Backup control files on the eve of the database

• Retrieve by using the backup control file

  Hello

  I was reading a book called Pro Oracle Database Administration by Darl Kuhn. There, under the theme of "The valuation of the loss of all control files", noted that all data files and control files are restored from a backup, because if we do not restore the data files the RCS in control files would be lower than the data in these scenarios files. Since online redo logs and archived newspapers is applied to the data files to roll forward in a current consistent state and does not roll forward to a control file.

  It is then mentioned to use 'recover the database by using the backup control file' then apply the logs (archive and redo if necessary).

  However I personally tested this script in a test environment and to bring all the backup control file could issue the same command as above and recover the database.

  My question is I know again and archives are applied only to the data files. So how does the control file are synchronized back when we do not restore the backup data files.

  Thank you

  If we do not restore the data files, the RCS in control files would be lower than the data files. Since online redo logs and archived newspapers is applied to the data files to roll forward in a current consistent state and does not roll forward to a control file.

  It would be incorrect you have determined. You can only restore the control files. You can manually create a control file and always do the restore.

  My question is I know again and archives are applied only to the data files. So how does the control file are synchronized back when we do not restore the backup data files.

  The control file is updated as well.

  See you soon,.

• Why open DB with RESETLOGS option after either complete or CAMILLE with a backup control file?

  Hi all

  I'm newbie DBA and totally confused when reading about the recovery.

  Why open DB with RESETLOGS option after either complete or CAMILLE with a backup control file?

  Using while will happen after we open DB using resetlogs in above mentioned mode of recovery.. .apart from resetting the log sequence 1?

  Kind regards

  Hi Ritu,

  Google is a very rich source of information...

  I found this article in Hemant which I suppose is very informative for you... Read everything including the comments!

• hot backup control file?

  I wonder and wants to know... we can put hot backup control file... If so, then isn't the content of the controlfile changed after backup?

  alter database backup controlfile to 'd:\backups\cntrlfilebackup.dbf reuse';
  alter database backup controlfile to trace as 'd:\backups\cntrlfile_trace.txt reuse';

• Download any file in the database column

  Hi all

  Is it possible that I can download any file in a column of data?

  I use oracle forms 6i and oracle database 10g.

  Kind regards

  Dear Sir

  You can select the built-in file using GET_FILE_NAME. And then copy the file into the database using HOST Directory integrated (using the CMD). After you copy the file in the database directory, you can call the procedure of database to update the database file.

• .txt or CSV file to the database

  Hi-

  I have a file of text generated by a Pulse Oximeter, what I want is, as the system is receiving the file (CSV .txt) he automaticly walked into a MySql or SQL Server database and generates an SMS message. Thank you

  Concerning

  Tayyab Hussain

  Web services involve using sychronous communication. However, the use case you describe means that asynchronous, the so-called fire-and-forget, communication is better suited to your needs.

  For example, with sychronous communication, the system ignores the exact moment where in a TXT or CSV file will come. Also, when the Treaty system a file, all the other treatments waits until the system ends. This can cause synchronization problems if multiple files enter the system in quick succession.

  ColdFusion is an asynchronous solution that fits the requirements of your use case. The following methods will allow you to receive the file to automatically enter data and generate an SMS message. Use the DirectoryWatcher gateway in ColdFusion to monitor the directory in which the TXT or CSV files are deleted and events of ColdFusion SMS gateway to send SMS messages.

  Whenever a third party files a file in the directory, an event is triggered, setting the DirectoryWatcher in action. Set up a query to the onAdd of listener of the DirectoryWatcher CFC method to store the file in the database.  Following the request, use the sendGatewayMessage method to send the SMS message.

  You don't have to restore the full database. You just need to restore the backup controlfile and restore the database.
  The steps you mentioned are good restore the controlfile. After recovery, you must open the database in resetlogs.

  Also, you can take a look at this http://neeraj-dba.blogspot.com/2011/04/loss-of-control-file-in-various.html

• We can to restore the content of a game without the backup control file?

  Hello
  
  I went in earlier today, a situation when someone (it wasn't me this time!):
  (1) a to back up a database and its archivelogs, in a compressed backup sets;
  (2) pushed the files to another server and
  (3) deleted everything on the server source, including ALL control files and control files.
  
  As he tried to recover the control file was missing and asked for help... I worked around the issue by using the snapshot controlfile he had forgotten (lucky me!)
  
  Now I can not remove from my mind the idea that I won't be so lucky the next time... I wonder if there is another way to work around this problem?
  
  Does anyone have an idea how to restore the contents of a backupset when we lack ALL control files and their backups? I tried to save the backup in the controlfile to a different database, but it does not work. I didn't find anyway to recreate a controlfile with a specific dbid without data files (and those who are in the backupset...).
  
  Any other idea? Best regards
  
  Gregory

  Hi arkzoyd,
  Is the only way to restore data from a backup set files using rman an instance and a controlfile so the answer is no.

• Incompatible control file and the data after the backup files

  The company that I work has servers where some components are new more, so have a backup in the event of hardware failure. If we intend to do some clones of 1:1 of the current servers to change them in case of emergency. As most of the necessary data is not volatile and we reset stuff in any case, there is no need of replicaton, replace an old version of the database works very well. Now we could not easily get substitutes for our old material, so we had to set up new machines. And that's where my trouble starts, because now I had to actually set up the system and the database rather than do a simple copy of byte to byte. I'm mainly a programmer, using Oracle of 'other' side, but as our DBA is yet to come and the work must be done now...
  
  So I did some reasearch and decided to do a normal backup of the cold. I have dumped the controlfile, copied data and configuration files to the new server and read the prompt SQL (no mistake there) control file. After some initial hiccups with the system (memory, etc.), I was finally about to start the database, only to get an error ORA-01190 ("1 database or control file is from before the last RESETLOGS").
  
  I guess I did is a bad thing when you restart the database (used the wrong part of the control file) or when the copy of the data. The original data have split two readers for simplicity and logical, I copied their entire contents. So maybe I don't not copied to little but too?
  
  As I said in the introductory paragraph, I'm not a DBA, but I'm willing to learn and listen. I don't expect a complete solution, but some guidelines when to look and what to avoid. Any help on this would be appreciated.

  Currently, there are some points need clarification,

  1. you don't need to re-create the control file, if you have a clean shutdown database and copied all the files at the same time (data files, control files etc.)

  2. If you stop DB, copied files of data but do not copy the control at shutdown file, you must re-create the control file.

  3. the error ORA-19909 suggested you resetlog prior to recovery.

  ORA-19909: string data file belongs to an orphan incarnation
  Cause: The data file specified has been restored from a backup that was taken during a period of time that has already been abandoned by a resetlogs operation or Oracle cannot identify what incarnation of database file belongs. The alert log contains more information.
  Action: Restore a backup of this file that belongs to the current or a previous incarnation of the database. If you use RMAN to restore, RMAN automatically selects a good backup.

  4. it would be better that again follow you from scratch the article.

  for example,.

  Copy the files you did copy over the data base to the bottom of the old server,
  modify the control file creation script

  RECOVER DATABASE USING BACKUP CONTROLFILE;
  ALTER DATABASE OPEN RESETLOGS;

• 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;

• File system backup as well as the database

  Hello, people dear oracle,
  
  Is it possible to make the backup hot to the application (files) as well as the database layer?
  
  Best practices in this regard?
  
  I know it does not seem serious and it is not an urgent issue, but I would appreciate if someone can find more information about this.
  
  Thank you.

  Yes it is possible (assuming that you are on Linux/Unix). However, you may lose some of the files that are generated at the time wherever you take the backup of the node (s) application layer, as (files of applications simultaneous/out of the newspaper, newspapers of CM... etc).

  Thank you

• Backup of files on the computer

  Hello

  I'm trying to implement a system with Adobe and because I'll end up with a large number of files, I wonder... Is it possible to save files in the cloud on my computer? I would like to be able to import the files and folders, as it is (not one) to my computer so I can delete them in the app on my ipad.

  Thanks for your help!

  Mary

  Hi MPguillot,

  If you want to save the PDF files you can use free storage space of 5 GB on Adobe Document cloud https://cloud.acrobat.com/recent using Adobe ID, else if you have too many other file formats, you can use services like google or dropbox cloud.

  Kind regards
