• paths multiple ASM question

  I'm new in ASM would ask the following question:
  
  I use ASM which for a LUN (dm_0) and FRA as a LUN (dm_1), which comes from external SAN by using the paths were given multiple Oracle driver.
  
  The question is:
  
  will it be a case that in some situations, the reboot to say, the dm_x will be swapped (i.e., DATA-> dm_1) and FRA-> dm_0 so that the ASM is unable to find the right path?
  
  If so, what I need config, say multipath.conf, etc... to make the fixed mapping.
  
  Thank you.

  Hello

  Yes, it's quite possible that the name of the device dm will change after the restart. (Though in my case that's not dm_X dm - X).

  However as long as ASM is able to perceive all the LUNS (Discovery Channel), he needs access (and features dm has the appropriate permissions), the order is not important for the DSO. ASM will scan all disks and identify the drive with the disk header.

  Once again: only ensure that permission on dm used to ASM devices are set correctly and the necessary features dm - X can be found with the discovery of the ASM instance string. The rest will / can be handled by ASM.

• Move the recovery flashback for the systems area no ASM

  Hi all
  
  I want to spend my FRA out of the disc which is housing of the instance data files. I look in the docs and find the following:
  
  Change the Flash recovery area to a new location
  
  If you need to move the area of flash recovery of your database to a new location, then follow these steps:
  
  Start a SQL * Plus, on the target database and change of the DB_RECOVERY_FILE_DEST initialization parameter. For example, enter the following command to set the destination to the ASM disk group disk1:
  
  ALTER SYSTEM SET DB_RECOVERY_FILE_DEST = '+ disk1' SCOPE = BOTH SID ='* ';
  
  After you change this setting, all new flash recovery area files will be created in the new location.
  
  
  What would the syntax alter system to system no - ASM with a single instance (SID), something like:
  
  ALTER SYSTEM SET DB_RECOVERY_FILE_DEST = ' / path/to/new/disk "SCOPE = BOTH SID ="MYSIDACE ";
  
  Thanks for any help.

  What would the syntax alter system to a system with a single instance (SID), something like no - ASM: ALTER SYSTEM SET DB_RECOVERY_FILE_DEST = ' / path/to/new/disk "SCOPE = BOTH SID ="MYSIDACE ";

  You are right, but you do not sid = mysid continuous:

  ALTER SYSTEM SET DB_RECOVERY_FILE_DEST = ' / path/to/new/disk "SCOPE = BOTH;

  Now all new flash recovery area files will be created in the new location. The permanent files (control files and redo log online files), flashback logs, backups of databases, archievelogs can be left in the old FRA. The database will remove them from the old FRA as soon as they are eligible for deletion

  If you want more than all of the files from an MRE old new FIU, follow the link

• accidentally deleted diskgroup including OCR OCR. What should I do to get the OCR?

  OS: Linux redhat 5

  DB version is: 11.2.0.3

  I was trying to reorg the diskgroup and accidentally deleted the diskgroup that including OCR.

  How I can't bring asmca and don't know what to do here.

  I tried to restore the backup, it seems the diskgroup deleted original backup.

  Please help here.

  Thank you.

  You can use the following procedure if diskgroup with OCR is lost.

  1. start a single node.

  2. stop the crs:

  crsctl stop crs f

  3. start the crs in exclusive mode:

  crsctl start crs - Excl.

  4. start ASM, asm_diskstring set (if necessary) and create the diskgroup bearing the same name (ASM may begin with the placeholder file)

  5. the list of OCR, and OCR to restore the most recent backup backups:

  ocrconfig - showbackup

  ocrconfig-restore

  6. stop the crs:

  crsctl stop crs f

  7. If the vote of the files are Ok, restart all nodes.

  On the OTHER - restore files with right to vote:

  crsctl start crs - Excl.

  connect to ASM and asm_diskstring set (if necessary)

  crsctl replace votedisk +.

  crsctl stop crs f

  The compatibility of the DSO should be according to the features you want to use, for example, if you are ready to use ACFS, the value of the parameter must be the value of 11.2. So I will not say that compatibility.asm must be set to 11.2. You should look at the features that you are looking forward to implement and set the value accordingly.

  So, why the disc always showing to v$ asm_disk if it fell? Or is it? I thought that Oracle should drop the disc at the expiration of the timer of the repair, but then why I always see it? I want to add the failed drive to return once again... How can I realize that, if the drive is still a member of the diskgroup of the NEWSPAPER?
  
  Thank you..
  
  Published by: AJ on 09.sep.2011 01:17

  Hello

  the reason behind this, is that a DISC will get status COWARD, if all valid content could be moved to another drive.
  However, in your case your LOG diskgroup consisted only of 2 discs (and 2 failgroups). So when access to a failgroup had disappeared, the whole failgroup was set to offline.
  Now when the repair timer expires the disks to be abandoned. However, it cannot be moved, because the data on the disk can not be moved to other disks.
  So what happens, is that your discs will be defined in the sense of "FORCING", as soon as the data can be rebalanced to another drive (maybe when you add a new drive), the drive really will be abandoned.

  Hello

  If the files on disc with voting rights are in a disk group, know that groups of disks with files Oracle Clusterware (OCR and voting disk files) have a more minimal number of failure than other groups of disks.
  If you create a group of records as part of the installation in order to install the OCR and files on the drive to vote, then the installation program requires that you create these files on a disk group with at least 2 GB of free space.

  A lack of quorum group is a special type of the failure group and these groups of failed disks contain no user data. A group of lack of quorum is not considered when determining the requirements of the redundancy for storage of user data. However, a lack of quorum group account when mounting a disk group.

  For the Oracle Clusterware installation, you must also add the additional disk space for Oracle ASM metadata. You can use the following formula to calculate the disk space required (in MB) for the OCR and voting disk files and metadata from Oracle ASM:

  total = [2 * ausize * discs] + [redundancy * (ausize * (nodes * (+ 1) + 30 clients) + (64 * nodes) + 533)]

  Where:

  redundancy = number of mirrors: external = 1, normal = 2, high = 3.

  ausize = size in megabytes metadata.

  nodes = number of cluster nodes.

  clients - the number of instances of database for each node.

  drives - number of disks in the disk group.

  See the link below for more details...

  http://download.Oracle.com/docs/CD/E11882_01/install.112/e17212/storage.htm#CDEDEEAH

  I recommend you to read the entire section 3.3.1.1.

• How to set permissions for drives avoid the ORA-15063 start-up ASM?

  Hello

  When I try to reboot the DSO after a reboot of the server, I get

  ERROR: diskgroup DATA was not mounted

  ORA-15032: not all changes made

  ORA-15017: diskgroup 'DATA' cannot be mounted

  ORA-15063: ASM discovered an insufficient number of drives for diskgroup "DATA".

  It seems the permission of disks have changed after the reboot. I guess the spfile is inside the DATA diskgroup because it can not even start ASM. When I create a file with values asm_diskgroup and asm_diskstring pfile and 777 on the drive, I managed to start the ASM.

  * .asm_diskgroups = "INDX", "DATA".

  * .asm_diskstring = "/ dev / *'"

  $ oracleasm querydisk p - DATA

  Disk 'DATA' is a valid ASM disk

  / dev/sdb4: LABEL = 'DATA' TYPE = 'oracleasm.

  $ ls-la/dev/sdb *.

  ...

  BRW - rw - 1 root disk 8, 19, 29 mai 10:42 / dev/sdb3 it

  brwxrwxrwx 1 root disk 8, 20, 29 mai 15:17 / dev/sdb4

  ...

  And when I read the documentation I see this ' that the owner of the ORACLE binary file has permissions to read/write on the discs"(so do not run required) but the problem is that this test server should have the same parameters as in production. And the production server has brw - r - for the corresponding disk. So my questions are

  Can it be handled somehow in a different way? How can this have been reached production without the same settings I put in test? Is there an other way around for me in test to achieve?

  The network user (who owns the infrastructue grid) belongs to the same group of test and production. Test and production have ASM version 11.2.0.3, but the different operating system.

  production: 2.6.18 - 274.12.1.el5

  test: 2.6.32 - 504.16.2.el6.x86_64

  As this is my first ASM/grid infrastructure, I don't even know where to begin this review except the support.oracle.com search but I've not found anything except the Action for the error code (which is perhaps the only way around it)

  Any help is appreciated

  Thank you

  / Jenny

  Remember that the permissions of the device must be configured so that the owner of the Oracle database or the process has full access to the appropriate device files. It is not enough to only give ASM full authorization for devices files. ASM provides management for volume, but the database has direct access to device files and ASM does not interfere with inputs and outputs. You can set up groups and owner accordingly. If you have a different owner for ASM, you must assign appropriate groups to give full access ASM configuring oracleasm.

  Thank you all for the reply.

  However, most of the research points to duplicate the order which of course can put new dbname Test in the rman duplicate command.
  However, we use restore/retrieve the rman command, I tried restore database and then retrieve the database, all this worked on the test environment.

  The problem is now the data files are all in this format:
  + DATA/PROD/datafile1, 2, 3.

  My next step is to create a backup controlfile to create the test database. How to point locations of data file in the create controlfile to this script: + DATA/test/datafile1, 2, 3?

  When you use ASM/OMF tasks are easier compared to other file system.
  You don't have to worry about the organization/structure of directories of files or even where to place the files because the ASM will take care of it.

  You need to focus on the parameter 'DB_UNIQUE_NAME' see this example.

  Of the two cases below, I used "swich/set newname" because I restored the database on different DISKGROUP. You SHOULD not use ' swich/set newname' If you use the SAME NAME of DISKGROUP.

  {message: id = 10455101}

  {message: id = 10568466}

  P.S The command "CHANGE" of RMAN you must use it only when you restore your database to different DISKGROUP. If you change only "DB_UNIQUE_NAME" and restore you using NAMESAKE of DISKGROUP you use the "SWITCH" command Only the command "RESTORE/RECOVER"

  If you duplicate database using the rman 'DUPLICATE' command you need not worry about anything, RMAN will place your files on the right place using DB_NAME;

  If you duplicate database using rman "RESTORE" and after that "NEST" rename the database, that you change only uses "DB_UNIQUE_NAME" and rename the database with "NEST".

• ASM Volumes ISCSI thin-set in service in volumes of dirty

  Hi, we have some EBS test case is going and that you are testing auto-prolonger (into reasonable pieces) on an ISCSI volume thin-set in service to the layer of database 11g. Something does not seem right however: in general I see about 55 GB used by data files, but about 95 percent of the thin-set volume in service is marked modified.
  
  Obviously, this sort of deny the utility of thin provisioning at all, but I can't help thinking that there is something else at work here. Does anyone have any experience with this situation and if so what settings can be defined to do what we try to do a work really right?

  ASM is designed to put a wrapper around raw devices leaving (Oracle DBWR, process server) software to read/write directly from a crude into pieces drive "to THE" (AUs being 1 MB by default), rather than "block pieces. For me, the best way to understand it is: the process that wants to work with the disk request ASM where au.

  To do this, ASM itself will have to 'index', the location of each AU and blocking is involved. Which, in turn, would require ASM analyze the whole score to determine locations, which might as well mark the blocks as 'reserved '.

  If my conjecture is true (and seems to be based on "Oracle automatic storage management: under the hood & practice Deployment Guide" (http://www.amazon.ca/Oracle-Automatic-Storage-Management-Under/dp/0071496076) as well as another reading and supported by your conclusion), then it is not a surprise that the entire volume is assigned and be considered dirty.

  Hello
  As you can see there no ASM is registered with RAC. If you are unable to use DBCA fot its, you immediately connect to ASM on the node where it is running and close.

  export ORACLE_SID=+ASM1
  
   sqlplus "/  as sysdba"
  
  shutdown immediate
  

  Delete the password file and the file init of ASM and its entry to/etc/oratab.

  Now again to start over and create a RAC database during which it will also create RAC ASM instances for you. I don't have CARS now, so I'm sorry I can't tell you the screens.

• cDAQ-9178 & NI 9401 - ASM: incremental Rotary encoder works is not beyond a certain frequency

  I use a chassis with a NI 9401 DIO module 9178 cDAQ.  I'm trying to convert the output of a rotary incremental encoder ASM (in radians) to rpm.

  Sensing head (PMIS4-20-50-240kHz-TTL24V-Z0-2M-S)

  Snap ring (PMIR7N-20-50-M-20)

  The encoder outputs 2500 pulses per rev (output 5V TTL).  The maximum speed which will see the encoder is 2800 rpm, which is equivalent to 2800 RPM * 2500ppr/60 = 116,667.67 Hz in terms of frequency.

  Since the NI 9401 of the operations specifications:

  Maximum of the input signal switching frequency by the number of input channels, by channel

  8 input channels... 9 MHz
  4 input channels... 16 MHz
  2 input channels... 30 MHz

  I use only 1 channel, so I'm assuming that the 9401 should be more than capable of handling the 116kHz which the ASM encoder is spit.

  Everything works fine until about 2100 RPM (~ 87, 500 Hz) but then I begin to see a drop in rpm, followed by a flattened behavior, then a slight increase. But never more than 2100 RPM.  Our test unit is inspected for other reasons at the moment so I can't produce a plot of the behavior (I can reupload later).  I think this must be a matter of aliasing with the meter or something of the sort.  I have a digital filter set in place with a minimum of 4.0E pulse width - 6.  It is two times smaller than the width of minimum pulse at a frequency of 116kHz (0.0000085714).  I don't think this should have an impact on the calculation.

  Any suggestions? This value of RPM is essential to our application.

  Thanks in advance,

  A 116 kHz frequency, the period is ~8.57 us, but the pulse width half duty cycle of 50%.  Ascent/descent time factor, and it is quite possible that 4 US is too long for your encoder signal.

  The shape of this graph supports this theory, if we consider that there is variation in the exact pulse of each encoder pulse width.  The shortest pulse is ignored when the filter starts to kick in, and the speed of ROTATION increases pulses longer and longer are ignored then as well.

  Try to decrease the minimum pulse of digital filter (US 2 or even 1 US) width and see how it goes.

• The file 'asms' is required to complete the Windows XP installation?

  Hi all

  One day, I tried to format my hard drive on my computer and now whenever I start it, it says «the installation program restarts...» "and then it takes me to a screen where it shows"the asms file is necessary to complete installation".
  This happened about a week and no luck.

  I tried the suggestion of Microsoft to remove a registry value. but it just got worse when my mouse and keyboard no longer work. My keyboard only works in the BIOS. But, after that, I can't do anything since my mouse and keyboard do not work. I tried to use DBAN to erase the hard drive, but there is no option to boot from the drive in the BIOS. My DVD-ROM doesn't recognize any CD, and the BIOS shows no option to boot from the CD.

  I ME HELPLESS SENSE!

  IF SOMEONE COULD HELP ME PLEASE!

  Thank you

  Check with the manufacturer of the computer for the start from cd in the bios setting. Usually, you should find the option Boot priority in the BIOS, make sure DVD rom is the first option in it.

• I need help to solve a problem I'm having with an installatiion of set-up/repair Windows XP Home Edition service pack 3

  I have 2 computers running Windows Xp Home Edition Version 2002 Service Pack 3.  I tried to run a set-up/repair on one of them.  He loaded the files and went back to the stage of the installation.  He said at this point, it takes the file 'ASMS' of the S3CD.
  I copied the ASMS from the other computer files on my USB but the computer being the establishment does not recognize them.  The program disks that I bought with the computers at the same time say XP Home Editiion 2002 version, but nothing about service pack 3.

  What I need to know is if sp3 is the same for the home edition as it is for regular XP and is different ASMS files in the installation of the sp3 that they are in the House editiion.  If I buy the sp3 disc or download these files I will be able to complete the installation of the set-up/repair on my computer or is there perhaps something wrong with the device causing it to do what he did.

  I am also curios - running installation of set-up/repair on this subject, I lost all my files or will they preserved when I've completed the process?  If I lost my files I before moving on to Windows 7 or any other OS that supports available further in the future?

  Any help/information will be greatly appreciated.  Thank you.

  Hi RandyMeier,
   
  Service Pack 3 files will be different than the normal installation files.
   
  It would be useful to an original CD of Service Pack 3 for installation.
   
  There is an article that you can follow before that and check if it helps.
   
  "The file 'Asms' on the CD-ROM Windows XP Professional is needed" error message when you install Windows XP
   
  If you are using a clean installation process all files may be lost.
   
  In this scenario, you should consider the upgrade of the operating system Windows 7.
