Deleting applied archives from standby

Hello Guys,
We have oracle 10g rel 2 on hp-ux
I feel this common question for dataguard implementation
Just want to check best way of deleting archives automatically from standby database,i have 2 methods in mind
as below
1)At os level shell script-finding last seqno from alert log at standby/or query v$views(select max(sequence#) from v$archived_log) ,passing it to script
using rman as :*delete archivelog until sequence seqno;*
or deleting at os level upto this seqno
(Making script is not issue with this functionality and scheduling it in cron)
2)by RMAN at standby
set alter system set "_log_deletion_policy"='ALL' scope=spfile;
set CONFIGURE ARCHIVELOG DELETION POLICY TO APPLIED ON STANDBY;
however i have no plans to take backup at standby,still can i use above command
is it reliable i faced some issues in past inspite of this configurations archives were not deleted at standby
Please give your views is there any other method to delete archives automatically ,and which one is more preferred
and reliable method/best method
Thanks

logdeletion_policy parameter is static, so which you cant change dynamically, PRimary should bounce, If it is fine then you can go ahead.
If you do not have time, then prepare an RMAN script to delete the archives.

How to apply archive in Standby Database?

Hello,
My Database are running in linux plateform. I am seeing that archives which are generating are not copying to standby server & not applying.
Can anybody suggest me how to copy archive from primary database(ASM file system) to standby Database & apply those archives?
Thanks

Hi,
I am having similar problem. The primary logs are shipping on to standby but are not getting applied.
Here are the outputs:
From primary
SQL > select thread#,max(sequence#) from v$archived_log where archived='YES' group by thread#;
THREAD# MAX(SEQUENCE#)
1 27908
2 28476

Is there a way to apply archive logs, standby DB is opened with 'resetlogs'

Hi All,
I have setup a standby database (Oracle 10g SE). I applied hot backup and archive logs to the standby database till yesterday. I have opened the standby database using 'alter database open resetlogs;" and validated the application functionality using the standby database.
Now I want to regularly apply logs from the Primary database to the standby database, but today I have opened the standby database using 'alter database open resetlogs;"
Need assistance to know the way to apply archive logs, once the standby database is opened with 'resetlogs' option to keep it in sync with the Primary database.
Thanks

Welcome to OTN,
I have setup a standby database (Oracle 10g SE). I applied hot backup and archive logs to the standby database till yesterday. I have opened the standby database using 'alter database open resetlogs;" and validated the application functionality using the standby database.Standby opened with *resetlogs* ? What you did? have you performed failover of standby database?
Now I want to regularly apply logs from the Primary database to the standby database, but today I have opened the standby database using 'alter database open resetlogs;"
Need assistance to know the way to apply archive logs, once the standby database is opened with 'resetlogs' option to keep it in sync with the Primary database.Have you enabled Flashback & created Restore point? If so you can do it.. If not rebuild standby again.

Regarding deletion of archives from asm

Dear Gurus
I want to delete archivelogs from ASM and want to schedule a script for same in crontab.Please tell me the way for same.
Also i removed archives manually from asmcmd.But when i runned below command,i didn't observed any change in the free_space.
select total_mb,free_mb,(total_mb-free_mb) used from v$asm_diskgroup;
Regards

First of all: always, always include your four digit Oracle version and platform information,
Moreover, crontab is a paleolithic tool, which you don't need as there is a more powerful scheduler in both database control and the database itself.
But more importantly: One doesn't remove archivelogs using OS commands, as that will make RMAN backups don't function correctly anymore.
You need
delete obsolete archivelog all
in RMAN
Doing so, the RMAN catalog in your controlfile and the OS will be consistent.

Standby database Error in applying archives

Hi All
Environment:
Oracle 8i
Platform- HP-UX
I have production database on HPUX box and standby database on anothe HPUX box.
I am applying archive to standby everyday manually.
In last week, I have added ney datafile webapp03 in Production database tablespace.
When I apply archive to standby database. It says archive apply sucessfully but give below warning:
ORA-01547: warning: RECOVER succeeded but OPEN RESETLOGS would get error below
ORA-01195: online backup of file 25 needs more recovery to be consistent
ORA-01110: data file 25: '/u06/oradata/vestcom/webapp03.dbf'
Yesterday I have copied datafile from production to standby database.
But still I am getting same warning:
Please let me know in detail, I am totally new in this admin field.
Please help me out for this issue:
Thanks in Advance.
R M

Absolutely. First place the tablespace space in backup mode, then copy over the datafile and then end the backup mode - applying the log files should be fine now.

Thanks

Archives from PRD to DR

Hi All,
Our SAP System:
ECC 6.0
Windows 2003
Oracle DB 10.2.0.4
We started our DR 1 month before and started patching it. as DR is UP and all Patches are successfully applied. We want to shift our users from PRD to DR and want to patch the PRD.
How can I apply archives from PRD to DR as our DR has one month old Productiion data. After then we will be able to shift users to DR. And when patching is done on PRD, we will shift them back to PRD and continue the DR as it is.
Please help how can i complete the task above.
Regards,
Diya.

Hi Diya,
As Sunny and Orkun mentioned, the archivelogs cannot be applied in DR/standby once the DB is opened. In your case you have already opened the DB in DR and hence you will not be able to apply the archivelogs now.
FYI: No need to apply the patches (SAP support packages) seperately in DR. Instead you can apply the patches in PRD and DR will be updated with patches/changes while you recover the archive logs.
You can follow the below mentioned steps to create a standby DR.
1. Backup the PRD DB (offline backup)
2. Stop the application and DB in the DR site
3. Restore the backup in DR using BRRESTORE
4. Create a standby controlfile in PRD and copy the same to the controlfile locations in DR
5. Start the DB at the DR site in the standby mode
6. Copy the archive logs (you can either do this manually or automate the same usnig oracle dataguard)
7. Apply/recover the archive logs in the DR (ongoing process).
(or)
1. Copy the datafiles from PRD
2. Create a standby controlfile in PRD and copy the same to the controlfile locations in DR
3. Start the DB at the DR site in the standby mode
4. Copy the archive logs (you can either do this manually or automate the same usnig oracle dataguard)
5. Apply/recover the archive logs in the DR (ongoing process).
Hope this helps/clarifies.

*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

Archive sequence number from standby does not match primary

I have two unix servers configured, one as primary and one as standby, both in 11.2.0.2. When I run the verification scripts, I noticed that my standby's archive log sequence does not match the primary.
From standby:
select database_role, open_mode from v$database; Result: PHYSICAL STANDBY, MOUNTED
select max(sequence#) from v$archived_log; Result is null
archive log list;Database log mode Archive Mode
Automatic archival Enabled
Archive destination /arch/standby
Oldest online log sequence 0
Next log sequence to archive 0
Current log sequence 0

Hello;
I don't think you have Data Guard working.
select max(sequence#) from v$archived_log; This should return a number.
Do an alter system switch logfile; on the primary, I'm thinking the new log never makes it to your standby.
Once you have this working consider running something like this from your Primary:
SELECT name as STANDBY, SEQUENCE#, applied, completion_time from v$archived_log WHERE DEST_ID = 2 AND NEXT_TIME > SYSDATE -1;
select max(sequence#) from v$archived_log where NEXT_TIME > sysdate -1;
You can change the first query to include both the Primary and the Standby.

CONFIGURE ARCHIVELOG DELETION POLICY TO APPLIED ON STANDBY;
on Standby:
RMAN> SHOW ARCHIVELOG DELETION POLICY;
RMAN configuration parameters are:
CONFIGURE ARCHIVELOG DELETION POLICY TO NONE;
I would like to delete the archivelogs from Primary(as soon as they are applied to standby) as well as from standby and schedule a RMAN script which will run every hourly. The archivelogs are taken on flashback area.
Please guide.

What do you mean by that? Do you mean you deleted photos or albums from your iPhoto Library?
You best solution is to use Time Machine to restore your library from just before you "cleaned your iPhoto archive".
