• Questions about the parameters of database using a fast recovery area and the writing of two copies of archived redo logs.

  My databases are 11.2.0.3.7 Enterprise Edition. My OS is AIX 7.1.

  I am to convert databases to use individual zones of rapid recovery and have two questions about what values to assign to database settings related to archived redo logs. This example refers to a database.

  I read that if I specify

  Log_archive_dest_1 =' LOCATION = USE_DB_RECOVERY_FILE_DEST'

  the names of newspapers archived redo written in the default quick recovery area is '% t_%S_%r.dbf '.

  In the past my archived redo logs have been appointed based on the parameter

  log_archive_format='GPAIDT_archive_log_%t_%s_%r.arc'

  I think log_archive_format will be ignored for logs archived redo written in the fast recovery area.

  I am planning to write a second copy of the archived redo logs based on the parameter

  ALTER system set log_archive_dest_2 = ' LOCATION = / t07/admin/GPAIDT/arch.

  If I do this, the copy of logs placed in /t07 will be called '% t_%S_%r.dbf' or 'GPAIDT_archive_log_%t_%s_%r.arc '?

  Before my use of a fast recovery area, I used the OEM 12 c Console to specify settings of backup of database that has been deleted and archived redo logs after 1 backup. Oracle manuals say rather specify a deletion of "none" policy and allow Oracle delete newspapers in the area of fast recovery if necessary. Since I got to keep a second copy of these log files in /t07 should I keep the policy that says to delete logs after 1 backup? If I don't do that, how will they removed from /t07?

  Thank you

  If I do this, the copy of logs placed in /t07 will be called '% t_%S_%r.dbf' or 'GPAIDT_archive_log_%t_%s_%r.arc '?

  They will be "GPAIDT_archive_log_%t_%s_%r.arc". LOG_ARCHIVE_FORMAT is only ignored for directories under OMF.

  Since I got to keep a second copy of these log files in /t07 should I keep the policy that says to delete logs after 1 backup? If I don't do that, how will they removed from /t07?

  You can hold the deletion policy as it is. Oracle documentation, defining the STRATEGY of the ARCHIVELOG DELETION: "the deletion of archived newspaper policy applies to logs archive destinations, including the area of fast recovery."

• The fast recovery area cannot be used for log archiving?

  I use the version 11.0.2.3 for testing.  I read a line like below from the book of the OCP.

  If none of the LOG_ARCHIVE_DEST_n settings have been defined, then the transition

  the database in archivelog mode will define LOG_ARCHIVE_DEST_10 internally to the

  Flash zone recovery, if it has been configured.

  In my database, fast recovery already defined as below.

  SQL > show parameter db_recovery

  VALUE OF TYPE NAME

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

  db_recovery_file_dest string + FASTRECOVERY

  whole large db_recovery_file_dest_size 4248M

  So I thought that if I turn the database in log mode archive, the log_archive_dest_10 will be defined as the same value as db_recovery_dest.

  SQL > alter archivelog database;

  Database altered.

  SQL > alter database open;

  Database altered.

  SQL > show the log_archive_dest parameter

  VALUE OF TYPE NAME

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

  Log_archive_dest chain

  Log_archive_dest_1 chain

  LOG_ARCHIVE_DEST_10 string

  See archive of the database becomes, the log_archive_dest_10 always be empty.

  So is there something wrong with my understanding?

  It is quote an Oracle Press all-in-one exam guide of the I had a part in writing. Your problem is you are using 11.2.x,, but the book was written with 11.1.x. glance the relevant parameters in the docs for both versions, and you will see that the situation has changed.

  Uni Oracle validates the examinations against both versions, so avoid any question where the difference would matter, but in any case, with your attention to detail, I'm sure that tat will have no problem with the exams.

• Flash recovery Area

  Hello Oracleites,

  I have a question for you guys today.

  I have a data base of production with a size of 1 TB. We planned to RMAN backup in progress of implementation on it every night.

  We don't have the Flashback option enabled for this database. Now we intend to enable recovery flashback on this database option.

  Could you please help in finalizing the figures on how much Flashback recovery area, we need to get this implemented.

  Appreciate your help.

  Thank you

  Martine Sra

  Hey Garry Sra,

  Well, you're the only one who could answer this answer, but what to look at is:

  1. How much redo is generated by the database if it is enabled in archivelog mode. If it isn't, then you must analyze married how your online newspapers, can be restored for a day;
  2. What will be your SLA regarding archivelogs in the disc, the archivelogs backup routine and the retention time of flashback (flashback is activated)?
  3. After that, you can make sure how much area recovery Flashback database will need.

  Kind regards.

  following steps should be ok
  (1) create pfile from spfile;
  (2) remove the unnecessary params
  (3) configure log_archive_dest_1
  Note: do not remove the db_recovery_file_dest, db_recovery_file_dest_size, and parameters. they may be required at another time
  (4) stop and start your database using this new pfile
  (5) check if the archives are in one place
  (6) create spfile and bounce database to ensure that it uses spfile

  Please try all the steps test env first and go ahead in the event of success, to production

• management of the Windows flash recovery area

  Hi experts,
  
  We use oracle 10G R2, enterprise edition on windows 2003 Advanced Server...
  
  We have a size 20 GB database with archive log mode and archiving destination specified to Flash the recovery area. We don't use RMAN as a backup strategy. and are flash recovery size is set to 5 GB. as it is an OLTP system, it generates a lot of log archiving in the flash recovery area, order of frequent newspaper with the redo log file size is 100 MB.
  
  I would like to know, how can I manage the flash recovery area, if I do not use RMAN to specify archivelog retention policy? How can I specify that oracle should keep log archive files to flash recovery are for 5 days? as we know that oracle won't remove any permanent file at least flash recovery area that it is obsolete, and database may hang if there is space in recovery is full... I can take the log backup archive to another disk, but is it possible to say oracle keeps log archiving for 5 days and remove them to recover space in case of disk space full for the flash area?
  
  
  or if I put the retention using RMAN policy, it will take effect for maintain the retention policy and remove the log archiving obsolete in the area of flash recovery after 5 days, even if I do not use RMAN to back up my database?
  
  any suggestions would be much appreciated
  
  Thanks and greetings
  VD

  Vikrant dixit says:
  We use import export for backup of database (political company it's not mine)

  Then suggest or explain this imp/exp is not any type of backup. It's a data dump. And it won't save disaster. There will be data loss. If it's good to society, then it's ok.
  And then perhaps it is not necessary to keep the database in log mode archive if exp/imp is used.

  .. .and archive logs are generated and not backed up yet... that's why I asked this question here how manage space flash in a future close if space is complete in the same...

  Then, you must implement the log backup archive and deletion with rman. And if already happens with rman, then why not go further and use rman for full database backups.

  What you need to do:
  1 understand how often do you need to archive backup logs
  2. When you save them (tape, disk)
  3. making scripts to archive log backup or remove and obsolete backup deletion.
  It may be just a script
  delete any backup archivelog entry;
  remove obsolete;

  Look here for more details on orders:

• Re: Toshiba Recovery Media Creator - no HDD Recovery area

  Hi friends, I bought a new Toshiba Kirabook PSU8SA-00V00U, a few months ago. I wanted to create emergency recovery disks, but whenever I start Toshiba Recovery Media Creator, it comes with a message that HARD drive recovery area undetected.

  Then I tried running the recovery environment by pressing 0 at the beginning upward.
  It comes with a blue screen saying that can not load from the recovery partition.

  I checked with Paragon Hard Disk Partition Manager software that the recovery drive is available.

  How do I make a recovery media or connect this HDD in system recovery so that Toshiba Recovery Media Creator detects the recovery disk and made recovery media. If in the future, if I want to reset the PC to factory settings, it will be even coming up with a blue screen saying that it can not load the recovery environment.

  Any help will be appreciated!

  Hello

  Fact is that the installation of image recovery or recovery media creation works if the machine has only factory settings. In other words, everything must be in original condition without any changes. With the changes I mean, original OS must be installed and the structure of the partitions of HARD drive should not be changed.

  If you try to change HARD drive partitions original structure the system in general, or Toshiba recovery media creator, will be confused and will not be able to find what we call markers which provide information on the exact location on the HARD disk where the recovery image is placed or registered.

  Did you do something that might be responsible for this situation?

• No HDD Recovery area

  Hello

  Im not getting that error at the launch of the "no HDD Recovery area" software is not to delete the recovery partitions I didn't touch... I tried to restart and hold down the 0 key it did not work, I used f8 but toshiba recovery did not work, he asked me to choose a restore but nothing was on the list and when clicking then nothing happens.

  PS: I can still see in the Device Manager, it is not removed and its healthy state on the recovery partition.
  Help, please

  Thank you
  Elyas

  Can you tell us first what model of phone you have?

  The fact is that preinstalled with no data recovery software. I think you you don't l l remove anything, but if you got your laptop by using the wrong option.

  Have you used the HARD drive recovery option in the past?
  You created the recovery DVDs?

• Portege Z830 - "No. HDD Recovery Area" more

  Hello

  Today, I wanted to do recovery USB stick with Toshiba Recovery Media Creator. To this end, I bought 16 GB 3 / 10 MB/key Verbatim s.

  I tried several times without success. Whenever I tried a Toshiba Recovery Media Creator noticed the error: * 040E2D-00-00000000 error code *... or nothing happened. I put in another new 16 GB USB 3 / 10 MB/s and the same thing happened.

  After that, I tried the third USB I had - Corsair 32 GB USB 3.0. And it worked: I did successfully recovery USB key, but this key that I use for other things...

  Then I continued with 16 GB Verbatim key. After a few tests more Toshiba Recovery Media Creator noticed "* no HDD Recovery area" * and after that I could do nothing. ".

  * What should I do now? * I think I did not ' do anything bad, just tried data recovery in the key of 16 GB. The only thing I did is this button formats formatting (with disk management... because after all the computers of the trial has not yet identified key...).

  Thank you for your advice in advance.

  Tomaz

  Hello

  It is not easy to say what the problem is here. The fact is that recovery image is marked with specific markers that can be found in Toshiba Recovery Media Creator. When the creator find these markers application starts correctly and recovery media can be created.
  I can't tell what the problem is here.
  > After that, I tried the third USB I had - Corsair 32 GB USB 3.0. And it worked: I did successfully recovery USB key, but this key that I use for other things...
  This sentence confused me. You have successfully recovery USB key created or not?

  By the way: try to start the HARD drive recovery facility to see if the same message again.
  Please post comments.

• CAN bus off fast recovery and recovery slow modes

  Where you see the terms "broad recovery fast bus" and "slow bus off recovery". As far as I know, the spec CAN define only a single bus out of recovery.

• "BACKUP RECOVERY AREA DESTINATION" and several channels

  Hello

  I'm on 11 GR 2.

  I use the feature OF "< specific directory >" DESTINATION of the order of CONSERVATION RECOVERY AREA

  staging the backup, my CRF, a few hours earlier. I wish

  1 / to be able to compress this backup in my <>directory (my regular backup to the FRA is * not *)

  Tablet!) ;

  2 / and to parallelize this staging.

  Here http://docs.oracle.com/cd/E11882_01/backup.112/e10643/rcmsubcl018.htm#CIHBDIGE

  at some point, they say that "this paragraph, when it is used with the BACKUP RECOVERY AREA , allows.

  allowing you to designate a drive as the location channel': How do you understand this? Do you want that he woud allow you

  to specify things like

  Run {}

  ALLOCATE CHANNEL c1 DEVICE TYPE disk FORMAT ' / usr/oracle/FRAstaging ' MAXPIECESIZE 100 G;

  TYPE of DEVICE of c2 ALLOCATE CHANNEL FORMAT drive "/ usr/oracle/FRAstaging ' MAXPIECESIZE 100 G;

  recovery zone backup destination c1;

  recovery zone backup destination c2;

  }

  or should I rather do something like:

  Run {}

  TYPE of DEVICE of c1 ALLOCATE CHANNEL MAXPIECESIZE 100 G drive.

  TYPE of DEVICE of c2 ALLOCATE CHANNEL MAXPIECESIZE 100 G drive.

  recovery zone backup destination "/ usr/oracle/FRAstaging";

  TYPE of DEVICE of c2 ALLOCATE CHANNEL MAXPIECESIZE 100 G drive.

  backup recovery area;

  }

  Has anyone tried to stage his FRA on some directory of operating system or backup tape?

  Which of the above syntax is correct? Any idea?

  Thank you very much!

  Kind regards

  SEB

  Hello

  The correct syntax is the second. Take a look:

  RMAN> run {
  2>  ALLOCATE CHANNEL c1 DEVICE TYPE disk MAXPIECESIZE 1G;
  3>  ALLOCATE CHANNEL c2 DEVICE TYPE disk MAXPIECESIZE 1G;
  4>  backup recovery area to destination '/u04/temp';
  5>}
  
  allocated channel: c1
  channel c1: SID=453 device type=DISK
  
  allocated channel: c2
  channel c2: SID=36 device type=DISK
  
  Starting backup at 09-OCT-14
  specification does not match any datafile copy in the repository
  channel c1: starting compressed archived log backup set
  channel c1: specifying archived log(s) in backup set
  ......
  

  The first syntax is bad because you can't say "to destination c1. The destination must be a path.

  The third argument is false because ' RMAN-06603: DESTINATION option must be specified with the AREA of RECOVERY, RECOVERY of FILES or DB_RECOVERY_FILE_DEST on the disk device.
