Change DB_FILE_NAME_CONVERT

Oracle Database 10g Enterprise Edition
Oracle Enterprise Linux


I am trying to learn the Dataguard configuration on my laptop. Since I created primary databases and ensures same House on the same laptop using Oracle, I need to use db_file_name_convert and Log_file_name_convert. But I can't just change parameter db_file_name_convert. I use spfile.

I get the error ORA-2096. That this setting can be changed with these options.

Can someone tell me how to change this setting.

I tried different ways,

ALTER SYSTEM SET DB_FILE_NAME_CONVERT =('ABC','XYZ') SCOPE = BOTH;
ALTER SYSTEM SET DB_FILE_NAME_CONVERT =('ABC','XYZ') SCOPE = SPFILE;
ALTER SYSTEM SET DB_FILE_NAME_CONVERT =('ABC','XYZ') SCOPE = BOTH DEFERRED;
ALTER SYSTEM SET DB_FILE_NAME_CONVERT =('ABC','XYZ') SCOPE = SPFILE DEFERRED;

Whenever I am getting error 2096.

Hello
DB_FILE_NAME_CONVERT is not editable using change control system. you will need to put in file pfile and start your db using this file.

then this is the thing you are trying to define DB_FILE_NAME_CONVERT change the db name. his evil. This is used to change the location of the data file.

Let's say your prumary data has its data in f:\oracle\datafile files. but when it comes to the standby location, you do not have this place or do not want to keep to f:\ himself. then use this setting to change the structure of database pending directory.

ex:
SQL > sho DB_FILE_NAME_CONVERT parameter

VALUE OF TYPE NAME
------------------------------------ ----------- ------------------------------
db_file_name_convert H:\ORADATA\, F:\ORADATA\ chain

    Hello guys,.

    I have two servers:

    SERVER01 Production

    Server02 Standby

    I have these settings in the file pfile (standby):

    * .audit_trail = "db".

    * full = '11.2.0.0.0'

    * .sga_target = 1610612736

    * .standby_file_management = "AUTO".

    * .undo_tablespace = "UNDOTBS1.

    First question:

    Once the process is finished, I had create pfile from spfile, but is the same code that above...

    So, what is a utility I have these commands in standby mode:

    data *.db_file_name_convert='/U01/app/Oracle/oradata/bd','/data/BD/fichier ' (change directory)

    *.log_file_name_convert='/U01/app/Oracle/oradata/bd','/data/BD/onlinelog ' (change directory)


    ??

    If I can remove these commands (db_file_name_convert, log_file_name_convert - standby server) in sleep mode? some problem? How can I remove these commands?


    Thank you

    In Server 03 (new day), I alreadyhave/data/bd/datafile and/data/bd/onlinelog... Yes, in the case... is not necessary, I have these settings. You undertood now? I'll create the server03/data/bd/datafile and/data/bd/onlinelog, is equal to the server 02...

    After that, in my view, is not necessary I have these settings. You got?

    The parameters above may be omitted if the directory of the primary structure is the same in the standby mode, or if you configure settings DB_CREATE_FILE_DEST & DB_CREATE_ONLINE_LOG_DEST_n primary and secondary school with the correct values.

    OK, I got it. And I give you the answer in my previous post.

    In this case, you can reset or change or delete the pfile these parameters.

  • RMAN duplicate grave crashes when I'm trying to change the paths of the destination

    Hello community,

    I am trying to duplicate a database of PROD for a test environment using the basic backup technique. I test the script in double and everything works fine when the paths of the database "auxiliary" (the database that I am creating) have the same paths as the basis of the 'target' (the database of production). If I change the paths, the double has failed because it does not find a backup of controlfile:

    channel ch1: from the restore backup set data file

    channel ch1: restore the control file

    channel ch1: reading of the backup piece PROD_cf_c-2175092736-20151204-0 c

    channel ch1: ORA-19870: error when restoring backup piece PROD_cf_c-2175092736-20151204-0 c

    «"ORA-19507: failed to retrieve the sequential file, handle ="PROD_cf_c-2175092736-20151204-0 c", parms ="»

    This is the script that works, but if I have the same structure of directories in PROD and TEST (but this isn't a real scenario):

    run

    {

    allocate auxiliary channel ch1 device type sbt;

    Send "NB_ORA_CLIENT = xxx NB_ORA_POLICY = xxx, NB_ORA_SCHED = Full_Diario';"

    duplicate database for TEST PROD

    until 'sysdate-2/24.

    NOFILENAMECHECK;

    output channel ch1.

    }


    And this is the script that it does not work because I have the PROD and TEST different directory structure

    run

    {

    allocate auxiliary channel ch1 device type sbt;

    Send "NB_ORA_CLIENT = xxx NB_ORA_POLICY = xxx, NB_ORA_SCHED = Full_Diario';"

    duplicate database for TEST PROD

    until 'sysdate-2/24.

    SPFile

    control_files value ' / TEST/orabd1/ctl/control_PROD_01.ctl','/TEST/oralog1/ctl/control_PROD_02.ctl','/TEST/oralog2/ctl/control_PROD_03.ctl '

    db_file_name_convert value "/ PROD /", "/ TEST / '.

    the value log_file_name_convert "/ PROD /", "/ TEST / '.

    core_dump_dest value "/ TEST/oralog1/cdump".

    the value 'TEST' db_name

    Set diagnostic_dest ' /TEST/oralog2'

    instance_name must bring 'TEST'.

    all local_listener 'LISTENER_TEST '.

    Set log_archive_dest_1 ' LOCATION = / TEST/arch.

    the value of log_archive_dest_2 'LOCATION = NULL'

    ;

    output channel ch1.

    }

    I tried to restore a Netbackup file and it works. I try to duplicate a database when the structures of directories are identical and it works. Why it's a failure when I change the destination paths?

    Thank you!

    Marina.

    Hello

    We had a similar problem in our shop. In our case, that we never knew if she was related to Oracle or NetBackup, but we found a Bug of Oracle, so we think it was a problem with the Oracle.

    Bug 11783792  RMAN SEND command does not hold the value of the variable

    DOC - ID 11783792.8


    Rather than send 'NB_ORA_CLIENT = DCLI, NB_ORA_POLICY is BD_DC_2, NB_ORA_SCHED = Full_Diario';.

    try something like this:

    Run {}

    allocate channels ch01 type 'sbt_tape' PARMS 'ENV =(NB_ORA_CLIENT=DCLI) ";

    Send "NB_ORA_SERV =';"

    Restore settings

    output channel ch01.

    }

    Let me know if it helps.

  • ORA-02095 trying to change log_file_name_convert

    Hi all

    IV' just rebuilt a standby database 11 GR 2 under HP - UX (physical Guard standbyData)

    In the alert, I see errors related to the location of the online redo logs.
    I think that is has to do with the LOG_FILE_NAME_CONVERT parameter

    I redo logs in two locations, so I should use 2 pairs of parameters to convert the path from primary to standby.

    When I run: alter system set LOG_FILE_NAME_CONVERT = "/ oradata/primary", "/ oradata/sleep ', ' / FRA/primary", "/ FRA/standby" scope = both; It returns:

    ORA-02095 specified initialization parameter cannot be changed.

    How will I know Oracle redo log are in a different place at the backup site?

    If I query v$ log mode standby, location is false, as some redo logs it displays/FRA/primary and it is and must be/FRA/standby

    Thank you very much

    But I think you want "LOG_FILE_NAME_CONVERT.

    See this

    http://download.Oracle.com/docs/CD/B19306_01/server.102/b14237/initparams112.htm

    Should work the same way on 10 and 11. Would still use "ALTER SESSION".

    I would try this first: (after redesign and an editing tool)

    ALTER session set log_file_name_convert =

    ALTER session set db_file_name_convert = (not that)

    SELECT name, value, ISSES_MODIFIABLE, ISSYS_MODIFIABLE of the parameter $ v where name like '% log_file_name ';

    You should be able to create a pfile your spfile file, stop

    Change the setting in the file pfile

    and start again from the shape of the pfile to re-create the spfile for Data Guard.

    Who is?

    Or scope = spfile

    Might work too (less jacking autour)

    Best regards

  • db_file_name_convert - adding tablespace to db with logic dataguard

    Not sure if I am missing something or misunderstood something.

    Scenario - 11 GR 1 material db with a logical database (redhat linux)

    Primary (minor syntax errors excuse I can type here)

    alter dummy tablespace add datafile ' / primary/db02/oradata/PRIMARY/dummy.dbf' size 100M;

    On the logic of the day before... you are looking for the tablespace to add as

    /STANDBY/DB02/oradata/standby/dummy.dbf

    I put db_file_name_convert
    ' / / db02/oradata/PRIMARY "," / Eve/db02/oradata/STANDBY.

    The only error I see is that the standby cannot create tablespace/data file
    ' / primary/db02/oradata/PRIMARY/dummy.dbf'

    It seems not yet trying to rename the directory structure to match the pending file system.

    I tried to simplify using the
    'primary', 'sleep', 'PRIMARY', 'STANDBY '.
    etc.

    Apparently not even tried to change the file names.

    Any ideas? I'm wrong about what should be the db_file_name_convert?

    Daryl

    I've done some reading on your behalf manuals.
    Db_file_name_convert seems not to apply to the waiting logic databases.
    Standby_file_management do not apply pending logic databases.

    Which is more or less expect that the logical standby database reads the log file to roll forward, transformations of logs redo in SQL statements, which are not related to physical files.

  • DB_FILE_NAME_CONVERT parameter does not work?

    Hi all,

    I recently created a database of pending of the my original database.

    Details:

    RHEL 2.6.9 - 42.ELsmp
    DB Oracle 9.2.0 (Production DB)
    Oracle Forms 8.0.6
    Oracle 11i application server

    When I set the parameter in the i of the file as follows:

    DB_FILE_NAME_CONVERT =('/Oracle/oraprod/oaproddata','/U01/oraprod/oaproddata')
    LOG_FILE_NAME_CONVERT =('/Oracle/oraprod/oaproddata','/U01/oraprod/oaproddata')

    I restart the database and when he's back I check the data file setting v$ to see if the situation has changed. There can be no. I then show parameter convert and it is as follows:

    VALUE OF TYPE NAME
    ------------------------------------ ----------- ------------------------------
    db_file_name_convert string/oracle/oraprod/oaproddata, / u01/oraprod/oaproddata
    log_file_name_convert string/oracle/oraprod/oaproddata, / u01/oraprod/oaproddata

    I know that's it's okay.

    So why when I the location of application files it revert to the old location?

    Any help at all?

    Thanks to all who responded!

    Hello

    Yes, in the pfile file
    http://www.SC.EHU.es/siwebso/KZCC/Oracle_10g_Documentacion/server.101/b10823/create_ps.htm

    DB_FILE_NAME_CONVERT is useful for creating a database that is duplicated for purposes of recovery. It converts the file name to a new data file on the primary database to a file name on the standby database. If you add a data file to the main database, you must add a file corresponding to the standby database. Updating the database of relief, this setting converts the name of data file on the main database the name of the data file on the standby database. The file on the standby database must exist and be writable, or the recovery process stops with an error.

  • Change of credit card deductions

    I am from Pakistan. I just change my credit card information and for whom I had 1 USD charged twice within 2 minutes.
    When I haven't bought anything, why me is she charged in the first place and who has also twice?

    Hello

    When a payment card is added or updated in iTunes Store, iBooks Store, App Store or Mac App Store, we can make a request for authorization to your card issuer.

    It's not a real charge, just a check to ensure that your credit card is active and can be used when you pay for your transactions.

    When a temporary authorization hold is placed on your credit or debit card, it will be only for a small nominal amount. For example, in the United States, you might see a charge of $1.00 USD.

    These charges will be removed automatically from your card account and shall not be paid.

  • Change order number/special character artists

    I would like to know if there is a way to change the order of all the artists that begin with a number or a special character order. Currently, they are all sitting at the bottom of the list of the artist on the ipod (and iTunes) but I would like to have all displays at the top of this list.

    This is the sort order...  I think you would need to change the names of the artists so that they start with something that gets sorted at the top of the list in alphanumeric order.  For example, replace 10,000 Maniacs a_10, 000 Maniacs.

  • Can I change the default folder for new documents Pages?

    When I run the application Pages, the first thing I see is a Finder window. For some reason, this Finder window invariably opens, not with the Documents folder, but in a specific subfolder of the folder images. Sometimes I use this folder as source for the photos that I insert into documents, but I don't want to see this folder every time I run the application Pages.

    How can I control this behavior? I see nothing in the preferences page to set a default value.

    When you launch Pages, you will be presented with a file picker (not the actual Finder). The left sidebar will be a folder of Documents, you must select. At this point, you can simply stop Pages. He will remember to open in the last selected folder and on the content of the Document folder, you will see a file chooser. As long you open, edit, save, or export documents in the Documents folder, it will remember this folder.

    If you change the location of the folder memory, whether it is in the file picker, or save or export to another location of the folder, and then the next launch of Pages will direct you to the last used folder location and not the location of the Documents folder.

    There is no user parameter which can be set to always override the behavior of Pages above.
