  The use of the files managed by Oracle
  Internally, Oracle uses standard file system interfaces to create and delete files if necessary for the following data structures:

  * Tablespaces
  * Online redo logs
  * Control of files

  Through initialization parameters, you specify the directory of file system to use for a particular file type.
  EXAMPLE:
  The following parameters are included in the initialization parameter file:

  DB_CREATE_FILE_DEST = ' / u01/oradata/sample.
  DB_CREATE_ONLINE_LOG_DEST_1 = "/ u02/oradata/sample.
  DB_CREATE_ONLINE_LOG_DEST_2 = ' / u03/oradata/sample.

  The following statement is issued at the SQL prompt:

  SQL > CREATE a DATABASE sample.
  SQL > CREATE TABLESPACE tbs_2 DATAFILE SIZE 400 M;
  SQL > CREATE UNDO TABLESPACE undotbs_1;

  No, it won't, it will transfer personal files and settings. You will have to reinstall your applications from the original installation files or install CDs and DVDs.

  Can someone give me the better, easier and faster method available. At least give me a step by step procedure for this task.

  If you really want to move your applications to the Vista computer, you will need to buy a commercial programs such as Laplink PC Mover that will allow you to move your programs:

• On the use of the data file

  Hi all

  Last week I was simulating a crash of my database (Oracle 11.2.0.3, last group of patches) due to data files missing. So, I just removed the data file where my web application stores the data to see what's going to happen. But nothing happened, demand is rising and running and I was able to create new items in the user interface and save them. Normally, all these data are stored in oracle.

  After that I created a few articles, I bounced the database. Then I restored and retrieved the data file with RMAN. All items I created after the deletion of the data file were there.

  I would like to know, in which oracle order would write the DML commited to for recovery logs and the data file, so that I can explain the behavior of the application. I was wondering how the commited changes after deletion of the data file have been preserved even after the restoration of the data since the last backup RMAN file.

  Thanks for any input.

  Best regards

  Coby.

  every time that you agree to any transaction that the LGWR writes that transforms redo log buffer to restore the log file. When saturates redolog files then it launches checkpoint and writing each thin to the log file archive.

  DBWR writes data to the buffer cache of datafile only if it doesnot have free tampons with him.

  In your case, what could have happened is when you deleted the data file and made changes in the database. He could not write these changes to the data file and made the entery in the redo log file.

  so, after you have to bounce the database and restore the database and retrieve using the archiving log. you'd get output like media recovery complete and all the changes made to the database once you have deleted the data file, all the changes has returned to recovery.

  Is your database in archivelog mode? If so,.

  find the number of the data file (for the use of data instead of the name file number):

  SQL> select file#,name from v$datafile;
  

  Assume that n is the number of folder of the data file. Start rman and try to get it back:

  RMAN> RECOVER DATAFILE n;
  

  If it shows that you want to restore, restore the data file and recover:

  RMAN> RESTORE DATAFILE n;
  RMAN> RECOVER DATAFILE n;
  

  go online:

  ALTER DATABASE DATAFILE n ONLINE;

• How to get the Date, month, year of the DateTimePicker

  Hi, I am using the DateTimePicker.

  There are several question about this command:

  1. how to get the Date, month and year?

  -With the help of myDateTime.value, I get this string ' Wed May 08 14:45 ICT 2013 '-> I have to manually analyze this? Because I need in format yyyy/mm/dd. Or can set the format of dateTimePicker.value?

  2 format on dateTimePicker self (on the user interface) is d/m/YY, I can't change to another format?

  Thank you

  dateTimePicker.value return a QDateTime not a string.

  See more:

  https://developer.BlackBerry.com/Cascades/reference/QDateTime.html#date

  https://developer.BlackBerry.com/Cascades/reference/QDate.html

  You can get

  day = dateTimePicker.value.date().day()
  month = dateTimePicker.value.date().month()
  year= dateTimePicker.value.date().year()
  dateYYYYMMDD = dateTimePicker.value.date().toString(Qt::ISODate)
  dateYYYYMMDD2 = dateTimePicker.value.date().toString("YYYY/MM/DD")
  dateYYYYMMDD3 = dateTimePicker.value.toString("YYYY/MM/DD")
  

• A SCN for the entire database and the different SNA for the data files?

  DB Version: 11 g
  
  I always thought that there is a unique SCN for the database as a whole.
  A quote from the link below as
  When a control point is completed, Oracle stores the RCS individually in the control for each data file file
  http://www.dbapool.com/articles/1029200701.html
  
  
  What does that mean? There is a SNA for the entire database, and there are individual SCN for each data files?

  Well, unfortunately, the article says more bad than good things. Or if I can't call them wrong, they are rather confusing and rather than clear things for the reader, its making them appear to look more confused.

  First things, YVERT is used for read consistency (CR) mechanism and the backbone of the notion of Multiversioning. The control point is the mechanism to help that recovery is decided. Contrary to what said article, not any kind of checkpoints update both the data file and the control file, and also, there is not a type of them as well. In addition, the article says that the LAST_CHECKPOOINT is set to NULL, while its actually set to the infinity since it is not possible to detect the moment when the database is opened, that the last issue of control over the file would be. In the case of complete control point, this number is saved and is also associated with the toa Controlfile own database leader at the next startup. If this is not the case, there is an inconsistency in the stop_checkpoint of the data file and the stop_checkpoint reocrded in the control file, leading to a recovery of the instance.

  There are several types of control points. Similarly, there are several types of SNA as well. Without going into the details of these, IMO, the article simply means that when the control point write over a file passes, oracle updates the file checkpoint on it and this is recorded in the Controlifle. as well.

• Prepare disks for ASM (data files and FRA)

  I intend to place data files on a disc 1 (sd1) and disk2 (PSD) when the backup of files (FRA) on disk3 (SDC). Here's how I'd do:
  
  For data files
  Disk1 is divided into a single primary partition (with native Linux what ID 83 not formatted system)
  Disk2 is also divided into a single primary partition (with native Linux ID 83 system not formatted)
  
  oracleasm createdisk vol1/dev/sda1
  oracleasm createdisk vol2/dev/sdb1
  
  CREATE DISKGROUP DATA EXTERNAL vol1, vol2 REDUNDANCY;
  
  
  For backup FRA
  
  Disk3 is partitioned into four primary partitions: / Boot (ext3), / (ext3), swap (swap) and /u01 (ext3)
  
  The FRA will be put under the/U01 and then attend the ASM:
  
  oracleasm vol3/dev/sdc4 createdisk
  CREATE DISKGROUP DATA EXTERNAL vol3 REDUNDANCY;
  
  Now, the problem. (1) the/U01 has already be formatted in ext3; (2) Oracle (DBMS) software will also be place under/U01
  
  It will be a problem?
  
  
  Otherwise, I can put FRA on the same drive as the data files, i.e. on disk1 and disk2. In this case, I need to partition the disk 1 in two primary parititions sda1 and sda2 (native Linux system ID 83 not formatted), one for data files and another for FRA (do the same for disk2). The downside is that the data file and the file recovery will be on the same hard drive.
  
  
  Please offer some suggestions.
  
  
  Thank you
  
  Scott
  
  PS: in the environment of production, all the disc 1, 2 and 3 will be on hardware RAID 1.

  RAID 1 will protect you only a device failure. It won't protect you partition, the file damage system or user errors; It will be in the image of the errors and problems like any other data.

  So what happens if you delete by mistake / U01 or some other accident happens and you loose that partition? With your current setup, you will lose everything and will not be able to restore or recover the database. Put tablespaces FRA and DB on the same physical device is certainly a very bad idea, whether or not it is a RAID.

  ASM is not a software RAID 1 mirror. It ensures redundancy of data based on file extensions and knows about files of Oracle database, which is a very good thing. You probably do not want to specify 'external redundancy.

  In a production system, you'll certainly want to mux the critical data and to store the DB controlfiles, redo logs and finally archivelogs on media separate physically in order to avoid the single point of failures wherever possible. You can use partitions and volumes in ASM, but they should be separate physical drives, otherwise you will bypass the ASM data redundancy. You must also have a solid strategy for RMAN backup. The FRA is supposed to store backupsets RMAN, copies of the image, the important archivelogs and multiplexes of the copies of the database files and should therefore always on a separate physical disk.

  Unless you simply play, I strongly suggest that review you your current configuration.

• datafiles and redo logs on the same drive

  Hi guys,.

  http://docs.Oracle.com/CD/E11882_01/server.112/e25494/onlineredo001.htm
  >
  Database only Oracle uses redo log files at the same time to store redo records written since the restore log buffer by progression. Log roll forward LGWR is preparing actively to is called the log during recovery.
  >
  
  If the process flow, I got after reading the chapters is
  
  When LGWR fills a log file of redo (roll forward records) then there will be a log switch + control points where writing for data blocks occur. There seems to be a flow series rather than a simultaneous sort of flow. So I don't really understand it when he speaks of contention will take place when records of data and files written redo which is the redo log file are on the same disks.
  
  Just to confirm with you guys, whenever there is a switch of newspaper one point of control occurs too right.
  http://docs.Oracle.com/CD/E11882_01/server.112/e25494/onlineredo002.htm? You can search checkpoint to access the section she made mention of this documentation.

  Think about this:

  Restore means to keep the information around in case you need to re-do (recovery or standby mode, i.e. the continuous collection). Updates as you do in a broad sense will be so potentially being twice, once for the data files and once to do it again. I'm sure you understand that the data is written in memory, and then later to the data by the writer of the db files, while there could be many more group of writing data, or they may even be long delayed. In addition, the data files are read at random, so you can't really think again in series compared to the data. Do it again is series, archiving is set, but the data is random, and random how depends on how your system is used.

  So that means all the type of reads and writes per redo and archive is fundamentally different from data and cancel. In the first case, you want to be able to breath out as I/O that you can, for the latter, you want to be able to randomly reading or writing at different times, with Oracle being smart enough to do a bit of it in memory and optimistic enough to make assumptions on when to do things and quite lazy for not doing everything right. Roll forward is critical.

  A while ago, someone pointed out that the e/s modern buffered in memory, do not really worry about this, because all the work required to set up and maintain it after spending records, fees are not much better than striping and mirroring everything (you can google SAMI). This is true to a point, and we can debate endlessly about RAID types and their effects on performance and how their buffering makes [url http://www.baarf.com/] useless BAARF. But the real debate is, where is the point that you should use separate to redo and data devices? In the real world, we often receive a standard hardware configuration, which works very well until it's not. A disk or controller will puff in a RAID-5 can happen "is not" real quick.

  You should probably take two thoughts:

  The docs are pretty General, and some old tips do not apply, may have transformed into myth or perhaps too general to be meaningful.

  There is always something in the db, and the more things underway, less you can make generalizations about the serialization.
