Regarding Online Redo log backup
Dear all,
I am running "Whole database online + Redo log backup" in production server which running successfully with return code 0000.
Is this backup takes online redo log file also?????? because in backup log i didn't see any directory like .../../orilog A, .../../orilog B etc which contains online redo log file.
Without this online redo log backup i don't thing we can do point to point recovery.
I am beginner for oracle so please clear this doubt.
thanks,

You have offline redo log files in 'oraarch' --> this means that 'online redo logs' are getting backed up into 'oraarch'.
sql > archive log list
http://www.adp-gmbh.ch/ora/sqlplus/archive_log.html
Above command tells whether the logging is ON or not. If it is ON, then online logs will be generated w.r.t. every sap work and as soon as the online logs gets filled up - it gets backed up into 'oraarch' - to accommodate more logging with time.

Whole database online + redo log backup
Hello all,
we are running SAP on a Oracle Database and doing a daily backup.
In the DBA Planing Calendar, we do have the action
Whole database online + redo log backup
What exactly does that mean?
Thanks,
AnneThis backup will save the CONTENT of the database only, not the database software itself.
To get a full consistent backup you need to backup more things if you want to have everything - depending on the operating system:
On Unix you will need to backup the software directory (/oracle*, oraInventory, oratab (depending on the location)) etc.
On Windows you will need to backup <letter>:\oracle, the registry keys and more things.
However, in case of a recovery you can also install the software after an OS installation and then restore it from tape.

Problem with Whole Database Online+Redo log Backup
Dear Marcus Sir,

AhsanHi,
since you are getting a read error, it might as well be, that your datafile is defective.
Try the same dd-command to /dev/null, to see if it is possible to read the entire file.
First make sure that your null-device is existing, otherwise you might face a root-fs full problem.
dd obs=1024K bs=1024K if=/oracle/ANP/sapdata2/sr3_9/sr3.data9 of=/dev/null
or try a dbverify on it, which would also read the entire file and do a checksum test.
brbackup -c -u / -m /oracle/ANP/sapdata2/sr3_9/sr3.data9 -t online -w only_dbv
Good luck

Note: presently i have taken backup on single tape.

Full Online + REDO Log backup failing
Hi Experts,
We have a failing backup when running a 'Full Online + REDO Logs' scheduled via DB13 (ERP6/Windows 2008/Oracle 10.2.0.4)
Whilst it is successful in backing up the datafiles and the REDO logs to the remote destination, it fails to catalog the backup, displaying the following message:
ORA-19625: error identifying file
Backup_Destination\BEFSDJTA\SR3.DATA10
ORA-27041: unable to open file
OSD-04002: unable to open file
O/S-Error: (OS 5) Access is denied.
RMAN>
Recovery Manager complete.
BR0280I BRBACKUP time stamp: 2011-04-21 07.20.49
BR0279E Return code from 'F:\oracle\SID\102\BIN\rman nocatalog': 1
BR0536E RMAN call for database instance EQ1 failed
BR0280I BRBACKUP time stamp: 2011-04-21 07.20.49
BR0532E Cataloging backups of all database files failed
From what I understand, RMAN runs under the OracleService<SID> service, which calls the oracle.exe process, which is owned by the local user SYSTEM. This accounts for the access denied problem when accessing the remote destination using the RMAN utility.
As a test, I'm aware that if I change the ownership of oracle.exe to a non-local, domain user (<SID>adm), I can run RMAN commands without the permission denied error occuring. (performed this on a Sandbox)
The problem when I use this <SID>adm account as the oracle.exe owner, is that the SAP application Work Processes won't connect to oracle.
My questions are:
Is it a valid workaround to change the process owner of oracle.exe to something other than the local SYSTEM user?
If so, what are the criteria that need to be met for the new domain user to ensure that the SAP application is stable?
Does anyone know of an alternative workaround?
Thanks,
Chris WHi Markus,
Thanks for the response.
I've managed to get the SAP application to run with Oracle using the <SID>adm account as the OracleService<SID> owner.
The original problem with the SAP work processes in connecting with the Oracle database was due to the Oracle listener services also being owned by local user SYSTEM.
I changed the listener services ownership to <SID>adm (as well as the OracleService<SID>) and this allowed the connection between the SAP work processes and Oracle.
Also, I gave the domain <SID>adm account local administrator rights (same as SYSTEM) and have seen no problems since the switch.
I can also access a remote host using the RMAN utility - problem appears to be solved.

Whole Database Online + redo log backup: How Long?
Hi gurus,
There's something I want to ask about online backup with redo log.
If i'm correct, redo log file is created everytime there's operation that change datafile right?
If i schedule this type of backup everyday, it means it will backup all datafiles, along with redo log file when transaction take places, at my pre-defined hours, right?
Then here's what i'm confused about. When will this backup process finished? Is it when all the datafiles have been backed up? Then how about the redo log files? If there are users that keep making transaction (therefore make change to datafiles), new redo log files will be created on disk, and that will prevent the backup process to finish. Then when will this cycle come to an end?
Please confirm if my grasp about oracle online backup is correct or not, and provide explanation to satisfy my curiousity.
Thanks gurus,

i am feeling honored
> Keep in mind that the only thing where a DBA cannot make mistakes is restore/recovery and this depends on your backups
In general i would say you are right, but i have seen already one case where this statement is not true.
Some time ago i got a call from a colleague where his database crashed, the online redolog files were corrupted and the recovery was not working.
If you don't look really close at this point you are in trouble and can not continue the recovery. Let explain this on a example.
This demonstration is done on an oracle 10.2.0.4, but it work on every other version too.
Let's simulate a crash
SQL> shutdown abort;
Corrupt/delete a specifc redolog file
SQL> startup
ORA-00313: open failed for members of log group 3 of thread 1
ORA-00312: online log 3 thread 1: '/oracle/TST/oradata/redolog/redo03.log'
ORA-27037: unable to obtain file status
Ok - so far so good, lets check the groups and files
SQL> select GROUP#, STATUS, MEMBER from v$logfile where TYPE = 'ONLINE';
GROUP# STATUS MEMBER
1 /oracle/TST/oradata/redolog/redo01.log
2 /oracle/TST/oradata/redolog/redo02.log
3 /oracle/TST/oradata/redolog/redo03.log
SQL> select * from v$log;
GROUP# THREAD# SEQUENCE# BYTES MEMBERS ARC STATUS FIRST_CHANGE# FIRST_TIM
1 1 95 52428800 1 NO CURRENT 5117817 06-JAN-09
3 1 94 52428800 1 YES ACTIVE 5117814 06-JAN-09
2 1 93 52428800 1 YES ACTIVE 5112855 15-DEC-08
What's the situation?
The online redolog file of group 3 is lost/corrupted and this group is needed to perform a complete recovery (see status ACTIVE).
But you are lucky, because of this group 3 is already archived - so you can perform a complete recovery.
Now let's perform a complete recovery but with UNTIL clause (because we need to jump between the online and archived redologfiles)
SQL> recover database until cancel;
ORA-00279: change 5116194 generated at 01/06/2009 21:06:48 needed for thread 1
ORA-00289: suggestion : /oracle/TST/oraarch/TST_1_93_6b8c0516_666969185.arc

Specify log: {<RET>=suggested | filename | AUTO | CANCEL}
/oracle/TST/oradata/redolog/redo01.log
Log applied.
Media recovery complete.
Now execute an OPEN NORESETLOGS accidentally (maybe the dba think it is not necessary because of the complete recovery) and try an OPEN RESETLOGS after:
SQL> alter database open noresetlogs;
alter database open noresetlogs
ERROR at line 1:
ORA-00313: open failed for members of log group 3 of thread 1
ORA-00312: online log 3 thread 1: '/oracle/TST/oradata/redolog/redo03.log'
ORA-27037: unable to obtain file status
SQL> alter database open resetlogs;
alter database open resetlogs
ERROR at line 1:
ORA-01139: RESETLOGS option only valid after an incomplete database recovery
So now you are lost.. you can't execute an UNTIL CANCEL anymore which would be needed to perform a successful OPEN RESETLOGS.
In this special case you can do mistakes and you have to restore the whole database and perform the same recovery again and end with OPEN RESETLOGS.
Just for information

Backup Not Starting for 'Whole database offline + redo log backup' @ DB13
Hi Experts,
I am not able to perform 'Whole database offline + redo log backup' by DB13.
I have recently configured my 'init<SID>.sap' to take 'Whole database online + redo log backup' and its working perfectly fine.
I tried taking test backup for 'Whole database offline + redo log backup' but it didn't even started.
Thus I created another profile with name init<SID>back.sap and changed the Parameter
from 'backup_type = online' to 'backup_type = offline' and also tried by 'backup_type = offline_force'
rest all parameters being same as the profile init<SID>.sap
Kindly Suggest as I need to take set the backup Strategy as Mon-Fri -> 'Whole database offline + redo log backup' and Sat -> 'Whole database offline + redo log backup'
One more Query : While taking the redo log backup by DB13 why is it that some times it only saves the Files and some time it
saves and delete the files from the '/oracle/<SID>/oraarch' location. Please throw some light over this matter also.
Thanks,

The file structure online redo log, archived redo log and standby redo log
I have read some Oracle documentation for file structure and settings in Data Guard environment. But I still have some doubts. What is the best file structure or settings in Oracle 10.2.0.4 on UNIX for a data guard environment with 4 primary databases and 4 physical standby databases. Based on Oracle documents, there are 3 redo logs. They are: online redo logs, archived redo logs and standby redo logs. The basic settings are:
1. Online redo logs --- This redo log must be on Primary database and logical standby database. But it is not necessary to be on physical standby database because physical standby is not open. It doesn't generate redo log. However, if don't set up online redo log on physical standby, when primary failover and switch standby as primary. How can standby perform without online redo logs? In my standby databases, online redo logs have been set up.
2. Archived redo logs --- It is obviously that primary database, logical and physical standby database all need to have this log file being set up. Primary use it to archive log files and ship to standby. Standby use it to receive data from archived log and apply to database.
3. Standby redo logs --- In the document, it says A standby redo log is similar to an online redo log, except that a standby redo log is used to store redo data received from another database. A standby redo log is required if you want to implement: The maximum protection and maximum availability levels of data protection and Real-time apply as well as Cascaded destinations. So it seems that this standby redo log only should be set up on standby database, not on primary database. Am my understanding correct? Because I review current redo log settings on my environment, I have found that Standby redo log directory and files have been set up on both primary and standby databases. I would like to get more information and education from experts. What is the best setting or structure on primary and standby database?FZheng:
Thanks for your input. It is clear that we need 3 type of redo logs on both databases. You answer my question.
But I have another one. In oracle ducument, it says If you have configured a standby redo log on one or more standby databases in the configuration, ensure the size of the current standby redo log file on each standby database exactly matches the size of the current online redo log file on the primary database. It says: At log switch time, if there are no available standby redo log files that match the size of the new current online redo log file on the primary database. The primary database will shut down
My current one data gurard envirnment setting is: On primary DB, online redo log group size is 512M and standby redo log group size is 500M. On the standby DB, online redo log group size is 500M and standby redo log group size is 750M.
This was setup by someone I don't know. Is this setting OK? or I should change Standby Redo Log on standby DB to 512M to exactly meatch with redo log size on primary?

Physical Standby Online Redo log files,
Hi,
I'm trying to create a physical standby database (10.2.0.3). I'm a little confused about the requirement for online redo logs on the standby.
in my standby alert log I get the following when I issue:
SQL> alter database recover managed standby database disconnect from session
"ORA-00313: open failed for members of log group 1 of thread 1
ORA-00312: online log 1 thread 1: '/appl/oradata/prod/prod_1_redo_01_02.log'
ORA-27037: unable to obtain file status
SVR4 Error: 2: No such file or directory
Additional information: 3"
/appl/oradata/prod/prod_1_redo_01_02.log is the path to the location of the online redo logs on the production system. This file does not exist on the standby filesystem so the error is correct.
I assume that it gets this information from the standby control file I created on the production system and copied over to the standby.
Do I need to copy the online redo logs from the primary over to the standby site or do I need to create online redo logs on the standby?
Does the standby need to have redo log files?
I'm not talking about 'standby log files' of the type created using 'alter database add standby log file'. I've not got that far yet.
I just need to establish if a physical standby requires online redo log files?
Thanks in advance,
user234564I wanted to update this thread since I've been dealing with the exact same errors. The basic question is: "does a physical standby need the online redo logs?"
Answer: Not really, until one wants to switchover or failover (and become a primary database). Furthermore, whenever the MRP process is started, Oracle prepares for a possible switchover/failover by "clearing" the online redo logs (MetaLink note# 352879.1). It is not a big deal, since Oracle will build the actual redo files when the "alter database open resetlogs" is accomplished during a "role transition."
In our situation, we have decided to use our standby for nightly exports. We stop MRP, open the database read-only, then restart MRP. We built these standby DBs with RMAN. The RMAN duplicate process will not build the online redo log files until the database is opened for read/write (with resetlogs). However, we haven't had a need for read/write (i.e. a switchover).
Thus, every morning we have been getting the same errors that "user234564" posted above. At first the errors seemed scary, then we realized they were just a nusiance. In order to clean things up, all I did was just "cp" our stanby redo logs (SRL) into our online redo directories ensuring the names matched what was in v$logfile. When I restarted MRP, the alert log clearly showed Oracle clearing these "newly found" online redo logs. -
Behaviuor in reading logs from DB13 - redo log backup for DB
Hi all,
I have a question ,
We have scheduled redo log backup using HP DP Tool.
When I am reading a backup log from DB13 , I am facing the weird behavior.
copy, delete, save
0000
aeomzyok.cds
copy, delete, save
0001
aeomzyoh.cds
Where ever the RC is 000 I am able to read the log files available at OS level . But not able to read the log for other RC.
Please help me to understand this
Thanks,
GnanaHi Gnana.
Use the latest BR*Tools as there were problems with permission issues while creating logfiles. In the latest BR*Tools version, the different logfiles are created with predefined permission levels that suits to SAP needs.
Also it worth to check if the BR*Tools executables hav the correct ownership.

Cold backup with online redo logs
I am working on 10G in AIX for a single instance
It is just a general db backup & restore question, but I have something confused.
I am going to perform a cold backup with my ARCHIVELOG database.
No wonder why I perform a cold backup because it is a testing database which can suffer from data lost and down time during backup.
I read some guides. They all mentioned to backup all the datafiles and control files.
During the restoration, I have to copy all the backed up datafiles and control files to the default location.
Then Startup mount;
The last step before open the database is recover database until cancel;
For the acknowledgement, I have to do the command of recover database, because the online redo logs were not backed up, thus we have to recover it in order to reset the redo logs.
For my question,Would I be able to skip the command of recover database, then directly startup the database if I have backed up the online redo logs and copy the default location during the restoration?
However, I read many documents which mention that it is not suggested to backup the online redo logs. Is it just the case which ONLY applied in hot backup? Do you all think that for my case, cold backup for online redo logs is recommended?
Thanks alljgarry wrote:
Edit: And never forget, those test databases are some developers production.Absolutely true according to my experience. Loosing the work of a payed developer is just as bad as loosing the work of a production system and may even be worse because it may not be possible to re-enter missing data into the system.
I think a cold backup is only suitable on special occasions, for instance, to relocate/copy the database to a different storage media, or if the database doesn't change or if loosing changes is absolutely irrelevant. Otherwise, put the database into archivelog mode and do a hot backup. After that you will also have alternative options which can make the restore and recovery of the database very easy and efficient, like flashback database, etc. but it will take substantial additional disk space. -
Can we use online redo log to recover lost datafile in NOARCHIVE mode?
I am working on OCA exam and confued about these 2 sample questions. (similar questions with totally different answer)
Please give me hint about the different between these 2 questions.
** If the database is in NOARCHIVELOG mode, and one of the datafile for tablespace USERS is lost, what kind of recovery is possible? (answer: B)
A. All transactions except those in the USERS tablespace are recoverable up to the loss of the datafile.
B. Recovery is possible only up to the point in time of the last full database backup.
C. The USERS tablespace is recoverable from the online redo log file as long as none of the redo log files have been reused since the last backup.
D. Tablespace point in time recovery is available as long as a full backup of the USERS tablespace exists.
** The database of your company is running in the NOARCHIVELOG mode. You perform a complete backup of the database every night. On Monday morning, you lose the USER1.dbf file belonging to the USERS tablespace. Your database has four redo log groups, and there have been two log switches since Sunday night's backup.
Which is true (answer: B)
A. The database cannot be recovered.
B. The database can be recovered up to the last commit.
C. The database can be recovered only up to the last completed backup.
D. The database can be recovered by performing an incomplete recovery.
E. The database can be recovered by restoring only the USER!.dbf datafile from the most recent backup.I think Gaurav is correct, you can recover to the last commit even in NOARCHIVELOG, as long as all the changes in the redo logs have not been overwritten. So answer should be B for question 2.
Here is my test:

Below quoted sentence is from Oracle documentation
"Online redo logs, unlike archived logs, should never be backed up. The chief danger
associated by having backups of online redo logs is that you may accidentally restore
those backups without meaning to, and corrupt your database"
Can any one explain , how the database will be corrupted if we backup online redo logs. I am having a hard time to understand this quote
thanks for your help
shajanRedo log file contents is very dynamic. It changes minute after minute, so a backup is useless if you try to do it online. (In fact there is no command to perform such backup).
Let's suppose you shutdown (normal, immediate or transactional) The contents of the redo log files become useless as the checkpoint process has already taken place, so it is enough to have a copy of all of the consistent datafiles to have the last applied transaccion.
In a recovery scenario with archivelog it is important to keep all of the requiered archivelog files plus all of the online redo log files.
In case of a missing logfile it is useless to have a backup of it. If you ever had one, and you tried to restore it, an error would arise, warning you that the contents of the logfile is inconsistent with the expected scn. The only way you can succeed is to have them multiplexed and have them on different paths, just to reduce to probability of loosing all of the members of a group.
rman does not perform backup of redo log files. Classical theory of backup/recovery states that during a hot backup it must be backed up the archive log files, not the redo log files. -
