How to load balance serving MP4 files via AMS

Hey gurus,
We have one centralized storage server that stores videos, Lets call this Server A, we have 4 more servers that we want to use to load the files from Server A to load balance and location balance the loading of files.
Servers B-E are on a private VLAN with Server A; so what we're doing now is mounting Server A on to Servers B-E and serving the files via AMS; this has proved to be quite inefficient.
For Live Streams; we use multi-point publishing to achieve this; is there a way to do this with recorded files?
Please advise!
Thanks

Here are few bits of info:
For load balancing for Analytics, that isn't officially supported yet for the UI and Administration components. It might work with sticky sessions from portal-to-analytics but that doesn't get you much. Improving the options there would be a good enhancement request.
For the collector, I think there are two important things to remember. Use broadcast mode. I've never actually seen it in unicast mode, but broadcast definitely works. Also, remember that this is all managed by Portal and Analytics - you don't use your own load balancer between Portal instances and the Analytics Collector instances.
Finally, ALUI Directory is not certified to be load balanced yet. On a separate note, ALUI Directory has a socket leak on Windows due to a bug in the version of Jrockit that ships with it. Upgrading the embedded application server for the ALUI/WCI installation to jrockit-R27.5.0-jdk1.5.0_14 will resolve it.

  • How the Load balancing happens in CPO

    Hi All,
    On what bases the process engine selects the process or request and how the load balancing happens.

    Hi!
    I am a little confused by the question (as it refers to "request"), but I am going to assume that you are asking how a High Availability Process Orchestrator environment with several servers chooses which processes running on which server.
    The answer to that question is...
    In general, processes to be executed are split equally between all servers. The only piece of data being taken into account during process instance assignment is the current load on the servers (as counted by the number of top-level processes, not counting child processes). For example, suppose that there are 3 servers in the environment, and server A is running 5 top-level processes, servers B & C are running 3 top-level processes. When new process is started (e.g. on a schedule or manually or triggered via an external event), it will be assigned to either server B or server C for execution, because servers B & C have less load. If under the same circumstances (A:5, B:3, C:3), there are 4 processes started at the same time. When the work is distributed, the total expected work 5+3+3=11 (existing work) and 4 (new work) will be distributed equally with, with servers B&C each getting 2 new processes.
    This is a general load balancing algorithms used by the servers in HA environment to decide which server runs which process instance.
    There are other factors that come into play, as some processes/activities can only run on server A or server B for technical limitations (e.g. SAP work against a particular SAP System can only be executed from one server in the environment). When those come into play, the work may end up distributed unevenly.
    Note that available memory, CPU load, or disk space on servers are not directly taken into account during load distribution.

  • Load balancing server names

    My Application is handled by three load balanced servers.I have a functionality in which first i send a request for a document printing.This request is posted in Database.Then a backend script runs and takes each requets in DB and executes and creates a file and places in server space. This works fine when i have only one server.But when i have load balanced servers user can give request for print from one server(he does know where from he is giving) and backend shell scripts can take the OPEN record from DB and execute in another server.So user is not able to find the document thought his request is processed.I have tried to know the DNS names of teh server whose are taking the print request so that i can track. But when i check with ServletRequest.getServerName() but i always get the application URL not teh specific load balance server name. I am tryong my luck with java.net.InetAddress

    Hey i could solve this problem. i have used java.net.InetAddress class and its methods to know the system name on which my code is executing.

  • How to load balance runbooks?

    Hi,
    Now I have successed to deploy an seccond Runbook Server in an test environment. But I have not fully understanding how the runbooks run on the primary vs standby. And I know that by default one Runbook Server can handle 50 runbooks, and how to scal out
    runbooks?
    How to load balance runbooks?
    How to fail over runbooks?
    /SaiTech

    you can change how many concurrent runbooks are allowed to run on a single runbook server. 50 is just a default value.
    you can assign a runbook to run on a specific runbook server (or more). this is the simplest way to load balance.
    runbooks will failover automatically. do note that the runbook will start all over, hence you need to put in safeguards in your runbook. word of adwise is to keep runbooks small and chain them together. This makes them easier to recover.

  • Load balance server

    Hello all,
    I am using Hyperion v11.1.1.1.0.
    I want to install FDM 11.1.1.
    Will it work fine with hyperion 11.1.1.1.0?
    It is written in the documentation that we need to install & configure Load Balance Server
    properly prior to installing FDM.
    How to install Load balance server and from where will I get the software for Load balance server?
    Thanks

    As Gilles said you need to make sure that the return traffic from the real server should come back to CSS.
    Your routing infrastructure should ensure that flow should be the following for both "real server in the same DC" & "Real Server in Different DC".
    1. Client Traffic should hit the VIP configured on CSS.
    2. CSS should forward the client request to the Selected Real Server.
    3. Real Server's Response should reach CSS. (It should not go to Client directly)
    4. CSS should send the response on Real Server's behalf.
    As long as the above conditions are met you are fine. Step 3 is the key and becomes could become tricky for Remote Real Servers.

  • Load Balancing Server Error

    Hi Expert's
              I am working on Netweaver BI integrated with EP. while creating JCo destinations for both  model and meta data, we have an option of selecting load balancing server and application server. the connection with application server is working fine but when come's to load balancing server it is asking for system group.
             Added to this we are working on single server. Pls let us know is system group is necessary? also let us know where to create system group?
    Regards
    Subbaraju

    Hi Ashok,
               As I already mentioned we are working on BI 7.0  We are facing problem while Configuring JCo destinations In JCo we have maintained Meta and Model Data using load balancing server and application server Now when using Tr.RSPLAN and selecting START MODELER it is routing into local host. But after logging, It is routing to standard SAP host (host=pwdfm101) instead of our local host .
    Note: Routing means opening the web Dynpro page.
    I hope this makes things clear.

    What is the proper way to load images from css in Java 8?
    Ref
    How to load images from css file in JavaFX 8 - Stack Overflow

    There is nothing special to do - you execute the statement from your program just like any other SQL statement.  The only thing to be aware of are the privilege/permission issues:
    When loading from a file on a client computer:
    READ CLIENT FILE privilege is also required for the database user.
    Read privileges are required on the directory being read from.
    The allow_read_client_file database option must be enabled.
    The read_client_file secure feature must be enabled.
    Revoking these privileges is also the only way you can prevent a user from executing the statement.

    You generally can't tell with Stream how many bytes are going to be available. You could download the whole thing into a ByteBuffer, for example, and process it from there.

    With Flash, you can't do this.

    I mean loading in a movieclip..
    Of course you can open a page to display in a browser.

    Hi
    You can use this "port-channel load-balance src-dst-ip", this will do a XOR on source & destination IP addresses and choose the interface G0/1 if the first bit of the result is 0 or the interface G0/2 if the first bit of the result is 1.
    But you can check the path used with that command: "sh etherchannel 1 port-channel"
    You can load balance with the mac-addresses too (it is the default mode I think)

  • How can I save the .mp4 files downloaded from internet to ipad memory so that I don't have to download everytime to view them again

    How can I save the .mp4 files downloaded from internet to ipad memory so that I don't have to download everytime to view them again. Also they might remove them from internet so I can't rely on the bookmark to them.

    I'm trying to send home movies to my 10 year old nephew who lives across the country. He doesn't have a computer. He has an iPod touch. His parents have computers. But I don't want everything I ever try to have him do result in "you need your parent's computer for this." It's getting really embarrassing. I have converted my family over to Apple computers but now they want to buy iPhones, iPads, and iPods even though I tell them to go Android. It took a decade to convert them away from windows now I'm trying to keep them away from these freedom limited iOS devices and they won't listen. Then it becomes my responsibility to make their iPads print to their fancy pre-airprint color laser jet printers, get home movies onto them, and countless other things. It's driving me nuts.
    I have converted these files to a format that the iOS devices will play directly off of dropbox. Now, how do I get the infernal devices to save it instead of play it?

  • How do i find a .mp4 file downloaded from email to my iphone

    How do i find a .mp4 file downloaded from my gmail email to my iphone. Unable to locate the file or maybe not sure how to go about it?

    You don't, as ringtones are a one time purchase and as such can't be redownloaded.
    If you still have them on your iTunes library, you may sinc them from there.
    If you have a backup that contains them, you may restore your phone from that backup.
    Or you can go to expresslane.apple.com and try for a re-issue. Which they do only occasionally and depending on the circumstances.

  • How do i play .mp4 files via Dreamweaver CS3??

    Hi,
    Using Flash CS3 the RTMP path to the .mp4 file is:
    rtmp://localhost/vod/mp4:sample.mp4 and it works fine to play
    .mp4's, mov's etc.....
    In Dreamweaver CS3 it wont accept any combination of paths.
    Unlike Flash CS3 which only requires the single String,
    Dreamweaver has two boxes that need to be filled in: The Server URI
    field and also the Stream Name field.
    Like FMS 2, where you don't name the streams folder in the
    url, Dreamweaver CS3 is looking for it ie the "media folder" which
    has replaced the "stream" folder.
    Where in Flash CS3 you have to use the convention
    mp4:sample.mp4, Dreammeaver will not accept anything.
    Any help here would be appreciated

    I assume from the silence that Dreamweaver CS3 has not been
    updated to handle Flash 9 player and streaming Video from FMS 3.0
    then.

  • Load Balancing, Server and / or Client ?

    Hi
    I am experiencing a problem with the connection pooling in odp.net. I have a simple test app that creates a connection, executes a query, populates an object then closes the connection. I have found that when I have client side load balancing on via the odp.net connection string property many connections are made unnecessary (sometime the actual number created reaches the max pool size but the numbers differ randomly). It appears that rather than a free connection in the pool being used more connections are being created which defeats the point of having a connection pool. I do have server side load balancing configured correctly also. Due to this finding can someone possibly answer the following questions.
    a) Do I need both server side and client side load balancing set?
    b) If I do why is the above behaviour being seen? If not could you give me a short explanation as to why not?
    Current set up is 11g (patched to 6, awaiting 7 to be applied) RAC, 2 nodes.
    Below is the C# code used while testing this. The table queried is a simple person table containing 16000 rows if data.
    OcConnection = "User Id=XXX; Password=XXX; Connection Lifetime = 60; Data Source=(DESCRIPTION=(ADDRESS_LIST=(FAILOVER=on)(LOAD_BALANCE=off)(ADDRESS=(PROTOCOL=tcp)(HOST=XXX)(PORT=1521))(ADDRESS=(PROTOCOL=tcp)(HOST=XXX)(PORT=1521)))(CONNECT_DATA=(SERVICE_NAME=MyFirstTest))); Pooling=true; HA Events = true; Load Balancing = true";
    Code:-
    Oracle.DataAccess.Client.OracleConnection con;
    con = new Oracle.DataAccess.Client.OracleConnection();
    con.ConnectionString =OcConnection;
    con.Open();
    // the command object to use for this test
    OracleCommand cmd = con.CreateCommand();
    cmd.CommandText = "select * from PERSON";
    OracleDataReader rdr = cmd.ExecuteReader();
    List<test> listTest = new List<test>();
    while (rdr.Read())

    Here are the HTTP Headers as monitored on the client side. Notice the good.txt file includes a GET as it's initial request. All works fine in this case. However, the initial request in the bad.txt is a POST. This is odd since the URL was opened using the same shortcut in both incidents and the browser was closed between each trace that was taken. I've also reviewed the shortcut with notepad to verify it does not include unwanted data such as the JSESSIONID info....etc.
    Once you have reviewed the HTTP headers, I have these questions.
    1. IIS is sending the 100 Continue messages as you mention, but why is the CSS injecting the cookie in a 100 response that is not typically processed by the client? The bad.txt file shows the client receiving two ARPT cookies because the first cookie in the 100 continue response was ignored.
    2. I know Cisco is not really in the business of troubleshooting browser behaviour. But do you know why the browser would behave differently....GET in one request and a POST in the next? We do not wish to get into modifying the browser, so I'm hoping we can provide a solution on the server side that will allow the browser to function this way if it chooses to do so. Do you think it would make sence to push the state management up a level to the cookie handed out by JRUN? This way, the cookie would not be handed back in a 100 response from IIS, and we could tell the CSS to monitor the JRUN cookie. Of course this would require we determine how to manage this cookie either by modifying to cookie to have static data for each server, or by using the right method of hashing...etc.
