• restore / recover the control file

  Hello
  in 10g, I lost all the files of ctl and I want to restore/recovery of backups RMAN.
  Oracle documentation:
  

  6.4.1.4 Restoring a Control File When Using a Recovery Catalog
  Restoring a lost control file from autobackup is easier when using a recovery catalog than when using only the control file to store the RMAN repository. The recovery catalog contains a complete record of your backups, including backups of the control file. Therefore, you do not have to specify your DBID or control file autobackup format.
  
  To restore the control file, connect RMAN to the target database and the recovery catalog, and bring the database to NOMOUNT state. Then issue the RESTORE CONTROLFILE command with no parameters, as in this example:
  
  % rman TARGET rman/rman CATALOG catdb/catdb
  RMAN> RESTORE CONTROLFILE;

  After that I should publish any statement to RECOVER or change the editing of the database and alter database open would be enough?
  
  Thank you.
  Is there a complete senario anywhere?

  The restoration is correct.

  Please see the following:

  Dear all,

  While checking the database,

  Control the name of the database file is PROD

• Is there a way to recover the deleted files without using any software?

  Is there a way to recover the deleted files without using any software?

  Is there a way to recover the deleted files without using any software?

  # Software is necessary.

  First check the recylcl tray. If she isn't here, read the following:

  "Deleting" a file does not delete actually it brand just space be used. There are third-party programs that can sometimes recover deleted files. The problem is that the space used by the file is likely to be replaced very quickly, and this makes the unrecoverable file.

  So your chances of successfully recover this file are decent, if you try it again immediately after deleting it and quickly down. If you have used the computer since then (for example to read this answer and write that question), your chances may be very weak now.

  But if the file is large enough, it's still worth a try. Stop using the computer in question immediately, if you haven't done so already. Download an undelete program (in here is one: http://www3.telus.net/mikebike/RESTORATION.html but there are many other choice; do a search) on a friend's computer and bring it to you on a diskette, CD, or drive to the thumb.

  If that fails, your only recourse is to bring or send the drive to a professional file recovery company. This kind of service is very expensive and may or may not work in your case.

• How can I specify location of the control file when the manual creation of DB?

  DB version: 11.2.0.4

  OS: Oracle Linux 6.6

  The CREATE DATABASE command creates the control file.

  CREATE DATABASE command is executed once you start the instance in NOMOUNT State as shown below.

  SQL > startup nomount pfile=$ORACLE_HOME/dbs/initBRCPRD.ora

  SQL > create database 'BRCPRD '.

  MaxInstances 32

  MAXLOGHISTORY 1

  maxLogFiles 192

  maxlogmembers 3

  ..

  .

  .

  < snipped >

  When you create the database manually, we can define the control_files parameter in the init.ora as below and control file will be created at this location. Right?

  control_files = ("" / u01/oradata/BRCPRD/BRCPRD_control01.ctl","/u01/oradata/BRCPRD/BRCPRD_control02.ctl "")

  When I was generating the DB using DBCA GUI creation scripts, it asks to enter the location of the Online redo logs and control files.

  I entered my desired location. But, I couldn't find CONTROL_FILES parameter in the init.ora file generated the DBCA. This is why I got confused. I think that DBCA is internally somehow. So thought I'd post it here.

  Hi John, OP

  Just checked the init.ora file created by DBCA. Although the parameter CONTROL_FILES is undefined, db_create_file_dest = '+ DATA_DG1' was created. OMF default location is defined by the db_create_file_dest parameter.

  So, I could safely use this script for the manual creation of DB, and during the CREATE DATABASE command execution, oracle will place CONTROL_FILES + DATA_DG1 using the format;

  Hello;

  That's what I'd do:

  Primary backup (change in your directory as needed)

  RMAN RUN {
  allocate channel d1 type disk;
  backup format '/u01/backups/PRIMARY/df_t%t_s%s_p%p' database;
  sql 'alter system archive log current';
  backup format '/u01/backups/PRIMARY/al_t%t_s%s_p%p' archivelog all;
  backup current controlfile for standby format '/u01/backups/PRIMARY/sb_t%t_s%s_p%p';
  release channel d1;
  }
  

  Move the backup and duplicate like this:

  rman target sys/password@PRIMARY auxiliary /
  
  RMAN> run {
  allocate channel C1 device type disk;
  allocate auxiliary channel C2 device type disk;
  duplicate target database for standby nofilenamecheck;
  }

  I have not updated the database control file, now I get an error message:
  
  ORA-01157: impossible to identify or to lock the 202 data file - see DBWR trace file
  ORA-01110: data file 202: "D:\ORACLE\PRODUCT\10.2.0\ORADATA\MINOTAUR\TMP_01.DBF."
  
  How update the control file to get rid of this error?
  
  I use Windows and exit DB 10.2.0.2.
  
  Thank you very much for your help!
  
  Christian

  I think that I made a mistake of reading here.
  Looks like you have deleted a TMP file.

  You then have to join v$ tablespace with v$ tempfile in the statement.

  It's a 10 G (or higher) database?

  Try to drop the tablespace that belongs to this data file, otherwise recreate the controlfile (needs database is offline)

• How can I validate the data in the control file?

  Consider that the SQLLoader reads the data entry of the path file and loads the data in the base tables up on top of the description specified in the control file.
  First, the form is created:
  
  create table sql_loader_1 (load_time date, digital Champ_1, Champ_2 varchar2 (10))
  Example of control file:
  load_1.CTL
  
  load data
  INFILE "load_1.dat", "str"\r\n"
  insert into table sql_loader_1
  (
  load_time sysdate,
  Champ_2 position (01:10).
  Champ_1 position(11:20)
  )
  Note that positions 11 to 20 are loaded in positions 1 to 10 in Champ_2 and Champ_1. The load_time field is filled with time current (sysdate) load.
  
  Here is the data. The name of the file (load_1.dat) had been specified with the statement for infile in the control file.
  
  load_1.dat
  
  0123456789abcdefghij
  **********##########
  foo bar
  This is a very long line
  and the next one is
  short
  
  declared the Champ_1 as a numeric data type, but the input data file contains the data "Sue"(position 11:20) so the sql loader adds not the record to the database instead the record is written in the bad file. But I want to validate the data of the "(position 11:20) is digital or not." How can I post this in the control file itself? If it is not possible, how can I validate it in the database? give me a sample code to explain this

  Here are two ideas.

  Idea 1: This control file will check to see if the data to be loaded in Champ_1 contains a number (including the negative and decimal).

  load data
  infile 'load_1.dat' "str '\r\n'"
  insert into table sql_loader_1
  (
  load_time sysdate,
  field_2 position( 1:10),
  field_1 position(11:20) "decode(trim(translate(:field_1,'-0123456789.',' ')),null,:field_1,-999)"
  ) 
  

  If Champ_1 is a number or null, it is passed through, as is. If there is no numeric characters (in addition to '-'and'.') a distinct value-999 will be inserted for you allow to load the rest of the columns and easy to see the lines had data that cannot be loaded in Champ_1. This idea has its flaws (a string like "... ("will always drain the .bad file)

  Idea 2: Load the data into a staging table first (or define an external table) where all columns are VARCHAR2. Then use SQL or PL/SQL to validate data in the staging table in your process to move the data into the table with the actual data types.

• the steps of the control file multiplexing

  I am preparing for the OCP and I met the case below and I don't know which is the right answer.
  So, could help the guys take the right one and explain why?
  
  144: you want to protect your database from single point of failure by multiplexing by the control file. Your database is started using SPFILE. You must perform the following tasks
  1. stop the database instance;
  2 copy the control to the new location.
  3 configure the parameter CONTROL_FILES.
  4 restart the instance.
  Select the order in which these tasks must be completed:
  (a) 1,2,3,4
  (b) 3,2,1,4
  (c) 3,1,2,4
  (d) 2,3,1,4
  
  the answer said c) is good.
  
  Here is my explanation, please see if it's good?
  
  to ensure the consistency of the control file before copying again place, we must stop the database.
  Thus, the order is 2 must be after 1, so we got a) or c).
  to configure CONTROL_FILES, you must start the instance at least, so we can eliminate one) and we left with c).
  
  Correct me if I'm wrong.
  
  Thanks to a bouquet.

  YES, there should be two controlfiles, otherwise you get errror "Can' identity controlfile.

  My question is WHY NOT?
  These two controlfiles are the same, and instance would only need or read one of them to go further, then why not be able to mount the DB?

  It's depends on the parameter control_files you have defined in the PFILE/SPFILE file...
  multiplexing is to avoid the SPOF (single point of failure)...

  as you say, a lost controlfile... without informing you if the oracle database starts with unique controlfile... so, how can you know... If you continued if tomorrow you lost the other? While is it?

  Thank you

• Corrupt the control file

  Hello
  I try to simulate recovery scenarios. My Oracle database 11g is configured with two control files. I stopped the database and a corrupt control files by editing with random characters using a hex editor. When I started the database, everything is going like nothing happened. No warning, no errors, in Enterprise Manager the State control of the file is VALID. I opened the control file, but it is still published (so it has not been automatically replaced by the good, which is not a good thing anyway).
  Why is this happening? The system is unable to warn me if one of the control files is corrupt?
  
  Thank you

  Maybe you just edited a part that Oracle doesn't care much in normal conditions of use? Check the v$ archived_log, maybe you'll see your changes?

  Hi, Frank.

  Very nice work Helios (as usual).

  Thank you, I share just what I know thatsall

  Thank you, I learned something new today.

  The same for all users of the forum

  Normally, I clone cold backups so I don't need to manually create the controlfile.

  I see that your solution is contained in the following note;
  "Cloning of Oracle Application 11i with rapid Clone /R12 - database (9i/10 g / 11 g) using on Open Database [ID 760772.1] hot backup.

  You are correct, we mainly use this method for hot backup-Section advance clonning

  But I'm still curious to know if Nicolas is to create a clone of a hot backup or a backup to cold, and why he uses the 'ARCHIVELOG' option on his clone.

  It depends, for me I prefer to choose option NOARCHIVELOG and NORESETLOG
