Purge archive logs standby database

How can I purge automaticly the archives logs in the standby database?
I have oracle versión 11.2.0.2 with +ASM in solaris.
Thanks.

My bad.
Will update my notes.
This is still there :
Applied Archivelogs Are Not Deleted On Physical Standby Site from Flash Recovery Area [ID 404338.1]
Since you have your DELETION POLICY set correctly you can also run something like this on the Standby :
run {
allocate channel for maintenance device type disk;
delete archivelog until time 'sysdate -5';
}Best Regards

Next log sequence to archive in Standby Database (RAC Dataguard Issue)

Hi All,
I just had implemented Data Guard in our server. My primary Database is RAC configured, but it is only single node. The other Instance was removed and converted it to Developement Instance. For the reason I kept the primary as RAC is when I will implement dataguard, my Primary Database is RAC with 7 nodes.
The first test is successful, and I was able to "switchover" from my primary to standby. I failed in the 'FAILOVER" test.
I restore my primary server and redo the setup.
BTW, my standby DB is physical standby.
When I try to switchover again and issue archive log list, below is my output.
SQL> archive log list;
Database log mode Archive Mode
Automatic archival Enabled
Archive destination USE_DB_RECOVERY_FILE_DEST
Oldest online log sequence 38
*Next log sequence to archive 0*
Current log sequence 38
SQL> select open_mode, database_role from v$database;
OPEN_MODE DATABASE_ROLE
MOUNTED PHYSICAL STANDBY
===============================================
SQL> archive log list;
Database log mode Archive Mode
Automatic archival Enabled
Archive destination USE_DB_RECOVERY_FILE_DEST
Oldest online log sequence 38
*Next log sequence to archive 38*
Current log sequence 38
SQL> select open_mode, database_role from v$database;
OPEN_MODE DATABASE_ROLE
READ WRITE PRIMARY
In my first attempt to switchover before I failed in "FAILOVER" test, I also issue +archive log list+ in both primary and standby database, and if I remember it right, next log sequence on both should be identical. Am I right on this?
Thanks in Advance.
Jay A

Or Am i just overthinking on this?
Is dataguard only looking for the current and oldest log sequence?

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$archived_log where archived='YES' group by thread#;
THREAD# MAX(SEQUENCE#)
1 27908
2 28476
3 31643
select max(sequence#) from gv$archived_log;
MAX(SEQUENCE#)
31643
From Standby

Any help is appreciated.
Thanks in advance.

Apply archive logs to database

I have a production database that is online. I'm planning to setup a pc with the same configurations as that of the db server and use that server as the reporting generation. The clone pc's database will be one day delay compared to the production database. I'm planning to use export/import but someone suggested to use the archive log files of the production database and apply it to the clone pc, is this doable?
I have a full export backup and all the archive log of the production database, is this enough to restore the clone pc to the state( one day back) of the production database?
Need your suggestions. Thanks

You can do this while configuring physical standby database.

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.

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.

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.

Standby creating archives log files issue!

Hello Everyone,
Working on oracle 10g R2/Windows, I have created a dataguard with one standby database, but there is a strange issue that happen, and I'll need someone to shed the light to me.
By default archived log created from the primary database should be the sent to the stanndby database, but I found that the standby database has plus one archived log file.
From the primary database:
SQL> archive log list;
Database log mode Archive Mode
Automatic archival Enabled
Archive destination C:\local_destination1_orcl
Oldest online log sequence 1021
Next log sequence to archive 1023
Current log sequence 1023
contents of C:\local_destination1_orcl
1_1022_623851185.ARC
from the standby database:
SQL> archive log list
Database log mode Archive Mode
Automatic archival Enabled
Archive destination C:\local_destination1_orcl
Oldest online log sequence 1022
Next log sequence to archive 0
Current log sequence 1023
contents of C:\local_destination1_orcl
1_1022_623851185.ARC
1_1023_623851185.ARC ---> this is the extra archive file created in the standby database, should someone let me know how to avoid this?
Thanks for your help

Have i missed any archive log in Standby setup?, im unable to find

Dear All,
I setup standby in Oracle10g.
In my Primary the archive log list shows as
primary>archive log list;
Database log mode Archive Mode
Automatic archival Enabled
Archive destination D:\STANDBY\Archive
Oldest online log sequence 30
Next log sequence to archive 32
Current log sequence 32
In my standby the archive log list shows as
standby>archive log list;
Database log mode Archive Mode
Automatic archival Enabled
Archive destination C:\PRIMARY\Archive
Oldest online log sequence 31
Next log sequence to archive 0
Current log sequence 32
Have i missed any archive log file?
But in my archive location of the primary i found the archive files from ARC00002_0633898426.001,ARC00003_0633898426.001 to ARC00031_0633898426.001
and in my archive location of the standby i found the archive files from
ARC00002_0633898426.001,ARC00003_0633898426.001 to ARC00031_0633898426.001 and one more extra archive file ARC00032_0633898426.001.
I am getting confused from where i got the archive file ARC00032_0633898426.001 in standby only which is not in primary?
Please clarify this...

Please let me know abiut the above issue, i will be thankful to you.

Online Redolog Archiving on Logical Standby Databases!!

Hi,
Can I safely stop archiving on logical standby database? It has been inherited from primary database at the time of creation, but I don't see any reason why to keep it enabled while it's consuming unnecessary disk space on our server!!
Any body can give a valid reason to keep it enabled??
Thanks

hi
u dont need archiving on standby database as standby database reads archive files that come from primary database.its simply wastage of resource.stand by database was created from primary by taking a full backup.and to apply the archive files in case of failure u need atleast 1 backup of stand by database .and i assume u wont go for taking backup of standby database.
just worry about the archives of primary database.

Database large Number of archive log

Oracle 11g
window server 2008 R2
My database working fine, from last week i have noticed that database generating large no of archive log.
Database size is 30GB
Only one table space is 16GB , other tablespaces not more 2 GB.
I can not figured out why it generating large no. of archive log. can any one help me to figure out.
previous week i have only did these changes
Drop index
create index
create new table from existing table.
nothing else i did.

Hi
As you say workload increases. See when the number of log switches goes high and take an AWR report or statspack report. Check the DML operations. Use below query to chk the log switches

One common mistake is enabling debugging. You can check in application code if any debugging is enabled. (insert every records for logging or support purpose)

To clear db2 archive log after db2 database backup

After db2 backup archive log remains as it is.is there setting to remove archive logs after database backup.DAS is not installed.
DB2 9.1 FP 6
os HP unix

Hello Anand,
If the archvied logs are not required, ie they are not required for restore
you can remove them.
You can check this is by running
db2 list history all for db <sid>
The above command will give you a detailed overview of the backup
history and what logs were archived and what logs were included or needed for restore of backups.
If they are no longer needed for a restore, then it is safe to remove them.
Kind regards,
Paul
