How to check the number of items available in RT FIFO?

Hello

Is there a way to check the number of items in RT FIFO without using READ FIFO function? I'm looking for a function like the function of status get queue VI.

Thank you very much!

Kind regards

Tom

    1. logically, it can not be followed from the point of view of database. Since when we migrated to new server we can just copy the data files and take the help of rman and migrate (hope you are aware)

    2. If we are not reset all the newspapers during the process, if we do it due to a problem we knew that the level of incarnation (date/time)

    3 database does not take care of these information

    4. perhaps there is an alternative, you can get it from 'DBA_HIST_DATABASE_INSTANCE '.

    that keeps INSTANCE_NAME and HOST_NAME... .When you database runs from host A for 6 months and then you moved to server 'B '.

    5 to start and next stop he will track this new server (provided during migration if you have made a rebound at this time, then you can have alteast moving day)

    6. IF you are looking for server then in the course of the interview you can bounce while patching so separate hostname is able to follow

    -Note - rest depends on the number of records that he takes for his life

  • How to check the number of "empty" field

    Hello world

    I describe the situation as a first step:

    • I work with WCC 11.1.1.5
    • I have workflows 5 steps.
    • Users can change the values of the attributes of document at each stage.
    • I managed the attribute is required in each step by rules. The attributes are not defined as ' required value: required ' by attribute definition. It is done by the definition of the rule.


    What I do:

    Check that one attribute (called xInv_SAP_document_line) has been filled in by the user in the third step of the workflow. This attribute is of type 'Integer '.


    What is my problem:

    Whenever the system performs the update of sending it automatically fills the number 0 for all integer attributes.

    When the user fills out a "xDepartment" attribute in the first stage, the system to insert a value of 0 for the attribute 'xInv_SAP_document_line '.

    I'm not able to verify if the user filled in the "xInv_SAP_document_line" attribute in the third step, because the value 0 is already there from the first step. It has no effect if the attribute is 'Required' - it has value = it's OK. But I need a control that the user fills out. Not the system.


    What I tried:

    'Use the default' check the box help doesn´t rule field. It only works for empty values.

    I can change the value of "derived field" checkbox in the second stage. But I'm not able to erase the value - what is the behavior I need.


    Is it possible to remedy this situation?


    Thanks for any advice,

    Mike




    Integer fields, once submitted, will be filled with 0 when the element is submitted and the field is empty.  It's the way integer fields work in Content Server - I've not seen a way to change this behavior.

    If 0 is never going to be a valid value, in the article "side effects" of the rule, add the following code and see if it solves your problem.

    <$if #active.xinv_sap_document_line="=" 0$="">

    <$dpPromote("xInv_SAP_document_line","")$>

    <$endif$>

  • How to change the number of items in number to Boolean, function VI table

    Hi, I'm working on using the digital output of data acquisition to control the digital input of a DAC, and I used the Number function in Boolean table. VI to convert the number to a Boolean array. The maximum number is 4096, so it must be composed of 12 elements.

    For the description of the VI, it is said that Boolean matrix returns a table of 8, 16, 32 or 64 elements, according to the number of bytes in the whole. Therefore, I change the number of channels in the task to 16, but it still does not work. The suggesitions are greatly appreciated.

    Thank you!

    Possible reasons:

    Scripture cannot be performed because the number of data channels does not match number of channels in the task.

    When writing, provide data for all channels in the task. You can also change the task so that it contains the same number of channels as the written data.

    Number of job channels: 12
    Number of data channels : 32

    Task name: _unnamedTask<1B>

    Once you have the array of Boolean, you can resize using table tools. For example you can use the "new range" with a length of 12 to pad the table of 12 elements of Boolean values (you can also use a subset of table).

  • How to find the number of data items in a file written with the ArryToFile function?

    I wrote a table of number in 2 groups of columns in a file using LabWindows/CVI ArrayToFile... Now, if I want to read the file with the FileToArray function so how do I know the number of items in the file. during the time of writing, I know how many elements array to write. But assume that I want the file to be read at a later time, then how to find the number of items in the file, so that I can read the exact number and present it. Thank you all

    Hello

    I start with the second question:

    bytes_read = ReadLine (file_handle, line_buffer, maximum_bytes);

    the second argument is the buffer to store the characters read, so it's an array of characters; It must be large enough to hold maximum_bytes the value NULL, if char [maximum_butes + 1]

    So, obviously the number of lines in your text tiles can be determined in a loop:

    Open the file

    lines = 0;

    While (ReadLine () > 0)

    {

    lines ++;

    }

    Close the file

    I have more clarification on the difference of connections and Sessions.

    Connection means a user process is successfully connected to the listener to have a session on the database running instance. (listener who listen s new connection requests)
    Establish sessions: means, a (dedicated) server process began to serve a user process. It is done when the credentials of the user authenticated successfully. Now, from process-user shall communicate to the server process directly.

    hope that helps.
