Reasons for multiplexing archive log files
hi
I would like to try multiplexing the archive log files, but I need to explain it to my boss who is the unofficial DBA. I want to tell her that it is necessary. Are there are really convincing, compelling reasons that one would set up more than 1 archive log file destination?
Cheers.
DA
Archives are the thing that protect your data. If you have only one source for them, let's just keep our fingers crossed that nothing ever goes wrong with that source at the same time as something going wrong with the database, for then you will have lost data irrecoverably. So how much data loss is acceptable?
On the other hand, if your original archive destination uses mirrored disks and if it is backed up regularly to tape, and if daily checks that that backup has taken place successfully are made... there's an at least reasonable case to be made not to bother multiplexing the archives: you already have redundancy in depth and the additional archiving destination could well slow down the whole archiving subsystem... and that can translate into problems for LGWR and hence foreground waits suffered by users.
Nevertheless, it is true that assuming you back up your archives nightly, there is always going to be a days'-worth of archives which haven't been backed up yet. Should anything nasty happen to those, you will not be in a completely recoverable position ...and I have seen both parts of a mirrored drive die at about the same time, so that's no guarantee!
If you or your colleague don't mind losing a day's work or if you are betting people and don't mind taking a punt on hardware not failing, then not multiplexing archives is a fair judgement call to make. But if you cannot afford any data loss at all and you want to make sure that it's as guaranteed as you can get that you won't, then multiplexing archives is pretty essential.

Are there any possible reason RMAN generates some corrupt archive log files
Dear all,
Are there any possible reason RMAN generates some corrupt archive log files?

current log archived
After that I go to archive log directory "/u02/oracle/uat/uatdb/9.2.0/dbs" and use ls -lt command to see how many archive logs and my screen just hang. After we found out that we cannot use ls -lt command to read arch1_171.dbf
archive log, the rest of archive logs able to use ls -lt command.
We cannot delete this file as well. We shutdown database abort and perform check disk...... and fix the disk error and then open database again. Everything seems back to normal and we can use ls -lt command to read arch1_171.dbf.
The strange problem is we have the same problem in Development and Production..... one ore more archive logs seems to be corrupted under the same directories /u02/oracle/uat/uatdb/9.2.0/dbs.
Does anyone encounter the same problem?

"recover database until cancel" asks for archive log file that do not exist
Hello,
Oracle Release : Oracle 10.2.0.2.0
Last week we performed, a restore and then an Oracle recovery using the recover database until cancel command. (we didn't use backup control files) .It worked fine and we able to restart the SAP instances. However, I still have questions about Oracle behaviour using this command.
First we restored, an online backup.
We tried to restart the database, but got ORA-01113,ORA-01110 errors :
sr3usr.data1 needed media recovery.
Then we performed the recovery :
According Oracel documentation, "recover database until cancel recovery" proceeds by prompting you with the suggested filenames of archived redo log files.
The probleme is it prompts for archive log file that do not exist.
As you can see below, it asked for SMAarch1_10420_610186861.dbf that has never been created. Therefore, I cancelled manually the recovery, and restarted the database. We never got the message "media recovery complete"

When restaring the database we could see that, a recovery of online redo log has been performed automatically, is it the normal behaviour of a recovery using "recover database until cancel" command ?

Thank you very much for your help.
Frod.Hi,
Let me answer your query.
=======================
Your question: While performing the recovery, is it possible to locate which online redolog is needed, and then to apply the changes in these logs
1. When you have current controlfile and need complete data (no data loss),
then do not go for until cancel recovery.
2. Oracle will apply all the redologs (including current redolog) while recovery
process is on.
3. During the recovery you need to have all the redologs which are listed in the view V$RECOVERY_LOG and all the unarchived and current redolog. By querying V$RECOVERY_LOG you can find out about the redologs required.
4. If the required sequence is not there in the archive destination, and if recovery process asks for that sequence you can query V$LOG to see whether requested sequence is part of the online redologs. If yes you can mention the path of the online redolog to complete the recovery.
Hope this information helps.

Madhukar -
Problem about space management of archived log files
Dear friends,
I have a problem about space management of archived log files.
my database is Oracle 10g release 1 running in archivelog mode. I use OEM(web based) to config all the backup and recovery settings.
I config "Flash Recovery Area" to do backup and recovery automatically. my daily backup schedule is every night at 2:00am. and my backup setting is "disk settings"--"compressed backup set". the following is the RMAN script:
Daily Script:
run {
allocate channel oem_disk_backup device type disk;
recover copy of database with tag 'ORA$OEM_LEVEL_0';
backup incremental level 1 cumulative copies=1 for recover of copy with tag 'ORA$OEM_LEVEL_0' database;
the retention policy is the second choice, that is "Retain backups that are necessary for a recovery to any time within the specified number of days (point-in-time recovery)". the recovery window is 1 day.
I assign enough space for flash recovery area. my database size is about 2G. I assign 20G as flash recovery area.
now here is the problem, through oracle online manual, it said oracle can manage the flash recovery area automatically, that is, when the space is full, it can delete the obsolete archived log files. but in fact, it never works! whenever the space is full, the database will hang up! besides, the status of archived log files is very strange, for example, it can change "obsolete" stauts from "yes" to "no", and then from "no" to "yes". I really have no idea about this! even though I know oracle usually keep archived files for some longer days than retention policy, but I really don't know why the obsolete status can change automatically. although I can write a schedule job to delete obsolete archived files every day, but I just want to know the reason. my goal is to backup all the files on disk and let oracle automatically manage them.
also, there is another problem about archive mode. I have two oracle 10g databases(release one), the size of db1 is more than 20G, the size of db2 is about 2G. both of them have the same backup and recovery policy, except I assign more flash recovery area for db1. both of them are on archive mode. both of nearly nobody access except for the schedule backup job and sometime I will admin through oem. the strange thing is that the number of archived log files of smaller database, db2, are much bigger than ones of bigger database. also the same situation for the size of the flashback logs for point-in-time recovery. (I enable flashback logging for fast database point-in-time recovery, the flashback retention time is 24 hours.) I found the memory utility of smaller database is higher than bigger database. nearly all the time the smaller database's memory utility keeps more than 99%. while the bigger one's memory utility keeps about 97%. (I enable "Automatic Shared Memory Management" on both databases.) but both database's cup and queue are very low. I'm nearly sure no one hack the databases. so I really have no idea why the same backup and recovery policy will result so different result, especially the smaller one produces more redo logs than bigger one. does there anyone happen to know the reason or how should I do to check the reason?
by the way, I found web based OEM can't reflect the correct database status when the database shutdown abnormally. for example, if the database hang up because of out of flash recovery area, after I assign more flash recovery area space and then restart the database, the OEM usually can't reflect the correct database status. I must restart OEM manually to correctly reflect the current database status. does there anyone know in what situation I should restart OEM to reflect the correct database status?
sorry for the long message, I just want to describe in details to easy diagnosis.
any hint will be greatly appreciated!
Sammythank you very much, in fact, my site's oracle never works about managing archive files automatically although I have tried all my best. at last, I made a job running daily to check the archive files and delete them.
thanks again. -

Multiplexing Redo Log Files question
If you are running RAC on ASM on a RAID system, is this required? We are using an HP autoraid which mirrors at the block level and in the documentation about Multiplexing Redo Log Files it says that you do it to protect against media failure. The autoraid that we are using gives us multiple levels of redundancy against media failure so I was wondering if Multiplexing would be adding more overhead than is needed. Thanks for your input.
ASM is quite compex and I'm not going to outline all the advantages or reasons for ASM, but under ASM you can drop and add devices to maintain your capacity needs online without loosing data, which you cannot do using RAID, which requires a re-initialize, for example, regardless of redundancy. Please see the documentation. ASM, like pretty much everything Oracle will add complexity and you will have to check your requirements. ASM is however pretty much the standard. If you use external RAID, make sure your storage is not using RAID 5 or 0. Regarding logical errors, you could for example overwrite or delete a file by mistake, in which case file redundancy does not protect you. If you are looking for reasons or ways not to use ASM, I'm sure you will find them, but what's the point?

I have one problem with Data Guard. My archive log files are not applied.
I have one problem with Data Guard. My archive log files are not applied. However I have received all archive log files to my physical Standby db
I have created a Physical Standby database on Oracle 10gR2 (Windows XP professional). Primary database is on another computer.
In Enterprise Manager on Primary database it looks ok. I get the following message Data Guard status Normal
But as I wrote above the archive log files are not applied
After I created the Physical Standby database, I have also done:
1. I connected to the Physical Standby database instance.
CONNECT SYS/SYS@luda AS SYSDBA
2. I started the Oracle instance at the Physical Standby database without mounting the database.
STARTUP NOMOUNT PFILE=C:\oracle\product\10.2.0\db_1\database\initluda.ora
3. I mounted the Physical Standby database:
ALTER DATABASE MOUNT STANDBY DATABASE
4. I started redo apply on Physical Standby database
alter database recover managed standby database disconnect from session
5. I switched the log files on Physical Standby database
alter system switch logfile
6. I verified the redo data was received and archived on Physical Standby database

Please help me!!!!Hi,
After several tries my redo logs are applied now. I think in my case it had to do with the tnsnames.ora. At this moment I have both database in both tnsnames.ora files using the SID and not the SERVICE_NAME.
Now I want to use DGMGRL. Adding a configuration and a stand-by database is working fine, but when I try to enable the configuration DGMGRL gives no feedback and it looks like it is hanging. The log, although says that it succeeded.
In another session 'show configuration' results in the following, confirming that the enable succeeded.
DGMGRL> show configuration
Configuration
Name: avhtest
Enabled: YES
Protection Mode: MaxPerformance
Fast-Start Failover: DISABLED
Databases:
avhtest - Primary database
avhtestls53 - Physical standby database
Current status for "avhtest":
Warning: ORA-16610: command 'ENABLE CONFIGURATION' in progress
It there anybody that experienced the same problem and/or knows the solution to this?
With kind regards,
Martin Schaap -
Will RMAN delete archive log files on a Standby server?
Environment:
Oracle 11.2.0.3 EE on Solaris 10.5
I am currently NOT using an RMAN repository (coming soon).
I have a Primary database sending log files to a Standby.
My Retention Policy is set to 'RECOVERY WINDOW OF 8 DAYS'.
Question: Will RMAN delete the archive log files on the Standby server after they become obsolete based on the Retention Policy or do I need to remove them manually via O/S command?
Does the fact that I'm NOT using an RMAN Repository at the moment make a difference?
Couldn't find the answer in the docs.
Thanks very much!!
-garyHello again Gary;
Sorry for the delay.
Why is what you suggested better?
No, its not better, but I prefer to manage the archive. This method works, period.
Does that fact (running a backup every 4 hours) make my archivelog deletion policy irrelevant?
No. The policy is important.
Having the Primary set to :
CONFIGURE ARCHIVELOG DELETION POLICY TO APPLIED ON STANDBYBut set to "NONE" on the Standby.
Means the worst thing that can happen is RMAN will bark when you try to delete something. ( this is a good thing )
How do I prevent the archive backup process from backing up an archive log file before it gets shipped to the standby?
Should be a non-issue, the archive does not move, the REDO is transported and applied. There's SQL to monitor both ( Transport and Apply )
For Data Guard I would consider getting a copy of
"Oracle Data Guard 11g Handbook" - Larry Carpenter (AKA Dr. Paranoid ) ISBN 978-0-07-162111-2
Best Oracle book I've read in 10 years. Covers a ton of ground clearly.

How to restore cold backup + archived log files
Hi,
Suppose I take a cold backup on 18th. After that I have four days of archived log files. if the database crashes on 5th day, I have to restore the 18th cold back + 4 days of archived log files. How do I restore since it is a cold backup and I cant do incomplete recovery.
can I use
Recover database ( with 18th cold backup) in mount state and apply archived logs.
PrabhathThe details of how you perform forward recovery using a cold backup depends on
1- rman or manual backup
2- using current or backup control file
3- if rman, recovery catalog or no recovery catalog
4- if full database recovered or only a few files
Each of these conditions will affect what is known to Oracle and what needs to be done. For example if you restored the entire cold backup including the control file then Oracle would see a consistent database and not need to perform recovery so you would need to startup mount and tell the database to perform recovery using a backup control file. If using rman and no recovery catalog you might need to catalog some of the archived redo logs, etc....
It is advisable to consult the Backup and Recovery manuals before attempting recovery for any new scenario.

How to recover the database when some of the archive log file get deleted.
I am facing a problem with Oracle database, which is related to archivelogs.
Our development database is running in archivelog mode, but we don't have backups scheduled and have no recovery catalog.
When the database was in running condition, disk got full, so some archivelogs were deleted manually.
After this they restarted the DB, and now DB is not coming up. Errors are as follows:

Edited by: hem_Kec on Sep 7, 2008 9:07 AMHi,
Archive log files are the copies of redolog files.As redo log files are circularly overwritten,oracle generates archive log file of the corresponding redo logfiles being overwritten.So if you have a backup that dates back to 10 am in the morning and if your database creashed at 3 pm,you cannot use the redo log files alone as they have incomplete information.To completely recover the database upto 3 pm,you need archive log files generated between 10 am to 3 pm. In your case since you are missing one archive log file,you cannot perform complete recovery and hence would suffer data loss. -
Archived log file are not shifted to standby side and applied
Hi Guru's,
DB
My OS Version:Windows Server 2003
DB Version:11.2.0.1.0
I am trying to create Physical Standby DB on my test machine after setting all the parameters and start standby db in mount mode when i do the verification of archived log files that need to be shift from pri site to standby site i am getting:
no rows selected.
I am following the below mentioned doc for reference
http://docs.oracle.com/cd/E11882_01/server.112/e25608/create_ps.htm#i63561
Can anyone from your side can help me to sort out this problem.

Yes the max sequence generated on primary is same as the max sequence applied on standby.
And what is MRP and why it is important can you please let me know abt thisWhenever you created standby database, Make a habit of tail to alert log file to monitor whats happening on the standby database, Besides MRP is an Media Recovery Process , which applies archies/redo on standby database.
MRP can apply based on the redo transport, If you are using real-time apply then Redo will be writtened to the standby redo log files at the same time recovery will be performed by MRP process, If you are not using Real-Time apply then whenever a archive generated on primary that archive will be transported to the standby and applied on the standby database.
It is recommended to use Realtime apply, so that you can avoid much data lost.
However you are in 11gR2, You can use below query to monitor
SQL> SELECT * FROM V$STANDBY_EVENT_HISTOGRAM WHERE NAME = 'apply lag' AND COUNT > 0;
NAME TIME UNIT COUNT LAST_TIME_UPDATED
apply lag 0 seconds 431 08/05/2012 22:14:21

Hello,
I have a understanding problem off the function of the archived log files. My Oracle 9i Database is running in ARCHIVELOG. So if the online log files are full they get backed up to 3 different locations.
However if I view now the v$archive_log view then I see all the archived log files.
So now my questions:
1. At which point does these archived log files get deleted ?
2. If they never get deleted how do I know which archived log file can I delete.
3. If I run a full hot/cold backup can I delete this archive log files?
4. Is there any other way to delete the archived log files then using rman "delete input" option ? Like is there any way to delete the archived log files form the sqplplus prompt ?
I have searched and read some articles in the net about it but it is always just about how to set up the db into archivelog mode but I was not able to find anything answering my questions.
Thank you
MarcusOut of the box, archived logs are not deleted
automatically. However, you can delete them via
RMAN. RMAN will delete them based on the set
retention policy. You can see which logs and
backups RMAN considers obsolete via the "report
obsolete" command. RMAN keeps track of logs that
are necessary for recovery, and those that can
be safely deleted.
Another option, as you have noted, is to backup
archivelogs using RMAN, with the "delete input"
option.
The best option (IMHO) is to automate deletion
of obsolete archive logs via a script. This
can be done using the "delete noprompt obsolete"
RMAN command.
I'm not aware of any SQLPlus based method to delete
logs. In any case, this would NOT be a good idea, as
RMAN would not be aware of any such deletions.
Hope this helps.

Archived log files not registered in the Database
I have Widows Server 2008 R2
I have Oracle 11g R2
I configured primary and standby database in 2 physical servers , please find below the verification:
I am using DG Broker
Renetly I did failover from primary to standby database
Then I did REINSTATE DATABASE to returen the old primary to standby mode
Then I did Switchover again
I have problem that archive logs not registered and not imeplemented.
SQL> select max(sequence#) from v$archived_log;

I did alter system switch logfile then I ssue the following statment to check and I found same number in primary and stanbyd has not been changed
SQL> select max(sequence#) from v$archived_log;
MAX(SEQUENCE#)
16234
Any body can help please?
RegardsThanks for reply
What I mean after I do alter system switch log file, I can see the archived log files is generated in the physical Disk but when
select MAX(SEQUENCE#) FROM V$ARCHIVED_LOG;
the sequence number not changed it should increase by 1 when ever I do switch logfile.
however I did as you asked please find the result below:

Data Guard. My archive log files are not applied.
I have one problem with Data Guard. My archive log files are not applied. However I have received all archive log files to my physical Standby db
I have created a Physical Standby database on Oracle 10gR2 (Windows XP professional). Primary database is on another computer.
In Enterprise Manager on Primary database it looks ok. I get the following message Data Guard status Normal
But as I wrote above the archive log files are not applied
After I created the Physical Standby database, I have also done:
1. I connected to the Physical Standby database instance.
CONNECT SYS/SYS@luda AS SYSDBA
2. I started the Oracle instance at the Physical Standby database without mounting the database.
STARTUP NOMOUNT PFILE=C:\oracle\product\10.2.0\db_1\database\initluda.ora
3. I mounted the Physical Standby database:
ALTER DATABASE MOUNT STANDBY DATABASE
4. I started redo apply on Physical Standby database
alter database recover managed standby database disconnect from session
5. I switched the log files on Physical Standby database
alter system switch logfile
6. I verified the redo data was received and archived on Physical Standby database

Please help me!!!!Hi,
After several tries my redo logs are applied now. I think in my case it had to do with the tnsnames.ora. At this moment I have both database in both tnsnames.ora files using the SID and not the SERVICE_NAME.
Now I want to use DGMGRL. Adding a configuration and a stand-by database is working fine, but when I try to enable the configuration DGMGRL gives no feedback and it looks like it is hanging. The log, although says that it succeeded.
In another session 'show configuration' results in the following, confirming that the enable succeeded.
DGMGRL> show configuration
Configuration
Name: avhtest
Enabled: YES
Protection Mode: MaxPerformance
Fast-Start Failover: DISABLED
Databases:
avhtest - Primary database
avhtestls53 - Physical standby database
Current status for "avhtest":
Warning: ORA-16610: command 'ENABLE CONFIGURATION' in progress
It there anybody that experienced the same problem and/or knows the solution to this?
With kind regards,
Martin Schaap -

SubbuHello Subbu,
> I have taken backup yesterday monrning in Archive log mode but have lost all the archive log files.
You mean you have taken an online backup and lost all your archive log files after that online backup?
SQL> alter database open resetlogs;
Error: ORA-01113: file 1 needs media recovery
ORA-01110: data file 1: 'E:\oracle\'<SID>\sapdata1\SYSTEM_1\SYSTEM.DATA1'
SQL> recover database using backup controlfile until cancel;
ORA-00279 : change 26627919 generated at DATE TIMEneeded for thread 1
ORA-00289 : Suggestion E:\ORACLE\<SID>\ORAARCH\<SID>ARCHARC03020_0683715008.001
ORA-00280: change 266277189 for thread 1 is in sequence #3020
To perform a recovery with an online backup you will need all archive log files until the end of the online backup. If you have lost them you are not able to recover (or open) your database in a consistent state.
So the only suggestion we can do is:
You need the archive log files that were created during the online backup to perform an incomplete recovery ... if they are gone you can not restore your database.
Regards
Stefan
