• Add more space to the ASM disk group

  Hi all

  I am new to the DBA role and also in a process of learning. I need your help in putting a space at the ASM disk group. My VMware admin will add disk space to the virtual machine, and then the Linux admin will add space on Linux servers. Finally, I think I need to rebalance the database disk group to view the extra space. I'm not sure of what all the steps involved in this process. I like to read the Oracle Documentation, but I'm blurry and hesitant. Please let me know the steps to follow to add the ASM disk group space.

  We use

  Oracle DB version 11.2.0.3.0

  Linux version: 2.6.18 - 238.12.1.el5

  Thanks for your help

  No....

  You don't need any instance restart. More when you add a disk to a diskgroup, all rac nodes can see.

  just...

  You should add a node and watch v$ asm_operation...

• Create the ASM disk groups instance is not found

  
  Hello

  I just started to learn Oracle, very inexperienced database in Oracle.

  I have a problem to create an ASM instance. My environment is SUSe Linux Enterprise 11 64-bit, I am creating an instance ASM 11.2.0

  1. when I create ASM instance, I couldn't find ASM disks, if an ASM Instance could not be created.

  2. when I search on the internet on the creation of the ASM disk, it seems that I need to connect to the instance ASM as ASMSYS, but I have not an ASM instance is runing so ASM DISK groups has not can be created.

  I feel that I'm at an impasse.

  Could someone help me?

  Thank you.

  You may need to configure the udev subsystem to set permissions of the device and configure the parameter diskstring ASM or install Linux ASMLib, that supports both and more.  In any case, you will need to provide more details and probably do some research to learn more about the basic concepts. To install Oracle ASM is not click and play.

• How to move or migrate whole directories between ASM disk groups?

  Hi all!
  
  I'm playing with Oracle ASM and Oracle Database 11 g R1, I am a student. It's just for testing purposes.
  
  Features of the computer are:
  Processor: Intel Pentium 4 HT 3.00 Ghz.
  Memory RAM: 2 GB.
  Hard drive: 250 GB
  O.S.: Windows XP Professional Edition SP 2.
  
  I installed Oracle ASM, I have created an ASM disk group (+ FRA), I installed Oracle Database and I created a test database. The database works correctly on the ASM disk group. Days, I got help on the initialization parameters, DB_CREATE_FILE_DEST, DB_CREATE_ONLINE_LOG_DEST_1, DB_CREATE_ONLINE_LOG_DEST_2 and DB_RECOVERY_FILE_DEST, according to their function, I created another 3 ASM (+ FILES, LOG1, LOG2) disk groups. There are four initialization settings pointing to its corresponding ASM disk group. As you can deduce, for the time of installation of the Oracle database, I used the ASM '+ FRA' disk group and inside the directories were created: CONTROLFILE, DATAFILE, ONLINELOG, fichier_parametres, TEMPFILE, and the SPFile.
  
  My point is that I want to move or migrate the DATAFILE, fichier_parametres, TEMPFILE directories and the SPFile to '+ FILES', ONLINELOG and CONTROLFILE to '+ LOG1' and '+ LOG2', in this way, the ASM '+ FRA' disk group will contain the Flash recovery area only. What is the procedure for that?
  
  Thanks in advance!

  Hello

  There are two approaches that you can use, here are some
  -To move the data file, start the database in State of Mt.
  RMAN > copy datafile '+ FRA/xxx' to '+ FILES1 ";
  SQL > alter database file rename '+ FRA/xxx' '+ fichiers1/xxx. "

  -To move the temporary file
  SQL > alter tablespace TEMP add tempfile '+ FILES1' SIZE 10 M;
  SQL > alter database file temporary '+ FRA/xxx' drop;

  -To move onlinelog
  SQL > alter database add logfile Member '+ LOG1' group 1;
  SQL > alter database add logfile Member '+ LOG2' group 1;
  SQL > modify the members of database drop logfile "+ FRA/xxx."

  -To move controlfile
  SQL > restore controlfile on '+ FILES1' of '+ FRA/xxx. "
  the spfile update to reflect the new location of the controlfile

• Difference between ADVM Volume and filesystem ACFS ASM disk group

  Q1. What is the difference between an ASM disk group and a Volume of ADVM?

  In my opinion, an ASM disk group is actually a logical volume to the database (including the FRA files) files.

  11 GR 2 appears to have introduced the notions of volumes ADVM and filesystems ACFS.

  11 GR 2 ASM disk group can contain:

  • ASM disks
  • Volumes ADVM
  • Filesystems ACFS

  Q2. ADVM volumes appear to be dynamic volumes.

  However is it therefore not effectively overlaying a logical volume (the volume ADVM) under ASM disk group (conceptually a logical volume as well)?

  Even worse, if you left the ASM disk group redundancy in hardware RAID / SAN level (as recommended Oracle), you actually have 3 layers of logical disk? (ASM on top of ADVM on top of RAID/SAN)?

  Q3. If it is 2 layers of logical disk (i.e. on top of ADVM ASM), what makes this better than 2 layers using a 3rd party volume manager (for example the DSO at the top of the 3rd party LVM) - something Oracle encourages against?

  Q4. ACFS file systems, seem to be file systems clustered for not including ORACLE_HOMEs database files, application exe etc (but NOT GRID_HOME, OS root, OCR or voting records)

  Can you create / modify filesystems ACFS using ASM.

  The diagram of topology of oracle for ASM in ASM 11 GR 2 administration guide, says ACF in ASM. I'm not sure about that if ACFS belongs to ASM or ASM is located at the top of the ACF?

  Q5. Connected to the 4th quarter. There seems to be a number of different ways, ACFS file systems can be created? Which of this is the valid methods?

  • Thanks to ASM?
  • through native OS file system creation?
  • through OEM?
  • through acfsutil?

  my head explodes

  Any help and clarification appreciated

  Q1 - volume ADVM is a type of special file created at the DG of the DSO.  Once created, it creates a block device on the BONE itself which can be used as any other block device.  http://docs.Oracle.com/CD/E16655_01/server.121/e17612/asmfilesystem.htm#OSTMG30000

  Q2 - the asm disk group is a group of disks, not really a logical volume.  It combines the attributes of both when it is used for purposes of database as the database and some other applications know how to talk about Protocol 'ASM '.  However, you won't find all the versatile applications that can do.  In addition, some clients prefer to deal directly with files and devices of volume systems which ADVM is forced to make.  In your thinking, you have 3 layers of logical disk, but each of them provides features and different attributes.  This is not a bad thing, though, as each has a slightly different purpose - os file system\device, specific database and storage-centric.

  Q3 - ADVM is specifically developed to extend the features of the DSO for use by General applications of BONE.  It includes the performance of database features and is tuned to work well in this situation.  Because it is developed in-house, it benefits from the design of ASM model.  In addition, rather than having to communicate with several vendors for support, your support is limited to calling Oracle, a single window.

  Q4 - you can create and modify filesystems ACFS by using command line tools and the ASMCA.  Creation and modification of logical volumes coming through SQL (ASM), asmcmd and ASMCA.  EM can also be used for the two elements.  ACFS is located at the top of the ADVM, which is a file in an ASM disk group.  ACFS is aware of the characteristics of the ASM\ADVM volumes and tunes it's IO make best use of these features.

  Q5 - several ways:

  1) connect to ASM with SQL, use 'alter diskgroup add volume' as Mihael points out.  This creates an ADVM volume.  Then, put in shape volume using the "mkfs" (* nix) or acfsformat (windows).

  (2) use ASMCA - a GUI to create volume and a file system.  Probably the easiest if your head is explosion.

  (3) use "asmcmd" to create a volume and 'mkfs' to put in shape file ACFS system.

  Here is information on the ASMCA, with examples:

  http://docs.Oracle.com/CD/E16655_01/server.121/e17612/asmca_acfs.htm#OSTMG94348

• How to check the space on the asm and raw device?

  Hi all
  
  I want to know how to check the space on the device of the DSO.
  We use a feature of the asm, which is on a raw partition.
  Our archive is full. I need to check the space on asm archve partiotion.
  How can I check the destination space archive?
  We are using partition raw device for crs and voting system.
  How can we check the space on the raw device and how do know us which device is currently in use and are not in service
  
  Thanks in advance

  4 - 5 raw partitions...
  What version of oracle?
  Install the OCR + VOTE in gross unit better than OCFS2. If you use 10g to 11 GR 1 material.

  If use 11 GR 2, take the OCR + VOTE in ASM disk group.

  You can check what raw OCR device:
  $ ocrcheck

  VOTEDISK:
  $ crsctl query css votedisk

  On 10g if using the raw device for OCR + votedisk: recommend 1 file = 250M
  11g recommend 1 file = 512M

  Good luck

• How to solve the problem of 'ASM disk group is inaccessible' slave VM rac2?

  People,
  
  Hello. I want to install Oracle 11 g RAC 2 using 2 virtual machines (VM main rac1 and rac2 VM slave) with Oracle Linux 5.6 according to the website http://appsdbaworkshop.blogspot.com/2011/10/11gr2-rac-on-linux-56-using-vmware.html

• How to increase space of a page in the application designer?

  People,
  
  Hello. I developed a page in the application designer.
  
  I need to place several records with several fields on the page. But all of the space of the page is not enough to place the fields. We must use a vertical scroll to increase the space on the page to contain all fields. But I don't understand how this feature.
  
  Can people tell me how to increase space of a page in the application designer to y to keep many fields?

• Should we leave how much free space on the C drive before affecting the performance and speed?

  Hello!

  Hard drive of my new PC (C) is 1 TB (processor Samsung 7i, Windows 8.1). It doesn't have any other disk/partition. How this space is safe to use to store large files (videos, esp., stored in the native video library file) without harming the performance and speed?

  And if I create another partition (D) and just use it for storage, it will make much difference compared to the above?

  Thank you!

  Planning your Partitions

  The Question

  Partitions, how much should I have on my hard drive, what do I use
  each of them for, and what size should each one be?

  It s a common question, but unfortunately this doesn t have a
  only simple, just answer to all the world. A lot of people will respond with
  the way they do, but their response isn't necessarily best for the
  person seeking (in many cases it isn't right even for the person)
  response).

  Terminology

  First, let's rethinking the terminology. Some people ask "should I".
  partition my drive? That s the wrong question, because the
  the terminology is a little strange. Some people think that the word
  "partition" means divide the drive into two or more partitions.
  That s not correct: to partition a drive is to create one or several
  partitions on it. You must have at least one partition to use
  He who think they have an unpartitioned disk actually
  have a player with only one partition on it and it s normally
  Called C:. The choice you have is to have more than one
  partition, not that it's the partition at all.

  A bit of history

  Back before Windows 95 OEM Service Release 2 (also known as Windows
  95 (b) was published in 1996, all MS-DOS and Windows hard drives have been set
  using the file system FAT16 (except for very tiny to aid
  FAT12). That 16-bit only because were used for addressing, FAT16 has a
  maximum 2 GB partition size.

  More than 2 GB of hard disks were rare at the time, but if you had
  one, you must have multiple partitions to use all the available
  space. But even if your drive was not larger than 2GB, FAT16 created
  Another serious problem for many people - the size of the cluster has been
  more great if you had a larger partition. Cluster sizes increased from 512
  bytes for a partition to no greater than32Mb all the way up to 32 KB for a
  partition of 1 GB or more.

  More the cluster size, the space more is wasted on a hard drive.
  That s as space for all the files is allocated in whole clusters
  only. If you have 32 KB clusters, a 1 byte file takes 32 KB, a file, a
  greater than 32 k byte takes 64 k and so on. On average, each file
  about half of his last group waste.

  If large partitions create a lot of waste (called "soft"). With a 2 GB
  FAT16 drive in a single cluster, if you have 10,000 files, each
  lose half a cluster of 32 KB, you lose about 160 MB for relationships. This s
  back in an important part of a player that probably cost more than $400
  1996 - around $ 32.

  So what did the people? They divided their 2 GB drive in two,
  three or more logical drives. Each of these logical drives has been
  smaller the real physical disk, had smaller clusters, and
  so less waste. If, for example, she was able to keep all the partitions
  less than 512 MB, cluster size was only 8 KB, and the loss was reduced to a
  a quarter of what it would be otherwise.

  People partitioned for other reasons also, but back in the days of
  FAT16, it was the main reason to do so.

  The present

  Three things have changed radically since 1996:

  1. the FAT32 and NTFS file systems came along, allowing a larger
  partitions with smaller clusters and so much less waste. In
  with NTFS, cluster sizes are 4 K, regardless of the size of the partition.

  2 hard drives have become much larger, often more than 1 TB (1000 GB) in
  size.

  3 hard drives have become much cheaper. For example, a 500 GB drive
  can be bought today for about $50. That s 250 times the size of this
  Player 2Gb typical 1996, about one-eighth of the price.

  What these things mean together which is the reason to be old to have
  multiple partitions to avoid the considerable wastage of disk space left.
  The amount of waste is much less than it used to be and the cost of
  that waste is much less. For all practical purposes, almost nobody does
  should no longer be concerned about slack, and it should no longer be
  has examined when planning your partition structure.

  What Partitions are used for today

  There are a variety of different ways people put in place several
  scores of these days. Some of these uses are reasonable, some are
  debatable, some are downright bad. I'll discuss a number of Commons
  partition types in the following:

  1. a partition for Windows only

  Most of the people who create such a partition are because they believe
  If they never have to reinstall Windows properly, at least they
  He won t lose their data and he won t have to reinstall their applications.
  because both are safe on other partitions.

  The first of these thoughts is a false comfort and the second
  is downright bad. See the analysis of the types of partition 2 and 4
  below to find out why.

  Also note that over the years, a lot of people who find their windows
  partition that has begun to be the right size proves to be too
  small. For example, if you have such a partition for Windows and later
  upgrade to a newer version of Windows, you may find that your Windows
  partition is too small.

  2. a partition for installed programs

  This normally goes hand in hand with the partition type 1, a partition for
  just Windows. The thought that if you reinstall Windows, your
  installed application programs are safe if they are in another
  partitions is simply not true. That s because all programs installed
  (with the exception of an occasional trivial) have pointers to the inside
  Windows, in the registry and elsewhere, as well as associated files
  buried in the Windows folder. So if Windows, pointers and
  the files go with it. Given that the programs need to be reinstalled if Windows
  the fact, this reasoning to a separate partition for programs not
  work. In fact, there is almost never a good reason to separate
  Windows of the software application into separate partitions.

  3. a partition for the pagefile.

  Some people think mistakenly that the pagefile on another
  score will improve performance. It is also false; It doesn t
  help and often I hurt, performance, because it increases the movement of the head
  to get back to the page to another file frequently used
  data on the disk. For best performance, the paging file should normally
  be on the most widely used score of less used physical player. For
  almost everyone with a single physical disk than the same drive s
  Windows is on C:.

  4. a partition for backup for other partitions.

  Some people make a separate partition to store backups of their other
  or partitions. People who rely on a "backup" are a joke
  themselves. It is only very slightly better than no backup at all.
  because it leaves you likely to be simultaneously the original losses
  and backup for many of the most common dangers: the head crashes and other
  types of drive, serious glitches to power failure, near lightning
  strikes, virus attack, even stolen computer.  In my opinion,.
  secure backup must be on a media removable and not stored in the
  computer.

  5. a partition for data files

  Above, when I discussed separate Windows on a clean partition,
  I pointed out that separate data from Windows is a false comfort if
  He of done with the idea that data will be safe if Windows ever
  must be reinstalled. I call it a false comfort that's because
  I'm afraid many people will rely on this separation, think that their
  data are safe there and so do not take measures to
  Back it up. In truth the data is not safe there. Having to reinstall
  Windows is just one of the dangers to someone a s hard disk and not
  probably even one. This kind of "backup" falls into the same
  category, as a backup to other partitions partition; It lets you
  sensitive to the simultaneous loss of the original and the backup on many of
  the most common dangers that affect the entire physical disk, not
  just the particular partition. Security comes from a solid backup
  diet, not how partition you.

  However, for some people, it may be a good idea to separate Windows and
  programs on the one hand of the data on the other, putting each of the
  two types into separate partitions. I think that most people
  partitioning scheme must be based on their backup system and backup
  plans are generally of two types: whole hard disk imaging
  or data only backup. If you back up data, backup is
  usually facilitated by the presence of a separate with data only partition;
  to save just the score easily, without having to
  collect pieces from here and elsewhere. However, for
  those who backup by creating an image of the entire disk, there is
  usually little, if any, benefit the separation of data in a partition of
  its own.

  Furthermore, in all honesty, I must point out that there are many
  very respected people who recommend a separate partition for Windows,
  Whatever your backup plan.  Their arguments haven t convinced
  me, but there are clearly two views different here.

  6. a partition to image files

  Some people like to deal with the images and videos as something separate
  other data files and create a separate partition for them. To my
  the spirit, an image is simply another type of data and there is no
  the advantage in doing so.

  7. a partition for music files.

  The comments above related to the image files also apply to music
  files. They are just another type of data and must be dealt with the
  just like the other data.

  8. a partition for a second operating system to dual-boot to.

  For those who manage several operating systems (Windows Vista, Windows
  XP, Windows 98, Linux, etc.), a separate partition for each operating
  system is essential. The problems here are beyond the scope of this
  discussion, but simply to note that I have no objection to s
  all these partitions

  Performance

  Some people have several partitions because they believe that it
  somehow improves performance. That s not correct. The effect is
  probably low on modern computers with modern hard disks, but if
  whatever it is, the opposite is true: more music mean poorer
  performance. That's because normally no partition is full and it
  so are gaps between them. It takes time for the drive s
  read/write heads to cross these gaps. Close all files
  are, faster access to them will be.

  Organization

  I think a lot of people overpartition because they use scores as a
  organizational structure. They have a keen sense of order and you want to
  to separate the apples from the oranges on their readers.

  Yes, separating the different types of files on partitions is a
  technical organization, but then is to separate different types of
  files in folders. The difference is that the walls are static and
  fixed in size, while the files are dynamic, changing size automatically
  as needed to meet your changing needs. This usually done records
  a much better way to organize, in my opinion.

  Certainly, partitions can be resized when necessary, but except with the latter
  versions of Windows, which requires a third-party software (the and the
  possibility to do so in Windows is primitive compared to the third-party
  solutions). These third party software normally costs money and not
  any point and how stable it is, affects the entire disk.
  with the risk of losing everything. Plan your partitions in
  first place and repartitioning, none will be necessary.  The need
  to repartition usually occurs as a result of overpartitioning in
  the first place.

  What often happens when people organize with partitions instead
  records are that they make a miscalculation of how much room they need on each
  This partition, and then when they run out of space on the partition
  When a file is logically, while having plenty of space
  on the other hand, they simply saving the file in the score of "poor".
  Paradoxically, therefore, results in this kind of score structure
  less organization rather than more.

  So how should I partition my drive

  If you read what came before, my findings will not come as a
  surprise:

  1. If your backup set is the image of the entire disk, have just one
  single (usually c partition :));

  2. If you backups just data, have two partitions one for Windows and
  application programs installed (usually c :)), the other for data
  (normally D :).)

  With the exception of multiple operating systems, it is rarely
  any advantage to have more than two partitions.

  I am facing problems of space on my hard drive and the Keychain password... Need help please...

  And, how do you think these two are related? Or you are having problems with both? In all cases, you will need to sharpen the issue, then we know what you mean.

  How to free space on the hard drive

  1. You can remove the data from your file except for the folder/Home/Library /.
  2. Visit The FAQ XLab and read the FAQ on the free space on your hard drive.
  3. See also release space on your Mac OS X startup disk.
  4. See where my disk space gone?.
  5. Remember to empty the Recycle Bin to reclaim space.
  6. Replace the disc with a larger. Check out OWC of readers, tutorials and boxes tools.
  7. Use OmniDiskSweeper 1.8 or GrandPerspective to search your drive for large files and where they are.

  the hard drive of my computer is purchased full.i a drive.how external hard change outside the primary disk so I can download music easily.right now my external backup just my computer that isn't doing me good

  original title: external hard drives

  You don't want to change your external drive to your main drive.

  You can move your music files on the external drive - or you can move other data on the disk to make room for your music on the internal drive.

  What applications do you use to play music?

  As described in the first link below, you can move your full "My Documents" folder on the external drive.  Alternatively, you can simply move your music files.  If such an arrangement would give you a satisfactory performance, however, depends on how your external drive is connected (for example, USB 1.1, USB 2.0, USB 3.0, eSATA, Firewire, network) and other hardware features of your computer.

  Not all of the following conditions will be applied to you, but some of the tips can be useful.

  There are a number of things you can do to- temporarily - free up disk space.  The only real solution, however, is to get a bigger internal hard drive.   You can move the data to your external drive, but if it's the data that you use frequently, slower access times may annoy you.  Therefore, I do not recommend that you move your My Documents folder in its entirety on the external drive, but you can certainly do this by following the related instructions.

  • You can run Disk Cleanup (start > run > cleanmgr > OK)
  • You can reduce the size allocated for the restoration of the system to about 1 GB (right click on desktop > properties > system restore > settings)
  • You can disable hibernation (if you don't use it) (right click on an empty spot on the desktop > properties > screen saver > power > Hibernate)
  • You can disable the indexing of the drive, which will also speed up your computer a bit (http://lifehacker.com/031440/turn-off-indexing-and-speed-up-windows-xp)
  • You can reduce the size of your Internet browser cache (depending on the browser that you use)
  • You can remove most of the $NTUninstallKBxxxxxx files $ following the directions here: http://windowsxp.mvps.org/Hotfix_backup.htm (read the warnings in the gray box first)
  • See also:

  " How to recover disk space on Windows Server 2008 and Windows XP computers? ."

  " Forty ways to free disk space ."

  But none of these answers you will earn really large amounts of space for very long.  The term solution time is a bigger hard drive.

  In the meantime, download and run JDiskReport, that will show you graphically what files take up more space and seem to so indicate what files you must move it to your external drive.  If you want to move an application, you will need to uninstall and then reinstall it specifying your external drive as the installation location.  You can not simply move the files.
