Doubt of free space area of fast recovery

Similar Questions

• 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."

• Fast recovery area size

  Oracle 11g r2 on Linux.

  The system configuration:

  + DATA (ASM diskgroup data multiplexed logs file online and control files of 300 GBtotal capacity)

  FRA (file system like ext3 on the ability of oradata/u01/oradata of separate drive of 300 GB of cooked)

  Now create the database with the dbca Wizard:

  On the homescreen "Multiplex Redo Logs and control files", I specified oradata/u01/oradata (located on the drive of FRA) and another copy to the location by default of the + DATA diskgroup.

  On the screen of the fast recovery area:

  Fast recovery area: / u01/oradata
  Fast recovery area size: 4122 M bytes
  Enable Archiving-> Archive Log Destinations: / u01/oradata

  
  

  This ASSESSMENT will take the following files to run:

  1 multiplexed online redo logs and control files

  2 archived redo logs

  3 game data files backup (full and incremental)

  Given the fact the + storage capacity is 300 GB and the FRA will hold all of the above files, can I change the default 4122 MB to a number close to the 300 GB, such as M 290000 bytes?  or any other number (less than the size of the FRA disc).

  Thank you

  Scott

  You have specified/u01/oradata as the location of your fast recovery area. And then you have specified/u01/oradata as the location of the error log archive and multiplexes onlne logfiles. This will cause terrible confusion. Just because they are in the same path does not mean that they are the same thing. If you did as you described, you do not use the FRA at all. You will need to ask the IS_RECOVERY_DEST_FILE of the views column to check if a file is actually in the FRA, rather than just happening to be in the same directory of file system.

• Run Disk Defragmenter has released more than 30 GB of free space!

  I'm not used to run Disk Defragmenter Windows very often, but in recent weeks I have been through the very large import of my cd collection process on iTunes. My 'C' drive has a capacity of 222GB and I was at 9.68 GB of free space. I ran WDD but after 18 hours, he had still not finished! So I decided to cancel defragmentation, and after checking my 'C' drive, I found to my great astonishment that I now had 42.8 GB of free space! Then, I downloaded the DiskDefrag Auslogics free and running. She performed in a few minutes and showed the Windows defragmentation had done most of the work but for some reason any had not finished. Anyone know why?

  I have decided to disabled Windows Defrag and will use in the future, the Auslogics version he gives information about the status of the defragmentation and seems to be much more effective and faster.

  However, I am very surprised by the amount of free space that freed the defragmentation process. I searched on various forums of pc and other posters have said the complete opposite to my own experience. The common consensus seems to be that defraging reduces the amount of free space on a drive rather than increase it!

  There also seems to be a difference of opinion on the amount of free space should be left on a hard drive to allow the computer to function effectively. I was a little more than 4% before I defragmented but I saw messages advising that we should let betweeen 10% and up to 50% (which seems to me to be silly!)

  I would be grateful for any help anyone can give me, in particular, why the defragmentation released (in my case) as much free space.

  A common mistake in logic. You assume that two things are related, because they are close in time.

  Defrag does not change the amount of disk space. It only increases or decreases the free space or used.

  Windows defragmentation runs every three days and optimizes the program and load the system boot. This is not controllable. It is also not a defragmentation of data file.

  Using another Defragmenter will fight with Windows.

  NTFS (and FAT32) resist fragmentation. Most fragmented files are log files and will fragment 1 second after defragmentation.

  Windows only writes files where there are a lot of space to write prevention of fragmentation. Do not fragment the files that do not change. Disk cache makes the fragmentation irrelevent.

  Any recommendation on the free space are based on the best estimate on the way an average person uses a computer. Lack of free space does not work computer until it has zero. However, most people like to save their work and some Windows watchdog is going spastic, just before that you can't do anything.

  As to why you have noticed a change in the use of the disc.

  1. system restore - this could be it.

  2 disk Cleanup - it will take place in itself is space is extremely low

  3 log files are created, deleted, written, etc.

  4. Windows automatically repairs physical disk errors. If defrag was having problems, you can check there is no car repair files.

  It's a way see what may have disk operations occurred.

  Start - All Programs - Accessories - right on command prompt and choose run as administrator. Type (or copy and paste by clicking in the command prompt window and choose Paste).

   

  change c:\bootex.log

   

  What is this file exist with something in it?

   

  The following commands query the event logs.

   

  To start verification by using the name of the source for any version of Windows (because it varies).

   

  WMIC /append:"%userprofile%\desktop\DiskEvents.html" PATH Win32_NTLogEvent where (sourcename = "Autocheck" or sourcename = 'Winlogon' or sourcename = "WinInit") get format:HForm

   

  To run chkdsk in Windows.

   

  WMIC /append:"%userprofile%\desktop\DiskEvents.html" PATH Win32_NTLogEvent where (sourcename = "Chkdsk") to / format: HForm

   

  For warnings about disk problems detected during normal operations and automatic repairs by Windows at the time where the problems were discovered.

• I 4.41 MB of free space on recovery (d) 14.6 GB, what can I do to get more space?

  Hello! When I bought CONNECT, the technician I spoke with told me I was 4.41 MB of free space on recovery (d) 14.6 GB. What can I do to get more space? I need help, please!

  Hello

  ·        What operating system is installed on your computer?

  ·        What is the brand and model of the system that you are using?

  ·        It is specific to a particular Web site?

  As it is the recovery drive partitioned pre, and it was created by the manufacturer to expand you would need to get in shape. I suggest you to contact the manufacturer for support. You should not save files or data on the recovery partition as it is only meant to recover the operating system if something happening time.

• Message says low disk space on recovery D, free space by deleting files to support...

  Original title: get the message on the recovery of free space low disk space by deleting files bear D. I deleted by using disk cleanup, but I still get the same message?

  I got disk spave low recovery D ask me to use Disk Cleanup to delete the old files. I deleted many files and none using programs and I still get the same message. How can I clear this problem? I'm using Vista Home premium.

  Hello

  In NO case should remove anything from the recovery partition.

  Your recovery Partition was photographed on your hard drive during the production of your computer by the manufacturer for all of these reasons.

  1. to reinstall Vista from in the case of a failure of the system, based on individuals or the keys at startup.

  F10 or Alt + F10 or F11 are a couple of different manufacturers use sequences.

  You will need to ask your manufacturer for proper sequence.

  2. to make the recovery disks on if your drive hard breaks down, so that you can then reinstall the operating system on a new hard drive.

  Also ask them how to make records.

  Your D: Recovery Drive is should not be used for backups, defragmented, etc..

  There are backups on an external hard drive.

  To resolve the problems that have arisen with the recovery D: Partition, you will need to contact the manufacturer of your computer to remove all that has been added to it.

  See you soon.

• How can I increase my recovery drive (d). It is fixed to 15 GB and I have tons of free space and want to bring to about 40-50 GB

  After only 1 or 2 backups, it overflows. I want to open more space and I see a few large files, but I don't want to delete them without knowing what they are.

  NT ATLEE/SYSTEM IS one of them to 12.5 GB. It doesn't seem likely that it would be to delete. I have no junk left to remover or.

  I recently got burping on IE. I recorded everything and can reinstall the whole system, drivers, updates, etc.

  Before that, I would like to know how to enlarge my recovery in order to have several bakups to restore later if necessary, without having to go through everything.

  Sometimes I save a backup elsewhere for easier restoration also.

  Using Win 7, IE 7 again, on a not to mention dell POS.

  Really, I hesitate to use the most recent EI, until the BS is that they are ALWAYS overcome. Maybe it's time to IE8? Laughing out loud

  In any case, all I really want is to expand my recovery disk. Tons of free space on hard drive. 844 franco departure 916 GB.

  I seem to be close, but can't get on top. I have taught myself since military-electronic learning computers and

  1 semester electronic engineering in College 20 years ago. Just bought 1, turned on and started fishing around end 90. All I really need to understand is interface software and programming stuff.

  This seems to be a basic enough scheduling feature to be able to do it myself.

  Thanks in advance, Greg

• Recovery of free space Compellent

  Hi guys, I installed a new Dell SCv2020 Compellent storage with vSphere U3b 5.5 for an existing customer

  I have a deep knowledge of Dell PowerVault storage, but I'm new with Dell Compellent. I read that the snapshots for backups or running Storage vMotion can affect free space on the end due to the native LUN provisioning storage: communities.vmware.com/.../436628; TSTART = 0

  The suggestion is run or plan the command "esxcli storage vmfs unmap-l MyDatastore" which calls the primitive SCSI UNMAP manually

  I tested a Storage vMotion and indeed space on the source LUN are assigned until this only manually 'no '. I have not yet tested how instant backup affect free space on the storage because I've not yet migrated any VM on the new infrastructure (by the way I use v8 of Veeam Backup who insist a lot about VMware snapshots)

  Anyone here can share ideas and comments? Thanks a lot guys

  Marco

  You are on point, use the tool unmap to reclaim space on the LUN. Compellent thin provisions at the end back and depending on your environment, you should probably be thin provisioning your LUN on the end of VMware. To the wire when you remove VMware servers and vmotion of data store to data store space, will not be recovered on Compellent b/c, that storage is ignorant because data are only is more used. The "fix" for what there is complete integration between VMware and Dell is to run that unmap tool.

  What started doing every quarter or so is to run the tool unmap on all LUNS that are thin and put into service (in our environment all volumes). I tested unmap several times and I had no problems with running the tool while the servers are running on this volume. I would say that the tool running on a server that does not have a lot of load work because the CPU spike during unmap (datastore readings will boost as well).

  Regarding backups and snapshots, I have no problems with the space about those. Replays freeze blocks of reference data, but once this review has expired the space is recovered. Regarding backups depends on what you use for backups - we use CommVault who will take a glance of the LUN, copy the data off power then release the tension (so for a short period of time, he didn't there ate during the backup space, but it takes a few minutes to copy the data).

• How can I determine the size of the fast recovery area?

  ORACLE DB 12 c EE Windows:

  All the rules are available to calculate the size of the fast recovery area?

  See the ORACLE 12 c documentation:

  http://docs.Oracle.com/database/121/BRADV/rcmconfb.htm#BRADV89425

  Disk quota =

  A copy of database size +.

  Size of an incremental backup.

  Size (n + 1) days of archived redo logs.

  Size (y + 1) days of archived foreign newspapers of recovery (for logical standby) +.

  Size of the control file.

  Size of the online redo log member * number of newspaper groups.

  Size (based on the value DB_FLASHBACK_RETENTION_TARGET) flashback logs.

• 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.

• Windos said my HD 52 GB of free space, but my files are bigger!

  Hello:

  I use Windows 7-64 bit SP1.
  In my c: drive properties it says I used GB 52.7 678 available (625 GB free)
  However, if I select all the files in the root (c:\) including hidden and system, said properties dialog box I used GB 55.5, which is closer to 3 GB.
  My question is if there is some sort of disc error, or there may be some unknown compressed files.

  Note: Windows says I have MORE free space than I can actually count.

  Thank you!

  The disk properties is accurate.

  Calculated by the Explorer file sizes can be inaccurate because of double counting of hard links combined with omission of records for which the current user has no access permissions. For example, Windows\System32 consists largely of hard links in Windows\WinSxS.

  These articles, though ancient, explain which may explain the observed differences.

• Free space on VMFS recovery?

  Y at - it a command that will allow me to zero free space on VMFS volumes to be picked up by our SAN please?

  I saw some contradictory suggestions but nothing concrete.

  I have running on the VMFS virtual computer so he needs to be 'safe '.

  Thank you

  In doing so the first time, I prefer to create a smaller virtual drive (for example 100 GB) to see how the system behaves.

  Make sure that sufficient free disk space if you have disks provisioned thin and/or instant!

• I want to reinstall Windows 7 Home Premium so that I can format my drive hard as free space automatically reduced.

  I want to format my drive hard as free space automatically reduced. I have windows 7 Home premium authentic (built with my acer aspire 5742)

  Original title: relocation

  The recovery 'hidden' Acer Partition should be left intact.

  But you do not what you should have done when you bought your Acer machine; know-how in case of hard drive failure recovery disks.

  Here is how to do this with an Acer:

  "How can I create a set of the backup recovery disks?

  http://Acer.custhelp.com/app/answers/detail/A_ID/12866/kW/recovery%20disk

  Your Acer computer includes Acer eRecovery Management software that allows you to perform operations of restore directly from your drive hard disc , which allows a faster recovery process and no need for discs. Acer eRecovery Management does, however, allow you to create recovery discs. The recovery disks will allow you to restore your computer something happened to your hard hard disk .

  Note: According to Acer computer you have your Acer eRecovery Management version may be slightly different, but the ability to create your discs will be available.

  To create your recovery discs backup follow these steps:

  1. Click on the Start menu, and then click all programs.
  2. In the list of programs, click the Acer file, and then click the Acer eRecovery Management .
  3. User account control Windows may request your permission to run this program, click Yes.
  4. In the Acer eRecovery Management window left click backup, and then click create a default disk factory.

     Note: If you use a laptop or netbook, you will be asked to connect your power adapter, make sure that the power adapter is plugged in before continuing, and then click OK.

  5. In the page to create a default disc factory select the drive you want to use for burning the recovery media, and then click Start.
  6. The disc is ejected whenever he has completed burning, if several drives are required insert a new disc when you are prompted, and then click OK.

  The other option available is to create drivers and Applications Disc. You can use this to create a backup disk to install specific drivers without destroying the entire operating system and applications.

  To create a drivers and Applications disc, follow the steps below:

  1. Click create disk drivers and Applications.
  2. On the page create drivers and Applications disc select the drive you want to use for burning the recovery media, and then click Start.
  3. Whenever it has finished burning, the disc is ejected.

  Note: If the computer does not have an internal optical drive, an external optical drive will create a set of Acer Recovery media.

  See you soon.
