How to recover Database 10g

Hi
1. I have oracle 10g installed on D drive, and my window on C drive is corrupted.
2. I have installed fresh windows, but now my Oracle 10g Database is not functional.
3. How i make it Functional again, i dont want to install again 10g database, as it lose my all previous data.
Help as soon as possible.
Regards.

I think the main problem you are facing now is this. You lost your pfile/spfile wich was in the ORACLE_HOME directory (wich i suppose was on dirve c?) now you need to do very difficult tusk.
Get from internet an example of standart pfile and put it in $ORacle_HoME/dbs with the name initYOURDBNAME.ora and then start your database. All will be allright.
P.S. in the future store pfile /spfile in your oradata with a link to dbs. Because if you lost your datafiles, it will be usefull to lose pfile as a bonus. You don't need spfile if u lost datafiles. Please allways copy all database files on a floppy, to prevent a complete datalose. Also consider an archivelog mode. Sometimes it saves a lot of stuff. Hope it helps.

    Hi,
    why you create trace file ? and if you did that then you must have trace your ctl file after adding the tablespace for your db.so your ctl file will have registered the name of newly created tablespace.and if you do not have backup of ctl file which dosent contain the name of newly created tablespace then how would you recover your tablespace ? if you want to achieve your disered thoughts then add the tablespace and then backup of your full db then shutdown your db and delete your ctl file and data file.now open your db in nomount mode then restore your ctl file and datafile.
    thanks

  • How to Recover database from old backup and full archive log file

    Hi Oracle expert!
    I met problem when restore my oracle database.
    In my case:
    - My database version: 10.2.0.2
    - I have a database full backup (01-Nov)
    - I have all Archived log file from (01-Nov -> 05-Nov)
    - My database drop in 05-Nov with disk error (no datafile, no redo..).
    - I have no any RMAN backup from (01-Nov -> 05-Nov)
    How can i restore my database to 05-Nov?
    Thanks

    Hi Chinar.
    When i used RMAN flow as your step, but i met the problem!
    - After recover database i select sequence#, applied from v$archived_log;
    --> it apply newest archived log that i had.
    - but when I select Data from table created between 01-Nov to 05-Nov, it not found!
    Not the same way the step:
    SQL> RECOVER DATABASE USING BACKUP CONTROLFILE UNTIL CANCEL?
    It apply newest the same archived log i had table created between 01-Nov to 05-Nov.
    How can i do with RMAN to recover my table?That is not possible,if your all available archive logs applied using rman or through sqlplus(recover database using backup controlfile until cancel) and one of these logs contain your table then there are not any problems.So there are not any difference between recovery using rman and user managed(using sqlplus),but there main matter is applying all archive logs.So first check through rman list copy of archivelog all or list backup of archivelog all and identify there in rman repository is any information or not about these logs.

  • How to recover database without archive files

    Hello,
    I've a test database without archive files and I need to know how to recover it without using archive files.

    There are serveral information missing in this posting and as a support personnel, I would like to find out more when I see postings like this.
    1. This person wants to "Test" his backup and recovery in NOARCHIVELOG mode.
    2. He/She did not say his database had already crashed or had a problem.
    3. He/She did not give any indication the kind of scenario he wants to recover from.
    4. He/She did not mention the state of his database at the time of he posting.
    5. He/She did not mention the Release of his Oracle Server or Platform.
    6. He/She did not mention the type of backup he already has in place (although provided later as Full COLD Backup). How "genuine" is the back?
    7. What actions has already been taken to attempt recovery.
    In my support experience, I normally would go through a list of questions witht he use/client to get the full picture of the current status of the database before I give answers that would worsen situations, especially in a Disaster Recovery sitaution.
    Personaly, I would suggest you have a look at the list above. One of the most important is number 3 (The Recovery Scenario), then number 4, number 6 and 7. Number 7 will determine the situation of your database. So, when you ask for SQL commands to use, there are different commands for different kind of recovery depending on what has gone wrong or what kind of file is damaged (Datafiles, Logfiles, Control Files, one tablespace, one table, entire database gone, etc).

  • How can recover database using only Full Export ?

    Hi,
    I have one query , i have only Full export is given database , after full export sucessfully
    database Crash by mistacally, how can recover it, i have only export is given no backup is taken (RMAN,COLD or HOT) statergy is use , How can recover it.

    You need to recreate the database from scratch as imp requires a working database.
    You could already do this by transforming the results from
    'alter database backup controlfile to trace', a trace file containing a 'create controlfile' statement, into a 'create database' script.
    After that step you apply your import. Everything after that import is lost forever.
    One would ask for a sanity check of management and personell of a company, which has no backup strategy in place.

  • How to recover database when all redo logs are losted

    pls help me in recovering the database when all the redo logs are losted

    In both cases he has to open the database in RESETLOGS option. So try:
    recover database until cancel;
    Then cancel the recovery, and
    alter database open resetlogs;
    If you want to check where your database is at then mount your database and issue:
    select group#, sequence#,first_change# from v$log;
    This will tell you the sequence and SCN of all the online log files then compare it with what it prompted when you issued recovery command.

  • How to recover database SYSTEM datafile get corrupt ?

    Database is in ARCHIVELOG mode, and the datafile belonging to SYSTEM tablespace gets corrupted. Up to what point can I recover the database ?
    A. Until last commit.
    B. Until the time you perform recovery.
    C. Until the time the datafile got corrupted.
    D. You cannot recover the SYSTEM tablespace and you must be re-create the database.
    and 1 more doubt :
    If redologfiles are not multiplexed and redolog blocks get corrupt in group 2, and archiving stops. All redolog files are filled and database activity is halted.
    DBWR has written everything to disk. What command can be used to proceed further ?
    A. recover logfile block group 2;
    B. alter database drop logfile group 2;
    C. alter database clear logfile group 2;
    D. alter database recover logfile group 2;
    E. alter database clear unarchived lofile group 2;
    Edited by: user642367 on Sep 18, 2008 8:45 PM

    1. A. Since the DB is in archivelog mode, so you can always restore and recover the whole DB including system tablespace datafile till last SCN generated provided the redo record is available in archive/online logfiles.
    2. E. Since only redolog is corrupted so archiver won't proceed and hence a db hang is obvious, So, in order to proceed further you need to clear online (un archived log file) and then db will work as usual. Care should be taken that you must take a full backkup of DB(cold backup wherever feasible) as soon as possible after issuing this command. As now you don't have redo info in archivelog files to recover the db in case of a crash.
    Please go through Oracle 10g DB Administrators guide (available on OTN) for more details.
    Thanks

  • How to recover database from .mdf file

    create a database of
    equal size to the one you're trying to attach
    shutdown the server (Stop)
    swap in the old mdf file (replace new .mdf file with .mdf file to be recovered )
    Location: C:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\DATA
    bring up the server (start) and let the database attempt to be recovered and then go into suspect mode
    put the database into emergency mode with ALTER DATABASE
    run DBCC CHECKDB (dbname, REPAIR_ALLOW_DATA_LOSS) which will rebuild the log and run full repair
    Your database will be available again but you'll have lost data and the data won't be transactionally consistent
    USE [master]
    GO
    ALTER DATABASE [RdmStoreInformation] SET EMERGENCY
    GO
    ALTER DATABASE [RdmStoreInformation] SET SINGLE_USER
    GO
    DBCC CHECKDB ([RdmStoreInformation], REPAIR_ALLOW_DATA_LOSS)
    GO
    ALTER DATABASE [RdmStoreInformation] SET MULTI_USER
    GO
    ALTER DATABASE [RdmStoreInformation] SET ONLINE
    GO
    This is a issue I had to fix and it's solution listed here for your reference(I gathered all the In-formations by surfing web)

    Interesting, did you get any errors trying to attach the .mdf file?

  • How to recover database using dbf file

    Hi all,
    My oracle database gets crash. But i have all the dbf file . But there is no controlfile,redo log file and pfile . So i have to create a database that will contain these existing dbf file.
    Can anyone tell what are the steps i have to follow ?
    Regards

    Does the datafiles comes from a cold backup or was database closed when disk crashed ?
    Well, what's your OS ?
    You need to write a new init.ora file, create the dba service if your under windows, and recreate the database with the command line, that will create controlfile and redolog.

  • Doubt in - recover database command

    Hello,
    I wanted to know the significance of - using backup controlfile
    in the sql command:
    recover database using backup controlfile until cancel
    Some background info-
    I am performing a system copy using Db backup-restore methodology.
    I generated a new control file using -
    1. alter database backup controlfile to trace;
    2. Editing the file, changing SID and renaming it to control.sql
    3. @control.sql
    So how is - recover database using backup controlfile until cancel
    different from - recover database until cancel
    in this scenario?
    Thanks.

    This is the best explanation i had found earlier which is well written
    If you were to recover the database with a current control file, Oralce will know the last SCN of the last checkpoint. So Oracle can use the information in the archived and online redo logs to apply recovery up to that SCN. This is called a "complete" recovery.
    If you do not have the current control file, your option is to use a backup controlfile. Which means Oracle does not know the SCN to stop applying recovery. So you tell Oracle that you are using a "backup controlfile" and that you will tell it when to stop applying redo by replying "cancel." When Oracle starts recovery, it looks at the datafiles to know the last time a checkpoint was performed on the datafile. Oracle now knows to start applying recovery to the datafile for all SCNs after the SCN in the datafile header. Oracle rolls forward transactions. But Oracle does not know when to stop, and eventually, Oracle applies recovery in all of your archived redo logs. You can then tell Oracle to use the redo in the online redo logs. Oracle will ask you where to find more redo. At this point, you tell it to quit applying redo by replying CANCEL.
    Hope this helps in explaining the difference
