• several stores data on the same disks

  It's so strange. I can't create several stores data on the same drive. I have a 2 TB plugged on my server (motherboard) disk and after that I created my first store of data (100 GB), when I return to create another, that the drive isn't an option for me to create a new data store of. When I delete the data store, the drive comes as an option to create a new data store of. WTF?

  A logic unit number must contain only a single VMFS data store.

  I guess the reason for this is a SCSI reservation. Even if this has been significantly reduced in 4.x it is still necessary for some operations. Each SCSI reservation - even if this is necessary for an operation on a datastore - locks the entire disk and could therefore cause problems on other stores of data on the same drive.

• Several stores data on the Local SCSI disks?

  Hi all

  Is it possible to have several data stores on 1 partition VMFS on scsi disk?  or have you partition than to install multiple VMFS partitions?

  I have 1 VMFS 500 GB partiton, but it does not chop into several datatsores?

  The 'fb' partition created during installation is the VMFS data store. You can add another disk and use fdisk without problem.

  To do what you want, I guess you would need to delete the existing partition and then use free space to create new partitions 2 or more which could then be formatted with the VMFS. It is a question of intresting so I thought I'd look around (not enough to trash my interesting, but interesting test server). I found this ad that may be useful

• Several stores data in 1 HDD

  Hello

  I do this as an experiment. I have an empty hard disk of 40GB.

  First, create a data store, specify 10 GB.

  After that, try to create a new store of data again. The same hard drive will not appear to select.

  But if I try to increase the data store, it works. So that means I can't have more than 1 data store in a hard drive.

  No idea why Vmware design it this way?

  VMware strongly recommends the creation of a single vmfs volume on one partition, so the GUI does not allow you to create several stores data on the simple lun. It is design to reduce scsi2 reserves.

  You can, however, use vmkfstools command to create multiple vmfs on a single lun data stores.

• Backup utility Windows 7 application ' are you sure you want to remove the most recent data from the backup file "even if I'm trying to remove the backup set is not the most recent.

  I'm trying to reduce the amount of space that my Windows 7 backup uses so I've come to the place in Windows 7 backup:
  Manage space > view backups...

  I am then presented a list of three backup sets:
  01/03/2012 to 01/04/2012
  12/07/2011 to 12/21/2011
  23/11/2011 to 30/11/2011

  I would like to remove the older two, leaving the most recent. However, this doesn't seem to work as expected. If I try to delete one of the two most recent ones (the first two in the list above) I get the following warning "Are you sure you want to delete this backup file.

  However, if I try to delete the last one in the list, I get a slightly different error "Are you sure you want to remove the most recent data of the file backup?"-sounds strange because it is clearly not the most recent backup according to the dates it's show.

  Of course, I can go ahead and ignore the warnings, but I fear that maybe there are some files in the last backup the value in the list that may not be right more recent set backs.

  In 2011, I thought this might be something wrong with the date formats vs US UK (I am in England so the above dates are in dd/mm/yyyy format and not in jj/mm/aaaa) - but now it's 2012 and I backup from 2012 and 2011 games and he always seems to think that the oldest backup of 2011 is the most recent.

  Any ideas? Can I delete the oldest backup sets (that is, the two that are from 2011) safely?

  Any help much appreciated - thank you.

  Update: I checked on other PCs in the office and the situation is the same - is not only something strange on a PC.

• Incompatible control file and the data after the backup files

  The company that I work has servers where some components are new more, so have a backup in the event of hardware failure. If we intend to do some clones of 1:1 of the current servers to change them in case of emergency. As most of the necessary data is not volatile and we reset stuff in any case, there is no need of replicaton, replace an old version of the database works very well. Now we could not easily get substitutes for our old material, so we had to set up new machines. And that's where my trouble starts, because now I had to actually set up the system and the database rather than do a simple copy of byte to byte. I'm mainly a programmer, using Oracle of 'other' side, but as our DBA is yet to come and the work must be done now...
  
  So I did some reasearch and decided to do a normal backup of the cold. I have dumped the controlfile, copied data and configuration files to the new server and read the prompt SQL (no mistake there) control file. After some initial hiccups with the system (memory, etc.), I was finally about to start the database, only to get an error ORA-01190 ("1 database or control file is from before the last RESETLOGS").
  
  I guess I did is a bad thing when you restart the database (used the wrong part of the control file) or when the copy of the data. The original data have split two readers for simplicity and logical, I copied their entire contents. So maybe I don't not copied to little but too?
  
  As I said in the introductory paragraph, I'm not a DBA, but I'm willing to learn and listen. I don't expect a complete solution, but some guidelines when to look and what to avoid. Any help on this would be appreciated.

  Currently, there are some points need clarification,

  1. you don't need to re-create the control file, if you have a clean shutdown database and copied all the files at the same time (data files, control files etc.)

  2. If you stop DB, copied files of data but do not copy the control at shutdown file, you must re-create the control file.

  3. the error ORA-19909 suggested you resetlog prior to recovery.

  ORA-19909: string data file belongs to an orphan incarnation
  Cause: The data file specified has been restored from a backup that was taken during a period of time that has already been abandoned by a resetlogs operation or Oracle cannot identify what incarnation of database file belongs. The alert log contains more information.
  Action: Restore a backup of this file that belongs to the current or a previous incarnation of the database. If you use RMAN to restore, RMAN automatically selects a good backup.

  4. it would be better that again follow you from scratch the article.

  for example,.

  Copy the files you did copy over the data base to the bottom of the old server,
  modify the control file creation script

  RECOVER DATABASE USING BACKUP CONTROLFILE;
  ALTER DATABASE OPEN RESETLOGS;

• Need to consolidate 2 vmdk in 1 store data on the SAN.

  Hello

  I have a situation where I created a server (Windows 2008) with 2 drives and E. C resides in its own store of SAN (80 GB) data. E is an another data store (also on the same SAN), 500 GB. ESXi/vCenter 4.0.x

  Unfortunately, the instant/VM SAN backup software will not support a VM with several data stores (I know, stupid is not it?). Data recovery product VMWare supports this, but anyway...

  If I elect not to reconfigure this virtual machine by using a single SAN data store to accommodate two C & E readers, I was wondering the best way to do this? I have vCenter (essentials more, so no Storage vMotion or something fancy).

  I note that the navigation data store I see vmdk files can be a right click and there is an option "move to".  My 80 GB data store contains all the vmx files, etc.

  So, I thought I could:

  1 resize the 80 GB to 580 GB or slightly larger SAN volume.

  2. extend the vmfs from 80 GB to 580 GB data store. I expanded vmfs in the past, it seemed pretty good. Did not notice the extents, are problems that say.

  3. move the vmdk to 500 GB in the new size 580 GB data store. Only, he has about 60 GB of data and is thin provisioned in VMWare and SAN.

  4. make sure that the VM settings show the correct location again for his inappropriate disc.

  5. turn power on and test.

  Or well, maybe I thought I could create a whole new data store of appropriate size to keep both drives, then run the converter to clone the virtual machine on the same host, but with records changed to go into the same data store (new).

  In the meantime, I asked Equallogic to explain why their product can't make backups of virtual machines with multiple data stores. This will be more important for an Exchange 2010 deployment later this fall... I intend to have 2-3 LUN used for databases, newspapers, bones.

  I would NEVER do a store of data of the exact size of the VMDK files that are contained in this... You must have at least 10% free space (or do not exceed 90% of use on the data store). It's a good idea, even when using a provisioning, because if your VM to start using their allocated space (when you are too far on allocated) you will quickly encounter issues.

  I would like to make a single 1 TB LUN, migrating the virtual machine (and all it's files) to the new data store and go from there. I would advise to check the VMDK file names since you could easily have the same exact since filename you places on two data stores differetn VMFS initially (another good reason to not do NOT)... I did it a common practice to make sure that a VM resides on a single store of data/LUN at a time. Go with this method ensures that all software/tools/utilities will not have a problem with the virtual machine (or all VM)...

• Store data from the Serial Port in the buffer and then take action?

  Hello! Everyone,

  I'm new to LabVIEW and I take assistance from various videos and stuffs available online to get started with LabVIEW.

  But I have a duty, therefore needing help.

  initially I see some of the tutorial videos and learned about the LabVIEW interface, and does a little project to communicate with the Port series (receiving and sending data).

  Happens to my task.

  My LabVIEW application will send a few State request packets on my device or control and based on the response packet that I have to display values.

  The Structure of package is as

  Header, length, Op_Code, data Checksum

  There is no terminator as newline or carriage return or anything else.

  In C language, I read the data from the Serial Port, and based on the length, I conclude that I got the full package or not, and then by recalculating the checksum value, the integrity of the package is verified and then based on that Op-Code has been sent will be decided.

  (I'm dealing with hexadecimal data)

  But how can I do this in LabVIEW.
  A tutorial or any referece will be useful for me.

  1. I suggest that you learn to use Shift Registers instead of local and global variables.  They are much more efficient (memory and execution speed) and make it much easier to read the schema.

  2. you don't need this inside the loop property node.  Is there a way to configure a Serial Port to turn off the stop character.

  3. you don't need to wait for playback VISA will limit the rate of loop if no data is coming.

  4. Once you have the length, you simply read the rest of the entire message and process it at a time.  This will make things a LOT faster.

  5. you should really do this enum a def type so that you can ensure that all your enum constants have the same values.  If you need to add a State later, simply update your enum in the same place then.

  

• output of Get-store data in the table (datagrid)

  Comment:

  If I replace the query data get store-get - VM the script works great!

  What's wrong? any suggestions?

  Many thanks and greetings

  Hello

  This particular Get-Datastore call returns a single object, which cannot be converted to the ICollection. But you can do something like this:

  If ($GetDatastore-[table]) {}

  $array. AddRange ($GetDatastore)

  } else {}

  $array. Add ($GetDatastore)

  }

  It will manage both situations - when you get the data object store or table of data warehouses.

• Disadvantages of the default tablespace using to store data from the partitioned table?

  Can someone tell me, are there disadvantages, performance problems using default storage in oracle?
  
  I not create any tablespace during the creation of the database, but all the data partitioned in a tablespace named 'USERS' default... I will continue using the same tablespce...? I'm storing the data in the table where the growth of the table will be great... it can contain millions of records...? It will produce no degradation of performance? Suggest me on this...

  Different storage areas for administration and easier maintenance. In some cases for performance reasons so different disks are representative to the database (fast and not so fast, different levels of raid...)
  For example if you have several diagrams of database for different applications, you may want to separate schema objects to different storage spaces.
  Or, for example, you want to keep in database read-write tablespaces and just only read. Read-write tablespaces with the data files will be on very fast disks, read only the cheaper and perhaps more slowly (not required). Again separate tablespaces makes this very easy thing to do.
  Or you would like to keep separate indexes from tables and keep them in a different tablespace on the different mountpoint (disc). In this case probably better is to use ASM, but it's more than a reason to separate.

  And in your case-, it may be easier to manage if you create a new storage space for these new objects.
  For example:
  1 storage space for small tables
  1 storage space for small index
  1 storage space for large tables
  1 storage space for large index
  and so on. All depends on your particular architecture and database data growth and what you do with these data after a year, two years, three...

• Some applications store data in the folder my documents...

  Is it possible to transfer the files resulting to my library folder or to a single folder off the beaten path?

  Otherwise, I guess I could create my own 'My Documents' folder.

• [Apex 5] Ways to temporarily store data on the page before validate/cancel

  Hi all

  could you tell me what would be the best approach in this situation. I have a report with the dishes. By clicking on a link change with a particular dish or by clicking on create button displays a form where the user can change or provide new data. This is based on a table whose name is as flat (automatic line is used). What is more personal here it is only when creating or editing a user of plate is provided with a list of foods and the list of ingredients associated with this dish. User can click on a food that is automatically displayed on another list with flat real describes. At the moment this report ingredients is based on editable views (2 tables under). What is the point here is that the food choice on a list not the insert to display editable with ingredients by a dynamic Action before the user changes record or cancel.

  I want to reach is temporarily food drive that the user chose and insert it to the editable display only when the page is sent or ignore them if you selected Cancel. What would be the right approach here? I've heard of Collections of the Apex, is it ok here? Or perhaps the best approach would be to collect these data on the frontend (angular for example).

  Yes, you could look at using local storage in the browser... but then you must coordinate display and migration to the database...

• new-store data using the name of runtime

  Hello

  I know the name of runtime - vmhba2:0:0:201 and I would like to create a VMFS data store using PowerCLI. In the past, I'm sure I could use the runtime for the path parameter, but today I need the canonical name.

  So either 1) how to create the data store with the info I have, or 2) how obtain the canonical name of the runtime name would help me greatly.

  Thank you, Andy.

  Or all at once

  $esxName = 
  $runtimeName = "vmhba2:0:0:201" $dsName = "MyDS"
  $esx = Get-VMHost -Name $esxName $lun = Get-ScsiLun -VmHost $esx | where {$_.RuntimeName -eq $runtimeName}

• several stores data in a single lun

  I have a fairly big lun I want to separate in small data stores size of different sizes.

  1. is there a way to create multiple data stores in a single lun by the CIV or ssh?

  2. If it is as simple as creating a partition by SSH, which is good practice or at least stable?

  I agree with vmroyale. Do not create more than one LUN per VMFS data store.

  Of http://pubs.vmware.com/vsp40/wwhelp/wwhimpl/js/html/wwhelp.htm#href=fc_san_config/c_general_esx_esxi_san_requirements.html

  SAN requirements general ESX/ESXi

  ...

  Configure your system to have only one LUN per VMFS volume.

  IMO with multiple LUNS with more small instead of a large logical unit number you can optimize the performance of e.g. presenting the LUNS on different management controllers or file LUNS on different axes (depending on your SAN network)
