Graph not initialized: is it possible?

Is it possible to have a graph without initialization? I mean I would like that it could keep the plots from the previous run of the vi, so that at the following run the new plots could be superimposed on top of the old ones without the old being cleared.

You are not very specific here, but you are probably looking for a chart. This assumes that the data is spaced equally in time.
Another possibility would be the xy graph frmo the express palette. You can configure it to retain data between calls.
In the most general case you can build up your data in a shift register.

  • Java.lang.IllegalStateException: Cipher not initialized during loadtest

    Hi All,
    Below is my code :
    static Cipher pbeCipher;
         byte[] encbytes = hexToByte( encrypted );
         pbeCipher.init( javax.crypto.Cipher.DECRYPT_MODE, pbeKey, pbeParamSpec );
    byte[] decbytes ;
    synchronized (pbeCipher) {
         decbytes = pbeCipher.doFinal( encbytes );
              return new String( decbytes );
    I got the below exception when we are actually performing the load tests where in 4000 hits are made on the code in 1 min.
    java.lang.IllegalStateException: Cipher not initialized
    at javax.crypto.Cipher.c(Unknown Source)
    at javax.crypto.Cipher.doFinal(Unknown Source)
    My doubt here is : Is it occuring becuase of synchronizing issue? As shown in the code above i had synchronized the doFinal call. Still the exceptions are occuring. These are randomly coming say 1 out of 500 hits.
    Please suggest me a solution on how to fix this. We are using PBEWithMD5AndDES encryption mechanism in this case.
    Solution for this would help me a lot in terms of fixing it...
    Thanks in Advance......

    Cipher is not thread safe so that is almost certainly your problem. Your synchronisation does not include the init() method so it is possible that the instance is being initialised in one thread and used for decryption in a different thread.
    My approach is to create a pool of Cipher instances and then get an instance from the pool, use it and then put it back in the pool.
    P.S. DES is now considered deprecated in favour of AES. PBE is a poor man's approach since the chances are the password has far less entropy than the key size so will be much weaker than that implied by the algorithm being used. PBE is normally used for securing a user's data so in a Web based application it normally does not make sense to use PBE.

  • Can't receive headers from JMS Adapter - "Variable is not initialized"???

    I'm using JDeveloper Studio 10.1.3.4.0.4270 to try to build a BPEL process that is initiated by a JMS Adapter. I want this process to access the headers of the incoming message. Despite what Adapter Technical Note #005 says, JDeveloper says I can't do it! Despite the fact that the Receive activity is set up to store the header to a variable, JDeveloper says the variable is not initialized when I try to access it. (At least this is consistent with BPEL Process Manager's behavior -- the runtime also says it's not initialized.) In the following simple code, it looks initialized to me. What am I missing? Thanks.

    Hi,
    Your code looks correct to me. However, you should name your durable subscriber: topicSession.createDurableSubscriber(topic, "myDurableSubscriber");
    Then it should be possible to use your JMS provider administration API to check that your durable subscriber is registered with your topic. Once the durable subscriber is registered it will start receiving message.
    To double check that your code is correct, you should test your code with another provide.
    Hope this helps

  • Rv215w not initiating vpn connection

    Hi,
    Can someone tell me why rv215w is not initiating the site to site vpn connection ?
    I configured the connection with the ASA5505 and everything is working
    beautifuly if the connection is initiated from the remote site (eg. ping from the remote network),
    but if tunnel is disconnected and I want to establish connection from the
    network behind the RV215 then it is not possible.
    RV215 is not able to initiate the ipsec connection ?
    Regards
    Michal Witkowski

    Dear Michal,
    Thank you for reaching the Small Business Support Community.
    I would first suggest you to make sure "Perfect Forward Secrecy" setting is disable on the ASA and "PSF Key group" uncheck under the "Advanced VPN settings>Auto Policy Parameters" on the RV215.  If already disabled on both sides and the problem persists, I then suggest you to set the "VPN Advanced settings>Exchange Mode" to "Main" and not "Aggressive" on both sides.  Uncheck the "Dead Peer Detection" if the problem persists.  If no difference please screenshot and send the "Advanced VPN Setup" settings for us to check them out. 
    Make sure you run the latest firmware release version v1.1.0.5 on the RV215;
    http://software.cisco.com/download/release.html?mdfid=284436489&flowid=37822&softwareid=282487380&release=1.1.0.5&relind=AVAILABLE&rellifecycle=&reltype=latest
    Just in case you may need it, below is a link for the admin guide where on chapter 5 describes the VPN parameters I mentioned;
    http://www.cisco.com/en/US/docs/routers/csbr/rv215w/administration/guide/78-20779.pdf
    I'll be looking forward to your reply.

    Why is that? I'm new to Java..Maybe because the Class you are trying to run is not an applet? Possibly, but the OP posted the Account class, whereas the Start class has not yet been revealed. That is one of the reasons I suggested an SSCCE.

  • The workflow could not update the item, possibly because one or more columns for the item require a different type of information. Outcome: Unknown Error

    Received this error (The workflow could not update the item, possibly because one or more columns for the item require a different type of information.) recently on a workflow that was
    working fine and no changes were made to the workflow.
    I have tried a few suggestions, i.e. adding a pause before any ‘Update’ action (which didn’t help because the workflow past this action without incident); checked the data type being written
    to the fields (the correct data types are being written); and we even checked the list schema to ensure the list names and the internal names are aligned (they
    are), but we still cannot figure out why the workflow is still throwing this error.
    We located the area within the workflow step where it is failing and we inserted a logging action to determine if the workflow would execute the logging action but it did not, but wrote the same error message.
    The workflow is a Reusable Approval workflow designed in SharePoint Designer 2010 and attached to a content type. 
    The form associated with the list was modified in InfoPath 2010. 
    Approvers would provide their approval in the InfoPath form which is then read by the workflow.
    Side note - items created after the workflow throws this Unknown Error some seem to be working fine. 
    We have deleted the item in question and re-added it with no effect. 
    Based on what we were able to determine there don’t seem to be any consistency with how this issue is behaving.
    Any suggestions on how to further investigate this issue in order to find the root cause would be greatly appreciated?
    Cheers

    Hi,
    I understand that the reusable workflow doesn’t work properly now. Have you tried to remove the Update list item action to see whether the workflow can run without issue?
    If the workflow runs perfectly when the Update list item action is removed, then you need to check whether there are errors in the update action. Check whether the values have been changed.
    Thanks,

    Thanks for the quick response Nikhil.
    Our SPF 2010 server is relatively small to many setups I am sure. The list with the issue only has 4456 items and there are a few associated lists, eg lookups, Tasks, etc see below for count.
    Site Lists
    Engagements = 4456 (Errors on this list, primary list for activity)
    Tasks = 7711  (All workflow tasks from all site lists)
    Clients = 4396  (Lookup from Engagements, Tslips, etc)
    Workflow History = 584930 (I periodically run a cleanup on this and try to keep it under 400k)
    Tslips = 3522 (Engagements list can create items here, but overall not much interaction between lists)
    A few other lists that are used by workflows to lookup associations that are fairly static and under 50 items, eg "Parters Admin" used to lookup a partners executive admin to assign a task.

  • What's the difference between a not-initialed object and a null object

    hi guys, i wanna know the difference between a not-initialed object and a null object.
    for eg.
    Car c1;
    Car c2 = null;after the 2 lines , 2 Car obj-referance have been created, but no Car obj.
    1.so c2 is not refering to any object, so where do we put the null?in the heap?
    2.as no c2 is not refering to any object, what's the difference between c2 and c1?
    3.and where we store the difference-information?in the heap?

    For local variables you can't have "Car c1;" the compiler will complain.That's not true. It will only complain if you try to use it without initializing it.
    You can have (never used, so compiler doesn't care):
    public void doSomething()
       Car c1;
       System.out.println("Hello");
    }or you can have (definitely initialized, so doesn't have to be initialized where declared):
    public void doSomething(boolean goldClubMember)
       Car c1;
       if (goldClubMember)
           c1 = new Car("Lexus");
       else
           c1 = new Car("Kia");
       System.out.println("You can rent a " + c1.getMake());

  • Error in communication channel " not initialized"

    Hi All,
           I'm working in FIle to mail scenario. In this scenario whenever i upload a text file to the R/3 application server. that file should be sent (as a attachment with a mail) to any email id. I did all the required configuration in IR. but i'm verymuch confused in ID configuration. I have created both sender and receiver communication channel in the same business system which refers a sender (R/3) System.sender communication channel is working fine. but when i activate the receiver communication channel it shows an error "not initialized".
    So kindly let me know,
    1. Should i use business system for my receiver end?,If so how do i create it?
    2. is receiver agreement, receiver determination, interface mapping necessary? If so, how do i configure it? because i'm not using any recever service since i'm sending mail to my mail box.
    note:
    It would be very helpful if u refer any link to find out the recever determination and interface determination configuration for this type of scenario.
    Thanks & Regards,

    Hi,
    Depending on your XI/PI version, apply one of the notes below to correct import the ESR content:
    PI 7.1X:
    #1152640 - SAP NetWeaver 7.1 including EHP 1: Importing ESR content
    XI 7.0:
    #836200 - SAP NetWeaver 7.0: Importing Process Integration Content
    XI 3.0:
    #705541 - XI 3.0 (SP1 and higher): Importing XI Content
    Also, check if the service for the adapters are running. Restart the J2EE Engine.
    If not solved, you may try redeploying the adapter's driver.

    hi prasad
    There are 2 jar files that may be missing from your SQL JDBC driver --> msbase.jar and msutil.jar, I think once you add these to the driver it might work.
    also check  the driver string for the SQL  driver 2 parameters
    i.e 'com.microsoft.jdbc.sqlserver.SQLServerDriver' now becomes
    'com.microsoft.sqlserver.jdbc.SQLServerDriver'
    This will solve your problem
