• How to check the webnode load balancing?

  Hi I know where my corrections are load-balanced in all nodes in my web.
  
  
  For example, I have 3 nodes of web (web1.example.com, web2.example.com, web3.example.com)
  
  
  How will I know if my new connections are routed to all nodes in the web.
  
  
  AND how do I know the number of connections from different nodes.
  
  
  Thank you

  Hi I know where my corrections are load-balanced in all nodes in my web.

  For example, I have 3 nodes of web (web1.example.com, web2.example.com, web3.example.com)

  How will I know if my new connections are routed to all nodes in the web.

  AND how do I know the number of connections from different nodes.

  Check Apache log files on each of the nodes (error_log * and access_log *) and you will find the entries you want.

  You can also get more details the software load balancing.

• How to configure OAM 11.1.2 the script load balancing?

  Hello

  I am currently setting up Oracle Access Manager to work with load balancing

  I'm doing this configuration:

  In fact, I did the configuration with my browser, and I'm looking to do the same thing with a script.

  Where is the configuration stored? Domain configuration file? DB store?

  Is there a command WLST to do this config?

  Concerning

  An excerpt from wlst that will do the trick:

  domainRuntime()

  name = ObjectName ("oracle.oam", "type", "Config");

  writeSig = ["java.lang.String", "javax.management.openmbean.CompositeData"]

  oamHostKey = "DeployedComponent/Server/NGAMServer/profile/OAMServerProfile/OAMSERVER/serverhost.

  oamPortKey = DeployedComponent/Server/NGAMServer/profile/OAMServerProfile/OAMSERVER/serverport"."

  oamProtKey = "DeployedComponent/Server/NGAMServer/profile/OAMServerProfile/OAMSERVER/serverprotocol.

  MBS. Invoke (name, 'applyStringProperty', [oamHostKey, StringSettings(oamHostKey,"__myhostname__").toCompositeData (StringSettings.toCompositeType ())], writeSig)

• Console Proxy doesn't work is not behind the edge load balancer

  I have a strange problem. I set up a load balancer with vShield Edge. Behind the load balancer, I have two cells vCloud. The Web interface works very well for users, but trying to connect a VMRC to view remote screen it displays 'connection' and then the session is disconnected.

  Then I stop the first cell and users can establish a VMRC connection again. When I activate the first cell once again, the web interface continues to work, but not the proxy of the console. Then I stop the second cell and now elements of the console working again.

  Any tips?

  Gabrié

  Have a similar setup and had the same problem.  Two things to check.  Go to c:\users\\appdata\local\temp\vmware- and open the last file vmware-vmrc - xxxx.log.  Towards the end, it should tell you why it's a failure.  For me, it was a conflict of thumbprint SSL, dating back to the different SSL certificates on the cells.  Also, be sure to vCloud Director Administration-Public address you have the right audiences VCD console address specified. To resolve the inconsistency of my mark, I just created a file certificates.ks a cell and then copied on the other cell and reran the script configures.  Good luck with VMware to help.  I opened a folder for this issue 6 days ago and have yet to get any help!

• See the connection to the server, load balancer & physical workstations

  We deploy a VMWare view environment and we use a combination of physical and virtual desktops.

  When install us the Agent to view physical workstations with the /V "VDM_VC_MANAGED_Agent = 0" settings. " This allows to specify the Server Manager to view to record the workstation during installation.

  So far we've just been specifying a connection view servers and everything was fine. But now we are getting our deployment and we want to ensure that we have the appropriate redundancy built in.

  If the server connection view that physical workstation is registered during installation fails, is grave view agent automatically knows to start watching one of the replica servers?

  If it isn't... We are keen to implement a load balancer between the workstations phyiscal on connection view servers. Are there problems with it?

  I found many articles balancer redundancy and load for VMWare View, but none don't talk specifically a load balancer between physical work stations with the agent of the view and connection servers.

  Take a look in the registry on the physical Machine, he must list all available connection brokers it.

• The side load balancing test server

  Hello
  Can anyone tell me about any test cases for server side in a 11.1.0.7 RAC load balancing?
  
  I have a 2 RAC nodes with either local_listener and remote_listener correctly (for load balancing server-side). For the test, I create a TNS to my side client that points to a single node of the PAP (a single ADDRESS entry pointing to node 1 of my CARS). So, this customer, whenever I log in, it always connects me node 1 I mentioned in the LMO. This means that server-side load balancing works jointly with the client side only load balancing and I would also add the address entered my TNS for the second node? If Yes, then how can I create a test case to check server load balancing?
  
  Thank you

• Any type of field to add Application Profile for the ESG load balancer? (REST API)

  Hello

  I am currently working on adding an application profile to a load on a GSS (edge Service Gateway) balancer. I am using the REST API to add the application profile, here is the functioning of the REST API that I am using.

  POST https://NSX-Manager-IP-Address/api/4.0/edges/edgeId/loadbalancer/config/applicationprofiles

  It works fine, but I can't add a type to the message body. Documentation, it seems there is no field to add the 'type' or the Protocol for the application profile as you can see below,

  < applicationProfile >

  < name > http_application_profile_2 < / name >

  < insertXForwardedFor > true < / insertXForwardedFor >

  < sslPassthrough > true < / sslPassthrough >

  < persistence >

  cookie < method > < / method >

  < cookieName > JSESSIONID < / cookieName >

  Insert < cookieMode > < / cookieMode >

  < / persistence >

  < / applicationProfile >

  Is there a way I can add a type or Protocol to the application profile (that is to say, HTTP, HTTPS, TCP or UDP)? Is there something I'm missing?

  See you soon,.

  Dean

  What is referred to as 'type' in the Web user interface, is actually called 'model' in the API.

  Here is an example of API for the TCP type below

  applicationProfile-3

  testAPI

  fake

  fake

  fake

  The simplest way to understand the API call:

  . Create it on the Web interface

  . Discover the xml do a GET "https://{{nsxmanager}}/api/4.0/edges/edge-xx/loadbalancer/config/applicationprofiles.

• What load balancing algorithm using the LRT224?

  I was wondering if anyone knew what algorithm of load balancing the LRT224 use since I can't find it anywhere and the telephone support line does not.  It is very similar to the RV320 of Cisco that uses Weighted Round Robin, but I don't think that the Linksys uses this algorithm because it includes speeds of bandwidth unlike the cisco that does not work.  and if anyone can also check that this unit doesn't package base rather than load balanced session load balancing.  as much information as possible would be appreciated!

  The standard of the LRT load balancing is alternated:

  Example:

  1 TCP connection to website-online WAN1

  2 TCP connection to website2.com-online WAN2

  3 TCP connection to website2.com-online WAN1

  4 TCP connection to website1.com-online WAN2

  If you enable the feature (recommended) sticky load balancing load balancing is done on a base per session instead of the base of the connection.

  Example:

  1 TCP connection to website-online WAN1

  2 TCP connection to website2.com-online WAN2

  3 TCP connection to website2.com-online WAN2

  4 TCP connection to website1.com-online WAN1

  We want to apply the service load balancing, however recommended to oracle

  F5 BIG - IP LTM for OEM 12 c load balancing

  How much does it cost? and is there a free alternative, we can use which supported by Oracle?

  I doubt that my company will pay for the SLB.  If not buy one of these solutions, which can set up?

• Active ADF data service does not work when the load balancer compresses

  Hello
  
  I have Active Data service table in a page.
  After you enable the setting cache and turned on compression on the hardware load balancer, Active data service table refresh no more in the application.
  
  We use F5 for balancing load and data compression.
  
  Pointers?

  You can check if your F5 loadbalancer has enabled text compression.
  Disable compression of text.

• Differences between the ISCSI connections to the storage in vSphere 4.1 and 5.0.

  I'm in trouble of setting up the connections of storage in a new VSphere 5.0 test environment. In our environment VSphere 4.1, it was possible to create a virtual switch add two Broadcom NetXtreme II 5709 NIC. Set assets. IP Hash value as load balancing. (LACP Etherchannel on physical switches) This configuration uses a grain port and a single IP address. Then add our NetApp NFS storage and ISCSI Equillogic storage. In VSphere 5.0, I can't create this same configuration. I have to create separate with separate IP addresses vmkernal ports? The idea was to have redundant connections to the storage and flow of these two NETWORK cards. Possibly adding additional if necessary to the futuer NETWORK cards. Any help with this would be greatly appreciated.

  How can I work around this:

  "VMkernel network adapter must have an active link exactly and no waiting rising to be eligible for the iSCSI HBA connection."

  I can certainly say that the way which allows you to configure the iSCSI Multipathing is incorrect.

  The main idea is to let Native Multipathing Plugin to decide what network path to choose, not the vSwitch.

  At the level of the network layer, you must have 1 VMK by a physical NIC.

  This technique applies as well for vSphere 4.1 and 5.0, but with the 5.0 it is configured easier and more quickly.

  Here's a very brief consequence of steps

  1. get 2 VMK interfaces and assign an IP by each VMK.

  2. set each VMK to use only one physical NETWORK adapter

  3 GB with storage iSCSI software adapter, turn it on and bind your VMKs 2.

  4 connect to your iSCSI storage space

  5 rescan devices, create the VMFS datastore

  6. set the desired load balancing VMFS method or just set up a prior default create new VMFS

  and it is strongly recommended to read this guide - http://pubs.vmware.com/vsphere-50/topic/com.vmware.ICbase/PDF/vsphere-esxi-vcenter-server-50-storage-guide.pdf

• Oracle RAC Concept - load balancing

  Hi all
  
  I have a question about the Oracle RAC and how it balances the load.
  What I know about Oracle RAC that it load balancing between his node, so if a new session is connected to the database it will run on the node that has less load.
  If I have an application that connects to the database with little number of sessions and a few sessions are huge (huge load) implementation process while other sessions are running small processes (in terms of load).
  
  So here's an example scenario that I request a response to this one:
  If am having a two node RAC database.
  
  My application connected to this database RAC wants to run three processes P1, P2 and P3, each will have a session correlatively S1, S2 and S3
  Let's say that P1 will take 60% of database resources (memory) and P2 P3 1% and 1%.
  So my question is this a sessions load balancing or load balancing process? So in this case and at random (Managed by ORACLE RAC) S1 is connected to node 1 and it uses the resources of node 1 so the load on node 1 will be 60%, so when S2 and S3 must connect it will go to node 2 from node 1 is loaded. in this case I'll have 1 node using 60% of it's resources (because of S1 that runs P1) while node 2 uses only 2% (because of the S2 and S3 running P2 and P3).
  Is - this operation of Oracle RAC? or it S1 (60%) load balance between nodes 1 and 2?
  
  I ask this question because my application is not users, so it will connect to the database with the small number of sessions, and 1 session of them can run a huge process while the other runs of small processes.
  So in this case, how RAC takes stock of loading?
  
  Kind regards

• Least loaded node load - balancing

  Hello

  Due to dynamic service registration, a listener is always aware of all instances and dispatchers regardless 
  of their locations. Depending on the load information, a listener decides which instance and, if shared server 
  is configured, which dispatcher to send the incoming client request to. In a shared server configuration, a 
  listener selects a dispatcher in the following order:
  
  1. Least-loaded node
  2. Least-loaded instance
  3. Least-loaded dispatcher for that instance
  
  In a dedicated server configuration, a listener selects an instance in the following order:
  
  1. Least loaded node
  2. Least loaded instance

  When we talk about connection (from 9i to Oracle RAC) load balancing it are two things main considered as least loaded node & least loaded instance.
  So what factor should be considered for an average of least loaded node CUP, memory, IO, network or even the number of process running(running,sleep,...) is oracle gather information from top, utility wink to get statistician.
  And when we say least loaded node this factor are considered by oracle is that, as the number of sessions (active, inactive...) "(or killed), using component CMS." Can we say load on node is proportional to the load on the Forum... How oracle identifies and what process does it for balancing.
  
  Any docs or paper?
  
  Thank you

  Hello

  10.1 and oracle 9i

  Less loaded node means less CPU load
  Least loaded instance means less number of connections that have been made to the instance

  'Process' and "instance charge" gives an indication of the number of connections that have been made to the instance.

  "Charge of node" gives an indication of the degree of activity of the machine is. By default, 'charge of node"is the main factor in determining where to go new connections.
  For example, if you have a 2 RAC cluster and instance 1 has a load of instance node and '25' 2 has a charge of '50' node, new connections will be routed to
  instance 1.

  Changes to Oracle 10.2
  In versions of Oracle 10.2 and later, the listener uses a local value "lbscore" to determine the charge of node and instance.
  Lbscore consists of two dynamic values 'kindness' and 'delta' which are continuously updated by pmon.
  When an instance is started PMON will communicate with the listener and provide departure for goodness and the delta values...

  Listener = goodness of PMON Lbscore
  Listener Delta = Delta PMON

  To account for changes in load between PMON updated, the listener will increment the lbscore after each new incoming connection...

  Lbscore listener = listener (previous) Lbscore + earpiece Delta

  With each periodic update load by PMON the Lbscore and Delta are updated with the current data.

  Lbscore = goodness (receipt of updated PMON)
  Delta = New Delta (receipt of updated PMON)

  This note explain everything:
  * Understand and troubleshoot the Instance Load Balancing [ID 263599.1] *.
