• 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.

• The order of failover and load balancing

  Hello

  I have the following scenario. An ESXi with 4 Gbps vmnic. The questions are:

  (1) if I have a group of ports configured for 'Route based on the original virtual Port code' in the policy of balancing load, and for the same port group I the option button 'Override switch failover command"checked, where I set up 3 of the active adapters vmnic, as well as the other vmic remaining as unused adapter, the ESXi uses the policy that I have configured (in this case 'Route based on the original port code') between the three vmnic load balancing marked as active? Or he uses them in the order that they appear in the section active cards?

  (2) Suppossed, I configured the four physical switch ports in an etherchannel group to use 'Route based on the IP hash' load balancing policy. In this situation, then I configured for a certain group of port to only used two active adapters and two others as unused? In this case, ESXi should balance the load using the method hash IP but only in two active adapters? Or it is a misconfigiuration and I should not configure my nic teaming in this way?

  (3) the official setup guide says "NOTICE on IP requires the physical switch be configured with etherchannel. For all other options, etherchannel must be disabled. ». How can I I configured my virtual network, if I have a few groups of political ports based on the hash of the IP to use load balancing and another uses 'Route based on the original port code. This is the case when I for example have two management ports using the same vSwitch with four vmnic (where they are configured as an Etherchannel in the physical switch). I would port one or several groups for virtual machines that use the IP of the hash method of balancing the load and vmkernel ports por management uses only a single adapter active with no back and as "based on the source port ID" load balancing as best practices said.

  Now, the four vmnic is the same for all traffic. The physical switch ports must be configured in an etherchannel group because certain groups of ports will use the method of IP hash, but others are not. The configuration guide I said SHOULD NOT use etherchannel if I won't use the hash IP method, but I'LL use it, but only in groups of one or more ports.

  Maybe I do not share the same vmnic from this situation.

  Finally, it's a philosophical question. What is the difference between 'The route based on the source port ID' and the 'road based on the source MAC Hash' load balancing policy? What is the purpose of the second? It is assumed that if I had two different MAC address in a virtual machine, it would be because I had two different virtual cards inside the virtual machine, which would be connected to two different port ID in the vSwitch, I can use the first strategy (based on the original port code). In other words, which would be the case where I had the traffic entering the same vSwitch but port ID with different source MAC address, so I should chose the method to distinguish the Source MAC address load balancing traffic?

  Thank you.

  Guido.

  (1) as long as you override vmnic only and don't change the policy for this group of ports, he uses the policy configured at level vSwitch and use the selected interface 3 with this policy

  (2) it should work, I don't think it's a problem for the switch receive packets on a subset of the aggregation. I do not think that Etherchannel is supported (IIRC, it is a Cisco proprietary protocol, VMware only supports LACP passive, which corresponds to the Port channel world Cisco.) Trouble me if I'm wrong!)

  (3) I think that's all right, as I have explained in 2), there is no special negotiations with the consolidation of VMware, the important thing only I know is to configure the port on the side of the switch channel if you decide to use the IP hash (that will lead to important questions)

  4) (self labeled) I think it may differ in some cases individuals, as when the operating system use the same MAC address for both NICs (aggregation in-vm) or if you advertise several MAC address for the same network card (ESX in a VM for example would make for its VM). Such cases differently affect this setting.

  That is the right question, and I'm curious to know if someone wants to develop on it!

• 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.

• 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.

• Handling of load-balanced connections Sonic MQ

  Hello
  
  We have successfully connected to a single broker Sonic WebLogic, but we now plan to connect using a factory of (foreign) connections which is load-balanced, i.e. Specifies several brokers.
  
  I have read the Sonic MQ Application Programming Guide and noted that...
  
  "Any broker in a cluster can redirect incoming client connections to another broker in the same cluster for load balancing purposes. Load balancer must be configured on the broker. The client must also be configured to indicate that it is ready to have a connection forwarded to another broker request. »
  
  It indicates a client should call:
  
  ConnectionFactory.setLoadBalancing (true) before calling the createConnection() method.
  
  Given that I use JMS wrappers I do not have the ability to do that, can you confirm if this is the default?
  
  Also if you know traps around this scenario I would be grateful for pointers until we test this out for good.
  
  Thank you very much
  
  Mandy

  I think that the res-Ref wrappers can allow invoking extensions, but they must be exposed via an interface (cast to the interface from abroad). Sonic MQ can provide configurable load balancing behavior as well.

• Network [vSphere 4.1] load balancing and failover vMotion

  GoodMorning everyone.

  I have some doubts about the configuration of the network for vMotion in vSphere 4.1

  I know that I can activate a single portgroup VMkernel for vMotion on the single host, but can I have this portgroup in a vSwitch with two or more physical NIC attached.

  Currently, I managed to have a vSwtich with vMotion and management of trade wth two NICs (see attachment).

  Both NICs works very well with the recovery for both exchanges.

  I would switch to a vSwitch with multiple network cards and I have some doubts.

  It seems that I could configure it... but the load balancer for vMotion supported on vSphere 4.1?

  And also, have the protgroup of vMotion in a switch with several network cards, is there a way to check what physical nic is currently used by vMotion?

  I am currently under a license from the company.

  Thank you all for your help.

  vMotion for vSphere pre 5 does not support Multi-NIC, in vSphere 5, you can configure several VMKernel enable vMotion and select different Nic Active and load balance between the two vmnic, but unfortunately not in vSphere 4.x

  For the management of ESXi, if you set active on both network adapters, you not to cross any active advantage / standby because it will only use on vmNIC, unless there is still a failure... but 1 vmNIC just because bandwidth is usually not a problem for the ESXi management only.

  So the answer: upgrade to vSphere 5 for multi-nic vMotion and don't worry ESXi management as an active NETWORK card is more than enough bandwidth,.

  Here's a YouTube on the Multi-NIC vMotion http://www.youtube.com/watch?v=7njBRF2N0Z8 configuration

• Client based in 12 G load balancing

  We have a JDBC configuration against an address scan with client load balancing enabled.

  Example:

  JDBC:Oracle:Thin:@(Description=(LOAD_BALANCE=on)(Address=(Protocol=TCP)(Host=xxxxxxxxxxxx.de)(port=xxxx))(CONNECT_DATA=(service_name=XXXXXX)))

  What I understand of Diference between Client-side and Server Load Balancing If you do not use the server load balancing, you can bypass by connecting the service that identifies a particular node of RAC name.

  
  

  My question is, if you have a connection pool object this configuration and if the name service maps node to goes down, what happens to the connection connection pool?

  
  

  Issue 1) Don't scan address switches to the available according to the name of the service node, then the JDBC driver on the client must file all embusked connections and reconnect the available node? or is all the agnostic client failure of node on and all the old connections available in the pool are available for use?

  
  

  
  

  The client side or server balancing side basically works for the same purpose. The difference is that you do not have all the customers to reconfigure then change something in the environment, such as adding or removing a node such as the side server.

  Answer your question...

  If you mean the shared server architecture by connection pool, the shared server session connected to node 1 will die and everyone shares this session should log. Failover is not automatic, you must specify the failover clause in the JDBC or TNS connect string:

  TEST_TAF =

  (DESCRIPTION =

  (ADDRESS = (PROTOCOL = TCP)

  (HOST = rac - scan.example.com) (PORT = 1525))

  (CONNECT_DATA =

  (SERVICE_NAME = test)

  (FAILOVER_MODE = (TYPE = SESSION) (METHOD = Basic))

  ) )

  Or if you use failover and load balancing services you set failover described below:

  for 12 c: srvctl $ add orcl db-test - oel6vm1 favorite-available oel6vm2 - tafpolicy BASE - failovermethod SESSION service service - failoverretry 5 - failoverdelay 60

  for 11g: $ srvctl add service d orcl if test - r oel6vm1 - oel6vm2 BASIC EI SESSION m - z 5 AW 60

• With view 5.1 load balancer

  Hey all,.

  I have a question about to lift our load balancing program and perform in our view environment 5.1.  I followed the article KB 2020913 to get our servers view running with SSL certificates.  I'm doing our load balancer in place and I keep getting errors in SSL certificate.  Here is a brief summary of our facility.  I have two servers to view (VCS1 and VCS2) connection with our internal certificate authority SSL certificates.  There is our program of load balancing.  When you use VMware View Client and go to the view.company.com address of the load balancer, I get "pipe in the certificate name is invalid or does not match.  I click on 'See the certificate' and it is to show the certificate of one of the connection view servers.  A I mess up something with the installation program, or have I missed an obvious solution?  Any help would be appreciated.

  Thank you

  -Kyle

  Hello

  It is the expected behavior. With SSL, the certificate name is checked by report specified by the client host name.

  There are two ways to deal with this. If you are using certificates with another subject of your load-balanced alias name, it all will work.

  for example if you have some certs on each connection to the server (or the Security Server) with the names cs1.myco.com and cs2.myco.com but customers do you think users will connect using a load-balanced alias view.myco.com, then by ensuring that each cert has another name of subject of view.myco.com then the hostname match control work.

  See KB. VMware.com/kb/2006751 for more information.

• Cluster without a load balancer?

  Two interactive servers FMS can work this way:
  1. they both serve the same FLV VOD on both machines
  2. where a single server gets X users connected, next user (X + 1) is routed to the next server
  3. There is no hardware for load balancing
  
  Is this possible and if this is the case, how?

  Yes, that's possible, but there is nothing integrated FMS to cope. You must write your own application to do.

  I like to handle this by building a little app that queries the service of administration of each involved server once per second or more, and retrieves his stats on the instances of the application I need to keep track of (we'll call it the 'load swing app". In this application, I include functions to loop through the statistical data for each server and determine which makes the most sense to send the following to customer.

  Client side, I connect first to the load balancer app, providing an application ID that I want to connect to as an argument in the call to the connect() function. Load Balancing takes the best decision of server and returns the host name of the target server. Then, the client disconnects from the load balancer and connects to the target host.

• Can I have load balancing for two ISP (PPPoE and PPPoA) on Cisco 897va connections

  Hello

  I have two ISP connection and I have Cisco router 897va, I want to have the load balancing for two ISP connection second connection is PPPoE connection and second is PPPOA (ATM) connection.

  It is possible to do?

  Thank you in advance.

  You can balance by TCP (the default behavior with CEF enabled) stream.  Alias a user turns off a pipe and the next user goes off the next pipe.

  Make sure that you use the nat with route map that matchers the output interface, then you just need two routes of equal cost default (a leaver each circuit).

• VPN on several ISP load balancing

  Hi all

  Please explaing on VPN load balancing based on a scenario where two Internet service providers are here. How can I configure vpn balance in such a scenario?

  Thank you

  Shijo.

  Hi Shijo

  What type of VPN connections you want to balance the load? VPN remote access right? You can essentially set up a cluster within your VPN to load device balanced local traffic, passing through the same ISP... but for a scenario with 2 different ISPS, this may seem a bit difficult... Just because of the fact that your vpn device will have two different IPs on the outer side and have to finish on two different interfaces... tracking and grouping two interfaces are difficult..., your VPN clients will point to a single IP address on the part of ISPS, and virtual IPs have in this case is difficult...

  Hope this helps... good luck...

• Cloud of Pod Architecture and load - single entry Point balancing

  Hello

  I'm looking at our DR put in place for our view environment and Cloud Pod Architecture seems to be the way to go. A question that has popped up and I couldn't get a definitive answer about whether it is possible to use the load balancing of certain aromas to maintain a single point of entry into the environment seen. I would be able to have a connection to the server discovers in A Pod and a login server in View Pod B and then stick a load balancer at the front so that users always connect through load balancing and view.domain.com, they will hit either login server? Would it not possible to use a Windows NLB for that?

  What I want to achieve is to build a second Pod from view in a different geographical location to complete our game existing upward at our headquarters. This new Pod will be alive and actively used instead of a traditional DR implemented whereby all will sit dormant until the sh * t hits the fan. We maintain a single point of entry into the environment and the user gets negotiated at their office floating Linked Clone correct, be it in A Pod or B. Pod

  I hope that makes sense.

  Of the questions let me know.

  Yes, it is definitely possible.

  We currently have a configuration of global namespace for internal and external access.  It appeared linked to a VIP we have on our load balancing programs (Radware currently).  This VIP points to our real servers on both sides.

  Then, we focus on Cloud Pod Architecture configuration dedicated or floating pools.  People can connect and hit one side or both.

  If you leverage GTM or Global Traffic Manager (Smart DNS Round Robin), she may ask the weight or restrictions so when people only struck one side of your data centers until he is not available and then it hits the other side.

  Do not forget that the Volumes of App and RDS Apps are not supported, just virtual offices.

  We currently have two pods between two sites, take advantage of cloud pod and built infrastructure in duplicate for each site to be isolated and independent.

  We focus also on DFS - R on Windows File Services to ensure that the data are replicated and synchronized between the two locations.  Then with the use of DFS Namespace we weight each side sort users to the Site a success files on file to the Site Services and vice versa.

  F5 also has an edition of Big - IP virtual that will work great and deploy GTM, LTM (Load Balancing) and MPA (Access Policy Manager) to work on both internal and external access for you.
