Bringing up database without updated control files

You have just had to restore from backup and do not have any control files. How would you go about bringing up this database?

Do u have the Control files Backup in trace File(text of File of control file)..
other wise write a creat control File command.. Make the proper changes in the command...

  • Database information in control file

    hi, i want to know what is database information in control file(reset logs scn and timestamp)
    what this information is .as the control file contains checkpoint information .i.e it also contain scn.how does this database information related to archivelog which is applied to datafile and does redo log contain scn information.
    thanks in advance.

    control file contains all the infromation about the database like scn, database name, database created date, datafile and location, logfile and location, max log group, and so many infromation.
    But this is the common question, before post your question kindly check in the internet, if you dont get any answer then post your question here.
    Cheers

  • Run a database without a dbf file

    Hi, can anybody help me? I need to run a database whose several (non sytem) dbf files are missing. There is NO backup. I only need access to the remaining dbf files but I cannot run the database. Can I replace the files with some kind of stubs? Thanks a lot.

    1. shutdown the database
    SQL> SHUTDOWN IMMEDIATE;
    If it's not working or hanging then
    SQL> SHUTDOWN ABORT;
    2. Startup the database in mount state
    SQL> STARTUP MOUNT;
    3. Find out the missing datafiles -
    select d.file#, d.status, d.enabled, d.create_bytes, d.name
    from v$recover_file r, v$datafile d
    where rf.file#=df.file# and rf.error = "FILE NOT FOUND"
    4. Create the datafiles (which were missed)
    SQL>- alter database create datafile '/path/filename.dbf' as '/path/filename.dbf' size xxx reuse;
    Note: Make sure that the path and size are the same )
    5. If the file is offline, then bring in online
    SQL> alter database datafile '/path/filename.dbf' online;
    6. Recover the database
    SQL> recover database;
    7. Open the database
    SQL> alter database open;

  • RECREATE DATABASE Using CONTROL File After SUSPEND Database

    Hello All,
    Does someone can tell me if he does achieve recreating a database using "Backup Control File" after putting database in "suspend" mode?
    The procedure looks like this :
    1 - Alter DATABASE Suspend
    2 - A Snapshot of the filesystem where the oracle datafile are located
    3 - Copy of those files to another file systeme
    4 - Startup setting a new database name
    Does someone as do it successfully ?
    Thanks for your answer

    Carlos,
    I tried to do it without putting the tablespaces in backup mode and it didn't work for me. At that time adding the backup mode wasn't a big deal for me, so I didn't investigate the problem thoroughly.
    Logically thinking you sould be able to do:
    1. suspend database
    the SCNs recored in datafiles headers could be incosistent at this point
    2. make a snapshot
    3. mount the backup database
    4. run recover until cancel using backup controlfile - I don't think you can avoid this step in case if you have inconsistent SCNs in the datafiles headers - you'll need to synchronize them
    5. open resetlogs.
    the suspend database should eliminate the possibility of inconsistent data within a block during the backup.
    Just out of curiosity - why don't you want to put the tablespace in the backup mode?

  • Problems creating control file in RMAN duplicate database

    There is so much detail involved in this operation that I don't know what might be useful, so I'll start simple. I'm attempting to clone a database on the same host using RMAN "duplicate database". I finally got all the setup done, the OS authentication hurdles hurdled, etc. and entered the command:
    duplicate target database to COPYCH2M until time "to_date('March 15 2012 12:00:00', 'Mon DD YYYY HH24:MI:SS')";
    The first time I got:
    ORA-19504: failed to create file "/u01/app/oracle/oradata/COPYCH2M/control01.ctl"
    ORA-27040: file create error, unable to create file
    Linux-x86_64 Error: 2: No such file or directory
    There was nothing in the Oracle instructions about manually creating the directory, but I did so, thinking that might be the problem. And it created the control files! But then I got the following:
    RMAN-00571: ===========================================================
    RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
    RMAN-00571: ===========================================================

    RMAN-06136: ORACLE error from auxiliary database: ORA-00201: control file version 11.2.0.0.0 incompatible with ORACLE version 11.1.0.1.0
    ORA-00202: control file: '/u01/app/oracle/oradata/COPYCH2M/control01.ctl'
    Sounds straightforward, if frustrating, right? Apparently you can't duplicate a database that's not in the exact same version. But:
    1) The backuppiece we got the control file from was from last November.
    2) The version of Oracle has not been updated since that time.
    How can a file created by this version be incompatible with this version? Where is it even getting 11.1?
    Thanks, I'm hoping this is easy but I can post more info if needed.

    >

    >
    The database is limited as to what it can create. Since you defined where you wanted the controlfiles to go (pfile/spfile), it's up to you to make sure the directory is valid and exists. :)
    >

    >
    As for your controlfiles, make sure the compatible parameter is set the same on both the source and the target unless you are using the default (11.1.0.1 for you, and you aren't)
    Keep going, you'll get there. RMAN duplicate is a great feature.
    Good luck.

    Check the value for the parameter "COMPATIBLE" in the source and standby database instance parameter files.
    "COMPATIBLE" should be the same.
    See http://download.oracle.com/docs/cd/B19306_01/server.102/b14239/create_ps.htm#i70517
    "... ensure the COMPATIBLE initialization parameter is set to the same value on both the primary and standby databases"

  • Creating a control file copy with ASM

    Configuration is Oracle 10.2, RAC, and ASM (Automatic Storage Management). I would like to create a second copy of the control file.
    If this wasn't ASM, I could just bring down the database, copy the control file using an operating system command, modify the pfile to reference both the original and new copy, and then restart the database.
    Since this is ASM, I cannot use an operating system command to copy the control file, and RMAN "BACKUP" (which is the only way I know to make a copy of the control file) will only work if the database is up. When I "restore" the control file using RMAN and change the pfile to reference both control files I get a message like the following when attempting to start the database:
    ORA-00214: control file '+ASMGROUP1/db1/controlfile/current.271.566646845'
    version 2241 inconsistent with file
    '+ASMGROUP1/db1/controlfile/current.268.566661765' version 2236
    Soooooo, how do I make and implement a second copy of a control file using ASM.
    Thanks

    Hi.
    This is not testet so presede with caution as it is meant as a discussion ;-)
    As I see it there is no logical way to extend the instance by adding a controlfile.
    The following procedure might work (has not been tested)
    I think you have to make a controlfilebackup with the database closed in normal mode using RMAN.
    Further you might be able to edit the pfile with create pfile from spfile and further create spfile from pfile. Extending the controlfile parameter to represent number and names of controlfile needed.
    With this done, the database is closed normal with a controlfile copy presented somewhere on the filesystem.
    startup mount;
    restore controlfile from '<backup controlfile location>'
    alter database mount;
    alter database open;
    Any thoughts about this procedure guys?

  • What is Control file ?

    Hi Gurus,
    Please explain me that what is Control file and what was the purpose of it in SAP Oracle DataBase.
    Thanks.

    Hi Kalyan
    <b>What Is a Control File?</b>
    Every Oracle Database has a control file, which is a small binary file that records the physical structure of the database. The control file includes:
    The database name
    Names and locations of associated datafiles and redo log files
    The timestamp of the database creation
    The current log sequence number
    Checkpoint information
    The control file must be available for writing by the Oracle Database server whenever the database is open. Without the control file, the database cannot be mounted and recovery is difficult.
    The control file of an Oracle Database is created at the same time as the database. By default, at least one copy of the control file is created during database creation. On some operating systems the default is to create multiple copies. You should create two or more copies of the control file during database creation. You can also create control files later, if you lose control files or want to change particular settings in the control files.
    <b>Guidelines for Control Files</b>
    This describes guidelines you can use to manage the control files for a database, and contains the following topics:
    Provide Filenames for the Control Files
    Multiplex Control Files on Different Disks
    Back Up Control Files
    Manage the Size of Control Files
    Role of Control File will remain the same even when you use Oracle with SAP. Just there will be some more entries in the file.
    Refer the link below as well:
    http://download-east.oracle.com/docs/cd/B19306_01/server.102/b14231/control.htm#i1006143
    Hope this should clear you doubt.

  • Bursting control file for Printer not working in WINDOWS ENVIRONMENT

    Hi,
    We are trying to print xml publisher report output (PDF) using bursting control file. Is not wokring.
    We are using ebs (R12.1.1) on Windows environment.
    Any pre-requisite setup (ie. cups config) should be done before printing using control file. Please guide me i am not having knowledge in printer setup and printer part..
    Thanks in advance

    Hi Hussein,
    Yes, I am able to print seed concurrent report (o/p -text) to that printer (method:- giving the printer name and copies by clicking " Option " in SRS window.. )
    When i do the same for xml publisher publisher report to the same printer , its not working using bursting control file.
    I too made the test in xml publisher report without bursting control file , there i faced another new issue. Let me explain
    1. We are using RDF as data source . here o/p :-" XML "
    2. We are using RTF as layout. In template definition, i chose the default o/p type as :- "HTML"
    3. When i submit the request, i choose the printer which is working fine for printing seeded report. (method:- giving the printer name and copies by clicking " Option " in SRS window.. )
    4. My printer getting prints HTML tag, instead of desired o/p. I wondered after seeing the printout.
    5. I cross checked by clicking view output, its showing me the exact html output as per RTF layout.
    Dont know wat happening ??? Help me out.
    i did the same for changing default output type in template definition to RTF,PDF.. its printing source code of the output type instead of printing output.
    Thanks & Regards,

  • Database Recovery using Archive files

    Dears,
    Due to some issue our database get crashed.
    We have saturday night offline backup and archive backup till yesterday night.
    We have restored offline backup and system is Up but it is on saturday night state.
    We want to apply these archive files to make the system state to current.
    In restore our control file also get replace with our saturday night control file status.
    We have copied our archive files in oraarch directory.
    Now when using brtools I am applying archive files:
    Command executing in brtools:
    recover from '/oracle/<SID>/oraarch' database
    it shows
    unknow command beginning
    No recovery required
    On sqlplus also when I execute
    sql>recover database;
    It shows no recovery required.
    When I give command:
    sql>recover database using backup control file;
    it ask for some {file name| AUTO | CANCEL}
    I give first file name of oraarch it shows "Can not access the file".
    File permissions are ok.
    I give AUTO, It also then do not do anything.
    Please suggest the correct method to make my system in latest current date.

    Hi Shivam,
    This is absolutely normal that during the restore your control files will be replaced by the old one which were backed up during database backup.
    Logic is that you can not apply the redolgs which are having the timestamps older than your  restored datafile's / controlfile's timestamp.
    If your DB is not yet opened, you can check the status of your database using below command which will tell you, till what timestamp your data is restored or currently available.
    select to_char(CHECKPOINT_TIME,'yyyy-mm-dd:hh24:mi:ss') from v$datafile where file#=1;

    > From command I want to know "from backup control file"....Do SAP take backup of control file as in system only old is

    recover database using backup controlfile.....  this command does not backup the controlfile . this will make use of old controlfile only which came along with the restore  and start the recovery using this controlfile only.
    Its just make use of available controlfile ..No backup will be triggered.
    Please make a note that after DB restore; ..recovery is possible only in case database is not yet opened in OPEN state.
    Cheers !!!

  • What is the difference  between  data file  & control file

    what is the difference  between  data file  & control file

    Dear Deba s
    Control file
    Every Oracle Database has a control file, which is a small binary file that records the physical structure of the database. The control file includes:
    The database name
    Names and locations of associated datafiles and redo log files
    The timestamp of the database creation
    The current log sequence number
    Checkpoint information
    For more info look into these
    [Control File Basic|http://download-east.oracle.com/docs/cd/B19306_01/server.102/b14231/control.htm#i1006143]
    Data File
    You manage Data File in your Oracle database as part of Space Management. You can extend, create, drop, and alter tablespaces.
    You especially need to avoid tablespace overflow, which is when a tablespace runs out of freespace in the allocated file or files. This happens when an object requires a new extent but there is either no freespace or insufficient freespace in the tablespace
    For more info look into these links
    [Data files |http://help.sap.com/saphelp_nw04/helpdata/en/98/5dd5890f32274aa884e45e736752a2/frameset.htm]

  • RMAN only backing up 2 out of 3 control files

    Hi, I have noticed my RMAN backup only backs up 2 of the 3 control files I have defined for my database.
    Is this normal behaviour for RMAN ( since it only needs the 2 and effectively can create others from them ).
    I don't see any errors in relation to the backup
    I am using 11gR2. When I go into OEM Db Control and look at AVAILABILITY - MANAGE CURRENT BACKUPS I see 3 entries,
    2 for the Control Files and 1 for the database files. Yet my database uses 3 control files !
    Can anyone explain this please ?

    Can anyone explain this please ?Actually RMAN backs up only one control file. You have three "multiplexed" and "same" controlfiles. If you want proof, delete them all except one, change CONTROL_FILES parameter in initialization file and start the db. It will start.

  • Database restore without temp, undo and control files.

    Hi All,
    You might found this question silly but I don't know so asking this question here.
    I have cold back up of the database. Now, I want create clone of that database, but I have some different paths for the DBFs so I will create new control file after restoring the database.
    Now, I know that I don't need control files and tempfiles to be restored. I have 10 undo files in backup but on the new clone database I don't need all 10. I want only 5. So can I do the restoration without undo , temp and control file and later on add undo and temp?? and if yes then tell me that can I add them at mount level??
    This is my first restore, Please guide me its very urgent

    Therefore, we do a RECOVER with a CANCEL to simulate an Incomplete Recovery.Completely agree with you Hemant. And the links you've provided,i've gone through many times. Excellent description.
    I just wanted to know in above(OP's) scenario if he has complete cold backup(includes online redo logs), does he really need open reset logs or any recovery?
    Regards!no , if you have cold backup with online redo log files then i don't think so you need to open database in resetlogs.Resetlog is always after incomplete recovery or recovery using backup controlfile or you dont have redo logs.
    I am completely agree with you that with given scenario for the cold backup undo tablespace would not be part of recovery and you can
    -offline drop undo tablespace file
    -create another one undo tablespace and its undo datafile
    -point spfile to that newly undo tablespace
    I think Aman is saying in the context of restore and recover online database where undo tablespace create a vital role in database recovery, the undo blocks roll back the effects of uncommitted transactions previously applied by the rolling forward phase.
