Virtual IP Addresses

Hi Everyone !
My weblogic server listens on a virtual IP address. When the HttpProxyServlet proxies to another weblogic server, it doesn't make the outgoing proxy using the virtual IP address. It uses the the actual IP address assigned to the unix box and not the virtual IP address my weblogic server listens to. This has been confirmed from the firewall logs.
This is important because the firewall requires source IP and destination IP in its rules.
Is there a way to force weblogic server to use the virtual IP address for outgoing calls/requests.
Thanks,
Eddie

Thanks for your response.
I can now see the different ip addresses assigned per session id. Is there a way I can get the thin client to display the ip address as per what I'm seeing in Application
and Services Logs/Microsoft/Windows/TerminalServices-TSAppSrv-TSVIP\Admin?
We have a plugin which looks for an rds session id's unique ip address. but due to the multiple ip addresses displaying. The plugin wont work.
is there a way I can get the ipconfig to show only the newly assigned ip address.
Thank you for your response, much appreciated.

  • Changing Hyper-V host and cluster virtual IP addresses to new subnet/VLAN

    I have a 2 node Hyper-V 2012 R2 failover cluster, managed by System Center Virtual Machine Manager 2012 R2, and I would like to change the IP addresses of the hosts and the cluster, in order to move them to a new subnet and VLAN. The existing and new subnets
    are able to route to each other so all hosts will still be able to communicate throughout the parts of the process where they may be on separate subnets. There is also a dedicated cluster heartbeat network on its own subnet and VLAN that I am not altering
    in any way.
    The 2 hosts are configured with 4 nics in a team, with dedicated virtual interfaces for each of the following:
    -Live Migration
    -Cluster Heartbeating
    -Host management/general traffic (the cluster virtual IP address is also on the same subnet as these interfaces).
    It is the host management/general traffic addresses that I want to change. The interfaces were created and configured with the Add-VMNetworkAdapter, New-NetIPAddres and Set-VMNetworkAdapterVlan commands.
    Please advise if the following process is correct:
    1) Evacuate all the VMs from the first host to be changed and put it in maintenance mode.
    2) Use Set-VMNetworkAdapter to change the name of the interface (the current name refers to the VLAN it's on)
    3) Use Set-NetIPAddress to change the IP address and gateway of the interface as appropriate
    4) Use Set-VMNetworkAdapterVlan to set the VLAN ID
    5) Take the host out of maintenance mode and move all VMs off the other host
    6) Repeat above steps on the other host
    I know that I will then need to change the cluster virtual IP address, but I have no idea how to do this or where to look for that setting. Please advise!
    Cheers.

  • Windows Network Load Balancing - Virtual MAC Address

    Hi All,
    I have environment that running 2 Exchange 2010 server with CASHT and join windows network load balancing as a node.
    My question is,
    If NLB service is restart, is it virtual MAC Address for NLB will change to new virtual MAC Address?
    Thanks for response,
    Best Regards,
    Henry Stefanus

    Hi Henry Stefanus,
    The NLB work mechanism will not change whether what higher application we used and I am not very familiar with Exchange NLB architecture, may the following KB and article
    may help you.
    When you use the unicast method, all cluster hosts share an identical unicast MAC address. Network Load Balancing overwrites the original MAC address of the cluster adapter
    with the unicast MAC address that is assigned to all the cluster hosts.
    When you use the multicast method, each cluster host retains the original MAC address of the adapter. In addition to the original MAC address of the adapter, the adapter is
    assigned a multicast MAC address, which is shared by all cluster hosts. The incoming client requests are sent to all cluster hosts by using the multicast MAC address.
    Selecting the Unicast or Multicast Method of Distributing Incoming Requests

  • Programs that require a network connection won't work because there is no virtual IP address available for this session.

    Programs that require a network connection won't work because there is no virtual IP address available for this session.  Per application IP virtualization is enabled.
    There are in fact available IP address's within the dhcp scope.  Before I dig to deep into root cause.. Could the problem be RDS CAL licensing running out, or isn't that not a symptom of my error message?

    Hi,
    Thank you for posting in Windows Server Forum.
    As per my research, there is no any issue related to RDS CAL licensing. Prior to the issue which you are facing, there are some basic setting which need to configure.
    Application Compatibility – Turn on Remote Desktop IP virtualization
    Some applications require a unique IP address, which is by default logically not the case if the application is running on RD Session Host. To solve this issue, Remote Desktop IP Virtualization is introduced. With this setting you enable the IP virtualization
    feature. When enabling this setting you need to specify if the virtual IP is provided per session or per program. When using per program you need to define the executable to which an IP address should be configured. Desktop IP virtualization also needs the
    configuration of the next setting.
    Application Compatibility – Select the network adapter to be used for Remote Desktop IP Virtualization
    When you need to use Remote Desktop IP virtualization configuring this setting is mandatory. You need to specify the IP address of the Network Interface Card which should be used for this feature. Besides the IP address you need also to specify the network
    mask using the slash notation, for example 192.168.77.201/24.
    Application Compatibility – Do not use Remote Desktop Session Host server IP address when virtual IP address is not available

  • Sun cluster: virtual IP address

    Hi,
    What is the virtual IP address and how to configure it?
    For example, should it be defined in /etc/hosts? dns?
    Thank you,

    [[[s this correct to have apache HA?]]]
    Apache can be set up as a failover resource (so it is active only on one node at a time) or a scalable resource (where it would be active on multiple nodes at the same time).
    [[[Just an aside question: HAStoragePlus is NFS sharing? What is difference between NFS resource and mount resource (I saw Veritas differentiate between them)? In case I set up a shared disk, is it NFS or mount resource?]]]
    HAStoragePlus is not NFS sharing. HAStoragePlus let's you create HA storage (it's called HAStoragePlus because there was an earlier generation data service (aka Clustering Agent a-la VCS) called HAStorage). This will let you wrap a shared storage device and fail it back and forth between multiple nodes of the cluster.
    NFS sharing has to be handled using the SUNW.nfs Data service (or in other words, the NFS clustering agent) (ie only if you want to set up NFS as a HA service). Otherwise, you can use standard NFS.
    Mount resource is (i'm guessing here) any resource that can be mounted. In other words, a Filesystem.
    NFS resource is a resource that is shared out via NFS.
    [[[Also, a basic question: The shared disk should not be mounted in /etc/vfstab. Correct? It should be only present when doing format on each node. Right? It is SCS that manages the mounting of the file system? This should be up before testing apache HA…no?]]]
    That is correct. Sun Cluster will handle mounting/unmounting the filesystem and importing/deporting the disk set (in Veritas world it is called a Disk group).
    When you build your cluster resource group (aka VCS Service group), you will have to build the dependency tree (just how you would in VCS).
    1) Create empty RG
    2) Create HAStoragePlus Resource
    3) Create Logical Hostname resource
    4) Create Apache resource
    5) define dependency of Logical hostname (Virtual IP) and HAStoragePlus (filesystem) so that apache can start.
    At each stage, you can test whether the RG is working as it should before proceeding to the next level.

    ACE uses the concept of Virtual Mac Addresses , which are the addresses used for VIP addresses, NAT addresses (dynamic and static), and alias addresses These will all always use a MAC address in the following form 00.0b.fc.fe.1b.
    If you are using single ACE SM in a cat6k box, and you are seeing duplicate MAC, its normal. Cat6k Supervisor is L2 Adjacent with ACE, Any traffic received by Supervisor in VLAN 810 will be sent to ACE and then ACE will determine which VIP that packet is going to.
    Real Problem will come when you are using multiple ACE modules in Same Chassis or you are doing Chassis to Chassis ACE Redundancy. In such situation your Cat6k Switch will have duplicate MAC entries.
    To avoid this, you need to keep your Contexts in diffrent context groups in each Module i.e something like this
    ft group 5
      peer 1
      priority X
      associate-context default3
      inservice

  • Virtual ip addresses for RDS sessions

    And then when I do the same for terminal two (T2) I get 192.168.10.6

    I've tried the same via a local gpo on the RDS server without avail.

  • Virtual Host Addressing in Oracle9iAS

    Hi,
    We have Oracle9iAS 9.0.2.3 installed on Windows-2000 (SP-4) OS. Both the Instances of Oracle9iAS i.e INFRA & Mid-Tier is installed on the same machine. Our applications developed in Forms/Reports9i is deployed successfully on Mid-Tier and working OK over web with URL:: http://<Host IP>:7779/<app_name>/myprog.html
    [HTTP server running on Port 7779, <app_name> is application delployed in our OC4J Instance & myprog.html is first page which opens by above URL is kept in its relevant directory of deployed application]
    Now, i want to create a Virtual Host Address for my application that is running by HTTP Server in Mid-Tier Instance so that above URL could be avoided and intutive name can be given for the URL. I do not wish to give IP, Port etc. in URL for opening my applicaiton deployed on Mid-Tier. I wish to open like IGFL.XEXP.COM (The relevant DNS entry is already placed in Main Domain Controller machine, which will redirect to this HOST).
    I checked the documents on Metalink and followed the DocID: Note: 231351.1. I followed the steps of configuraiton without webcache setup, but this is not working properly and i am unable to trace it...Why so.?? Here, i am specifying my customized document root directory instead of AS default directory.
    Can anyone give me steps how to do it or help me identifying what i am missing. People claim that it works, but i do not hv any idea and doing it for the first time. You help is needed....Expecting your response.

    Sounds like you just want the URL to not have the port listed? If so, just change the listen port in the httpd.conf file or change it in Web Cache (if you are using Web Cache).
    Plus, you need to register a DNS entry in your DNS server to map the IP address to a name. You don't need to do anything in 9iAS for this part.

  • Configuring Virtual MAC Addresses on ASA

    Hello,
    I configure the virtual MAC address for a interface on ASA 5520, will enter the following command on the active unit:
       failover mac address Inside 0012.3456.789a 0023.4567.89ab
    The active MAC address is of the same as the Inside's burned-in MAC address of the active unit.
    Similarly, the standby MAC address is of the same as the Inside's burned-in MAC address of the standby unit.
    Do I get the effect of failover mac address command?
    Thank you for your cooperation in advance.

    Hi Bro
    That’s fine really. There’s nothing wrong if you’ve configured the active MAC address the same as the Inside's burned-in MAC address of the active unit.
    In an Active/Standby failover, the MAC addresses for the primary unit are always associated with the active IP addresses. If the secondary unit boots first and becomes active, it uses the burned-in MAC address for its interfaces. When the primary unit comes online, the secondary unit obtains the MAC addresses from the primary unit. The change can disrupt network traffic.
    You can configure virtual MAC addresses for each interface to ensure that the secondary unit uses the correct MAC addresses when it is the active unit, even if it comes online before the primary unit. If you do not specify virtual MAC addresses the failover pair uses the burned-in NIC addresses as the MAC addresses.
    P/S: If you think this comment is useful, please do rate them nicely :-)

  • RAC without virtual ip address?

    Hi,
    Our main router crashed a month ago, the network guys said that it “might!!!!” be caused by the RAC hosts flapping because the public interface NIC has two IP addresses (the main IP and the Virtual IP). They are pushing us to get rid of the Virtual IP address on the RAC nodes. Can you do that? What is the ramification of doing this?
    Thanks

    Just spoke to one of the top network specialists we have.
    He confirmed that two IP stack on a single NIC cannot cause a router to crash. He said that the crash however does not sound unusual - typically caused by malformed and mangled packets. And he said that these were almost always purposefully fully constructed with the intention being to down a router.
    The router choking on such packets are also usually also a 'known cause' by the manufacturer - and the manufacturer will have full details on root cause analysis.
    He said he would put a sniffer down to capture these malformed/mangled packets for investigation and analysis when the router crashes again.
    The culprits he mentioned - some kind of network virus, or someone "playing silly buggers" on the network.
    My network experience is out of date and not that vast - but everything I've heard from him confirms my view that your network administrators are either idiots, or trying to shift blame for some nefarious reason to your RAC.
    Either way, I would not trust anything they have to say, without them providing hard evidence.

  • Cluster Virtual IP addresses - cluvfy utility error

    Hi,
    I've just about to install Oracle 10.2.01 Clusterware on a 2 node RAC running RHEL4 AS. I'm basically following Jeffery Hunters Guide - http://www.oracle.com/technology/pub/articles/hunter_rac10gr2.html
    Each node has 2 ethernet cards - eth0 as public and eth1 as private. The hosts files contain entries for these, and a 2nd set of public IPs for use as VIPs
    I've run the cluvfy utility for pre cluster installation checks and I'm getting a VIP error. The utility finds suitable interfaces for interconnects, but fails to find suitable interfaces for VIPs.
    Has anyone any ideas what checks cluvfy is running and what might make them fail?

  • Information on the Virtual IP Address of cluster resource group

    Hi,
    I would like to know how we can find a Virtual IP address of resource group. i.e. The IP address associated to the SUNW.LogicalHostname resource of the resource group.
    Is it always present in the output of the command 'ifconfig -a'?
    What is difference between IPMP and the Virtual IP Address of the resource groups? Can these IP Addresses be common / same?
    Thanks,
    Chaitanya

    Chaitanya,
    There seems to be a little confusion in your question so let me try and explain.
    Resource groups do not necessarily have to have a logical (virtual) IP address. They will only have a logical IP address if you configure on by adding a SUNW.LogicalHostname resource to the resource group. When you create that resource, you give it the hostname of the IP address you want it to control. This host name should be in the name service, i.e. /etc/hosts, NIS, DNS, LDAP.
    When you have added such a resource to a resource group (RG), bringing the RG online will result in the logical IP address being plumbed up on one of the NICs that form the IPMP group that host the relevant subnet. So, if you have two NICs (ce0, ce1) in an IPMP group that support the 129.156.10.x/24 subnet and you added a logical IP address 129.156.10.42 to RG foo-rg, then bringing foo-rg online will result in 129.156.10.42 being plumbed in on either ce0 or ce1. ifconfig -a will then show this in the output, usually as ce0:1 or ce0:2 or ce1:3, etc.
    An IPMP group is a Solaris feature that supports IP multi-pathing. It uses either ICMP probes or link detection to determine the health of a network interface. In the event that a NIC fails, the IP addresses that are hosted on that NIC are transferred to the remaining NIC. So, if your host has an IP of 129.156.10.41 plumbed on ce0 and it fails, it will be migrated to ce1.
    That's a very short description of a much more detailed topic. Please have a look at the relevant sections in the Solaris and Solaris Cluster documentation on docs.sun.com.
    Hope that helps,
    Tim
