• variable sharing, missing data, the timestamp even for two consecutively given

  Hello

  I have a problem with missing data when I read a published network shared variable.

  Host VI:

  In a host of VI on my laptop (HP with Windows XP Prof.) I write data to the shared Variable 'data '. Between two consecutively write operations is a minimum milliseconds of wait time. I use it because I want to make sure that the time stamp of each new value of data is different then a preview (variables shared the resolution is 1 ms)

  VI target:

  the VI target cRIO-9012 bed only of new data in the way that it compares the timestamp of a new value with the time stamp of the last value on a device in real time.

  Problem:

  rarely, I'm missing a data point (sometimes everything works fine for several hours, transfer thousands of data correctly above all of a sudden failure occurs). With a workaround, I'm able to catch the missing data. I discovered that the missing data have the timestamp exactly the same, then the last point of data read, is so ignored in my data 'legal '.

  To summarize, the missed value is written to the variable shared host, but ignores the target because its timestamp is wrong, respectively the same as the last value, despite the host waits for a minimum of 10 milliseconds each time before writing a new value.

  Note:

  The shared Variable is hosted on the laptop and configured using buffering.

  The example is simple only to display the function of principle, in real time, I also use a handshake and I guarantee that there is no sub - positive and negative.

  Simplified example:

  

  

  Question:

  Anyone has an idea why two consecutively data can have the same timestamp?

  Where timestamping (evil) Finally comes (System?)?

  What would be a possible solution (for the moment with shared Variables)?

  -> I tried to work around the problem with the clusters where each data gets a unique ID. It works but it is slower that comparing the timestamps and I could get performance problems.

  It would change anything when I animate the shared on the RT System Variable?

  Thanks for your help

• Fill in the missing dates with level

  Think im a bad thing. I have some data that missing dates (days) and I want to just fill in the missing days with 0

  This sql is to look right or I'm doing something wrong:

  SELECT H.URL, H.V_DT, NVL CNT (P.CNT, 0))

  SELECT CAL. URL, CAL. MIN_DATE + LEVEL AS V_DT OF)

  SELECT the url, MIN (D) MIN_DATE, max (D) MAX_DATE

  USER_LOG_TMP2_VW where the url is not null and current_url (select distinct URL of USER_LOG_TMP_VW)

  GROUP BY URL

  After MAX (D) > MIN (D)) CAL

  CONNECT IN CAL. MIN_DATE + LEVEL < CAL. MAX_DATE

  -GROUP BY URL, CAL. MIN_DATE + level

  ): LEFT JOIN USER_LOG_TMP2_VW P ON P.URL = H.URL AND F.F. = H.V_DT

  There are only about 75 unique URL and when I run the present it works but I can't count because there are so many lines when it should be, perhaps a few thousand. the oldest date of min goes back only a few months.

  im getting strange results. As if I add a specific url like this (below)... it works perfectly for this url. But when I go out as above where it captures all urls... it gives me weird super results. As the dates twice for duplicate URLS.

  SELECT H.URL, H.V_DT, NVL CNT (P.CNT, 0))

  SELECT CAL. URL, CAL. MIN_DATE + LEVEL AS V_DT OF)

  SELECT the url, MIN (D) MIN_DATE, max (D) MAX_DATE

  OF USER_LOG_TMP2_VW, where url is not null and current_url to (select url from USER_LOG_TMP_VW where url = 'http://testing123.com/test/test"")

  GROUP BY URL

  After MAX (D) > MIN (D)) CAL

  CONNECT IN CAL. MIN_DATE + LEVEL < CAL. MAX_DATE

  -GROUP BY URL, CAL. MIN_DATE + level

  ): LEFT JOIN USER_LOG_TMP2_VW P ON P.URL = H.URL AND F.F. = H.V_DT

  I was not post create it for the views with her but I think that maybe im just something wrong with the level.

  I tried the group according to the level of url cal.min_date +, but for some reason it just keeps running and the query never ends.

  Hello

  Depending on your needs and your version, you may want a CONNECT BY clause like this:

  CONNECT BY LEVEL< max_date="" +="" 1="" -="">

  AND PRIOR url = url

  AND PRIOR SYS_GUID () IS NOT NULL

• Missing dates in the table

  Hello
  
  I have a table that could have a record for the day with the sale of information, but for some reason, there are missing dates, is it somehow I could find the witch dates are missing.

  Sales_Date | value
  2010-01-01 | 20
  2010 01-02 | 30

• Creating a copy of the base data missing data UNDO files

  I need to create a copy of a database 11G on a windows server (using a script to create controlfile with database set = "database_name") from a cold backup that was taken at the time, but the backup lacks 2 3 of the UNDO tablespace data files.
  
  There is a lot of advice to suggest that setting undo_management = 'MANUAL' a database can be restarted and the missing data files dropped (and recreated)... However, I don't know if it is a solution that works in the context of rename the database by using create controlfile method
  
  does anyone know if the parameter undo_management = 'MANUAL' is all I have to do? or is it more...
  
  any suggestion would be received with gratitude...

  Dear patrichards,

  Your quite welcome. I am pleased that you have solved your problem.

• My imac (El Capitan 10.11.6 - 2 Terabyts) complete and FCPX disk will not work. I moved a few fcpxbundles library to an external hard drive (seagate 2 trabyte) and erased from the iMac. NowFCPX said that missing data as effects therefore can not shar

  Help!  My FCPX (v - 10.2.3) does not work because my iMac drive is full (iMac 21.5 inch has 2 terabyte w / v OS El Capitan 10.11.6) I had tried to free up space by moving tons of files on a usb disk Seagate (2 terabyte) speedboat that barely made a dent. then on the advice of a friend I found (in movies) a file called Final Cut backups. There were 4 files with extension, ".fcpbundle" I have three of them moved to another drive to Seagate usb - they had 2.82 GB, 21.6 GB and GB 68,21 that I thought should be enough and them removed from my iMac drive - bad! It says I have only 13.46 GB free on my 2 terabyte iMac total!

  The fourth fcpbundle it's TB 1.72! But before leaving that I returned and opened FCPX and found the warning triangle around my library... While my last project looked OK I couldn't / the share of exports because the pop-up says FCPX has no data for efx etc (the media looked at and display fine) and cannot be taken out.

  FCPX can work with the "beams" moved to another drive? How the detectable in a new place? Or how to put them back?
  How can I make sure that future packages clutter my iMac again?

  Do I need a RAID disks? If yes which?

  I found other folders in folders 'Make files' and records backup for projects with the .fcpbundle inside files

  How can I get this sucker working again?... and what should I do to keep him from doing the same thing in the future?

  Thank you

  :.. then on the advice of a friend I found a file called Final Cut backups (in movies). There were 4 files with extension, ".fcpbundle" I have three of them moved to another drive to Seagate usb - they had 2.82 GB, 21.6 GB and GB 68,21:

  The backup files are only the database files (no media) and must be low, not gigabytes, do not know what is happening there.

  Media libraries stored in the bundle of FCP X library or stored outside?

  If stored at the breast, called managed media, simply copy and paste the library to a different location.

  Make sure that library books newly located correctly before you remove what either.

  Perhaps check your settings of the library.

  Click the library icon in the browser and it appears in the Inspector:

  

  By clicking on change settings shows this:

  

  Move the mouse over the media and it will reveal the path where things are sent.

  Then you might be able to track down what goes where.

  From you description, it seems that most of the media files and rendered is not be moved successfully.

  Some screenshots would be useful if you can't find where stuff is.

• Point cloud with missing data and 3 sets of data

  Hello

  I'm doing a scatter diagram that has 3 sets of data in it (i.e. 3 plots on the same graph), except that 2 of my sets of data have a missing value while my third set has all the values. I end up getting 2 lines that are disconnected. I can't just remove the line containing the missing data for the 2 sets of data because since my category axis is time, my data points get shifted and no longer appear at the right time. This is the chart that I have.

  

  Thank you.

  Hi Gabrielle,.

  If there is a diagram of dispersion, the x axis is a value axis. If you have auto selected for the min and max values on this axis, the scale may change when you remove the data point, 15, 85, but the rest remains in the same position relative to the values on each axis of ordinates. What change will be , however, is the curve on which 15 85 approached a local y maximum.

  Scatterplots will always leave a gap in the line/curve of connection where there are a pair of missing data. There are two ways to close the gap.

  If the chart is an essentially linear relationship, you can use a calculated value is pair up with the lack of value x. The downside of this is that the representation of this point will be indistinguishable on the map of the other data points, measured.

  A better way would be to make two tables, one with the full data set, the other with the partial sets, but with the pair missing completely removed.

  Adjust the cards the same size and have the same scales on each axis, then just remove one of the cards except the data points, the curves connecting the data points, the x axis of ordinates and the legend showing the color and the forms used to plot each series.

  Give a graphic a transparent filling and place it in front of the other.

  Kind regards

• Missing data calendar after MS update

  This morning, I went to check my calendar in the Palm Desktop 6.2.2 and almost everything was missing. Apparently, an update of MS ran all night.

  In my Palm OS Desktop/username/calendar folder, I see a big (1408KO) file called datebook.bak and another called DateBook.mdb.bak (1464 KB) one who would contain my missing data?

  My last Coop diary is dated 10/08/09 and I wouldn't lose all my data from this date.

  Unfortunately, the restoration of data from my Palm TX is not an option.

  I am running Vista as the underlying operating system.

  Any ideas on the recovery of my lost calendar are appreciated.

  Hello

  The DateBook.mdb.bak file that you found contain your appointments before last successful hotsync. It would be important that hotsync not you your PDA or the bak file would have overwritten with the contents of the Agenda you see in Palm Desktop right now.

  I suggest that you undergo these:

  1. Create a new user name in Palm Desktop.
  2. While in the module calendar in the new user name, click file > import.
  3. Navigate to the location of the bak file.
  4. Type * (asterisk) in the 'filename' box and press ENTER. This should indicate the contents of the directory that the bak file.
  5. Now, double-click the bak said to import it.
  6. If you're lucky, you should see your lost appointments.

  If you're unlucky ignore the following steps:

  1. Now, are you sure that the bak file really contains your lost diary, near Palm Desktop.
  2. Using windows Explorer, navigate to your username folder. Usually, it's \Documents\Palm OS Desktop\ [a derivative of your hotsync username]
  3. Rename the folder "Calendar" to something else.
  4. Open Palm Desktop and be in your correct username and in the calendar module name.
  5. Now you can import the bak file in the folder of the Agenda that had renamed you in step 3.
  6. Now you can hotsync TX, but remember that the conduct of the Agenda is set to DESKTOP REPLACED the HANDHELD computer.

• Debug the 'Table function'

  Hello

  This question might be already on the forum, but I couldn't find anything about him.

  My question is: how to debug the service table.

  For example I have function in package

  Function Get_States (P_Parameter_1 In Number , P_Parameter_2 In Number ) Return Collection_type Pipelined ;
  

  And inside the function that I have piping line algorithms say some calculations. When I try to debug, it gives me error.

  

  Please guide me how to debug this function.

  Here, I found the solution.

  When I start debugging. It shows like this.

  

  So I just change

  DECLARE
    P_OWNER VARCHAR2(200);
    v_Return BIAS.DEBUG_TEST_PKG.T_PIPEROW;
  BEGIN
    P_OWNER := NULL;
  
      SELECT *
             bulk collect into v_Return
    FROM TABLE(DEBUG_TEST_PKG.DEBUG_PIPELINED_FUNCTION(
      P_OWNER
    ));
    /* Legacy output:
  DBMS_OUTPUT.PUT_LINE('v_Return = ' || v_Return);
  */
    --:v_Return := v_Return;
  --rollback;
  END;
  

  But before that, I noticed a few points.

  1 - whenever I update to the new version, I simply import preferences from the previous version (but this time, I DID NOT import. just do fresh install and configure the debugger on step.). I don't know but this import was somehow me gives error.

  2. just after the creation of new features in the package, it is not in the list of choices debugging functions, so I restart SQL developer.

  Thank you.

  Hello

  You can use UNION to combine the new lines that you generate using LAG or LEAD to actually the rows in the table:

  WITH new_rows AS

  (

  SELECT the point AS header1

  loc AS tete2

  Disc + 1 AS header3

  , ADVANCE (FEP) OVER (PARTITION BY point, loc

  ORDER BY eff

  ) - 1 AS header4

  FROM t1

  )

  SELECT *.

  OF new_rows

  WHERE header3<>

  UNION ALL

  SELECT the element, loc, eff, disc

  FROM t1

  --

  ORDER BY 1, 2, 3

  ;

  In any analytical function, there is never any point of order by the same expression that DIVIDE you BY.

• ORA-19612: datafile 0 not restored because of missing data

  Hello
  
  I'm testing a restoration of the controlfile. The database is in archivelog mode and automatic backup is defined on IT. I did successfully a full backup and backup of database copy.
  
  To test I did the following:
  -Note the DBID
  -closing of the database
  
  -Rename the two controlfiles:
  $ mv /u02/rcat/control01.ctl /u02/rcat/control01.ctl_old
  $ mv /u02/fra/rcat/control02.ctl /u02/fra/rcat/control02.ctl_old
  
  
  When I try to restore the controlfile autobackup form I get the following error. What could be reason please?

  Thank you!

  ORA-19612: datafile 0 not restored because of missing data

  lack of data---> file may damaged from backup sets...
  so try to take backup once more and then restore.

  In addition, you must give
  RMAN > list backup of controlfile; comes from the target database not new database...

  Thank you
