Structures of parallel event on the same trigger events

Based on information gleaned in this thread [using ends records], I think what I'm trying to do is impossible and so intentionally. But it would be so nice. Here goes:

Given an event and two dynamic records for this event, is it possible to capture the event simultaneously in two structures Parallels event?

I understand why it is generally undesired behavior, but it save me considerable grief [vote]! If it is possible. Here's what I do [uh, trying to do]:

I have a set of SVs published network which are written in an acquisition of data VI. A VI of dynamically fits to the OAS events, Web method handles events [send new values SV making HTTP], and then unregisters before complete execution. When I run the VI web method via a URL request, the client sits and waits for a response until the SV is written to, and then correctly receives the data from the web method VI. So far so good. However, there are two cases where things go very wrong:

1. several customers call the web method

2. a single client calls the web at a rate faster than the rate of events

In both cases, several instances of the web method are active and pending events simultaneously. When a new SV event is generated, one of these web methods it will resume. In the first case this means that only one customer will receive the new data. In the second case, no SV event is detected indefinitely - web method instances in addition to more accumulate. Even if I use a case of timeout to kill the old instances of the web method, the OLDEST we capture new events and the client will not recognize a response to the new instance.

I anticipate using the customer of the poll, although it will be not as pretty as using the structures of the event. Am I wrong?

  • What happens when two parallel process call the same VI in an FPGA?

    Hi all

    I was wondering, what happens when say two parallel processes call the same Subvi in an FPGA? I think that the FPGA would create two instances of the Subvi, not sure. Any point of view?

    Thank you

    Altras

    I don't know if the FPGA adds any ordinary special, but in LabVIEW rule and in LabVIEW Real-time, a VI by default is not reentrant.  Therefore, a process that is called when it is already in use is blocked and must wait.

    If the VI is reentrant, however, then you have two (or more) for the VI dataspaces, so that each can run independently.

  • Can different symbols share the same trigger?

    Hello!

    I have 4 buttons all on the same animation timeline. Each is the text which is transformed into a symbol.

    buttons.jpg

    I used .play sym.getSymbol (' about ') ("over"); for each with their symbol names respective in the hope that each with triggers individually, but the passage of the mouse on one triggers the rest too.


    Can someone point me in the right direction pls? THX!

    Hey Mate,

    sym.getSymbol("about").play ("over"); asked to play a timeline of a symbol called "a connection".

    However, this isn't what is implemented.

    If you type sym.play("over"); what awaits you is that all of the contact/Gallery etc will animate.

    you create a symbol for each button and copy the details of these triggers and animations in this symbol OR if you want to use the chronology of the scene (recommended only if a basic composition or a site), and then spread these out animations and triggers.

    galleryOver and IE aboutOver

    Better to create an individual symbol for each button and then click on "open actions' for each of these buttons and add the mouse enter / leave mouse / click actions here.»

  • Pools of multiple connections to the same physical Structure with SPR

    I use OBIEE 10.1.3.4 and have multiple physical databases that contain the exact same structure. Instead of creating the same physical structure in the RPD file with their own pools of connections, I would like to have a physical structure with multiple connections pools. I have this Setup, however, I can only see the data of one of the physical databases by using the right click, view data... option in the physical appearance of the RPD file. I searched and could not find a solution to my particular problem. Can someone point me in the right direction?

    Goal is to get the CPs separated... and then, you can use two data. But better to have 2 separate objects.

  • Several instance to the same server with same ORACLE_HOME and same SID

    Hello gurus, reduce costs my company looks to reduce the backup servers and the databases consolidade waiting on big 2 or 3 servers to reduce oracle licenses.
    It is that I have about 30 cases with SID same how to configure it to run as 10 instances with the same SID, ORACLE_HOME in the same machine? is this possible?

    will run oracle on unix HP - UX 11r2

    BR

    TI

    Right. Each database will have own SID. With multiply tnsnames.ora and listener.ora all have entries for each standby.

    If the folder structure is different from primary then the DB_FILE_NAME_CONVERT and LOG_FILE_NAME_CONVERT parameters are used to convert to the new locations.
    These two taking input in two, the front of the location and the location after.

    Example:

    DB_FILE_NAME_CONVERT=('/u01/app/oracle/oradata/RECOVER2', '/u01/app/oracle/oradata/RECLONE','/u01/oradata/RECOVER2','/u01/oradata/RECLONE')
    LOG_FILE_NAME_CONVERT=('/u01/app/oracle/flash_recovery_area/RECOVER2', '/u01/app/oracle/flash_recovery_area/RECLONE')
    

    Standby for each primary SID can be all that you need. The DB_NAME parameter would be the same on both, but DB_UNIQUE_NAME would be different.

    Who is?

    So, if I have two PRIMARY and standby database, Eve will have its own password, its own file INIT file to its own directory structure (but it could be the same).

  • R12: Copy a group of companies with configurations, metadata and data in the same instance of OA

    The idea was born to a very common condition between the companies IT. pre-sales and pro-ventes groups do various tasks, including the response of the RPF/RFI, PoC, building, Solution architecture, customer demo etc. Ususally they do not have the dedicated application instances, or rather they do not find a sufficient number of cases of applications dedicated to deep study of the road. Every other day a group cries out for an Apps instance and the same gets lift for senior management in short time. It gives a lot of pain to the infrastructure/DBA groups because they fail to meet people like them, due to the limited availability of free nodes, resources, networks and space etc.

    I have a Vision of the R12.1.3 (tell SID = VIS1213) installed on a Linux machine. The box is quite busy with his hearts limited, showing little free memory and the attached SAN has insufficient free space remaining. A group of Oracle Apps pre-sales consultants, says "Group 1", is the use of this.»

    Now the 3 other groups are asking for a R12.1.3 Vision instance separately for different reasons below. Each of them wants the instance again and do not share with others.

    Group 2 for deep study of the road against a critical response to RFP
    Group-3 for the development of a point of contact for a customer demo
    Group 4 for the manufacture of PUK media on some business processes

    In this scenario, I should install 3 distinct Vision of R12.1.3 (using CDs or downloaded zip) or clone VIS1213 in 3 different places with different SIDS, possibly on one or more separated nodes (as above Linux node has insufficient free resources). In this case, the need for available server resources and disk space multiplied by 3, so that DBA maintenance for these 3 new instances is added.

    Hope that I have clear air up to this point.

    Then I was thinking if we have "virtual instances" within an existing instance of Apps, by copying from a vertain org level. First I thought I'd take THE level, but it will not work if an instance of group to work with HRMS claims. We must therefore take business group level. After that we will create the appropriate role and responsibility, user profile options so that the new user can see and work on the new BG and data area down only. It will be like a separate instance to use.
    Benefits of my desired task will be

    -no separate server resource, the required network
    -no additional DBA not involved maintenance
    -no separate required backup plan

    So here it is to create 3 new "virtual instances" right within the same instance of VIS1213. New groups will have same URL, same existing TNS details but 3 credentials different existing access. Each of them would be limited in a way so that they can not see each and other data and can not hurt each and other changes.

    This can be achieved if we can copy an existing group of its activities with org structures, metadata and data, within the same instance. Oralce planning cannot be copied within the same instance configurations.

    What I've done so far was I manually created a new BG, attached an existing sobbing (CoA, Agenda / currency), created a new, copied and modified accounting structure flexfields before fixing, created the new ORGANIZATIONAL unit, and then a new InvOrg of master and a new InvOrg clild, defined the profile MO some GL and HR profiles. Then I extracted finished master and data assignment article category Masters against a master/child existing InvOrg, updated the data for newly created InvOrgs, inserted into tables insterface and ran seeded import conc program element. Except for a few, all data have been loaded into base against new InvOrgs tables.

    Then I tried with master provider (with sites and contacts). A few AP configurations are required, and then data provider (+ contact + site) have been loaded against OR newly created (under new BG) base tables.

    I do not proceed after that. I'm currently looking for ideas from the experts on how to go further.

    Planning is able to create this kind of 'virtual instance' within the same instance of OSTEOARTHRITIS?

    PL nowadays return.

  • How to create a DHTML menu link drop-down text involving an object in the same section?

    Hello!

    What I want to achieve is related to a post earlier this week (trying to run 2 targets with the same trigger). The workaround is to insert a link in a menu drop-down text saying something like "Click here to see this area on the image below", but I can't get this trigger to work.

    What I did:

    1. Create as target a text box placed around the area on the image.
    2. Do trigger on a word in the text of the menu drop down.
    3. Using the drum next to the trigger, try to bind to the target.

    The link of the drum don't cross in front of the menu text editor drop-down.

    Anyway to make it work otherwise? Work at home since Tuesday, I can't.

    Thanks again for your help, it's really appreciated.

    Hello

    Here's how I'd do. I absolutely HATE this small editing window. Yes!

    Build the text you want as well as links and triggers in the main part of the subject. Overall, I'm doing this right where the drop will be finally considered. Then select this option and cut in the windows clipboard.

    Now open the cuss pesky lil of a window and select all the items inside. Paste that cut you earlier.

    I said I don't like the small window? I thought I might have.

  • Is it OK to trigger 2 loops of event out of the same control?

  • At all indexes on tables of the same value in the structure of the event

    Hello

    I have a panel with the four bays and I use a structure of the event.

    Now, I want that change of the index of array_1 also affects the index of 3 other tables at the same index.

    But there is only a property "value Exchange" and no property 'index-change' in the properties of the table.

    So I read the 'index' property and write in the other table.

    But: It seems as if I have to do so within the period of waiting-section of the structure of the event.

    Is there another way to do this?

    Thanks for help

    You can use the mouse event on each table to detec the event (of course, that will attract not only a change of index, but I don't think you care too) and then use the 'values of the indices' property on all the table to set.

    See annex VI (LV2012), hope this helps

  • How to stop the While loop in the Structure of the event with the same button?

    Hello

    I have a problem. I want to use a single control to activate an event in a structure of the event and the same control to end a while loop in this case.

    It is possible to use 2 controls to do this, but I need to be alone.

    Thank you

    You should NEVER place while loops inside the case of the event, and it is never necessary to do. Think about it: all you have to do is spin the code. You can easily use the outside while loop for everything. Simply place the code of the loop internal (without the inner loop) inside the case of delay and manipulate the time-out period between a pending finished and the infinite (-1), depending on the State of the Boolean value.

    A very simple example (LV 8.0)

  • Can I have several structures with the same case of event event?

    Hello

    I do an application which reproduces the front of the power supply HP6675A. To do this, I did a machine to States with different States

    (initialize, measures, voltage, current, ocp, ov, store, recall, etc.). In each State, should have a structure of the event that attracts the events of the buttons, as for example: If the current state is the voltage mode and the current button is pressed the next State will be the current mode. For this purpose in each State of the state machine should be the same structure of event with the same events.

    My problem is that the Vi does not work properly when I have several structures with the same case of event event. There are some possibly to do and how? Or is impossible to have several events? I read a few posts, but I can't find solutions.

    Any help is appreciated.

    Thank you very much.

    In general, you should have 1 structure of the event in your VI.  In your state machine, the structure of the event should be in "pending" status  So you will probably start in the State of the initialization and then spend idling.  Then, the user presses the present button.  If your state machine should then, go to the current state and then return to Idle.

  • Use the same graphical display of data from the different cases of event Structure

    Hello

    I would like one graph to view the input data and modified by one of the two cases of different event structure.  So if the event 1 is selected by the user, the data would be entered by the code contained in 1 case and then introduced in a waveform to display chart.  If the event case 2 is selected, similar data would enter the 2 cases but then displayed by the same graphic waveform , as in case 1.  I don't know if there is a way to do this... it seems that each case of the event would need its own array of waveform, but it becomes quickly heavy regarding the graphical interface for the multiple cases of event.

    Advice would be greatly appreciated!

  • Using more of a structure of the event for the same control in a machine to standard reports

    Hello

    I'm working on a test sequence using a machine standard reports in the examples of LabVIEW.

    Part of my test, I displays a waveform on a graphic scale. The entry for this is a PXI-4070 DMM. This goes into a "while loop" update permanently the waveform. The screen simulates an oscilloscope. The test operator must make adjustments while watching this screen. This bit is working and I have no problem here.

    On my front, it has a "continue" button to the next part of the test once the adjustment is done. Some changes are then made to the configuration and the following adjustment must be made the same way, that is to look at the screen, make the adjustment, press on ' continue. Is where I have the problem.

    I tried using the event structures in the while loop the loop stops when you press the button continue. This works for the first adjustment, but when the test arrives at the second stage of the adjustment, the event seems to "remember" and the loop ends immediately.

    Is it far from resetting the event so that the button can be used again in a good way

    Kind regards.
