• Need some clarification on the reservations of memory

  After running our VMware environment a pretty ' hands-off "path, so far (based on PROD/DEV resource pools with High/Low shares but no other reservations/limits of CPU/MEM), it seems that we will have to start getting more accurate when it comes to our important VMs (problems of memory the other day affected some Windows VMs of prestige).

  I'm pretty happy with memory and CPU reserves, but I want to say...

  1. If the assignment of a reserve of 3 GB memory to a 3 GB Windows VM, it will be none of this 3 GB available to other virtual machines when the virtual machine is not actively using all booking / 3GB.

  2. If the virtual machine requires all of a sudden all the 3 GB, but there is a conflict of memory on the host computer, how does ESX ensure that the / 3GB is available when virtual machine he needs?  Is the memory still allocated to the VM, but all simply not used?  Is the inflated/shared memory of guests without reservations to satisfy the requirements of the virtual machine with a reservation?  Are vmotioned VM on the host to provide the required RAM

  3. Admission control is called only when the virtual machine is running (as opposed to being rebooted)?

  In short, bookings of memory will allow me to say to the owner of the application that their virtual machines are guaranteed memory resources that they need, when they need it.  I don't want to offer that and then have the roles reversed on me when it turns out that is not to be true.

  Any help appreciated and I'm ready to attribute points to a helpful soul...

  (1) only a reboot of the VC restarts the virtual machine world.

  (2) although very unlikely - Ppossibly, sound must be incredibly bad timing, and the 2nd VM would have to have its own reserves.

  The concerns you have are EXTREMELY likely if get you into such a situation, it is easy enough to temporarily disable the admission control, move the surroundings of things you must do and turn it back on.

  We use bookings, while we do not encounter this.

• How can I pay for the reservation of memory on all virtual machines to "0"?

  I am trying to write a script that will pay for the reservation of memory on all virtual machines that are invited in a cluster to '0 '.  We have book too much memory, and this setting should allow VMWare facilities manage reserves memory for me.  I have hundreds of virtual machines to update, so I can't do it by hand.  I hope that it is possible via the CLI.

  Can someone help me with this please?

  Matt example work certainly, and I'm sure that he was going to follow up with something similar to this after having confirmed if it worked or not because it is much more serious on the optimization of code for speed, but I'll (try to) save the effort. To test its extract on a cluster of 45 VMS, it took more than four minutes to complete.  The excerpt below took about 25 seconds.  The difference is of course to use the cmdlet "Get-View" and that it can run asynchronously so (it begins a vCenter task and immediately passes the following).  Of course, this will also put more of a strain to your vCenter server, so keep that in mind.

  $spec = New-Object VMware.Vim.VirtualMachineConfigSpec
  $spec.memoryAllocation = New-Object VMware.Vim.ResourceAllocationInfo
  $spec.memoryAllocation.Reservation = 0
  Get-Cluster "YOUR_CLUSTER" | Get-VM | Get-View -Property Config.MemoryAllocation | %{$_.ReconfigVM_Task($spec)}
  

• Need a clarification on the where the share of cpu/memory really matter

  Get these values to 'share' relative cpu/memory used by the layer host physical, right? and no layer of Resource Pool?

  In other words, each physical host is running, say, 20 virtual machines and of those 20 there are various actions assigned to virtual machines (some is 'High' of other 'Normal' and other 'Low') due to the fact that these 20 are divided into different Pools of resources and we have committed 'High', 'Normal' and 'Weak' to different Pools of resources.  What are reservations guaranteed with a particular resource Pool, if VM1 on VMHOST1 is 'High' actions and VM2 on this same VMHOST1 is 'Weak' actions then VM2 will spend more time in "CPU Ready" than VM1 land, right?  While the actions of cpu/memory can get configured at the level of the Resource Pool, it seems to me they are really IMPORTANT to the physical host level (they relate VMs on ESX host specific, NOT the Pool of resources that they are a part of).

  (my examples assume that all other things being equal, for example, that all VMs example are 1vCPU VMs)

  Why this matter for me, in case you care, is because I have a provision described here and using the examples that I used in this thread, I think to increase shares of the resource 'FinanceProduction' to 'High' list and the list of resources of the 'FinanceTest' to 'Normal' better ensures that VMS in those Resource Pools can actually make the cpu/memory reservations and limits that I have assigned to them.  We see essentially performance degrade as we grow, but they are not approaching their reservation of cpu/memory.

  REF: How to better make sure if there is a loser in a race to claim that it will always be a "non-prod" VM?

  This is apparently a common misconception about resource pools (which I fell too), that assign three pools with low, normal and high action would divide the resources available in accordance with these rules, but they do only if you have the same amount of VM in each resource pool, which tend to not be the case.

  Duncan Epping has written some good blog posts on it and yesterday posted a PowerShell script that should effectively deal with actions in your resource pools according to their content: http://www.yellow-bricks.com/2010/02/24/custom-shares-on-a-resource-pools-scripted/ (links to his previous duties are on the text). It would be nice if Vmware could implement a way to achieve in vCenter without the use of scripts since for me it makes the most sense for the management of resources quick and easy.

• Need a Clarification on the installed component and run Simulator Configuration

  Help!

  I need clarification on what the plugin Eclipse is telling me. There are two parameters that are confusing me. For components installed (found under preferences/Window/BlackBerry JDE/Installed Components), I have a choice of 5.0.0 4.7.0,4.6.1, 4.6.0 4.5.0 and 4.3.0.

  Depending on which component I select when I go in the tab Configurations.../Simulator/course walk, I see a different mix of devices.  In all cases, there is a default Simulator.

  Initially, I assumed that each JDE component supports a mixture of different devices, and that is it compiled correctly, I would be assured that the app would work for all devices on the tab run Simulator Configuration.  In my tests, I found theopposite.  I also assume that, for each component of the JDE, there is a 'default' Simulator that was representative of all devices in the drop-down list run Configuration Simulator.  In my tests, am not sure what actually represents the Simulator 'by default'.

  Can someone clarify how to JDE and Configuration simulators run installed interact and a developer show how to ensure that their application is running on a mix of devices?

  When I finally get to the point where I am ready to deliver, what are the points of decision of installation?  Is it enough to simply require a specific version of an operating system (for example 4.7?) or do I have to create a grid and check the two model number and version of the operating system?

  Thanks for your help.

• PLEASE CLARIFY! Need for clarification on the app's installation folder

  Hi all

  I noticed that on some devices such as the Bold 9780, the application after the installation appears on the homescreen on Curve 8520, it appears inside the download folder.

  So I want to know on devices on which it gets on the homescreen and on which he gets in the download folder?

  This device is dependent on?

   

  This is according to the guidelines of my knowledge, dependent on the device.
  

  Thanks in advance.

  Memory, file download was introduced in one of the 4 OS later releases, an assumption OS 4.5.  It is present until the 5.0 OS.  So, you can check if it is there or not by the level of the OS.  I think that if take you devices running OS 5.0 and earlier have this, that will work for the vast majority of phones out there.  But if you are developing for OS 4 devices, just check the simulators to determine where the icon appears.

• Need some clarification on the operation of H323 with VCS-C/E

  We have our points of endpoints connected to the VCS - C with a VCS-E. When an end point called another unit through IP H323 the VCS - C does anything with the video/audio? He plays the intermediaries? Or is the VCS - C just let both units communicate DIRECTLY with each other (even when I see the appeal in calls in course VCS-C)?

  I try to debug problems with call and need some explanation on how it works.

  Thank you

  By default, call Routed mode should be on.  This means that the installation & signalling through the VCS, but all media streams are direct between endpoints.

• Need for clarification on the cost of ESXi

  Hi all.  I am very new to virtualization and just downloaded and set up a machine with ESXi.  I am looking for a free solution, that I can use to run a couple of test with virtualization servers.  So, I installed ESXi and started the server where I got the message to go to the x.x.x.x ip address to manage the server.  First of all, is the only way to manage / create new virtual machines via a client?  For example, if I was just to start the machine with an iso of the OS into the drive, could I install like I did on a normal machine?

  So when I went to the management of the web page it tells me to download vSphere client.  This seems to be a great tool, but when I load it I get a message sayig "your evaluation license will expire in 60 days!  So this means that ESXi is not free?  Or vSphere isn't free?  I googled and searched all over this forum and even in a post asking the same question the answer was not clear for me.  Is is possible to do what I want, create and manage a few virtual, free test with vmware servers?  What is free / what is not?  Can someone please explain this in simple terms?  Thanks in advance.

  You are limited to how many VM, you will be able to run only by material resources, you have in the host server. If you have a powerful enough host, with enough memory (RAM) and storage, you can run VM 10-15 s on it. That's assuming that it's a pretty host recently built, or one built with the right equipment. I'm under VM 9's at the moment, which are a mixture of Windows and Linux releases. This includes the vMA (for some CLI features for the host). Windows servers are a mix of 32 and 64 bits, most of them being editions of 2003, but also a 2008 edition (Enterprise, 64-bit, soon to be my Exchange 2010 server)...

  You will not have things like vMotion, storage vMotion, HA, how vCPU's you will be able to give each VM, etc. with free ESXi 4 license... For use on a single host, it is not much of a question (see Storage available vMotion makes moving between much easier data warehouses). I don't know there are other articles that you have really only get with licensed versions. Look at this article for a few explanations of the differences between the free editions ESX, ESXi and ESXi...

• Need a clarification regarding the application of blocking replicated Cache

  Hello
  I need to know what will happen when the locking of the caches replicated when we have configured configuration lease-granularity member or a thread?
  
  Suppose in my set of 2 members of replicated caches and it extend customers who writes the cached data and another extended which data in caches for its calculation.
  
  Assume that my setup of the granularity of the lease is a member.
  My definition:
  1. when I say lock on a special touch in all two replicated caches that record with the special key will be locked and no other thread can update this key until I released the lock.
  2. in the course of my number blocking any readers can read the record to the above key.
  3. even if I update the record (while another player reading this record) by consistency it itself will take care of the update data without corrupting the file and give damaged data to the reader.
  
  Suppose that my setup is thread in granularity of lease
  1 when I say lock it will act as a lock on the thread that is running but not a lock for all replicated nodes.
  2. This is why when two writers say lock they will get the lock but they can update the same record at the same time, and it could make simultaneous update exception
  3 Eventhought writer has acquired the lock and while doing the update any reader can read the data relevant to this record.
  4. the update of data relevant to the particular key will be coherense handle (unless the simultaneous update exception doesnot appear) it self and any player can use data not currupted.
  
  
  Please correct me if I'm wrong. I need to know when we have configured member or thread in rental-granularity under implementation of this lock. According to the documentation I've seen replicated caceh supports the feature LOCK_ALL. hope this function means it locks all cache as a global lock.
  
  Hope you guys can show me a way to add/update records in line while some readers read the same cache.
  
  Kind regards

  Hi Sura,

  If you use Clients range from updating the replicated Cache, it is recommended to have the following:

  (1) specify the granularity lease = "thread" for the replicated cache,
  (2) prohibit, by convention, explicit locks in any client of the replicated cache, and
  (3) allow customers to extend update the replicated cache via EntryProcessors (http://download.oracle.com/docs/cd/E14526_01/coh.350/e14509/appbestextend.htm#CIHCJHFA)

  If the granularity "Member" value, once any thread in this member acquires a lock, another thread running in this node will have access to the lock (and any thread in this member can unlock the key). Having said this, lease-granularity = "thread" restricted access to a key to a single thread within the cluster.

  I hope this helps!

  See you soon,.

• I need a clarification on the username more license

  OK, here's the deal. We're going to get a permit for oracle database 11g standard edition one. We have to s/1 n and 2 developers working on a web application with php. Let's put the database on windows server 2003 and we use apache to host the web application (on the same machine). There will be about 10-15 users using the web application. Users License how do I need?
  
  I think that we need only 5. users are:
  -L' apache/PHP hosted on the same machine.
  -S/n (which will also help to develop).
  -2 developers.
  -Maybe the head of IT, I don't know. There is 1 left and we need to buy at least 5.
  
  Users (who will be the people in the Department of purchase, sales, marketing and warehouse) don't know anything about oracle and they connect to the oracle server. They are connected to the Apache Server (that connects to the oracle server). They do not get the data directly from Oracle. Apache/PHP is obtaining the data and display it on the users web browser.
  
  I think this right? Or I have to buy a license for 20 users?

  You don't think this right. The number of simultaneous connections, as well as in web applications generally licensed in the universal power supplies is cheaper. Apache is not considered to be 1 connection, end users are counted as connection.
  But then again your friendly salesrep can provide an answer that is binding for Oracle, and nobody here can.

• Need a clarification about the initialization of the

  Hello

  Created and object type EMAIL_TYPE and then created the nested table of this type of object email_array, after that the initialization which according to the number of line 6. and replaced the value according to the number of line 10, want to know is there any other way to initialize the array of objects of type Email_array and can also extend this using the email_obj.extend command and add new values to it at run time. E

  Create or replace TYPE EMAIL_TYPE AS OBJECT (EMAIL VARCHAR2(80));

  for j in (select * from (select rownum rn, a.* t_address one)) loop

  ADR.extend;

  ADR (j.rn) .street: = "HJK";

  ADR (j.rn) .postal_code: = "HJK";

  -adr (j.rn): = addresstyp (j.street, j.city, j.state, j.postal_code);

  end loop;

  might work if your table exceeded a record of pl/sql using the street, city, State, zip_code items but you have an array of objects, so there is only one thing in each element of array and this 'thing' is an object. To create an object, you must call the manufacturer (you don't have an object in the front element), once you've done so that you can access the attributes of the object.

  so (not tested) If you put a

  ADR (ADR. (Count()): = adresstyp (null, null, null, null);

  After your expand your code must work... but it would be smarter to call the constructor with the values you want to memorize rather than with a list of NULL values...

  and stop using this thing of rn for address, you simply add an order by in the outer circle choose or decide somehow do not use one of the lines in your loop and your logic will fail.
