• virtual network card to the physical network mapping and default loadbalancing

  What Virtual Machine virtual network card is map physical NIC.

  For example.

  lets assume Vswitch1 on host1 esx dedicated for the network of the virtual machine (port group) and it has 6 cards network linked to it (vmnic1, vmnic2, vmnic0, vmnic3)

  Load policy (default) Balancing - from the originating virtual port (it balances only outbound traffic through all the nic assigned to vswitch1 right?)

  ESXi host1 <-Vswitch1 (the VM network) <---(vmnic 0-vmnic 3)

  Lets assume that esxi hosting 6 virtual machines and each virtual machine has two network cards configured.  Through some documents, come out of that when the virtual machine is running, it gets connected to the ports of availabe on virtual swicth. say, I turn on the virtual machine in the order VM1, VM2... VM6.

  Vmname virtual adapter port on virtual switch1 Mapping of the physical network adapter                        

  VM1 eth0, eth1 1.2 which mappeed of the physical NIC to eth0, eth1?

  VM2            eth0,eth1                              3,4                                      ?

  VM3            eth0,eth1                              5,6                                      ?

  VM4            eth0,eth1                              7,8                                      ?

  VM5            eth0,eth1                              9,10                                    ?

  VM6            eth0,eth1                              11,12                                  ?

  Since we use load balancing based on the virtual port, can two virtual map of the same virtual machine are mapped to the two physical NETWORK card I want say eth0 VM1 is mapped to the (physical nic) VMNIC0, VM1 eth1 get connected VMNIC1 (physical nic).

  It would be great if you could explain how the virtual network adapters are mapped to the physical NIC Y at - it a command or a script to the list NIC(of all vms hosted on esxi) virtual NETWORK adapter mappings physical in detail.

  Is there a way to know what virtual NIC to connect to which physical NIC

  With the virtual NETWORK adapter, you hear the virtual card inside the VM? If if and when you use several VMNIC like you, there is no visibility in vCenter (usually vSwitches, we see with Distributed vSwitches).

  However, you can use the command-line ESXTOP tool in the view 'n', for the connection between the virtual machines and the outgoing vmnic.

• The disk of light and SDS Cache activity

  I have a relatively new W530 with the installed at the factory 16GB drive HARD drive cache and the ExpressCache software (working properly according to the Lenovo-recommended test). I want to know if the drive activity light shows HD activity only or also SDS hides.

  My observation is that for a long time the drive activity light is on permanently. The first time that this has happened, the warranty support told me that the HD failed and sent me a new. (They don't seem to know anything on the internal tables of health HD I thought existed and could be interrogated with a special software). Anyway, this seemed to solve the problem for a few months, but it is recurring lately.

  Looking again at the Task Manager/Performance tab/Resource Monitor tab / Disk, I can see that the larger disk of the user's ExpressCache service (as it was the first time). I stopped this service and set it to manual, and the constant activity stopped shortly after. He has not re-emerged in the last hour or two. Although the light is off now (for the most part), I still don't really know what that means; the first question remains...

  No matter what light you can pour on the light function (no pun intended) disk activity would be appreciated! -JCW2

  
  

• Expulsion of objects based on the aging of the dimensions of time and no cache

  Hello
  II uses a cluster of coherence (extend) and wish to implement a policy of aviction for each object inserted into the cache.
  
  Documentation, I read I understand political custom eviction are ALL size based and not time based (way, expulsion is triggered when the cache is full and not hide when the aging of the affected object time).
  
  It there a way to implement these evictions?

  Hi Reem,

  When you say that you want to trigger my own code/class at this end of the cache item what exactly do you mean?

  1. don't you want to control what happened to expire?
  2. don't want to trigger a treatment when the entries are expired?

  If it is 2, then you can use a normal cache listener. In the entryDeleted of the MapListener method you can cast a delete the MapEvent isSynthetic CacheEvent and call that returns true if the event is due to expulsion or false if the event is due to a real.

• In the physical layer star schema

  Recently, I came across a question from a colleague. The discussion continues as follows:
  He asked me what is the star schema, and where you can set? Physical layer or layer MDB?
  I've explained on the star schema and responded to his rest of the doubt that we define it in the layer of MDB.
  His immediate question is why can not we define it in the physical layer? Since MDB layer allows to build three-dimensional models, therefore, we must build it into this layer itself is my answer. But later in the evening, when I started to reflect on my way to the House, I started to think about his doubts.
  Here is what am curious that we can unite our physical layer tables too, why we can't define star in the physical layer? and why only in MDB? and what are the differences in the joints that we made in the physical layer as the layer MDB?
  I got tired of getting answers to these documents and in a few other online resources, but am not to succeed. Then, approach this forum in anticipation. Can anyof you help us to better understand these concepts.

  Yes, you need to (or is at least strongly recommended) to use complex joins in the MDB layer. I know that you can also use physical layers in the layer MDB, but I don't really know what happens when you do that and what are the consequences. I think I read once your knuckles are 'fixed' and the BI server is not to choose between the joints.

  So the idea is: set the 'true' joined in the physical layer using physical joints and define complex joins in MDB layer and let the BI server decide what physical join, it should use.

• Just updated - now made containing ALL the physical memory - late - more

  I've just updated to the new version - (automatic update) of Premiere Pro - and base renders, who once flew on my computer this morning, are now draining all of the physical memory system - and a break because he's so more enough memory 16 gb.

  Before the automatic update - everything worked perfect.

  I even split the video into segments 2-3 minutes and it does the same thing.

• Copy the physical to virtual servers

  Hello

  I'm trying to vrtualizing our server Park.  All domain controllers and file servers are running under two hosts of ESX3.5i.

  We also have a member WSUS and AV win2003 server and an intranet server Debian with a lot of other running services.

  It would be a lot of work to reinstall these two, and if I remember correctly, I heard about the tools that can "virtualize" a physical server.  I think it was by starting a kind of client CD and connect as a 'customer' to ESX and disk image of the physical machine processed and copied on ESX as a virtual machine.

  We got ESX Server 3.5i with our new Dell PowerEdge servers.

  1. the process of 'conversion' above would be possible for us to our win2003 and debian servers?

  2. What is the success rate, and a lot of traps in this process?

  3. do we need to buy more licenses of VMW to convert these two...?

  Thank you very much for the comments on this

  concerning

  Tor

  Simply use VMware converter to convert the machines. No, I converted a Debian machine before, so perhaps someone else could chime in on this. You will have no problem with Windows-based computers.

• The physical layer Naming Convention

  Hello
  
  I am trying to install my physical layer and see the reference to name them correctly. When I look at the examples of sales, I see they use A01, A02, etc..
  
  But I have others indicate that I should their name:
  fact_sales
  dim_customers
  
  Anyone has any good advice on how to put in place a naming convention that is appropriate to the physical layer.
  
  And that I should just using this naming convention in names for the alias tables?
  
  Thank you
  Kathy

  Use as
  SALES_F and CUSTOMERS_D

  _F made
  _D for Dimensions
  At the top of case

  For Alias, use DATE (W_DAY_D) closing

• Changing data in the undo tablespace or db Oracle buffer cache

  Hello
  
  I have serious doubt in the feature of oracle architecture, when a user issues an update statement, the data blocks are transported to the db buffer cache and where the data changes are made? Made a copy data block is stored in the cache db pads and the changes are made to the block in the buffer cache? or the copy of the data block is stored in the undo tablespace and changes are made to the blocks in the undo tablespace?
  
  In singles, the changes to the data blocks are make to the db or undo tablespace buffer cache?
  
  
  Thanks in advance
  
  Kind regards
  007

  Did you have a look to the Internet for the answer?

  In short, if a trial Oracle wants to update a record in the table, it does:

  -Read the record to be changed in the buffercache
  -Audits (the record already locked, is the update allowed)
  -Put the folder (called image before) in a rollback in the UNDO tablespace segment
  -Writing redo information about this change in the UNDO tablespace
  -Lock the record
  -Write the change in registration in the buffer cache
  -Put the change also in the redo buffer
  S ' sit and wait... (for a commit or a rollback)

  When are committed:
  -Release the lock
  -Empty folder of restoration since the UNDO tablespace
  -Write a record of this change forward in the UNDO tablespace

  When rollback:
  -Release the lock
  -Rinse the record changed the buffercache
  -Read the original value
  -Empty folder of restoration since the UNDO tablespace
  -Write a record of this change forward in the UNDO tablespace

  It of here, some more specific complexity when a checkpoint occurs between the change and the commit / rollback or redo buffer has been emptied for redo files

  Please any other s/n, correct me if I'm wrong...

• Shared pool larger than the buffer cache

  Hi all
  
  My database is 10.2.0.4 running linux platform
  
  No .of 2 cpu, RAM-2 GB
  
  SGA_TARGET wa set to 1 GB.
  
  Initially the memory have been configured as a shared pool around 300 MB and the buffer cache about 600 MB.
  
  When I questioned the v$ sga_resize_ops views I found some interesting results.
  
  Many operations and growth reduction were happened and the current size of the shared pool is about 600 MB and buffer cache is 300 MB. (this happened during last 1)
  
  I guess that the buffer cache must always be larger than the size compared to a shared pool. My assumption is right?
  
  Is it because of sql code using the do not bind variables resulting in growth shared pool? No relaods and radiation are almost ignored I think it should not be the case.
  
  Also no lock events listd in the top5
  
  I've also seen the 15% of the shared pool is marked as being of kGH:NO ACCESS, which means that the part is used for the cache buffers.
  
  Should I set the lower limit for the shared pool and the buffer cache or can I just ignore it.
  
  Thank you
  rajdhanvi

  You change your question now... your question was that he has sharedpool large size > buffer cache is acceptable... . Check your own second post... for your new question now is why pool continues to increase and partly used as buffer cache... the proof is given by tanel poder y what happens when EAMA is used... For the Kingston general hospital: NO ACCESS means that no one else could touch...

• What is the interaction between appellant VIs and subVIs using VI Server?

  I am student at the CLAD and one of the lines in the document preparation or here is the following:

  What is the interaction between appellant VIs and subVIs using VI Server?

  I know how to use the function "Call for reference" to call a VI, but not necessarily a Subvi. I thought a Subvi is always loaded with the calling VI and has nothing to do with the server of VI. What Miss me?

  Hi Bmihura,

  I think that this article will clear up how the VI Server works with subVIs called statically or dynamically.

  Call a VI by reference

• Get rid of the physical switch between 2 ESXi - Layer2 virtual servers between boxes

  Hello

  It's maybe a stupid question, but I can't quite understand the answer so I might as well ask.  I have two physical hosts of ESXi in my lab and for various reasons wish to eliminate the physical switch between them, but while retaining full vSphere functionality (HA, vMotion, DRS etc.).  Is there a switch virtual/Repeater product can I buy/use (deployed on the two ESXi hosts in a HA configuration) who can give me this feature?  I would then use Teddy ports on each ESXi host to talk to each other and additional natachasery as switchports to the outside world.  i.e. can I do this with a kind of multi-Vyatta router configuration?  NSX?  Must also support multicast.

  Thanks for your help!

  If you want to get rid of the physical switch, simply do not use it. ETH-cable to directly connect the natachasery of these two hosts of ESXi. If your NICs have the ability to auto-mdi (x), there is no something special. Some older NICs may still require cable crossover, but this is not necessary with new hardware...

• How do they interact between the stage and the classes?

  Hello
  
  I asked this question before, and all I got is 'Go back to reading beginner books', so I hope that someone here is willing to actually answer my question rather than brushing because they were unwilling to help...
  And Yes, I have read books on the topic and been through tons of documentation and not found the answer to this. I have 1 ActionScript and JavaScript experience, so this whole thing shouldn't be this hard.
  
  I am using ActionScript 3 in Flash CS3.
  
  My problem is the following:
  
  I need to know how to send commands between the stuff on the stage and stuff which is defined in a class.
  I had this problem for centuries and kept trying to find ways around it since so far I couldn't find help for her.
  
  For example:
  When you use a document class, how can I get the number of the current frame of the stage?
  Or using a class of documents, how can I access any object (such as a MovieClip with instance name) who has been on the scene with the IDE?
  
  Currently, to be more precise, I'm doing something really simple:
  Make a button work on my scene, which is not always visible. With AS3, which is not as easy more than before.
  So what I have now, is to create the button in the document class, used addChild and set it to alpha = 0.
  
  Now, when the stage reached specific images (i.e. those with labels, and I got this part understood), it is supposed to make the button visible. Then I can add stuff and event listeners, and I can understand this part myself.
  
  I do not know how to access the number of stage of the document class setting, so I put it in a script of frame in frame 1, but now this script cannot access the button that is defined in the document class.
  
  It makes me bananas...
  
  Please, here, can someone someone explain to me how can I make this work?
  
  I've seen many diagrams of the list of display and the object hierarchy, but none of this, explains how to USE effectively all...
  
  Thank you in advance to anyone who is willing to spend the time to answer!
  

  Well, first of all, I must say that AS3 is fundamentally designed to be difficult on purpose, this interaction between the objects is intentionally very strict. For this reason, I always use AS2 to all my basic work of Flash. AS3 is just much more involved, much tighter, much less forgiving... it takes a lot of experience with it before it begins to make sense.

  Now, I think I might have a few answers to your questions:
  Any DisplayObject instance (this includes any class of Document, which must extend MovieClip or Sprite instances) you can access the scene using the "stage" property

  However, stadium is probably not exactly what you want, you want the main timeline, which is a child of the stage. To access the main timeline, you can use the 'root' of any DisplayObject property.

  However, unless you have the strict mode off, Flash will let you just say 'root.myMovieClip' because the root property is of type DisplayObject, that is not a dynamic class (which means that you cannot add properties to it) and it has not built in the "myMovieClip" property, so he thinks you did a mistake. You have to "climb" the root as a MovieClip property, which * is * dynamics so it will allow you to try anything on this subject of reference (like AS1/2 does with everything.)

  So what this means is it should work from the inside, document you class:

  .myMovieClip (root as MovieClip)
  or
  MovieClip (root) .myMovieClip

  Either successfully make reference to a MovieClip you set on the main stage in the IDE and named 'myMovieClip '.

  Rather than set the alpha to 0, try the visible parameter to false. I think that this will disable all interactive events, where simply setting alpha to 0 it would still be interactive.

• Interaction between the two forms

  Hi all
  
  IAM a beginner to this Summit. I have a problem with the interaction between the forms.
  
  I have a relationship with the table where I have included for each line like this radio button
  "Select APEX_ITEM. RADIOGROUP (1, r.ID,'7 ') as P10_RG,
  r.ID,
  r.Ref_ID,
  r.Customer_name,
  p.Name as product,
  s.Name as Source,
  c.Name as country,
  of product p, requirements_maintenance r, source, country c
  
  so if I have a radio button on a particular line and you click a tab in the header, go to another form where I should be able to get details of the line I selected in the previous form.
  
  I tried several ways to get the values using javascript, but it grabbed nulls as
  $x('P10_RG_0').value but I do not get it.
  Please can someone me wat is the solution for this?

  Hello

  If your next page (ie the redirected page) is page no. 10

  "Select APEX_ITEM. RADIOGROUP (1, r.ID, 'null', null,'onclick = "document.location.href =" f? p = & APP_ID.: * 10 *: & SESSION.: REGION3: & DEBUG.:RP:P10_R_ID:' | r.ID |'") » ''") "

  and on page no. 10 have an element named P10_R_ID as a hidden item.

• How to set the join in the physical layer between the cube and the relational table

  Hello
  I have a data aggregated in essbase cube. I would like to supplement the information contained in the cube with data from relational source.
  
  I read the article http://community.altiusconsulting.com/blogs/altiustechblog/archive/2008/10/24/are-essbase-and-oracle-bi-enterprise-edition-obiee-a-match-made-in-heaven.aspx that describes how do.
  
  In this article, I think I have to define a complex join between any cube of essbase to my relational table in the physical layer.
  But when I use the Manager to join I am only able to define jooin between the tables of the source of the relationship, but not with the cube imported.
  
  In my case, I'm trying to reach the risk dimension in the cube based on risk_type_code (Gen3 members), with risk_type_code in relationship table dt_risk_type.
  
  How can I create this join?

  RelationTable.dt_risk_type = cube. "" Gen3, risk. "
