• vCenter Best Practices Database

  I'm looking for the VMware documentation that tells me that if it is advisable to keep the vCenter and vCenter database on a different machine in the production environment.

  My about 500 VMs infrastructure and I currently have the DB and vCenter on the same machine.

  I keep DB on a separate machine is better than having the single point of failure and I think that's what vmware recommends.

  However I'm looking for the Vmware documentation that points.

  I went through the best practices database link in the doc that you shared.

  strange, that VMware has not mentioned clearly anywhere if it's good to keep the DB and vCenter application on separate computers.

  Documentation need concrete who can back up.

  Thanks for your update :)

• Best practices for backup of a VM Web server?

  This question comes from another thread, that I created, but I figure I might as well start a thread fresh since it is his own question.

  Basically, I have an environment that I inherited when I started my new job within this environment, there is a lonely VM that runs from our Web server and was created using VMware player (will go to the workstation for the snapshot feature).

  I am extremely concerned by the fact that there is no backup strategy for it, so I'm interested in finding the best way to save this virtual machine.

  Being that it's a machine virtual I instantly thought, but of course I'm open to dictate what best practices.

  A lot of what I've read so far indicates to stop or suspend the virtual machine, then copy files, however is there a way to do that without temporarily take down my Web server?  It's just that we have customers in the world that has access to the server to different time zones and I want her to be in place 24/7.

  You'll have to stop the Virtual Machine and close VMware Player and uninstall VMware Player to install VMware Workstation and it is the time where you should make a backup copy of the master of the Virtual Machine.  Once installed VMware Workstation and the Virtual Machine is back and then runs to reduce the minimum time for subsequent backups you necessarily do not do such proposed by Richardson Porto although I don't disagree with what he says.

  In theory anyway, and in practice, when you want to backup you would take a cliché Hot and then copy the Parent disk such that it is now read-only and the Virtual Machine is still running while you make a copy of the Parent disk.  Once you have copied the Parent disk, you can then remove the snapshot thus merging Delta and drive Parent and now ready for the next time you want to back up the drive.  The duration of that Virtual Machine is interrupted during the snapshot warm and hot snapshot delete should be considerably less and then stop and restart the virtual machine.  The reason why I said "in theory" because while it is supposed to work in practice, nevertheless if you correctly shutdown the guest operating system before capture instant, so you do not rely on VMware Workstation to make sure that everything works all in being hot.  Not that you should have problems, it's hot, however you remove a layer of the process that has the potential of being wrong compared to when is cold, even if it is cold takes a little longer.

  In both cases, I would avoid cloning because it changes the UUID and MAC address of the clone of the parent company and by creating a second occurrence technically need a second license for the Windows operating system that is installed on the cloned virtual machine.  In other words an archived copy complete or exact unedited from the original is a legitimate backup a clone of IMO is a second occurrence but it has a different UUID and MAC address.  It would be like taking a copy of the operating system with a single license and install on two different physical computers.  Also by doing as I have suggested and make a backup copy of Master of the Virtual Machine and then just save the Parent read-only disks disk hard virtual are themselves not a computer virtual and just that copy a backup, however can be used to restore the same Virtual Machine driven and not having not any changes in the UUID MAC addresses etc.

  Finally, you should look into what you are running in the guest operating system and how to properly save Web Site and database, or user data etc in the guest operating system.  In other words, you should always have a copy backup of the virtual machine and everything that is necessary in the guest operating system to be able to restore it without necessarily restore all of the Virtual Machine.  IMO it's better to have several and backup types to have more options in a recovery scenario!

• Best practices for backup of vCenter device and ESXi hosts?

  Hello

  I have a new VMware environment based on 5.5 ESXi and vCenter Server Appliance. A few questions:

  • What is the best practice to perform the backup of the vCenter Server Appliance? I set up the camera with the embedded SQL Express database.
  • It's recommended to backup the ESXi host or is it easier to any re - install failure?

  Best regards
  ,

  Thor-Egil

  Hello

  You can use VMware VDP to backup your device of vCenter. It is included in essentials, standard, enterprise, and enterprise as well as licenses.

  I won't have backups of ESXi servers. Restore the backup would take more time that the deployment of a new ESXi.Only thing, you may want to consider is to enable logging remotely, so you can see why the hosts failed.

• Best practices for backup service console configuration

  Hello

  When you install our ESX servers, I did what I thought was best practices and created a "backup" vswitch with a second service console. Two service consoles have IP addresses on the same subnet.

  They work very well for several weeks. But today, I had a problem connecting to the consoles of the virtual machines on one of our ESX host. After much troubleshooting, I found doc below...

  http://KB.VMware.com/selfservice/viewContent.do?language=en_US & externalId = 749640

  In point 8, it is said to make sure that you do not have 2 consoles of service on the same network. (Either by the way once I removed the backup vswitch I could access the consoles.)

  I so wanted to check this - should I not create these backup service consoles?

  TIA,

  H

  You don't have to second service console, just a second link to SC.

  Add a NIC to portgroup SC (it can be standby NIC), which would be enough.

• Best practices for backup of virtual machine.

  Hello guys,.

  I have a question about the virtual machine snapshot backup option.

  In our environment, we use symantec netbackup and it is managed by an administrator of aid. It has implemented the process in a way where the snapshot of the virtual machine is scheduled and then the snapshot is saved in netbackup daily. Once the snapshot backup process is completed, the snapshot is deleted.

  My concerns:

  1 - remove the snapshot - wouldn't it increase the size of the virtual machine every day?

  2 - is enough to restore the virtual machine snapshot disaster?

  3. what happens if a virtual machine has a lot of snapshots?

  Please help.

  A snapshot (delta) file contains only data blocks that have been changed and a reference to their original location in the virtual disk Basic. Maybe http://kb.vmware.com/kb/1015180 helps to clarify this.

• ApplicationStorageDirectory - best practices for the issue of games

  So, I worked on a game that uses air. My problem is that I've been storing my game resources in the application directory. That would be fine except that the game has a built-in editor that requires the ability to write files. Adobe has locked since ApplicationDirectory for write access, so now I don't know where I'm supposed to store all my game files editable user - which is potentially active ALL game.

  The seemingly obvious choice is to use ApplicationStorageDirectory. While this is not ideal, because it seems that I would need to duplicate all the assets from the inside of the application in the repository at the start, it would provide a standard and easy to find a place to store modifiable game resources.

  However, this article (on this site) clearly tells me that I shouldn't do that. It is a good point. Backup of all game assets is messy proposal. And while I can see users who take advantage of capabilities editting as enjoying the backup, for the average player, that would be a pretty big trouble.

  What am I, so I expected to do in this scenario? I need an accessible place in writing, where the user and the application can easily access all game resources (XML, Image, MP3). I don't want to choose an arbitrary location, and I'm disabled by the application needing home redundantly data just to be copied into the destination directory since there is no way for me to delete it once it is copied since I can't write in the application.

  Thanks for the thoughts.

  Hello

  A couple of things come to mind. Is actually not Adobe that locks the application under Windows directory, it's one thing to MS permissions with folders under Program Files.  But whatever it is, it's always a problem.

  As you said, you can copy files to first launch but depending on the size, this could be annoying after a user just sitting through the installation.  It is also not very friendly when you want to uninstall.  You might want to consider sub launches the installation program with the AIR of a separate setup program that also takes care of installation of game resources to another accessible location in writing.  Maybe it's customizable by the user, but at least she is monitored by the installer that should allow you to uninstall properly.

  Is it not possible to conserve resources with your application, but the editor of the architect such as only content created by the user would be in a writable directory of the user (for example a subdirectory out of their documents folder?)

• Best practices for hardware issues

  Hi all.

  I suspect my questions are unanswered, but here go us...

  Assuming that is the CPU of the same frequency and generation, which is better: less physical Sockets with more physical cores/socket OR more physical sockets with less physical cores/socket?  (For example, a "populated with dual-core CPU Server Socket 8" or '2 socket populated with processors octo hearts'?-of course,. )

  In the same vein, which would be better: a cluster with 10 guests with simple plugs or 5 guests with double?  (Same CPU and with the understanding that there is no VM requires more resources that the host can provide.)  No claim of CPU or RAM)

  Thoughts?

  Thank you.

  Hello

  In my view, licenses vSphere is always per-socket, an important point for those who write checks!  And then there's NUMA.  If you have an idea of the size of the virtual machines, you are going to be running, you can purchase the equipment that matches your NUMA characteristics.

  As for your second question, you ask the old question of the ladder up against the scale.  You will find many opinions as people you ask.  The answer, "it depends," is largely true here if you need to enumerate and analyze your needs and your constraints.  A few things to ponder scale vs. scale out:

  -With hosts more, smaller, less virtual machines will be affected during a failure of the host

  -On the other side of the first, fewer and larger armies with multiple virtual machines can take more time to recover these VMs for an HA event

  -More great guests costs usually more little guests

  -Small hosts limit the size of your virtual machines compared to larger armies

  It has more advantages and disadvantages of each as well as what has already been mentioned in this thread.  Good luck!

• VMware has a guide of best practices for backup of VMware View & DR?

  How to properly protect a server with VMware View VMware vSphere running? Our RPO/RTO is ideally < 2 hrs?

  We have 100 customers and we use a roaming profile. TIA

  Hello

  Haven't seen specific guides. There are a few examples of 3rd party that might give you some ideas. VCenter Heartbeat also supports the component View Composer.

  Little old (2009), but interesting to read:

  http://www.EMC.com/collateral/software/technical-documentation/h6534-business-continuity-VMware-view-Celerra-VMware-SRM-blueprint.PDF

  Maybe the next version of view could address this? If you use roaming profiles, and then you just a way to replicate users DR and point to the DR View Pool, failover would take only a DNS change. Dealing with linked clones and persistent readers makes many tricker.

  I would consider the XP VM to throw objects, is the user customization, you need to reproduce for them in DR.

• Linux and oracle database installation best practices windows

  can anyone recommend the guide of best practices for the installation/design of windows/Linux oracle database servers.

  Microsoft, sql Server, provide a number of useful resources on the evolution of the default parameters that can die of hunger the operating system of resources, where to and where not to store the data in files/logs etc etc, but I've yet to find a similar guide for Oracle.

• Issue of best practice

  Hello

  I mounted the UN lab pour assess vSphere 5.

  I have a switch and 2 servers.

  Problem:

  vCenter is currently on a VM Server n ° 2. Resources are not sufficient and it is possible that I will reinstall.

  Question:

  More than the way of the East which simple / Secure / quick pour transfer this VM on the server # 1.

  Good evening

  Without the use of special features, you can also:

  -clone the virtual machine

  -migrate from the

  fishing - your vcenter server.

  -start the clone vcenter server.

  and:

  -Since the clone migrate the original stop the clone / delete it and restart the original.

  UO:

  -check that the ok to EST vcenter.

  -delete the original and keep the clone.

  After I know best practices, but in any case by causing, you Microsoft have almost no interruption of service and you have a backup available in 2 clicks.

  He must just ensure that the 2 vm (original and clone is not started at the same time, otherwise you will create a conflict of @ ip).

  Good luck.

• Best practices Oracle 11 G database machine

• Best practices for the parameter of ARCH_LAG_TARGET and DBWR CHECKPOINT database

  Hello
  
  Concerning best practices - I need to know - what is recommended or guidelines for these 2 settings of databases.
  
  I found for ARCH_LAG_TARGET, Oracle recommends he set to 1800 seconds (30 minutes)
  
  Maybe someone can guide me with these 2 settings...
  
  See you soon

  Dear unsolaris,

  First of all if you want to follow the full and incremental control points, make the LOG_CHECKPOINT_TO_ALERT TRUE parameter. You will see the checkpoint YVERT and deadlines.

  Full checkpoint is triggered when a log switch occurs and the position of the point of control in the controlfile is written in the data file headers. For just a really little amount of time, the database could be consistent even if it is open and in read/write mode.

  ARCH_LAG_TARGET setting is disabled and the value 0 by default. Here is the definition for this parameter;

  http://download.Oracle.com/docs/CD/B19306_01/server.102/b14237/initparams009.htm

  If you want to set this parameter to the top of the Oracle recommends that it be 1800 as you said. This may subject to change database database and it is better for you to check it out for who suffer.

  Kind regards.
