The order of failover and load balancing

• Override the order of failover vSwitch

  Hello

  Do people know if it is possible to script the ticking of the box 'Ignore the order of failover vSwitch' as found on NIC Teaming tab a GRPE of ports and if so what the appropriate code would be?

  By using the following code (as part of a larger configuration script):

  $net = get - view (get-($esx) USER.USER).configmanager.networksystem

  $pgname = 'service Console '.

  $mgt = $net.networkinfo.portgroup | where {$_.} Key - like "service"} ' "

  $spec = $mgt.spec

  $spec.policy.nicteaming.nicorder.standbynic = $nics.mgmt2

  $net.updateportgroup ($pgname, $spec)

  generates an error when you try to set the standbynic (the last line above). The message that appears is:

  Property 'standbynic' is not found on this object; Make sure that there is and can be defined. On line: 1 char: 34 + $spec.policy.nicteaming.nicorder.s & lt; & lt; & lt; & lt; tandbynic = "vmnic1.

  However, if I manually checkbox on the portgroup appropriate before running the code, then all is beautiful and groovy and the desired effect is reached (vmnic1 becomes the nic of the day before). I have checked the documentation of the API and can't see anything obvious that relates to the definition that I need to change.

  Any ideas?

  I don't know what you have in the $nics variable, but there are 2 problems that I saw.

  (1) the similar string should have asterisks in there

  (2) you must first assign the object to the nicorder property

  Something like that

  $net = Get-view(get-view($esx).ID).configmanager.networksystem
  $pgname = "Service Console"
  $mgt = $net.networkinfo.portgroup | where {$_.Key -like "*Service*"}
  $spec = $mgt.spec
  $spec.Policy.NicTeaming.NicOrder = New-Object VMware.Vim.HostNicOrderPolicy
  $spec.policy.nicteaming.nicorder.standbynic = $nics.mgmt2
  $net.updateportgroup($pgname, $spec)

• DBMS_SCHEDULER and load balancing works

  Hi all
  
  I have a question about the DBMS_SCHEDULER jobs package.
  
  We handle about 100000 records in a package and it takes a lot of time.
  If we intend to divide the 100000 records in 5 batches of 20000 each and treat them at the same time.
  
  For this we intend to schedule 5 jobs using the DBMS_SCHEDULER package.
  These 5 jobs will be subject both to the database.
  
  Now the question is, if we submit the 5 jobs at the same time, will oracle load balancing.
  Suppose that if 5 jobs are treatment and 2 are fine and he finds jobs 3,4,5 are waiting for resources, then these jobs will be kept on hold and it once the tasks 1 and 2 are made, will begin work pending in the queue.
  
  Receive your answer on that.
  
  Thank you
  Madhu K.

  How you treat these records? 100,000 records isn't really a high volume of our days.

  I'm not aware of anything in DBMS_SCHEDULER who will do what you asked, the jobs will run as planned and consume the resources that they require or wait until resources are available.

  By breaking the lot well you will find that your treatment time increases (for example if you have managed to increase the claim within the system), you must identify the bottleneck in the current process before going on the road that you are trying.

  The first step would be to see if there is anything in the process, you can adjust (see what consumes system resources and see if you can make more effective) and go from there. Possibly using AWR/StatsPack, TKPROF, etc... Depending on your version and that you have a license.

• Double connection ISP and load balancing

  Hi all

  I have the Cisco 2911 router k 9/s with 3 GB ports. I have also two different ISP connections, all have two different available bandwidth (one is asymmetrical, else a symmetrical).

  What I want to achieve is to ensure the balance of Nice load between two ISPS for all PCs behind the NAT device.

  What I know so far, it's that I can use CEF or PfR/REL. For both of this technology, I have some doubts.

  CEF: distributes the network load between the two connections based on sessions (which is good, because I strongly to use tools like Skype or Lync for audio/video conversations). However, what is happening, when I get on one of the ISP connections broadband bandwidth max? He's going to choke for 50% of the connections? Or it will detect the use of bandwidth and to force using second ISP?

  PfR/REL: as far as I understood it resolves my concern regarding the use of the connection, but what happens to the session? Should it also be based on this mechanism? As you know that it is very important for audio/video connections.

  Are there other tools that can provide these load balancing? I know DAB, but I don't want to decide manually, where each service (e.g. http or ssh) will have to go. I'm looking for something more automated.

  Thanks in advance for any help.

  Hello

  I assume that you have a static route for the subnet 213.192.65.0/24 on top of the output and with the combination of order

  network default IP 213.192.65.105 213.192.65.105 IP address is installed as a default gateway. What is the #2 ISP?

  If so, it explains why he always goes on ISP2 only.

  http://www.Cisco.com/en/us/Tech/tk365/technologies_tech_note09186a0080094374.shtml#flagging

  Just remove the config:

  Noneip default-network 213.192.65.105

  Noneip default-gateway 213.192.65.105

  Then again check the routing table:

  SH ip route

  Hope it helps.

• Where to configure clustering: on the web server or a load balancer?

  Hi all

  a few installation questions. I read on clusters and where to set up the pool. My main goal is to reach stickness session, session failover. but I'll ask them later when I clarify below.

  If my installation is

  -> Cluster WebLogic Web server, I need to install the cluster weblogic web server plugin.

  If my installation is

  Balancer load-> cluster WebLogic, I need to configure the LB, cos the LB must meet certain criteria.

  My planned Setup is

  Webserver-> LB-> cluster WebLogic. the weblogic balancing is done at LB. I'll have to set up the LB to balance to the cluster.

  I think I'm NOT configure the weblogic on the correct Web server plugin?

  Configuring the web server is obviously a proxy directly through the lb.

  So my next qn: the configuration to the LB is to balance the weblogic cluster OR a list of all the backend .jsf page server? Assuming that my application launch page is a jsf page. Enjoy your advisor.

  (a) you have little sticky on LB. On the Web server, Weblogic Plugin will take care of permanent sessions.

  (b) Yes, you need to add to your weblogic.xml in the application. There will be no conflict. However, your heap memory usage will increase as you could store session information on two servers.

  "Circumstances and considerations should I need a LoadBalancer in front of my weblogic cluster? --

  The main reason you would use a load balancer is to keep the VIP for your application. He would charge the balance between the weservers. Also usually SSL is stopped at the level of load balancer. It helps you reach cross clutser replication etc... You can read this document... Failover and replication in a Cluster

• NIC and load balancing

  Hello

  I have a new server ESXi 4.1. I currently have a cable connected to one of the two network adapters. When I put in place the management network, I selected the connected NETWORK card and left the other disconnect and deselect (via console settings directly on the physical machine). If I look at the network through vSphere Client cards, that's what I see: http://pix.sonhult.se/vmnics.png.

  What will happen if I connect another cable to my second NETWORK card? Will it set a new IP address for this NETWORK adapter? Could I have the load balancing or redundancy somehow?

  Thanks in advance!

  What will happen if I connect another cable to my second NETWORK card? Will it set a new IP address for this NETWORK adapter?

  Once you have plugged the network cable to your physical switch, you must assign to the vSwitch too. Once you do that the workload of the virtual machine and the management port will - by default - load-balanced in alternate way, which means that the virtual ports are distributed on the physical network interface cards.

  There is no need to assign an IP address any. An IP address is assigned only for the management port and the virtual machines within the guest OS.

  Could I have the load balancing or redundancy somehow?

  Yes. As mentioned above, this will happen automatically once you attach a second NETWORK adapter to the vSwitch.

  See http://www.vmware.com/files/pdf/virtual_networking_concepts.pdf for more details.

• Correct settings to use Smart Connect and load balancing?

  Hi guys

  I have a question, the answer of which I was not able to find explicitly, so I hope a quick fix OK / not OK for you:

  I would use tri-band technology provides the R8000, i.e. to activate Smart Connect / load balancing. Is - it only works Ghzs 5 band, or the router can also connect clients on the 2 Ghz bands?

  If this is true, then I need to give the strip of 2, 4 GHz the SSID the same 5 Ghz band, correct?

  Otherwise, if it only works in the 5 Ghz bands, I could keep the SSID distinguishes?

  Thank you

  Balancing of resources between the two radios. 2, 4 GHz band vs a single radio, the two radio channels in the 5 GHz band.

• How can I determine the order of firstname and lastname?

  I get the name of the contact with the following code.

  BlackBerryContact contact = ...
  String[] name = contact.getStringArray(Contact.NAME, 0);
  String firstName = name[Contact.NAME_GIVEN];
  String lastName = name[Contact.NAME_FAMILY];
  

  But I can't determine the order - "full name, first name" or "first name, last name.
  With my Bold 9700, it can be configured in the Options > language and text input > name display, but I couldn't find a way to get the setting from java code.

  Please help me.

  There is no API for this setting. If you see as important, you could offer it to your own parameters, otherwise just go with the standard.

• The virtual machine failover and restart with vSphere HA time

  Hello

  What factors would affect the time required for vSphere HA to computers failover virtual to a host failed to another active host in the cluster? It would be important how much space drive by using virtual machine is or how big it is? Or who should not matter?

  Thank you

  It should not matter. HA initiates the failover and the powers on the virtual machine regardless of size. Note, however, that there could be a delay in time OS/App.

  Another parameter that can affect the failover time is the number of virtual machines being switched at some point. If you have more healthy hosts in the cluster, then VM failovers happen simultaneously reduce the failover time.

• The orders of billing and installation.

  I bought the version student and teacher of the 12 months prepaid of Adobe CC from a retailer and bought the good. I can't install all products; It says on my profile that the order will have 24 hours to treat, but it rained overnight. What should I do?

  I was also wondering if it's part of the problem: before you buy the 12 month plan, I've been on the Photoshop 30 day free trial, but this was linked to a different Adobe ID. So, I already downloaded and installed the CC app to my computer, which is linked to another account. However, when I bought the full version of student Adobe CC I linked it to my student email to prove eligibility. This does mean that I have to uninstall and reinstall the app CC, then bind it to my student account in order to install programs?

  Thank you

  Hello

  The prepaid subscription purchased through retailers was completed and filled.

  Please disconnect and reconnect to the application of CC desktop and it should fix the problem.

• Confusion in the order of line and statement-level trigger

  Hi can anyone tell me, if I create a trigger on the emp table as in order...
  
  BEFORE INSERTING... LINE LEVEL
  BEFORE INSERTING... LEVEL STMNT
  AFTER INSERTING... LINE LEVEL
  AFTER INSERTING... LEVEL STMNT
  
  
  that will be the order of execution of the trigers?
  How oracle will decide order?
  
  Please give me some documents related to the order of execution of triggers... thnx in advance... !

  PC says:
  Hello.. Obtained response on the order of... but 1 weird point I m feeling that

  in the case of, before insertion... stmnt fire triger level 1 then insert before... line.

  but in the case of after insert... fireing level trigger line then 1 after insertion... stmnt level...

  can you explain this also...

  Why is it so strange.

  You have a statement that you are running.

  The first possible thing is that you are 'before' the statement.

  The next thing that is possible is that the statement is executed for each line.

  So for each line, there is a 'before' to each line and a point "after" each line.

  Once the statement is executed, you are 'after' the statement.

  Thus, it makes sense the statement triggers surrounds education and line triggers are education, and of course 'before' comes before 'after '.

• Defining the order of assessment and the dimension of the reorganization

  Hi, I was going through the pdf of hp admin and I have some doubts
  What do you mean by setting the option of evaluation in the planning of the means, and why it is recommended to select only one dimension (order of evaluation of adjustment)
  
  in the section "on the reorganisation of the Dimensions", it was mentioned on the order of aggregation rare dimensions before no aggregatin ones, what are these two types and also he was supposed to organize the scattered dimensions in order of more scattered members in less scattered members but is not the other way around I mean depending on hour glass order should be less rare for most sparse dimension and attribute in the end
  
  the difference in setting evaluation order and reorder dimensions, is what exactly?

  Reording dimensions defines the order of the dimensions in essbase, rearrange the dimensions can be part of the optimization of the database.
  The definition of the order of evaluation is more to do with how the dimensions are evaluated in shapes, so if the account is set to be first, then the properties of the type of the data member account will be used first, for example if the Member has the percentage value then Member will be displayed as a percentage.

  See you soon

• Question of the order of events and functions

  Hello

  Sorry for the stupid question, but I'm working on something big and I would hate a small rock to thow me off in the end.

  So here it is:

  I not know how to operate the functions-> if you have:

  function function1() {}

  function3();

  }

  function function2() {}

  }

  function function3() {}

  }

  function1();

  function2();

  First runs function1 and function2 and function3. Is simple baptisms the function1 + everything it has nested functions again from the top to the bottom, then function2 etc.

  OK, so now I have this situation:

  If you have an INTERNAL component that is in the MAIN component. If you addEventListener (FlexEvent.CREATION_COMPLETE, test) inside of the INSIDE (class of the function of construction in my case) and also add the same event listener once again inside but the MAIN ingredient such as:

  public void main_creationCompleteHandler(event:FlexEvent):void {}

  inner.addEventListener (FlexEvent.CREATION_COMPLETE, test);

  addElement (inner);

  }

  Then you will have 2 event for the same event listeners. First one written to the INNER component will run, and then it will run in the MAIN component.

  Now if I set many many functions in INNER creationCompleteHandler, will all 100% complete before the creationCompleteHandler to HAND work?

  As I tested it, it looks like each treatment must be 100% made to the INNER creationCompleteHandler before it passes to the creationCompleteHandler of HAND.

  Can someone confirm that flash/flex works like that? Thank you!

  Hi Alex, guys,.

  so, I would like to summarize the question and if we can just say Yes or I guided even what is Yes, then there is no confusion

  Here are 2 scenarios:

  1) 2 headphones are added to the same same thing e.g. CREATION_COMPLETE - one for the component and the other to the container.

  It works like this:

  un) pane-> creationCompleteHandler starts to perform its functions/activities

  b) containing-> creationCompleteHandler starts to perform its functions/activities

  The question here is: will a) be 100% full before before flash moves to b) or b) could happen sometimes some time one) is running?

  Note: Yes this means a) will be 100% complete bofore b) occurs.

  2) for the second scenario allows to take 2 different events INITIALIZE and the FlexEvent CREATION_COMPLETE and add the listener both in the component only this time, so we do not complicate things.

  It works like this:

  un) pane-> initializeHandler starts to perform its functions/activities

  b) pane-> creationCompleteHandler starts to perform its functions/activities

  The question here is the same: will a) be 100% full before before flash moves to b) or b) could happen sometimes some time one) is running?

  Note: Yes this means a) will be 100% complete bofore b) occurs.

  Thank you very much

  (1) flash is currently single-threaded, so a Manager will end before the end of another Manager for the event itself. The processing order is not guaranteed and since your handlers are listening for the event attached to the same object, that it is imprudent to write code that depends on the order in which these handlers are called. Adobe are working to multi-threading the flash plugin, in the future any order that may now exist differrent in the future and any treatment that depends on a single completion handler until the other is called can also fail in the future because a multi-threaded player could activate the two managers simultaneously.

  It's nice to have answers Yes/No, but only if you want to write poor code that can work, by accident, until something changes that you have no control over.

  Do not write code that depends on the order this event handler is called for the same event.

  (2) initialize occurs before the complete creation. The answer is Yes.

• What is the workflow to compile and load an external class to a runtime library?

  I have a set of classes (with a few large incorporates) I want to only load one by one during execution as needed.

  I think I need from each of these classes compile into a separate SWF file and use the Chargers available there to load and link to them dynamically while running (I'm on the right track so far?).

  I rose a bit mixed in details, so I just want someone to give me the rundown on this operation base, get the right termonology, and if you have a reference to the tutorial just do, so much the better!

  I use flex builder, and this should be used in a flex application.

  Thank you!

  David

  There is a Flex Library Project project type. If you create the library for each dynamically loaded block.

  And you can use the loader to load.

• WITH the ORDER BY clause and bug SDO_GEOMETRY?

  I'm having a problem using SDO_GEOMETRY in a WITH clause. Specifically with ORDER BY. I'll show a shortened version of SQL here. I'm doing something wrong or is this a bug?
  
  It works:
  

                       SELECT 
          loc.location_id,
                      SDO_GEOM.SDO_DISTANCE(cent.lat_long, 
                      MDSYS.SDO_GEOMETRY
                      (
                      2001, -- SDO_GTYPE attribute: 2 in 2001 specifies dimensionality is 2.
                      '4326', 
                      SDO_POINT_TYPE(-78.6386145, 35.772096, NULL),
                      NULL,
                      NULL
                      ),
                     0.01, -- tolerance
                      'unit=mile') result_center_distance
                      
            
                       FROM location loc
                       JOIN centroid cent ON loc.centroid_id = cent.centroid_id
           ORDER BY result_center_distance

  After the statement select in a with clause, this does not work, which gives an identifier not valid "SDO_GEOMETRY" ORA-00904:
  

  WITH location_distance AS
  (
                       SELECT 
          loc.location_id,
                      SDO_GEOM.SDO_DISTANCE(cent.lat_long,

  This is a bug. But it is set to 11g R2. Note that this is not a space bug, but a bug in generic compilation.
