Clients connections not balanced across proxies

Guys,
I have 8 Extend clients connecting to 6 proxies. With 3.7, my understanding was by default clients connections should be balanced across available proxies but its not the case always. I see some times client connections are not load balanced at all.
Have been through -- http://docs.oracle.com/cd/E24290_01/coh.371/e22839/gs_configextend.htm#BEBBIJAI
I've specified two proxies in the client side config
          <tcp-initiator>             
           <remote-addresses>
               <socket-address>
                  <address>35.54.42.46</address>
                  <port>9099</port>
               </socket-address>
               <socket-address>
                  <address>35.54.42.47</address>
                  <port>9099</port>
               </socket-address>
            </remote-addresses>
               <connect-timeout>10s</connect-timeout>
            </tcp-initiator>
Haven't configured load balancer on the proxy, so by default it should be set to 'proxy'. Have even tried by explicity configuring load balancer to 'proxy' bo luck.
Certain times I see, which is perfect
     proxy 1 -- 1 client connection
     proxy 2 -- 2 client connection's
     proxy 3 -- 1 client connection
     proxy 4 -- 1 client connection
     proxy 5 -- 2 client connection's
     proxy 6 -- 1 client connection
But I also see
     proxy 1 -- 1 client connection
     proxy 2 -- 3 client connection's
     proxy 3 -- 0 client connection
     proxy 4 -- 0 client connection
     proxy 5 -- 1 client connection
     proxy 6 -- 3 client connection's
Any ideas to fix this would be appreciated.
Thanks

Hi Venkat,
Been monitoring RequestTotalCount, but I still think connections still imbalanced..
Currently, I have 3 clients and 5 proxy nodes and i see
Proxy node 1 ---  ConnectionCount=2, RequestTotalCount=25
Proxy node 2 ---  ConnectionCount=0, RequestTotalCount=23
Proxy node 3 ---  ConnectionCount=0, RequestTotalCount=4
Proxy node 4 ---  ConnectionCount=0, RequestTotalCount=18
Proxy node 5 ---  ConnectionCount=1, RequestTotalCount=19
Would appreciate your clarification. Also, shound't client connections be balanced based on 'ConnectionCount' and other attributes like CPU usage, etc?
Thanks
K

  • Thin Client connection not failing over

    I'm using the following thin client connection and the sessions do not failover. Test with SQLPLUS and the sessions do fail over. One difference I see between the two different connections is the thin connection has NONE for the failover_method and failover_type but the SQLPLUS connection show BASIC for failover_method and SELECT for failover_type.
    Is there any issues with the thin client the version is 10.2.0.3

    Example: TAF with Connect-Time Failover and Client Load Balancing
    Implement TAF with connect-time failover and client load balancing for multiple addresses. In the following example, Oracle Net connects randomly to one of the protocol addresses on sales1-server or sales2-server. If the instance fails after the connection, the TAF application fails over to the other node's listener, reserving any SELECT statements in progress.sales.us.acme.com=
    (DESCRIPTION=
    *(LOAD_BALANCE=on)*
    *(FAILOVER=on)*

    *(FAILOVER_MODE=*
    *(TYPE=select)*
    *(METHOD=basic))))*
    Example: TAF Retrying a Connection
    TAF also provides the ability to automatically retry connecting if the first connection attempt fails with the RETRIES and DELAY parameters. In the following example, Oracle Net tries to reconnect to the listener on sales1-server. If the failover connection fails, Oracle Net waits 15 seconds before trying to reconnect again. Oracle Net attempts to reconnect up to 20 times.sales.us.acme.com=
    (DESCRIPTION=
    (ADDRESS=

    Hi
    I have a Wireless-g broadband router (wrt54gs) and i want to connect to citrix. I can ping the remote host but I can not connect to it using my citrix client. (not with LAN not with WIFI). If I put my computer directly behind the internet I can connect in a second to citrix.
    I have already opened a bunch of ports 1640 1494 2598 2513 2512 1433 by adding these ports in the "port range forward" section. 
    Could somebody point me in the right direction.

  • Database connection not working across all Adobe programs

    I have a PDF form connected to an Access database via ODBC. On the form, I created a button that, when clicked, takes the data in the PDF and adds it to the database. The scripts for that action and the connection was established in LiveCycle Designer. I opened the PDF in Acrobat Pro and enabled Usage Rights for Reader (overwriting the file in the process). Here's what I find odd. The button works fine in Acrobat Pro, but when I open the PDF in Reader and try the button, it gives me an error saying that the accessor 'xfa.sourceSet.DataConnection.open();' is unknown. Why on earth would Adobe recognize the connection in Acrobat but not in Reader? That doesn't make sense to me, especially since I did enable the usage rights.

    I do not see where this permission is given in the enablement of Acrobat Professional Forms. What I see is the following:
    - Save form data
    - Commenting and drawing mark-up tools
    - Sign an existing signature field
    - Digitally sign the documen anywher on the page (only supported in Adobe Reader 8.0)
    I do not see connect to a database anywhere.

  • Http Active requests not balanced across OAS Farm

    Hi,
    i have a Farm with 4 OAS , repository file based and 10.1.2 OAS version.
    The Http active request it's very different along the 4 nodes. In two nodes i have more than 2000 respectively and in the others only 40.
    The http active connections it's very different too in 150 to 45.
    Otherwise, the throughput it's similar in all 4 nodes, total Requests Processed Since Startup it's similar too and

  • Load balancing across database connection

    Do you provide load balancing across database connections and allow RDBMS load
    balancing for read only access?
    Thanks in advance.

    Hello, Christina.
    Load balancing with multiple machines is a little bit different than
    in the same machine. One of the important resource in this kind
    of application is network bandwidth, so tuxedo tries to keep the
    traffic among the machines as low as possible. So, it only
    balance the load (call services in other machine) in case all the
    services are busy in the machine where they are call.
    I mean, if you have workstation clients attached only to one
    machine, then tuxedo will call services in this machine untill
    all servers are busy.
    If you want load balancing, try to put one WSL in each machine,
    and the corresponding configuration in your WSC ( with the | to
    make tuxedo randomly choose one or the other) or spread your
    native clients among all the machines.
    And so, be carefull with the routing!

    Hi Jason
    I was getting the same behavior after Apple support had me delete some plist files to get Airplay going. I was also getting the following error:
    the error occurred while processing a command of type 'writesettings' in the plug-in 'server vpn'
    I went into ~/Library/Preferences/ and /Library/Preferences/ and deleted every plist contating the word server. I had to re-set up my server (meaning walk through some intial steps) but all of my settings were still there after that and everything started working again.
    Just a thought, obviously try at your own risk but it worked for me.

    Solution:

    case 1: when the password is wrong
    case 2: when you try to login from some App
    case 3: when you try to login from the domain other than your time zone/domain/computer (This
    is the case in most of scenarios when sending mail from code)
    There is a solution for each
    solution for case 1: Enter the correct password.
    Recomended: solution for case 2: go to
    security settings at the following link https://www.google.com/settings/security/lesssecureapps and
    enable less secure apps . So that you will be able to login from all apps.
    solution 1 for case 3: (This might be helpful) you need to review the activity. but reviewing the activity will not be helpful due to latest security
    standards the link will not be useful. So try the below case.
    solution 2 for case 3: If you have hosted your code somewhere on production server and if you have access to the production server, than take remote
    desktop connection to the production server and try to login once from the browser of the production server. This will add exception for login to google and you will be allowed to login from code.
    But what if you don't have access to the production server. try
    the solution 3
    solution 3 for case 3: You have to enable
    login from other timezone / ip for your google account.
    to do this follow the link https://g.co/allowaccess and
    allow access by clicking the continue button.
    And that's it. Here you go. Now you will be able to login from any of the computer and by any means of app to your google account.

    ORA-12518: TNS:listener could not hand off client connectionDon't do Oracle on Windows, so I'm not sure how the following relates to the Listener dealing with a dedicated server connection request on Linux/Unix.
    On Linux/Unix, a dedicated server request means just that - a dedicated process has to be started to service that client. The Listener does it by using the parameters of the configured listener.ora service to execute +$ORACLE_HOME/bin/oracle+. This process then starts up, and the Listener hands off the client connection for this process for servicing.
    If there is a failure somewhere on this series of steps fail, the Listener throws the ORA-12518 exception. For example, the +$ORACLE_HOME+ has been incorrectly configured in listener.ora and it fails to execute and startup a dedicated server process.
    And this relates to the underlying error you are seeing:
    TNS-12518: TNS:listener could not hand off client connection
    TNS-12560: TNS:protocol adapter error
    TNS-00530: Protocol adapter error
    32-bit Windows Error: 2: No such file or directoryI think that the Listener on Windows uses the CreateRemoteThread() Win32 call to start up the server process thread. However, it needs a valid process identifier (of the existing Oracle instance) for this call - and thus needs to first identify the Oracle instance process. Could be that this step uses a ORACLE_HOME reference. And if that directory path is not valid, it is unable to identify the process id of the Oracle instance and thus unable to spawn a dedicated thread to service that client.

  • TNS:listener could not hand off client connection

    while trying to select from dblink I got ORA-12518: TNS:listener could not hand off client connection
    What should I do?
    here is the listener.ora
    SID_LIST_LISTENER =
    (SID_LIST =
    (SID_DESC =
    (SID_NAME = PLSExtProc)
    (ORACLE_HOME = C:\oracle\product\10.2.0\db_2)
    (PROGRAM = extproc)
    LISTENER =
    (DESCRIPTION_LIST =
    (DESCRIPTION =
    (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
    (ADDRESS = (PROTOCOL = TCP)(HOST = disater)(PORT = 1521))
    )

    What is the operating system and database version for remote and local machines.
    Are you using dedicated or threaded server on the remoted DB. More information is needed.
    output from error message search:-
    12518, 00000, "TNS:listener could not hand off client connection"
    // *Cause: The process of handing off a client connection to another process
    // failed.
    // *Action: Turn on listener tracing and re-execute the operation. Verify
    // that the listener and database instance are properly configured for
    // direct handoff. If problem persists, call Oracle Support.
    // *Comment: The problem can be worked around by configuring dispatcher(s)
    // to specifically handle the desired presentation(s), and connecting
    // directly to the dispatcher, bypassing the listener.

  • The client connection is not allowed on the internal edge of the Access Edge Server

    We are trying to setup Lync 2013 Edge Server, we have a setup as described below
    Real IPs for Lync Edge/WebConf/AV
    NAT of real IPs through Firewall Juniper to FE IP
    Topology with NAT (Firewall IP) IP enabled
    Certificates for with SAN for sip.acme.com etc (Both certs are Client Server Auth Templates from Internal MS CA)(Trusted) on Edge
    Route  192.215.0.0 255.255.255.0 gateway (=firewall internal ip address)
    But when external user connects and we are tracing the connection we are getting below error and lync client is 
    not able to connect.

  • [HELP] 10g error TNS-12518: TNS:listener could not hand off client connecti

    Hi all,
    TNS-12518: TNS:listener could not hand off client connection
    (when I do a sqlplus, it hangs for one two minutes, then the error above shows)
    My oracle 10g is installed in a windows system. this error only happens when the database is heavily used for some time. After I restarted the Listoner, the connection is ok again. Does anyone has a solution for this? Thanks a lot.
    Jason

    Monitor your page file usage on Windows system (I assume its a 32 bit machine). When Windows starts to swap Oracle SGA into page file., you encounter TNS errors. Strange but we have observed this.
    If you can allocate more free physical memory on the server (by removing unwanted applications from the memory), then you can reduce these errors.
    Permanent solution would be to add more physical RAM (with 4GT on 32 bit) or switch to 64 bit architecture.

    Typo corrected and added following.
    You can set DIRECT_HANDOFF_TTC_LISTENER=OFF in listener.ora and restar the database as temporary solution. Check metalink Doc ID: 233747.1
