole archived log with RMAN, I often got error like this,
RMAN-06059: expected archived log not found, lost of archived log compromises recoverabiligy
ora-196525: error identifying file G:\oracle\oradata\archive\arc00081.001
I am using oracle 9.2 on windows XP
Edited by: user8117130 on Jun 14, 2009 9:35 PM

HI..
I delete the directory, so when I backup other archived log with RMAN, I often got error like this From metalink:-
Error:     RMAN-06059 (RMAN-6059)Text:     expected archived log not found, lost of archived log compromises
     recoverability
Cause:     The archived log was not found. The repository thinks it does
     exist. If the archived log has in fact been lost and there is no
     backup, then the database is no longer recoverable across the
     point in time covered by the archived log. This may occur because
     the archived log was removed by an outside utility without
     updating the repository.
Action:     If the archived log has been removed with an outside utility and
     the archivelog has already been backed up, then you can
     synchronize the repository by running CROSSCHECK ARCHIVELOG ALL.
     If the archivelog has not been previously backed up, then you
     should take a full backup of the database and archivelogs to
     preserve recoverability. Previous backups are not fully
     recoverable.

If you don't have the log file(s) in question, then you need to:
re-sync the databases/schema/tables, or
advance the CSN to a point in time where you do have log files and deal with missing data separately
Is an archived transaction log missing?
● Extract reads the archived logs when an online log is not available. If you started
Extract after it was stopped for a long time, the records it needs to process might
already be archived away.
● Restore the archive log that is specified in the error message in the report file, and also
restore all subsequent logs.
NOTE Extract should not be stopped for a long time. If you must stop Extract, make
certain that archives are available all the way back to the time that you stopped
Extract. If Extract remains stopped for an exceptionally long time, it might be more
practical to resynchronize the table(s) rather than wait for Extract to go through the
archives and catch up.

How to determine which archive logs are needed in flashback.

Hi,
Let's assume I have archive logs 1,2,3,4, then a "backup database plus archivelogs" in RMAN, and then archive logs 5+6. If I want to flashback my database to a point immediately after the backup, how do I determine which archive logs are needed?
I would assume I'd only need archive logs 5 and/or 6 since I did a full backup plus archivelogs and the database would have been checkpointed at that time. I'd also assume archive logs 1,2,3,4 would be obsolete as they would have been flushed to the datafiles in the checkpoint.
Are my assumptions correct? If not what queries can I run to determine what files are needed for a flashback using the latest checkpointed datafiles?
Thanks.

Thanks for the explanation, let me be more specific with my problem.
I am trying to do a flashback on a failed primary database, the only reason why I want to do a flashback is because dataguard uses the flashback command to try and synchronize the failed database. Specifically dataguard is trying to run:
FLASHBACK DATABASE TO SCN 865984
But it fails, if I run it manually then I get:
SQL> FLASHBACK DATABASE TO SCN 865984;
FLASHBACK DATABASE TO SCN 865984
ERROR at line 1:
ORA-38754: FLASHBACK DATABASE not started; required redo log is not available
ORA-38761: redo log sequence 5 in thread 1, incarnation 3 could not be accessed
Looking at the last checkpoint I see:
CHECKPOINT_CHANGE#
865857
Also looking at the archive logs:
RECID STAMP THREAD# SEQUENCE# FIRST_CHANGE# FIRST_TIM NEXT_CHANGE# RESETLOGS_CHANGE# RESETLOGS

31 766841168 1 7 865833 10-NOV-11 865857 863888 10-NOV-11
How can I determine what archive logs are needed by a flashback command? I deleted any archive logs with a SCN less than the checkpoint #, I can restore them from backup but I am trying to figure out how to query what is required for a flashback. Maybe this coincides with the point that flashbacks have nothing to do with the backups of datafiles or the checkpoints?

Script for automatic delete of archive logs/redologs

Hi Experts,
Do you have any idea on how to create a shell script. Actually the function of it, is to automatically deletes the archive logs/redologs if reaches the limit. Or is there any parameter to change to set the automatic deletion of archive logs/redologs.
Regards

Hi,
at first, archivelogs should always be saved to tape before you delete them. If you don't want to backup them, may be for a test system, you can suppress them in ORACLE instead to delete them later.
You can run the database in "NOARCHIVE LOG MODE". If you do so, the online redologs are not archived, they are still reused and overwritten. You can not run an online Backup, when the database is in noarchive log mode. If you want to backup the database, you have to run an offline backup.
Do not use the NOARCHIVE LOG MODE for production or developemet systems.
To change the archive log mode:
shutdown the database
startup mount;
alter database noarchivelog;
alter database open;
archive log list will show the actual status

Delete unwanted archive logs

We do only one way replication using stream. How do I find archive logs that can be deleted at source. Our destination runs nonarchive.

If you use RMAN - it is streams friendly and should know which logs can be purged.
Otherwise, I use the following query:
SELECT r.CONSUMER_NAME,
r.NAME,
r.FIRST_SCN,
r.NEXT_SCN,
case when (r.next_scn > c.required_checkpoint_scn) then ‘NO’ else ‘YES’ end purgable
FROM DBA_REGISTERED_ARCHIVED_LOG r, DBA_CAPTURE c
WHERE r.CONSUMER_NAME = c.CAPTURE_NAME;
According to Metalink note 373066.1 this is what RMAN does, so it should be safe.

How to set no archive log in MS SQL

Dear Gurus,
I'll already did the support package upgrade and need to run the SGEN.But before that I'll need to set the archive log in MS SQL 2005 database.
Kindly please help me,how to set "no archive log " in MS SQL .Then I can run the SGEN.After that how to revert back to "enable archive log mode".
All the posting told about the archive log with Oracle.
Thanks
/Shah

Hi Shah,
In MS SQL Server, Transaction log is used to write log files.
For eg., Intially if you allocate 10GB to the Tr.Log and can set the limit based on your requirement, say as 11GB. It means it wont grow beyond the point 11GB.
If you take a transactional log backup, the data present in the 10GB file is freed up, but the size of the file would remain same.
This can be truncated by shrinking the log file.
1. Open SQL Mgmt studio.
2. Right click on the DB(SID)> Tasks>Shrink-->Files.
3. Choose "Log" in the file type and "Log File Name" in the Filename column.
4. Shrink Action should be "Release Unused Space"
5. Then Click Ok. The unused space will be released.
The Transaction log can be switched off by changing the Recovery Model to "SIMPLE"
1. Click on the DB(SID)
2. Properties>Options>Recovery Model.
3. If the recovery model is set to Simple, the Transaction log wont be written.
Hope this would help you. Revert for any other clarification.
Regards,
Kamesh
