Coldbackup with Archivelog mode
I am running database in archive mode and I also take a coldbackup once a week. I was wondering if I ever need to recover this database from backup, how am I going to apply archive logs created after cold backup taken. since restoring database from cold backup will be in consistent state. Do i need to restore backup controlfile and do incomplete recovery?
it's a slight misunderstanding.
You can recover the cold backup and switch it on. -therefore you will have a database from the point of the cold backup.
if you want to use the archivelogs to restore then that's a little more involved

OLAP in 10G with ARCHIVELOG mode
Can we place 10G database in ARCHIVELOG mode with OLAP? Currently we are at 9204 and our database is running in NOARCHIVELOG mode. I am new here and I was told that there is some issue with the OLAP that prevents placing the database in ARCHIVELOG mode. Is it true? If it is true then has it been fixed in 10G as we want to take advantage of FLASHBACK query option of 10G and that will require the database to be in ARCHIVE mode?
Thanksit's a slight misunderstanding.

Performance deteriorates with archivelog mode
hi,
i want to implement an incremental backup procedure for a 9i database, but the database is in noarchivelog mode.
switching to archivelog mode results in a considerable loss of performance.
is there anything that can be done to either make incremental backups in it's current state, or speed up performance once it is in archivelog mode?
thanks

Rman backup with no archivelog mode
Hi Friend,
I did this backup many times before, to backup a test db which is not in archivelog mode.
My procedure are the following:
$ rman target /
rman> run {
shutdown immediate;
startup mount;
backup format '/u02/RMAN/%d_LVL0_%T_%u_s%s_p%p' database;
delete obsolete;
But strange I got now error:
ORA-19602: cannot backup or copy active file in NOARCHIVELOG mode
Thanks a lotHi,
Paste the snap shot of what you actually doing and what error messages are coming. That will help to analyze the problem.
This basically happens when your shutdown is not normal or clean.
One way is to again startup the database and then issue shutdown Normal.

Problem running oracle 9i database in archivelog mode - database freezes
Greetings,
I recently needed to change a (test) database to archivelog mode to make online back-ups of this database. This posed no real problem although I seem to be unable to set the database to automatic archiving eventhough I edited the init.ora file (translation of the "archive log list" output between square brackets):
SQL> archive log list
Databaselogmodus Archiveermodus [Databaselogmode: Archivemode]
Automatisch archiveren Gedeactiveerd [Automatic archiving: Deactivated]
Archiveerbestemming O:\oracle\ora92\RDBMS [Archivedestionation: O:\oracle\ora92\RDBMS]
Oudste on-line logreeks 12306
Volgende logreeks voor archivering 12306
Huidige logreeks 12308
I added this to my init.ora file:
# Archvie Log Destinations
log_archive_start=TRUE
log_archive_dest_1=%ORACLE_HOME%\database\archive
log_archive_format="%%ORACLE_SID%%t_%s.arc"
However, this is not the real problem (maybe it has something to do with it, which is why I mention it aswell), the real problem is that my database freezes when the archive log file is "full". When the archive file reaches ~102.400Kb it just freezes up and I need to restart the database.
The following error is written to the alert_sid.log file:
Thu Apr 17 09:19:55 2008
Thread 1 cannot allocate new log, sequence 12309
All online logs needed archiving
Current log# 2 seq# 12308 mem# 0: O:\ORACLE\ORADATA\O\REDO02.LOG
The problem seems to be that the oracle service can't start a new logfile when the previous one is full. Does anybody know how I could fix this?
Thanks in advance,
BramHello Maran, thanks for your quick response.
I added the output of archivelog list in the original post, but it's in dutch so here's the (loose) translation of the output:
SQL> archive log list
Databaselog mode Archive mode
Automatic archiving Deactivated
Archive destionation O:\oracle\ora92\RDBMS
Oldest on-line logsequence 12307
Next logsequence for archiving 12307
Current logsequence 12309
Maybe something that can help with the troubleshooting:
The archivelog file is written to O:\oracle\ora92\RDBMS but only AFTER the reboot, I've checked SYSTEM rights to the folder and it has full control.
Babu, thanks aswell for your quick response.
The location exists and space is available but the database doesn't seem to load (that part of) the ora.init file because the output of archive log list still refers to %ORACLE_HOME%\rdbms instead of %ORACLE_HOME%\database\archive.
I've now executed alter system archive log all; and am executing the import where the database usually freezes to see if it still happens. So far I already had this written to the alert_sid.log file after executing the command:
Completed: alter database open
Thu Apr 17 10:00:11 2008

And new log files were written to the directory (O:\oracle\ora92\RDBMS) and this time I didn't have to reboot for it to happen. Both were 100mb files without the database actually doing all that much though.

Hi
All,
I have oracle 9.2.0.6 at my workplace.right now my database running in ARCHIVELOG MODE. I want to set it to NOARCHIVELOG MODE.
can I do on the fly? in other way, Do I need to shutdown and restart database?
Any help will be appreciated.
Thanks,
VishalHi,
Issue the following commands to put a database into NOARCHVELOG mode:
1) Take Back up of Present SPfile by creating pfile
create pfile from present spfile.
2) Shutdown the database by SUTDOWN IMMEDIATE.
3) Take Cold backup of the database.
4) Change the parameter in the pfile.
log_archive_start = FALSE
#log_archive_dest_1 = 'LOCATION='Your location'
log_archive_dest_state_1 = DISABLE
#log_archive_format = %d_%t_%s.arc
5) And make a spfile from the modified pfile in default location .
6) Start the database with spfile.
SQL> CONNECT sys AS SYSDBA
SQL> STARTUP MOUNT ;
SQL> ALTER DATABASE ARCHIVELOG;
SQL> ARCHIVE LOG START;
SQL> ALTER DATABASE OPEN;
NOTE 1: Remember to take a baseline database backup right after disabling archivelog mode. Without it one would not be able to recover.

Problem in Converting Database into Archivelog mode (Oracle 10G)
Hi Team,
I come across a strange problem in the ORACLE 10G Server.

The same thing is working in the Oracle 9i but not in the Oracle 10G.
Can Anybody plz help me in this?

.export ORACLE_SID=<SID>
rman target /cmdfile="C:\ORACLE~2\BACKUP\backup.ora"
it will connect to the default SID, there's no such thing as a default SID, what do you mean?
But what if there are more that one SID available & I
want to connect to SID other than the default SID.just specify the desired SID prior starting rman.
more over the same string is working with 9i but not
with 10G.maybe due to a bug?
to summarize, you have two options it you would like to start up the instance:
either you specify the SID prior starting rman and use os authentication
or
you register the instance statically and use oracle authentication.

Database crashes when placed in Archivelog mode
My production database continues to crash when I place it in Archivelog mode. This happen especially during the period most of the heavy jobs is running. On the other hand, I created a clone of this very same database on another server in Archivelog mode and it is running great. It’s also honest to say the jobs that run on the production are not running in the clone.
Any advice will be appreciated.

Why we need oracle database reboot to put database in archivelog mode?
I know how to enable archivelog mode, but what is the reason that to enable archive log we need database restart. which process forces to do that.

Thanks a lot EdStevens for ur prompt response...I need something that satisfies my managers query.
If the question has originated with the PHB, then my flippant answer is even more relevant ...
PHB's are incapable of understanding the technical details, so I prefer to give them the 'executive summary':
"Because that's the way Oracle is written. We can argue over the technical merits of such a requirement 'till the cows come home. But at the end of the day, we have to shut down the database because the 'alter database archivelog' command will only succeed when the database is in mount (not open) mode. Now, let's work out how we can achieve our objective of putting the database in archivelog mode with minimal and appropriately scheduled down time."
As for the actual down time, it's about as minimal as you can get. How long does it take your database to complete a shutdown once the command is given? How long does it take you to type "startup mount"? How long does it take you to type "alter database archivelog"? to type "alter database open;"? For the database to complete the 'open' process? You could even script it so as to eliminate the keyboard typing time. -
ARCHIVELOG mode needless for offline (cold) backups ?
When I read some tutorials or comments about backup with rman or expdb I saw often the recommendation to put database in ARCHIVELOG mode.
But this is from my point of view useless when I do such a backups in offline mode.
I want to backup the current state of the database - full stop.
Redo logs from ARCHIVELOG are not necessary. Only if I want to go further back from the current state back to the past they are of use.
Am I right?
PeterData pump does not require or use archivelog mode for importing, or exporting.
The archivelog mode is required, however, for RMAN backups, except for full database copy which it copies while the database is shutdown.
The Data Pump utility uses a parameter called FLASHBACK_SCN (and FLASHBACK_TIME) which reads the undo data, but not to be confused with archivelogs.
NOTE that if you set archivelog mode on, you may want to either turn off archivelog mode when importing, or set the tabelspaces to nologging (then back to logging when done). Otherwise, it may cause enough archive logs during import to fill up your file system.

Restore using incremental backup with noarchivelog mode
Hello experts,
We are running SAP on Oracle databse(IN NOARCHIVELOG MODE) for which we are having full offline backup on every sunday and post which incremental backups on rest of the days. We have scenario to do restore db to the state till last friday's incremental backup.
Please let us know the procedure for restoring till that point. If possible using brtools utility(which is SAP specific).
Thank You

Recovering a NOARCHIVELOG Database with Incremental Backups
Restoring a database running in NOARCHIVELOG mode is similar to restoring a database in ARCHIVELOG mode. The main differences are:
Only consistent backups can be used in restoring a database in NOARCHIVELOG mode.
Media recovery is not possible because no archived redo logs exist.
You can perform limited recovery of changes to a database running in NOARCHIVELOG mode by applying incremental backups. The incremental backups must be consistent, like all backups of a database run in NOARCHIVELOG mode, so you cannot make backups of the database when it is open.
When you are recovering a NOARCHIVELOG database, specify the NOREDO option on the RECOVER command to indicate that RMAN should not attempt to apply archived redo logs. Otherwise, RMAN returns an error.
To recover a NOARCHIVELOG database with incremental backups:
After connecting to the target database and the recovery catalog, place the database in a mounted state:
STARTUP FORCE MOUNT
Restore and recover the database.
For example, you can perform incomplete recovery with the following commands:
RESTORE DATABASE
FROM TAG "consistent_whole_backup";
RECOVER DATABASE NOREDO;
Open the database with the RESETLOGS option.
For example, enter the following command:
ALTER DATABASE OPEN RESETLOGS; -
Recover datafile in no archivelog mode
Hi, i have always done media recovery using RMAN and this works nicely.
However im doing some testing on a database that does not use RMAN and is not in archivelog mode and im confused.(11.2 - aix)
My testing is as follows;
With the database shutdown cleanly i have taken a copy of dbf file. I then open the database and delete the dbf file.
(to slightly digress how can i still view and update the table from this datafile when the dbf file is dropped?)
In scenario 1 i shutdown the database after dropping the file. I then put the dbf file back and try and startup the database.
I thought that as i have a complete consistent backup i would be able to open the database normally without recovery, but this produced an error saying the file needed media recovery so i recovered the datafile and put online and the the db opened normally.
In scenario 2 i again took a clean backup and removed the dbf file. I then opened my database and switched redo logs 3 times ( i have 3 redo logs). After the 3rd switch the database crashed (which makes sense).
I have tried opening it normally again butagain it says the file needs media recovery. i then tried to recover the file but now i the following error:
ORA-00279: change 6667823 generated at 12/17/2013 11:35:20 needed for thread 1

In all *nix systems, the file is still there and open by any processes that had it open when you issued the 'rm' command. It is not really deleted until all processes that have it open have terminated.
In scenario 1 i shutdown the database after dropping the file. I then put the dbf file back and try and startup the database.
I thought that as i have a complete consistent backup i would be able to open the database normally without recovery, but this produced an error saying the file needed media recovery so i recovered the datafile and put online and the the db opened normally.
The backup may have been consistent, but if you restored only that one file, it was several SCN's behind the other files that continued to be updated after you took the consistent backup. "Consistent" means not only consistent interally to the individual file, but consistent with all other data files, plus the control files, plus the redologs.
In scenario 2 i again took a clean backup and removed the dbf file. I then opened my database and switched redo logs 3 times ( i have 3 redo logs). After the 3rd switch the database crashed (which makes sense).

You said you are not in archivelog mode. So where did this reference to an archivelog come from? -
Dear Sirs,
Actually I've a non archivelog mode RDBMS, but I wan't to make a
hot backup. Could I make a hot backup after I turn the
ARCHIVELOG mode ON, then turn it off again after Back - Up ?
And how do I make the hot backup ?
Thank you for the attention and help.
Regards,
TonnyYou could turn archivelog mode on, do the backup, and then turn
archivelog mode off. This really defeats the purpose of hot
backups though. You would have to know the SCN, archivelog
file, or time to do a point-in-time recovery manually, or if you
are using RMAN knowing the time will help. I think RMAN will
recover until the last archivelog if you don't specify a time or
SCN. Keep in mind that you will lose all the changes since the
last backup if you turn archivelog mode off after the backup and
your database crashes inbetween the next scheduled backup. If
you are going through the trouble for turning archivelog mode on
and then off I would perform a cold backup. You have to
shutdown the database with normal or immediate, mount the
database, turn archvelog mode on/off and then open the
database. So why not just do a cold backup? -
Archivelog Mode / init.ora file
Hi,
Maybe someone can help me out. I am presently trying to set up a dev server that has 3 or 4 databases on it. The first database is installed by the Oracle installation kit. The 2nd one that I am now trying to configure is giving me the following error: Ora-01126: database must be mounted EXCLUSIVE and not open for this operation. I am also setting it up for archiving.
When I do a SELECT * from V$database; the answer comes back that it is in noarchivelog mode. I even edited the init.ora file in both the pfile folder and the ora81/database folder and yet the answer is still the same. I even rebooted it with the same results. I understand that the database is in exclusive mode by default. Does this have anything to do with Parrelizm (spelling). I tried altering the database to archivelog mode but with no results.
Any ideas? Im at a loss.
Thanks for your time.
AlHi Al,
try to startup the db with startup mount or startup read only and try
the alter command again.
Normally it should work then!

Is there any way that without shuting down the database i can switch to archivelog mode.
Please comments...
Shatrughanif we shutdown immediate one's database..do
it's listener terminated too???The database registration with the listener yes, the listener itself no. That is, if you execute a command like "lsnrctl stat" you won't see the database anymore, but the listener is still active. Example :
[ora102 ~ db102]$ lsnrctl stat
