Access to the new data in Event Message user callback?

I use the Simple OI LabVIEW as a template for my user interface for TestStand.

The sequence sends a Message to the user to the IO to the string array of tests to run.

But I'm having a lot of difficulties this string data in table for the VI event reminder.

I don't want to use a global variable and so my method without success so far has been as follows:

1. use a Refnum at the matrix and pass in the event reminders VI through the cluster Config

2. the "selected Tests" in the entry in the Config cluster event reminders VI is a generic control Refnum

3. the selected Tests (below) is then delivered and passed in the User parameter

4 but how to convert the refnum control Tests that are selected in the original array of strings in the real callback?

???????

Also if there is someone who can suggest a better way to do this then please let me know.

The line at the bottom is - how to get the most recent data in the event callback function when it is called?

Thank you very much

Ronnie

Ultimately to get this working, I gave up on the string table and changed to a ListBox instead. It was easy then to access the properties of the listbox through the refnum. Probably a major flaw in my understanding of how string refnum work tables.

  • Migration Oracle RAC to the new data center

    Hi all

    We are 'legacy' Oracle 11 G RAC cluster from another company and I am looking for a way to migrate with the minimum of downtime. Our team has no CARS, nor database administrator Oracle also experience.

    We intend to test the migration by cloning the environment a few weeks before and just see if everything is OK.

    Question is, what is the best way to migrate this RAC cluster and it's data to a new data center? Reinstallation of the operating system (Linux) and recreate the RAC cluster are not an option I want to examine.

    For example, in the land of SQL Server, we can use sending newspapers or replication to keep a copy of the database in the new data center as close as possible direct database (data-wise). Date of commissioning, we stop the direct instance, run last restore log or something else, then set up the databases on the new data center.

    Thanks in advance.

    Data Guard. It is the name of "log shipping" feature Oracle. It's probably closer to always on SQL Server availability groups, except that the Oracle database is a large group.

    I speak not Active Data Guard which is an extra cost that gives options on top of Data Guard.

    HTH,

  • Copy of VM to the new data store

    I need to copy an existing virtual machine to one datatstore to the other, initially, I thought that I would be able to register to the VM, clone the virtual machine and then unregister the virtual machine.

    Unfortunately the VM I will be copying is the virtual Center VM and therefore this action must be carried out while it is connected to a host and cloning is a feature of VC.

    Is the best method to use the New-TkeDatastoreDirectory and TkeDatastoreFile-copy to copy these through to the new data store?  I think I read earlier that it does not work or is very slow for large VMDK files?

    Thank you

    Bruce

    The application data folder is just a re - direct to the new version of the short name.  It is only there for compatibility, and since he is not a real file, you cannot open it.

    To get the files you want, you must do this:

  • Access the views Where the access to the underlying data, through a role

    I have a user (say User1) who granted select access to motherlode via a role table

    User1 has a bunch of useful views created I want User2 to have access to the. User2 should have access only to these points of view, not to the underlying table.

    User1 can grant access to his point of view because it has no direct access granted to motherlode tables.

    I managed, based on a technique that I have for the most part, but do not entirely understand, give User2 access to data through a function. The solution is below.

    My general question is: y at - it an easier way (other than the grant direct access to the motherlode User1 tables)?

    My question is: the definition is possible shorter somehow. I know I can automate the production of the code for some of the statements using metadata, but, for example, is it possible to base the declaration of type (t_p5) on the existing view? (I have about 15 views I need to provide access)

    Solution is, where v_p5 is the original view:

    User 1:

    CREATE or replace type t_p5 as an object

    (< columns and data types of v_p5 >

    )  ;

    CREATE or REPLACE TYPE t_p5_tab AS TABLE OF THE t_p5;

    FUNCTION to CREATE or REPLACE f_provide_p5 RETURN t_p5_tab

    PIPELINED IS

    l_cur SYS_REFCURSOR;

    l_rec v_p5% rowtype;

    BEGIN

    L_cur OPEN FOR ' SELECT * FROM v_p5';

    LOOP

    EXTRACTION l_cur

    IN l_rec;

    EXIT WHEN l_cur % NOTFOUND;

    GUIDELINE (t_p5 (area = > l_rec.region))

    , district_name = > l_rec.district_name

    , current_month = > l_rec.current_month

    , p_current = > l_rec.p_current

    , previous_month = > l_rec.previous_month

    , p_prev = > l_rec.p_prev

    , diffp = > l_rec.diffp

    , diff_perc = > l_rec.diff_perc

    , previous_year = > l_rec.previous_year

    , p_year = > l_rec.p_year

    , diffy = > l_rec.diffy

    , perc_diffy = > l_rec.perc_diffy

    ));

    END LOOP;

    RETURN;

    EXCEPTION

    WHILE OTHERS THEN

    raise_application_error (-20000, SQLERRM |) Chr (10) | l_sql);

    END;

    And user2:

    VIEW to CREATE or REPLACE v_p5 AS

    SELECT * FROM TABLE (User1.f_provide_p5);

    I can then do a select * from v_p5 in User2 and return the view data.

    Thank you.

    Hello

    Don't bother with the pipeline and PL/SQL functions.  Everything will be easier, more effective and more reliable if you use only views.

    Privileges through roles do not create a view on a table in another schema.

    If user1 can create a view on motherlode.table_x, then user1 should have direct privileges already (or user1 must have a privilege of system as SELECT ANY TABLE).

    User1 needs the same privileges WITH GRANT OPTION in order to grant privileges on his point of view to User2.  To do this, have motherlode grant privileges to user1, like this:

    GRANT SELECT ON table_x to User1 WITH GRANT OPTION;

    GRANT SELECT ON table_y to User1 WITH GRANT OPTION;

    Repeat for each table that user1 uses in the views.

    Then user1 will be able to grant privileges on views to User2 like this:

    GRANT SELECT ON my_view_01 TO user2.

    This will NOT allow user2 directly see the motherlode.table_x.  User1 will have the power to give privileges to User2, but simply grant privileges on the view does not give User2 these privileges.

    If you don't want User1 to have this power, then create the views in the motherlode scheme, or create a new schema only for the putpose to own these views.

  • How to migrate Office persistent link clones of workstations for the new data store

    Hello. We have clones of persistent link to view running in the environment from our view. We need to migrate these desktops to new storage. Rebalancing is out as this will include a refresh operation - destroy anything and everything installed in c:\ of the user. Is there a method to migrate Desktop clone link persistent to a new data store, while keeping the office in the same exact state (i.e. c:\ is not updated).

    Thank you

    Never say impossible. I came across the solution when I read the article by Duncan Epping:

    http://www.yellow-bricks.com/2012/03/15/Dr-of-view-persistent-linked-clone-desktops/

    I have that for my situation. Basically, replicate data from view in the new storage warehouses. Set up data warehouses replicated without re-signing with the cluster of ESXi. Turn the power off and unsubscribe the vCenter view workstations. Save the workstations from the data store replicated/mounted to vCenter and power over desktop computers.

    VCenter, nothing dramatic has happened if she sees just as vm being unregistered and re-recorded activity from the same exact data store (the same UUID). View Admin is happy because he sees just the events as desktop computers that have been turned off and then subsequently in reverse. Nothing has changed regarding the database to view ADAM, we still use the same data warehouses.

    I have already tested before for a scenario of View DR, and he succeeded. Between remembering who and Duncan's article helped me to adapt the same process for this. Nothing is impossible

  • Failed to get the disk partition information when you add the new data store

    Hello

    Update my ESX to version 4 Update 1 (4.0.0, 256968). Now, I'm trying to add a new data store to a cluster in vCenter and receive the following error message when I will review the current structure of the disc "error when configuring the host: failed to get the disk partition information. When I click back, then next, there's no error message but in the formatting window, I get the error "Object reference" not set to an instance of an object.

    I see this question has been asked before, but I can't seem to find an appropriate response. Anyone? The interface using CLI instead of vCenter isn't an option (alignment VMFS, workload and so on)

    The size of the LUN I want to add is 741 GB

    Concerning

    Marius Aulie

    If you have a virtual machine for Windows test, you could do the following, to ensure that the logic unit number has a clean partition table:

    -set the LUN as a GROSS physical to virtual machine device

    -Run diskpart, select the drive and run the CLEAN command

    -detach the LUN to the virtual machine

    -try to create the data on the LUN VMFS store

    The size of the block of the data store where the VM test can be a problem with the above. Due to the size of the LUN, the size of the block of the data store must be at least 4 MB. Attach the LUN to a physical test system could be an alternative.

    There will be a cut-over on the last weekend.

    Concerning

    John

    You can use something like veeam vSphere replication to copy virtual machines to the other site and then just turn the 'old' off the coast and the new ones on. Your biggest problem will be changing hosts. Only other option might be to physically move the old hardware to the new site. Persistent drives will be a pain. I would like to have more useful for you answers.

  • ESXI 5.1 "the disc is not thin-provisioned" after copying to the new data store vmdk

    I wanted to create an external backup as a 2nd VM ready-to-run on the 2nd data store.

    I've removed all snapshots, stop the machine virtual and exported the OVF file to a computer, adjusted to the size of the original virtual machine starts in Gparted to update the partition and restart. All very well.

    I then tried to deploy the OVF in the data store alternative (235GB slim, thickness according to the deployment of 250 Wizard). I tried both thick and thin but the error message "cannot deploy the OVF. The operation was cancelled by the user.

    I then manually downloaded the VMDK & OVF file to the 2nd data store and tried to inflate but then received the message "a specified parameter was not correct. The disc isn't thin provisioned. ».

    It seems I have dealing with the same thing, as this is the document here (http://pubs.vmware.com/Release_Notes/en/vsphere/55/vsphere-vcenter-server-55u3-release-notes.html).  However, I have no idea what to do now... and I'm worried because it seems that my backup plan may not work if I can't restore an OVF/VMDK from a disk of visas.

    The solution to the first problem here: https://communities.vmware.com/message/2172950#2172950 that solved my problem 2nd too.
