• Planning Via Weblogic cluster for load balancing

  We evolve our 11.1.2.2 Planning application on two physical servers as described in the documentation for EPM and the Weblogic console sees the valid cluster.

  Each server is used when it is not working, but how we can demonstrate that the two servers are certainly all load balancing when you use forms, business rules, and indeed any other thing.

  JConsole is a rudimentary indicator as to load the JAVA virtual machine and looking at newspaper planning could help if you know what to look for, but I would really like to know the details of a person who has perhaps done this before or who can guide me on the relevant documentation.

  The Oracle documentation, I found so far seems to take you far and then you drops.

  We are a site of Unix and are currently using a web server HTTP Oracle

  Thank you

  You can use Enterprise manager to monitor sessions between managed servers or the monitoring tool for apache (which is essentially what SST is running).

• Network of twinning with Port trunks to support the host ESX VShere 4 with several NIC for load balancing across a HP ProCurve 2810 - 24 G

  We are trying to increase production of our ESX host.

  ESX4 with 6 NIC connected to HP Procurve 2810 - 24G 2 ports; 4; 6; 8; 10 and 12.

  The

  grouping of parameters on ESX is rather easy to activate, however, we do not know

  How to configure the HP switch to support above connections.

  Pourrait

  someone please help with a few examples on how to seup the HP switch.

  Help will be greatly appreciated as we continue to lose tru RDP sessions

  disconnects.

  Best regards, Hendrik

  Disabling protocols spanning-tree on the Procurve ports connected to the ESX host is going to promote a recovery more rapid port. Similarly, running global spanning tree is not recommended if you mix some VLAN iSCSI and data in the same fabric (i.. e. you do not want a STP process to hang storage IO). Spanning tree on your switches, look PVST (or Procurve BPMH) to isolate the STP VLANs unique events.

  In regard to the load balancing is, by default (route based port ID) value algorithm requires less overhead on the ESX hosts.  You may not use LACP on the Provurve the lack of facilities LACP ESX. You must use "route based on the IP hash" sideways ESX and 'static trunks' on the side of Procurve. Unless you have specific reasons why your network need loads this configuration, I'd caution against it for the following reasons:

  (1) IP hash requires thorough inspection of packages by the ESX host, increasing CPU load as load package increases;

  (2) the static configuration puts switch physics rigid and critical ESX host port mapping. Similarly, groups of ports all will fail as the Procurve batteries for management only and won't be on switches 802.3ad circuits Group (i.e. all ports of a group of circuits must be linked to a single switch) - this isn't a limitation of the port ID routing;

  (3) K.I.S.S. love port ID mix of port ID, beacon probe and failover on the port assignments you will get segregation of the raw traffic without sacrificing redundancy - even through switches.

  I hope this helps!

• Configure load balancing NETWORK for Exchange 2010

  Hello guys.

  I need help. Where I work, we have a project where we configure Exchange 2010 DAG and some other stuff, and we have 2 ESX with 1 CAD server and a Server CASE/HUB too on both of them and that we want to use the NLB on these two hosts.

  I found this, and this is much like what we want:

  http://KB.VMware.com/selfservice/microsites/search.do?language=en_US & cmd = displayKC & externalId = 1006525

  So now our switch we want to create a virtual IP address for each of them, but we are not sure if we need to create a cluster on our servers for this.

  Did someone done this before that could give me some advice or contains information to make this work?

  Thanks for your help.

  Howdy,

  Am I was right assuming you want balancing two virtual computers CASE/Hub and NO servers DAG?  If Yes, then we are good to proceed... (if you want to do DAG servers load balancing, or if the DAG servers have all three roles, MBX/CASE/Hub, then Windows NLB is prohibited).

  You don't need to create a cluster as in MSCS or the Windows failover cluster, but do not create a pool of machines for load balancing.  You must install the components of Windows NLB on each machine virtual (VM Hub/CASE) and then follow the procedures described in this document: http://www.vmware.com/files/pdf/implmenting_ms_network_load_balancing.pdf to correctly configure the ESX host.  There are two ways to configure a WNLB, using the multicast and uni-cast (by default).  Uni-cast requires configuration changes side ESX (detailed in the document), multi-cast has some dependencies upstream network, mainly adding static arp entry in the router.

  Take a read through the white book (it was written by VI3, but the same thing applies in vSphere) and let me know if you have any questions.

• RV042 load balancing problem

  We have two network connections coming into the office. One is a private Wan, and the other is a WAN on the internet. We have a RV042 router configured for load balancing. We have our private WAN which includes Exchange and 6 VPN Wan1. On WAN2, we have a public IP address and home workers. Both connections are 5 Mg T1s and both have the ability to access the internet but only wan2 has a public IP (76.x.x.x) were as WAN1 has a private IP address. (10.x.x.x).

  Were now the problem lies is our new website based on payroll, system does not support load balancing. We have on one hand stop when we do pay (Tower load balancing off.)

  Now is it possible to use our computers to pay only one side? change the host file maybe? Or force a certain MAC address of use only the WAN1 or is there a better router to achieve?

  Any help would be appreciated

  Peter Labelle

  I don't have a RV042 and have had reference to the Administrator's guide:

  http://www.Cisco.com/en/us/docs/routers/CSBR/RV042/Admin/Guide/RV042_V10_UG_C-Web.PDF

  I hope these comments are useful. Perhaps you can comment and let me know if it works for you. Check balancing load and the binding protocol section.  These changes are disruptive... Please assume a failure during the change.  Not a long interruption, but the sessions at the same distance could be lowered.

  Out, you can use the protocol binding. This could cause some problems with the VPN client... you can try this after hours?

  For entrants, how customers and remote computers know the accounting software?  You are advertising this IP address via a link or another?

  If you are, then you can have a preference through one of the links.  If you advertise this IP address then you will not be able to provide a preference to a supplier of services on the other.

  Do please see the Administrator's guide and let me know your thoughts.  Sincere greetings and HTH,

• VPN3000 Load Balancing - synchronization of the Configuration

  I have found information on the configuration of hubs for load-balancing and realized that. I can't find any information on how the Member devices keep their configurations in sync. Is it automatic or is it necessary to update all members manually when changes are made?

  Dennis,

  Automatic synchronization of the configuration on the hubs is not possible. You must manually synchronize the configs.

• PIX / ASA - OSPF load balancing

  Hello

  I read the balance a route via OSPF equal cost load the PIX. It will send packages via per package, or is there another method for distibuting the traffic to the break following equal cost?

  Thank you!!

  Lee

  Hello Lawrence,.

  PIX 6.3 now supports the NLB using OSPF only (up to 3 default routes)

  The PIX can receive up to 3 doors by default (all the same metric) 3 different routes of entry, and

  balance the load on a per destination basis. Currently, there is no way the PIX to

  determine which carries a package will be sent to. You cannot currently use static routes

  for load balancing.

  The used hash algorithm is not simple, it is very difficult to determine which

  Route (next hop) a package will be given an IP Source and Destination pair. Basically,.

  the PIX takes the source and destination IPs (two 32-bit numbers) and axe in one

  16-bit unique number. Then the number of 16-bit (0x0000 - 0xFFFF) is divided into thirds.

  The first 1/3 goes to the door of entry 1, the next 1/3 goes to the door of entry 2, and the last 1/3 goes to

  Gateway 3.

  I hope this helps! If Yes, please rate.

  Thank you

• The implementation of hyperion IR application load balancing while 2 servers point to a DB?

  There is a DB production. Some time need to configure the load balancer for Hyperion interactive report achieve high availability.

  As know there are a lot of method to implement load balancing, want to know if

  given two machines virtual (each of them has its own application server), and two of them going to point to the same DB via shared Assembly called/U01 player.

  After the official documentations of oracle documented, there are scarce resources can refer to, any who knew this case of configuration before?

  Hello

  We have implemented this type of solution:

  (1) server 1: install and configure in usual way. Better to use different patterns for each product.

  When you configure Reporting and analysis framework services give repository location as shared drive location.

  (2) server 2: Installation of any product that has been installed in the server 1. While configure the database for the shared services registry point to detail diagram 1 server, it automatically configure the database for all the other remaining products.

  When you configure Reporting and analysis framework services give location of the repository as a shared drive which gave in Server 1.

  Make sure that the Shared disk is accessible from both servers.

  You can deploy applications weblogic Server from Server 2 by giving details of server 1. ensure that the weblogic Server 1 service must always be upward and running for Server 2 workspace to work.

  So if we set up the web server in both servers, then you must have load balancer and configure logical web address to this server for load balancing.

  If you configure only in one of the server, then this workspace server that url will act as load swing url.the problem with this is always THAT OSH must be running or workspace url will not work

• vShield 5.5 - load balancer - trying to implement the signed certificate

  Some background information for the context:

  vShield Mgr 5.5:

  -imported Root CA Cert and a CA-signed X.509 cert.

  -capable to connect to vShield Mgr with certificates of trust.

  VCD cells:

  -all certificates signed and imported

  -able to connect directly with certificates of trust.

  balancer load vShield:

  VM: vcloud.ourcloudnet.com (10.10.10.1)

  Profile: http/https, least_conn, 80/443, the members are the two cells of vCD

  We want to have a cert signed and approved for load balancer address (vcloud.ourcloudnet.com). I tried to follow the procedures described in the Administration Guide vShield 73 page, but I'm getting confused with the procedure itself. When he says "you can generate a CSR and get it signed by a certification authority." If you generate a CSR at the global level, it is available for all vShield edges in your inventory. ", which means generating a CSR to the Mgr level as opposed to the Edge level vShield vShield? I'm doing this all wrong?

  Need advice please.

  I understood the question. When the certificate is ready to be downloaded, I need to select Base 64 encoded instead of the DER encoded. This will allow me to see the signed certificate in the format plain text and then paste the contents of the certificate signed when I import the certificate in the edge of load balancer device.

  When I did that I also fell on another question I want to create a new discussion on.

  Thanks anyway for the help.

• vCO 5.5 high availability / load balancer configuration

  I do a planning for a new deployment of vCO 5.5 and I would like to take advantage of the new features for high availability, but documentation seems to be a little lacking in Department of load balancer. I hope someone knows the answers to the following questions using zero in on possible configurations for load balancing options:

  Calls to instances of vCO they state or can I use a setting of type stateless round robin for the configuration of lb or what do I need to support sessions?

  Is there a health control end point which I can query the load balancer to automatically remove service instances in a configuration active / active failure? If there isn't a specific is a good audit can be done to create a service to act as a health check?

  Did he already works with a configuration similar and willing to share their experiences?

• Hyperic HA does support load balancing?

  Hello
  
  We try to implement architecture Hyperic high availability based on JBoss HA and distributed cache EHCache. Our version is 3.2.3 EE.
  The cluster configuration is quite simple with the HQ High Availability Guide.
  Thanks for this guide and the esayness of the configuration of the feature!
  
  My first question was, the agent, what server IP should I use? I put with node 1 and other agents with node 2
  = > the synchronization between nodes works very well.
  
  Therefore, I have some additional questions.
  
  1 / can I have a single point of entry for agents with some load balancing and failover capability?
  For example, if an agent is sending information with the Node1 and this node breaks down or the server is restarted for maintenance purposes, the agent information will be lost.
  
  2 / same question for the application, can I have a single point of entry URL with some load balancing and failover capability?
  
  Thanks for your help.
  
  Nicolas.

  HQ Enterprise HA for failover, but do not support for load balancing.  You will need before your HQ multiple servers with a load (software/hardware) balancer which will relay agent to a live server.  The load balancer must be staged all agents in a single node of 'master '.  If this server is unavailable, another server will automatically become the master node and agents should be redirected to this node.

• OIM/OAM 11 g load balancing

  Hello
  
  I want to configure a load balancer for OIM/OAM 11 g access servers. Please let me know the steps or provide me with any document if someone.
  
  Thanks in advance,
  
  Srikanth

  Hello
  You must use Oracle HTTP Server (mod_wls_ohs) for load balancing between the OIM/OAM and Web tear. Please see this link http://docs.oracle.com/cd/E17904_01/core.1111/e10106/imha.htm.

  If you want to use load balancing between OSH and the user using a Virtual host/IP then you have user or traffic Director/HA Proxy Oracle hardware load balancer.

• Difference between the Port ID of the load balancer and MAC?

  There are three strategies for load balancing in 4.0 (one more now in 4.1):

  Function hash IP route

  Route based on the originating Virtual Port ID

  Route in function interference source to the MAC

  I think that I understand perfectly the "IP hash" and how it relates to switches, but what really is the difference between 'source MAC' and 'Port ID'?

  They seems both to do something very similar, which is attached a VM to a physical network card. Why someone should choose the CBC MAC and why the Port-ID? Is there a difference in the way that traffic will extend that could be interesting, when you do a design?

  Hello.

  To simplify, to really all boils down to the formula used to distribute traffic natachasery.

• Using 2 vNIC load balancing?

  Hi all

  I was wondering if I attribute to a vNIC VM 2, there will be no tolerance of failure/load balancing on this configuration? We have some Symantec devices on whitch it comes as a recommendation.

  Thank you!

  In this case there will be load-balanced, no?

  Not really... If you comment using a vNIC enormously and one not one alone, traffic is not get distributed also on the bears from the vSwitch.

  There are other policies available that might better integrate according to the virtual computer tasks to perform. A virtual file server with a vNIC could better to run on IP hash strategy. In this case, the IP addresses of the communication partners are used to spread the load (at the level of vSwitch). As a file server usually communicates with more than one host, you get a better distribution of the load.

  If you have smart switches that support a protocol for load balancing you can use.
