Help! Mysterious exception during load tests (call on a cache item)

Under load, we are witnessing the track below: DistributedCache$ BinaryMap.onMissingStorage is thrown an exception.

We do:
o = nc.invoke (cacheKey, proc);

If the key exists in the cache (it's a control block that is reused over and over).

It started just show up under load.

Anyone know what this means?

Configuration: 2 storage nodes, 15 client and JMX nodes, each node storage on its own machines, other nodes distributed on 4 machines.

These initiated very long communication delays probably death detection logic. There are a few possibilities for the delay. GC is a likely scenario and would need more logging to confirm information. Often the pile is not big enough and JVM spends time trying to free the memory. This is a link to a control area which includes a section on the JVM tuning including GC Monitoring & Performance Tuning

Increase can help and is documented as follows:

The maximum time one or more nodes can be insensitive before be removed from the cluster is configured using the
subitem of and by default a minute for production configurations. This increases
value will allow the cluster to wait longer for connectivity to return. The downside to increase this value, it can also take more time to handle the case where a single node has lost connectivity.

There is also an entry in the forum with a nearly identical stack dump, the only exception is the use of 3.5 of coherence which introduced the function of guardian of coherence.

Re: Command fails only under high load and cache APP store.

In this case, the APP store is reported as a bottleneck and reducing the and the increase has helped reduce this bottleneck.

  • With the help of functional test for load testing scripts

    Hey,.
    I'm new to this tool. Right now, I use a version 9.2 of OATS. I created a few functional scripts for Oracle E - business applications using openscript. Can I use the same scripts for my load tests. If so, how would I be able to do? When I created a load of scripts using openscript, they appear in BTA. But my functonal scripts do not appear under 'select scripts' upward section OLT.

    You will need create scripts for load tests. Functional scripts cannot be used BTA. The exceptions to this rule would be the "General" components (Code of Java Script & Web Services), which can also be used in BTA.

    for example, instead of "Testing - Oracle EBS/functional forms.
    Select "Load Testing (Protocol Automation) - Oracle EBS/forms.

    Once you get in tests that you will realize that you want to create very specific scripts and do not want to try to re-use of functional scripts to load. I know that many of these tools are "sold" to the fact that functional scripts can be reused for the load, but when it comes down to it, you'll want to design your scripts load separately anyway!

  • Why the total time required for the test sequence is different during the test runs

    Hello

    -J' have different test resources to test our product which includes engines and the NOR-Box (6351).

    -Number of test files in sequence that are called during the test (ca. 20)

    -The problem is that when I run these test sequence files separate (say only 3 out of 20), total time by these tests are t1, t2 and t3, but when - I left all 20 tests to run without jumping all the time needed by the 3 tests above is t1 + 60 s, t2 + 80 s and t3 + 50sec. Why it is so and how can I avoid this problem.

    -The tests are motors to move, take samples or box then save them on my computer after testing the limits. Since they are time critical, when I do all the running tests in a test go a lot do not PASS. I can't run them separately because it takes more time, more interference by user and also more than one report that is not desired.

    -J' tried unloading after execution steps, but it did not help.

    Kind regards

    RB

    This probably depends on that made your sequence. Have you tried shrink where extra time is being spent? You can time how long different parts of your sequence are following the steps of the expression as follows:

    Locals.StartTime = Seconds()

    Locals.ElapsedTime = Seconds() - Locals.starttime

    You can also watch time module in your reports. There is nothing specific on TestStand that should cause some sort of slow down like this. I recommend trying to figure out where the extra time is being spent. I suspect once you do, the cause will become obvious.

  • Phone dials a number at random during an ongoing call

    My phone and my wife's phone has been randomly component another number during an active call. This causes the current call to give up without warning.

    I thought it was my accidental mistake until it happened to him, then it is true again and again on my phone.

    You should try an app like Tools of Droid of Tedd. It locks the screen while you are on a call, which will prevent the face dials. It locks the screen and prevents any entry through the screen while you are on a call. I'm not saying it's happening for sure, but it could be. This could be a good test for it. If the problem goes away when you use tools of Tedd Droid that I would say that what's happening is you're face composition.

    There's another app on the market that will do the same thing, but I don't remember the name of any other. I hope this helps.

  • See load test: ways to script for applications commands?

    Hello

    I'm designing a simple tool for an environment of view and so far its goes pretty well load test.  With the help of command line arguments and some Powershell, I am capable of recursion through a list of users and connect multiple sessions on a display server and open office and a few RDS App sessions.  My question is: is there a built-in way to pass a script in the command line arguments run certain commands on this computer to office or RDS App session?  Nothing crazy, just type in Notepad, open a few programs, save a doc or two--the usual stuff to generate regular workloads.

    I know that VMware and third party companies have tools for this, but they don't specifically meet my needs without extensive configuration and a lot of hooks in our systems.  I'm trying to keep the footprint of this test as small as possible, so a simple Powershell script is how I want to move forward.  I guess that Powershell has a method to do this, but I'm not guru script nor it is a PS forum, so I was hoping there was something that already exists when I call the view connection that I could use.

    Any help is appreciated, thanks in advance!

    I can not completely solve your problem, but it can be a little simpler.

    Q. for the "is there a built-in way to pass a script in the command line arguments run certain commands on this computer to office or RDS App session?

    A. No, but you can use strategies Group (GPO) that can be activated when his connection to run a script.

  • Question encountered in Oracle load testing

    Hello

    We created a sample script using Oracle Script and trying to read for multi users with Oracle load test open. to simulate the real effects of the users, we had used the database for this scenario. All scripts and csv file is placed in the storage folder.
    During configuration of database construction scenari otab, we face as a result of warning message "cannot find the database file (rest = new repository;. file = Bank of data/null)

    Please help how to solve this error.

    Kind regards
    Mahesh

    Hello

    This means that OLT cannot locate the data bank when you try to read the script. When you have added the database for the script or the script you were asked if you want to refer to the data from the repository Bank. My guess is that you probably chose repository, so try to choose the script instead.

    Hello

    When you load test OpenScript will change your browsers proxy to point to localhost 7777 as is the port that openscript internal proxy uses to save the navigations, can you check if when the parameters of proxy registration with FF is FF changed?

    If this isn't the case, you can try to manually change them to point to localhost 7777 you will find the settings in the Options -> Advanced -> network -> settings.

    If the proxy is already set, please check that there is nothing on the no proxy for: box

    You can right click on the section to initialize your script and then:

    Add-> other-> HTTP-> authentication.

    You need 3 parameters:

    A - http://someurl - url that will authenticate any url that contains the http://someurl string for example http://someurl.com/index.html
    A password
    A user

    The following code should be added in your script:

    Well I can't yet reproduce your error, even with the resolver that you gave. Nothing in your resolver is clearly wrong, although it seems strange that you use tntManager to create the stream buffer instead of the XmlManager spent by the funtion. Try calling

    return xmlManager.createMemBufInputStream(null, 0, false);
    

    Instead of

    return tntManager.createMemBufInputStream(null, 0, false);

    Or there is another option to use variables separated and shared at the same time for 2 parallel Sockets (ParallelModel.seq).
