Question about the Manager of messages in queue and dynamically load/close Subvi

Hi, my dear LV users

I learn how to use the machine in queue Sate Architecture. I created a simple project, including a "main.vi" to dynamically load a sub vi 'sub_Vi2.vi' in the case of "initialize". The sub vi simply open a configuration file and load affecting some control and write these values in the configuration file. If the configuration file is not created, the sub vi creates until the user closes the Subvi.

In the case of "Get out" of my "main.vi", I send 'true' to the Subvi stop button to stop running it. But the sub vi did not write these values back to the configuration file, or created a new when I delete the configuration file.

There is another vi I made 'main1.vi', which loads dynamically and close the Subvi. And it works as well as I expected: create the file and write data!

Can someone help me understand the code? I've also attached the front of diagrams and source code. It's in 2012 LV.

Best regards

Li CQ

  • Questions about the management of specific nodes in different hierarchies

    Hi all

    I have a question about the specific management of some particular set nodes, which are located in different hierarchies within a same version.

    I want to know if there is any editing made to certain properties of these specific nodes or if the nodes are deleted/moved/edited approval to be triggered for the data manager.

    or should not allow users to edit (adding/moving/deleting/changing property values) or those specific members.


    According to my understanding of the nodes of domain prevents the removal of nodes, but I don't want my Member prefix/suffix, domain is the only way to prevent the change.




    Thanks and greetings

    Madhu

    We have an obligation to not allow a node to remove or deleted without the approval of the admin, so I created a Boolean property AllowDelete is false, which is substitutable, default and is available only in a category of property Admin, for which most of the users do not have access.  Then, I created a validation of PropRemove with an error message that tells the user to contact a user admin to remove or delete the node.  The admin can change the AllowDelete to true, then can either remove himself or to allow the user to do.

  • Questions about the implementation of clusters of storage and DTS on active cluster

    I have a few questions about the implementation of clusters of data store and SRS storage in VSphere 5.1.

    We have a data center with about 15 HP blades and a few servers non-lame.  The hosts are all either VSphere 5.0 or 5.1.  Our back-end storage is an EMC VNX 5700 with about 20 stores of data.  All the VMWare is managed by VCenter 5.1 running on a dedicated physical machine.

    Currently, each data store is used individually; No piles of data store are put in place.  When a new virtual machine is created, the administrator usually chooses the data with the most space store.  Periodically, we will go back and manually storage vMotion machines to balance the load.

    Recently, we have expanded the VNX storage, so we now have LUNS in different pools, with different levels of performance.

    What I would do is set up for the data store clusters, so that us when a virtual machine is created, the administrator must not know what data store is in which pool.  Also take advantage of the DRS storage so that the burden of storage will be "refine" himself a little.

    I know the setting up of a cluster of storage in a 'clean' environment is quite simple, but my concern is creation/conversion data warehouses existing in active production in the cluster, while they are used.

    If I access the screen "data warehouses and store data from clusters ', right-click on the data center and create a cluster, and then move the various data stores in the new cluster, will there be an interruption in the production running systems?

    I also wonder about activation of storage i/o control.  It is not currently enabled on data warehouses.  I know it's useful for the StorageDRS, but will be allowing any negative impact on the system?  If I turn on the warehouses of data, is there anything else I should do or set in addition to all that allows him?

    Finally, we are in the process of Site Recovery Manager configuration.  SRS has an impact on the configuration of the data clusters and DTS store?

    Thanks in advance for your comments.

    Hello

    Clusters of data and using DTS store doesn't impact RS even if you create a cluster of data store for storage of replicated data and another for everyone else, this way you machines virtual you want to replicate are not moved on warehouses of data that are not replicated , but will still have the ability to move if there is a conflict.

    Gregg

    With all due respect but SRM and DTS don't go together. SRM does not at all support the use of DTS. So if you are configuring SRM forget DTS for now.

    Reason for this is that SRM knows no DTS and VMs can be in flight when a failover should occur, and bad things can happen. Also, the protection breaks when a virtual computer is moved between data warehouses in a cluster data store.

    In short: don't go there.

  • Question about the database to use with ESX and Labmanager

    Hello

    Finally my company is buying a permit for Labmanager and ESX server using Labmanager to our tests.

    We had a question about the database that we use for the actual installation.

    Could we use MY - SQL? Or that we have the olbigation to install a SQL or Oracle DB for the whole system to work?

    We prefer to use MY_SQL because it is open-source and will cost less to use for us.

    Thanks in advance for the answer and please excuse my bad English, I'm french spoke first.

    Montreal.

    Lab Manager installs SQL Express as part of the installation and use. If you install also Virtual Center as part of your deployment of Lab Manager (do not use an existing VC server), you can use the database SQL Express is included for small installations of ESX, but MY SQL is not an option. You can search the databases supported in the installation guide for what version you deploy.

  • Question about the function of "Messages"

    Hi all

    I'm trying to use the feature of Message workspace to inform our users of planning that are connected on downtime etc. While working with the feature, I noticed something-

    The broadcast Message is sent by the admin looks like a pop up but only when the user navigates on the current page to another page. He does not appear when the user is working on a dataform and refreshes the data form or things, another option. Depending on how it works now lets say a user is already connected to the planning application and works on a dataform and is just save/update the data in the form of data, it will not see the message at all.

    Is there something I'm missing or there at - it another way for the message box is displayed even if the user is hitting refresh? I continued through the broadcast Messages Oracle documentation and it says:

    "+ For users connected to the application, the broadcast message displays in their browser the next time they refresh the page or go to another page, if you send the message via the Web or the command line." + »

    but it doesn't look like it works when you click Refresh.

    Please let me know your opinion on this. Any help is appreciated.

    Thank you.

    I think what you see is just the way it works in 11.1.2.1, might be worth totalling a call at Oracle, if you think this is a bug or maybe it has already been addressed.

    See you soon

  • Question about the management of feeding on Satellite P30

    Hi all

    I ve just had to replace my hard drive on my Satellite P30 in which I lost everything!
    Before that, I had a program including the fan speed and cooling c.p.f. set.
    I thought that it was the Toshiba power saver but I tried to install this and it seems that it s not the same
    program that doesn't do these things.

    My laptop seems completely disable when I m a game,.
    in the past I've refused the c.p.f. a level that seems to do the trick which I just can't do it now.
    He was an icon that looks like a pile of Paolo if that helps.

    Help, please?

    If the laptop is full of dust, and I can imagine that P30 can be pretty dusty after so long, I don't think the air blower it will be clean again. I had P20 and after two years of use, there was so can dust inside and cooling grill has been blocked.

    The laptop does not turn off, but it was strong enough and cooling fan was running without permanently.

    Anyway, I don't know what program you used but for Toshiba P30 offered own tool to optimize the system and power consumption.

    Did you find the name of this program?

  • Two questions about the ACS 5.1: password aging and allowing multiple disabled accounts

    Hello

    I test in ACS 5.1 password aging, and I discovered that you can have only one global setting for the password for all the accounts internal life. Is it possible to exclude some internal accounts of this global password aging policy? I would like to have number of accounts, passwords should not be aged at all...

    Second question: when I was testing password aging, I set myself to life of password in 4 days with warning after 2 days. All accounts in my test of the ACS configuration are now disabled, because 4 days has passed when I changed it. Is there a possibility to allow multiple accouns at once, or do I have to activate 500 internal accounts manually, one by one?

    Thanks in advance

    WM

    I'm not aware of any way to score internal as users with passwords as enver expire. This is done for admins ensure there is always an admin who can access the system

    In order to change the multiple/all documents for internal users, the following approach can be taken:

    1. Go to the list of internal users and press "Export" then 'Start export' and 'Save file' export user records to a csv file
    2. Edit the file. In the title 'active' column replace 'FALSE' to 'TRUE' for all records. Save the updated file
    3. To the page that lists internal users, tap "File Options", select "Update", and then click next to access the section "Import a file" Wizard. Select the file saved in step 2) and tap on finish

    Afetr imort is completed, all records of internal user should now display "Enabled".

  • Question about the migration of mass of files and permissions

    Hello

    I'm moving 2TBs of files from one external hard drive to another, but every time that I try to do a file mass transfer from one day to the next it eventually fail due to permissions for some files. I looked at the files on that he objected and I read and write permissions on them, as you would expect.

    What can I do to fix this?

    Try to run repair permissions and ACLs on your record. A repair permissions with disk utility does not have anything in your folder. Boot from your recovery partition now command-keys R in the menu utilities launch Terminal. In the Terminal, type: resetpassword , then press return.  (Note: you won't be reset password)

    Click the icon for the hard drive of your Mac at the top. In the drop down menu below, select your home folder. At the bottom of the window restore Home Directory Permissions and ACLs. Then, click on the Reset button. When the prompt returns to the command line, you can leave out Terminal.

  • Question about the upgrade to ESXi 4.1 and USB keys

    Right now I'm under ESXi 4.1 from a USB key (ie. a very small USB key).

    If I want to "start over" and use a newer USB for ESXi 5 but keep my intact, is guest operating systems - this possible?  (For example, if I install ESXi on a Virgin USB 5.0, will I be able to import my existing operating system vmx ESXi 4.1 images, etc.?)

    In addition, what's the downside of ESXi 5 running from a USB?  I spin this in a laboratory at the House and have read that ESXi basically load into memory if you really start player ESXi itself is useless and a USB key is perfectly fine.  Is this true?

    If you do not want re - configure ESXi 5.0, you can proceed as follows:

    1. Use free software, called "USB Image Tool 1.57" make a picture of your USB 4.1 - software available here http://www.alexpage.de/usb-image-tool/ .  This way you can restore it to any USB in the future.
    2. After making a backup of your USB 4.1 image, upgrade installation 4.1 to 5.0.
    3. Make a backup of your configuration of ESXi using the CLI vMA tool / vSphere in Windows with the following command: vicfg-cfgbackup-next - server
    4. The new installation of ESXi 5.0 on new USB
    5. VMA or vSphere CLI tool use in Windows with the following command to restore the backup from step 3 config: vicfg-cfgbackup-load - server
    6. You should now have ESXi 5.0 works on a new USB without any necessary configuration

    Alternatively, you can restore the image USB created in step 1 on your old USB in order to have a 4.1 installation handy...

    I recommend that make you a picture of your USB 5.0 USB as well just in case in the future USB fails.

    Hi Daniel,.

    Well I am fairly new to Siebel as well. Your basic documentation should be Siebel Bookshelf. There is also a lot of useful forums and articles about Siebel to start to learn...
    for the need, you can try searching for a user property called 'on Update Set field' in the library. With its help, you can set a field in dependence of another field. That would be a possibility in my opinion.

  • A few questions about the management of the partitions when you perform a recovery

    Hello everyone,

    I bought a L505-13Z on weeks there are for personal use and editing of audio work light. In these two weeks, I took the time to explore and test the performance of this computer and judged suitable for my needs because it resists even havier audio work so I'll need, what it is tested. I am really satisfied with this laptop! In any case, some optimizations I did for audio software suffered a few necessary features of the computer, so I need to reinstall the operating system... Basically, I was always used to install only the system drive wiping system, leaving the score of "D: Data" intact. I noticed that this is not the case with the recovery of the system, because after the restoration, system partitions and data disappeared. of course everything is saved on an external drive, but every time I have to restore, I need to copy everything back from the backup drive? I missed the point of this - it's exactly like having all my data saved on the system partition. What, then, is the need for the data partition?

    Is there a way to recover and leave intact the partition 'Data'?

    My second question is if it is possible to change the size of the partitions somehow? I think it's a bit pointless to have 230G of free space for the system partition. 100G is sufficient for my needs, and I could use the 130G remaining for the data partition, I don't know why the drive is simply divided into two by default... (I am aware that a change of size of partition must erase all data on the disk).

    Thank you all in advance for any help!

    If you use the procedure of recovery disc HARD - http://aps2.toshiba-tro.de/kb0/HTD9102IR0000R01.htm - structure and the data on the second partition will not be deleted.
    So, if you want to install OS using HARD drive recovery option you can move all the important data of the C partition to D partition.

    The whole HARD disc will be deleted if you use recovery DVD for installing the OS.
    ----------------------------------------------------------
    You should not change the partition structure because it can have a negative influence on the recovery procedure more HARD drive. It can happen that data recovery will be will be more found.

    Please note: second partition D is not a kind of system partition or recovery. This is normal and usual HARD disk partition. He is saved just Toshiba recovery image in the folder called HDDRecovery.
    You can do it, I did too, it is better to enter the properties of this file and set it as invisible.

    You will not be irritated by this file. It's there, but you can not see and there is no way that you can remove it somehow. Use this partition as usual. Create own folders, copy data here, just do your usual work.

    Any other questions?

  • Question about the management of data Cache OBIEE 10g / 11g.

    Hi friends,

    I have a question: how we can find the display of data in the report (in the answers or dashboard) if Cache or paintings of DW? y at - there no mechanism for this? I know that normally we can find data in tables of aggregation using file view log. Can you please help on this and I would really appreciate your help.

    Cheers!
    Srini

    Add the suggestions above, to find the query caches

    1. use followed - cache_ind_flg O/N indicates whether or not the application has reached the cache.
    2 NQQuery.log will show "cache hit" (if not you will see SQL to the physical database)

    There is no mechanism to track if it hits the browser cache / cache of presentation server.

    I hope this helps...

  • Questions about the management of the workbench versions

    I learned the hard way that we can't really use designer in workbench change forms, due to the increment of the version in each save and possible expansion of the database that could result.  Knowing this, the following questions come to mind:

    1. can I limit the number of versions of a form stored?
    2. can I clean old versions of a form?
    3. when I delete a form (or file) in the component resources, let's say it is at version 15, are all the previous versions of that deleted file too?  Or they hang out in the tables as orphans?

    If the answers to questions 1 and 2 are 'no', then I would really like to see a public service, perhaps /AdminUI, to treat it.

    Thank you!

    Elaine

    (2) how can we clean up older versions of a form in the system tables?  Would we need to directly manipulate the sys tables?

    Thanks to an API. Yes, hit the tables directly could cause significant problems.

    Through the API, you can query and report on resources in the repository, analyse resources and ultimately delete resources using deleteResources() with logical list of IDS (unique ID or ID). The API provides access to all resource metadata, you must commit resources to removing. See the resource class in com.adobe.repository.infomodel.bean

    (3) If you delete a file from the repository, and the previous versions are not removed automatically, then that helps sys table bloat,

    right?

    Altogether.

    On a note of similare, there is a purge tool supplied with the product to remove the long service life of the database process. The tools of purge is available

    2 - is the laptop DDR2 800 MHz, fragmented into several modules and is also able to run this speed? Standard is 667 MHz FAS so I know and maybe maximum.

    5. power outlet must be micro-479 with coupling balls, is that correct?

    Thanks for answesrs really knowing. :)

    Hi mate,

    I have almost the same machine, so I guess I can enlight you with my experience with this type of machine:

    1. No, unfortunately not, the second disc acts as a second HDD and nothing more. You can do software RAID which approximates longer than the share of your intention, but it s not the same as hardware RAID.
    2. no and Yes. No way to won´t CPU works with a higher frontsidebus but yes the modules work in the machine. I guess that the modules will be be underclockes at 667 Mhz to work with the designated CPU frontsidebus.
    3. If you have a SLI machine, you´re able to disable the second card.
    4 No, only the Celeron and the Core2Duo.
    5. Yes, the plug has 479 pin butwhat do you mean with ball coupling?

    Welcome them

    In addition, this machine is not a desktop computer... ;)

  • Satellite P10: Question about the limits of upgrade of RAM and HARD drive

    What are the limits to upgrade my laptop Satellite P10? Currently, I use 1 GB of RAM (2 x 512) and I still have the original 60 GB 4200 RPM HARD drive. I'm mainly interested in upgrading my hard drive to at least get a 7200 RPM 100 GB disc. Better would be one of the ones 24 hours server as Hitachi HTE721010G9AT00, I have just turned off my computer. Which one to take and are there limits (BIOS) (keeping in mind that there will be 200 and even the 250 GB drives next year)?

    RAM: should I put two 200pin SO-DIMM 333 or 533 or should not change at all as it works very well and stabil now?

    Hello

    In my eyes you should follow the guidance of Toshiba line and must use the memory modules that are recommended in the user guide. But if you can also try to test with 400 Mhz or 533 Mhz. I think that each dealer notebook or memory could do that.

    I think the BIOS might be able to handle the hard drive with capacity of 30 GB / 40 GB / 60 GB / 80 GB, Bus Master IDE with ultra DMA 100 synchronous
    In my opinion the BIOS does not recognize the larger HARD drive.
