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.

  • 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:

    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,

  • How to recover a PDB in noarchivelog mode?

    The CDB and PDB both are in noarchivelog modes.
    Which command should I use to bring the database back?

  • Restoring backup taken in NOARCHIVELOG mode

    Hi I have a test database in noarchivelog mode. The backup I am implementing involves:
    Shutting down the database in immedtiate mode. Taking a complete backup of the
    a) Datafiles
    b) Controlfiles
    c) Redo log files
    d) Parameter file
    e) Password file
    Now, when I want to restore in case of any media failure, I will copy all the above file to their respective locations.
    Here my question is that, do I require to open the database after restoring all the datafiles,controlfile and redo files(in particular) in the RESETLOG mode or as I will be overwriting the current useless redo log files with the backup redo log files, I can just open the database normally?
    What I am thinking is to open the database with alter database open
    Please comment with full explanation.

    >
    Your thinking is right :-) You have chosen the simplest but not necessarily most efficient or reliable backup method. You simply get the whole database back from backup, so there is no resetlogs necessary. But keep in mind that you lose all modifications since your backup.

  • 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 :

    The error was solved.

    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 .

    Because the database was not shut down cleanly. An open database is by definition "inconsistent" without the proper logfiles.

    > 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.

  • 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-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:

    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.

  • 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).

  • 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:

    set PATH=D:\oracle\product\10.1.0\db_1\bin;%PATH%

  • ORA-00258: manual archiving in NOARCHIVELOG mode must identify log

    Hi I am new to oracle streams. I am trying to setup a one way replication from one database to another using Oracle 10g (10.2.0.1.0) on Windows XP SP3 (32 bit).
    I ran the following proc as the streams admin schema:
    begin
    dbms_streams_adm.maintain_schemas(
    schema_names => 'XXCOW',
    source_directory_object => 'repl_exp_dir',
    destination_directory_object => 'repl_imp_dir',
    source_database => 'PWBSD',
    destination_database => 'PDVSD',
    perform_actions => true,
    dump_file_name => 'exp_app23.dmp',
    capture_queue_table => 'rep_capt_table',
    capture_queue_name => 'rep_capt_queue',
    capture_queue_user => NULL,
    apply_queue_table => 'rep_dest_table',
    apply_queue_name => 'rep_dest_queue',
    apply_queue_user => NULL,
    capture_name => 'capture_pubs',
    propagation_name => 'prop_pubs',
    apply_name => 'apply_pubs',
    log_file => 'exp_app23.log',
    bi_directional => false,
    include_ddl => true,
    instantiation => dbms_streams_adm.instantiation_schema);
    end;
    The script failed the first time because i forgot to configure the source database in archive log mode.
    The steps i followed to change to archivelog mode:
    SQL> select name from v$database;
    NAME
    PWBSD
    SQL> alter system set LOG_ARCHIVE_DEST = 'D:\data\oracle\oradata\PWBSD\archive' scope=both;
    System altered.

    I configured it in archive log mode and ran the proc above again.
    I got the following output this time:

    I ran the following to check the error:

    The output is:

    It seemed like it was still complaining about archive log mode,
    I verified that the PWBSD db is in archivelog mode by running the following:
    select name, log_mode from v$database;
    NAME: PWBSD
    LOG_MODE: ARCHIVELOG
    What could be the problem and how do i proceed to fix it?

    Hi Parthiv,
    The steps given by you is not clear.
    please try to fallow the steps given in the below link. It may be helpful to you to setup schema level streams:

  • 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.
