How do you cluster Maverics server?

How do you cluster Maverics server?  I have two Mac Minis running Mavericks server that I would like to cluster (mirror) together preferably as load balanced but failover would be the next best thing.  I am not actually using the services of server, but am hosting a streaming application.
Any ideas?

In terms of general Mac server 'clustering' Apple used to provide capabilities to do this but sadly killed off all their options in this area some time ago.
In your case even if Apple still provided those capabilities they would not apply as any streaming application would need to have been written to provide its own clustering capabilities.
The nearest option you can get to realisitically with Mac servers is to use DNS load-balancing where a load-balancer will 'share' the load between two or more servers and also test a server is live before sending a request to it. The servers need to have some method of having the same data which might mean using a SAN to store the data and Macs can access a SAN as MrHoffman mentioned. However none of Apple's own server services would really benefit from this.
A hypothetical example that could be achieved would be to have two Mac servers running Apple Software Update Server, you would not and cannot point client Macs to both but you could point client Macs to a DNS load-balancer which would allocate requests to one of the Mac servers. In this case the two Mac SUS servers might indepenently download updates or you might use the same 'folder' on a SAN or you might run some other sync command between the two. In my own case I actually setup two SUS servers in VMware virtual machines using Linux and had them each store their own copies but sync their folders, I had one run at 12am and one at 12pm so updates got downloaded twice a day. The DNS load-balancer then forwarded requests to either of them. (I used Reposado to act as the SUS software.)

  • How do you configure the server in this situation?????????????

    Hi,
    We have Oracle 10.2 and Windows 2003.
    We have Oracle on Cluster (with Windows software).
    When the System are without cluster all it’s OK!!!!!!
    We have 2 Resources Cluster Group: Oracle and Applications.
    We have Oracle in Oracle cluster group.
    We have “W” Drive and a ftp program in Application cluster group.
    We have C drive in both nodes. We have installed Oracle in both nodes but we have “W” drive only associate to the Active Node because is a Cluster resource (Application cluster group).
    All days we receive text files by ftp and we put it on W Drive. This text files are readen with external tables in Oracle.
    We have a problem when oracle fails and it goes to the another node (for ex. node2) because the external tables fail because the files are on Node1 on W Drive. If we move manually Applications cluster resource to Node2 then all it is OK.
    We think to put UNC pathes instead of “W” but it’s not possible (Metalink: Note:290703.1)
    How do you configure the server in this situation?????????????
    Thanks!

    We run a similar configurations and i doubt you have a chance other then reconfigure your setup. The way we do it is to have an ftp client in our database group and periodically transfer the files a second time (not elegant but it's working).
    If that's not an option you might be able to use unc names in your ftp server and set the ftp root to a directory hosted on a disk which is part of the database group.
    Or move to unix (that's what we do now). Than you don't have to bounce your server once in a month to apply security patches...

  • How  can you load local server urls on application start?

    Background:
    I've been searching for close to two days for an answer to this question, it's full of gotchas and I can't quite get it figured out.
    I have an application which contains several web services. These services load up listeners when the services are invoked which makes them available for input. The user has the option of disabling automatic load of these services and invoking them manually by typing in the local url and starting the app. The can allow the autoload which uses a the or allowing the auto load to start. Currently the local url is hardcoded in a property file and this is how the services knows the local endpoint to envoke when it autostarts.
    <servlet id="AutoStart_01">
    <servlet-name>autoStart</servlet-name>
    <servlet-class>com.loadmy.StartupClass.Here</servlet-class>
    <load-on-startup>1</load-on-startup>
    </servlet>
    This works all fine and well until it's deployed onto a machine that runs a local weblogic cluster that has more than one jvm (and multiple ports) loading the application up.
    Problem
    The question is, how can you get the applicaton to recoginize the local url for the jvm that is running which can be on different ports? Here's what I've tried
    A - Using Inet.Address - This doesn't let you know what port your application is on
    B - Using the load servlet on start up ( Only the init() function is called and the request object hasn't been created and the request object is what contains ther protocol, server and port information)
    C - Loading a jsp page (READ... purposefully loading a jsp page) on application start. The thought here is that this contains a request object, but unfortunately on this doesn't work in my servlet container (currently tomcat 6 but the application is for a web logic machine)
    D - I thought about possibly using System.properties() but no luck there
    I'm at witts end on this one and I know there is something that can recoginze the local servlet container and extract the url and port from it.
    Any suggestions would be great.

  • How do you add DNS server to a VNET?

    I'm trying to create a VM to serve as a DNS server for my VNET, but when I attempt to create a new VM, I'm forced to select one of the subnets I created, which would render it inaccessible from all other subnets. How are you supposed to create a VM in
    an address space that would be accessible to all subnets in a VNET?

    Hi,
    You could try Reserving the internal IP address of the DNS server in your VNET and register it as a DNS server.
    To Register DNS Server, in the management portal Click on New -> Network Services -> Virtual Network -> Register DNS Server, as shown below.
    Then you should be able to assign it to the VNET.
    Additionally to reserve an IP Address for a VM you could refer: http://msdn.microsoft.com/en-us/library/azure/dn630228.aspx
    If you want to set a static IP address for a VM that you previously created, you can do so by using the following cmdlets:
    Get-AzureVM -ServiceName “Servicename” -Name “Vmname”  | Set-AzureSubnet –SubnetNames “Subnet” | Set-AzureStaticVNetIP -IPAddress 192.168.44.4| Update-AzureVM

  • How do you configure Enterprise Server to allow WiFi retrieval of email when in WiFi Area

    We have an Enterprise Server and WiFi in offices and homes and lots of free WiFi on our travels.  How do you configure the phones/enterprise server to allow this?  I cant see any easy option??

    Llessur999 wrote:
    That is a reasonable approach. Without changing network configuration, I don't see an alternative. A few considerations:
    Based on your experience, will the length of time to detect unreachability (a network timeout?) cause a usability issue?
    Must you support a scenario where a user transitions LAN-to-WAN or WAN-to-LAN while using the app?
    If this is used by a wide audience, will configuring the primary/fallback be straightforward?
    I don't think there's a usability issue.
    Yes. The app is designed for a brick/mortor location that essentially wants to drive the user to the location. The user has to ability to interact with specific hardware components at the location via server/port communications - some of which they can do while they are remote. While they are on location, they need to retain that ability to interact with local equipment even more. Users could be asked to not go on the location wifi of course but that just seems silly and an overall bad user experience.
    The primary/fallback configuration should all be done within code (no user interaction). For example the WAN IP will always be X.X.X.X (be it Public IP or dyndns - makes no difference), while the LAN configuration will always know that the lan server it needs to communicate will always be at a specific LAN IP (192.168.x.x).
    It would be  godsend to have some sort of API call (or class) that can accept a call to CFStreamCreatePairWithSocketToHost to a specific IP and on seeing that it's unreachable automatically try the secondary IP before returning a failure on the stream.

  • How would you make a server on Visual Studio?

    Why not use something like SQL or MySql? You would simply install the database software on your VM or server, then you configure your server's endpoints, firewall/router's ports, and you should be good to access it from any Client-Capable software.

    Turn Email services on in Server app.
    Configure Email service specifics in Server Admin.

  • How do you setup a server to use multiple DNS servers that are not connect to each other?

    Is there a way to setup a server that connects to two different domains to use the proper DNS server for name resolution?
    Let say there are two DCs: serverA.subdomaina.domain.com and serverB.subdoamainb.domain.com.  The domains are independent and not connected.  Now you need a common server that is connected to both and need to resolve names from both
    domains.
    Is this possible?
    I have setup a server in a workgroup.  One NIC has the subdomaina.domain.com connection specific suffix and the other nic has the subdomainb.domain.com.  Each NIC has the DNS server listed for the domain it is connected to.
    This configuration will resolve FQDNs of one domain but not the other.  This I believe is due to the fact the server only querys one DNS server and doesn't try the other DNS server.
    Is there any way to make the server try another DNS server, if the first one doesn't have the entry?

    Hi,
    Thank you for posting in Windows Server Forum.
    Here adding to the words of “Tim”, a forwarder is a DNS server on a network used to forward DNS queries for external DNS names to DNS servers outside of that network. You can also forward queries according to specific domain names using conditional forwarders.
    A DNS server on a network is designated as a forwarder by having the other DNS servers in the network forward the queries they cannot resolve locally to that DNS server. You can refer information regarding forwarders and how to configure from beneath link.

  • Inability to RESUME download in ffox - how can you see if server supports resume e.g. any of the filehosts

    Hi Cor-el
    I found Opera. Opera browser does not compare to firefox greatness. Nor does their support help forums.
    But Opera does have RESUME button on their download window.
    The trick with opera, is to open the download manager in a new window, and make it look like Firefox great add-on DownloadManager Tweak.
    then it looks the same, so you know what your doing
    AND it has a download / RESUME button
    fyi:
    > I tested Opera Download on all the failed ones (trying the tricky rename workaround) '''Opera RESUMED in all 9 test cases.'''
    > and where i could not get firefox to resume, not once in all 9 test cases.
    so my conclusion is the workaround is not very good. And it had nothing to do with the server i was downloaiding from (in these 9 test cases)
    perhaps..... in a future version: - firefox can also have the wonderful resume button, and the add-on Download Manager TWEAK, can also have the RESUME download button.

  • How do you update your server when its not connected to the internet?

    This is actually a Windows Update question.
    My OS is Windows Server 2008 Standard, Service Pack 2.  It is a stand alone system.
    Crazy, I know, but I want to keep my server updated with the latest security patches, Software Patches, etc., even though it will soon not be connected to the internet.  Right now it is and I am making certain it's completely updated prior to removing
    its connection.
    How would I do that?  I realize that I will have to do what "Window's Update" does, but do it manually.
    Please help! I'm new to servers and I will need this to be very much a step by step. Don't be surprised at to what I don't know at this point.  I am learning though!
    Thanks in advance.  Any and all help will be very much appreciated.

    Hi TimothyJohn,
    You either,
    - Setup a disconnected Wsus in the same LAN than your server. See Wsus documentation to see how to do that and how to update a disconnected Wsus.
    - Use a third party tool like "Wsus Offline" :

  • TA27369 how do you see the server monitor application

    I am trying to troubleshoot on an Xserve.  Cannot see the drive and triangle light is blinking.  My search tells me to view the server monitor application.  What is this and where can I find it if I am unable to see the hard drives? 

    Is the XServe booted? If not then Server Monitor isn't going to help you much. All it can do is give you environmental status of your server (power supply, memory, temperature, etc.). It can't diagnose a failed disk or restore a failed system.
    That said, if you want to run it, you can run it from any other system on your network. The Server Admin tools should have been included with your server disks, or you can download them from Apple.

  • How do you allow SQL Server 2014 Express for remote connection and in firewall?

    I'm sorry if this was answered here before.
    I installed SQL Server 2014 Express and it is working perfectly. I want my server to be accessed through LAN. It is a named instance.
    I searched the internet and here's what i did:
    1. Through the SQL Configuration manager, I enabled all the Protocols of my Instance (TCP/IP, Named Pipes and Shared Memory). I changed in the IP Addresses the "IP ALL" TCP Dynamic Ports to 1434.
    2. In the Firewall I made an Inbound Rule to allow the Program (%ProgramFiles% (x86)\Microsoft SQL Server\MSSQL12.MyInstance\MSSQL\Binn\sqlservr.exe)
    3. I also made 2 Inbound Rules to allow (TCP/IP Port 1433) and (UDP Port 1434).
    4. Restarted my instance. SQL Server Browser and  SQL Server Reporting Services are also running.
    5. No Luck I cant still access the server using a different computer in the network.
    Please help.

    Hello,
    In Express Edition by default remote connections are disabled, you have to enable it first:
    Configure the remote access Server Configuration Option
    It's always a two way communication, so you have to create also outbound rules, not only inbound, and this on server as well as on client side; see
    Configure a Windows Firewall for Database Engine Access
