Oracle recovery in noarchivelog mode

Hello,
SAP Release : ECC6
Oracle 10G
Solaris 10g
Our SAP system is in noarchivelog mode (formation environnement, with frequent client copies).
We frequently perform an offline backup.
The solaris server that is hosting our Sap system, has been brutally shutdown this morning,
due to a network issue.
Afterwards, we had to restart the sap system.
A fisrt error occured ; inconsistency between the control files ...
ORA-00205: error in identifying control file, check alert log for more info
In alert log :
ORA-00202: control file: '/oracle/ZMA/origlogA/cntrl/cntlrZMA.dbf'
ORA-27037: unable to obtain file status
We regenerated a new control file and replaced it.
The error was solved.
Then a second error occured :
SQL> startup

The redo log #76005 is no more available; I tried to apply the online redo logs, but it didn't help.
We had to restore the whole database from the offline backup.
1/ I still have problems understanding why Oracle is asking for a recovery, when we tried to reopen the database ? The database was consistent this morning, how is it that the file '/oracle/ZMA/sapdata1/system_1/system.data1' became inconsistent ?
2/ In sap note 863417 "If the database operates in NOARCHIVELOG mode, the database can ONLY be completely recovered from instance failure but not from media failure. "
What is exactly the difference between media failure and instance failure ?
Does a network problem and then a reboot of the host is considered a media failure ?
Best Regards.
thank you for your help .

> 1/ I still have problems understanding why Oracle is asking for a recovery, when we tried to reopen the database ? The database was consistent this morning, how is it that the file '/oracle/ZMA/sapdata1/system_1/system.data1' became inconsistent ?
Because the database was not shut down cleanly. An open database is by definition "inconsistent" without the proper logfiles.
> 2/ In sap note 863417 "If the database operates in NOARCHIVELOG mode, the database can ONLY be completely recovered from instance failure but not from media failure. "
> What is exactly the difference between media failure and instance failure ?
Media = File/Raw-Device. If you database is crashing due to a software error it can be recovered, if a file is corrupt it can't be (since you have no redo logs).
> Does a network problem and then a reboot of the host is considered a media failure ?
A corrupt control file (e. g.) is a media failure.

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.

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.

Database Recovery in NOARCHIVELOG Mode

Hi All,
I was trying to 'startup' my database & encountered the following error in the alert.log
ORA-01242: data file suffered media failure: database in NOARCHIVELOG mode
ORA-01122: database file 469 failed verification check
ORA-01110: data file 469: '/ora/ctcm_uat02/CMOLP1/undo/CMOLP1_undots_30.dbf'
ORA-01209: data file is from before the last RESETLOGS
I then looked up on the internet and since the error was related to the UNDO TABLESPACE, i did the following:
sql>startup mount
sql>alter database datafile '/ora/ctcm_uat02/CMOLP1/undo/CMOLP1_undots_30.dbf' offline drop;
sql>alter database open
Thereafter the database kept on erroring on all the datafiles belonging to the undo tablespaces and i dropped all the datafiles belonging to the undo tablespace using the above command. (alter database datafile ....offline drop).
Next, i tried to open the database and got the following error from the alert log:

Hi ERROR,
I think i figured out the hidden parameter that you were referring to.
(1) I set the allowresetlogs_corruption=TRUE and commented undo_management. Then opened the database using--> alter database open resetlogs;
But still was not able to start the database. The alert log entries are as below:

Recovery in noarchivelog mode

Scenario :
- Database is in noarchivelog mode.
- There are two redo logs for a database.
- A closed database backup was taken at log sequence 144.
- While the database was at log sequence 145, data file 2 was lost.
how can i recover the database till log sequence 145.
Kindly help me in this regard.

Hi,
If Current log sequence 145
& If log sequence 144 not overwritten the time cold backup (all datafiles+controlfile+redo logfile ) was taken, then use following steps:
1> shutdown ( if database is open)
2> restore only corrupted datafile
3> startup mount
4>recover database
5> alter database open

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
Regards,
Venkateshwar

If you do not want to read the whole doc This is the snippet for 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;

Anyone running Portal with NOARCHIVELOG mode in the Oracle DB?

Although we have several high-volume SQL Server customers running their DB in simple recovery mode (no transaction logging) with success, I am trying to determine if anyone is doing the equivalent with Oracle DB.
Even if you aren't using NOARCHIVELOG mode, please let me know your thoughts on performance, especially since the perception exists that the Portal is less performant on Oracle DB than on SQL Server. If that perception has any basis in reality, there should be an even greater potential for performance gain using Oracle DB, through intelligent tuning.
The cons of NOARCHIVELOG were pointed out to me by an excellent DBA:
1. Lose the ability to do hot online physically backup, (both RMAN and Manual)
2. Lose the ability to do point in time recovery of your database (irrelevant to the Portal)
3. When something bad happens to your DB, you are guaranteed to lose some data, because you can only recover to last good backup. (This is either acceptable to the business or not. Usually it is.)
Thanks for your thoughts!

There are no dumb questions. 'Better' or 'worse' can mean different things from different angles. I won't recommend something to a customer that I saw in an article somewhere, or gained knowledge via hearsay. I have to have tried it successfully with a customer, usually though iterative tuning, testing and monitoring cycles.
With that said, I see nothing wrong with using NOARCHIVELOG mode for the portal, and am looking to find someone with experience using it with the portal; and I don't mean a portal with four communities and a scant thousand users. I am looking for something more on the scale of our mutual customer who had about 15 front end portal servers, and about 15,000 hits per hour. Who, incidentally, is happily using SQL Server in simple recovery mode, and was game to try it out in the first place.

Noarchivelog mode Recovery scenario

Hi,
We have a development server which has local unix file systems /u01-/u24 mount points. As many mount points are near to 100% our unix admin said they can't provide more space on the local file systems but we will be moving to EMC storage which has /u01-/u08 mount points. The databases on this server are in Noarchivelog mode. When they move to EMC storage i will copy (re-map) /u09-/u24 mount points data in the local file system to EMC storage /u01-/u08 mount points. After doing that i have to re-create the control file. When i am trying to open the database it will ask for media recovery. Since the database is in Noarchivelog mode i have no archive logs to apply. Please let me know in this scenario how to recover the database so that it opens without any errors. Appreciate your response.

Appreciate your response.If your database is in NOARCHIVE LOG mode.
1) First put in mount status,
2) Copy datafiles by RMAN.
copy datafile 1 to ' new location';
3) rename all the datafiles from local to Storage.
alter database renaem file 'old location' to 'new location';
4) If you want to change the controflile to SAN
take a backup of controlfile,
alter database backup controlfile as 'location';
5) shutdown
Edit the PFILE to change controlfile location(new) if ASM follow below one.
startup in nomount.
rman> restore controlfile from 'backup location';
5) Now startup will do , no need to recreate the controlfile.
If your datafiles are huge, then after copying all the files to new location, take the trace of the controlfile and recreate.

Noarchivelog mode in oracle

Hello,
When I try to set my database in noarchivelog mode, it asks me to mount it and make sure its not open in any instance.
I have mounted it and this is the only oracle instance on the server, still it doesn't go in noarchivelog mode.
Please advise.

ORA-01242: data file suffered media failure: database in NOARCHIVELOG mode

Hi All,
Need help from the gurus.
Currently we are in state unable to do anything.
Was using a database and all of a sudden it crashed. Tried to mount the database, open it, it failed. Also tried the recover and alter database open, even that failed. Errors are as follows.
Errors in file e:\oracle\product\10.2.0 \admin\devrevdb\bdump\devrevdb_p000_2620.trc:
ORA-00603: ORACLE server session terminated by fatal error
ORA-01242: data file suffered media failure: database in NOARCHIVELOG mode
ORA-00449: background process 'DBW0' unexpectedly terminated with error 1242
ORA-01242: data file suffered media failure: database in NOARCHIVELOG mode
In my spfile, the administrator has set only two control files and there is no mirroring and hence do not have another control file that will help me boot the db.
Please let me know how I should go about it. I am only a timebeing person trying to carryout a db activity. Any help would be of great help.

Hemant,
thanks for the reply.
I tried the way you suggested and it threw an error.
ORA-01145: offline immediate disallowed unless media recovery enabled
I searched and found that an additional tag of drop needs to be added to the command which you suggested.
ALTER DATABASE DATAFILE '<filename>' OFFLINE DROP.
i don't know what will the drop command have an effect ?
i have copied the data file to another location. Since i don't know much, i just want to be sure of what im doing.
if the above command is successfull, will it drop the datafile or the tablespace and i can no more use it. How can i use the copied datafile.
Thanks,
Sachin

Recover database in NOarchivelog mode :)

Hi all. How to recover a database wich is in noarchivelog mode? B-)
Suppose,
I have 3 redolog groups (with two members in each, the second members are located on another drive ). When first redo log group was 1/2 full I took a full backup. Then there were 2 switches from first to second and from second to third. Now the currnet redolog group - 3 (just started). At this point we faced media failer. How to roll forward changes using backup + online redologs?
Edited by: Junior Oracle DBA on Oct 16, 2008 1:53 PM

Restore your database cold backup (excluding redo logs).
Then issue this command :
RECOVER DATABASE USING BACKUP CONTROLFILE
provide the names of the last ACTIVE / CURRENT Redo Logs in the database when Oracle prompts for an ArchiveLog.
When Oracle has finished recovery to a consistent point in time, it will return to the command prompt without any error.
Now issue this command :
ALTER DATABASE OPEN RESETLOGS
You would have a Complete Recovery.
This is provided that Oracle had NOT cycled through all the Online Redo Logs since the time when the Cold Backup was taken. (If Oracle had cycled through all the Online Redo Logs, it would have overwrriten the oldest log because it wasn't in ArchiveLog mode).

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.

How to recover a PDB in noarchivelog mode?

Hi all,
Urgent! We have a PDB currently in mount stage after restoring and recovering from backup. Whenever I tried to open it or recover data file, I keep getting this error message:
Errors in file C:\ORACLE\diag\rdbms\us022348\us022348\trace\us022348_p000_8788.trc:
ORA-01113: file 9 needs media recovery
ORA-01110: data file 9: 'D:\ORADATA\12C\US022348\0FB7D663771D443E8DE2229B76E0DCA7\DATAFILE\O1_MF_USERS_B2TVTBL1_.DBF'
The CDB and PDB both are in noarchivelog modes.
Which command should I use to bring the database back?
Thanks!!

I tried these but no luck.
