Archive logs to standby showing odd behavior.

10.2.0.2
HP 11.23
I'm monitoring the archive log transfer of files, and it appeared a little odd...as if the the files are not being applied.
So log into the system manually, and ran:
recover managed standby database cancel;
returned with recovery complete.
THen I issued:
recover managed standby database until cancel;
It asked for the files. I ran AUTO....it did it's thing, each one individually responding that
ORA-00279: change 7313758876671 generated at 04/24/2009 18:54:51 needed for
thread 1
ORA-00289: suggestion : /oraarch/swesc/peregrine_1_21380_640853326.arc
ORA-00280: change 7313758876671 for thread 1 is in sequence #21380
ORA-00278: log file '/oraarch/swesc/peregrine_1_21379_640853326.arc' no longer
needed for this recovery
Showing that it was successfully going through each archive file, applying it.
It did this until it looked for the next file that didn't exist.
This leaving the final log as 21393.
Then I issue an archive log list...
it shows 21357!
What is going ON?!

I ran archive log list on both systems to get that information.
after applying all the archive logs from the primary, the standby still showed the same sequence as it did to prior to recovery.
The recovery completed successfully, but archive log list doesn't show any change.
Meaning that before the recovery was run, it was 21357, after recovery was finished, it SHOULD have ready 23193, but it still read 21357.

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.

Archive log registered,but showing as not applied in standby db + oracle 9i

Hi all,
In my standby database some of the archive log files are not applied.found through the following command
SQL > select sequence#,applied from v$archived_log where applied='NO';
sequence# APP FIRST_TIME
18425 NO 05-FEB-10
but when try to register manually
SQL > alter database register logfile '/disk12/arch/A00123000018425.arc';
ERROR at line 1
ORA-16089:archive log has already been registered.
"recover standby database" also asking for the new archive file. how will i apply that?
any solutions?

user11919409 wrote:
I have did that so many times from 05-feb-10 onwards.
even then only one archive gap???
or only one is not applied? if yes may be archive file which exist at standby may be corrupt try to restore it from backup and recover.
also check for some clues at logs at standby and primary.. what actually happen. if archive gap is huge and you have all archvies then you may have to do manual recovery then keep it back to auto recovery mode.
Hope that may help you.

Archived log to standby server stopped

Hi,
I configured dataguard standby server few weeks ago,
I set log_archive_dest_2='SERVICE=JHRD0107_OFS1 OPTIONAL'
and log_archive_dest_state=ENABLE in primary server,
and very go fine until yesterday, I shutdown my standby server and set the log_archive_dest_state=DEFER,
when I tried to startup again the standby server, and set log_archive_dest_state=ENABLE again,
the archive stop sending the archived log to log_archive_dest_2.
No error was found in alert log of primary and standby server.
It seem that the primary server don't know there is another archive destination..
The database version is 10g 10.2.0.4
Anyone what could be the cause of this?
Thanks

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.

Manually apply archived log to standby database.

Hi all,
I am working on oracle 10g EE(10.2.0.4).I am having a very difficult database switchover case in my hand.
1.> There are two database .one primary(prim) and another standby(standby).
2.> Initially both of them was configured as oracle data guard, where prim was primary and standby was standby using rman .(RMAN>duplicate target database for
standby dorecover).
3.>But the rate of generation of archivelog is very high( 20 archivelog per hour with 200mb each).
4.> So automatic shipping of archivelog has been disabled from primary.(log_archive_dest_state_2=defer and nullifying the value of log_archive_dest_2).
5> Now after a period of time archived logs are shipped to dr site manually and applied manually.(alter database recover automatic standby database;)
6.> Now there is a hardware problem occured at primary..it will take 72 hours to come up.
How can i use standby database as primary for that 72 hour.As archive log apply is manually done and parameters are being changed,can i switch over these two?
Is it possible to switchover and switch back these two database with such a configuration?

As of now you can perform failover your standby to primary database. you should have flashaback enabled, so you have to create a restore point.
Then it can be opened in read & write mode, So once you finished again you can go back to that point.
http://docs.oracle.com/cd/B19306_01/server.102/b14239/manage_ps.htm#i1017111
The above case applicable if you ready to loose, But it doesnt make sense. But in your case this doesnt work. Because once you start use of Standby as primary, there would be live/production data, which you need very much.
So there is lot of work to do.
You have to rebuild standby database and then switchover back to same location. So its a little trip work.
Have you enabled Dataguard Broker ?

You do not point to the standby database from your primary, in order to get the archivelogs transfered. You need to set at least the parameter LOG_ARCHIVE_DEST_2 like this:
SQL>alter system set LOG_ARCHIVE_DEST_2='SERVICE=stdby VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=stdby';stdby has to be resolved by the tnsnames.ora on the primary server. Have a look here:
http://download.oracle.com/docs/cd/B19306_01/server.102/b14239/create_ps.htm#i67520
That explains all you need to do to create a physical standby briefly.
Kind regards

Best way of deleting archive logs on standby when backup taken on primary

Hello,
I have a 11gr2 dataguard configuration without the broker.
main problem in my particular situation arises from my FRA size on primary much more than on standby (90Gb vs 30Gb) and in some situations I'm constrained with FRA space on standby.... I'm going to align the FRAs but in the mean time....
can anyone confirm that if I have configuration as in subject with maximum performance mode and I'm not using the broker I should consider a sort of "external" way for archive log deletion on the physical standby?
In fact I'm setting on primary
- retention policy = redundancy 1
- archivelog deletion = applied on standby (without using any "backed up...." option)
Considering the standby it seems from docs that:
- retention policy always wins over deletion policy (so no archive eligible for deletion is deleted if retention is not satisfied)
- I can set on standby archivelog deletion = applied on standby (without using any "backed up...." option)
But it is not clear to me the effect of this config in case this is a standby itself and without any other cascade standby databases
The manual says this has to be met:
1) The archived redo log files have been applied to the required standby databases.
---> what does this mean in case the db is a standby.. met or not met as I have no other cascade standby dependant on this one?
2) The logs are not needed by the BACKED UP ... TIMES TO DEVICE TYPE deletion policy. If the BACKED UP policy is not set, then this condition is always met.
---> I should be ok
So the last question for standby is
- what to set retention policy to?
I have not understood if I set it to "NONE", this means no retention at all or retention for ever....
sometimes I read that there is no policy; in other examples that files will be retained forever (because no file considered as obsolete).... or at least so I understood...
I would like to have a sort of policy on standby where the archive logs can be deleted as soon as they are applied during the continuous media recovery phase...
It seems I can't find a self contained set of configurations across the dataguard....
Thanks in advance.
Gianluca

I agree with you.... It is a temporary contingency....
I already stressed the fact that sizes between sites must be quite identical...
we are going towards a production dataguard, migrating from a windows config (without it) to a Linux based config....
but this contingency made me think about these considerations regarding policies and automatic dataguard operations
I also stressed on equal size grow capability for both sites file systems, also for data tablespaces, so that for example in case of high fragmentation we have to avoid a limit situation where
1) a file system full for DR datafiles causes abend of automatic media recovery
2) this generates FRA growth in DR because archive logs are shipped but not applied any more
3) FRA goes 100% in DR and primary cannot ship any more
4) archive logs cannot be automatically deleted on primary because not already shipped
5) FRA full on primary and DB hangs....
Thanks anyway for input

Change the location of Archive Logs on standby Server

Can somebody tell me the process how to change the archive logs location for the standby by server. e.g. Its going now to location C:\stby\archives and I want to send it to E:\stby\archives
Thx

Hi,
Change the STANDBY SPFILE/PFILE Value of <b>standby_archive_dest=E:\stby\archives</b>

BLOBS and archive logs and standby

Hi,
1-are the informations about BLOBS registered in archivelogs ?
2-is there any issus for dataguard standby if there are BLOBS in primary DB ?
Many thanks.

Hi,
Upto my understanding BLOBS are registered.There wont be any impact on the standby database.

How: Script archive log transfer to standby db

Hi,
I’m implementing disaster recovery right now. For some special reason, the only option for me is to implement non-managed standby (manual recovery) database.
The following is what I’m trying to do using shell script:
1.     Compress archive logs and copy them from Primary site to Standby site every hour. ( I have a very low network )
2.     Decompress archive logs at standby site
3.     Check if there are missed archive logs. If no, then do the manual recovery
Did I miss something above? And I’m not skill in to build shell scripts, is there any sample scripts I can follow? Thanks.

Hi,
Take a look at data guard packages. There is a package just for this purpose: Bipul Kumar notes:
http://www.dba-oracle.com/t_oracledataguard_174_unskip_table_.htm
"the time lag between the log transfer and the log apply service can be built using the DELAY attribute of the log_archive_dest_n initialization parameter on the primary database. This delay timer starts when the archived log is completely transferred to the standby site. The default value of the DELAY attribute is 30 minutes, but this value can be overridden as shown in the following example:
LOG_ARCHIVE_DEST_3=’SERVICE=logdbstdby DELAY=60’;"
1. Compress archive logs and copy them from Primary site to Standby site every hour.Me, I use tar (or compress) and rcp, but I don't know the details of your environment. Jon Emmons has some good notes:
http://www.lifeaftercoffee.com/2006/12/05/archiving-directories-and-files-with-tar/
2. Decompress archive logs at standby siteSee the man pages for uncompress. I do it through a named pipe to simplify the process:
http://www.dba-oracle.com/linux/conditional_statements.htm
3. Check if there are missed archive logs.I keep my standby data in recovery mode, and as soon as the incoming logs are uncompressed, they are applied automatically.
Again, if you don't feel comfortable writing your own, consider using the data guard packages.
Hope this helps. . .

Physical standby in archive log mode

HI ,
Our phyiscal standby database is running in archive log mode,
1.Is it manadatory to have it in archive log mode ?
2.As it is in archive log mode , does it produce any archivelog ?

Hello again;
The Standby is a clone of the Primary. I assume we are talking Physical Standby.
Why does it need to produce archive in standby role?Its does not produce archive in the Standby role. I have seen a Standby produce a log now and then, but not log after log like a primary. A Standby database does not write Redo or use Redo logs, it uses Standby Redo logs. Since Redo logs are not used, archive is not written.
Why it is manadatory to enable archive log in standby?Smart design I'm thinking. Why would Oracle make us add this complex step to a failover/switchover?
Keep it simple if possible.

Clean of archived logs

Hi,
I recently implemented a physical standby database in 10g. I noticed that archived logs appears in the physical standby instance (the physical standby is log_archive_dest_2). I use RMAN to make backups at the principal database. Is the a way of cleaning up archived logs from standby database using RMAN connected to the principal database?

Dear user492400,
Take the archivelog backups and configure the archivelog deletion policy from none to applied on standby.
You can also connect to the standby database as target and primary database as auxiliary and run below command;
crosscheck arhivelog all;
delete noprompt expired archivelog all;Ogan
