reads the data when I select run

When I insist on running my program reads the data from the meter power... when I'm not it gives me an error. I tried to put right waiting them etc and nothing seems to be set. Also, when I take the vi that read data from the electricity meter, the code runs much faster. I don't know if this has to do with global variables or what, but I just change a code supplied with this unit and it included global variables. I tried not to play with those yet. Anyway, if someone sees something that would eventually cure this problem please let me know. Thank you.

  • How to read the data with different XML schemas within the unique connection?

    • I have Oracle database 11g
    • I access it via JDBC: Slim, version 11.2.0.3, same as xdb.
    • I have several tables, each has an XMLType column, all based on patterns.
    • There are three XML schemas different registered in the DB
    • Maybe I need to read the XML data in multiple tables.
    • If all the XMLTypes have the same XML schema, there is no problem,
    • If patterns are different, the second reading will throw BindXMLException.
    • If I reset the connection between the readings of the XMLType column with different schemas, it works.

    The question is: How can I configure the driver, or the connection to be able to read the data with different XML schemas without resetting the connection (which is expensive).

    Code to get data from XMLType is the implementation of case study:

     1   ResultSet resultSet = statement.executeQuery( sql ) ; 
    2   String result = null ;
    3    while(resultSet.next()) {
    4   SQLXML sqlxml = resultSet.getSQLXML(1) ;
    5   result = sqlxml.getString() ;
    6   sqlxml.free();
    7   }
    8   resultSet.close();
    9    return result ;

    It turns out, that I needed to serialize the XML on the server and read it as BLOB. Like this:

     1    final Statement statement = connection.createStatement() ;  2    final String sql = String.format("select xmlserialize(content xml_content_column as blob encoding 'UTF-8') from %s where key='%s'", table, key ) ;  3   ResultSet resultSet = statement.executeQuery( sql ) ;  4   String result = null ;  5    while(resultSet.next()) {  6   Blob blob = resultSet.getBlob( 1 );  7   InputStream inputStream = blob.getBinaryStream();  8   result = new Scanner( inputStream ).useDelimiter( "\\A" ).next();  9   inputStream.close(); 10   blob.free(); 11   } 12   resultSet.close(); 13   statement.close(); 14  15   System.out.println( result ); 16    return result ; 17
    

    Then it works. Still, can't get it work with XMLType in resultset. On the customer XML unwrapping explodes trying to pass to another XML schema. JDBC/XDB problem?

  • How do I know the date when an oracle database is improved

    Hello

    I would like to know the date when an oracle database is upgraded (for example 10.2.0.4 to 11.2.0.3).

    Can you help me find these details.

    Thank you

    To be more precise, you can query

    Select to_char (ACTION_TIME,'MON-DD-YYYY ""), the SUBMISSIONS in ACTION, ID, VERSION, BUNDLE_SERIES, of DBA_REGISTRY_HISTORY where ACTION = 'upgrade ';

    Example:

    SQL > select to_char (ACTION_TIME,'MON-DD-YYYY ""), the SUBMISSIONS in ACTION, ID, VERSION, BUNDLE_SERIES, of DBA_REGISTRY_HISTORY where action = 'upgrade ';

  • I'm reading the data (speed rate and flow) of a table and it plot in a graph.

    I'm reading the data (speed rate and flow) of a table and it plot in a graph. I need to draw two values of l/min (speed) to the same speed. How can I do using a loop for?

    There is no need actually to use a loop FOR this. And using a graphic waveform isn't the type of field for this, for a waveform you a (Start), the dT T0 (greatness not) and table D (Data), this isn't what you want unless you know precisely the measure will take place according to an orderly disposal, you'd want a xy chart so that you can trace the measures where they occur in the axes X and Y of preference.

  • How to read the date of the day of the day of the year?

    I want to put 30 days for the test of endurance for the application of the components. the user will have the current value of 30 days with specify them the end of the day.

    I saw that the "seconds to Date/Time.vi" sure I checked the day of the year. If I can use this day of the year, I can add + 30 read 30 date.

    Barros,

    What I gave was the answer you were looking for originally because I believe.  You will not just be able to read the date in a coherent way and then add 30.  You can either use the function Get time in seconds or a few varaint it and then add the offset you want (you could use the get a Date/time string and enter the date directly, but this digital conversion which will be useful in the monitoring of the time elapsed will be much more difficult than what I provided only).  If you want to stop the test, simply to keep track of the amount of time the test is in pause and extension at the time where that amount.

    That's what the doc says:

  • How to read the data written to the virtual disk

    I use the following VDDK function to read the Flash disk from VMware

    http://bigchainring.kicks-ass.NET/functions/VixDiskLib_Read.html

    But areas of complete disc playback, including empty spaces. I need to back up only the data written to the Flash disk. It is to save the backup disk space (for example if 126 instant KB is written in 40 GB of disk snapshot, then we read only 126 KB and not 40 GB drive). Please suggest the correct way to read the data written to the Flash disk as well as to reproduce the same virtual disk with the data.

    VMware vSphere API queryChangedDiskAreas() can be used to obtain the data blocks in the virtual disk.

    Steps to follow:

    1. get the beaches of block of data (numbers) using queryChangedDiskAreas() API with '*' as argument.

    2 read the data of the specific blocks by using VixDiskLib_Read()

    3. write to another drive using VixDiskLib_Write()
