Multi step program

Dear all,
As a newbe here i would like to know if somebody reconizes this problem.
I think i am looking for the obvious, though i cann't find it. In labview i would like to do the following:
make  a screen in which a user can make a automated program to run his reactor overnight.
the program needs to be time controlled but also settings controlled.
it is going to be for the control of a reactor which uses gasses and temperature
and certai ntime the temperature should change and or the gas flow.
does anybody has a idea to solve this problem?

Well said, Gabi1.
Your first step should be the design.  Describe how you want it to work, and describe any daily routine that can be translated into a profile.  You can write the software to load a given profile which means flexibility for the future.. 
All this takes place in the upfront design process.  Don't rush into coding before it is clear what you want to do and how..

    Spotlight lists items and shows preview images.  BUT what about showing the path/location address of an item in my computer.
    Especially important if I've put the item in the wrong folder and what to locate it without multi-steps. iMac OS X 10.5 was more useful.
    Old OSX Spotlight function automatically displayed path/location within the machine:  e.g. desktop/folder/sub-folder/item.
    Can I make Spotlight show the path?

    Press option-command and the path is displayed at the bottom of the little preview window.  Press command-return and the enclosing folder opens. 

  • Running a Java Multi Thread Program in database

    I have created a multi threaded program in Java and it runs successfully from the command prompt. I want to create a DBMS Job which will wake up at regular intervals and runs the java program(Java stored procedure). Is this possible in 9.2/10G ?? If Yes, will there be any impact on the DB performance/increase memory etc.,
    The database (9.2...) resides on a RH 2.3 AS box.
    Any ideas...
    Thanks,
    Purush

    Purush,
    Java stored procedures cannot be multi-threaded. Well, they can, but the threads will not run in parallel. You may be able to find some more information in the Oracle documentation, which is available from:

    Good Luck,

    Many biological databases can be queried directly via the Structure Query Language.SQL is at the heart of biological databases.Oracle Data Miner load data from flat files in the database.we would create a numeric ID for the genes while loading the data and remove some columns and rows from the data, it is better to load the data directly with SQL Loader.

  • Multi threaded programming

    I am quite new to multi threaded programming.
    The problem I am facing in my code is as follows:
    I can instantiate 1-10 threads from my controller class. For example if my controller class generates 10 threads, 5 threads
    finish the task they are assigned to do(i.e send SMS and Update the Database) and the other 5 threads eventhough send SMS but
    get stuck when they are supposed to update the Database (this is inferred from the logs).
    Due to this problem my controller class remains in a wait state as I am using the join() method and some of the threads never
    join.
    Another interesting observation is that it always happens that the thread numbered 0-5 always get stuck at the exact point
    where database has to be updated and thread number 6-10 complete their task. Same is the case when i instantiate 2 threads, i
    thread completes its task and another thread gets stuck, again at the same point.
    I am using Connection Pooling to connect to the database.
    I am sure that the problem is with the query
    int j=dbObject.execute_pst("UPDATE table SET flag='true' WHERE message IN("+trueFlag+")",con);
    where true flag is a comma seperated string containing some ID's.
    What i cannot understand is why some of the threads (almost 50% of them), work fine with this query and the others get stuck
    (i.e. just wait at this query during runtime)

    The problem must lie in the connection, as the SQL statement is to basic to cause an endless loop inside the DBMS. If you are in doubt, try the setMaxRows() method of the Statement interface, I'm using Sybase and it also limits the number of rows processed in update and delete statements (which I'm pretty sure is buggy, but you can still try it).
    Which DBMS are you using by the way?

  • Best way to create a multi-step validation process

    I am writing a multi step validation process and I was wondering what is the best method to have it operate on the value.  What I have:
    As a custom validation script, in that order:
    1- Calls a function that looks if the value is part of a particular array
    2- Calls a function that regroup some tests
         2a- function test1()
         2b- function test2()
         2c- function test3()
         2d- function test4()
    What I have now is every test ends as 'event.rc = false' when they fail which is what I need but I also need to stop the entire validation process.  As an example, if the value fails test2() and gets a "you have failed test 2" alert, I don't want to call test3() and test4() since it is already decided that it failed one of the tests.  I could return a boolean that triggers (or not) the next test() but isn't there a simple way to just say
    event.rc = false;
    "STOP EVERYTHING";
    I have the assumption that break; will only stop the test() but still move on to the next test().  Maybe I can return break; so it will be called from the 'master function'?   Is that even possible?

    Create another function and call it from the validation script, something like:
    function validate_field() {
        // Call the first validation routine
        test0();
        // Abort if first validation fails
        if (!event.rc) return;
        // Call the second validation routine
        test1();
        // Abort if second validation fails
        if (!event.rc) return;
        // Repeat for any other tests

  • Multi-step Purchase Order Release Workflow

    Hello everyone,
    I'm about to pull my hair out over here with this workflow. 
    -We're using ECC6
    -We've configured multi-step release strategies for some of our PO's. 
    -I've linked the RELEASESTEPCREATED event from BUS2012 to WS20000075.
    -The workflow is failing at agent determination, prior to creation of the workitem.
    -It appears that the Release Strategy (FRGSX) is being passed in the RELEASE CODE parameter of the workflow container, rather than the actual Release Code (FRGCO), causing the agent determination to fail.
    -Both the rule and the entire workflow work flawlessly when executed manually using the Release Code (FRGCO).
    What's going on here? Can WS20000075 handle multi-step approvals out of the box?  I've read conflicting opinions all over the internet, and still haven't been able to find a straight answer. Does anyone have any suggestions for a fix?
    I'm very new to Workflow, so be gentle.
    Thanks,

    Hi Sue!
    Thanks for chiming in.  It looks as if TS20000166 is bound to the release step, and while there was one previous version, it appears to be a duplicate of the original.
    Below is some additional error info from the step history:
    AC20000027 - Element REQUISITION is not available in the container
    EVALUATE_AGENT_VIA_RULE - Error in resolution of rule 'AC20000027' for step '0000000093'
    CREATE_VIA_WFM - Agent determination for step '0000000093' failed
    CREATE_WIM_HANDLE - Error when creating a work item
    CREATE - Error when creating a component of type 'Step'
    PROCESS_NODE - Error when processing node '0000000093' (ParForEach index 000000)
    Exception occurred - Error when starting work item 000000451141
    Also, if I examine the contents of the container, the ReleaseCode parameter contains the FRGSX value (7D), rather than the FRGCO value (D7), despite the fact that the definition for the expression specifies T16FC-FRGCO.
    I've tried debugging the ME_REL_GET_RESPONSIBLE FM from the rule, but my breakpoint doesn't hit when I'm creating PO's, only if I start the workflow manually.
    Might I have mis-diagnosed my problem?
    Thanks for your help,

  • Entity validation behavior in multi-step process

    I'm using jdev 11g with ADF BC and I want to create a multi-step process with a train to split a long form into multiple views. The fields on the form are based on a entity object that was created from a database table. Most of the fields are mandatory. The problem is when I want to navigate from page to page the mandatory validation rules are triggered for all fields. So far, the only way to go around this is to delete all mandatory contraint from the entity object and set the fields on the form as required. Is there a way to differ the validation on the entity object when a commit is done or trigger only the rules for the fields on the current page?
    Thanks.

    Hi,
    have a lok at the PageDef file of the pages. There is a skipValidation property that you can use to declaratively suppress validation. Try setting this property to true fro all but the last page in the process. Using this property you don't ned to change the constraints in the model

  • My new Nano has no Fitness "steps" program.

    How can I get the software for the "steps" portion of the Fitness program?

    There is no "walk" option in the Fitness program on my new Nano.  All I have is "Pedometer" and "History".
    Should I take it back to the store because the "walk" or "steps" program is missing?  The 6th Generation Users Manual shows this as part of the program, so I would very much like to see it on MY Nano.

  • Multi-step replenishment and ECC 5 for Retail

    I have a few questions regarding this topic as we are trying to get a handle on this functionality. So, if any of these questions is applicable to you I would appreciate an answer:
    1. Are any of you out there running the Mult-step Replenishment functionality SPECIFICALLY ON ECC 5.0?
    1.a) as a follow on to this question, are you running the Retail Industry solution?
    2. For those of you running this on ECC 6, did you first implement this on ECC 5 (or older)?
    2.a) as a follow on to this question, did you experience problems or require changes to your solution when you upgraded to ECC 6?
    And for the consultants out there:
    3. Do you or do you know of someone who has direct experience with implementing this functionality on ECC 5 for Retail?
    Thanks,

    But also i wanted to know how exactly IS-Retail will help us in comparision to ECC 5.0.
    I mean i want to know what excatly will be the added adv. of it over ECC.
    (bcoz browsing through sites / forums is not giving me much of a info.)
    ALso if i change my existing ECC system to Retail what will be the implications on the current envioroment.
    Can i get a Link / PPT/ article relating to this.

  • How can I automate the multi-step process of looking up a caller's contact details when a telephone call comes in with caller ID?

    How can I automate the multi-step process of looking up a caller's contact details when a telephone call comes in with caller ID. I want to be able to see more than just the first & last name when a client calls me. I would like the caller ID to pull up the same information that shows up when you search for and find a contact name and then click on the right arrow.
    My workaround is to force/enter both the last name and the address in the last name field since then the address will show up.
    The only computerized way to look up this additional information is to put the client on hold, memorize the first and last name and correctly enter it in the search field of the contact database and hopefully find it before the client gets tired of waiting.
    Note that I go to about 48 small jobs per week. So far I have about 9,000 contacts. It's easy to make a mistake and have the client wondering what I'm doing and what's taking so long.
    The second workaround is to use paper and pencil and ask the client for name, address, cross street and phone number again, repeating what I did some time previously.
    Please help meautomate this process.

    You don't have to put anyone on hold. When the call comes in, tap the Home button, then tap contacts, go to the contact. Tap Home button when finished, tap the top banner to return to the call screen.
