NOARCHIVELOG mode and RMAN

Is there any way to hot backup of a tablespace without ARCHIVELOG being set to true? Or must I hot backup each individual datafile instead of the whole tablespace? It has been decided here that archiving will not be used so I'm kind of in a bind about this. Or am I doomed to cold backups only?
Thanks for any information.
Thomas Nelson

We've also got a test database in NOARCHIVELOG. We decided to
take the database down from 'open' to 'mounted' (shutdown +
startup mount) and perform a regular full RMAN backup before
opening the database again. Is this the recommended path?

Backup in NOARCHIVELOG mode using RMAN

I'm trying to do a cold backup of a database as outlined in the 'Backup and Recovery Guide':
- shutdown database using SVRMGRL
- run the backup from RMAN:
However I get the following error messages:
RMAN> run {
2> allocate channel dev1 type disk;
3> backup (database format '/oracle/backup/bp_%s_%p');}

It looks like RMAN wants to connect to the database I want to backup...
What am I doing wrong????

You've probably already figured this out, but you need to connect to the target database before doing backup/restore operations, using a command like
RMAN> connect target user/pw ...

ORA-01152 when restoring from RMAN backupset in NOARCHIVELOG mode

Hi all,
I got the error ORA-01152 when I tried restoring an Oracle 10g R1 database from an RMAN backupset into a new server. The error returned when it reached to the level of opening the database in resetlogs.
The database runs on NOARCHIVELOG mode and on Windows 2003 Server SP2 32-bit.
Following is what I did in RMAN:

Start database in NOARCHIVELOG mode

Hi,
I would like to know if there is a way to set some oracle paramete so that each time database is restarted, it comes up in NOARCHIEVELOG mode.
Regards,
Andrija

your answer is completelly wrong.
Please check description of log_archive_start parameter in documentation:
LOG_ARCHIVE_START
Parameter type
Boolean
Default value
false
Parameter class
Static
Range of values
true | false
Real Application Clusters
Multiple instances can have different values.
LOG_ARCHIVE_START is applicable only when you use the redo log in ARCHIVELOG mode. It indicates whether archiving should be automatic or manual when the instance starts up.
Values:
true
Indicates that archiving is automatic
false
Indicates that the database administrator will archive filled redo log files manually
The SQL*Plus statements ARCHIVE LOG START or ARCHIVE LOG STOP override this parameter.
In ARCHIVELOG mode, if all online redo log files fill without being archived, Oracle issues an error and suspends instance operations until the necessary archiving is performed. This delay is more likely if you use manual archiving. You can reduce its likelihood by increasing the number of online redo log files.
To use ARCHIVELOG mode while creating a database, set this parameter to true. Normally, a database is created in NOARCHIVELOG mode and then altered to ARCHIVELOG mode after creation.

Recover a deleted record in NOARCHIVELOG mode?

Hello,
I'm running 10gR2 in NOARCHIVELOG mode and we do not take backups (please, let's not get into a discussion about this!).
I need to know if there is any possible way to recover a record once it has been deleted and a COMMIT has been issued? A user inserted two records in the database that they should not have, and I need to verify there is no possible way to recover those once they have been deleted.
Thank you,
Mimi

Mimi Miami wrote:
Ok so my UNDO_RETENTION parameter is set to 900...so 15 minutes after I delete the records they should not be querable using Flashback Query any longer, right?No,
UNDO_RETENTION is low threshold value of undo retention. Meaning, Oracle will try to keep at least that time before overwritten.
However, it's not gurranteed if not enough undo tablespace available, meaning it can be overwritten before the value is up if not enough undo tablespace to serve new transaction.
On the other-hand, it will not remove the undo record until it's overwritten, meaning the record could stay there for considerable amount of time if your database is not busy and undo tablespace is big.

Not sure what's the intention to make your delete irreversible,
you could actually create table newtable as select .. from old_table where <except the two records>.
Drop the old table and rename new table.

Taking the datafile offline when the database is in NOARCHIVELOG mode

My question is when the database is in No Archive log mode i'm not able to take the datafile offline.
When i tried in my computer i have noticed fallowing.
case1:
SYS>alter database datafile 5 offline;
ERROR at line1;
ORA-01145:offline immediate disallowed unless media recovery enabled.
case 2:
SYS>alter database datafile 5 offline immediate;
ERROR at line 1;
ORA-00933:SQL command not properly ended
case3:
I have tried the command alter database datafile 6 offline drop; (in NOARCHIVELOG mode) and it is showing the same effect as alter database datafile 6 offline; ( in ARCHIVELOG mode).
*In the NOARCHIVELOG mode are we really dropping the datafile to take the datafile offline? Will you please tell me the effect of keyword drop.

The answer is that you cannot directly take a datafile offline in noarchivelog mode. You must take the tablespace offline:

Going to noarchivelog mode in 10gR2

Hi,
my database is in 10gR2 on a win XP PC in archive log mode. How can I go to non archivelog mode ?
1-Should I change Archive_log_start to false in E:\oracle\product\10.2.0\admin\bd1\pfile\init.ora ?
then
2-Shutdown immediate, startup mount, alter database noarchivelog, shutdown immediate, startup
Or may be another faster way in 10gR2 ?
Many thanks.

Archive_log_start to false Hey, this is a depricated parameter in version 10g.
Simply, mount the database and switch to noarchivelog mode and open the database.
More importantly, dont forget to have a backup.

System datafile block corruption - no backups and database in NOARCHIVELOG mode

Dear All,
Database version - oracle 11.1 Enterprise
OS - RHELinux 5.8
What are the options of recovering from physical block corruption when there are no backup available to perform block media recovery?
V$DATABASE_BLOCK_CORRUPTION reports two segments corrupted (please see attached image for details).
1 table in system datafile - sys_fba_barrierscn
1 index - (applicaiton index)
What are my options?
I know there is a possibility that the database will not restart after a shutdown due to corruption in system tablespace.
Database is in noarchivelog mode. So online backups are not possible and there aren't any full backups either.
I am thinking of below,
1. Run dbms_repair with fix_block_corruption. - Still database startup might fail?
2. Shutdown the database and take offline full backup with RMAN MAXCorrupt option.
Appreciate your suggestions and advises.
Thanks
Stefan

Thanks Sybrand,
Agree with your first two suggestions .
Also scheduled a expdp job tonight. (Only backup like thing they had was a expdp cron, but until today all the large tables were failing due to small undo_retention).
Yes. Flashback is not used. So hopefully it will not affect the a database restart i guess?
Related to dbms_repair, I was referring to - http://askdba.org/weblog/2010/08/physical-corruption-ora-1578-part-3/.
Where DBMS_REPAIR.FIX_CORRUPT_BLOCKS and DBMS_REPAIR.SKIP_CORRUPT_BLOCKS used.
Which i think will not use any redo.
Thanks

I altered it in archivelog mode.
Now I can run a backup database command from rman?What does it cost to try it and see? What would be the worst thing that could possibly happen? An error message saying you can't do that?
And please note, this forum is not a chat line. Operators are NOT standing by. Posting a new message every two minutes to give an update on the fact that the database hasn't shut down yet is not necessary and not productive.
If there are a lot of pending transactions when you issue SHUTDOWN IMMEDIATE, they will all have to be rolled back as part of the shutdown. That can take some time. And if you bypass that with SHUTDOWN ABORT, they will have to be rolled back as part of instance crash recovery on the next startup, which will also take some time. Five minutes may feel like an eternity when you are sitting there waiting for your command to complete, but is no reason to panic.

Running a physical standby database in noarchivelog mode

Primary Database: 2 node rac cluster, 11.2.0.2 GI and RDBMS
Standby Database: single instance 11.2.0.2
OS: AIX 7.1
Hello,
I'm in the process of implementing a data guard standby system. To make this system simpler to admin, I want to run the standby database in NOARCHIVELOG mode. This standby is used only as a mirror of production (to be copied to a 3rd site for separate user activity) and will never be switched to active mode. Maintaining another set of archive logs seems to be redundant to me and another point of failure, so I want to disable archiving. I wanted to ask if any of the DG experts on the forums have ever had experience with this? Does anyone know if this is recommended? I've searched the Oracle Data guard documentation online... it says that the primary obviously needs to be in archive mode, but I'm not seeing anything specific about the standby. Please let me know if anyone has experience with this.
Thanks

Hello again;
If this is the case, then I have nothing to worry about here. Does that sound right to you?Yes.
For this :
b) monthly, shutdown this system and copy it to a 3rd site to host a separate set of business activityI would consider RMAN Duplicate in which case you may avoid the shutdown.
And for this :
resync the "mirror" with productionAll you have to do if DEFER the primary to the standby, then ENABLE and Data Guard will catch up.
--- Will post a detailed example here in a moment.
Right at the first of the year they wanted to work on our Primary server room ( Power ). What I did was switchover to the Standby but I kept log_archive_dest_state_2 on the new primary set to DEFER. Then I shutdown
all the databases at the Primary site. At the end of work two days later I started the databases at the Primary site in standby mode. Switched log_archive_dest_state_2 to ENABLE. When the databases were back in SYNC
I did another switchover and it was done. I used TAF and none of the users even noticed.

Changing database to noarchivelog mode during impdp

Hi Guys,
I am using Oracle Database 10g Enterprise Edition Release 10.2.0.5.0 - 64bit Production on RHEL5.
I am in the middle on the impdp and I want my database to run on noarchivelog as it creates a lot of archivelogs.
Will it be proper if I stop the import:
e.g Import> STOP_JOB=IMMEDIATE
and shutdown the database put the database on noarchivelog mode.
then opne database and
impdp hr/hr@mydb ATTACH=myfulljob Will these work fine?
Or should I execute:
alter system archive log stop;
Please Help !!!!!!!!!!!

Vinod Dhandapani wrote:
Running the database in Noarchivelog mode means you should be ready to lose data incase there is any crash. I would recommend you to change the size of the redologs so that it will not create frequent archivelogs. Which does nothing about the space required for the archivelogs. If you are generating redo at the rate of 1gb/hour, you will consume archivelog dest space at the rate of 1gb/hour. Doesn't matter if those files are 10mb each or 100mb each.
If space is the problem then use a shell script to move the archivelog to another location (Tape)....And hopefully that shell script is invoking rman to do the work, so that in the event of recovery, rman will know that backups were taken and where they are located.

Incase you want to convert the database from archivelog to noarchivelog, follow the steps provided in the following link.
