• change the vswitch, best practical question

  Hello

  Here is the scenario, I invited XP and I want to spend the vswitch he connected too.

  Is it safe to simply change the properties of comments in the vshpere client, set up the different vswitch, select ok. (without closing comments)

  Here is what happened last week and I would like to get feedback to see if I did something outside best practices.

  I have a xp machine who's job it is to move files within our company.  In house app, had problems with the performance, of course the bandwidth network has been a problem but also a sustained the 100% CPU usage whenever the application in the House is running. I made a few changes, first I changed the network card to a vswitch with no other guests connected, than giving a non-shared on the network connection to this comments

  I stopped our applications in the House that copies the edited files the client settings, change to the another vswitch, selecting ok...  Everything seemed fine, restarted apps and found no problem.

  The next day, I increased the RAM on the host of Meg 512 to 1024 Meg as the available physical ram was weak, and I suspected disk cache.  Stop the guest computer, editing the memory and it has increased from 1024 to vsphere...  Restarted and is the reason for my questions, which connects to run the application has been corrupted and would not load the profile.

  I should add that the application users often use the method "end task" through windows to complete the process as soon as they are sometimes does not.  Not something I tend to do what I think may be a cause of file corruption.

  My boss suggested that he believes that my approach is the cause of profile corruption, citing specifically the way in which I changed the vswitch that the guest has been connected.  My understanding at this point is that my approach was equivalent to not patch a machine and plug in another switch, and I don't see how, which could cause a windows become corrupt profile.

  Ideas of the community?  Expect honesty burtal if my method is in error.

  Change the who vswitch a virtual computer to connect during operation is perfectly accetable as only the switch that you move to can access the subnet of the virtual computer is configured for - it's like unplugging a [machine to go to an actual physical switch and plug it into a new physical switch -

• Best practice Question

  Hello
  
  I have a question for the experts in this forum. First of all, I'm a guy from network so I apologize in advance for what I am about to ask...
  
  What is the best appropriate practice when the following three tasks need to happen on an Oracle database. If these use the same port for all three actions, or use different ports, or is it still important?
  
  1 administration
  
  2. access to application servers
  
  3 replication of database
  
  Just looking for a little education on this subject and I look forward to the answer from the experts. :)
  
  Thank you

  Ok. So a quick overview of the functioning of connections to Oracle...

  First, everything that connects to the database from outside machine will contact the listener Oracle (a separate process outside the database, but the database server). The listener then hand off the connection to the appropriate database. The listener is normally configured to run on a single port (1521), although you can configure the listener to operate on any desired port or to listen on multiple ports. One can argue that the listener running on a default undefined port improves security because an attacker would have to probe potentially many ports before they found the listener. But it's quite low security account bound to the number of places at the port must be kept.

  On most Unix systems (I mean at all, but I don't know that for sure), all communication with the database is going to happen on the listening port. On most Windows systems, however, the listener will redirect the connection on another port in the range unallocated. Which tends to be a royal pain if you try to connect through a firewall. You can force Windows Server through a single port as Unix (although no doubt there are performance implications to do). You can also use the connections through a firewall proxy Oracle connection manager.

  "Administration", although potentially covers a number of different things. If you speak of "DBA connects to the database via SQL * more to do s/n-ish things", then these connections pass by the listener, there is no change. Buy you can talk about things like using the web-based Enterprise Manager (using HTTP and HTTPS on the database server if you are using the control of the database with the HTTP connection that passes on a undefined port by default (7777 is common, I think)) or by using the Grid control or using SNMP to monitor the database and related processes resulting using a number of different ports potentially.

• Group by best practical question

  Consider this example:
  
  TABLE: SALES_DATA
  
  firm_id | sales_amt | d_date | d_data
  
  415. 45. 20090615 | Lincoln Financial
  415. 30. 20090531 | Lincoln AG
  416. 10. 20081005 | AM General
  416. 20. 20080115 | AM General Inc.
  
  I want the output to be grouped by firm_id with the sum of sales_amt and the d_data
  This corresponds to the last d_date (i.e. max (d_date))
  
  Application project:
  
  Select sum (sales_amt) total_sales, substr (max (d_data), firm_id, instr (max (d_data), ' ~') + 1) firm_name)
  Select firm_id, sales_amt, d_date | '~' || sales_data d_data
  )
  Firm_id group
  
  output is as expected:
  
  firm_id | total_sales | firm_name
  
  415. 75. Lincoln Financial
  416. 30. AM General
  
  I know it works, but my QUESTION is: is there a better way to do and is the method described above to concatenate the columns when you want to group several columns against best practices.
  
  Thank you very much!

  Here is a way that uses analytical (I just like them):

  SQL> select * from sales_data;
  
               FIRM_ID            SALES_AMT D_DATE               D_DATA

• Best practical Question - update the query (see object) based on the drop-down list selection

  I have a question about the most efficient way to perform the following task:

  I create a page that contains several DVT components to display data based on specific requests.  Top of page I am hoping to have a drop down menu (selectOneChoice) that contains dates different and based on what the user selects (i.e. 2010, 2011, 2012, 2013, etc.), this will update the query in the view object of some (i.s. WHERE Date = '2011', or WHERE Date = 2013"), and then you view the appropriate data in the DVT.  What is the best way to do this - from a point of view bean managed / page, as well as the View object?  Advice/documentation would be appreciated.

  Thank you!

  When you drag the vo executeWithParams one another that will create links for operations such as 'executeWithParams2', 'executeWithParams3 '. On the method that you use to update a view by calling the executeWithParams operation, you call the other operations too.

• A practical question on the recycling of the session

  Consider the following in ADF Faces web application scenario.

  A user works with a procedure that uses global temporary tables (with validation preserve lines option) and then remains inactive for a period of time. Is it possible, that a user B is then attributed to the same Oracle session and that is going to work with the same procedure above, she can find to the left of the execution of the user data?

  Thank you

  Unfortunately, it is a practical possibility and can occur in two cases:

  1. If the default setting of jbo.doconnectionpooling = true is used,

  whenever a user session end then using a plug-in application (usually at the end of each HTTP request),

  module of the application instance is dissociated with the JDBC connection that he used on this request and he returned to the JDBC connection pool.

  2. If the default jbo.doconnectionpooling = false setting is used,

  but the default output level Managed for the modules of the application is used, and passivation occurs.

  In the case that your solution is to use the release reserved by default.

• ReReplace best practices Question

  On my page, I have a form with a text box. I want to replace the ampersands and quotes with the correct code. My question is, is it better to run rereplace it that I take the formdata and store it in my database or should I treat as in the query when CF assembles the page?

  Thanks for any help/tips

  This is how it is to be used now.

  I think you will find that as organizations acquire more data that find other ways to use the data in the future.

  The general rule is to store data as neutrally as possible and format it for the desired display when it is displayed, in this case in html.  Thus, when this time arrives in the future that they want some otherwise disply you do not take the problem of the deconstruction of the HTML stored in the database and convert it to a format.

• Single user, working on both machines, best practical question

  I use Dreamweaver at home and at work.  I'm working on my sites only.  I have just started working with DW and don't know the best practice to achieve.  The way I do now is through a folder synchronized on both machines that hosts the site.  The establishment is a local folder on the two machines that automatically syncs on the WWW.  I created a site on my machine at home with a folder root for the site and the images and then created another site on my work machine and was pointing at the root sync folders.  Is the best practice for this set to the top.

  I guese that im afraid of is the feature of auto update of links and such to within DW.

  Thank you!

  I have the same configuration and DW Check In / Check Out feature works for me.

  This requires a local copy of the site on home and work machines more copy remotely on the web.

  I have check no matter what files I need to work, modify and then download and archive when I'm done.

  DW manages everything.

• I want to confirm a best practices question - Acrobat XI forms Standard used on an Apple operating system - is this a problem?

  I'm creating forms in Acrobat XI Standard on a 64-bit Windows 7 computer. I have reports that the forms do not work and I see silkscreen where policies in the fields of the form are larger and moved than in the original form, that I created. What happens on a Apple product. So is this a problem? I read a post of 2007 saying it was. But it is still today, and if so, is it possible to deliver a formula that works with both Windows and Apple using Acrobat XI?

  Thank you

  In addition, an extract does not support the features of shape, such as JavaScript, so a form most likely does not as expected. What you describe is one of the ways.

• Question about default

  So, here's a practical question, I got horribly wrong:

  

  Now, I answered A under the assumption that the default NUMBER is not nullable (the answer is (B). However, it makes sense for the data types different have a similar defect. My question is are the NULLABLE defaults for my columns in this case?

  Thank you.

  Columns in Oracle have NO values by default unless you give them one and are nullablel, unless you say otherwise.

  None of the columns are NOT NULL and there is only ONE line where PAY_RATE is greater than 20.

  While a SINGLE line will be updated. The only other line has NULL for PAY_RATE and a comparison with the NULL value will not match the predicate.

• Best practices ISCSI VMK? How much per physical nic?

  Hi guys,.

  I have a practical question best.

  I have an ISCSI unit with two controllers. Each controller has two ports. The configuration is the following:

  A: controller

  P1: 192.168.7.1/24

  P2: 192.168.8.1/24

  Controller b:

  P1: 192.168.7.2/24

  P2: 192.168.8.2/24

  Each controller is connected to two switches. P1-> P2-> SW2, SW1.

  Each server has two network adapters, dedicated to ISCSI traffic. The question is: VMKs how do I run a physical NIC? One? Or two?

  I've set up so be it, but I'm not sure how it should be done. Currently, all guests have a VMK by NIC my argument is despite VMKs how I, the flow is still limited to 1 GB/s per port of the server (unity of ISCSI is 10 Gbps per port).

  Option 1:

  Server A:

  • MI 3
    • VMK1: 192.168.7.20/24
    • VMK2: 192.168.8.20/24
  • NIC4:
    • VMK3: 192.168.7.21/24
    • VMK4: 192.168.8.21/24

  Option 2:

  Server A:

  • NIC3:
    • VMK1: 192.168.7.20/24
  • NIC4:
    • VMK2: 192.168.8.20/24

  Is it not wise to have a physical NETWORK card with two VMKs? I'm not sure if two VMKs physical NIC is "good" because it could lead to performance?

  TIA!

  A VMK by NIC is the supported configuration. If you do differently, you may not be able to properly configure the iSCSI.

• Captivate 8 button Retake Quiz - return to the slide of the wrong question

  Hello

  I have not yet fixed my problem of button retake quiz. I have a project with several questions of practices not classified (hot spot, drag n drop, 2 several multiple choice answers) followed by 9 questions 'real' test. I want students to return 'true' test questions when they click on the recovery test button. Now, the recovery quiz button brings back me to the first multiple choice question in the practical section - not the first 'real' test question.

  In the Interactions for the first multiple choice question (and the 2nd as well), I see that nothing appears in the neck to include in the questionnaire and responses report = no, but an entry appears in Objective ID and ID of Interaction. I don't see this credential anywhere in the QUIZ tab - I wonder if this is what pushed the button quiz in this slide.

  

  Attempt to correct:

  I saw the response of Lilybiri to "Captivate 8 resume Quiz" entry. It seemed like the perfect solution to my problem. So I created an Action conditional Advanced:

  If cpQuizInfoAttempts is greater than 1 go to (1 'real' test slide #) continue on the other

  The 'real' 1 slide test I put this conditional action on enter.

  It did not work. Please help me determine what I am doing wrong and how to fix this quiz of recovery. THANK YOU VERY MUCH! I'm getting desperate!

  Smiles

  Susann

  You must have read my response wrong. Condition is OK, but you have to trigger on enter for the first issue of practice, not on the first slide of the real issue. As the recovery button will take the user to the first practical question slide, this action will be evaluated and the jump to the first slide of the real question occur. Assumed, here are that all the slides in practice before all the question slides.

• Question about Resource Pools

  Hi guys,.

  I studied pools of resources in my lab at home in preparation for the review of VCP 4.  I read the pdf pools resources management:

  http://www.VMware.com/PDF/vSphere4/R40/vsp_40_resource_mgmt.PDF

  I'm a bit confused, I hope someone can clear this up for me.  A practical question indicates that a virtual machine will always fail to turn on if reservation of the virtual machine cannot be guaranteed, however in the KB article below he states that admission control can be disabled.

  http://KB.VMware.com/selfservice/microsites/search.do?language=en_US & cmd = displayKC & externalId = 1007006

  It is, so I think I understand the fact of not being able to guarantee a reservation of the machine does not necessarily prevent machine market because admission control can be disabled.  Is this correct?

  Reservations must be guaranteed as directed by your comment. Which relates to resource pools.

  Admission control is specifically related to HA and ensure that a virtual machine cannot be turned on if it's availability can be ensured according to admission control policy. HA can use reservations VM more memory General fresh in these calculations.

  Disable the admission control would allow you to power on a virtual machine even if the availability of this virtual machine could not be provided by HA, that is a different situation when the virtual machine lives in a pool of resources.

  Just because you use HA does not necessarily mean that you use resource pools or DRS
