What data/control files to backup?

Dear All,
I can't perfom the proper backup - no room at the servers at the moment so I thought of making physical copies of datafiles and maybe control files. Though I'm not sure whether it's save or not and actually what files I have to take. Should I shutdown the database first hand?
If anyone did the same thing before please help)))
Thanks in advance
Marina

Hi,
Before planning the backup, Check for the following things.
1. Archiving mode of database(archive log or nonarchivelog).
2. How critical is the database.
If the database is in noarchivelog mode then you should shutdown the database first and then take the physical backup of All datafiles, control files and Parameter file.
If the database is in archivelog mode then you can simply take a online hot backup of the database. In the documentation you can get the method of taking hot backup.
Hope it helps.

  • 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.

  • Control File Auto Backup Alert Log

    Hello-
    Is there a parameter in the 11g database that needs to be configured to write to the alert log when the controlfile is auto-backed up ?
    I have this configured but there are no entries in the alert logs for 11g databases.
    I do have them in my 10g alert logs.
    Thanks-

    No there is no such parameter.
    It seems that Oracle 11g does not write anything to alert log when control file is auto backed up but instead writes to a trace file in diagnostic_dest directory tree:

  • How to recover datafile.when control file auto backup is off

    hi friend
    i took hot backup of my database using following command
    rman>backup database;
    in my case controlfile auto backup is off.
    and i have lost my all controlfiles as well as datafiles except spfile.
    i have recovered control file using dbms_backup_restore package.
    know i am able to mount database using following command
    rman> startup mount;
    when i wrote following command
    rman> restore database;
    i got following error
    RMAN-06023: no backup or copy of datafile name found to restore
    enven i have backup of datbase.
    can anybody tell me how to recover datafiles in this case.
    thanking you
    sohail

    hi,
    I think you might have a problem here as the error from RMAN is described in the following metalink note
    Doc ID: Note:100565.1
    You should change you backup script to be something like
    rman {
    backup database include current controlfile;
    do you have any earlier backups of your database?
    regards
    Alan

  • Control File Backups

    Hello-
    I was looking over some configurations that was setup by another DBA.
    There are 3 control files created but they all are on the same disk/directory.
    Control file auto backup is on to tape.
    If there was a hardware failure and all three control were corrupted/lost then a backup would be used but
    full recovery and RESETLOGS would be needed which would lead to redo data loss.
    If I configured 1 control file on a seperate disk. I would be able to copy this one and create 3 files again and the database
    would be started again without needing recovery if all else was fine.
    If the control keeps track of redo logs SCN, Archive logs history and RMAN backups when these change then wouldn't another control file backup/ trace need to be done ?
    Control File Trace only alllows to rebuild the database not to copy. How often is the need to taken ? Every change in the database ?
    Backup to the Flash Recovery is another backup not an updated copy to copy from but to restore/recovery with.
    Do have have these theories correct and my best setup would to send at least one to another disk.
    Thanks-

    If there was a hardware failure and all three control were corrupted/lost then a backup would be used but
    full recovery and RESETLOGS would be needed which would lead to redo data loss. No. If you lose all three controlfiles, you either
    a. RESTORE a backup of the controlfile
    OR
    b. CREATE CONTROLFILE (from a script)
    In either case, you do NOT need to do an INCOMPLETE Recovery. You will be doing a COMPLETE Recovery (if you have the Online Redo Logs). However, an OPEN RESETLOGS is still required. The %r in the log_archive_format since 10g allows ArchiveLogs to be retained through ResetLogs.
    If the control keeps track of redo logs SCN, Archive logs history and RMAN backups when these change then wouldn't another control file backup/ trace need to be done ? If you RESTORE the controlfile you lose no information. However, you still have to OPEN RESETLOGS.
    If you do a CREATE CONTROLFILE, yes, you lose information about ArchiveLogs history and RMAN Backups.
    You can issue a CATALOG command to re-catalog available Backups.
    Control File Trace only alllows to rebuild the database not to copy.A Control File Trace is to recreate the Controlfile. Not rebuild the database.
    Backup to the Flash Recovery is another backup not an updated copy to copy from but to restore/recovery with. I don't understand what your statement or question might be here.

    Now, if it not possible to get above backup piece back, then how to proceed with restore with backup piece DF_L0_HFM11PRD_10112012_l8npv5b6_13992_1 as it also has control file backup and available on disk, not obsolete. I can understand the reason for marking CF* file as obsolete because of redundency 1. But how to proceed with restore with available backup ?

    Hello;
    I would change my configure for one :
    RMAN>CONFIGURE CONTROLFILE AUTOBACKUP ON;Would use this to check :
    list backup of controlfile completed before <date>And would catalog everything again just to be sure before starting the restore.
    You may have to catalog use the control file piece to avoid the error.
    RMAN> catalog backuppiece ...Another idea is to test the restore using something like this :
    RMAN> run {
            set until time "to_date('2012 NOV 17 07:00','YYYY MON DD HH24:MI')";
            restore controlfile preview;
          }Best Regards

  • Snapshot control file

    Hi,
    I am interested in time of snapshot control file creation.
    I have read that snapshot control file is created before the backup take the place. I have tried to take the simple rman>backup database command, but I have seen that snapshot control file is created after all backup process (I have seen the time of creating the snapshot control file).
    Can anybody tell me about this? When the snapshot control file is created (before backup, maybe in the memory, because I can't see it on the file system).
    Regards,
    Dragan

    Hi,
    I have read this sentence from Oracle Database 10g RMAN Backup & Recovery:
    RMAN needs to get a consistent view of the control file when it sets out to make backup of every datafile. It only needs to know the most recent checkpoint information and file schematic information at the time backup begins. After the backup starts, RMAN needs this information to stay consistent for duration of the backup operation; in other words, it needs a read consistent view of the control file. With the constant updates from the database, this is nearly impossible - unless RMAN were to lock the control file for the duration of the backup. But that would mean the database could not advance checkpoint or switch logs or produce new archive logs. Impossible.
    To get around this, RMAN uses the snapshot control file, an exact copy of your control file that is only used by RMAN during backup and resync operations. At the beginning of these operations, RMAN refreshes the snapshot control file from the actual control file, thus putting a momentary lock on the control file. Then, RMAN switches to the snapshot and uses it for the duration of the backup; in this way, it has read consistency without holding up database activity.
    I must ask you if I am using control file only (not recovery catalog) what is happening when I am executing simple RMAN command> backup database;
    You have said that I don't create snapshot of control file at that moment, only at the end of the backup process (I have also try it in my environment and snapshot is created at the end of the backup process).
    How RMAN knows what to backup (which files), he takes this information from original control file (not from snapshot) I suppose.
    What is happening when he finished backup of some backup set, he writes that information again in original control file I suppose.
    And at the end of all process why he takes snapshot of control file (to backup control file from it, not from original control file, because control file is always changing, need to lock it). In that snapshot control file (and in the its backup) we will have the pointers on files that are made after the backup process started (is this true).
    Thanks,
    Regards

  • Upgraded to 10.2.0.2.0, but problem with 'identifying control file'

    I just applied the metalink patch to upgrade from 10.2.0.1.0 to 10.2.0.2.0 in order to install the SOA Suite. It was a clean install for 10.2.0.1.0, followed by applying the patch. I am now trying to run the new database, but I get an error:
    ORA-00205: error in identifying controle file, check alert log for more info.
    I edited by init.ora file, and the two control files are there as (ora_control1, ora_control2).
    Any help would be greatly appreciated.
    Kind regards,
    Anthony

    We had a similar issue and had to fix it by copying all the data files and control files to backup then ...
    1) run database creation assistant to delete the database
    2) using database creation assistant, create a new database with the same name
    3) shut down the new database
    4) leaving the new spfile in place, copy all the backups back over including controlfiles.
    5) startup the database.
    Don't know if it will help in your situation or not, but worth a try if someone else has the same type of problem.

  • Sqlldr and control file

    Howdy:
    I'm running Oracle 9i (9.0.2) on Redhat Linux 7.3.
    I am trying to append data from a flat file into a
    table where one of the field is timestamp(6).
    The data has fractional seconds and looks like so:
    [snip data]
    2002-12-08 22:29:38.216712
    [snip data]
    I want to use sqlldr to load the data, but when
    I try to create the control file, I am getting
    errors telling me my method is wrong.
    In my control file, I am trying to do things like:
    [snip versions of the 'UPDATED' timestamp field]
    * UPDATED TIMESTAMP "YYYY-MM-DD HH24:MI:SS"
    * UPDATED TIMESTAMP "YYYY-MM-DD HH24:MI:SS.FFF"
    * UPDATED POSITION(132:151)"TO_DATE(:UPDATED, 'YYYY-MM-DD HH24:MI:SS')"
    [snip versions ...]
    I am having no success.
    Can someone give an example of how to create
    a control file for sqlldr when defining a
    timestamp field with fractional seconds six
    digits past the decimal?
    Thanks!

  • Mv control files, redo.log, database fies

    Hello,
    I installed Oracle 10.2. on Unix.
    we have created file systems for our data/control files.
    some how we missed that part to define location for dbf, control & redo.log files during installation.
    My question is how to mv all control files, redo.log and dbf files to one location to another.
    for. eg:
    currently there are installed in /opt/oracle/oradata.
    now i want o move in /u03/oradata.
    Please note:
    Prior to that I'd like to put in archive log mode.
    shutdown immediate;
    startup mount;
    alter database archivelog;
    alter database open;
    DN

    For DB and Redo files
    conn / as sysdba
    shutdown immediate;
    startup mount
    host
    $ cp old_name new_name
    $ exit
    alter database rename file old_name
    to new_name;
    alter database open
    host
    $ rm old_name
    $ exitFor control files
    1. Shut down the database.
    2. Copy an existing control file to a different locations, using operating system commands.
    3. Edit the CONTROL_FILES parameter in the database's initialization parameter file to add the new control file's name, or to change the existing control filename.
    4. start the database.

  • 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]

Upto this i was clear, but now i cann't understand when you actually dropped the control file from you database(in running stat) how can you perform "alter system checkpoint" and other "alter tablespace.." command? Once controlfile is inaccessible, oracle database is not suppose to function.

  • How to create parameter and control file like filename + date

    Hello there
    I am trying to create parameter and control file with following command
    in SQLPLUS
    create pfile='/u03/oradata/WEBDB/backup/initWEBDB.ora' from spfile;
    In RMAN
    copy current controlfile to '/u03/oradata/WEBDB/backup/cf_longterm.cpy';
    how can I put date at the end of filename like
    initWEBDB8jan06.ora and cf_longterm8jan06.cpy
    Thanks in advance

    ASM is reliable but a smart DBA is very careful. If ASM is doing mirroring this is like RAID doing mirroring. What happens if you accidentally delete one copy ... the other one disappears instantly. Not a good idea.
    With respect to redo logs you need a minimum of three groups, two members, and one thread per instance. So a 2 node cluster should, at a minimum have 12 physical files.
    Not mirroring the redo logs, assuming multiple members, is not as critical.
