• Single point of failure/Cluster/high availability on Essbase 11.1.2

  Hello

  The project I am currently working has only one Version of Unix 11.1.2 Essbase server that's threat as a single Point of failure. Management thinking to upgrade the Essbase to superior verion 11.1.2.1 to achieve clustering & high availability and to overcome the situation of single Point of failure by having just a server unique essbase.

  My concerns here are;

  Note: Essbase in this project is used to generate reports only, write back data is not allowed.

  (1) not supported of the Essbase Version 11.1.2 Cluster / HA / failover to the other node?

  (2) if it is Yes, can you please share the link to the documentation for this version 11.1.2.

  There are other components of Hyperion as HFM, FDM used the same version in this project. If the failover is not supported in the version of Essbase 11.1.2 we need upgrade other components as well as the Essbase or just Essbase upgrade upgrade to version 11.1.2.x is sufficient.

  Please share your valuable thoughts on that.

  Thanking in advance for your ideas.

  Kind regards

  UB.

  
  

  Found the reason why Essbase Cluster does not work when implemented with failover / high availability when Essbase Analytics link (EAL) used in the project. Due to these facts, we have stopped application Essbase Cluster and the Essbase in my project remains SPOF (Single Point of Failure).

  Not sure if Oracle Corp. comes with EAL product improvements that can take over for Essbase Failover.

  "

  1. Essbase Analytics link (EAL release 11.1.1.4) does not support high availability facilities. This means that EAL cannot connect to a cluster of Essbase, always happens only connections to a server regular Essbase through the Regional service console. Although we can define availability high for Essbase, EAL will use a single Essbase server. If it breaks down another Essbase server is used, we must manually redefine the EAL bridges on the new Essbase server and re-create the database Essbase. It is not considered high availability in this case.
  2. There is no technical mechanism to link point to a Cluster Essbase-Essbase analytics. EAL is supported only to connect to a single named Essbase Server.
  3. Transparent partitions can support when configured Essbase as component availability high when EAL is used. EAL bridges in the active project uses Transparent partition.

  "

  Please feel free to correct me if this interpretation is wrong.

  Thank you

• VSphere hosts high availability 2

  Hi all

  I am trying to achieve the following by using the essential plus the package. I had 2 identical machines with 2 TB of storage. The two are running ESXI and I want to configure high availability and load the pendulum. From what I've read on for them is that vmware needs shared storage so kind of san if I want to use high availability. But I don't have this machine, what I want to achieve is the following: Vmware reflects the discs on both machines (network raid 1) and if a hardware failure occurred on one of them, the other machine will start all the vm remaining. In the same way vmware should do load balancing. From what I've read on the internet vmware had VSA, but this has been discontinued. VSAN is not an option, because I don't have 3 machines. One possible option would be for example starwind but I would have preferred an option of vmware itself.

  So in short it is a way to configure high availability and load with 2 hosts balancing and not shared storage? Preferably without third party software.

  Kind regards

  Technically, you can use DRBD and Linux (or FreeBSD and POLE if you're on the dark side of the Moon) to create a device block tolerant replication between a pair of virtual machines running on a hypervisor nodes. Throw in

  failover NFSv4 point mounting on top and you have a nice VMware VM data store. Tons of a defined software storage vendors have exactly this ideology within their virtual storage devices if you do not go to the difference

  However as StarWind Virtual SAN is FREE for the installation of 2 knots in the scenario of VMware (Hyper-V licensing is different if you care) and can be run on a free Hyper-V Server (no need to pay for licenses of Windows), you CAN end up with a faster

  back from road StarWind. Depends on what you want from a set of functionality (iSCSI? NFS? SMB3? Online dedupe? Cache?) and what forum do you prefer for public support to ask questions

  --

  Thank you for your response. I thought that since preparations are exactly the same secondary machine would be able to easily start the vm of lost. For synchronization, I thought it would be something like drbd, when unable to connect with the other secondary hosts will become primary. This works in the case of a hardware failure, and network failure half a brain will take place that must be resolved manually. I play with it replicaton and reconsider the starwind software.

• It is possible and effective: high availability (failover) on 2 guests with local storage?

  Hello

  I have a discussion on the implementation of ha (failover) with 2 guests with local storage.

  My advice is to go with a shared storage. But there is another view, use the cluster failover MS with local storage service to save on the shared storage hardware.

  2 "mirorred" on each host machines. Is it feasible at all?

  The HughesNet: have 2 virtual machines (SQL server and server applications in a highly available environment). The workload of the machines will be raised to 2 very powerful servers that are supposed to be buying.

  1. Please briefly explain a feature of local storage to provide HA.

  2. I got to cluster in the virtual environment, not so I guess that the shared storage is used only in the virtual environment.

  Thank you.

  Michael.

  There is software that can replicate a running, physical or virtual machine to another accessible location on the network. This could be as simple that between two close hosted ESXi of VMS or high-speed WAN. Take a look at things like neverfail, doubletake others.  The costs would probably be a bit prohibitive in a smaller environment. It might be possible and maybe even practice to use a virtual storage device having a failover replication. Use of storage on each host and allows to provide the data store. Open-e

  The Microsoft Clustering solution needs a shared storage.

• High availability of components in the design of vWorkspace tips

  Hi all

  Would ask you some advice regarding the design of vWorkspace components highly available. Suppose that vWorkspace components will be deployed in vSphere or hypervisors managed SCVMM hence HA is in place, if the failure of a host. In this situation, if we still need components redundant (n + 1 VMS) vWorkspace?

  On the other note, I understand that we can add a couple of broker for vWorkspace in vWorkspace Management Console connections and based on KB 99163 it would just work. I'm not sure how the traffic would be when an application is web access? As in, I guess that the connection broker news would be 'defined' at the request of the web call to the broker for connections. Or this is done automatically? Access Web would choose randomly from the broker for connections to go?

  Thanks for any advice in advance

  Kind regards

  Cyril

  Hi Cyril,.

  Big questions. As with any IT architecture in layers, you must plan HA and redundancy at all points of failure required by your environment or level of Service (SLA) agreements. For vWorkspace, the center of his universe is SQL and you must plan accordingly the failure and recovery. In some environments, full backup can meet the requirement of HA. In others, full SQL Cluster, Mirroring, replication, or Always-On configurations may be required. With our broker, we recommend N + 1 deployment in most scenarios HA. When you move peripheral components or enabling, you must evaluate each component and needs its impact of failure as well as its valuation to determine the appropriate AP.

  Load balancing between several brokers is done automatically by logic in the client connectors. In the case of Web access, when you configure the site Web Access in the Management Console, it includes broker list in the Web access configuration xml file. As client connectors, Web Access includes balancing logic that distributes the client load on brokers available automatically.

  If you have any questions about specific components and requirements of HA or architecture, please add them in the discussions.

• Windows 7 Home Premium with invalid Code of Activation in the virtual environment

  I have a PC with Windows 7 Home Premium, I could get the Product Code of Magic Jelly Bean KeyFinder.  I created a Virtualbox Win7 environment to test the code for what should I have to rebuild my computer I have everything properly.  Although I enter the code correctly when I try to activate it says that is not valid.  Is it because I'm under a system with it already running with the same product code that it does not work properly? Or something else?

  If your intention is to rebuild the desktop, why would need to test the activation code to see if it works, when it is currently working on the host itself? I can understand the Windows 7 Home Premium assessment in the virtual environment, but the idea of the code itself, no.

  If its already active in the host, then that means it works.

  If Home Premium from Windows 7 is pre-installed on the host itself, the code that you use cannot be used to activate Windows 7 elsewhere.

  New computers coming often pre-installed with Windows 7 have what is called a recovery partition. This is used to reinstall an operating system in the case of a system failure. To access it, you need to start when you start your computer by pressing a function key. This can be either F1, F2, F9, F10, F11, F12 key DEL or tab. See the manual that came with your PC for instructions on how to reinstall Windows.

  This is how the recovery partition is accessible to most popular brands...

  For Dell, press F8 on the keyboard until the Advanced Boot Options menu appears on the screen.

  For HP, press F11 directly after switching on the device

  For LG, press F11 directly after switching on the device

  For Toshiba, press and hold "0" BEFORE and during the power upward

  For Acer, press and hold ALT + F10, as soon as you see the logo

  For Asus, press F9, as soon as you see the Asus logo.

  For Samsung, press F4 to the power upward...

  For Fujitsu, press the F8 key directly after the power

  Advent, restart your computer. Then, press F10 repeatedly until the message "Starting system recovery"

  Sony VAIO, reboot and press "F8" or "F10" repeatedly until the screen "Advanced Boot Options".

  If it is a retail license and you need to reactivate Windows 7 Home Premium if you reinstall from scratch, you can still use phone activation:

  How to activate Windows 7 manually (activate by phone)
   
  1) click Start and in the search for box type: slui.exe 4
   
  (2) press the ENTER"" key.
   
  (3) select your "country" in the list.
   
  (4) choose the option "activate phone".
   
  (5) stay on the phone (do not select/press all options) and wait for a person to help you with the activation.
   
  (6) explain your problem clearly to the support person.

• Deployment of high availability of the IPCC 4.5

  In a future HD architecture implementation, the voice service will provide CallManager 5.0, that will integrate with 4.5 of the IPCC. 4.5 (required with 5.0 CM) IPCC does implement a high availability. How can we ensure that technical support continues to operate if the IPCC goes down? One possibility might be to configure CM such that if the IPCC goes down, all the number of help desk calls are automatically and immediately headed to a group (which includes all extensions help desk). This redirection can be configured in CM? Is there a better option?

  Thanks in advance,

  SB

  This is your best bet. On the road Points for your call center just put the call before busy, no answer and failure to the fighter pilot. Thus, when the IPCC Express Server is down it will sent to your fighter pilot.

  Please evaluate the useful messages.

• Two WLC 5508 anchor high availability

  Hello.

  It is possible use 2 WLC 5508 EN HOW to ANCHOR in an active scenario?.

  For example, if a WLC down the service, another Dungeon provide service to customers of anchor?

  At the moment we have just a WLC 5508 anchor mode. What do I have to configure high availability of the ANCHOR.

  Thank you very much!!!

  You have redundant WLC as anchor points, but if an anchor fails, the user must reconnect.

  There is a feature on the WLC HA, but it is mainly for foreigners redundancy WLC anchor no redundancy. With guest several anchors overseas WLC balance the load between the two. You will not be able to put a primary or backup.

• ID in a virtualized environment

  Can someone develop an IDS solution for a virtualized environment?

  I have ESX/ESXi - highly virtualized blade servers.  IM using the blade passes under chassis e/s - no pass-through.

  The requirement is to run a service IDS such as VM-on-VM traffic is controlled. The traffic flow can be between two virtual machines on the same blade, 2 virtual machines on two separate blades in the same chassis, or two separate virtual machines on two hunts...

  In this case, I see 3 streams of traffic off of the bat...

  blade even: vm-on-vm traffic is enabled by a hypervisor type switch (vDS 1000v or vmware).

  different blades in the same chassis: vm-on-vm traffic will leave blade and can be set by hardware chassis (blade chassis I/O) switch.

  different chassis: vm-on-vm traffic will have to go to ToR (maybe same end of line).

  NOTE: If the VMs are on different VLANS, traffic will always be at the end-of-line/agg switches (the limit of L3/L2).

  So, given all of these possible flows, what is the best way to go about deploying IDS service? Implementation? Virtual or physical? etc...

  Thank you!

  You're right, dragging the flow of vm virtual machine out of the box for the inspection of the IPS and stuffing then reconnect will be a bottleneck of bandwidth. I doubt that it would cost you more CPU to move these pieces sttings to launch an IPS sensor inside the box (ala Sourcefire).

  To minimize the bandwidth bottleneck, you can add Ethernet interfaces to your ESXi server and even to group several togther if you need more bandwidth, a single pair can offer.

• NAC Manager high availability peer CAM DEAD

  Hello

  I have two managers of the NAC with high availability and I used both interface eth1 of sides as a link Heartbit.

  I did following steps for high availability.

  (1) synchronize the time between two cams.

  (2) generate a temporary SSL certificate in CAMs and import-export procedure made in the other.

  (3) make a CAM as a primary and the other as secondary.

  But after all this made configuration I can see the State in surveillance > reports-primary CAM is in place in both servers and redundant CAM is down.

  Also on the failover tab, I can see - Local CAM - OK [Active] and counterpart CAM:-DEAD.

  I have attached some screenshots so that you can find the same.

  Your help will be very appreciated.

  Thank you

• Fabric interconnecting Cisco high availability

  Hi Experts,

  I would like to know,

  (1) what does fabric adapter interconnection cluster (L1, L2) ports are using high availability?

  (2) can form us able to interconnect fabric and fabric interconnection interconnection 6100 6200 to a cluster? If ok means how they exchange of history since the two are completely different material. ?

  Thanks in advance,

  Jako Raj

  Hello

  (1) L1 and L2 ports are used for the purpose of managing only basically to synchronize data management, triggering a possible failover.

  (2) different hardware platforms are supported in the same cluster only in a process of upgrading equipment. Actually what really happens in this meanwhile is the copy of the configuration and the new FI is promoted as primary. Although he works as a group, he is an active-standby cluster, where a single FI acts as principal.

• ASA 5520 high availability

  I have two ASA 5520 s.  We have an ID card and we didn't. This makes the wizard high availability fail.  Can I manually configure high availability.  I don't really need two ASA-SSM-20 s.  I just want to have an ASA in standby mode.  Is this possible.  Does anyone have a configuration similar to that?

  The hardware should match. If you want to switch then remove the Sam from the primary or add one in high school.

• High availability with two 5508 WLAN controllers?

  Hi all

  We are considerung to implement a new wireless solution based on Cisco WLC 5508 and 1262N Access Points. We intend to buy about 30 access points and have two options: either buy a WLC 5508-50 or, for redundancy to, two controllers 5508-25.

  Is it possible to configure two WLC 5508 as a high availability solution, so that all access points are distributed on the two WLCs and during breaks WLC one another case manages all the APs?

  If we have 30 access points, and one of the two WLC 5508-25 breaks of course that not all access to 30 but only 25 points can be managed by one remaining. Is there some sort of control to choose the access points must be managed and which do not?

  How does such a configuration looks like in general, is the implementation of an installation of two controller quite complex or simple?

  Thank you!

  Michael

  Hi Michael,

  Do not forget that the 5508 works with a system of licensing. The hardware can support up to 500 APs, but it depends on the license that you put in.

  I think 2 5508 with 25 APs license will be more expensive than a 5508 with 50 APs license.

  If you have 2 WLCs, the best is NOT to spread access between the WLCs points. In doing so, you increase the complexity of homelessness (WLCs have to discount customers to each other all the time). If your point was to gain speed, it really doesn't matter as the 5508 can have up to 8 Gbit/s of uplink speed and has the ability of UC to treat 50 APs with no problems at all. So I find it best to have all the access points on 1 WLC, then if something goes wrong, all the APs migrate anyway for the other WLC.

  If you want 50 APs at a 25-degree WLC failover, you can select who will join Yes. The APs have a priority system, so you assign priorities. If the WLC sees it's full capacity but higher priority APs are trying to join, it will kick down-prio APs for the high prio allow to connect.

  WLCs is not exactly "HA." It's just that if you have 2 WLCs work together (as if you had 700 APs and needed to put 2 WLCs) and delivered to customers. Or all APs sat on a WLC and when it breaks down, they join the other available controller.

  The only thing to do is to put each WLC in the same group of mobility so that they know.
