• Removal of host SDR data warehouses

  Hello

  I have a scenario where I want to migrate to a host and the VM between two clusters. I unfortunately had a number of DTS data warehouses attached to the host, no virtual machine is running from these storages of data on this host... I'm trying to disassemble stores but as expected get the error indicating that data warehouses are part of a cluster of EIM.

  Is it possible to no disturbance delete Host data warehouses.

  Thank you

  Steve

  So, what you want, remove some cluster DTS data warehouses and pass a host of a DRS cluster to another's is?

  Try the following steps:

  (1) remove the DTS cluster data warehouses, just move the data store outside the cluster for DTS;

  (2) move the host to the new DRS cluster target, if you have virtual machines running on it and cannot put the host in maintenance mode, you will need disconnect host, remove from the inventory and then add the host again to the new cluster.

  (3) If you wish, add data warehouses to the DTS of the new DRS cluster cluster.

• Question about removing a HOST and add it again with the other IP management

  Thanks in advance for your help.

  I have an environment with two centers of data/clusters inside my virtual Center 2.5

  One of her consistes of clusters on two ESXi 3.5 licensed nodes. Each of them has 2 VMKernel ports form management. One of them has an IP (A.A.A.1) with any VLAN, the other port is in VLAN111 and IP (B.B.B.1). The other host ESXi has A.A.A.2 and B.B.B.2 IP.

  The other cluster has two 3.5 ESX (not i) and they have a single port/IP managemente (in the VLAN111, which is the same as the other cluster)

  The first cluster appears associated with the virtual center with the No.-VLAN port (IP A.A.A.1 and 2). Is a problem for me because I need to access the first cluster of other machines having no visibility on the A.A.A.x subnet, but it has visibility to the VLAN111. If I connect to the virtual Center, he shows me the IP A.A.A.x but when I try to access them, I can't.

  I would like to do the following WITHOUT affecting the first cluster:

  -Remove each host in my Center Virtual (The VM will continue to work without problem?)

  -Add each host the virtual Center, but this time I'll add the IP VLAN111 (B.B.B.x)

  My question is if these will generate instabilities problems on my dock.

  Thanks in advance

  This process has worked for us when the old VC (2.5) ESX Servers moving again VC (4.0).

  2. unplug all battery ESX servers.

  3 remove all ESX server farm servers.

  4. Add the ESX Server to new cluster in VC (4.0).

  5. configure the HA and DRS on the new farm.

  Used for over 700 ESX servers with zero impact.

  Maybe it's a good idea if read you on the encapsulation and data hiding.
  Or the fundamental principles of programming procedure (leaving aside the OO principles
  as a first step).

  Your function could well be designed to set the values default to * a user object *,.
  but where this user object is stored and how much should really be his
  company. If possible a function should do something:
  -validate a user object;
  -Put it in the session.

  It's two things.

  What happens on the track when you want valdiate a user but object
  * don't * want to session? It could be part of your process of
  creation of the user record in the first place, before putting it in the DB.
  You don't want to write another function which is almost the same.
  with the exception of the end of the session. So you have two pieces of code to maintain
  If something changes. It is, of course, just the visible part of the iceberg.

  My approach here would be to put a vanilla user object (a structure in the)
  CFC instance taking bits and user data elements), and * back * that.
  Then in your calling code you assign to the scope of the session.

  Google "getters and setters.

  In general, a function should only manipulate data in its own scope of application
  (past arguments and local variables in the function (or the CFC
  instance) and then go back a result based on this manipulation. They
  should not manipulate anything "outside". The session scope is
  intrinsically outdoors.

  Except that I would have to this would be to have a session manager, which is
  especially used to hold the values in the scope of the session. While its
  job: managaing the scope of the session. He don't care about whether it is a user
  permissions object or authorization, or a [something] State that
  persists for the session; It handles just to put things in and to
  things out of session.

  However, for good practice, there is a situation where it is not the
  best approach. However, I don't think this falls into this category.

  Dan probably roll his eyes and goes 'too complicated', but I think that
  We differ in opinion as to what is a good level of "complication" (I wish I
  you mean "abstraction"), which is too much and what is too little ;-)

  The error would be thrown by the code that performs the function call, so the

  I mean exactly what I said (that is to say: I was not at an angle). In general, the
  the code in a function should not out anything. An if function
  * Return * something, no exit it.

  I can't recommend which specific books / web pages to read, but I recommend
  you google on the place of writing functions coding practices.

• A host server not able to take the update on the wsus Server

  I have 2012 production WSUS server in our environment. We deploy the wsus Server security patches, but there is a host that does not patch Server wsus rather take the patches from the Microsoft site directly. Can someone help me with this.

• I can't remove individual cookies, they reappear just without seeing the site.

  I'm the procedure indicated on the site of Firefox. I can't select a set of cookies to delete by selecting the first cookie in a game, then by pressing SHIFT - END. I guess the END is just the last point in the list you want to select. This does not (Mac OS 10.5.8, Firefox 3.6.15). I can only remove 1 cookie at a time. Sometimes when I delete a cookie it just reappears. There are cookies that I just can not remove, even within the same session, even when not having another open window which can be on a different site from Firefox)

  TACO with Abine prevents displaying highly targeted advertisements using the detailed information about your habits of web surfing more of 100 different online advertising networks (including Google, Microsoft and Yahoo). TACO disables most behavioral advertising by setting 100 + permanent, generic and non personally identifiable "opt-out" cookies directly in the browser.
  
  
  
  Unlike other opt-out solutions, this tool will make the persistent opt-out cookies completely. In other words, clear the browser cookies will delete all other installed cookies, except them.

• What is the best practice for a 'regular' Server VMware and VDI environment?

  What is the best practice for a "regular" VMware Server and VDI environment?   A single environment (ESXi and SAN) can accommodate two if it is a whole new configuration?  Or even better to keep separate?

  Enjoying inputs.

  Quick and dirty answer is that "it depends."

  serioulsy, it depends really two things budget and IO.  If you had the money for two without then buy two and don't have to host your server environment and the other for VDI desktop, their IO profiles are completely different.

  If this is not the case, try to keep each type of use for their own dedicated LUN.

• 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!

• What is the best practice to block through several layers sizes: hardware and hypervisor VM OS?

  The example below is not a real Setup, I work with, but should get the message. Here's my example of what I'm doing as a reference layer:

  (LAYER1) Hardware: The hardware RAID controller

  • -1 TB Volume configured in the 4K block size. (RAW)?

  
  

  (Layer2) Hypervisor: Data store ESXi

  • -1 TB of Raid Controller formatted with VMFS5 @ block size of 1 MB.

  
  

  Layer (3) the VM OS: Server 2008 R2 w/SQL

  • -100 GB virtual HD using NTFS @ 4 K for the OS block size.
  • -900 GB virtual HD set up using NTFS @ 64 K block size to store the SQL database.
  • 
    

  It seems that vmfs5 is limited to only having a block size of 1 MB. It would be preferable that all or part of the size of the blocks matched on different layers and why or why not? What are the different block sizes on other layers and performance? Could you suggest better alternative or best practices for the sample configuration above?

  If a San participated instead of a hardware on the host computer RAID controller, it would be better to store the vmdk of OS on the VMFS5 data store and create an iSCSI separated THAT LUN formatted to a block size of 64 K, then fix it with the initiator iSCSI in the operating system and which size to 64 K. The corresponding block sizes through layers increase performance or is it advisable? Any help answer and/or explaining best practices is greatly appreciated.

  itsolution,

  Thanks for the helpful response points.  I wrote a blog about this which I hope will help:

  Alignment of partition and blocks of size VMware 5 | blog.jgriffiths.org

  To answer your questions here, will:

  I have 1 TB of space (around) and create two Virutal Drives.

  Virtual Drive 1-10GB - to use for OS Hyper-visiere files

  Virtual Drive 2 - 990 GB - used for the storage of data/VM VMFS store

  The element size of default allocation on the Perc6 / i is 64 KB, but can be 8,16,32,64,128,256,512 or 1024 KB.

  What size block would you use table 1, which is where the real hyper-visiere will be installed?

  -> If you have two tables I would set the size of the block on the table of the hypervisor to 8 KB

  What block size that you use in table 2, which will be used as the VM data store in ESXi?

  ->, I'd go with 1024KO on VMFS 5 size

  -Do you want 1024KO to match the VMFS size which will be finally formatted on top he block?

  -> Yes

  * Consider that this database would eventually contain several virtual hard drives for each OS, database SQL, SQL logs formatted to NTFS to the recommended block, 4K, 8K, 64K size.

  -> The problem here is THAT VMFS will go with 1 MB, no matter what you're doing so sculpture located lower in the RAID will cause no problems but does not help either.  You have 4 k sectors on the disk.  RAID 1 MB, 1 MB invited VMFS, 4 k, 8K, 64 K.   Really, 64K gains are lost a little when the back-end storage is 1 MB.

  If the RAID stripe element size is set to 1 024 Ko so that it matches the VMFS 1 MB size of block, which would be better practice or is it indifferent?

  -> So that's 1024KB, or 4 KB chucks it doesn't really matter.

  What effect this has on the OS/Virtual HD and their sizes respective block installed on top of the tape and the size of block VMFS element?

  -> The effect is minimal on the performance but that exists.   It would be a lie to say that he didn't.

  I could be completely on the overall situation of the thought, but for me it seems that this must be some kind of correlation between the three different "layers" as I call it and a best practice in service.

  Hope that helps.  I'll tell you I ran block size SQL and Exchange time virtualized without any problem and without changing the operating system.  I just stuck with the standard size of microsoft.  I'd be much more concerned by the performance of the raid on your server controller.  They continue to do these things cheaper and cheaper with cache less and less.  If performance is the primary concern then I would consider a matrix or a RAID5/6 solution, or at least look at the amount of cache on your raid controller (reading is normally essential to the database)

  Just my two cents.

  Let me know if you have any additional questions.

  Thank you

  OEM 12 c 5 release is the only monitoring in our environment... is there a better model of practice on what aspects need to be monitored and their default values?
  

  This doc for 12 c DB is very useful, it's best practices for high availability. They talk a lot about the RAC/DG monitoring.  https://docs.Oracle.com/database/121/HABPT/monitor.htm#HABPT003

  version 11.2 is here https://docs.oracle.com/cd/E11882_01/server.112/e10803/monitor.htm#g1011041, I read them both though, as there are some new features in version 12 c who may still apply to 11 g.

  Regarding the parameters/models go, if you create a template of the target type (monitoring sc_results.php-> create-select target type-> type > select category/target), this will include all the parameters of the type of target (including the CEO) and as close as you'll have to 'default thresholds' Oracle.  It is the best branch of the teams effort produced.   Of course, they will not be perfect for everyone, but it's a starting point!

• Best practices - virtual disk of Raw device mapping vs

  Hello

  A small question about the configuration. What would be described as the best practice to configure a comment server that required a large amount of disk space? What is the preferred option:

  1 - create a virtual machine with a mapping of raw device to the LUN (on a san)

  or

  2 - create a virtual machine with another large virtual disk that is in a data store on the LUN (on a san)

  Thank you

  Dave

  Kader you are limited with 2 TB in any case (except using the iSCSI software from within the guest operating system), the only arguments are:

  (1) use RDM if it is possible that you will connect to this physical machine LUN. Or you already have the unit number logic of a physical machine as a large file server.

  (2) VMFS use in all other situations - VMDK give flexibility, you can migrate the virtual machine where you want.
