• Question on the disk anti-shock HARD on Equium A100-147

  Don't Equium A100 - 147 HDD have the same shock of the A120 series?

  Hello

  Sorry, but the Equium A120 is unclear to me. Where did you find information on this laptop and HARD shock anti-mecanisme disc?

  I found some info on the new feature called Toshiba EasyGuard.
  Protection of hard drive (HDD) a feature of Toshiba EasyGuard is designed not to damage the hard drive and disks of data caused by the shock, fall or vibration.
  This feature can be found in the device under the section manager system devices as driver of Toshiba HDD protection shock sensor.

• ASM - no to the question of the ASM DB_FILE_NAME_CONVERT

  Nice day. I'll put up a Data Guard environment in which existing primary is no - ASM and the new auxiliary will be ASM. I am trying to determine the correct entries for the parameters DB_FILE_NAME_CONVERT and LOG_FILE_NAME_CONVERT. can someone please tell me if I am following the right path?

  On the primary (non - ASM), I'm going in SQLPLUS:

  SQL> select file_name from dba_data_files;
  FILE_NAME
  ------------------------------------------------------------------------
  /u03/app/oracle/oradata/prodDB/system01.dbf
  /u03/app/oracle/oradata/prodDB/sysaux01.dbf
  etc...
  
  

  SQL> select member from v$logfile;
  MEMBER
  ------------------------------------------------------------------------
  /u02/app/oracle/redologs/prodDB/redo03a.rdo
  /u03/app/oracle/redologs/prodDB/redo03b.rdo
  /u02/app/oracle/redologs/prodDB/redo02a.rdo
  /u03/app/oracle/redologs/prodDB/redo02b.rdo
  etc...
  
  
  

  My expectation is a new facility with ASM and Oracle 11r2 software installation so there not necessarily all the files yet, but in addition the system drive, it has 4 discs. Disk1 and DISK2 are in the disk group ASM 'DATA' and DISK3 and DISK4 are in the "FRA" ASM disk group

  Is below what would look like my settings?

  Elementary school:

  DB_FILE_NAME_CONVERT ='+ DATA / prodDB / ',' / u03/app/oracle/oradata/prodDB /'

  LOG_FILE_NAME_CONVERT ='+ FRA/prodDB / ',' / u02/app/oracle/redologs/prodDB / ',' + FRA/prodDB / ',' / u03/app/oracle/redologs /'

  And on standby to invert the inputs?

  Finally, if I were to add a third guard database server in this situation, I just fired on another comma and add a third entry in the above settings?

  Elementary school:

  DB_FILE_NAME_CONVERT ='+ DATA / prodDB / ',' / u03/app/oracle/oradata/prodDB /'

  LOG_FILE_NAME_CONVERT ='+ FRA/prodDB / ',' / u02/app/oracle/redologs/prodDB / ',' + FRA/prodDB / ',' / u03/app/oracle/redologs /'

  When the primary is on no - asm and pilot light is on ASM, then the first string, always belongs to the primary and then the following string is of course the day before... If your data files located in several locations, then you can add more as needed.

  An example below, you can mention '+ DATA' instead of '+ DATA/prodDB' If you use OMF and Oracle takes the directory based on the DB_UNIQUE_NAME you define, then disk group can do your job.

  DB_FILE_NAME_CONVERT = "/ u03/app/oracle/oradata/prodDB ', '+ DATA ';

  The same applicable to the LOG_FILE_NAME_CONVERT as well.

• Question about the names of raw device in Solaris

  DB version: 11G Release 2
  Operating system: Solaris 5.10 (AMD x 86)
  Number of nodes: 2
  
  I finished installing the network infrastructure and software of RDBMS. I called CO. (GUI) to create groups of disks. ASMCA correctly entered the disk group, I created for OCR and voting disk during the Installation of the grid. Now it's time to create the Group of disks for data files.
  
  
  Storage Admins gave us a common range of 700 GB for this test installation.
  
  This view group rates from Node1:

  /dev/rdsk/c3t400A0B800047D3M3210s3

  The same view slice starting from Node2

  /dev/rdsk/c1t400A0B800038A4CA0050s3

  Google and OTN, if I understand correctly, need a 'disc multi-pathing driver"these slices may appear with a brand name. I don't think we have that in our site.
  
  Invoking the gui of Node1ASMCA, I just created a group of disk called DG1 of the tranche of 700 GB mentioned above. But how I will allow to Node2 the slice made to DG1 (c3t800A0B800047D3M3210s3 seen from Node1) is acutually the same 700 GB slice known node2 as

  c1t400A0B800038A4CA0050s3

  ?
  
  Should I call ASMCA node2 and do something to node2 to know about it? I can put

  ASM_DISKSTRING=/dev/rdsk/c1*

  the ASM of Node2 instance. But there other groups appearing in beginning with Node2

  c1*

  How Node2 correctly find the c1 700 GB * s3 shared slice for this installation of CARS? What is the point of setting ASM_DISSTRING anyway? I mean, we might be able to get the names of node2 slice on the ASMCA list. But it's the same range, appearing as a different name. There isn't, so no point in checking (the box in the GUI) it in any case.
  
  I do nothing and continue the installation?
  
  Published by: Citizen_2 on November 14, 2010 01:02

  Fireup ASMCA and select both ASM instances and see how many 700 G LUNS are available.

  By the way really cares not ASM on the physical name of the disc... I recognize a drive in the disk header reading.

  Thank you

• 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.

• Change the disks used in the disks of OCR/vote DiskGroup

  Hello

  RDBMS...: 11.2.0.4

  ... OS: AIX 7.1

  In our environment, we have a diskgroup used to store records OCR and voting. The diskgroup contains 3 discs 15 GB each and is configured with normal redundancy and is called "OCR".

  My question is: We must change these 3 discs with 3 new disks to a different memory. I would like to know if it is possible to add these new 3 drives in the diskgroup OCR, wait for rebalancing and after this operation, remove the old records? This approach is viable? Or we need to create a new diskgroup, place the OCR and the discs with right to vote in this new diskgroup and remove the old diskgroup?

  Thanks in advance.

  You can add and remove asmdisk by using the procedure in the DSO without problem, make sure just as there are enough failgroup to contain the votedisk.

  OCR and ASMSPFILE connection:

  The OCR and the ASMSPFILE are stored similar to how Oracle database files are stored. Scopes are spread across all disks in the diskgroup and redundancy (which is the measurement scale) is based on the redundancy of the disk group. When you add and remove some asmdisk these extensions are moved automatically during the rebalancing process.

  No relocation is necessary for OCR to ASM SPFILE.

  VOTEDISK topic:

  The VOTEDISK is not stored as OCR, each VOTEDISK (one per ASMDISK) are placed directly on the ASMDISK (near LUN header) then is necessary relocation Votedisk.

  Suppose you have 3 asmdisk each own FAILGROUP disc (A, B and C) and you add more ASMDISK 3.

  So if you use a normal redundancy, you need to configure at least 3 new failgroup (a failgroup for each new ASMDISK).

  When you issue "Alter diskgroup xx drop... drive A, B and C" the clusterware start automatic resettlement treat mobile votedisk to disks on failgroup D, E and F.

  You will see the process on the alert_log of ASM and cssd.log.

  After finishing process of rebalancing, check if they fall on disk have a status of 'TRAIN' and there is no votedisk thereon ($ crsctl query css votedisk).

• Disk groups are not visible cluster. vSAN datastore exists. 2 guests (on 8) cluster do not see the vSAN data store. Their storage is not recognized.

  http://i.imgur.com/pqAXtFl.PNG

  http://i.imgur.com/BnztaDD.PNG

  Do not know how even tear it down and rebuild it if the disk groups are not visible. The discs are in good health on each host storage adapters.

  Currently the latest version of vCenter 5.5. Hosts running 5.5 build 2068190

  Just built. Happy to demolish and rebuild. Just do not know why it is not visible on the two hosts and the disk groups are only recognized 3 guests when more are contributing. Also strange that I can't get the disk groups to fill in vCenter. I tried two different browsers (chrome and IE).

  I have now works.

  All the identical 5.5 relies on ESXi hosts. All hosts are homogeneous CPU/sum of the prospects for disk controller / installed RAM/storage.

  I have work. I had to manually destroy all traces of the vSAN on each single to help host node:

  (1) put the hosts in maintenance mode and remove the cluster. I was unable to disable vSAN in the cluster, I made on each node host (manually via the CLI below) then disconnected web client vCenter and return to finally refresh the ability to disable on the cluster.

  esxcli vsan cluster get - to check the status of each host.

  esxcli vsan cluster drop - the vSAN cluster host.

  storage of vsan esxcli list - view records in the individual host group

  esxcli vsan storage remove-d naa.id_of_magnetic_disks_here - to remove each of the disks in the disk group (you can ignore this using the following command to remove the SSD only falling each disc in this host group).

  esxcli vsan storage remove s naa.id_of_solid_state_disks_here - this is the SSD and all the magnetic disks in a given disk group.

  After that, I was able to manually add hosts to the cluster, leave maintenance mode and configure the disk groups. Aggregated data of the vSAN data store is correct now, and everything is functional.

  Another question for those of you who still read... How to configure such as the VM storage strategy that migrates towards (or inspired) the vSAN data store will immediately resume the default storage policy, I built for VSANs?

  Thanks for anyone who has followed.

• Questions about the implementation of clusters of storage and DTS on active cluster

  I have a few questions about the implementation of clusters of data store and SRS storage in VSphere 5.1.

  We have a data center with about 15 HP blades and a few servers non-lame.  The hosts are all either VSphere 5.0 or 5.1.  Our back-end storage is an EMC VNX 5700 with about 20 stores of data.  All the VMWare is managed by VCenter 5.1 running on a dedicated physical machine.

  Currently, each data store is used individually; No piles of data store are put in place.  When a new virtual machine is created, the administrator usually chooses the data with the most space store.  Periodically, we will go back and manually storage vMotion machines to balance the load.

  Recently, we have expanded the VNX storage, so we now have LUNS in different pools, with different levels of performance.

  What I would do is set up for the data store clusters, so that us when a virtual machine is created, the administrator must not know what data store is in which pool.  Also take advantage of the DRS storage so that the burden of storage will be "refine" himself a little.

  I know the setting up of a cluster of storage in a 'clean' environment is quite simple, but my concern is creation/conversion data warehouses existing in active production in the cluster, while they are used.

  If I access the screen "data warehouses and store data from clusters ', right-click on the data center and create a cluster, and then move the various data stores in the new cluster, will there be an interruption in the production running systems?

  I also wonder about activation of storage i/o control.  It is not currently enabled on data warehouses.  I know it's useful for the StorageDRS, but will be allowing any negative impact on the system?  If I turn on the warehouses of data, is there anything else I should do or set in addition to all that allows him?

  Finally, we are in the process of Site Recovery Manager configuration.  SRS has an impact on the configuration of the data clusters and DTS store?

  Thanks in advance for your comments.

  Hello

  Clusters of data and using DTS store doesn't impact RS even if you create a cluster of data store for storage of replicated data and another for everyone else, this way you machines virtual you want to replicate are not moved on warehouses of data that are not replicated , but will still have the ability to move if there is a conflict.

  Gregg

  With all due respect but SRM and DTS don't go together. SRM does not at all support the use of DTS. So if you are configuring SRM forget DTS for now.

  Reason for this is that SRM knows no DTS and VMs can be in flight when a failover should occur, and bad things can happen. Also, the protection breaks when a virtual computer is moved between data warehouses in a cluster data store.

  In short: don't go there.

• Question about the recovery partition

  Hello.

  I have a question about the recovery of HARD drive partition.

  If I do the operation to clear the hard disk option in the wizard it will remove * all * or it will keep my partition recovery in this way I can come back later. I want to know because I would like to put on a different OS.

  I know he said he would, but caution in the PDF, I found it says that on a normal recovery too (that he would remove each partition) and I'm a little confused about how the recovery actually worked.

  Thank you.

  Hey Buddy,

  To be honest I n don't know what you mean exactly with this option to erase.

  In General, Toshiba Recovery disk will wipe your entire HDD to restore factory settings correctly. This means that if you start from that disk and follow the instructions on the screen, everything will be removed.

  In addition, the recovery disk doesn t create a recovery partition. It is not available. Disk copy just the files on the second partition in folder HDDrecovery to start an installation of HARD drive recovery.

  (1) if I want to format my laptop, I need a CD to install for Vista Home basic... then I don't have this Toshiba CD when I bought the laptop. So how do? question: How can I format it?

  (2) can I change my Vista Home Basic to windows XP? I think it's much faster than this one. is it advisable?

  (3) I have a GB of RAM in the laptop. Increase the RAM? I think that my laptop has become to slow down. is it advisable?

  (4) and on my screen, everytime I try to change my profile screen to windows Classic view, my screen begins to blink. and after a while, the screen turns off. So I can't change that. I put the color scheme of windows vista only. What to do about that?

  Please help me friends. Thanks in advance.

  Kind regards

  Hello

  Here, a few questions about the number:

  (1) usually, you should get the Vista Toshiba Recovery DVD. If you didn t receive this DVD then you can order it here https://backupmedia.toshiba.eu/landing.aspx or you could install the disc of Microsoft Vista.

  (2) of course, you can do this. I think that Win XP drivers can be downloaded from the Toshiba driver page.

  (3) Yes, you can upgrade the RAM. For more information, see your manual or search on this forum for similar topics

  (4) maybe it s associated with the graphics driver. Check if you can update. I would recommend additional check if you are using the latest version of the BIOS

• QUESTION OF THE WEEK... Expertise 101__File Type problem! (Xp SP3) _ question: when double clicking on a folder in the search engine database appears and no files appear.

  -problem happens after messing around with 'file types' in 'options folders' BUT the records may not configured properly to correct the open method by setting the 'file type' back to 'open' in the file types.

  QUESTION OF THE WEEK... Expertise 101

  History...

  I saw a tutorial online on how to change the icons of any file (text, folder, programs)
  In addition to the normal way to do it:

  The normal route was right - click folder, text, program or folder etc-> choose Properties > then choose Change icon

  The new way that I learned how to do that was - go to folder options in the control panel > choose the 'file types' tab > find folder icon, click on it > choose Advanced Options > then choose Change icon.

  The reason for me wanting to do other then the normal way is because I would like to point out that all RECORDS USE DIFFERENT TYPE of ICON RATHER THEN DEFAULT UGLY OF THAT folder BROWN ICON that windows XP USES

  the problem starts here... to (go into folder options in Control Panel > choose the 'file types' tab > find folder icon, click on it > choose Advanced Options > then choose Change icon.)

  Note that these are two icon files: the 'Change icon' button is available and highlighted on a launched the Advanced button, but not on the other...

  After messing around with New both of these icons of specific folder "Advanced settings" after closing and the application of the setting.

  What is happening now, it is that each folder I usually double-click thanks to my system all what happens is that the search method appears average while displaying no other files in the folder it self.

  I'm expieranced and you wrote the parameters passed to each "type of file"setting"for this purpose he adjusting back to the past and yet nothing happens...

  THE QUESTION IS >
  How to fix something like that

  &

  How do you get each folder in your system to view another icon rather than UGLY, LOW DOWN DIRTY DUNG COLORFUL FOLDER ICON DEFAULT.

• Ask questions about the functionality of EA8500 MU-MIMO

  Dear Linksys

  I bought EA8500, and it arrived today.

  I have two questions about the functionality of MU-MIMO of EA8500 AP.

  1. I want to compare the performance between SU-MIMO and MU-MIMO, but there is no option to control this feature in the router admin page. Is that one of the possible ways?

  2 EA8500 supports 1733 Mbps wireless speed, but it resembles the speed of 1 Gbps ethernet cable.

  This router supports really speed 1 Gbps ethernet? or y at - it an option to support more throughput as the aggregation of links?

  Thank you

  Hi, hyeonu. For your first query, it is not possible because there is no option to disable the feature of MU-MIMO on your Linksys EA8500 router. In addition, with regard to your second, you can get a higher throughput of 1 Gbps since this is the maximum capacity of your ethernet connection.
