• When the Active Server is shut down normally, the passive server does not start the service

  Hi friends,

  I have a question for the vCenter heartbeat,

  When the Active Server is shut down normally, the passive server does not start the service.

  Is this normal?

  Thank you.

  He starts the services on the passive server because the correct judgment still leaves the server active as being the "main".

  Stop all services of it properly. And after it comes back online replication starts as before, so that no service must be started on both servers. (in this case that you will have questions)

  Please note that on a server computer, you have 2 possibilities to "stopping down": the BONE and the option of status and control of the server Vcenter Heartbeat

• Good practices of FIFO: updated old cluster or create new

  Hello world

  My question is more on "good practices" that really solve a problem.

  I use FIFO to send images and other data from a producer to a consumer.

  I created a cluster which includes all the data that must be sent through the FIFO.

  My question is: can I create a new cluster to each loop of the producer and put this cluster in the FIFO or should I set a shift and then register and update the data of this fallen registry change by sending in the FIFO?

  Below you will find two screenshots that sums up the idea (NB: these aren't the real VI.) We come here to show the general idea).

  If there is a difference (in the way that the computer uses memory for example, or something else...) between these two methods of programming, you will give me some details so that I can understand why to use one over the other, please?

  Thank you very much.

  Best regards.

  I think that there is very little difference in terms of performance (perhaps the registry approach change is slower than sliiightly - but probably not noticeable in most cases).

  The main reason you want to use the shift register approach is that if you update only certain values before sending the data in the queue, those that would be lost if you created a new cluster each time. For example, if 'Directories' was constant, you could just power/updating that once the value to the registry to shift and just update the part "ImageAcquired" of the cluster before you send it in the queue. This also means that if you update your cluster to have more elements (using a type-def, of course), you can be less worried about having to update the individual elements.

  I think it is less a problem of performance (both are valid and effective) and more a matter of maintainability and flexibility.

• What is a good practice to manage LOV in jdev apps?

  Hi, experts,
  In jdev 11.1.2.3,.
  
  In our projects, there are numerous LOVs whose value are stored in a common dictionary table, for example in the refcode table:
  refcode (id, low_value, high_value, sense, domain_no),
  Different LOVs can extract value peers (low_value, meaning), or (high_value, sense) refcode table by using domain_no as the filter criteria.
  
  In the user interface of the user, the values of field/code number should be displayed by a sense of refcode password
  To achieve this, I'll create many links between the different tables with refcode,
  and create your entity refcode consider the secondary entity views.
  
  I feel some odd (because so many associations with the same table refcode),
  What is a good practice to manage LOV in this way?
  
  Thank you.

• What is good practice to update fields of VO on the user action

  Hi all
  
  version: Jdeveloper: 11.1.2.1.0
  
  I have an obligation to update some fields in VO (such as status, date of approval) to the "Approve" button is clicked, I want to know what the good practice of VO update in this case because I see two options for me here.
  
  1 1 manipuler handle in a managed bean, get the iterator VO and to update the VO and invoke the validation operation.
  2. write a method in AM and get the VO, update the attributes of the vo and call commit transaction db.
  
  Can anyone suggest what is good practice in this case?
  
  Kind regards
  Delighted Nuka.

  How about a combination of the two?
  The requirement is a requirement of the company, the method must be implemented in the model. Use a method in the vo or am for her. This method you expose on the customer interface and then call through the layer, just like you call create method error. After you call the method commit the bean or no later than the point in your workflow.
  You should not call commit inside the method as method then can be part of a larger transaction.

• Failed to install Vista Service Pack 2 (32-bit): do not normally reboot system...

  When update SP2 introduced a few days ago, I tried to install it next to other updates. He installed the files, asked me to restart to make the facilities to be effective, and again started installation of the service pack in 3 steps (of course he has shown not to turn off the ot system to disconnect it). When he began to install while closing, the first step has been successful at 100%, and when it was 98% done in step 2 THE SYSTEM of COMPLETTELY STOP ALL of a SUDDEN WITHOUT ANY WARNING. When I rebooted the system, it recommended to launch startup repair and asked me if I want to restore the system and when I accepted, it AUTOMATICALLY restored to a previous point and windows started normally (before you start to install SP2, it has shown to do a restore point)...

  Now, when I checked in the history of the update, all other updates of internet explorer, windows etc defender have been installed except SP2. What is more worrying is that my laptop is not STARTING NORMALLY since then. Always asking me 'Launch system repair' at the beginning - to go to system restore... and then only from the windows... even if just RESTART instead shutdown and startup, the same thing happens... So, I started to keep mode "sleep" when not in use (I was doing important work in small sessions and did not dare to stop)

  I tried to install SP2 twice since then and each time the SAME THING REPEATED.

  Now when I rebooted my system that's repeatedly went to 'Launch Startup Repair' but not to the point where he asks me if I want to RESTORE... instead, it's just SHUTTING DOWN...

  I am running Vista Home premium on my laptop HP Pavilion DV2000 series with processor 2.1 GHz intel core 2 duo, 2 GB RAM, 160 GB HD, NVIDIA graphics 512 MB, lightscribe DVD burner...

  No idea what can do now? Any suggestions would be much appreciated...

• SWFVerification without restart/reboot the server

  I was now two occurrences of SWFVerification is not activating when the values are added to the application.xml for a client application.

  We allowed him with an empty dir, and any player will always through.

  I tried to add a "is not not-really-the - player.swf" to confirm that he will reject all other connections, and they always get through.

  I tried to reload the Application, and which also had no effect.

  In a previous proceeding, only after the virtual server is restarted, SWFVerification will start to work.

  This question quite important for us - as we host 100 s other connections of client application on several boxes that make SWFverification is not just simple 'reboot' these boxes.

  Any suggestion on how to get SWFVerification to work without having to restart the virtual server or FMS itself?

  Thank you.

  -Va

  Figured it out.

  From what I saw. the Admin "unloadApp" command is not an effect the SWFVerification. However, "reloadApp" seems to indulge the SWFVerification on a modified application.

  Kind of beginner to the CARS, just started?

  I know that the order to stop it.

  Instances of database 1 stop

  2 stop the Services on the node database

  3. stop the node level apps

  4 stop the Listener

  Can someone let me know the order to restart?

  Thank you

  Hello

  Instances of database 1 stop

  2 stop the Services on the node database

  3. stop the node level apps

  4 stop the Listener

  1. If you stop instances of database - community services which if accessed by client customers that it will get the problem (they would say that they are unable to connect to your databases). The Central battery will go into an abnormal state - compared to your normal startup and shutdown procedure (reason for that since your listener are always up and try to provide services (services database).) Maybe they cannot provide the service because the database is out of service. If you need to stop your stack of middle ware initially.

  2. after the middleware stack you must work on the stop of the listeners and services (which is logically the scoop of cluster and data bases - right at the bottom) with other dependencies.

  3. then, you can stop the database followed by the applications node.

  4. Finally cluster ware

• Pragma EXCEPTION_INIT or RAISE_APPLICATION_ERROR - that is good practice

  Hello

  I have came across a point where I need suggestion and views on error handling. However I use above all error handler.
  But in case the base unit (inside) / program that calls that one would be preferable to use the PRAGMA EXCEPTION_INIT or directly use RAISE_APPLICATION_ERROR.

  Here's the example I've tried

  SQL> DECLARE
    2  L_CNT NUMBER;
    3  NO_DATA_FND EXCEPTION;
    4  PRAGMA EXCEPTION_INIT(NO_DATA_FND,100);
    5  BEGIN
    6   SELECT 1 INTO  L_CNT
    7       FROM DUAL WHERE 1=2;
    8  EXCEPTION
    9      WHEN NO_DATA_FND  THEN
   10      raise NO_DATA_FND  ;
   11  End;
   12  /
  DECLARE
  *
  ERROR at line 1:
  ORA-01403: no data found
  ORA-06512: at line 10
  ORA-01403: no data found
  

  Or is better

  SQL> DECLARE
    2  L_CNT NUMBER;
    3  BEGIN
    4   SELECT 1 INTO  L_CNT
    5       FROM DUAL WHERE 1=2;
    6  EXCEPTION
    7      WHEN NO_DATA_FOUND THEN
    8      RAISE_APPLICATION_ERROR(-20001,'OR is this good way of handling');
    9  End;
   10  /
  DECLARE
  *
  ERROR at line 1:
  ORA-20001: OR is this good way of handling
  ORA-06512: at line 8
  

  No, it's not the same.

  Let's say you had a PL/SQL code you want to process the cases where you get an error ORA-01234 (for example), and you want to write an exception handler for it. You could use exception_init for card ORA-01234 an exception called MY_EXCEPTION and then use "when MY_EXCEPTION" in your exception handler. It has NOTHING to do with the throwing of an exception. You can also use this name to throw the exception directly

  raise_application_error throws an exception with a specific number and text associated with it. The error number must be within a specified range (-20000 29999 if memory serves).

• vCenter Server with vSphere Essentials best practices for small business

  I hesitated to post this thread for fear of redundancy, but I wasn't able to find an answer in previous discussions.

  I read the installation documentation for vSphere Essentials vCenter Server installation.

  
  Is it a good idea to install vCenter on my ESXi host as a virtual machine?  I don't understand how the server can be installed as a virtual machine if she must always be on.  What happens when I do the updates of the hypervisor, ESXi (4.0 to 4.1)?  This would not cause the vCenter Server to disconnect?

  Because I have Essentials, I don't have a HA and cannot migrate the server vCenter Server to another host as shown in the installation documentation.

  Thank you

  It should not be a problem - if you manually perform the update using either the esxupdate or vcenter command vihostupdate does not at all in the game - if you use VUM he actually intitiates the vihostupdate order - when restarting the host to be reconnecting to vcenter once it is running.
