• ISE behind the load balancer

  I have a question about ISE profiling of the servers that are placed behind a load balancer:

  If you have an ISE environment where computers and users are be authenticated and restricted access Machine (MAR) is enabled (so that users can authenticate only on a machine already authenticated), the ISE servers up-to-date with all authentications of succesfull computer manipulated by other servers in the ISE?

  For example:

  There are 2 aircraft of ISE (ISE01 and ISE02) behind a load balancer.

  A user starts the computer and the computer authentication is managed by ISE01 (and the authentication is successful). For the moment, that the user logs on to this computer, the load balancer selects ISE02 to authenticate the user.

  ISE02 will be aware that the computer has been already properly authenticated on ISE01, so that users are able to connect? Or she refuses authentication of the user, because he thinks that the computer is not (yet) authenticated and Machine Access Restrictions is enabled?

  Kind regards

  ISE servers are aware of all authentications of succesfull computer manipulated by other servers in the ISE?

  => N°

  they are independent servers that replicate that configuration.

  If a user must always authenticate with the same ISE.

  In addition, a load balancer kills profiling since profiling requires you to cover a portion of the traffic at the ISE

• Verification of the load balancer

  Can someone suggest me, what is the best possible to check if my query selects are running on both nodes?

  The query specifies a number of active sessions on each instance.

  TMP_USER has 3 active sessions on the instance 1 and 1 session active on the instance 2. So yes, the load balancing seems to work.

  You can join gv$ session to gv$ sql by INST_ID select and sql_id to show the transaction.

• Maxum interfaces for the load balancing wan

  Hi all

  You know the interfaces maximum wan that I can use for load balancing?

  Hi Iimran,

  Lets say your sonicwall has N interfaces. You can use the interfaces wan (N-1) for load balancing

• Can someone tell me what the recommendation of Oracle is on how to best configure the load balancer?

  We are currently using the "configuration.properties" file to identify load balancing our servers, but we are curious to see if it is the recommended method to configure load balancing, or if there is a better way.

  I opened a case with Oracle support and asked the same questions - entry configuration.properties of the file servers is the only supported method used by Peoplesoft to balancing upward through 8.54.

• 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?

• Vary the size of the host and the load balancing

  I have a 4 4-host ESX cluster that is almost the maximum ability to manage virtual machines ~ 80 (and growing).  The hosts are configured with 4 to 8 cores and 32 GB of RAM each.  RAM is currently the bottleneck; Processor is not far behind.  I plan to replace one of the hosts with a much larger machine, 12 cores, 96 GB of RAM.  If a host is significantly larger than the other hosts in a cluster, DRS will still do a good job of load balancing?  I guess the DRS will place multiple virtual machines on the host to the largest.  Is there a risk of DRS. putting too many virtual machines on the largest node?

  Until the cluster is in CVS mode, or processors are compatible vmotion, you can vary the size of the resource of physical machines in the cluster.  DRS will try to balance the load, the better it can over all cluster resources.  Depending on your level of DRS aggressive, improving to a particular machine in terms of past performance is considered, so more that likely, that you will have more vm on the host of the largest.

• 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!

• Load balancing across the NETWORK interface card

  Hello

  Our ESX Server's NIC six, two for SAN, one to the dedicated Service Console and three for the virtual computer LAN traffic. I noticed one thing look in the performance tab in VC, is that all LAN traffic seems to go on one of the three the NIC and the other two are practically inactive.

  If I look at the network configuration for the vSwitch those with three cards network, grouping of NETWORK cards is set for 'road based on the original virtual port code '.

  Can anyone advise how to get a more 'democratic' usage of the three NETWORK adapter?

  
  
  As seen on http://www.eqlforums.com !

  How many virtual machines you host? With the load balancing algorithm you have selected (default), traffic is balanced to the vNIC level (i.e. all traffic from a given vNIC always through the same bear). This is the case for all, but the IP hash algorithm, which requires you to 802.3ad static port aggregation on your pSwitch. In most cases, there is no need to worry about the use of bear - if it's a GbE NETWORK card, you're probably not close to push the limits.

• 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.

• 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!

• Two shared the Application layer without load balancer

  Hi all
  
  I created the system of Application of layer two without the load balancer.
  
  EBS: 12.1.3 DB: 11.2
  
  I have two URLS:
  
  https://XYZ:8002/OA_HTML/APPSLocalLogin.jsp
  
  https://ABC:8002/OA_HTML/APPSLocalLogin.jsp
  
  I run the auctoconfig on the last node abc. When I try to access the https://xyz:8002/OA_HTML/APPSLocalLogin.jsp, it automatically redirects to https://abc:8002/OA_HTML/APPSLocalLogin.jsp
  
  If autoconfig on xyz last execution, https://abc:8002/OA_HTML/APPSLocalLogin.jsp URL automatically redirects to https://xyz:8002/OA_HTML/APPSLocalLogin.jsp.
  
  I know in 11i is the behavior, but according to my understanding in R12 this shouldn't ' e be the case because another application works very well.

• The console to load balancing proxy

  Hi people,

  I have set up 2 servers of vCloud Director for redundancy:

  Server 1:

  http address: vcd1.example.com

  Console proxy address: vcdcon1.example.com

  Server 2:

  http address: vcd2.example.com

  Console proxy address vcdcon2.example.com

  I've set up a public URL through a load balancer: vcd.example.com. It works perfectly - I can connect to the public URL on the load balancers and functions of vCD correctly.

  It is:

  https://vcd.example.com load balanced back end vCD servers vcd1.example.com and vcd2.example.com.

  Now I try to get the proxy to the console through the load balancers and have not been able to get this working.

  First, I checked the remote console works when connecting to the address consoleproxy on the servers of vCD, for example vcdcon1.example.com and vcdcon2.example.com. The console connects very well and I can connect to the virtual machine.

  I set up one address public consoleproxy on the load balancers, for example https://vcdcon.example.com that load balances at vcdcon1.example.com and vcdcon2.example.com.

  When the remote to a computer virtual console is launched, I get the following error:

  Unable to connect to the MKS: Timeout during an attempt to read.

  I tried this on a Juniper DX load balancer and a device of Zeus Traffic Manager and get the same results. On Zeus, I can see the last HTTP request sent from my PC before the above error is visible:

  CONNECT 10.10.10.100:902 HTTP/1.1

  10.10.10.100 is the public proxy IP console, i.e. vcdcon.example.com.

  I use self-signed certificates free for the public and back end https.

  Someone at - it work for vCD consoleproxy addresses of load balancing?

• Load balancer and the consolidation of NETWORK cards

  Hello

  We recently had to our file VMware Server after a bit nasty failure of his original material.  Since we moved, it mostly worked OK, but we don't get the occational network shares paw when large files are thrown on.

  ESXi host, sure it works use 5Gbit ethernet adapters on the same Virtual Switch.  Looking at the traffic it would seem that all traffic flows in just a single NETWORK adapter and it is not much at all through the others.  Is something that I need to set it up so that it can better load balance between network cards?  Or is it a document anywhere who recommended settings for multiple network cards?

  I found a vDS topic but we have not undertaken more liciencing on most of our servers.

  We run VSphere 4.1 via the Vcentre server.

  Thanks for the help.

  What you say makes a little more sense on what I see.  There is very little traffic flowing through other NETWORK cards, but is perhaps because there isn't any real traffic goes to them.  I thought that VMware may use multiple NICs, if it was required that is why I thought I'd see more data on the other.

  Curiosity is anyway that I can combine NICs for more flow using VMware?

  The load balancing, you can achieve with VMware is not a "real" load balancing, this is more a static distribution of traffic in accordance with the policy, you have chosen.

  You use means that according to the virtual switch port ID the vNIC to the host is connected to a specific bear is chosen. This unique vNIC traffic will use this bear as long as this bear does not fail. In this case the guests more with vNIC, you have the better are used Teddy.

  Other policies can be better for other scenarios. For example, 'Hash IP' uses the source IP address and target to choose a teddy bear. It is a good policy for a server with a vNIC single file and many different communication partners. The 'Source Port' policy route all traffic through a teddy bear so that 'Hash IP' policy would use many Teddy as not what ID port is used, but the communications partners. And a file server must have many of them, more than it has of vNIC.
