• order for load balancer

  Shut Down vRealize Automation

  The above document, I can understand the stop order appropriate such as recommended, except for the load balancer.

  If we use the balancer for vRA and IaaS Server device, we should stop the load balancer before step # 1?

  You want to stop the load balancer when no traffic has to travel. From some that I would be stopping last.

• 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.

  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.

  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

  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!

• 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.

• Cannot replicate session on weblogic cluster

  Hi all
  
  I try to simulate cluster weblogic on a single machine. But why my weblogic installation can not replicate the session to another server? I'm trying to listen to HttpSessionListener for any event (session create or destroy), but only one server to deal with this application for handling and create the session. the other doesn't. where is my wrong setting?
  
  and when I try to access Internet without session, the server is reactivated to manage demand. but when the session, have already asked will stick only to a server for each session, I try to use weblogic 9 and 10.3. the two behavior is the same.
  
  Here is my setup of weblogic:
  
  Manage the server:
  
  1 address (localhost:7004); name (ms1); machine (mcn1)
  2. address (localhost:7005); name (ms2); machine (mcn1)
  
  each session on the managed server object is serializable.
  
  and on each server to manage weblogic.xml:
  
  < wls:session - descriptor >
  < wls:debug - active > true < / wls:debug - active >
  < wls: persistent-store-type > back < / wls: persistent-store-type >
  < wls: sharing > true < / wls: sharing enabled >
  < / wls:session - descriptor >
  
  Cluster: Cluster mode messaging is multicast. I try MulticastTest and its working fine.
  
  Load Balancing: I create the new domain (localhost:7002) and use the weblogic proxy for load balancing. just copy paste documentation.

  The webserver plugin using the link session (or sessions).

  How does him choice of server is explained in the figure presented here: http://download.oracle.com/docs/cd/E11035_01/wls100/plugins/apache.html#wp113659

  Here you can see if a sessionid is presented that it routes the request to the primairy server. A server primairy and secondairy is chosen in the cluster on a first request.
  The format of the session ID is: JSESSIONID = SESSION_ID. PRIMARY_JVMID_HASH! SECONDARY_JVM_HASH! CREATION_TIME. The first part is used by the
  implementation session in WebLogic Server to search the customer HttpSession object in the context of tracking web application. Subsequent parts of the session ID
  are used to identify the primary and secondary servers for this customer in a WebLogic Server cluster and track time created for this session.

  When you make a server - this is when failover occurs - the secondairy server takes over the request. Now, you would probably see that a session is created on the other server.

• (Load balancing) cluster in obiee 10g implementation

  Hi all
  
  We must apply the clustering (active for load balancing) in our project. We use both analytical and bi publisher. You must also deploy Analytics/bipublisher in weblogic aimed SSO server.
  
  Now we have two machines.
  
  From now on, we did the obiee10g installation (installing, we selected the button 'Finish') on both computers. Could any body tell us how to implement w.r.t. clustering for weblogic.
  More to know...
  
  + 1. Is normal clusrtering method in 10g with oc4j server is different when deploy us application in weblogic server... ? +
  
  + 2. Can I use one of the two machines to create a shared folder and place the RPD to give the path in REPOSITORY_PUBLISHING_DIRECTORY or should I use a third machine other than these two machine..... ??? +
  
  Any help is greatly apprciated.
  
  Thank you and best regards,

  Hello

  1. do you have normal method of clustering in 10 g with oc4j server is different when deploy us application in weblogic server... ?

  A. Yes, that some difference.

  2. can I use one of the two machines to create a shared folder and place the RPD to give the path in REPOSITORY_PUBLISHING_DIRECTORY or should I use a third machine other than these two machine..... ???

  A. you can use both ways but note are all systems must be same domain only.

  I've implemented clustering successfully Setup for last week.

• 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.

• 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.

• 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

  hope you understood.

• Hyperion Planning11.1.2.3. Server load balancing

  We will install and configure Hyperion planning in the cluster environment. After you have configured the servers planning successfully how to implement load balancing. Do we need to use hardware or software load balancing. I have no idea on balancers load. We must use to configure logical address that points to the load balancer server but do not know how the load balancing server must be? Please notify.

  Install all along planning to Server1 products and configure them.

  Go to Server2, install only the planning and deploy using the same database.

  WebLogic will create 2 (Plannin0, planning of the depenses1) servers in single Cluster (using the Round robin algorithm).

  Thus, at the time of access automatically weblogic will redirect requests internally.

  Thank you

• Best way to HTTP in OSB load balancing

  Hello world
  
  We have a cluster of OSB and we must load balance HTTP requests on managed servers. Looking for info on OSB in load balancing, I found that there are essentially two options: use a hardware load balancer or a software solution like Weblogic HttpClusterServlet. For the moment, we have without balancer material available so we will have to take the option of software. I found a few articles on the configuration of HttpClusterServlet as http://redstack.wordpress.com/2010/12/20/using-weblogic-as-a-load-balancer.
  But I have a question for this configuration. If we use a managed server as a proxy HTTP requests between OSB as managed servers, what would happen if the server goes down? I think that one of the main objectives of a cluster deployment is to avoid a single point of failure, but with this configuration, all requests depend on the availability of the managed proxy server.
  
  Could you recommend a configuration of implementation of OSB load balancing?
  
  Thank you in advance,
  
  Daniel.

  Load Balancing in a cluster for http requests can be made using at least 4 different ways:

  (1) - use a hardware load balancer like F5 BigIP LTM
  (2) - use a web server with the plugin from weblogic to the cluster frontend
  (3) - use weblogic with HTTPClusterServlet
  (4) - use the DNS round robin - it works if you managed servers that run on 2 machines (say mach1, mach2) but on the same port. Client HTTP use hostname "mach" to access the URL and the dns has a resolution of names alternating Mach mach 1 and mach2 IP addresses...

  All options except (1) only achieve load balancing and not automatically failover all instances... Balancing load material has the additional feature to probe [sending periodic pings to targets], by which it can detect if the target resource is alive and do not send traffic to other nodes who are alive... That's why the hardware load balancers are worth their investment...
  other options may work if the client is encoded to a retry on failure... so on 2nd or subsequent attempt, the routing is done in the machine that is alive...

  For the options (1), (2)) and (3), you also need a redundancy of the system (material of load balancer, web server or weblogic) to avoid the single point of failure for load balancing... Balancers support material are usually deployed in redundant pairs to achieve...

• Http-plugin supports metric base load balancing? like Mod_OC4J!

  He supports balancing the metric-based in Oracle 10 g AS OC4J.
  
  It's a good way to spread the query load among OC4Js based on a metric which was reported by OC4Js.
  
  When load balancing based on the metric system is enabled, requests are routed between based OC4Js on the report of a defined metric, as the ratio of round robin, automatic relaxing... etc.
  
  
  WebLogic server HTTP-Plugin has similar features? Could experts suggest simiilar workaround (s) or solution (s) Please?

  It is a good idea.

  Since now, WLS have no metric based load balancing.
  For load balancing, you must configure the proxy servers.

  http://e-docs.BEA.com/WLS/docs103/cluster/setup.html
  http://e-docs.BEA.com/WLS/docs103/cluster/load_balancing.html

  Give them some pressure to release new features.

  My concern, metric according to load balancing is explicitly vital for most of the users using OC4J. Y at - it no alternative to measure loading WLS? As I can build module
  or plugin Web levels... of course raise this request to my sys development team exactly.

  WLS do support 3 types:-Round Robin load balancing, load balancing based on the weight & Random load balancing.
  In the near future, I guess they do not provide as metric base load balancing MOD_OC4J.

  If you like to take some tasks to measure, I sugget contact you your sales local oracle for assistance. They have probably you persuade enjoying service professinal anyway.

• 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,

• 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
