Maximum number of concurrent WCF connections on Windows 7

I have a WCF service hosted on Windows 7 Pro operating system.
I would like to know if there is some OS restriction for the number of concurrent WCF clients from different IP addresses that interacts with my service. My WCF service could be run under a dedicated console process or under a Windows Service.
I know that there is a 20 limit of concurrent inbound connections to the MS services (like IIS, File Service, Print Services, etc.), but I have my own custom service that I want to use. 
If there is some OS restrictions related to my case, which are the restrictions when using Windows Server OS?
Thanks,

Hi,
There is no any restriction about the Windows Operating System. The configuration of
maxConcurrentCalls, maxConcurrentSessions, and
maxConcurrentInstances only depends on your CPU cores.
Set maxConcurrentCalls, maxConcurrentSessions, and
maxConcurrentInstances to a value greater than 16 * the number of CPUs or CPU cores. For example, on a computer with 8 CPU cores, set
maxConcurrentCalls, maxConcurrentSessions, and
maxConcurrentInstances to a value greater than 128 (16 * 8 = 128) as follows:
<serviceThrottling
maxConcurrentCalls="200"
maxConcurrentSessions="200"
maxConcurrentInstances="200" />

  • 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.

  • Is there a way to control the number of concurrent SMTP connections on Database Mail?

    Las week Rackspace started controlling the number of concurrent SMTP connections and we are now getting the following message when we send as little as 15 messages at a time using Database Mail:
    Exception Message: Cannot send mails to mail server. (Service not available, closing transmission channel. The server response was: 4.7.0 smtp13.relay.dfw1a.emailsrvr.com Error: too many connections from IP xxx.xxx.xxx.xxx)
    We are using SQL Server 2005 and Windows 2003 and we have been doing this since 2006 with no problems
    Is there a way to control the number of concurrent SMTP connections used by Database Mail or the Database Mail external executable DatabaseMail90.exe?

    Hi rkohler,
    Usually, we can use the Database Mail Configuration Wizard or the Database Mail stored procedures to determine the server name and port number for the Simple Mail Transfer Protocol (SMTP) server . In the SMTP server points, we can set or increase the number
    of concurrent connections.
    There is similar issue about database email on SQL Server 2005, you can refer to the following post.

  • Is there a maximum number of Network Filter Drivers in Windows 7?

    I recently tried to install Windows XP Mode on my Windows 7 laptop, and experienced a number of failures...
    According to a post elsewhere on this forum (http://social.technet.microsoft.com/Forums/en-GB/w7itprovirt/thread/00c74bd9-da7b-4acb-ae5a-7112377bc7e2), one of the possible causes of this is if the maximum number of network filter drivers is installed - from Thayu:
    "From your logs, the error is 0x8004a029, which basically indicates that the maximum number of network filter drivers has been reached.
    Could you uninstall any other network filter driver that you think is not necessary and try installing VPC again?"
    So, I uninstalled Cisco VPN, and retried the XP Mode installation, which now worked... However, I am now unable to re-install Cisco VPN - presumably for the same reason...
    The software I have installed that seems relevant is:
    Symantec Endpoint Security
    Checkpoint VPN-1 SecureClient
    Microsoft Virtual PC 2007 (XP Mode)
    So, am I right in thinking the maximum number of network filter drivers in Windows 7 is 3??  Is this configurable??
    This is a really worrying limit for me, as I have a number of customers that I have to be able to connect to, requiring both CheckPoint and Cisco VPN software to be installed... I also require XP Mode to connect by VPN to legacy clients that don't support the MS-CHAP2 protocol, and I'd be stupid to run without Anti-virus...
    Any suggestions?
    Nick

    Hi,
    Based on my research, I would like to answer you that the maximum number of network filter drivers in Windows 7 is 14. However, it is hard coded to allow 14 filter drivers. By default, the number is 8. To view the number or modify the number, please access the following registry key:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Network\MaxNumFilters
    Usually, the network filter drivers are listed in the Network Connection’s Properties. Also, it can be located by some third party programs, such as antivirus program.
    Thanks,

  • How to get Maximum Number of Concurrent users for last few days?

    Hi,
    How I can get maximum number of concurrent users which were logged in to the system (ECC 5.0) I mean I want to check the hostory for last few weeks. Is there any way to get the same? I know that I can get Cumulative number of users in st03 under Expert mode but that is the number of users logged into the system during the day. Is there any place where SAP maintians the High Watermark of Number of concurrent users reached in the system?
    Thanks in advance...
    Regards,
    Pravin

    Sorry I really missed that I have posted a question here on sdn. I wanted to know this for planning the system hardware requirements. Activities like PM ( Performance Management ) happens once a year and during that activity we see heavy user loan on the system so if I have the exact stats of 1 or 2 years data I can size the system better next time. Fortunately last 2 years PM was very smooth for us. In that look for the improvement because each time we had little extra Harware. By doing the exact analysis we can save a Cost of ownership...
    I was looking for R/3 users. I could see the number in st07 but I want to know the exact number at particular time.. I believe that st07 stores only for few days.
    Thanks

  • Maximum number of concurrent devices that could be used with embedde oracle

    Hi,
    How to know what will be the maximum number of concurrent devices that could be used with embedded oracle?
    Any help will be needful for me
    Thanks and Regards

    user598986 wrote:

    I assume you are talking about an Oracle-supplied database engine. Currently Oracle has several database engines: Oracle Database (Personal/Enterprise/Standard/Express); Oracle Berkeley Database; Oracle Times Ten Database; (iirc) InnoDB Transactional engine; and down the road possibly MySQL.
    Many people mean Berkeley when asking this kind of question, but sice you ask it in an Oracle Database forum as compared to a Berkeley engine forum, I am not quite sure.
    If you indeed mean 'Oracle Database', then it is a lecense question that needs to be discussed by you license people and Oracle sales.

  • Maximum Number of Concurrent User Sessions Limit?

    Please can you tell me if there is a limit for the maximum number of concurrent users sessions that can access the Portal? If so, where is the setting and how do I change it?
    By the way, I am not experiencing any issues; I am asking purely for information purposes
    Thanks.

    There used to be under one of the services in service configuration.  I thought it was under portal runtime, but I can´t see it now.  It mentioned it in the TZTEP1 course, but I haven´t got it with me.
    Having said that, I don´t know if it worked!

  • Maximum number of concurrent users in RDC

    Hi
    Can anyone tell me what is the maximum number of concurrent users
    that can view reports running under RDC component ?
    thanks

    The RDC is limited to three concurrent processes. Only reason I was after the craxdrt.dll v.s. craxddrt.dll is that craxddrt requires extra licensing. Anyhow, the article [Crystal Reports XI Release 2 Component Licensing Explained|https://www.sdn.sap.com/irj/boc/index?rid=/library/uuid/804acc00-8364-2b10-b995-de99ca43c403&overridelayout=true] has more detailed information. I understand you are using CR 10 and the doc title is CR XI r2, but as far as the RDC the licensing details remain the same between the two versions.

  • Maximum number of concurrent users

    What is the maximum number of concurrent users any single given Airport can handle? I believe it is ten...
    Thank you!

    If the AirPort is configured to create a wireless network, the AirPort Express can handle up to 10 users. The AirPort Extreme and Time Capsule will handle up to 50.

  • Maximum number of concurrent users that can connect to a SQL DB

    I see various SQL DB plan S0, S1, S2 and P1, P2 and P3.  Each one of them talk about DTU's but never talk about the max number of concurrent users.  Where can I find that number and is it configurable by the end user?

    It is the maximum connection that is most important. Best practice is not to have users holding on to their connection for long period of time. Maximum user connection in SQL is 32767, resource permitting. Not sure for Azure SQL. If you follow best
    practice, you are not supposed to hit this limit cause other limits will be hit first.

  • [Q] Maximum Number of Concurrent Connections to 1142 LAP

    We are having random issues of users not being able to connect to our wireless network consistently. The users will have successfully accessed the network previously but then will have difficulty associating to the network. After a period of time, the association appears successful again. My first thoughts were that there was a restriction on the number of clients that could associate to a given AP at any one time.
    This is the equipment we have:
    1x Cisco Wireless Control Server (WCS) 6.0.181.0
    4x Cisco 5508 Wireless LAN Controllers 6.0.196.0
    60x Aironet 1142N Lightweight Access Points (LAP)
    Is there a hard or recommended maximum number of clients per LAP? If so, where is this defined? From what I have read on these forums, Cisco apparently recommends about 25 clients per AP but I can not find any official documentation to support this.
    When I go to WCS Home > General > Top APs by Client Count, the top AP reports 20 clients. However, if I click on the AP Name and go to the Current Associated Clients tab, it is only listing 8 clients - why is this?
    Any help greatly appreciated.
    Thanks in advance.

    1.  What error messages do the clients get when they are having association/authentication issues?
    There is no error message on the client, it simply fails to connect instantly. On an Android phone, you see it constantly trying to connect, failing and trying to reconnect. After many attempts (at least 10) it may connect successfully. This appears to me that it may be related to aggressive load balancing - here is what I think may be happening:
    Client tries to connect to nearest LAP
    Nearest LAP has to many clients on associated (as detemrined by the RRM Thresholds > Max Clients setting) and so refuses the connection (and sends a code 17 response)
    Client attempts to connect to the next nearest LAP which is also too busy. It too rejects the connection.
    Client attempts to connect to the third nearest LAP which is also too busy. It too rejects the connection.
    And so on until it comes back to the first nearest LAP
    This LAP, which still has too many associated clients, rejects the connection for a second time (its RRM Thresholds > Min Failed Clients is set to 3)
    the clients tries the other APs and is also rejected as they are all set to reject connections for 3 times.
    Client goes round all the APs for a third time. still getting rejected.
    It then attempts a 4th connection to the nearest LAP and is allowed to associated as it is beyong the 3-attempt threshold for rejected connections.
    This is my understanding of Aggressive Load balancing and would seem to match the observed behaviour of the clients but I would like to know if this is correct and how I can verify that in the logs?
    This goes back to my first question, what is the max recommended number of clients for a 1142N LAP? Furthermore, is there any supporting documentation for this recommendation? Also, if I increase the RRM threshold Max clients to more than its default of 12, will the LAP accept more connections before rejecting them?
    I would also like an answer to my second question in the original post.
    2.  Are you using ACS/RADIUS/TACACS?
    We are using 802.1X with ACS for our corporate users on the corporate SSID but the behaviour described above is seen on guest clients that just use web passthrough (i am not sure if it is also on corporate clients, I have not seen any reports to that effect yet).

  • How do you set maximum number of concurrent users to OBIEE

    In a training session for the end users - only 4 users could connect - after this others could not connect - got NQS Error:100118 Access for the connection is refused

    As I don't see any configuration tag to specify concurrent users.
    Try this, go to connection pool (within RPD) and set the maximum number of connections, this does correspond to number of concurrent connections to database but not concurrent users.
    mark posts promptly.

  • Scalability in BlazeDS - What is the maximum number of concurrent users possible with BlazeDS?

    Hi all,
    is there a limit on the number of concurrent users that can connect via BLAZEDS? I see many places that it is only in 100s and not in 1000s.
    is that true? Anybody has doen performance testing on that?
    Thanks

    What is practical? Probably between 1 and 6 streams can be done with reasonable use of bandwidth. However, keep in mind that you will likely want to use the lowest quality setting for cameras so they are demanding the least amount of bandwidth.
    Using the Connect 8 numbers, Low quality webcam video with the room at LAN settings should have an aprox average bandwidth consumption of 184 kbps. From there it is just simple math. 6 live streams at that setting will be 1.1 Mbps. Alternatively, at High quality webcam video and with the room at LAN, each stream will average aprox 501 kbps. 6 streams will average 3 Mbps.

  • Maximum number of tcp/udp connections

    I've got a WRT54G and recently I contacted linksys suport due to some problems I was having with
    BitTorrent clients(very common issue it seems). I have a home lan with 3 computers,
    and if 2 or more of them are on at the same time(even when only 1 is using bittorrent), the connection keeps going
    down.
    Linksys support told me a lot of routers face this problem since bittorrent works by opening lots of simultaneous
    tcp/udp connetions, and one thing I should do is try to limit these connections to a number the router can handle.
    Even though I might experience some poor speeds limiting connections, it seems it's all I have left. So, not a
    problem at all, except one question which brings us to the purpose of this message:
    Approximately HOW MANY TCP/UDP CONNECTIONS can WRT54g handle at the SAME TIME?
    Since I'm to share among 3 users, all of which are torrent freaks, I'm gonna have one heck of a hard time tryin' to
    guess the maximum number of connections each should have, specially when they're all on at the same time.
    Support said they don't have that information. So does anyone out there have a good guess?
    And also, does anyone know of any Linksys router (for home use) that is able to work with torrents without any
    problem at all?

    The wrt54g(s) upto v4 and the wrt54gL use a Linux 2.4.20 kernel.
    This Linux-kernel set a max of 1024 connections and a hastable of max 128 buckets, the gs models with 32 Mbyte have 2048/256.
    I see three problems:
    1. The following patch is not applied to the kernel: Netfilter / connection Tracking Remote DoS, CVE: CAN-2003-0187
    2. The hashsize is wrongly set, de default kernel 2.4.20 values are wrong, and may NOT be an even number (128), it should be a prime number.
    3. The ratio between hashsize and max amount of connections should be set to 1 and not 8, this to increase performance.
    Some improvement is made by Linksys in firmware version 4.21.1 and 4.30.9 (are neerly the same) .
    I hope this information helps,
