Multi-threading parallel processing of stored procedures

  I use LView 8.6.1 and I am very new to LabView.  I have two functions completely aysnchronous in a physical machine.  The first function looks at temperatures of a couple of Thermistors and runs a PID controller to maintain a setpoint.  The second function is running an engine step by step to perform a mixing function has nothing to do with the function of the temperature. Both functions require calls to a set of 3 rd-party of vi, and these vi is integrated in the two parallel loops in a while loop, shown external attachment (generic version due to confidentiality issues). .

  When the same VI is used in both loops, I have them made re-entrant.  I added at least 100 mS wait States to each loop displayed to allow the switching of the CPU.  I have 2 nuclei and the max machine reports 5% CPU usage.  I wired the device configuration and management errors in the parallel between the two loops to avoid the unintentional flow of data series.

  I spent hours and hours searching through posts on this forum and others to try to determine how * completely * asynchronous use these two functions and avoiding of upsetting someone, but no matter how I do it, it seems that some level of dependency is created between the loops.  This can be seen because the loop faster (temperature) ends correctly, but then is forced to wait until the iteration of the slower loop to a conclusion.  I got it to a point where the dependence is tolerable (at one point one of the loops has not yet run!, the other dominated the treatment completely) but I would prefer a real independence because of timing related to the façade being insufficient, how it currently works.  When the loops run in the first place, they do so at independent rates just as I would like.  So independent treatment is possible.  That's when a loop ends, he must wait for each other to end before starting.  I tried loops clocked with a dedicated CPU core and that has not changed anything.  The outer while loop doesn't seem to be the culprit.

  Question: it seems that no matter what, some level of control of the running serially is inherent in a multi-threaded data process.  Queues, notifiers, semaphores, States, engines machines of the action, event - all seem to link a process to another.  Is there a truly independently to address the process completely separated in LabView so that each runs at the rate defined by respective waiting functions and have nothing to do with each other otherwise?

  Thank you.

  You can run the initialization code before starting all parallel loops using the wire of the error as a means of controlling the flow of execution.  See below:

  

• FDM batch Loader - error 5: Invalid procedure or augument - parallel process call

  -Lot controls in the FDM workbench are as follows:

  Batch type - Standard

  Level of process - import

  Process method - series (I tried both serial and Parallel)

  Filename delimiter - _ (underscore stroke)

  -Batch file names follow the instructions in the Administrator's guide - < version > _ < location > _ < category > _ < period > _RR.txt (e.g. 1_TESTING_ACTUAL_Q1 - 2012_RR.txt)

  -J' also checked and the FDM data in the shared drive folder comes with a complete access control (read/write).

  -Batch files have been moved to another file sibiling as OpenBatch with a unique name, but the data could not import into the locations.

  -J' also created and launched the script from a web client and the batch workbench.

  I look at what has gone wrong... I want to ask you expert advice. Any help would be appreciated, thanks in advance!

  Hi all

  Thanks a lot for all your response. This issue is resolved as soon as possible and I want to just share what we have done and close this post.

  By my team, the FDM Task Manager has not been configured properly for the loader commands to run. Therefore,.

  1. to configure the FDM Task Manager

  For the file name, such as we would use the description for the period (e.g. T1 - 2012), so

  2. we need to enable the setting "Allows a description custom period." (in the Admin--> Configuration); and

  3. put the spaces between Q1-2012 in file naming for batch loading (for example, we cannot put ___Q1 2012.txt, must be ___Q1 - 2012.txt)

  The batch charger works fine now.

• Apex. Submit-&gt; process to run one of the two stored procedures on page

  version: 4.2.5

  page one region: form on the stored procedure

  region of page two: form on the stored procedure

  The region button 'submit' for the region page 2:

  ACTION: Redirect URL

  Run Validations: YES

  Target URL: javascript:apex.submit ('CALL_MY_PROC');

  'Treatments' execute the stored procedure

  Point process: submit now - after calculations and Validations

  Enforcement process: once a Page visit (by default)

  ...

  Conditions

  When you press the button:-no Condition button

  Condition type: request = Expression 1

  Expression 1: REQUEST = CALL_MY_PROC

  The expected behavior is to call the stored procedure in the region on two page without invoking the other stored procedure.  Separation of concerns is desired, this button sends the form this proc, this button argues that form to this proc.  Nor should call each other, so to speak.

  The stored procedure is not called when I click 'Submit' (button from region to region page two).  How can I solve this?

  Thanks in advance for any guidance.

• Java stored procedures

  Hello. I am quite new to this feature, and I know, java stored procedures are built and called with a static method. My questions are:
  
  receipt of several requests, are processed in parallel or they are serialized?
  * If, at the same time, it is possible that the son has and b b finishing in the first place, I get the result of b to a?
  * If it is sequential, isn't it a bottleneck?

  Thanks for your help, but what I understand from your answer, that this means that, for example, in the case many processes accessing the same java stored procedure as all requests are serialized and handled one by one. Is this correct?

  N ° number of connections to the database simultaneously executes the same java stored procedure.

  It's not not clear to me what happens if I have multiple threads opening their own connections and access this stored procedure, or, on the other hand, if I have a process that opens up multiple threads, but with a shared connection.

  If you have multiple threads, each with their own connection to the database, they each will perform the same procedure at the same time. If you have multiple threads sharing a single connection to the database, then each thread won't be able to run the one-at-a-time procedure, given that the connection can only be used by only one thread at a time.

  The JVM in Oracle is NOT mono-thread. You can create a java stored procedure that creates multiple threads within the database, and they work simultaneously. However, there is NO case where this would be an appropriate design.

• Creating classic report to the stored procedure.

  How can we create a report based on a stored procedure out parameter.

  Can someone please help.

  Thank you

  Out parameter is a multi-level object type.

  I found a way to sort of basis a report on the parameter OUT procedure. The approach is:

  1. call the procedure in a process before PL/SQL areas, convert the object returned in an XML document and store in a collection XMLType column:

  declare
  
    k_rate_query varchar2(255) := 'RATE_QUERY';
  
    l_rate_type_code  number;
    l_rate_query      rate_rec;
    l_xml             xmltype;
  
    l_seq_id number;
  
  begin
  
    l_rate_type_code := to_number(:p1_rate_type_code);
    api_pkg.rate_query(l_rate_type_code, l_rate_query);
    l_xml := xmltype.createXML(l_rate_query);
  
    if not apex_collection.collection_exists(k_rate_query)
    then
      apex_collection.create_collection(k_rate_query);
    end if;
  
    select
        seq_id
    into
        l_seq_id
    from
        apex_collections
    where
        collection_name = k_rate_query
    and n001 = l_rate_type_code;
  
    apex_collection.update_member_attribute(k_rate_query, l_seq_id, 1, l_xml);
  
  exception
  
    when no_data_found
    then
      apex_collection.add_member(
          p_collection_name => k_rate_query
        , p_n001 => l_rate_type_code
        , p_xmltype001 => l_xml);
  
  end;
  

  2. use a SQL/XML query on the XML collection in the region report source:

  select
      rq.*
  from
      apex_collections ac
    , xmltable(
          '/RATE_REC/RATE_TBL/RATE_REC_TYPE'

• transaction isolation stored procedure-level testing

  Hello

  I want to study the concurrency in the Oracle database using stored procedures in pl/sql with different transaction isolation levels.

  The idea is to send to the database of a number "n" of simultaneous transactions where n can be {100, 200, 400, 1000} and for each isolation level (READ COMMITTED, SERIALIZABLE) to determine the number of transactions committed, how much data, run time incorrect.

  The question is how can I generate n transactions that run simultaneously on the data base and how to get these results. I understand that this task can be done as well by using pl/sql stored procedure in the database or inside a JSP Java web application. Advantages/disadvantages?

  I should mention that I'm a begginner in Oracle...

  Thank you in advance.

  You want to run a large number of asynchronous (parallel) transactions.

  Although this can be done by running the Oracle's work, I think it is easier to work with the client side, using a Java program (for example).

  It doesn't have to be a web application (for example. JSP), can be a client Java that uses Java threads, and each thread is using a single database connection (and the corresponding database session).

• Implementation of a parallel process using DBMS_JOB

  Hi all
  
  We use oralce 9.2.0.8.0 d/b,.
  There are procedures (3) running for each provider sequentially and inserting/updating of values in different tables
  These jobs longer account of the needs both to reduce the time to take for these jobs.
  
  I am using dbms_job to treat this work in parallel so that all tasks will run in parallel.
  
  is that this approach will lock the tables at the level of the table or simply stored?
  
  I can't able to establish the parallel process on planning the tool itself, which is the best approach...?
  
  do I need consider as all other settings before approacing... ?

  If two different jobs insert 2 different rows in the same table then so there is no problem locking?

  If you have a table with no index, no trigger, etc. two sessions making INSERT operations are never blocks between them. If you have no trigger, no index bitmap and you can ensure that only unique index on the table is a column on which no two sessions will never be in conflict, the two sessions does not block each other.

  I am a little concerned by your description of the index, however. It does not seem logical that something like unique VENDOR_ID otherwise than in the VENDOR table. You say that each session has a different VENDOR_ID which seems to imply that there are only 3 values VENDOR_ID (one per post). Which implies that he can never y 3 rows in the table (one per VENDOR_ID) which seems unlikely in particular where you plan jobs running in parallel.

• Tables created in a stored procedure cannot be used with dynamic SQL? The impact?

  There is a thread on the forum which explains how to create tables within a stored procedure (How to create a table in a stored procedure , however, it does create a table as such, but not how to use it (insert, select, update, etc.) the table in the stored procedure.) Looking around and in the light of the tests, it seems that you need to use dynamic SQL statements to execute ddl in a stored procedure in Oracle DB. In addition, it also seems that you cannot use dynamic SQL statements for reuse (insert, select, update, etc.) the table that was created in the stored procedure? Is this really the case?
  
  If this is the case, I am afraid that if tables cannot be 'created and used"in a stored procedure using the dynamic SQL, as is the case with most of the servers of DB dynamic SQL is not a part of the implementation plan and, therefore, is quite expensive (slow). This is the case with Oracle, and if yes what is the performance impact? (Apparently, with Informix, yield loss is about 3 - 4 times, MS SQL - 4 - 5 times and so on).
  
  In summary, tables created within a stored procedure cannot be 'used' with dynamic SQL, and if so, what is the impact of performance as such?
  
  Thank you and best regards,
  Amedeo.

  Hi, Frank.

  Thank you for your response. I understand that the dynamic SQL is required in this context.

  Unfortunately, I am yet to discover "that seeks to" using temporary tables inside stored procedures. I'm helping a migration from MySQL to Oracle DB, and this was one of the dilemmas encountered. I'll post what is the attempt, when more.

  In Oracle, we use [global temporary Tables | http://www.psoug.org/reference/OLD/gtt.html?PHPSESSID=67b3adaeaf970906c5e037b23ed380c2] aka TWG these tables need only be created once everything like a normal table, but they act differently when they are used. The data inserted in TWG will be visible at the session that inserted data, allowing you to use the table for their own temporary needs while not collide with them of all sessions. The data of the TWG will be automatically deleted (if not deleted programmatically) when a) a commit is issued or b) the session ends according to the parameter that is used during the creation of the TWG. There is no real need in Oracle to create tables dynamically in code.

  I noticed that many people say that the "Creation of the tables within a stored procedure" is not a good idea, but nobody seems necessarily explain why? Think you could elaborate a little bit? Would be appreciated.

  The main reason is that when you come to compile PL/SQL code on the database, all explicit references to tables in the code must correspond to an existing table, otherwise a djab error will occur. This is necessary so that Oracle can validate the columns that are referenced, the data types of those columns etc.. These compilation controls are an important element to ensure that the compiled code is as error free as possible (there is no accounting for the logic of programmers though ;)).

  If you start to create tables dynamically in your PL/SQL code, so any time you want to reference this table you must ensure that you write your SQL queries dynamically too. Once you start doing this, then Oracle will not be able to validate your SQL syntax, check the types of data or SQL logic. This makes your code more difficult to write and harder to debug, because inevitably it contains errors. It also means that for example if you want to write a simple query to get that one out in a variable value (which would take a single line of SQL with static tables), you end up writing a dynamic slider all for her. Very heavy and very messy. You also get the situation in which, if you create tables dynamically in the code, you are also likely to drop tables dynamically in code. If it is a fixed table name, then in an environment multi-user, you get in a mess well when different user sessions are trying to determine if the table exists already or is the last one to use so they can drop etc. What headache! If you create tables with table names, then variable Dynamics not only make you a lot end up creating (and falling) of objects on the database, which can cause an overload on the update of the data dictionary, but how can ensure you that you clean the tables, if your code has an exception any. Indeed, you'll find yourself with redundant tables lying around on your database, may contain sensitive data that should be removed.

  With the TWG, you have none of these issues.

  Also, what is the impact on the performance of the dynamic SQL statements in Oracle? I read some contrasting opinions, some indicating that it is not a lot of difference between static SQL and SQL dynamic in more recent versions of Oracle DB (Re: why dynamic sql is slower than static sql is this true?)

  When the query runs on the database, there will be no difference in performance because it is just a request for enforcement in the SQL engine. Performance problems may occur if your dynamic query is not binding variable in the query correctly (because this would cause difficult analysis of the query rather than sweet), and also the extra time, to dynamically write the query running.

  Another risk of dynamic query is SQL injection which may result in a security risk on the database.

  Good programming will have little need for the tables of dynamically created dynamically or SQL.

  Even if you have installed a third-party software ('Parallels' and a 'Promise' device driver) who is likely to cause a kernel panic, the kind of panic you are most likely caused by a hardware failure. I suggest that you take the machine to an Apple Retail Store or other provider of services allowed for a stable service and guaranteed, if necessary.

• Implementation of the synchronization steps without using batch or parallel processing sequences

  We use a model of customized integrated process based on sequential process model.

  I have to call the Synchronization Manager in order to use the steps of synchronization when you do not use batch or models of parallel process?

  All operations (locks, Rendezvous, Notifications, queues, etc.) and the steps of synchronization works in any model or a model, with the exception of the synchronization of the lot.

  If you need batch synchronization, your model must use synchronization > advanced > step type specification of batch processing to specify what threads are in the batch. Since you are not from the model of batch processing, I doubt that you have to worry about this.

• Urgent: continous recorders of NIDAQmx and other instruments with multi-threaded vc ++

  I'm working on a software with vc ++ to control several instruments including a NO-DAQmx6289. For example, the features of the software.

  1. communicate with data acquisition card (card data acquisition) and continuously acquire data from several channels at a frequency of 1 kHz.

  2. connect with function via port RS232 1 generator, sending triggered bursts to the real-time features generator change state Ultrasound (G_usstatus) variable.

  3. connect with optical switch via RS232 2 port, send signals to switch between the two input channels (0,1) and six output channels (2,3,4,5,6,7) to the specified user to sequence and time interval (default: 150 ms), real-time change the channel connection variable (G_optchannel).

  4. in real-time, record data and the corresponding ultrasound status and connection status of optical channel in a specified file use for later analysis.

  I use multiple threads to make data acquisition (1-wire), control of the function (2 wire) generator and optical switch (3 wire).  I also need save data acquisition of data and the corresponding ultrasound status and use the connection status of optical channel in a specified file for later analysis. I use the following codes to read data continuously.

  Now the problem is the data acquired with daq card does not match the corresponding registered swtich optical status (G_optchannel, which specifies the light connecting channels). High readings expected certain status really appeared in any other situation.  It seems that there is a misalignment of the multi-thread data. Because the optical switching State passes to 150ms, so I put DAQmxRegisterEveryNSamplesEvent to be trigued each 50samples, which means 50ms with 1 kHz sampling to avoid missing the changes. I also check if there is any change of status during the DAQmxReadAnalogF64, by registering l_optstatus_s and l_optstatus_e, which are actually the same. I wonder if this is because the data are first registered in the buffer. When the software starts reading, at that time, optical swtich status no longer reflects the State when the data was recorded first. Is it possible to fix this?  Thank you very much!

  kGy,

  I'm glad to hear that you are progressing with your project.  Timestamp data are always a bit tricky, because the process of querying a counter on the CPU is done asynchronously with the acquisition of your DAQ hardware.  However, your equipment will ensure that the relative chronology between samples is consistent (in your case, the data will be sampled every 1 ms).  And since you have changed your program as you are now all samples acquired reading, you know that each sample follows the previous 1ms.  So, if I were to implement this I think that I take an initial horodotage when I started the task and to calculate the timestamp for all samples following this timestamp (timestamp SampleN = (*.001s + horodotage initial N) or timestamp SampleN = timestamp SampleN 1 +. 001 s).

  I would go to do that, rather than the timestamp of the end of the reading for the following reason.  As I mentioned previously, the reminder of your reading will run when the OS is planning.  Therefore, it is possible that it gets delayed or does not exactly in phase with the acquisition of hardware, and make adjustments to your code to handle this problem.  However, when you're timestamping there is another thing to pay attention to.  It's the fact that your hardware has a FIFO where sampled data can accumulate before getting transferred to the memory buffer that reading from (for example if the bus PCI were busy when the sample was acquired).  Now assume that the stars aligned against us and get the following:

  (1) the operating system is busy with other things, and our reminder read gets delayed a few ms.

  (2) at the same time, another device connects the PCI bus (or part of the data path between your device and the memory used for the buffer).

  (3) one or more samples is momentarily blocked in FIFO of the device.

  If you were to read data timestamp at the moment, your timestamp would reflect the data in the buffer as well as data that was flying in the FIFO of your device.  However, you can only read data in the buffer.  Thus, time stamp applied to data that you just read would be a millisecond or two later they should be.  Suppose that on the next read reminder, this condition has cleared up itself.  This timestamp taken here would be accurate, however, you will need to return some additional samples (those who were stuck in the FIFO last time).  If you backcalculation your timestamp at this stage, I think that the timestamp calculated for these ecaple timestamps calculated on the previous reading.  It wouldn't be ideal, nor would it reflect when the data has been actually sampled.

  One of the remaining challenges is how exactly the start of time stamp feature.  To do this, I would like to add a call to DAQmxTaskControl (taskHandle, DAQmx_Val_Task_Commit) before calling DAQmxStartTask.  This step will advance the State template DAQmx as far as possible without actually starting the task.  This will help to DAQmxStartTask as soon as possible.  Now, before the appellant beginning or immediately after, I would take my initial horodotage (perhaps timestamp before and after and take the average).  Then I would use this original time stamp and my sampling rate known to calculate timestamps for all the rest of my samples.

  That got a bit long, but I hope it has been helpful.

• Stored procedure

  I can't using stored procedures and need advice.

  If I try to run the stored procedure code, I get an error saying that I not provided a required entry, but the LabVIEW looks I'm him.

  

  But I get this error message.

  

  The database table is as follows:

  

  @ID is generated in the process, he is looked at and inserted.

  I don't have the opportunity to get into the database.  It is a stored procedure of writtin by the DB of my COMPUTER service engineer.  The image above has the required fields highlighted in yellow I need to provide when executing my code.

  Can you see where my mistake was made?

  Thanks for the comments.

  Ben

  The procedure does not match the names of parameters with the values that you provide.  You provide only 5 params, but there are 8 in the stored procedure.  In your case, SerialNumber is spent in the ID, PartNumber in SerialNumber, etc..  Add some empty in your cluster params, if they are not mandatory.
