Stress test on an HyperV server.

I have just installed my 1st HyperV server and it seems a bit sluggish.
Does Microsoft have a program to stress test the system(CPU, memory, NIC, Harddrive) and provide a report...?
Thanks,
Tom...

"Copying a file" now requires context.
The management OS?  Within a VM? To a VM from the Management OS?
Where are the VMs stored?  Where was the file stored?
There is a large amount of context that is required to respond to your statement.
Could the addition of Hyper-V impact the time it takes to copy a file?  Possibly.  But this is a huge; 'it depends' type of answer.
Can you stress your server?  Yes.  Can you compare these results against servers without Hyper-V installed?  No, not really.  Everything is now different.

  • Exception only occuring during stress test

    We are trying to get ready to release a beta version of the software I'm working on.. so part of getting ready for that was to try set up some stress tests and hit the server with multiple requests for the same page....

    From the API on java.text.SimpleDateFormat
    Synchronization
    Date formats are not synchronized. It is recommended to create separate
    format instances for each thread. If multiple threads access a format
    concurrently, it must be synchronized externally. Being static, your date format object will be accessed by multiple threads.
    Solution: Don't make the date format object static.
    I would suggest like this:
    private static final String dfString  ="yyyyMMdd";
    protected String formatYyyyMMddToLocaleStr(String  xxxxxxxxDt, Locale locale) {
      String result = "";
      SimpleDateFormat xxxxxxxxDateFormat = new SimpleDateFormat(dfString );
      if ( xxxxxxxxDt != null &&  xxxxxxxxDt.length() == 8) {
      try {
        Date tempDate =  xxxxxxxxDateFormat.parse( xxxxxxxxDt);
        result = javaDataTypeToString(tempDate, locale);
      catch (ParseException ex) {}
              return result;
    Ok, so it is constructing a DateFormatting object for each method call, but I don't see it as that big a deal. Its not a huge hit. You might get away with making it an instance variable - I don't know how you use the enclosing class. Start with this, and see if it works.

  • Server stress testing tool

    Hi all,
    I have been developing an application to do a stress test on our Instant Messenger server. This application must check if server can handle 1000, 10,000 or 100,000 connections concurrently.
    - Server is developed by using socket, it will create a new thread everytime it receives a incoming connection.
    - On the client-side, my application will establish connections to server, each connection is a thread as well.
    The application just need to work with LOGIN and SEND MESSAGE functions
    Here is my testing:
    * With single PC: it runs well with 10, 100 connections, but when I increase number of connections to 1000, 3000... it just takes to long to run all the connections, sometimes it also get connection timeout.
    * With 4 PCs:
    If I have 1000 connections, each PC will handle 250 connections, and these 4 servers run at the same time.
    The problems still occurs when number of connections is increased, sometimes it still get connection timeout.
    Am I doing the right things here? Do you have any suggestions for this scenario? Plz help
    Regards,

    I've done stress testing with a laptop for up to 3000 connections. After that I got various resource exhaustion problems. You need to start new threads at the client as well as the server for each connection, or use NIO as I did.
    To test up to 100,000 you will definitely need a number of client machines.

  • Microsoft Project 2013: Project Server Stress Testing

    Hi
    I hope someone can help me. We need to perform some stress testing on Project Server 2013.
    All the articles I found on TechNet suggest that I use the Project Server 2010 Performance Lab Kit
    But it seems like the solution has been archived. (pj14stresstesting)
    All the links refer to http://archive.msdn.microsoft.com/ but the solution is no longer listed.
    Does anyone still have a copy somewhere that they can share with me?
    Or maybe know where I can find it online?
    Thanks

  • Weblogic server terminated abnormally when doing web stress test

    Hi folks,
    I used MS Web Application Stress Test tool to test our web application deployed
    on weblogic server 6.1 sp2. I set the tool to run with 20 threads concurrently.
    And I recorded a script with 300 requests and there are 10 milliseconds delays
    between each request. After running that test for one hour or so I got an ArrayIndexOutOfBoundsException.
    The welogic server was dead. I had to kill that process to restart the server.
    I tried this testing procedure serveral times. Sometimes I came across the same
    problem, but sometimes didn't.
    The machine running WL6.1 is a Red Hat Linux server with 2 CPU and 1 GB RAM.
    Does someone knows why this occurs and how to prevent this problem?
    Thanks to anyone who give me some advise.

    Hi Francisco,
    I run MS web application stress test tool on a Windows 2000 machine as client.
    It access weblogic server running on a Linux machine throught HTTP request. You
    may download this tool from Microsoft web site. It is free.

  • Server socket stress test?

    We have a server socket running.  We have simple client programme as below. We would like to do a stress test on our server socket by running the codes below. How can we achieve a parallel effect with the following codes? Normally what limitation will the socket application have e.g. number of socket per minute etc?
    [code]
    public class stress1 extends Thread {
    public static void main(String[] argv) {
    try {
       for (int i = 0; i < 5000; i++) {
            Socket socket = new Socket("localhost", 18000);
            PrintWriter out = new PrintWriter(socket.getOutputStream(), true);
            BufferedReader in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
            out.println("data to my server ");
            System.out.println(in.readLine() + i);
                 out.close();
            in.close();
            socket.close();
        } catch (Exception e) {
          e.printStackTrace();
    [/code]

    Of course you can.  JMeter is a testing tool.  You can use it for functionality tests, stress/load tests, etc.  And those test cases can be completely customized especially since you can write JUnit tests and use those for the functionality and simply let the framework handle the load portion of it (i.e. how often, for how long).

  • Weblogic server hangs during stress-testing -- possibly EJB deadlocks

    Hi
    While running stress tests on our application, our WLS 4.5.1 hangs even at a
    mere load of 20 users. We are running on a Solaris machine. Database: Oracle
    8.1.5, running on the same machine. Using oracle.jdbc.driver.OracleDriver as
    the JDBC driver, and using JTS as the transaction manager.
    When we did a thread dump (complete lis at the end of this post) and
    basically we are seeing a bunch of our entity beans in a "locked" state. A
    common pattern we see in the thread dumps is that
    [1] weblogic.ejb.internal.BaseEJBContext.lock(BaseEJBContext.java:180)
    [2] weblogic.ejb.internal.StatefulEJBCache.bind(StatefulEJBCache.java:250)
    [3]
    weblogic.ejb.internal.StatefulEJBObject.getContextForInvoke(StatefulEJBObjec
    t.java:88)
    [4] weblogic.ejb.internal.BaseEJBObject.preInvoke(BaseEJBObject.java:164)
    [5] com.nps.ers.ejb.organization.<Our Entiy Bean>EOImpl.<a get
    method>(ERSSystemConfigurationBeanEOImpl.java:1539)
    [6] com.nps.ers.ejb.awardnomination.<Our entity bean>.<some method>
    After more thorough studying of EJB transactions, we changed the isolation
    level of all our beans from TRANSACTION_SERIALIZED to
    TRANSACTION_READ_COMMITTED and made sure all our beans say TX_REQUIRED for
    their transactionAttribue. Still, this problem persists.
    The basic scenario we are load testing is that of multiple users logging
    into the system and trying to access a particular user's record, and right
    now, this is causing deadlocks at 20 users.
    What we fail to understand is that --
    (a) even if a method is attempting a read-only access to the data, why would
    it try to obtain a lock? or why would it matter that the data is locked?
    Some of the locks we are seeing are actually on a bean that is used for
    read-only purposes.
    (b) if 2 or more processes are trying to access the same record, based on
    whichever process got their first, shouldn't one succeed, and the other go
    into a 'waiting' state?
    We have also opened this issue with weblogic support, and the response so
    far has been that there "may" be a bug in weblogic 4.5.1 itself that's
    causing it, and they need to look into it further. Other similar posts in
    the newsgroup haven't been resolved either -- hence this general plea for
    help. Please advise if you've any suggestions. Thanks

    Can you post details on this instrumentation?
    I know in the past when we ran into this type of problem, it took us a while
    to think through and identify the problems.
    Thanks,

    Generally this indicates a deadlock in the order that you access your
    entity beans. Please follow-up with [email protected]. There is
    some instrumentation that you can turn on to help spot why this is
    occurring.

    Hi
    While running stress tests on our application, our WLS 4.5.1 hangs even
    at a
    mere load of 20 users. We are running on a Solaris machine. Database:Oracle
    8.1.5, running on the same machine. Usingoracle.jdbc.driver.OracleDriver as
    the JDBC driver, and using JTS as the transaction manager.
    When we did a thread dump (complete lis at the end of this post) and
    basically we are seeing a bunch of our entity beans in a "locked" state.A
    common pattern we see in the thread dumps is that

    method>(ERSSystemConfigurationBeanEOImpl.java:1539)
    [6] com.nps.ers.ejb.awardnomination.<Our entity bean>.<some method>
    After more thorough studying of EJB transactions, we changed theisolation
    level of all our beans from TRANSACTION_SERIALIZED to
    TRANSACTION_READ_COMMITTED and made sure all our beans say TX_REQUIREDfor
    their transactionAttribue. Still, this problem persists.
    The basic scenario we are load testing is that of multiple users logging
    into the system and trying to access a particular user's record, andright
    now, this is causing deadlocks at 20 users.
    What we fail to understand is that --
    (a) even if a method is attempting a read-only access to the data, whywould
    it try to obtain a lock? or why would it matter that the data is locked?
    Some of the locks we are seeing are actually on a bean that is used for
    read-only purposes.
    (b) if 2 or more processes are trying to access the same record, basedon
    whichever process got their first, shouldn't one succeed, and the othergo
    into a 'waiting' state?
    We have also opened this issue with weblogic support, and the responseso
    far has been that there "may" be a bug in weblogic 4.5.1 itself that's
    causing it, and they need to look into it further. Other similar postsin
    the newsgroup haven't been resolved either -- hence this general pleafor
    help. Please advise if you've any suggestions. Thanks

  • User is thrown from the Application under Cluster stress test

    Hi All,
    i have ADF/ADF faces application running on WLS 10.3.5.0 Cluster Environment (with 2 nodes).
    I'm running application using in memory Session replication.
    The problem which i have is that under the stress test (about 10-20 users) sometimes user suddenly is presented with Login Screen (more rare with session expired message) ! This also can happens immediately after user login .
    That happens randomly on different part of the System. In more of the cases user is thrown independently from other users but
    sometimes all the users are thrown simultaniously.
    When the System is tested with only one user this effect appears very rare.
    What i have done is to enable Cluster and Replication debugging to see if there some errors within Http Session Replication. However there isn't any errors appeared. From the application part everything seems fine.
    I suspect that the proxy could cause a problem (by forwarding the request to secondary instead of primary server). Currenltly i'm using HttpClusterSerlvet installed by default from WebLogic Configurator on dedicated Managed Server.
    Can somebody give any advice with this ?
    Thanks in advance,
    Krasimir

    Krashmir,
    Did you find any solution for this problem. I am also facing the similar issue.
    Thanks,
    Ram

  • SQL connection errors when stress testing mobile service: SQL failure after 3 attempts

    I have created a Mobile Service (node.js), which has been running for a few months with 50-100k api calls per day with no issues.
    The usage of the service will be scaled up soon, and it will receive much higher traffic, so I am running stress tests (on a staging deployment of the same service).
    The api in question queries data from the sql database that is attached to the mobile service, but caches the resulting data in a redis database for 5 minutes, so each call with identical parameters will not access the SQL database, just the redis cache.
    My first test never has any problems:
    Run a single api calls as fast as possible using the program wrk (https://github.com/wg/wrk). This test never has a problem, and I have run it an hour continuously with a sustained rate of 200 req/s and very few timeout errors.
    The second test always causes problems:
    I created a list of 5 different api calls to the same service (same endpoint, but different parameters), and I run those randomly interweaved as fast as possible. I use the program locust (http://locust.io) for this, spawing 10.000 clients at a rate of 500
    per second. For the first few seconds everything goes ok, but then connections start failing massively.
    I get mostly:
    Error: SQL failure after 3 attempts. Error: [Microsoft][SQL Server Native Client 10.0]TCP Provider: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected
    host has failed to respond.
     (SqlState: 08001, Code: 10060)
    And I see this in the http response:
    ConnectionError(ProtocolError('Connection aborted.', gaierror(8, 'nodename nor servname provided, or not known')),)
    The strange thing is that since I am running the same five calls repeatedly, only the very first of each call will actually access the sql database, every subsequent call will just return data directly from redis, and not try to access the sql database at
    all.
    In the azure console for the sql database in question, I see 1860 successful connections and 11 failed connections, which does not explain the massive failure rate I am seeing.

    Thanks for sharing your tips on this forum, as it will be useful for other users, that run into this issue.
    Feedback like this will also help us improve error reporting in the next release, as missing class files in the packaged application is a common issue when developers are moving from the embeded oc4j instance packaged with JDewveloper to standalone instances.

  • Stress test Sharepoint 2013 portal. How and what do You use?

    Hi!
    I'm using example from here http://msdn.microsoft.com/en-us/library/jj710162.aspx
    It creates record in SP task list. I can loop it to create several records. But how can I simulate
    several users?
    Or what in common sense do You use to stress test sharepoint? Any links or better there is a book?
    Best regards,

    >>You can use Visual Studio to create performance and stress testing projects.
    Yes I know that I can use VS, it's in the link of my first post.
    >>Check out my articles at:
    Margriet, thank You very much! I see that You analyzed more than a hundred of tools and dived very deep into this question! Thank You for
    the tool, it works for me!
    1) But what You use to monitor server behavior, do You use Resource monitor? By example I can see some network and cpu activity during test, but how can I analyze this data..
    or I'd use some video-capture tools(like 'camtasia studio'), record this system monitor and then analyze?
    2) I understand correctly, that this tool covers "WFE test", mostly IIS, like pages generation; SQL database should be tested by other methods.
    p.s.:Sorry for bad english)
    upd.: added all Your counters, the picture looks impressive :-D

  • Stress test Forms 9i

    Hi,
    I would like to perform an stress test on 9i Forms application and I have two approaches:
    1) Buy a tool.
    2) Build a client that performs petitions.
    The first approach doesn't seem to work because I only know 1 provider which haven't answered to my request. Anybody knows tools like what I need?
    For the second approach I would like to know:
    * Is there any forms API which I could use to build my client? Probably there must be one because I only need the communication classes of the forms's applet and Interact with them.
    Thanks. Miquel.

    YES, you can do this by recording http traffic. This is exactly what you do with LoadRunner from Mercury Interactive. The recorder have a correlation tool wich take care of the dynamic part of the URL and modifies the generated script for you by inserting variables into the programmable script. I have used LoadRunner succesfully to stress test our Internet based Forms 9.0.2 application (http://www.syx.com). We did not dare to go alive without a fullscale test. LoadRunner did the job, and we found several scalability problems realted to the OS and AOS configuration. With LoadRunner you can setup several load generating servers - world wide if you like - each can simulate tousands of clients. Everthing can be orcestered from a mangament console where can can fire up clients with different scripts to form various load patters. E.g. I used one script wich logged users in, waited, and logged out. Other scripts instanciated and closed new forms all the time. E.g. by combining these scripts I could see how the server scaled when I had 200 passive users in the system, 10 users logging in every 10 seconds, 10 users logging out every 10th sec, and 50 users continuosly instanciating and closing new forms wich actually where running the most demanding DB query in our system.

  • Stress Test question

    Hi,
    i've perform a stress test of a database in 2 configuration :
    1) Single instance 11.2 with 8gb Sga e 4gb Pga on Linux, 6core with instance caging =4, resource_manager=defaut_plan
    2) 2 Nodes Rac 11.2 with 8gb Sga e 4gb Pga in both nodes on Linux, 32core with instance caging =4, resource_manager=defaut_plan
    I've used Swingbench and the transaction per minute are equal, Avg transaction per s in rac are Greater then single instance (4ms vs 40ms).
    I know that rac is not for high performance.
    My question is: is rac config best than single instance and if yes what is the %?
    Thank you

    Hi SBHV,
    As far as I know, if you choose to test Audio Conferencing, it will also simulate Video conferencing.
    And the Key Health Indicators in Lync Server 2013 for your reference.

  • Stress Test using em console in 11g results in lesser number of instances

    Hi All,
    We are doing Stress/Load testing using em console in SOA Suite 11g. The problem we are encountering is, em fails to create as many instances as it should. Under "Additional Test Options", we check the "Enable Stress Test" checkbox and give different values for following parameters:
    Concurrent Threads     50
    Loops per Thread     20
    Delay in Milliseconds     1000
    But instead of creating 1000 instances of this composite, em console create only 998 and fails to create 2 instances without giving any error in console logs or server logs.
    Similarly, with below setting:
    Concurrent Threads     50
    Loops per Thread     40
    Delay in Milliseconds     1000
    Instead of creating 2000 instances it creates only 1991 and 9 instances fail without any error. Is this a known bug or we are missing something here? Any pointers will be helpful.
    Thanks,
    Akash

    In case you have multiple instances running, whereas any instance has an unique value started as correlation, when the engine receives the messages for the intermediate receive operation it will be routed without problems to the right instance. In this case, it is not a problem if the engine creates a new composite instance for the intermediate messages.
    We have this situation in Production without any problem.
    Anyway should be simple to simulate the same situation in your development environment to make sure it works well in your scenario.
