• Reinstallation of Oracle 11 g 2 RAC grid problem - ASM disk group

  People,
  
  Hello.
  
  I want to install Oracle 11 g RAC 2 with 2 Virtual Machines (rac1 and rac2 which BONES are Oracle Linux 5.6) in VMPlayer.
  
  I was installing Infrastructure of grid using runInstaller in the first rac1 VM from step 1 to step 9/10.
  
  On 9/10 in the wizard step, by chance, I touch the mouse, and the wizard disappeared.
  
  The grid in the 2 VMs installation directory is the same: / u01
  
  I have to make sure that everything is correct, delete the directory/U01 to 2 virtual machines and install again the grid in rac1.
  
  I realized that this is not the right way to remove/U01. The right way is to follow the tutorial
  http://docs.Oracle.com/CD/E11882_01/install.112/e22489/rem_orcl.htm#CBHEFHAC
  
  But I have deleted/U01 and must correct one by one. I reinstall the grid and get the error message in step 5 of 9 as follows:
  
  [INS - 30516] Please specify unique disk groups.
  [INS-3050] ASM disk group empty.
  Cause - the installer has detected the name of Group of disk already exists on the system.
  Action - specify the different disk group.
  
  In the wizard, the old disk group name is 'DATA' and his candidate records (5 ASMDISKs) are gone. I try to use another name "DATA2", but no ASMDISKs are "candidate records. For "All discs", it is impossible to select all ASMDISKs.
  
  I want to use the same disk group ASM 'DATA' and do not want to create a new disk group.
  
  My question is:
  
  How to make previous ASM disks and his group of 'DATA' therefore "Candidate records" who can use again?
  
  
  Thank you.

• If you use network storage, configure ASM disks with external redundancy groups

  Hi Experts,

  If you use network storage, configure ASM disks with external redundancy groups. Don't use groups of Oracle ASM failure. Oracle failure groups consume cycles additional CPU and can run in unpredictable ways after suffering from a disk failure. When you use external redundancy, disk failure are transparent to the database and do consume no additional database CPU cycle, because it is discharged on storage processors.

  This does not mean

  • RAID 1 + 0 for diskgroup + REDO1
  • RAID 1 + 0 for diskgroup + REDO2
  • RAID 5 for diskgroup + DATA
  • RAID 5 for diskgroup + FRA

  Is this one suggested, the recommended best practices for oracle on VMWARE?

• Antivirus with ASM disk considerations

  Hi all

  We are currently running Oracle 10 g on Windows Server 2008 R2 using file storage system.  We seek to upgrade to 11g and use of ASM disks rather than the file system.  I am aware that there are many considerations here, but I have been asked specifically about how RAW disks and our antivirus will interact.  For the moment, we use the Center Endpoint Protection system on the database server, and then exclude us certain types of files associated with Oracle (DBF, CTL etc.).  This configuration meets the DBA and infrastructure.  Once we start using ASM if, something will have to change because we will not be able to exclude specific file types.

  I would be interested in advice / opinion that anyone was around that.  More precisely:

  1. is it possible for a disc of ASM to be infected by a virus?

  2. the AV software is even capable of preventing infections on ASM disks? (maybe its not relevant according to the answer to the first question)

  3. we are likely to see some performance issues with AV software running on our database server, because the current set up described above works fine but is replaced by ASM disks?

  Any help or advice welcome

  Thank you

  Andrew

  Disc GROSS means that there is no file system. No virus software can analyze the volumes of the ASM, which can only be used by an Oracle database and what data structure is known only for Oracle. Unless you install any ACF volume, which allows the storage of ASM data that can be accessed by the operating system, software Anti Virus cannot analyze data.

  However, the Anti Virus software can interfere with e/s of Oracle applications, which you will certainly not want and that has really no sense. Unfortunately, any installation which is connected to the Internet without any protection against the malware running MS Windows is a suicide. To be honest, I never want to install and run the Oracle database on a MS-Windows Server and see no valid reason for it. There are much better alternatives, such as Oracle Linux, which is also free.

• Property of asm disk

  Hi all, I want to install Oracle 11 g Linux for autonomous database.so grid infrastructure I can install DSO as a user of grid and also created the disks as a user of the grid. Now., during the creation of the db in oracle user disks don't leave to use. Since the grid is the owner. How can I trobleshoot it. Please, share your ideas.

  Thank you

  Hello

  I guess you also created ASM diskgroup to the database. If you are able to create diskgroup, nothing wrong with permissions on the disks.

  Problem creating database, is to your own database software (oracle) is a member of the group 'asmdba '? If not, add it. I don't think that any other special permissions must be granted to the user oracle.

• Adding a device to ASM disk using asmtool

  Hello

  I create ASM disks.

  Background: Oracle enterprise linux 6. I'd partition the shared disks (SCSi) during the installation of Linux (don't know what to do, I just did).

  Now if I run oracleasm createdisk, it is said that the devices are busy. No, I removed the mounts of the devices in/etc/fstab. Now createdisk said that "the device is not a partition. Now I use asmtool command instead:

  / usr/sbin/asmtool - c-l/dev/oracleasm n OCRVOTE s/dev/sdc - a force = yes

  That works fine, but I need to add more then one device to drive OCRVOTE. If I do

  / usr/sbin/asmtool - c-l/dev/oracleasm n OCRVOTE s/dev/sdd - force = yes

  It is said: asmtool: unable to create 'OCRVOTE' ASM disk: file exists

  Hello

  You're basically labelling records at the level of the BONE.

  This name must be unique.

  You must give the label name different labelling while.

  / usr/sbin/asmtool - c-l/dev/oracleasm - n OCRVOTE1 s/dev/SDS - a force = yes

  Then use ASM diskgroup in the future.

  Kind regards

• ASM disk added without scan on the second node

  Hi all

  Oracle Version: 11.2.0.3

  I need a help for a problem with the addition of ASM disks.

  It is a node two CARS and a disk group was filled.

  A drive was available as UNUSED001 and so we renamed it ran scan disk and disk added to the diskgroup on node1.

  But, as we have not run scan disk on the second node, the name is still the poster as UNUSED001 and assigned to diskgroup showing as a MEMBER.

  In addition, the renamed disk shows as a MEMBER but not attributed with any diskgroup.

  Usually, when this heppens we have to restart the node to solve the problem, but would like to get idea if this can be fixed without bouncing nodes.

  I restarted node and that fixed the issue.

  Closing this thread.

  Thank you guys.

• Oracle ASM on Windows

  I think I have I need help to get my right to ASM storage. Recently I changed businesses and the new place is a House of Windows, so Oracle databases are all on 2008 R2 machines. I run Oracle RAC on both physical and virtual before, but only in Linux/Unix environments (up to now, I still prefer) so I'm still learning some of the ins and outs. This company seeks also to travel to the RAC, ASM is in the mix. To start my tests, I have implemented an ASM instance for a single host that will eventually become a pole of development taking into multiple databases. However, before I set up data bases, the host is locked up. I think it has something to do with the configuration of the disk, because while the entrapment took place while the virtual machine is idling, several crashes occurred when I try to drop a disc from the asmca utility. I followed the Oracle documentation for Windows platforms, but this documentation does not offer overview of storage on vmware virtualization.

  Here is my configuration:

  VMware: vSphere 5.5

  OS: Windows 2008 R2 Standard

  Memory: 12G

  Storage: OS: 60G; ASM: 20G, 5G, 5G

  Oracle Grid: 11.2.0.4 (more January 2014 CPU)

  Oracle database: 11.2.0.4 (more January 2014 CPU)

  Other details (perhaps important, perhaps not):

  (1) I have a large pages activated

  (2) drives are supplied thin. Note, I always thick-stocked my ASM, but our admin SR records. HE made a policy that all disks must be supplied thin for efficiency. I don't know if this could cause a problem.

  (3) the 3 ASM disks are running using the paravirtualized SCSI driver

  (4) the host also has an OEM 12 c Agent installed and running.

  I'm new on the Windows platform when it comes to Oracle (I managed a lot of SQL Server DBs), blocks do not appear to produce any type of data in the logs.

  Just for someone who comes across this post on the forum, update the ESET software kept interfering with the DSO, so I'm back in business. In response to the previous notice, I am the first full-time, home s/n they hired, and what I learned to work with is regardless of the parade of consultants put in place in recent years. Sometimes you gotta work with what you have. It's kinda a mess overall, to say the least, but I'm slowly getting it resolved. Linux is in the cards, but not in this series of changes.

• 11 GR 2 Grid Infrastructure install - with normal redundancy ASM disk group requires 3 disks?

  
  Hello

  I want to install 11 GR 2 grid Infrastructure in a new environment in cluster - 2 nodes). I use the 11.2.0.4 GI Installer on Oracle Linux 6.5 x 86-64

  However when it is in the installer of GI, it comes to choose the storage Option - I choose ASM disk groups.

  Then change the path of discovery to pick up my candidate ASM disks.

  I enter the disk group name SIR give Normal redundancy, choose 2 discs of candidate and then press < next > to Setup.

  However, I gives me the message

  [INS-30510] Insufficient number of ASM disks selected

  The number of selected disks was inadequate for the level of redundancy selected

  For a disk group with redundancy level "Normal" disks at least "3" are recommended

  I always thought that Redunancy Normal required only 2 discs and high redundancy requires 3 disks?

  No idea what is gpoing?

  Thank you

• 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:

• 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

  Linux version: 2.6.18 - 238.12.1.el5

  No....

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