Several connections open db in a weblogic cluster

We have created a weblogic with oracle database cluster.
Whenever we start the cluster (managed server), there are a lot of connections open in the database (about 150 in the database). Although we have a maximum capacity of cgDataSource, cgDataSourcenoXA and wlsjmsreportDS 20. So ideally should be not more than 60 connections open at any time.
We use 10gR 3 OSB in 64-bit Linux platform.

The maximum capacity for a data source is by node in the cluster (if it is targeted on the cluster).

So if you have 3 sources of data, with a maximum capacity of 20 nodes of each and two in your cluster you should have about 3 * 20 * 2 = 120 connections.

Of course to start WebLogic creates only the number of connections specified in the initial capacity.

  • How to operate with several connections open for VCs (Connect-VIServer).

    Hello:

    I know that I can open multiple connections to VCs (Connect-VIServer), but do not really understand how to run with them...

    How can I speak in VC1 for a single operation and after that VC2 to another without closing the connection in VC1?  I might need to do this several times in my script...

    Any help and simple example will be really appreciated.

    Thank you

    qwert

    The cmdlet Connect-VIServer of PowerCLU 4u1 leave takes supported several open sessions.

    The sessions are stored in a table called $defaultVIServers.

    If you need restore an open session, you can use the entry for this server in the array and then use the SessionId property to make this session open session / by default (which is stored in the variable $defaultVIServer).

    Something like that

    Connect-VIServer -Server VC1
    Connect-VIServer -Server VC2
    # Show the sessions and their properties
    $defaultVIServers | Select *
    
    # Open the session to VC1
    Connect-VIServer -Session $defaultVIServers[0].SessionId
    
    # Open the session to VC2
    Connect-VIServer -Session $defaultVIServers[1].SessionId
    
    # The open session
    $defaultVIServer
    
  • Whenever I try to open a new tab in Safari, it closes in on my previous page. How should I do so that I can have several tabs open?

    Whenever I try to open a new tab in Safari, it closes in on my previous page. How should I do so that I can have several tabs open?

    What version of OS/Safari do you use?

    Try a reboot.

    Make a backup using Time Machine or a cloning program, to ensure that data files can be recovered. Two backups are better than one.

    Try to set up another admin user account to see if the same problem persists. If back to my Mac is enabled in system preferences, the guest account will not work. The intention is to see if it is specific to an account or a system wide problem. This account can be deleted later.

    Isolate a problem by using a different user account

    If the problem is still there, try to start safe mode using your usual account.  Disconnect all devices except those necessary for the test. Shut down the computer and then put it up after a 10 second wait. Immediately after hearing the startup chime, hold down the SHIFT key and continue to hold it until the gray Apple icon and a progress bar appear. Startup is considerably slower than normal. This will reset some caches, forces a check for directory and disables all start-up and connection, among other things. When you restart normally, the initial restart may be slower than normal. If the system is operating normally, there may be 3rd party applications that pose a problem. Try to delete/disable the third-party applications after a reboot using the UN-Installer. For each disable/remove, you need to restart if you do them all at once.

  • keyboard no one and several windows opens automatically

    The last few days Ive seen the following problems with my laptop:

    1. on a normal startup

    several windows open automatically without prompting to the keyboard. The first window is usually the Help window, and then opens the default browser window as well. 10 - 15windows opens in a duration of one minute and continue until I manually closethem or at the end of the process in the Task Manager.

    This experience on the admin user and others

    2. Alternatively on the boot of startup window stops and asked to choose an operating system.  This machine has only win7 on it. no option cannot be selected as keyboard stubbornly inactive you.

    3.

    If by chance the machine decides to start, I can not connect to the user, because the keyboard is not responsive

    If I get the admin user for which I have no password... anything can be typed keyboard non-responsive rest like a potato.

    It seemed that the keyboard was defective, so ive got changed, but the problem persists.

    Help, please.

    Of course, it looks like infections are present.

    Run ADWcleaner https://toolslib.net/downloads/viewdownload/1-adwcleaner/ it's free and one of the only malware cleanup tools that I trust.  Malwarebytes can be used, but be careful to not take the trial or use the pro version.  Virtually all the removal tools known as maleware are in themselves of malware.

    If you are unable to get sufficient control, download ADWcleaner into the USB port on another computer.

    Tools, Internet Options, advanced.

    Multiple OS question at the start is usually someone re - install Win7, but unless you first delete the existing partition.

    Now, this is a controversial subject, but your choice of AV software may be something you want to take a 2nd look.  I suggest you visit this website to get an idea of what AV software made the best work, depending on what type of user you are: http://www.av-comparatives.org/ is a non-profit that has been around for a long time and I hope that their results.

    When you interpret these results, remember the difference between a product that detects 95% and the other 99% of infections, it is actually 5 times more likely to allow an infection.

    I care about 140 Windows PCs and I have more than 13 years.  Until last September, the only AV software that I would allow my clients to use was Norton Antivirus.  Note that this is not the same as any other product, Norton 360 or Internet Security.

    Last September, Symantec (Norton owner) decided to no longer sell such a product.  After much research, I decided on Bitdefender Antivirus 2015 +.  I installed it on more than half of these PC so far and has never been a problem.  In fact, I think it's a better product than even Norton.  One of the things I love the most about it, is the silence and discretion.  It is also cheap.

    My customers know that if they install any product of 'Internet Security', I won't work on their computers until it is deleted.  Very well, I learned the hard way that the other components of these products (other than the AV itself) IS caused more problems than any profit that they bring and work primarily by stopping the Windows component that does a very good job of this particular task still.  My problem is that when I started to work on a computer with an IS on it, I could spend hours trying to diagnose the problem, only to find out that by taking the product of the IS, the problems have become much clearer and easier to solve.  I think that the product of the IS actually hides the problem.

    As I said.  It is a controversial topic and you will find many different very strong opinions.  I know that mine is based on a fairly large sample over a long period, and are consumers of consumer type Windows.

    Another thing you need to know: you can delete not entirely of most any AV software simply by using the standard uninstallation tool Windows 7.  Most of the majors also publishes a "removal tool" that gets the rest.  If you do not completely remove it, it will cause very hard to understand and diagnose problems.

  • When there are several tabs open, why the search always take place on the 2nd tab (first tab seems never to change the homepage) despite my selection of a different tab where to do a search on google?

    I have Mozilla Firefox 10.0. When I open it, it opens properly on the homepage in the first tab. Once I have another, or several, tabs opened, any tab is active, your google searches, I immediately takes place at the No. 2. Do not count how many times I go to the tab for example 4 to search (because I would compare with the page Web open in a tab 2), but it does still today the Search tab 2. It's very irritating. It must be a setting that went pear-shaped, but where / who? Any suggestions? Thank you.

    Try Firefox SafeMode to see how it works there.

    A way of solving problems, which disables most of the modules.

    (If you use it, switch to the default theme).

    • You can open the mode without failure of Firefox 4.0 + by pressing the SHIFT key when you use the desktop Firefox or shortcut in the start menu.
    • Or use the Help menu option, click restart with the disabled... modules while Firefox is running.

    Do not choose anything at the moment, just use 'continue in safe mode.

    To exit safe mode of Firefox, simply close Firefox and wait a few seconds before using the shortcut of Firefox (without the Shift key) to open it again.

    If it's good in Firefox Safe mode, your problem is probably caused by an extension, and you need to understand that one.

  • Scanning preview. He made several PDF opens at the same time. Combine one?

    I use a scanner to digitize old financial records as pdf with preview files.

    The problem is if you do not do so in a single batch, the result is that you do not get a single pdf file. You end up having several files opened, named "Untitled", "Untitled 2", "Untitled 3" etc. "

    Is it possible for one) avoid what is happening in the first place? or (b) just tell the computer to merge files into a single pdf file?

    If I could do it easily the whole operation would be less stressful.

    I think remember me something useful:

    close the preview.

    Select all the files you want.

    Drag them (in a group) on the preview icon.

    In Firefox 3, when I got to close the program to have several tabs open, Firefox asked me if I wanted to save and remember the tabs open, so that I can get them at the next restart of Firefox.

    Yes, it is very likely. Try disabling the firewall and try again. If the code works when you run the Server & client on your machine, but not when you run the server on your NAS and client on your machine (assuming you have entered the correct port for the NAS server), then it is very likely to be a firewall problem.

    Server that is listening is no longer VI also means what.

    Your VI server listens only once for a connection after receiving an incoming connection (or it expires after 60 years), he stops listening and the port will be more open for incoming connections - you must re - run the VI for another connection. With your code, you must run the VI server and then run the VI client in the 1960s, so it's not expire.

    When multiple tabs open, Firefox ask me never confirmation when I click Firefox close window button in the corner (usually accidentally). And I would like confirmation.

    about: config I have:

    true browser.showQuitWarning (it is marked as custom value (bold), default is false)

    true browser.tabs.closeWindowWithLastTab

    and when I close Firefox (usually accidentally) I get window of journalist of crash that I submit usually.

    Update: claims of a member who never close the confirmation appears for only one Firefox window, only several windows of Firefox. According to me, that this is of people probably half of bad idea is not using multiple windows, only the multiple tabs.

    Is it possible that I can start my server managed by Admin? If Yes, what are the steps I have to do to make it viable.

    In addition, which is just how to configure the node Manager autostart administrator and Manager on the same host and server with the single domain.

    NodeManager cannot start Admin and the managed server automatically when you gracefully stop the managed server.

    Recovery setting enabled the crash work in case of a sudden collapse of the host itself. This does not mean that NodeManager servers will automatically start every time. Crash Recovery also works for servers that are started by using Nodemanager only.

    For:

    Error: Exception thrown by the agent: java.rmi.server.ExportException: Port already used: 9899; nested exception is:

    exception java.net.BindException: address already in use

    As says error itself port is already in use. Be sure to use the single port and also check if a process taking into this port.

  • How can I minimize Firefox in one click when I have several tabs open?

    I used to be able to minimize Firefox with a single click on the icon in the taskbar, even with several tabs open. Now it doesn't let me. Now, when I move my mouse over the FF icon, a pop-up shows all open tabs and I need to find another way to minimize Firefox. I'm missing something here.

    I was right. I unchecked the box in the options that says "show previews of the tab in the Windows task bar" and everything works as I want it now. Thanks again for your help. These things are usually easy to fix, but hard to find sometimes.

  • 12.1.0.2 managed Oracle data provider running significantly worse than classic ODP on Connection.Open (3 sec vs 0.2 seconds)

    Oracle managed provider has many advantages over the traditional Oracle for .net data provider.

    However, our test shows who take connection.open 3 seconds, where the classic ODP takes 0.2 seonds. Opens later against the same connection string perform the same way for the two (0.1 seconds). Subsequest opens against a new connectionstring (another basic data) take 2 seconds for the managed provider and 0.1 second for classic.

    This is not acceptable in some cases, but may be supported in others.

    Someone at - it seems a similar behavior? Any suggestions that may improve the performance of connection.open?

  • Doubts about Weblogic Cluster and application deployment

    Hi all

    WebLogic...: 12.1.2

    ... OS: AIX 7.1

    We intend to create a Weblogic cluster at 2 knots in different sites to comply with the requirements of the customer HA. With this in mind im a few doubts began to rise:

    (1) this solution will have a server in site A Weblogic and an another Weblogic Server on site B, and we will create a Weblogic cluster with these 2 servers. It is equivalent to an Oracle extended RAC, but with Weblogic. Our link between sites is extremely fast, dedicated, with a latency of less than 5 ms. Is it possible and cost-effective to build such a solution?

    (2) regarding the deployment of the application, I would like to know if it is possible to deploy an application on Weblogic Server just on node A, and this application is automatically replicated on the Weblogic Server in site B? As far as I know, I have to deploy the application on both Weblogic servers manually.

    Thanks for the patience and attention.

  • Help on consistency + Weblogic Cluster configuration

    Hello

    I am new to consistency. I explore the consistency to fill one of my condition.

    My needs: I have an application deployed on a clustered server logical Web environment. I need to cache data specific to the application (java card) and that should be available to all nodes in the cluster WLS. Application that are cached, data can be updated from any of the node in the cluster WLS and updated the application cache data should be available for all the nodes in the cluster WLS. The nodes in the cluster of WLS resides in different machines from different places.

    Can I use coherence as a services of caching for my requirement?

    If Yes, do I need to start a server cache consistency on each node of the cluster WLS?

    If so, do I need to specially configure these servers cache, so that these cache servers would communicate each other in case of updates of data in the cache?

    It will be very helpful if you could also provide sample configurations to achieve the above scenarios.

    Thanks in advance!

    Kind regards

    You can start a cache server in the network by using for example

            movies = CacheFactory.getCache("repl-movies");
            movies.put(10, new Movie(10, "Rear Window", "Alfred Hitchcock"));
            movies.put(20, new Movie(20, "Vertigo", "Alfred Hitchcock"));
            movies.put(30, new Movie(30, "Double Indemnity", "Billy Wilder"));
            movies.put(40, new Movie(40, "Touch of Evil", "Orson Welles"));
        }
    
        protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
            Integer[] integers = {10, 20, 30, 40};
            Random random = new Random();
            while (true) {
                movies.get(integers[random.nextInt(4)]);
            }
        }
    }
    

    Package the servlet into such a WAR file and deploy it in a WebLogic cluster configured.

    By accessing the servlet on the different nodes in the cluster a new cache is created and added to the
    already running DefaultServer.

    The most difficult part is to configure your cache. As you can see in servlet initialization we EU something like CacheFactory.getCache ("repl-movies");
    Lack of consistency with some configurations of cache example that are contained in the coherence.jar (coherence-cache-config. (XML).
    The following entry is used

    
          repl-*
          example-replicated
    
    
          example-replicated
          ReplicatedCache
          
            
              unlimited-backing-map
            
          
          true
    
    

    A replicated cache is probably what you need as well. You like all the data available on all nodes. If you want to use
    your own cache configuration, you can add the option - Dtangosol.coherence.cacheconfig (see the for the default server startup script)
