RMAN in noarchivelog mode

Hi Experts
I need to confirm ,,, Can I use RMAN to do incremental backup level 0 and 1 in noarchivelog mode?,
if yes can you give me script as example , please note I can't take database in nomount mode.

This forum is for the Berkeley DB replication product. We cannot answer RMAN questions. I believe the forum for RMAN is:

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:

RMAN backup with NOARCHIVELOG mode

Hi,
Is it possible to EXCULDE TABLESPACE with rman using NOARCHIVELOG database ?
Thanks

Use following persistent setting:
RMAN> CONFIGURE EXCLUDE for tablespace <Tablespace Name>;
N.B. You will not be able to do this for system tablespace.

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.

How to recover a PDB in noarchivelog mode?

Backup/restore tablespaces in noarchivelog mode

In our office there is a oracle 10g box that's used for testing purposes.
It's only got 1 database, but each user has their own tablespace.
As it's not a 'live' box, archivelog and flashrecovery have been disabled by the dba probably in favour of speed.
I have a NUnit test suit that runs across a tablespace, and I am trying to restore the tablespace before each run.
In noarchivelog mode, RMAN allows me to take the tablespace offline, and create a backup - so far so good.
Later on, I am able to take the tablespace offline again, and issue a "RESTORE TABLESPACE" command.
But then I cannot bring the tablespace online without issuing a "RECOVER" command.
I have tried the NOREDO option but it still says that the file needs a media recovery before it can be brought online.
Is there a way to bring the tablespace online without applying the REDO logs ?
Or is tablespace backup/restore not possible because of noarchivelog ?
Thanks.

I tried the TTS method, and it was only marginally quicker than a data_only impdp.
I suspect this is due to the nature of a fresh nunit test database, where the metadata (huge tables structure, stored proc, etc) is often larger than the table contents itself.
In the grand scheme of things it might even end up slower, as i need to drop the tablespace including contents if i want to use TTS to load up the backed up dbf.
From the comments I'm guessing that there's no way of just updating the timestamp of the tablespace without applying the REDO logs then ?
I've tested other methods as well.
Flash recovery could only work on a table or db level, I can't take the db offline as there are other users on it with their own tablespace/schemas. (it was an old dev's box, we're reusing what we can)
impdb with the truncate and data_only flag seems to be the only viable option so far, with TTS up for consideration.

Recover datafile in noarchivelog mode

hi all
i faced problem when opening the database that there are datafile needed recovery
i'm working in noarchivelog mode
i tried to take this datafile offline but this failed
what are the exactly procedures to recover this file ?

i tried to take this datafile offline but this failed Please check your alert log file. Since you are working with noarchivelog mode. You must be having a backup. Do you ?
what are the exactly procedures to recover this file ?You have not provided enough information but here are hints;

Media failure in Noarchivelog mode

Dear all,
I am running Oracle database 10g in noarchivelog mode.
It has a media failure, a datafile has corrupted. How can i recovery it suppose i dont have the latest backup?
Thanks and regards,
Steve

Hi,
since you don't have a backup, and you have a media failure, you cannot recover.
You can set the tablespace/datafile in question offline, and work with whatever is left in the remaining datafiles. (i.e. export/import elsewhere)
if the file is just corrupted, and not lost,
you may be able to get some of the data back using oracles data unloader, but that is going to be expensive (i.e. you would need to engage oracle consulting to do it for you)
i strongly recommend you get familiar with the rman tool next time around, this is quite capable of performing backup and recovery.

Recovery in NOARCHIVELOG mode. A Sybex Study GUide quibble

Hi.
Actually, this is much more than a quibble as its a crucial point vis a vis the exam.
To perform a recovery in noarchivelog mode, we have to restore the db from the last backup.
I was under the impression that a backup of the database should NOT include the online redo logs.
But, to quote this Sybex book (p291 for Exam 032):
"To perform the database restore, you will need to copy all the data files, online redo logs, and controlfiles from the last backup and perform a full database restore" .
I understand that if we do a closed backup (as we would do if the db is in noarchivelog mode) then the redo logs are not available to be backed up and therefore are not included.
I just need this detail ironed out once and for all!
Thanks.
DA

When you restore the redo log file, you are basically defining the most recent time to which the restore can occur.
In a noarchivelog restore (of a proper clean backup), the most recent possible time is the time when the database was shut down and thus there are no redo entries to roll forward. Therefore, functionally, it really does not matter whether the redo log is restored or not. However, if the redo log file is not restored, you have two situations that must be managed: redo is much newer than the rest of the database, or redo is totally missing. Since you are in learning mode, I'll leave it to you to describe how to handle those two cases.
In an archivelog environment, restoring the redo log will severely limit the ability to restore to point-in-time as you can not move forward from the redo log's time. Therefore the recommendation is to not bother backing up the redo log file at all, so it can not be accidently restore. RMAN enforces this.
Personal 'best practice' is to make a safety copy of the redo log files before any restore. That way if an old set of redo is accidently copied or if the restore/recovery needs to be restarted, the environment can be reset to the start of the restore.

Restore in noarchivelog mode ( redo log files have been dropped )

1, A full backup taken using RMAN is available on disk.
2, The current control files were NOT damaged and do not need to be restored.
3, All data files are damaged .
4, The database is in NOARCHIVELOG mode.
I restore database :
1. RMAN> STARTUP MOUNT
2. RMAN> RESTORE DATABASE;
3. RMAN> recover database;
in this step , I got the information about needing redo log files ; but the redo log
files have been dropped , what should i do ?
else
I want to know there is the command 'recover database using backup control file'
in rman or not ?
Tks

Possibly loss of data (because information in online redo logs is lost):
recover database until cancel;
(cancel immediately)
alter database open resetlogs; (to build a new set of redo logs)
It's not necessary to use a backup controlfile here.

Standby in Noarchivelog mode

Hello,
Standby Redo Log must be archived before the redo data can be applied to the standby database. If we put our standby database in noarchivelog mode, then standby database does not generate any archive.Because of this Redo data wont apply to the standby database. Right? Is this the reason why we put standby database in archivelog mode?
Thanks

Hello;
Standby Redo Log must be archived before the redo data can be applied to the standby database.That statement is not correct.
If we put our standby database in noarchivelog mode, then standby database does not generate any archive. Because of this Redo data wont apply to the standby database. Right?That statement is not correct either. While Standby can use a process which is like generating archive, archive is really being transported from the Primary database.
Is this the reason why we put standby database in archivelog mode?Yes. If you switch modes the standby becomes the primary and needs to be in archivelog mode.
Failover
If you do a failover there are two main methods for recovery, RMAN and Flashback. You want your Standby database to be ready for use as a Primary, otherwise why have it? So you need to have it ready for anything including recovery.
I debated the archive question with somebody here last year. They claim the Standby produces Archive because such and such a process does this. I disagree. In Standby mode the database is not doing what a Primary mode database does. Those Oracle processes don't create new archive, they complete the transfer of archive from a Primary. The Sequence number was created on the Primary.
From Oracle document
"If all databases in a distributed database operate in ARCHIVELOG mode, you can perform coordinated distributed database recovery. However, if any database in a distributed database is in NOARCHIVELOG mode, recovery of a global distributed database (to make all databases consistent) is limited by the last full backup of any database operating in NOARCHIVELOG mode."
If you search this document
Data Guard Concepts and Administration 11g Release 2 (11.2) E10700-02
For "ARCHIVELOG" you get several hits.
If you search for "NOARCHIVELOG" you get none.
I suppose in theory you could run a Standby in "NOARCHIVELOG" but you gain nothing. If you ever have a switchover or failover you need to fix this ASAP. I see no reason to add that item to my checklist. It just an extra step and in the event of a failover one I could be very unhappy about.
