50000 concurrent connection

Do you know if weblogic application server can handle 50K concurrent connection? I have to make the decision if it is possible to use weblogic application server to do. If so, how many servers do i need (just an estimation is ok).

We are in production with a similar configuration (as of Feb 1).
We have two outstanding issues
1. Multicast DOES NOT WORK when dual NICs used/enabled
2. Testing using as few as 25 users (via webload, RSW and Loadrunner) causes
failures and timeouts.
The same test on a single server (cluster of 1) works fine!

  • Max concurrent connections

    Coming back to a topic that was posted a few months ago with
    an
    additional question:

    My question:
    While Flash doesn't enforce a limit, do any/all browsers
    enforce
    limits? If I wanted to load up 50, 100, 200 movies at once,
    where if
    anywhere would I be limited?
    Also, it seems that, in a test program loading a bunch of
    images from a server concurrently, I am not able to get more than
    two at once. Is this purely a server issue?

    Hi,
    I imagine it does.
    Also I guess if we are talking about just some random UDP traffic it would also mean that the default timeout for a connection would be 2min. The most usual UDP traffic would probably be DNS querys. In those cases I presume though that the UDP connections dont stay on firewall for long as long as the firewall sees the DNS reply.
    But as I said if we are talking about some random UDP traffic that is allowed through the firewall I would guess it stays in the connection table of the firewall for a couple of minutes. So you might be looking at 1000 concurrent connections or even more?
    I have once witnessed a single server sending so much UDP traffic that it reached the connection limit of an ASA5540 which is 400 000 concurrent connections.

  • Max Concurrent connections supported by UTL_HTTP

    Hi,
    Can anyone help me out to find how many concurrent connections can UTL_HTTP.REQUEST_PIECES support. Is there any parameter that governs max no.of connections? If so, pls post the parameter name.

    Assaf:  as always, thanks so much for the info!
    When you say double-sided, do you mean a memory stick which has chips on both sides; as in 8 chips on each side?
    I bought the Kingston memory one stick of 128MB PC100/PC133 which has chips on one side.  I also bought the 256MB PC100/PC133 which has chips on both sides.
    I currently have both these memory sticks in the MS 6119 and they appear to be working well.  I am running Prime95 torture test just to make sure everything is working as it should be.
    Currently I have the following memory in the MS 6119:
    Bank 0 - the original PC100 128MB stick which has 8 chips on each side.
    Bank 1 - the Kingston (KVR133Q/128R) PC100/PC133 128MB with 8 chips on one side.
    Bank 2 - the kingston (KVR 133Q/256R) PC100/PC133 256MB with 8 chips on both sides.
    The total is, of course is 512MB - and appears to be working just fine.  Windows LOVES RAM  :D

  • Limit number of concurrent connection

    is there a way for me to limit the number of concurrent
    connections to the media server. my upload bandwitdh is about a meg
    so having too many connections just kills the whole thing. i would
    like to put a limit at 5 connections. is there a way to do
    this?

    well i am only using flash media server to displaying videos
    and just that. the reason i went with media server vs. progressive
    was fullscreen method. since flash doesn't natively support
    fullscreen you have to open another browser in fullscreen with
    javascript. the problem with that is it start loading from
    beginning so i decided to go server that way it only has to buffer
    and get to the same point without having to load the whole video up
    to that point. Now i want to limit number people that can be
    watching the video. if i get more that 5 connection the whole thing
    slows down. i am not too familiar with server based connections so
    i don't know how to limit the number concurrent connections.

    Please let me know the answer

    This is very true, and often overlooked. What are you using in your
    application? I'm working on a project that is using EJBs, JSP, servlets, XML
    and XSL and very, very dynamic content.
    The xsl transforms alone were probably our biggest performance hit. We've
    since moved them to an external servlet engine (Caucho's Resin) to take some
    of the burden off of our WL servers, and performance, and especially
    scalability, have increased immensely.
    How dynamic is your application? How many queries are there going to be per
    served page? What kind of transform/building of each page is necessary?
    These are all factors that are going to impact your speed and scalability
    long before 50k users hit your site.
    Thanks,

    BEA has people that can help you estimate the amount of hardware required.However, any estimate is very dependent on the application. Personally, I
    recommend that you (with or without help from BEA) do a little stress
    testing of the application to get a feel for how well it scales on a single
    JVM. Once
    you get a feel for this, it will be easier to get a more realisticestimate that we (BEA and you) can be comfortable with. If you want some
    help with this, please talk to your BEA Account Representative about this.

  • Best SQL Challenege: TSQL Query Maximum Concurrent Connections (Participants)

    Hi All,
    I have a table called dbo.PhoneCalls with below columns
    PhoneID |PhoneNumber| Callstarttime| CallEndtime|
    1 |111-111-1111|2013-04-01 05:13:03.000|2013-04-01 05:13:03.000
    1 |222-222-2222|2013-04-01 05:15:12.000|2013-04-01 05:16:52.000
    2 |333-333-3333|2013-04-01 05:17:29.000|2013-04-01 05:24:08.000
    2 |444-444-4444|2013-04-01 05:21:50.000|2013-04-01 05:22:31.000

    1. PhoneID is nothing but the participant in the call. PhoneID = 1 is twice from above. Which means 2 particpants (Same call
    )with 2 numbers with their callstarttime and callendtime. Similarly for PhoneID =2, there are 4 participants. And the list goes on for a day and then for a month.
    2. For example a phone call P1 with 2 participants is going on for a particular day. We should not consider the same phone
    call having 2 participants involved. So that the concurrency would be 2. We have to ignore that here. 
    3. Only to be considered is other Phone calls for that day. Lets say P1 having call with 2 participants, P2 having some 4 participants
    which fall in the time period of P1. Then we should consider P1 and P2 the common period
    4. In order to find number of concurrent calls happened for a day basing on callstarttime and callendtime. What would be the
    query?
    5. Should consider the Timeperiod or the bucket with 1 hour as the period.
    6. A Phone Call P1, Phone Call P2, should have matching (common) time ( keeping all the scenarios) is required for this query.
    Result for Concurrent calls for a day should be like below. Should get all the concurrent connections happened for a particular
    day.
    Date|TimePeriod/Bucket(hr part)|Concurrentconnections|
    Jan-01-2015|01 to 02|3
    Jan-01-2015|11 to 12|2
    Jan-02-2015|04 to 05|5
    Jan-02-2015|12 to 13|13
    ii) So once the above is achieved.
    Have to find the Maximum concurrent connections for day from the above.
    For below Maximum Concurrent connections are '3'
    Date|TimePeriod/Bucket(hr part)|Concurrentconnections|
    Jan-01-2015|01 to 02|3
    Jan-01-2015|11 to 12|2
    Hence the Result for Maximum Concurrent Connections would be
    Date|TimePeriod/Bucket(hr part)|MaxConcurrentconnections|
    Jan-01-2015|01 to 02|3
    Jan-02-2015|12 to 13|13

    Thanks George.
    That was fantastic.
    But 
    But I don't want  the participants to be concurrent in the same call. And should consider the different call.
    Lets say Phone Call P1 having 2 participants , obviously they are concurrent according to that call.
    Only the Phone calls with more than one participant should match with other phone call with more than one participant.
    A Phone call with any number of participants not matching with the time slot of other phone call should be ignored.
    There might be a different call say P2, having some 3 participants at the same time or atleast fall in P1's time slot.
    So
    P1 --> 2 participants ---> start hour 10:00am  ; End Hour 12:00pm
    P2 --> 3 participants ---> start hour 10:30am ; End hour 12:30 pm
    P3 --> 4 participants ----> start hour 11:00am ; End hour 11:10am
    So the concurrency should ignore for P1 and should consider for P2 and P3. From above P2 having 3 participants, P3 having 4 participants. So the common time for all P1,P2,P3 is 11:00am - 11:10am.
    Concurrency should be
    Starthour    EndHour  ConConnections
    10:00am    11:00am   (2+3+4) ---> 2 for P1, 3 for P2, 4 for P3, because at exactly 11:00am there are 4 participants. So the time bucket or the slab for 1 hour will give us that concurrency at that particular slab. Except that independent
    participants to that call.
    So Result should be
    Start Hour     End Hour            Concurrent Connections
    10:00am       11:00am                      9
    11:00am       12:00pm                      9
    12:00pm       01:00pm                      5

  • What no of concurrent connections can each server serv?

    Ok we're a startup and currently thinking about whether to use flash media streaming server or red5, or progressive streaming with lighttpd.
    In order to make a decision I would like to know how many concurrent streams can flash media server server stream until one has to purchase another license. Do any of you guys have some numbers.
    We will be streaming mp3 at low bit rates, service will be hosted within AWS EC2 (with whatever instances are available there). So if you can post some performance specs that would be great....
    Oddly enough Adobe Sales does not even know the answer... I have heard rumors that high number of concurrent connections is not a really a feature that this product is developed towards.
    Thanks for you answers.

    I'd do some more research before commiting to EC2/S3 at all. I'd also confirm that comment about Wowza streaming from S3... I've never worked with it, but if you're streaming, chances are S3 is just storage, and you're actually streaming from EC2 (I don't think you can run an application on S3... but maybe I'm wrong there)
    The trouble is, regardless of the software, you're still in competition for bandwidth. There's only so much capacity at the network interface of each shared server, and if you happen to land on a busy server, you may find there isn't enough to go around. For stateless applications like HTTP request/response, that's fine, but for apps that require statefull client/server connections, bandwidth and latency issues can prove catastrophic.
    The biggest problem I have with running a streaming server on EC2 (virtualization issues aside), is that they won't disclose hardware or network specs. So, while you can be sure you'll have the memory and processor allocation, it's a crapshoot when it comes to disk time and bandwidth, as you have no real idea how many other instances you're sharing a server with, or what those other instances are doing in terms of bandwidth and disk usage.
    While I don't know any of the specs on the cloudfront service, I suspect those servers are load balanced in such a way that bandwidth is accounted for. In the general population EC2 servers, that's not the case.
    My advice... really research this before you make your deployment decisions. I've come to find that while scaling out is a bit more challenging, dedicated hardware and bandwidth isn't all that much more expensive than EC2, and when you go dedicated, you can actually count on your resources being available to you.

  • Maximum number of concurrent connections using java sockets

    How can we find out the maximum number of concurrent connections that can be handled by a pooled connection server?
    I have a pooled server which creates a predefined number of handlers. Upon receiving a new request it accepts the connection and sends it to one of the handler.
    The solution works well for low number of concurrent connections - < 50 or 100
    But as the number increases there seems to be an issue
    1. Ignoring request even if i increase the handlers
    2. Increase in delay. [I feel that the listening thread is not getting the time slice to go read the socket for new requests]
    Any idea as to how i can solve this?
    Would an NIO socket help [am using the conventional java.io Serversocket, because my clients may not be non-blocking]??
    Any help would be appreciated.
    Anp

    There is no set maximum, but it is in the thousands on most platforms. I have a production server that handles tens of thousands of connections simultaneously. Most likely you have a bug in your code.

  • How do I change concurrently connected users?

    One of the first questions dbassist asks for a custom, hybrid database (others too?) is the number of concurrently connected users.
    Question: How is that number used?
    Question: How do I change that number?
    Thanks,
    Jerry

    I don't think that the information is used directly. I suspect it's used to calculate a reasonable size for the SGA, etc.
    This means that you can't directly change it, but by tweaking the settings in init.ora you can get the same effect.

  • 2000 concurrent connections

    Hello,
    Does Oracle support 2000 concurrent connections? What are the potential problems/bottlenecks? Memory (how much is required), network (TCP/IP), SQL*NET, etc...
    Oracle states that shared server connection require less memory and permits greater scalability. Is it worth the extra configuration? How much memory is saved?
    The OS can be Windows or Unix. Of course we are talking about 64 bit here.
    Is there any documentation concerning this matter?
    Thanks,
    Mark

    Thanks. Great post by Howard for resuming shared server vs. dedicated connection.
    Concerning shared server connections and length of transactions: It is difficult to say what the length of our transactions are as I don't have any figures, all I can say is that we always ask developers to keep transactions as short as possible.
    Does anyone have this type of implementation in production? I would still like to know of any other possible caveats or limitations.
    Thanks,
    Mark T.

  • Concurrent connection / session

    What's the difference between concurrent connection and session?

    Connections and Sessions
    Connection and session are closely related to user process but are very different in meaning.
    A connection is a communication pathway between a user process and an Oracle instance. A communication pathway is established using available interprocess communication mechanisms (on a computer that runs both the user process and Oracle) or network software (when different computers run the database application and Oracle, and communicate through a network).
    A session is a specific connection of a user to an Oracle instance through a user process. For example, when a user starts SQL*Plus, the user must provide a valid user name and password, and then a session is established for that user. A session lasts from the time the user connects until the time the user disconnects or exits the database application.
    Multiple sessions can be created and exist concurrently for a single Oracle user using the same user name. For example, a user with the user name/password of SCOTT/TIGER can connect to the same Oracle instance several times.
    In configurations without the shared server, Oracle creates a server process on behalf of each user session. However, with the shared server, many user sessions can share a single server process.
    Hope this Helps
    Regards
