Automatically Deleting Flashback logs

Hi all,
Platform: oracle 10g R2, Win 2003 server
Is there a way someone can delete flashback logs automatically without doing it the normal way?
The normal way: startup nomount
alter database flashback off;
My manager said I can keep on shutting down the database, he wants it done automatically.
Any help please???
Thanks.

Hi,
Set the parameter DB_FLASHBACK_RETENTION_TARGET initialization parameter which determines exactly how far a database can be flashed back. The default value is 1440 minutes (one full day), but this can be modified to suit the needs of your database.

Delete flashback log dynamically.

i want to delete flashback log dynamically.
suppose today is 1st feb while running shell script it will remove flashback log 31stjan ...
i have set retention policy 1 days.
following is the my sh script
=====================
#!/bin/sh
# Daily Backup
. oraenv.oratest
export NLS_DATE_FORMAT="Dy DD-Mon-YYYY HH24:MI:SS"
LOG_DIR="/var/log/oracle"
LOG_FILE="$LOG_DIR/$ORACLE_SID-daily-backup.log"
EMAIL_TO="[email protected]"
echo -e "\nBackup Commenced: " $(date) "\n"
pushd $HOME/rman
rman target / cmdfile="daily-backup.rman" log="$LOG_FILE" append
retcode=$?
if [ "$retcode" -ne "0" ]; then
echo -e "\n***\n*** BACKUP FAILURE: Database $ORACLE_SID on $HOSTNAME \n***"
mail -s "BACKUP FAILURE: Database $ORACLE_SID on $HOSTNAME" $EMAIL_TO < $LOG_FILE
exit 1
else
mail -s "INFO: Backup success: $ORACLE_SID on $HOSTNAME" $EMAIL_TO << EOF
Database $ORACLE_SID on $HOSTNAME backed up successfully.
EOF
fi
popd
echo -e "\nBackup Completed: " $(date) "\n"
rman script
run {
# Remove any obsolete files prior to backup
crosscheck backupset;
crosscheck copy;
delete noprompt obsolete;
delete noprompt expired backup;
delete noprompt expired copy;
# Incremental backup and update of current image copy
allocate channel oem_disk_backup device type disk;
recover copy of database with tag 'ORA\$OEM_LEVEL_0';
delete noprompt obsolete;
delete noprompt expired backup;
delete noprompt expired copy;
backup incremental level 1 cumulative copies=1 for recover of copy with tag 'ORA\$OEM_LEVEL_0' database;
# Following backup - remove any now-obsolete files
delete noprompt obsolete;
delete noprompt expired backup;
delete noprompt expired copy;

RMAN cannot delete flashback logs, these are maintained automatically according to parameter 'db_flashback_retention_target'. Don't confuse FLASHBACK DATABASE with RMAN point-in-time recovery.
RMAN backups become obsolete as soon as no longer needed to meet the defined retention policy, 'delete obsolete' will never delete flashback logs.

Problem with deleting Flashback logs

Hi all,
I configured flashback database on my Oracle10g R2 DB that sits on Win 2003 server.
When I issued the command to delete the flashback logs I see that the logs are not deleted.
Please what could be the problem here?
Regards,
Creems

Sorry, I should be clearer.
My flashback retention target is 1 day - 1440 ... but that doesnt get deleted automatically, ERROR from Oracle so I hear.
So, I tried to do it manually by putting the DB in mount state and issuing:
ALTER DATABASE FLASHBACK OFF;
Yet never get deleted.
What could the problem be?
Thanks.

Want to delete out.log files

Log files having a file name of {servername}-out
n.log (where
n is a numeric identifying separate log files) accumulate in
great numbers in the folder, \JRun4\logs\. Some log files appear to
expand beyond their typical 200kb size into the hundreds of
megabyte range. We're looking for a solution that will
automatically delete these log files before they accumulate beyond
control.
What might be available to handle this, such as a solution
that will delete old log files after a certain limit is reached?
We are running CF MX 7.02 on Window 2003 OS.

Oracle not using space occupied by flashback logs

Hi,
oracle 10g R2 10.2.0.1 on RHEL 4 64-bits.
my db_flashback_retention_target is set to 1440 and my db_recover_file_dest_size is set to 40G.
flashback logs are occupying about 36G so whenever rman tries to backup the database, it breaks saying it cannot reclaim enough space from the 40G limit.
when checking the flashback logs,i saw that the DB is keeping 3 day old logs. should it not reclaim the space occupied by these logs and delete them?

Others have reported similar issues: http://www.wayneadamsconsulting.com/
>
One thing that I have not seen the database do, however, is delete reclaimable flashback logs in order to make room for a backup. If there is not enough free space in you FRA for a backup but there is plenty of space used by relcaimable flashback logs, RMAN and the database will not delete flashback logs to free up room in the FRA for the backup. This seems like a fairly large gap in the flashback log functionality, but hopefully Oracle will handle it in a future release.
>
See MOS note: Space issue in Flash Recovery Area( FRA ) [ID 829755.1] .
Note also that 10.2.0.1 is a old 10.2 release and that you could consider upgrading to 10.2.0.4.

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

Automatic Deletion of Files in FRA

Ok, I am about fired up right now. I have read over and over how Oracle will reclaim space in the FRA if it is running low yet I can't reproduce this behavior to save my life.
- I have archive logging enabled.
- I am using the FRA.
- I have a recovery window of 1 day set.
- I have full incremental (level 0) backups for the past three days.
- I am also backing up archivelogs and have "all not backed up" specified as well.
"report obsolete" does indeed report the backups that fall outside of my recovery window correctly. When I run another backup I receive the following:
ORA-19809: limit exceeded for recovery files
ORA-19804: cannot reclaim 9163505664 bytes disk space from 16106127360 limit
All I have at this moment is a strong desire to repeat the word "derp" over and over. Can someone explain what I am missing (or perhaps misconstruing) or point me at some docs that clearly spell this out for me?
Or is it simply that what is being stated implies that I run the following to cause Oracle to "automatically delete files" to create space for new FRA additions:
allocate channel for maintenance type disk;
delete noprompt obsolete device type disk;
release channel;
Cheers!

Alrighty then... I think this paints the appropriate picture:
select file_type, space_used*percent_space_used/100/1024/1024 used, space_reclaimable*percent_space_reclaimable/10 /1024/1024 reclaimable, frau.number_of_files from v$recovery_file_dest rfd, v$flash_recovery_area_usage frau;
FILE_TYPE                  USED RECLAIMABLE NUMBER_OF_FILES
CONTROL FILE                  0           0               0
REDO LOG                      0           0               0
ARCHIVED LOG          8277.5077           0              36
BACKUP PIECE           3864.931    2938.875              13
IMAGE COPY                    0           0               0
FLASHBACK LOG                 0           0               0
FOREIGN ARCHIVED LOG          0           0               0
7 rows selected.So it appears that I cannot create new backups due to the Archived Logs being ineligible for space reclamation and NOT the backupsets.
Edit: I shall now work on recreating my test scenario (appropriately).

Flashback log purge

Hi
I`ve set db_recovery_file_dest_size to 20m and flashback retention target to 60mins.
As far as I know flashback logs are automatically deleted when the fra is filled up.
I notice that there are 4 flashback logs and they are never deleted in the last two days.
What is the reason for that ?
log_1.287.760141739
log_2.281.759973635
log_2.285.760141745
log_3.298.760145161

It only possible it will reuse it.
Most of the time it will create a new log from my experience.
It all depends on your settings.
I watch v$flash_recovery_area_usage fairly close on my systems and the flashback logs are a fairly small piece of my FRA.
Archive and RMAN backups use up most of the space. For the most part I let Oracle just handle the flashback logs.
Best Regards
mseberg

Which function module to delete job log?

Hi, I submit report via jobname and jobcount. After I close job and run it, we can see jobname is still in job log by SMX. But client doesn't want to see it, so who can kindly tell me which function module can delete jobname from job log?
Thanks a lot.
Jack

try CALL FUNCTION 'BP_JOB_DELETE'
If you have used JOB_OPEN before the SUBMIT to create the job, you can automatically delete the job upon successful completion by setting the parameter DELANFREP = 'X' in the JOB_OPEN function call.. this way the user will only see the logas for cancelled/aborted jobs..

My e-mail automatically deletes read e-mail in my inbox every 14 days without my permission. How do I get this to stop?

I switched e-mail clients from windows live to thunderbird in mid december to alleviate problems in sending group e-mail. I have thunderbird on a different laptop and the product works flawlessly. The client works flawlessly with one exception: It automatically deletes any read e-mail in my inbox every 14 days without any input from me. I have had ITOK & Hughes.net look at the problem as I am using my inbox as a staging area for for pending business that tracks progress of different events. I have checked settings and there are no evident features that I can switch on or off with that time frame. This has occurred 3 times since December and I have resorted to printing e-mails to prevent loss of data.
The desktop uses windows 7, IMAP for incoming mail...

Log into your account at the providers web mail page and look for any retention options that might be there. Do not put too much into what their help desk tells you. Most help desk agents are lucky to know that the ringing sound means to answer the phone.

Automatic deletion of old archive files and trace files

I've got a database that must run 24x7 without being monitored by a DBA.
Two questions:
1. Is it possible to get Oracle to automatically delete and uncatalog old archive files?
2. Is it possible to get Oracle to automatically delete old trace files located in udump and bdump?
Thanks in advance

1. When you say 'uncatalog old archives do you mean that your database is backed up using RMAN and a catalog? If this is the case then RMAN can delete the backed up archives for you. Just add 'delete input' to the end of the 'backup archive log...' line in your backup script.
2. Oracle can't delete the trace files. Best way is to write a script that delete all files older than X days and schedule it to run every night.

How to delete archive log on standby site

hi
i configured dataguard on 10g. could anyone suggest how to delete archived log on standby site..

Hi,
There is no automatic feature out-of-the-box but you have the following views:
1) Shows archive logs transfered:
select sequence#, first_time, next_time from v$archived_log order by sequence#;
2) Shows archive logs applied:
select sequence#, archived, applied from v$archived_log order by sequence#;
If you see your archivelogs applied you can safely remove archive log files from your disk. It is your decision if you keep or delete them completely.

How to delete archive logs on the standby database....in 9i

Hello,
We are planning to setup a data guard (Maximum performance configuration ) between two Oracle 9i databases on two different servers.
The archive logs on the primary servers are deleted via a RMAN job bases on a policy , just wondering how I should delete the archive logs that are shipped to the standby.
Is putting a cron job on the standby to delete archive logs that are say 2 days old the proper approach or is there a built in data guard option that would some how allow archive logs that are no longer needed or are two days old deleted automatically.
thanks,
C.

Check this note.
*Configure RMAN to purge archivelogs after applied on standby [ID 728053.1]*
Still it is on 9i, So you need to schedule RMAN job or Shell script file to delete archives.
Before deleting archives
1) you need to check is all the archives are applied or not
2) then you can remove all the archives completed before 'sysdate-2';
RMAN> delete archvielog all completed before 'sysdate-2';
As per your requirement.
