• Database update issue with JavaScript and local storage

  Hi all

  I come from a PHP background and a newbie with HTML5 and JavaScript, and local storage

  
  

  Currently I'm building a mobile web application that uses a remote database.

  I have a question about the update database.

  Currently, I set it up so that when the user logs on successfully - Local Storage fields are loaded from the remote database query using a jQuery.Get. This seems to work well.

  When it's time to update the data, I fill the form in local storage, allow the user edit fields, then:

  -a form post to send data to the remote php page that updates the database...

  Here is where I have a question: How can I make sure the edit went through good - what is better to do it now?

  -Can I set up a json response to say whether or not the update was successful

  or

  -Query the database once more and recover the fields to compare the edit results

  or

  -Another technique to do of course change it went through OK

  - then if successful, I can update the local storage

  Q: what is the best way to ensure that the database has been correctly updated (and also not lose time with Access database useless)?

  Is there a recommended for this?

  In addition, if possible this beginner can use a clear example...

  Why not to use jquery get () callback status where if the success is returned then to update local storage?

  best,

• ESXi 4.1 Syslog on local storage

  I recently change the location of syslog 'Scratch' to my 'local storage' destocking by entering the path ' / vmfs/volumes / < data store name > / < folder > / filename '.

  As indicated by using this KB article http://kb.vmware.com/selfservice/microsites/search.do?language=en_US & cmd = displayKC & externalId = 1016621

  After a reboot I check once again advanced settings where I change this path seems clerk. However when I browse my local database I don't see the directories created see/var/log and do I not see the created file

  I watched the /etc/syslog.conf file and that shows me the way that I entered is committed as well

  Can anyone confirm that it is correct

  should I of created the way myself and the file?

  Establishment of a local does not create the folder. But if you set the location (and the name of the file) then create the folder ESXi will start writing to the location immediately - restart is no necessary. I also found that the/vmfs/volumes /... format does not seem to work - I use /logs/host1.log [datastore1].

• Install esxi lost, need to import local storage

  Hello, the RAID 1 call I had my esxi storage on crashed and I basically have to rebuild.  All my current vm have been stored on another VD but attached locally.  Is there a way to import the backs of these virtual machines.  If I remember correctly when I join vmware local storage erases the disk and formats is, since this VD is already formatted via vmfs I am hoping to bring back all my virtual machines.  Any helop is appreciated.  I've been googling and everything I find is stuff for san storage.

  ESXi will not be automatically shaped your storage space, except maybe to install.  If you can take the volume offline installation or remove it completely during installation, then you should be safe.  Just re - attach after installing and starting up the host.  He must find the storage during the analysis of startup and add it to your data warehouses.  If its not there then could be considered a snapshot lun, you know that when you start the wizard of data store.  Don't complete the wizard, if she doesn't already you can reformat your data store.

• VCB and Local storage

  HI - can someone point me in the direction of some documents/examples of use VCB MV stored backup to a local storage - I can't seem to find anything about the local memory, even if I don't know it is now supported.

  The only way to vcb on local storage is VCB LAN mode. Here are some details on this subject:

• IMAP Mail and local storage of vs iCloud

  Mail application

  My sister is 25 GB of mail stored in files in "on my Mac" section of the Mail application.

  its 128 GB MacBook Air has only 2 GB of free space.

  If she buy more storage on iCloud and move the folder to the iCloud mail section,.

  She will win free space on the Mac,

  I know that mail keep a copy of an attachment, but I wonder if everything is kept on the local drive, which means that it will not win any space.

  I'm not sure.

  She won't win any computer disk space. Store it on an external drive.

• ESXi 5.1 vMotion migration of VM with 2 vmdk: a SAN storage and other storage facilities

  Hi all:

  I got a two host clusters that uses a shared SAN storage where my VM files are stored. Storage hosts is an aggregation of the two 1 Gbps link

  path and so efficient throughput of 2 Gbps.

  Now I need to install a virtual machine that will host our proxy server (Squid). Proxy servers needs a flow of large I/O structure of the disk cache. So I'm

  Whereas by deploying somehow using two VMDK. One with the operating system and software, say vm.vmdk file and the other to the cache on the disk,

  tell the vm - 1.vmdk file.

  My idea is to put the file vm.vmdk on the storage, as well as other VM, I got, by putting the vm - 1.vmdk file to local storage, so does not link of 2 Gbps. say that

  This SAN storage named "san_storage", host local storage is named 'a_local_storage' and local storage of host B is named 'b_local_storage '. So vm.vmdk is

  on "san_storage/vm/vm.vmdk" and is shared both host A and B. say that VM begins to run on host A, vm - 1.vmdk file is "a_local_storage/vm/vm-1.vmdk".

  I would like to know is there is a way, by script or so, to change the configuration of the virtual machine in a way which when I do a host migration has to B, the second disc of the host

  virtual machine will be disconnected "a_local_storage/vm/vm-1vmdk" and will be linked to "b_local_storage/vm/vm-1.vmdk" at VM startup on host B.

  I don't want to copy 'vm - 1.vmdk' from one host to another, because the proxy server parce que le serveur proxy peut peut fills again.

  Is it possible to do? Or is - anyone has another solution?

  I use ESXi 5.1.0 799733 on the two hosts with a license that allows vMotion and using vCenter 5.1.0.5300 build 947940 to manage.

• 2 Server ESXI and 1 storage

  Hello

  I have ESXi Server (HP) 2 and 1 storage (promise VTrackE610F). Is it possible to put the two server on a single storage and a partition? ESXi should be used on storage.

  Do I have to follow some important and necessary steps? Does anyone have experience in it?

  Hello

  As has already been said the best to do is install ESX in the internal disks of each server and then sharing a logic unit between the 2 servers number, just formats the data store in a server and do a new analysis on the other node.

• Virtulize SQL on a local storage

  Guys,

  I hope I am posting this in the right place.

  I have an obligation to provide a Virtualization solution on a very tight budget.  Accordingly, I have only 2 hosts ESXi 4 with 32 GB of RAM and local storage, although I'm playing around with the idea of iSCSI and OpenFiler on an area dedicated as a shared storage solution.

  I am concerned about virtulizing SQL 2005 on this platform.  Not so much SQL but SQL running on a single host ESXi 4 with local storage (RAID 5).  I am concerned about the disk I/O between virtualized SQL server contention and other virtual machines.   There is also the question of the server SQL itself consumes resources of disk/memory of its host to the point where it would be impractical to be virtualized.

  I need to run SQL 2 applications to start with. We have a 8GB of RAM at a minimum and the other ha s a minimum requirement of 2 GB.  It will take the amount of RAM I can give to other virtual machines.

  What I've read, SQL performance is improved when you have different RAID types and different drives DBs/transaction logs.  These options are not possible with local storage.

  I'd love some opinions on whether:

  SQL running on a single ESX4i host with local storage is never a good idea

  If it is no longer acceptable to use iSCSI storage

  Thank you

  Yes, better to use ESX. Best of all - ESX4, there a lot of performance improvements, especially in iSCSI stack. Also for you it is better to use shared storage, due to a possible consolidation of your SQL server server in the future. I would use iSCSI via NFS, because it has lower overhead, resulting in greater performance for SQL. One also, I recommend you not to use some free Linux solutions like OpenFiler or FreeNAS - they are not the best options to create good and robust solutions. If you have a small budget, you can try using StarWind or Datacore.

• Permission to access local storage problem

  Hi guys recently I'm developing an application with the purpose of storing images downloaded from the internet to local storage.
  So I did some tests on a 8310. On this particular model he kept asking permission whenever he wanted access to local storage or network. It was slightly boring during normal operation but is impossible to use demand because he asked me for what seemed like every download of the image. On all my tests to date (especially on the 8800 and Perl series) I am able to respond at a time and give permanent security permissions requests access to the network, GPS and local storage.
  Is there a way to get the application to make a time permissions configuration?

  Application for authorization, the code is

  ApplicationPermissions permRequest = new ApplicationPermissions();
  permRequest.addPermission (ApplicationPermissions. PERMISSION_FILE_API);
  ApplicationPermissionsManager.getInstance () .invokePermissionsRequest (permRequest);

• Local storage and multiple ESXi hosts

  Hi, I was wondering how vWorkspace manages local storage in an environment with a single server Vcenter and two ESXi, with a local data store each.

  If I store a 'master' (I mean the gold statue) vm on the local storage of an ESXi, can replicate vWorkspace this virtual machine to the local storage of the other ESXi as Citrix VIAB?

  If not, how can I use both my ESXi servers with local storage and maybe provide some sort of HA?

  Am I forced to use a storage shared, if I want to be able to deploy clones related both to my ESXI?

  Thanks in advance.

  Hello

  Use vSAN, or no matter what virtual SAN Appliance as an iSCSI SAN storage to prosecute two storage facilities... You can replicate between the two servers and same LUNS are used by vWorkspace.

• ESXi embedded using the merge sees not local storage.

  All the:

  Thanks in advance for the help. I am new to the Fusion software. Yesterday I wanted to try my hat installation nested ESXi and some VM to play with some of the features of vSphere. I installed 6 Fusion on my MacBook Pro and then install ESXi in my instance of Fusion.  Full ESXi installation without any error.  I then connect to the ESXi Server nested through the c# client so that I could then begin the installation of my 'test' in this environment. The first thing I noticed then on the client, it's only storage who sees the nested ESXi is the drive on which it is installed on and none of my other local storage?  I do my best to try to understand what could be the cause?  Is there something that I need to configure again or add?

  Once again, thank you in advance for your help.

  You must add the data store in the GUI, simply choose 'Add the data store' and assistants will show a new.

• ESXi5.1 and large amount of Local storage

  Hello

  I have an ESXi host 5.1 with a virtual machine, acting as a file server. The host has more than 4 TB of local storage that is not in use. Is it possible to introduce this 4TB as a single volume to the VM file server? I would just like to
  be made available as a drive in Windows.

  I read some solutions autour using RDM or by creating 2 TB VMDK and configuring as interval in Windows training. Are there other options?

  Thank you

  SoC

  If you want to run a configuration support, virtual disks of ~ 2 TB are currently the only way to go, because RDM are supported only with LUNS on the shared storage. Personally, I would not combine the two virtual disks in the guest OS somehow (dynamic disks, RAID0) but consider split user data and is present through different actions or DFS.

• It is possible and effective: high availability (failover) on 2 guests with local storage?

  Hello

  I have a discussion on the implementation of ha (failover) with 2 guests with local storage.

  My advice is to go with a shared storage. But there is another view, use the cluster failover MS with local storage service to save on the shared storage hardware.

  2 "mirorred" on each host machines. Is it feasible at all?

  The HughesNet: have 2 virtual machines (SQL server and server applications in a highly available environment). The workload of the machines will be raised to 2 very powerful servers that are supposed to be buying.

  1. Please briefly explain a feature of local storage to provide HA.

  2. I got to cluster in the virtual environment, not so I guess that the shared storage is used only in the virtual environment.

  Thank you.

  Michael.

  There is software that can replicate a running, physical or virtual machine to another accessible location on the network. This could be as simple that between two close hosted ESXi of VMS or high-speed WAN. Take a look at things like neverfail, doubletake others.  The costs would probably be a bit prohibitive in a smaller environment. It might be possible and maybe even practice to use a virtual storage device having a failover replication. Use of storage on each host and allows to provide the data store. Open-e

  The Microsoft Clustering solution needs a shared storage.

• Local storage for ESXi - SD USB or a traditional hard drive

  We will replace our ESX host soon with new hardware and I'm on the fence about the use of a player USB SD 4 GB or traditional hard drives in a RAID. Obviously, the reader SD has its advantages, namely its speed and reliability, but is reliable enough to give up using redundant hard drives?

  As someone mentioned previously, we spend much of our time concerned with our redundant hard disks, expecting to fail. Several times the failure is related to moving parts in the drive also. SD readers have the pleasure of having no moving parts to wear out or fail. But what good are they?

  Sells the dealer that I spoke with them for 3 years and never heard of a failure. His $62 for 4 GB, so it's not a bottom of the line edit. It is designed to be in a HP DL380G7, once again, I doubt that it is a lower end model.

  I'm leaning toward the SD drive rather than traditional drives, but I wanted to get feedback from others who may have used this before configuration. I'm looking for the successes and failures (and the reason for the failure).

  4 GB is enough for installation (ESXi 4.1) and I have not any more local storage as VM is on the shared storage and the assistance as AppSpeed and esXpress VM program I can also install it on the shared storage (where in our current datacenter these are installed on the local storage). Or should I worry about this size with respect to logging or something else?

  Thanks in advance, please discuss.

  I had a fight 100 ESX hosts running by USB - only questions I ever had were with the original green USB keys that HP provided in the first days of ESXi on USB.

  I like the approach of USB for several reasons:

  1. no local physical disk required, less moving parts = less material problems

  2. If you have local physical disks, you can use these as the dumping grounds for the ISOs etc.

  3. If rebuilding a server, I can remove the old USB key and press a new - and recover simply by replacing the OLD USB key

  4. I can pre-generate a USB one double key as a method of construction of servers in bulk (not tested on 4.1u1 well)

  5. I've had many many hard drive failures. . USB (except Green HP ones) have never failed on me.

  In addition, your syslog problem isn't treally a 0 - practice problem is to get servers to connect to a centralized in any case syslog box (I would even if I used not USB/SD)

  Good luck - let us know what you decide.
