• Looking for a best practices guide: complete replacement cluster

  Hello

  I was in charge as the complete replacement of our current environment hardware ESXi 5.0 U2 with a new cluster of servers running 5.1.

  Here are the basics:

  Currently, HP Blade Server chassis with 6 hypervisors running ESXi 5.0 U2, the company license, about 100 or so virtual running different operating systems - mainly MS 2003 R2 to 2008 R2, stores the data on without connected through ethernet connections 1 GB.

  Intended to run 7 independent servers as a cluster with ESXi 5.1, license of the company, connections to SAN be improved to 10 GB ethernet or fiber.  The range of virtual machines in the importance of 'can be restarted after hours' to ' should not be restarted or that will cost us money service interruptions.  (Looking for the options live - migrate if possible although I have my doubts, it will be an option given the cluster plans)

  I'm looking for a Guide to best practices (or a combination of the guides) which will help me to determine how best to plan the migration of VM - especially in light of the fact that the new cluster will be not part of the existing.  Given also the fact we upgrade is unable (due to problems on the chassis firmware) 5.1 before this work...

  Any pointers in the right direction would be great - look no no not a handout, just people signs

  See you soon.

  Welcome to the community - from vCenter 5.1 can manage an ESXi 5.0 host just one at a time do guests 5.0 5.1 and vmotion the VMs to new hosts - environment as the two environment will see the same SAN it will be necessary for storage vmotion.

• Best practices for a domain controller in a DRS cluster

  Hi all

  We have our virtualized 2 domain controllers.  We're in a DRS cluster, the other is on a 3rd stand alone ESX host.

  On the cluster, which is the best way to ensure that the domain controller starts first?  We lost our AC for awhile last night (again), and when turned on the cluster hosts, apparently the domain controller did not come entirely everything first, leading to a lot of problems with the other virtual machines.

  On the host of the 3rd, the second domain controller is configured to start first, with all the other virtual machines on a delay of 45 seconds.

  If you use HA, you can set the priority of restarting to 'high '. To find it by changing the settings of your cluster and "the VM options.

• Roles, permissions - DataCenter, file, Cluster, host Layout - best Practices\How-to

  Have a little problem with permissions and roles. I'm sure it will be an easy one for those of you with more experience of working with roles. I hope that my layout organization made with quote boxes is readable.

  The Organization has just spun a new host ESXi 4 for developers and added in vCenter. Developers want to use the vSphere Client\VIC to manage the ESX Server. They need rights to create virtual machines, remove VMs, clone VMs, VMs potential power. However, we don't want them to be able to reach production.

  According to the diagram below, the new host of development, labeled as "HostC (autonomous DEVELOPMENT host)", is located under "Data Center-City-2", who also owns the production ESX clusters. " And obviously I don't want developers having rights on production groups.

  Lets say I have create a role called 'HostC Dev Sandbox Rights', add users and assign directly to "HostC" below. This role contains the VM 'create' right, however when I run the wizard Creation of VM of HostC as a member of the role the vSphere Client tells me this task requires rights create VM on the level of data center! But given these developers to create VMS access on the data center would give them rights to create virtual machines in the poles of Production! Which is obviously a problem.

  I can't believe that our need to give these rights to ONLY one host in a DataCenter is rare. I don't know that there is a misunderstanding on my part of how to configure VMware roles for best practices.

  Anyone with more expirence on VMware roles ready to help me on this one? Thanks in advance!

  You can apply permissions directly to the data store.  I didn't need to go further than the clusters in our environment, but what really works for you is to place data warehouses in folders for storage.  Have the records be the names of your groups hosts and clusters.  Then place the warehouses of data for each cluster in the corresponding folder.  Then, just apply permissions for the data on the record instead of warehouses in each individual data store.  Off topic a little, but a records of something in the store of data discovered lack is the function of "views of storage" and I put a future application.

  Yes, if you set permissision to the view of the data store the user can turn opinion and see.  Extensive your permissions framework tests is guaranteed before pushing users.  Looks like you are already doing.

• Best practices in the selection of the type of authentication

  Hello
  I use Jdeveloper 11.1.2.1. I had reviewed the security and best practices (sorry Chris!) on the selection of authentication types.
  
  Frankly, I prefer basic HTTP authentication because it creates a popup of connection for you (simple - less coding), but I met some documents which make me wonder if this is to be avoided.
  
  
  1. This tutorial uses an approach based on the forms: http://docs.oracle.com/cd/E18941_01/tutorials/jdtut_11r2_29/jdtut_11r2_29.html
  
  2. this video of Frank Nymphius (in 42 minutes) uses Basic authentication: http://download.oracle.com/otn_hosted_doc/jdeveloper/11gdemos/AdfSecurity/AdfSecurity.html
  
  3. fusion Developer Guide for Oracle Application Development Framework 11 g Release 2 (11.1.2.1.0) says:
  
  The most commonly used types of authentication are authentication HTTP Basic and form authentication
  It also indicates that the forms-based login page is a JSP or HTML file, [and] you will not be able to change with ADF Faces components.
  
  4. the States of Oracle Fusion Developer Guide (Frank Nymphius) which has a side effect of basic authentication is that a user will be authenticated for all other applications that are running on the same server - you must not use it if your application requires disconnecting...
  
  5. the manual of Jdeveloper Oracle 11 g tells that basic authentication must NOT be used at all (page 776) because it is used primarily for older browsers and is NOT secure according to current standards.
  
  I was able to use Basic authentication, and Digest Http authentication very well, did not attempt to based on the forms for the moment.
  
  For fun, I tried to choose the type of authentication of Client HTTPS and received this very worthy error message (and readable - wonder for java, huh?):
  
  RFC 2068 Hypertext Transfer Protocol--HTTP / 1.1:
  10.4.2 401 unauthorized
  The request requires user authentication. It MUST contain a header field WWW-Authenticate (section 14.46) containing a fault that is applicable to the requested resource. The client MAY repeat the request with a suitable authorization (section 14.8) header field. If the application already includes identification of the authorization information, then the 401 response indicates that authorization was refused for those credentials. If the 401 response contains the same challenge as the previous answer, and that user agent has already attempted at least once authentication, then the user SHOULD be presented the entity that was given in the response, since that entity MAY include diagnostic information relevant. HTTP access authentication is explained in section 11
  
  I'm sure there is one that depends on the answer to that, but I would use the most reasonable and safe type - without too much cost if possible.

  Hello

  Basic authentication makes base64 encoding and is OK to use if the site is accessed from HTTPS. The browser actually sends authentication of users with every request, which makes this approach - if used outside of https - less than optimal. The base forms authentication is easy to implement and more record only basic authentication, it sends a name of user and password to each request. The recommendation is always use HTTPS for secure sites. Most of our samples describing the connection use https as it is a configuration that is not extended within what samples are supposed to demonstrate. For safety, "without much overhead if possible" means to weaken security. In your case, if you have tried the digest authentication so I guess that's the one with the least amount of overload

• Types of discs DC Win2008R2 best practices...

  Hello

  I am trying to upgrade my AD environmental to 2008R2 victory, and I ask for feedback on best practices for the selection of the disk type and the parameters of the virtual machine.  I intend to install new scratch and transfer AD ads and much more thereafter.

  I intend to create a volume of 50Gb for the OS itself and a 200 GB volume for departure records and other data to the user.

  In a virtual environment, it is adviceable to locate the sysvol and AD database in a separate location other than the default system drive?

  For my 50 GB disk OS (domain controller), is this normal / good practice to store it with its virtual machine?

  My drive 200 GB of user data should ideally be able to reassign to another VM intact to keep the data in case of failure.

  Which drive 'provisioning' would be normal to use with these types of discs?

  What disc 'mode' (independent / persistent) it would be normal to specify in this scenario?

  When such a virtual disk is created, is it possible to increase / decrease its size?

  Thank you very much for the comments on these issues.

  Best regards

  Tor

  Hello.

  In a virtual environment, it is adviceable to locate the sysvol and AD database in a separate location other than the default system drive?

  Yes, follow the same best practices as you would in the physical environment here.

  For my 50 GB disk OS (domain controller), is this normal / good practice to store it with its virtual machine?

  Probably yes.  Why would you consider storing elsewhere?  You do something with SAN replication or y at - there a reason?

  Which drive 'provisioning' would be normal to use with these types of discs?

  I tend to use thin for the volumes to the OS.  For the absolute best performance, you can go with thick-eager discs set to zero.  If you're talking about data sharing standard file for users, then all disc types would probably be fine.  Check it out "[study of the performance of VMware vStorage Thin Provisioning | ]. "[http://www.VMware.com/PDF/vsp_4_thinprov_perf.pdf]" for more information.

  What disc 'mode' (independent / persistent) it would be normal to specify in this scenario?

  This can depend on how you back up the server, but I guess you wouldn't use not independent.  If you do, make sure you use persistent, you do not want to lose user data.

  When such a virtual disk is created, is it possible to increase / decrease its size?

  The increase is very easy with vSphere and 2008.  Very easy, and it can be done without interruption.  Shrinkage is a more convoluted process and will most likely require a manual intervention and downtime on your part.

  Good luck!

• Registration type of best practices for updating the mapping of cascading for account drop-down list

  1. most bearing the name of choice in parent list values and related lookup has been changed in the main list of the external application, so the same should be updated in CRMOD.
  
  2 to update the value of the list of choices, do we need to DISABLE the existing value and CREATE a new list of selection.
  
  3. are there best practices to avoid the manual pick list Cascading draw for the record type account? because we have about 500 values in list dropdown to map with parent and related list of choice.

  Mahesh, I recommend disabling the existing values and create new ones. This means that the remap manually cascading dropdown lists.

• Cisco unity conn cluster integration with cucm cluster best practices

  Hi all

  I'm trying to integrate a cucm with a cluster of cuc 9.1 9.1 cluster. Some confusing points that I hope can be clarified.

  for cucm

  1. I created a voicemail with 48 ports server that will satisfy both servers of cuc

  for cuc

  I created a phone with two groups of ports system.

  two point of Group on the same server port voicemail prefix but different servers cuc. each pg also has a different sequence of the tftp servers.

  the problem with this design is that voice on the cucm ports not recorded with the port group that is configured to point to the cucsub. port groups cucpub point fits very well.

  Is how to configure the integration of a cluster of cuc. I saw the guides but it is more oriented towards stand-alone configurations.

  Help please!

  The SRND for CXN stipulates that all calls should be directed to the Subscriber with the Publisher handling overflow beyond the capabilities of the Subscriber and/or failover when the Subscriber is offline. They should not be balanced alternating.

  You can create two servers of voicemail with the wizard and give them separate device classes if you need to register for the various nodes of CCM.

  PS - You can also avoid this mess of all of the port on CUCM by integrating on SIP instead of SCCPS. In this case, you still have the CXN ports but they are only logical entities; CUCM has just a SIP trunk to each node. There is a separate for this integration guide.

  Please remember useful frequency responses and identify useful or correct answers.

• What are the best practices for creating only time data types, and not the Date

  Hi gurus,

  We use 12 c DB and we have a requirement to create the column with datatype of time only, if someone please describe what are the best practices for the creation of this.

  I would strongly appreciate ideas and suggestions.

  Kind regards
  Ranjan

  Hello

  How do you intend to use the time?

  If you are going to combine with DATEs or timestamps from a other source, then an INTERVAL DAY TO SECOND or NUMBER may be better.

  Will you need to perform arithmetic operations on time, for example, increase the time to 20%, or take an average?   If so, the NUMBER would be preferable.

  You are just going to display it?  In this case, DAY INTERVAL in SECONDS, DATE or VARCHAR2 would work.

  As Blushadow said, it depends.

• Best practices for replacement of an array of RAID10

  I have a Raid10 data table in a T710 which must be replaced/rebuilt with larger disks. I have a total of six records in the table.  The controller is an integrated PERC 6i controller.  After that, I have a verified backup, which is the best method to remove the existing table and replace it with a new one?  Is it okay to do so using OMSA because it isn't the table to start, or is it better to use the PERC BIOS utility?  Thank you.

  argolfer

  Should I turn off the server before you remove the old drives and insert new readers?  If, therefore, before I turn off the server, I have run the command in offline mode on the six discs I take?  Thank you.

  You could do that anyway, but for simplicity I would turn off the power. If you delete records while they are turned on, then the controller will see the deletion and start scoring drives as failed. If you need reinsert the readers you have to deal with foreign and rebuilt if configurations you remove while the server is online.

  If you delete them while the server is offline, then you find it easier to put readers online if you need to put them back in to retrieve data. There is no need of offline readers if remove them you when the server is out of service. If you decide to remove it while the server is on while I offline them until that table shows a failed State.

  Thank you

• Upgrade the disks in RAID 6 array: what is the best

  I have a Dell PowerEdge 2900 running Windows Server 2008 R2 and 6 x 75 GB 10K SAS drives.  PERC 6 / i controller RAID 6 with 5 drives + HS 1 (total 6 discs)

  I have 6 x 300 GB 10K SAS drives ready to trade.

  I read everything I can on hot swapping etc and what I can't find is any method to close the front discs actually pulling them.  Supposed to be via Computer Manager-> storage but not here?

  Restarted, Ctrl + R, in the controller BIOS, nothing there either.

  I have therefore 2 options:

  (1) go for it, just pull up a disc and put in a new and let them rebuild.  Repeat x 5

  (2) stop, change the music, etc.  I don't like to stop a perfectly functional server...

  Looks like #1 would be better, but without the stop disk option I'm not sure...

  Then there is the whole operation in general.  It is best to:

  (1) hot-swap & rebuild

  (2) make a backup to disk image, on all readers of a sudden and restore?

  Looks like #2 would be better... but I don't still need to re - install the software on the array of naked?

  Hello

  budcarlson

  I read everything I can on hot swapping etc and what I can't find is any method to close the front discs actually pulling them.  Supposed to be via Computer Manager-> storage but not here?

  The operating system has no control on the disks. The drives are controlled by the PERC. You must use either a software that allows the management of PERC as OpenManage Server Administrator or boot directly on THE controller's BIOS.

  You should have an option available for the physical disks offline before removing a table. Which will allow you to remove a disc without causing data corruption.

  (1) hot-swap & rebuild

  Looks like #2 would be better... but I don't still need to re - install the software on the array of naked?

  The best practices and the method supported is to back up the data, create a new RAID array with new drives, reinstall, and then restore the backup.

  Hot swapping and reconstruction are the best way to do this, but the simplest is not the best way. If you choose to rebuild and hot-swappable, you will also need either to create a new RAID array (sliced table) to use the new space or change the markup for the table.

• By the way a cluster with table of a dll

  Hello

  I will try to call the GetVersionEX kernel32.dll function. (try to determien OS version)

  One of the parameters is OSVERSIONINFOEX with the following definition:

  typedef struct _OSVERSIONINFOEX {}
  DWORD dwOSVersionInfoSize;
  DWORD dwMajorVersion;
  DWORD dwMinorVersion;
  DWORD dwBuildNumber;
  DWORD dwPlatformId;
  TCHAR szCSDVersion [128];
  WORD wServicePackMajor;
  WORD wServicePackMinor;
  WORD wSuiteMask;
  BYTE WProductType;
  WReserved BYTES;
  } OSVERSIONINFOEX, * POSVERSIONINFOEX, * LPOSVERSIONINFOEX;

  I use the library function node call in Labview with a parameter that is defined as Type-> Adapt to the Type and Format of data-> value handles. (Please correct me if this is incorrect).

  I'm trying to define the OSVERSIONINFOEX structure like a bunch, but I fixed a problem on how to set the table szCSDVersion [128] so that it is not a pointer. I tried it as an initialied byte table 128 elements and string with 128 dummy characters, but the two end up being pointers.

  Attached is my cluster (which does not).

  Any help would be greatly appreciated in the definition of this group and finally call the dll function to get OS version information.

  Thank you

  James

  You need to create a cluster of 128 bytes and incorporate that into your cluster as szCSDVersion; a cluster of all of the same type is identical to an array of fixed size of this type.  The best way to proceed is to wire an empty cluster of U8 in table for the cluster, set the size of cluster to 128 and create a constant or a control.  Drop this cluster in the right place within the cluster that you pass to the DLL.  When you get the results back, you can use the cluster to table and u8 to string table to retrieve the data as a string.

• Table of the table cluster

  Examples of creating a table of a series of clusters?  There is an example for switching from a cluster table table.

  Mark,

  The table control does not take different data types. Your best bet is to just convert to a string.

  I hope this helps.
