• How to increase space in the ASM disk groups?

  Hi all

  I'm a newbie DBA in my team and today morning received an alert of OEM which:

  Target name = + ASM_ZEUS.techiebros.com

  Message = disk group DATA requires rebalance because at least a disk space is low.

  Any solution?

  To fix this, you can run this command: Alter diskgroup ASMDB add drive "here, the way of the new disk" Rebalance power 4 WAIT;

  After that, you can see through the 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.

• 1 the ASM disk group are several DBs CARS?

  DB version: 11 GR 2
  Platform: Sun OS 5.10
  Number of nodes: 2
  
  We currently have a 2 DB RAC node called PMDB1 running with a group of disks called 1 tera bytes DG1_DATA.
  We would like to add another data base of this group.
  This DB allows the same group of disks (DG1_DATA) whose use PMDB1?

  Hi Haiti

  This DB allows the same group of disks (DG1_DATA) whose use PMDB1?

  Yes. No problem.

  An instance of ASM to the CCR can be associated with instances of the several DBs. right?

  Right

• Question about the use of size mixed with ASM disk groups

  I support a RAC 10 g 10.2.0.3 running and using ASM cluster. We currently have a group of data disks, which is 600 GB in size, consisting of 3 individual raw disk 200 GB devices. The RAC cluster runs on a server pSeries IBM using AIX 5.3
  
  I need to add more space, but the system administrator can give me only 100 GB in the new raw device. What will be the impact, if any, the addition of this feature of smaller crude disk in the same data ASM disk group? I understand that ASM is trying to "balance" the general use of each raw device. ASM still works very well, or will he constantly try to rebalance the disk group because the a raw device is only half of the other three? Any help and advice would be greatly appreciated. Thank you!

  It works, I do the same thing in a production database. What happens is, asm will distribute data on the size of the disks. 200 GB drives will get two times more data than the 100 GB drive. The downside is that it will also result in an unequal distribution of the IOPS / s: adults discs will be achieved more often.

• 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:

• 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

• Oracle 10g RAC + ASM + Data Guard: Question on the new disk group.

  Hello
  
  One of our clients is to have Oracle 10 g RAC + ASM + Data Guard. Database is the disk DATA_DG1 group and FRA is on FLASH_DG1. Data Guard is a single instance on ASM.
  
  To add more space, we can create another disc of the Group DATA_DG2 on Prod ASM and Data Guard ASM env, replication continues without any problem. Will be archiving logs shipped to the second disk DATA_DG2 group and applied without any configuration changes?
  
  Rgds,

  Yes, it sounds great.

  You should be fine with the implementation of these measures and the dataguard should continue on as usual.

  Just make sure that you are dealing with a physical standby that has not the conerts file name defined.

• 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

  As we see above shows the command $ ps - ef | grep pmon, my question is:

  First of all, are ' 16219 8602 ora11g 0 "process ID?

  Secondly, we need to kill one by one? For examples: kill-9 ora11g? Kill-9 16219?

  Laughing out loud. It's not the running process.

• the ASM disks can be in a different Partition for a database

  Hi all
  I have 2 datababase on the server. I save the data file on MDMDISK1 for the MDM and DWHDISK1 database to the DWH database.
  I can add/dev/sdd5, / dev/sdd6, / dev/sdd7 to DWHDG1 disk group to give more space to the DWH database.
  
  Table of Partition disk configuration
  Group name size GB ASM Disk Disk drive
  / dev/SDS (MON) 107
  / dev/sdd1 7 CRSDISK1
  / dev/sdd2 7 CRSDISK2
  / dev/SDS3 7 CRSDISK3

  but I wanted insurance with people with experience as you go this drive on differnet LUN will not impede performance.

  A LUN is a logical unit - it may be a single physical disk. It may consists of 20 physical drives. If the LUN itself does not determine the performance. Performance is determined by the parts in movement under it.

  Multiple LUNS to the same diskgroup using or the volume of file system is a common practice. If this would be a problem (performance or otherwise) depends on the cloth under the LUN.

  For example, a logic unit number could be RAID5 and another logic unit number can be RAID0 + 1. Mixture of different RAID levels is not really a good idea.

  A LUN can be a storage on a San and accessible via the fiber channel. Another logic unit number could be an iScsi device, accessed through intellectual property. Mix very different storage architecture and storage protocols are not a good idea.

  A LUN can be RAID0, through fiber double channels connected to a switch, for the storage of 1 storage server. Another logic unit number can also be RAID0 and accessible through the same fiber channels and switch, but since the storage server 2. Whereby the RAID levels are the same and the storage Protocol and infrastructure the same - and that will not only make a compatible mix, but can actually increases the redundancy if you use these as disk mirrors ASM (which means that ASM can lose the server storage 1 or 2 and still works).

• Does anyone know how I could free more space/add more space to my backup drive?

  Original title: save file/disk

  Dear all,

  As usual, I used part of my hard drive to back up files, etc.

  In my last scheduled backup, windows informed me that he could not perform the cause there wasn't enough space in my backup disk.

  Does anyone know how I could free more space/add more space to my backup drive?

  Thanks in advance

  George

  Please be aware that the second part of your hard drive backup is
  far the lowest form of backup exists. It is only very
  slightly better than no backup at all, because it let you
  sensitive to the simultaneous loss of the original and the backup on many of
  the most common dangers: drive failure, head goes down, severe feeding
  glitches, near lightning, virus attacks, same flight of the
  computer.

  In my view, secure backup must be on a unguarded and removable media
  in the computer. For backup really secure (required, for example, if the)
  the life of your company depends on your data), you should have several
  generations of backup and at least one of these generations must be
  stored off-site.

• Tools to prepare the ASM disks

  What is the difference between the asmca and oracleasm?

  Hello

  ' / usr/bin/oracleasm "ASMLib is a library of optional support for the Oracle database automatic storage management feature (this (RPM) is not a part of the Oracle Grid infrastructure Installation). ASMLib allows a more efficient Oracle using ASM database that can join groups of disks it uses.

  ASMLib is available on Linux Plataform.
  http://www.Oracle.com/technetwork/topics/Linux/asmlib/index-101839.html

  ASMCA - ASM Assistant de Configuration Oracle is an Oracle Grid Infrastructure installation utility that supports the installation and the configuration of the ASM instances, groups of disks, volumes and Oracle Automatic Storage Management Cluster File System (Oracle ACFS). It must be used in all the platform to configure and manage the DSO.
