• A tutorial / sample to create a single PDF of several source files using assembler PDF in a process of control folder.

  A tutorial / sample to create a single PDF of several source files using assembler PDF in a process of control folder. I have a client application that will prepare the number of source files and metadata information (in. (XML) that will be used in the header/footer. Is it possible to set a run time generated shows the DDX file in the folder and use it in the process. If possible how can I pass the file names in the DDX. Any sample process will be very useful.

  If possible, make use of the API of the assembler in your client application instead of doing this using watched folder. Here are examples of the assembler: LiveCycle ES2.5 * programming with LiveCycle ES2.5

  The record can accept zip files (example: configuration of a control folder to manage several input files and write the results to a single folder |) Adobe LiveCycle Blog ). You can also use run the script to create the DDX when executing: LiveCycle ES2 * Application Development using LiveCycle Workbench ES2

• HAVE high sampling frequency of trigger

  Dear community

  I am using a microscope to tunnel effect from here feeding two voltage signals on my map of acquisition of data USB-6212 (Labview 2013 SP1). A voltage signal is the voltage applied to a piezo in the microscope (AI0). This signal drifting slowly over time and it is noisy. The other voltage signal is a tunnel current is converted into a voltage (AI2) signal (see attached photo):

  Ideally, I would like to record the two signals between the lines dotted in a .txt file whenever the event of tip in the top image rises. This should be about every second during a day.

  So far, I've written a VI that calculates the moving average of the piezo signal and if the piezo voltage exceeds a certain percentage of the average running it fires a command 'Save as file'. The VI works well for a frequency of 100 Hz, but when I go to 20 kHz, the trigger does not work properly. I am also only watching a lot of a number (in this case, 1000) and if there is a trigger signal in these samples of 1000. So if there's a signal around 0 or 1000 I cut and split into two files that I want to avoid.

  I don't have much experience with Labview and probably broke every rule of design in the book.

  My question is if there is a smarter way to automatically back up the signal between the same dotted lines at high frequencies of sampling?

  I thank very you much in advance!

  Hi Mario,.

  I rewrote the portions of your VI to improve performance (we hope). No need to three queues.  No inquiry unless there is a trigger occurs.

  I'm confused by the outbreak that seems to detect the edges of the piezo signal high side, even if the tip is in the negative sense.  I modified this logic (eventually) get a threshold top-side of the signal of tunneling.

  It is unclear what might happen to 20 kHz.  The example shows a constant 1 kHz sampling rate and 1 K samples treated by loop.  If the sampling rate is changed to 20 kHz, then the loop will have to run to 20 Hz in order to keep up with the acquired data (@1 K samples per read).

  I hope that the joint allows VI (not tested).

  Your information is good enough about the use of roles. This is the model of security that our customers use. Only assign us a password for roles and issues of connection of users shape the grant sql role using the password is used since in the form.

  However, I agree with Andreas on the hard coding schema owner. We have several clients, and each of them has a different name for the owner of the schema. By creating a public synonym for access to our forms tables, our forms work well at all sites.

• Finite sampling on each trigger

  Hello? I have a problem of error about DAQmxSetReadOffset().

  Whenever I put this code,

  short* DataBuffer = new short[_countof(dbuffer)];
  ...
  DAQmxErrChk (DAQmxCfgSampClkTiming(taskHandle,"",fRate,DAQmx_Val_Rising,DAQmx_Val_FiniteSamps,_countof(dbuffer) ));
  ...
  

  I get this error:

  

  _countof (dbuffer) is a data buffer size. I wish to acquire _countof (dbuffer) sample size.

  I tried this, but no use.

  DAQmxErrChk (DAQmxGetReadAvailSampPerChan(taskHandle,&reading)); 
  
  if(reading>_countof(dbuffer))
  {
  DAQmxErrChk(DAQmxSetReadRelativeTo(taskHandle,  DAQmx_Val_MostRecentSamp ));
  DAQmxErrChk(DAQmxSetReadOffset(taskHandle, -(_countof(dbuffer)) ));
  }
  

  Ah, I solved the problem. He used a while() condition, but it causes this error.

  Continuous sampling must while() but in this case, it didn't need it.

• How can I create a single delayed output (analog voltage) of a Trigger (analog voltage) input reference pulse?

  I am working with a combustion chamber and using a system of data acquisition (with the hardware OR SCB - 68) to read the pressure in the cylinder (such as analog voltage). I'm trying a pulse delayed, 1 millisecond to 5 volts of output once the pressure in the cylinder is high above 5 bar (which corresponds to an analogue voltage of 0.25 V). I would also like to record 30 ms samples before the trigger and 220 ms samples after the outbreak. The following image shows visually what I'm talking about.

  I created a LabVIEW VI (which is attached), but I keep running into 2 issues:

  1. When I run with samples finished after a period of time, I get error-200281which I don't quite understand.
  
  
  2. Using the Express VI 'Out of time' to keep time for the pulse I can not get a resolution of 1 millisecond, the pulse is not generated when I put the window between 0.003 and 0.004 seconds for high pulse (i.e. the resolution of 'Elapsed Time' seems to be too coarse).

  I'm a beginner to LabVIEW sorry if my questions are trivial or my VI makes no sense, but I was stuck on this during more than a week. Any help would be greatly appreciated!

  Thank you

  Morgen

  This isn't a good way to trigger a pulse.
  Use a trigger DAQmx to send the pulse when your acquired signal exceeds 250 mV you specified.

  See this for DAQmx trigger:

• Use of "DBA_OBJECTS" in 'CREATE AFTER' Trigger

  Hello
  
  We want to store additional information about our items, we have in the database. Do we tought of the idea of creating a "documentation" table containing an object_id that references to the object_id of the dba_views view.
  
  Now we want to create a new record automatically in our table documenting when a new object is created, as a first step it should contain only the object_id
  To do this, we use a "AFTER CREATING" trigger, but when this trigger is enabled and if the code finds the new object_id in dba_objects, he returned no records and generates an error. Probably because when the trigger is run, the display is not yet updated?

• Help me in creating a trigger Insert and Update Options

  Hello
  
  Please help me in creating a trigger.
  
  My requirement is that, after insert or update on a Table, I want to launch an event.
  
  I have started this way, but does not know how to fully implement it.
  
  I have a dept table
  
  
  CREATE TRIGGER DepartmentTrigger
  INSERT AFTER on Dept
  BEGIN
  INSERT INTO mytable VALUES("123","Kiran");
  END DepartmentTrigger;
  
  
  Please tell me how I can put the update option also.
  
  Thanks in advance.

  Please tell me how I can put the update option also.

  Add "or update". ;-)

  Here are a few suggestions, but you definitely need to refer to the manual page that suggested the previous poster.

  CREATE OR REPLACE the TRIGGER DepartmentTrigger
  AFTER INSERT or Update ON Dept
  BEGIN
  INSERT INTO mytable VALUES(:new.) Dept 'DEPT ADDED OR CHANGED');
  END DepartmentTrigger;

  The "or replace" means that you can replace the shutter button as you develop without having to type in a drop statement each time. Just change and reissue your script over and over again until you get it right.

  The addition of "update or" or "Or remove" fact the trigger too much fire for these events. Note, you peut want separate triggers in different scripts and with different names for each event. You must decide whether your design is really the same thing either an insert or an update.

  : new. Dept, this is how you should refer to the vale has changed the Dept column (: old.) Dept is the previous value). I changed the double quotes in the string in the clause VALUES of apostrophes.

• You want to capture update dates, with trigger on a view to refresh quickly materialized. But trigger on MV consider inserting and updates are inserts only.

  So, if check you my code,.

  When I insert EF = SYSDATE, IJ = SYSDATE.

  Update EF is not changed, IJ = SYSDATE.

  So I like to capture their insertion and update dates.

  But if updates or insert arrives on the materialized table. The trigger themselves as an INSERT only.

  So how do you capture the updates?

  I use the statemnet with out merger with performance and also able to capture the update dates.

  CREATE OR REPLACE TRIGGER test1_trig_merge

  AFTER INSERT OR UPDATE OR DELETE

  ON test1_v

  FOR EACH LINE

  DECLARE

  lr_test2 test2% ROWTYPE;

  lv_error VARCHAR2 (4000);

  BEGIN

  IF THE REMOVAL

  THEN

  DELETE FROM test2

      AB = WHERE: old.a;

  ELSIF INSERTION

  THEN

  MERGE INTO test2 one

  B using (SELECT 1 FROM DUAL)

  WE (ab =: new.a)

  WHEN MATCHED

  THEN

  UPDATE the VALUE ab =: NEW.a.

• Essbase Studio impossible to 'Examining the sample data' in the Oracle DB Data Source

  E.M.P. version 11.1.2.3.500

  Oracle DB 11.2.0.4

  on Windows 2008R2

  I created a user DB ESSTBC with the following user privileges

  CREATE SESSION, CREATE TABLE, CREATE TRIGGER, CREATE TYPE, CREATE VIEW

  This is my first attempt on the Essbase Studio, so I executed the following scripts as the user ESSTBC to create the TBC tables and load the data

  tbc_create_oracle. SQL

  tbc_sampledata. SQL

  I am able to connect with ESSTBC and select the tables all loaded and made sure the data is loaded correctly

  Then in the Studio of Essbase, I created a data source, which I can list all the tables in the schema ESSTBC in 'Data Source Navigator'. I also managed to create a Minischema by joining the tables SALES, SCENARIO, and MEASURES.

  However, in "Data Source Navigator" when I select "SCENARIO", right click and select "View Sample Data", I am able to pull data from the table. that is the table with all the names of columns grid but no data. No error messages were shown in "Messages to the Console.

  Back to Developer SQL and connect the same DB as ESSTBC, I have no problem do a "SELECT * SCRIPT;" and recover all the data of the table without a problem.

  I proceed creating dimensions elements then a hierarchy of "SCENARIO". But again when I try to get a glimpse of the hierarchy has got an empty tree. Apparently, there's something wrong,

  No matter what mark on what I missed?

  Thank you very much.

  Problem solved. The cause being my stupidity ruin a access DB. I can see examples of data without changing anything in Essbase Studio after you change the DB user rights.

• Trigger errors

  Hi guys,.
  
  Im very new to sql and oracle. and im trying to create a trigger - but unfortunately its not okay! Here is my code
  
  
  CREATE OR REPLACE TRIGGER "SHOP_ERRORS".
  Before you INSERT or update on the SHOP current_status
  BEGIN
  Select current_status in the STORE
  of the new. SHOP_id SHOP_id =
  
  IF (shop_status = ("CLOSED")) THEN
  RAISE_APPLICATION_ERROR)
  NUM = >-20000,
  Msg = > "Cannot reopen a trade union monopoly");
  
  
  END IF;
  END;
  
  IM basically trying to check when a user adds a new log entry for the shop that they do not try to reopen a store that is closed. and im getting the following errors
  
  5 7 PL/SQL: ORA-00933: SQL not correctly completed command
  2 1 PL/SQL: statement ignored
  11 11 PLS-00103: encountered the symbol "IF" when expecting one of the following numbers: ///this is followed by a random string of operators
  
  
  any help would be appricaited, I know this may be totally wrong - but I read and research on the triggers in the extent possible and im still stuck!
  
  Thanks in advance

  Well, if you do not want to change the structure of the DB and want to handle this programmatically, then you will need to reproduce the functionality of trigger manually:

  A sample:

  create or replace Function MANUAL_TRIGGER(p_shop_id IN varchar2) return number is
  
  v_shop_id shop.shop_id%type;
  v_status shop_log.current_status%type;
  
  Begin
  
  select shop_id into v_shop_id from SHOP where shop_id = p_shop_id FOR UPDATE WAIT 1;
  
  select current_status into v_status from SHOP_LOG where shop_id = p_shop_id and date_time =
      (select max(date_time) from SHOP_LOG where shop_id = p_shop_id);
  
  if upper(v_status) = 'CLOSED' then
      rollback;
      return 0;
  else
      insert into shop_log (log_id,......) values (.........);
      commit;
      return 1;
  end if;
  
  EXCEPTION
      when others then
           rollback;
           return 0;
  End MANUAL_TRIGGER;
  

  Explanation:
  Assuming SHOP_ID's PK in the table in the SHOP, the function creates a lock of line over the COUNTER for the SHOP_ID for which he's updated status.
  -Lock line
  -Check the latest status
  -If the status is closed, then rollback to release the lock and return with the error (0 return)
  -If the State is not closed, then insert the record in SHOP_LOG and agree to release the lock and return with success (1 return)

  In the calling function, use the values returned by the function above to check the conditions of success and mistakes and act accordingly.

  It is just a code example and not fully tested ready to the use of code, so please edit according to your needs.

  I hope this helps.

  Kind regards
