Delete the database with lost initdb.ora

Hi guys. How can I remove database with file init lost? I just want to recreate the database (with recovery or restoration of the process)

1. I can't start because I do not have init.
2. I can't delete the database because I can't start.
3. I can't recreate database using dbca as the same name somewhere is:)

When you run "dbca" you can select "delete the database" and find the old name of the database?
If find... You can select and delete... dbca will ask... But you and click on remove in any case.

    Hi gurus,


    I'm stuck in a situation and need your help.

    We check if our backups are valid or not. So it gave me a new server and backups/archives to a 2 TB database I need to restore/recovery. I followed steps below.

    (1) copied the prod parameter file to test.

    (2) make the necessary changes in the init file.

    db_file_name_convert, etc..

    (3) start db in nomount mode.

    (4) restore the backup control file

    Restore controlfile to ' / oraback/ARCH/prod/backup_controlfiles/c-250795000-20141030-01';

    (5) mount the database.

    (6) created under the rman script and executed.

    Run {}

    Catalogue start with ' / oraback/RMAN/test "noprompt.

    Catalogue start with ' / oraback/ARCH/test "noprompt.

    Questions-

    -Restore completed successfully, but I found that few archives are missing.

    -I pulled from database to recover until cancel using backup controlfile; There is a below error

    ORA-01152: 1 no file has been restored from a sufficiently old backup

    ORA-01110: data file 1: ' / u02/oradata/testsystem01.dbf'

    -Then tried to restore the archive of available backup archive and few of archives have been restored.

    i.e. of sequence between 759529 and 759552.

    (1) how to proceed from here.

    (2) all the changes I need to do to the RMAN script. As I need to automate the process of restoration.

    (3) I don't want to use under hidden settings

    _ALLOW_RESETLOGS_CORRUPTION = TRUE

    _CORRUPTED_ROLLBACK_SEGMENTS = (Automatic Undo segments comma-separated list)

    Thank you for the support.

    You can not ignore the archivelogs.

    If the archivelogs are not available, you need a database backup that was created after missing the last archivelog point.

  • Refresh the production database to test the database with RMAN

    Hi experts,

    I want to refresh the production database to test the database with RMAN. You can help me please how to do this.

    I saw a lot of blog on the internet but not got a satisfactory answer.

    Reg,

    Thomas verrma

    Thomas

    Follow these steps

    1. on the server target

    a. Add entry in oratab

    b. create init.ora for target db copy of source

    c. If you use catalog

    connect to the RMAN catalog, you can use the double option to clone run below

    one.

    RMAN > Connect target sys /@trgt

    RMAN > Connect Catalog rman /@catalog

    b. check that the backup connects to the source and to collect information on the elements of backup that contains the backup controlfile

    c. restore the controlfile

    RMAN > set DBID = xxxxxxxx (DBID of the source db)

    RMAN > run

    {

    allocate channels ch1 type parms 'SBT_TAPE' = 'ENV = (NB_ORA_CLIENT =, NB_ORA_SERV =)';

    Restore controlfile from "/ c-DBID-xxxxxxxx-00';

    }

    Once the controlfile is restored, you can mount the db

    change the editing of the database;

    run

    {

    until ' TO_DATE (2014-SEPT-10 10:00 ', MY - DD - YYYY HH24 ') ";

    allocate channels ch1 type parms 'SBT_TAPE' = 'ENV = (NB_ORA_CLIENT =, NB_ORA_SERV =)';

    restore the database;

    recover the database;

    }

    ALTER database open resetlogs;

    stop immediately;

    bootable media;

    nest target = / = dbname

    change the system db_name set = scope = spfile;

    stop immediately;

    Startup mount

    ALTER database open resetlogs;

  • Delete the database on Windows

    Hello


    Could you please provide steps or relevant link to remove the Oracle database in the Windows platform?


    Oracle - 11.2.0.3.0

    OS - Windows 2003 32-bit

    Kind regards

    Bala

    In fact, I wouldn't use these steps. The main reason is that the DROP DATABASE command will not remove this annoying service. Instead, I would check the database is running, and then use the DBCA Wizard to delete the database. Not only this delete the database for you, it will be also make you the Windows registry (and therefore service) are supported properly.

    See you soon,.

  • register the database with the database Vault

    Version: 11.2.0.2.0

    Operating system: Solaris

    Can someone tell me please how to enter Oracle Database Vault with a database from command line without using DBCA.

    The doc oracle E23090-10 provides only through the DBCA Wizard. I'm having some trouble with my software x - manager, so I cannot use the DBCA Wizard and seeks to enter the vault of the database with the database by command line.


    Oracle database Vault is already enabled through 'chopt enable lbac' and 'chopt enable dv. Now all I do is register with the databases on the server.

    Thank you

    Hi DK2010, actually I found my answer in the metalink Doc ID 803948.1

    I have to run the dbca in silent mode and at the end of this doc, it's exactly what I need.

    "

    DBCA-silent - configureDatabase

    sourceDB-

    [- sysDBAUserName

    -addDBOption DV, WHO

    -dvUserName

    -dvAccountManagerName

    -dvAccountManagerPassword

    Now, the keystone of the database is registered with the database.

  • Create the database with a set of characters

    Hello

    I need to create a database with the character US8PC437 (platform Linux Redhat 5.4 64-bit, database version 11.2.0.3), but this character set do not appear when I create the database with the database assistant (DBCA).

    Any help will be apreciated.


    Best regards

    While AL32UTF8 is certainly recommended for the Oracle database character set, use only, if your application provider has confirmed that their application will work with a set of characters to multibyte database.

    To create a database US8PC437 (it is rarely a choice, in fact) with DBCA 11.2, select the "character sets" tab, once shown, then select the option 'Choose from the list of character sets' and uncheck 'Show recommended only character sets '. This will add US8PC437 to the "Database character set" drop-down list. Select "US8PC437" from the list and continue the process of creation.

    But first, contact your provider and ask a compatible Unicode version of your application.

  • Connect to the database with SQL * more: is TNSNAMES. ORA used?

    Hello

    We have a local database called DEV01 and a copy of this database in a data center. To be able to connect to both databases, the TNSNAMES file. ORA

    on the local database server (not the one in the data center) has the following entries:

    / * Entry for the local database * /.

    DEV01_local, DEV01_local. WORLD =
    (DESCRIPTION =
    (ADDRESS_LIST =
    (ADDRESS = (PROTOCOL = TCP)(HOST = server01) (PORT = 1521))
    )
    (CONNECT_DATA =
    (SERVER = DEDICATED)
    (SID = DEV01)
    )
    )

    / * Entry for the database in the data center * /.

    DEV01, DEV01. WORLD =
    (DESCRIPTION =
    (ADDRESS_LIST =
    (ADDRESS = (PROTOCOL = TCP)(HOST = server02) (PORT = 1521))
    )
    (CONNECT_DATA =
    (SERVER = DEDICATED)
    (SID = DEV01)
    )
    )

    When I connect to the local database server, I set the Oracle environment as follows:

    export ORACLE_SID = DEV01

    export PATH=/opt/oracle/app/oracle/product/9.2.0/bin:$PATH

    export ORACLE_HOME=/opt/oracle/app/oracle/product/9.2.0

    Now I start SQL * more as follows:

    Oracle # > sqlplus user/user

    SQL > select instance_name, host_name from v$ instance;

    INSTANCE_NAME HOST_NAME

    ---------------- ----------------------------------------------------------------

    SERVER01 DEV01

    As the SID is on two databases of the same (DEV01) I really don't understand how Oracle decides which of the SQL databases * more connects to.

    Is it the entry in the TNSNAMES file. ORA?

    But when I start SQL * more as follows:

    Oracle # > sqlplus user/user@DEV01_local

    SQL > select instance_name, host_name from v$ instance;

    INSTANCE_NAME HOST_NAME

    ---------------- ----------------------------------------------------------------

    SERVER01 DEV01

    or

    Oracle # > sqlplus user/user@DEV01

    SQL > select instance_name, host_name from v$ instance;

    INSTANCE_NAME HOST_NAME

    ---------------- ----------------------------------------------------------------

    DEV01 server02

    everything is as expected.

    Does anyone know who is the chosen database when just to connect with 'sqlplus user/user' (without the @DEV01 or @DEV01_local)?

    Any help will be appreciated!

    Rgds

    Jan

    When you connect to the local database that is connected to the server01, you need only specify the sid in the environment, in this case, Oracle tnsnames file to connect, actually uses, it uses any of the listener.  It uses what is called a connection needed.  It is purely a side connection server, and as long as the sid is located in the environment resolves to a database running on that server, you will be get connected.

    When you connect using the @connect_descriptor, like you second case, then Oracle will use the configured naming, including tnsnames, methods to solve the 'real' database  In this case, the auditor is required to create the connection to the database.

  • Backup the database with archiving logs lost

    How can I get a backup of the database when all archive logs have been lost?

    So, it looks that you use RMAN to back up, since all the archivelog went. You can do

    RMAN> crosscheck archivelog all;
    
    RMAN> delete archivelog all;
    

    then make a backup.

  • Delete the database during uninstall of the application

    Hello everyone, my requirement is to delte the database when we uninstall the application, I did a quick search in the forum, did not meet any results, hope that someone would be comup with an answer to my question.

    Help of any kind is welcome!

    Hi avi_yach,

    The files are not deleted on uninstall.

    You can try and set up a CodeModuleListener or add an application which will remove your files once your original application has been uninstall.

  • Cannot access the database with IP SCAN

    People,

    We have a RAC 11 GR 2 to 4 knots on EXADATA machine system. While we strive to connect with easy connect method as

    sqlplus system $ / password@node1-vip:1521 / ORCL

    It will correctly connect to the database. But while we use IP SCAN:

    sqlplus system $ / password@node-scan:1521 / ORCL

    It returns, ORA-12514: TNS does not currently of service requested in connect descriptor.

    However, the local settings and remote listener with correct values and nslookup return correct results. Please, advice on that.

    Kind regards

    Ali

    Local settings and remote listener were correct, that the listener SCAN was not record instances were. As a result, we removed and again fix the SCAN with grid services and then save instances with SCAN. So, it worked. Thanks to you two!

  • RMAN backup on the database with data file with corrupted block

    Hi friends,

    I have a problem with a database of oracle 11g XE on windows server 2003, the database is in production, it is open, is operating normally.

    The database has no backup configured before, so I put the database archiving mode and tried to backup using rman utility, but it show me some errors.

    First of all, it showed me:

    ORA-19501: error in reading file... SYSAUX. DBF

    ORA-27070: async read/write failed

    OSD-04016: error queuing an asynchronous i/o request.

    And when I passed the dbv on the SYSAUX file utility. DBF showed the fatal error.

    So, I switched CHKDSK utility on windows to repair the disc of the error. After that, run utility dbv and he passed and showed me the corrupt on SYSAUX blocks. DBF

    Then, came to rman and ran:

    RMAN > validate the logical database checking;

    State of the file marked corrupt blocks examined empty blocks high YVERT

    ---- ------ -------------- ------------ --------------- ----------

    3 0 1111 115840 78859075 FAILED

    Type block for lack of treated blocks blocks

    Index 0 0

    Other 38 114729

    After that: watching the content of v$ database_block_corruption;

    Show me a lot of lines like this:

    SQL > select * from v$ database_block_corruption;

    FOLDER # BLOCK # BLOCKS CORRUPTION_CHANGE # CORRUPTIO

    ---------- ---------- ---------- ------------------ ---------

    3 4440 1 FRACTURED 0

    3 4384 1 0 ZERO ALL THE

    3 4334 1 0 ZERO ALL THE

    ...

    33 selected lines.

    Finally I try to rerun rman and he shows me the error:

    ORA-19566: exceeded the limit of 0 blocks corrupt file C:\ORACLEXE\APP\ORACLE\ORADATA\XE\SYSAUX. DBF

    How can I do backup with rman? Maybe I can by pass the corrupt block?

    I'll be grateful for any help you can provide.


    =)

    It would be better if you try to find the reason of corruption and try to recover the corrupt blocks. A block corrupted in the backup would really not must use. But if you're ready to take backup, you can ask RMAN to ignore corrupt blocks and move forward.

    Use the pseudo-code for the backup

    Run {set maxcorrupte for the database to 10;

    backup tablespace sysaux ;}

  • create the database with Oracle Client link

    Hello together,

    on my machine Windows 7 with Oracle Client installed 12.0.1.0, I'm trying to create a database link to a database server, which runs on Oracle Standard Edition1 11.2.0.2.

    When I connect to sqlplus on the client with "sqlplus/nolog" and type the command:

    SQL > create SID of the database link

    connect to the user identified by passwd

    using "tnsnames.ora connection."

    I have a SP2-0640: not connected. OK, it is clear, because I use sqlplus with option/nolog. But client-side normally I have no database, where I can connect. So I think, there is no user, or?

    The database to which I want to connect is located in tnsnames.ora.

    Generally: Is it possible to use the Oracle Client to create a database link? Maybe there's another way to do this?

    A big thank you and best regards,

    David

    You don't seem to understand the concept of a database link.

    A database link connects two databases. Not a client and a database.

    You need to link up in a data source to a target database.

    The only thing you need is a client of sqlplus in sqlplus client, you need to connect to the source database.

    If you can't connect to the source database, you must present the statement to someone.

    You can not use the command DUPLICATE between platforms (see duplicate restrictions in the documentation). It is possible to perform a cross-platform via RMAN transport. This process is also explained in the documentation.

    Werner

    You have an additional complication, patch levels are different. Perhaps datapump here is a better solution - depending on the size of the database.

    And I hope that Solaris on x 86-64 (no SPARC), otherwise the next complication.
