• When the VCAP-DCD and VCAP-DCA examinations for vSphere 5.0 will be available for registration?

  I'm a VCP5, I can't take the VCAP-DCD and DCA for vSphere 4.0 right? If the ideas when VMware will release the version 5.0 VCAP-DCD and DCA reviews? Thank you very much!

  Hello

  I asked the team of certification at VMworld on release dates and got a very vague answer. So far, there had been no mention of the beta exams VCAP nor is the same model released so I don't see it to become available before the end of February, which as noted Simon is a real shame that this means that all the VCP4 and VCAP4 holders must make the VCP5 in order to save to the Whats New course as a prerequisite. For the cost of the reviews, I think it's a real slap in the face to those who have spent time and money, get a number of certifications. Also there is no official decision of if you go the VCAP5 you will have your VCP4 improved to 5. So although validations who says that have been deleted.

  I booked my VCP5 because of this lack of news and ability to upgrade and I'm seriously considering not even reviews of VCAP5 because it takes a lot of time, money and effort to get to them and then VMware take forever to even keep up to date on how it's going or if there will be any sort of upgrade.

  I say VMware as a show of thanks for those who have spent so much time getting VCAP4 accreditations gives a 50% discount good for the VCAP5.

  I've built a whole page of resources that I use for my VCP5 if you are interested, here: http://thesaffageek.co.uk/vcp5/

  Also a page for the resources of VCAP5 here: http://thesaffageek.co.uk/vcap5-dca-dcd/

• VCAP-DCD after issue of DCA

  I just finished the VCAP-DCA, which has been a royal pain to study!  Took me 6 months and probably 300 to 400 total hours.  It was much longer that I wanted to spend, but I ended up finding it necessary to do so.

  I'm now toying with the idea of making the VCAP-DCD but want to know other people who took both who and the FLAK if they found that the DCD requires much study time or if it is less.  Just from reading the EHR Architecture, I guess it's a base much more has test because it is just done with diagram and drag and drop questions.  Without worrying about PowerCLI, SSH, advanced configuration settings, etc..  Looks like it would be more simple, but I just hope someone can check this for me before I consider getting serious about its pursuit.

  Hey Krenztor,

  I have a www.virtualtiers.net Simulator that will give you an idea of what will be the DCD.  Remember, it is more multiple choice review questions.  Also keep in mind the responses on the Simulator are not Gospel or a dump by any means, the tool must be used to learn about what the exam will be asked to you and how to use the design drawing area.  At the end of the Simulator is a Pack of study created by myself and the community.  It is on the lookout for the region you need to study on before attempting the DCD.

  The biggest problem with the DCD is it of design and very open ended.  The study material is not as cut and dry that the DCA is.  The DCA had a list of things that you need to out lab and know cold before the test, when it comes to design this is not so much cut and dry.

  I also suggest a look at the task force DCD google +.  There are a lot good information at this location.

  Good luck and happy student

  Hope this helps

• Terminologies of storage very important for VCAP-DCD

  I have compiled this post from different positions (Duncan Epping), passionate about Valentin Vipin vExpert, vmware KB, etc. So the stock of credit goes to them.

  I think this post will help the VCAP-DCD candidates for Design elements and objects of drag-and - drop.

  VMware has introduced a new architecture for vsphere storage called PSA (Pluggable Storage Architecture). This architecture using plug-ins. This (PSA) is simply the name of the new concept.

  Let's start with the native plugins of VMware.

  The Multipathing (NMP) Native is the default module that uses ESX (from vSphere). It contains the two ATAS (storage array of plug-in type) and PSP (plugin path selection) plug-ins.

  If your table is listed in the hardware compatibility list, VMware ESXi decided before (with the help of plugins PSP: VMW_PSP_FIXED VMW_PSP_MRU, VMW_PSP_RR) what paths multiple "algorithm" will be used. ESX will do natively: fixed, MRU, Round-Robin.

  Note: * native vmware Multipathing algorithm = > fixed, MRU, Round-Robin *.

  The NMP uses rules to decide who will serve as a storage array Type Plugin (ATAS) and Plugin access path selection (PSP) will be used. If you want to change these rules you can use 'esxcli' and you can find the rules in the "/ etc/vmware/esx.conf". For example the default PSP for the Bay EMC Symmetrix is fixed:

  / Storage/plugin/NMP/config [VMW_SATP_SYMM] / defaultpsp = 'VMW_PSP_FIXED.

  What does ATAS?

  The ATAS manages path fail-over, it's as simple as that. This of course will be reported back to the NMP, because the NMP is responsible to ensure a flow of e/s. The ATAS will monitor the health of a path and take the necessary steps according to the type of array. Nothing more, nothing less.

  What does the PSP?

  PSP determines which path will be used for a request of e/s, in other words the PSP addresses fixed, MRU and Round-Robin algorithm.

  Keep in mind that the type of the PSP that will be used has already been preconfigured, it's not the PSP who decides that if she will be fixed or MRU, it's the NMP which decides this based on predefined rules above.

  MPP

  What's next? It would be a Plugin (MPP) of multiple paths. VMware NMP is built by vmware, on the other hand MPP is developed by sellers of paintings. EMC is one of the suppliers who have already demonstrated their MP. Example: EMC MPP is known as Powerpath for ESX.

  -------------------------------------------------------------------------------------------------

  Different types of storage and Multipathing policy:

  Assets:-the storage system have two controllers and LUN (virtual disk or storage device) are accessible or host can perform i/o via the two controllers.

  Active-passive:-host may have I/O to and from a unit number logic via a controller only (through active controller-owner - of the LUN and not through the other)

  ALUA:-asymmetric Logic Unit Access is where the storage system simulates the function of assets (unit number logic is accessible via two controllers but alone will be the owner of it)

  Example: EMC VNX 5300 is not really active/active table. It just a group of asymmetric access logical unit.

  For this reason that ESX detect this EMC VNX 5300 as a storage ALUA and plug-in uses ATAS VMW_SATP_ALUA_CX.

  If a storage system is active/active, active/passive or ALUA, vmware PSP may be FIXED, SRM or RR based on array type. The general rule is:

  1. for an active-passive array, you will need to define the strategy of path (PSP) "most recently used". (The default PSP for active/passive storage devices is VMW_PSP_MRU). There is no path parameter with the MRU policy.

  2. an active-active array should have the policy path set to "fixed". (The default PSP for active storage devices is VMW_PSP_FIXED).

  Important: VMware does not recommend that you use VMW_PSP_FIXED for devices (table) that have the VMW_SATP_ALUA storage array type strategy assigned to them. This is because (according to my understanding) ALUA is not really active/active storage, so in this case, VMW_PSP_MRU should be used.

  3. for both active/active and active/passive array, we can choose "round robin (RR).

  The host uses an automatic path selection algorithm that runs through all Active paths connecting to arrays of active-passive, or through all the available paths connecting to the active tables. Automatic path selection implements through the physical paths available to your host for load balancing. Load Balancing is the process of spreading the i/o requests on the paths. The goal is to optimize the performance of flow as I/O per second, megabits per second, or response time.

  VMW_PSP_RR is the default value for a number of tables and can be used with both active-active and active-passive arrays to implement balancing on different paths LUN.

  Thus, the rule is to have chosen the PSP to the different array type:

  For active/active - FIXED, RR table

  For RR table - MRU, active/passive

  For ALUA table (which is really a simulated table not really active/active, active/active)-MRU, RR

  When storing ALUA, vmware SRM is also optimized / non optimized paths into account.

  So in the case of a previous path optimized operation, I/O is shifted to the optimized path (which previously used before a failover to a path not optimized)

  MRU switches to a different path when one of the following codes, meaning SCSI NOT_READY, ILLEGAL_REQUEST, NO_CONNECT and SP_HUNG are received from the table. Remember that MRU is not failback.

  For active/active SAN, the policy path sets a single failover occurs when detection SCSI 'NO_CONNECT' code is received from the table. When the path back a return will happen.

  As you can see, four against a single SCSI sense code. You can imagine what happens if you change MRU Fixed when it is not supported by the table. SCSI sense codes will be sent to the table, but ESX is not expected (NOT_READY, ILLEGAL_REQUEST, SP_HUNG) and a path will tilt.

  Great write!

  With regard to the PSP where it can be MRU or RR it is VERY important on review DCD that pay you close attention to the what the requirements are and what the instructions tell you to do.

  Other then that, great work to consolidate this information

• The VCAP-DCD, or I?

  Two days ago I registered for the review of the VCAP-CR here in Seattle, and this morning I took it. I left a lot of notes on issues, because I think they were pretty hard sometimes. Overall review difficult, but if you follow the plan of action, and took the design workshop, you should be fine.

  Here's the funny part: I expect a 10 day wait to get my score - I assume that the parties 'Visio' were classified by hand. However, at the end of the test, he showed a note of passage and said ' congratulations, you passed the examination to VMware VCAP-DCD ". After posting on Twitter, several people who have had the exam in beta version, such as the Kraut (@jasonboche) of the Jason and Duncan Epping (@duncanyb) mentioned that they have not yet received results of the exam in beta and were told by VMware that they would get them by January 10.

  So now I wonder--did pass for real, or, I have to wait for confirmation? Anyone from VMware education that can sound in?

  It is true. Results DCD is after the exam... If you are successful.

  And it's true... the results of the beta are not yet provided (maybe on the second week of January)... It of silly, but was the same as for other beta exams.

• VCAP-DCD transferred, now on the DCA

  Hi guys

  So I spent my DCD Tuesday (18th), and I must admit that it was not easy, which is currently a VCAP is worth much more.

  Also, now on my DCA (I should have probably done their vice versa?), but have the following preparation in mind:

  I should probably wait until the v.6 out and do instead? Any ideas on that? Especially when the DCA6 will be available?

  Thank you

  Thanks for the link on my blog = 0)

  I have not updated in a bit so there's a DCA lab, you can request access to the practice of build a lab VCAP direct examination (pt3) environment: DCA550 environment. SOSTech

• While doing the research resource error file system

  Hello

  I get the error "system of resource files. I want to search for a string that is present on any of my 100 files I had already recorded in the SD card. But I am able to search for a string that is present only in the first 30 files and trying to look beyond this file, I get this error. So I hope that's not because of the closure of file or the limit of connections open connection. Please give me useful advice on the issue. I had searched a lot about the error and I could not able to find any good result that solved my error.

  for(int i=0;i<100;i++){
   if(flag=0){
     try {
       fcon=(FileConnection) Connector.open("file:///SDCard/file"+i+".xml", Connector.READ_WRITE);
       // code to read data from the file
     }catch(Exception e){
       e.printStackTrace();
     }finally{
      try {
        if(fcon!=null)
          fcon.close();
      } catch (Exception e) {
         e.printStackTrace();
       }
     }
     // code to search string in the array created after reading the contents of the file
     // also set the flag as 1 if any match found on searching
   }
  }
  if(flag==0){
    Dialog.alert("No such product");
  }
  else {
    // display Matching strings
  }
  

  It is for me to code

  Thanks in advance.

  Your code to clean the file connection seems OK, there are a limited number of connections of files, but you should not exceed computer based on this code.

  However you are definitely not releasing something.  It might be connections files that maybe you do not close the input stream, so closing fcon throws an Exception.  Have you checked the error log?

  To debug it I would go with caution but all your code to see if you have a leak somewhere.  For example, to see if this code works correctly, run like the one provided here, with no treatment.  If it works to completion, the problem is caused by something in your processing code.

  You can also watch the Profiler.  Search the forum for relevant entries.

• Question about the phase-out of the VCAP

  Hello

  I just recently had my VCP5 and I plan to start studying for my VCAP but I noticed the following thread: Re: VCAP exams is being gradually...

  It is, will change the goals, etc.? This would affect me if I got my VCAP-DCA in the meantime? If I have to spend another review for the VTC VCIX or just change the title?

  Thank you

  Jake

  It is only the new track of virtualization of network which includes the new VCIX element at the moment - he there is no news on the existing VTC, DT, and tracks of cloud.

  So, for now I continue as planned to the VCAP-DCA or VCAP-DCD (you don't tell you you're aiming for)

• Passed VCP - VTC - VCAP-CIA doing next is useful and appropriate?

  Hello

  I'm a VCP - VTC. Need your opinion on the next appropriate first certification.

  Can I do VCAP-CIA or better VCAP-DCD I'm VCP - VTC already and VCAP-DCA.

  Please let me know your thoughts.

  Thank you!

  You can also point to the VCAP-CIA (or - CID) and you will have the VCP-Cloud certs as an option of the cross.

• The upgrade of the VCAP certs

  I was wondering if someone can tell me a document or information about maintenance and updates of the certifications.

  Do the last VCAP-DCD automatically to level your other certifications as I've heard?

  I'm trying to find the most efficient way to keep my certifications. Any help would be appreciated.

  See you soon,.

  Paul

  Yes, according to the official website:

  (VCDX5-VTC) VMware certified Design Expert

  Otherwise, you can get VCAP4-DCA, defend you application (could be or a vSphere 4 or a 5 design vSphere), and you get VCDX4

  Then, when you pass the VCAP5-DCD, you will also get the cert VCDX5.

• Past: VCAP-DCA

  Finally, I received a confirmation e-mail that I spent my VCAP-DCA!

  This is a great start to the week after the Monday morning

  Of course, I'm very happy with it, I had to wait for a while for confirmation, did the review on July 21.

  Next VCAP-DCD, it is scheduled for September.

  For all those who are planning to take the exam, do it! Do it! It is one of the best reviews I've ever done!

• Availability of VCAP exams?

  Seems that there is no news on the start-up of two new exams.

  During the announcement there were those info: "test for opens VCAP - DCA July 12, 2010" and "VCAP-DCD in August.

  The beta of the VCAP-DCA period disappeared, so I think that is close to being released.

  But the VCAP-CR No info... August is pretty close, but seems that the beta period has not yet does not start.

  André

  I'm at VMWorld 2010.  Talked to the admins test.  Very friendly people.  They expect VCAP-DCA to go live around September 15...

  In the meantime, I'll take the VCAP-DCA beta later this morning.  Wish me luck!

• VCAP5-DCA permission request, takes forever

  Hello

  Wanted to take the VCAP-DCA and VCAP-DCD, but in order to be eligible for the examination, VMWare should allow the candidates to the oder to the exam.

  Since two weeks, I applied for the VCAP-DCA investigation, but I don't always have any feedback.

  What is the usual waiting time?

  Thank you

• Try to export using IOM API via tcExportOperationsIntf

  Hi all

  I wrote a custom code for exports of components to IOM API Help and I am able to take exports from

  Research, resources, process form and process definitions.

  But I'm not able to export role, resource, Access Policy, policy on the approval and debugging has been established that

  ExportOperationsIntf.findObjects (Type, Name); Returns null for role, resource, Access Policy, policy on the approval.

  If I try to research role, resource, Access Policy, political approval using OOTB Deployment Manager export then I can see my components required, but the API, I am not able to do.

  I tried to give the name as * DemoRole * and "TestDemoRole" [name], but it didn't work.

  Fact ExportOperationsIntf.findObjects (Type, Name); data only works for resouce?

  All the world is facing this problem?

  IOM Env = 11.1.2.2.0

  The categories should match while yours are slightly poorly named.

  You can get a list of available categories using the following code snippet:

  	tcExportOperationsIntf = dm.getService (tcExportOperationsIntf.class) operations;
  	Categories collection = operations.retrieveCategories ();
  	for (String category: categories)
  	System.out.println (Category);
