• Work Dbma_scheduler execution of procedure which loops through all the customer drawings in the rear rollers database transaction in case of exception

  Hello

  Need your contributions on the approach to implement a work using dbms_scheduler.

  We have about 2000 drawings. Each schema has a package with 2 procedures.

  The requirement is to create a single job in SYS that loop over each schema and run the procedures specific to a time (once a day) and send a notification by e-mail on success or failure.

  Working script:

  BEGIN

  dbms_scheduler.create_job (job_name = > 'LOAD_EACH_SCHEMA_AUDIT_DATA',)

  job_type = > 'PLSQL_BLOCK ',.

  job_action = > ' BEGIN sys.p_loadaudit;

  END;',

  start_date = > systimestamp,

  repeat_interval = > ' FREQ = MINUTELY; RANGE = 1',

  number_of_arguments = > 0,

  enabled = > true,

  Comments = > "Use repeat interval is every five minutes");

  END;

  /

  Note: to test the end I put him repeat interval to carefully.

  Use of procedure must be running:

  Procedure sys.p_loadaudit:

  CREATE OR REPLACE

  PROCEDURE p_loadaudit

  AS

  v_count NUMBER: = 0;

  lv_error_message VARCHAR2 (4000);

  vstmt VARCHAR2 (4000);

  BEGIN

  I'm IN

  (SELECT username FROM dba_users WHERE username LIKE '% ABCFIRM')

  )

  LOOP

  vstmt: = "begin" | i.UserName | '. pkg_audit_info.p_load_coa; end;';

  EXECUTE immediate vstmt;

  vstmt: = "begin" | i.UserName | '. pkg_audit_info.p_load_am; end;';

  EXECUTE immediate vstmt;

  END LOOP;

  END p_load_AM;

  END pkg_audit_info;

  /

  Table1 and table1 exist in schema_01.

  All 2000 patterns have same package.procedures.

  For security reasons, I removed the actual code.

  I was able to complete the task successfully. However, when a scheme procedure (SCHEMA_01.pkg_audit_info.p_load_COA) throws an exception, the job fails, and any transaction is rolled back.

  Is it possible to loop through each schema and run the corresponding procedures. Even if the exception occurs, it must restore only for this scheme and continue other patterns in the loop?

  Please let me know if there is a better way to do this. Is the way I'm handling exceptions in the work or the correct procedure?

  Thank you

  Hello

  RAISE_APPLICATION_ERROR will cause the program to exit to the appellant, even if you put it inside a block in the loop, so the statement RAISE or RAISE_APPLICATION_ERROR must be placed in your procedures 'pkg_audit_info.p_load_AM' and 'pkg_audit_info.p_load_coa '. In this way, you can use a block inside the loop and the error in the log.

  I'm IN

  (SELECT username FROM dba_users WHERE username LIKE '% ABCFIRM')

  )

  LOOP

  BEGIN

  vstmt: = "begin" | i.UserName | '. pkg_audit_info.p_load_coa; end;';

  EXECUTE immediate vstmt;

  vstmt: = "begin" | i.UserName | '. pkg_audit_info.p_load_am; end;';

  EXECUTE immediate vstmt;

  WHILE OTHERS THEN

  --> Set the error in a table of otherwise custom event log you won't know what happened for this scheme: don't forget the user name

• Two questions in table "While loop"

  Hello

  I have two questions about creating tables in while loops. I'm using LabView 8.5.1.

  In its simplest form, my current while loop (delay set to 0, 2 s) has 3 variables that have been changed by moving a slider. They are each sent to a line in a block of 'Building the table' (data type is DBL 1 d) - this table is then written to a spreadsheet file, such as the three values are written to a new line (one value per column) whenever the while loop runs.

  Question 1

  How can I add a column 'Time' in this worksheet? In other words, get at the present time the loop works since then, from 0 seconds in the spreadsheet, via the table block building.

  I can think of how to do this with a loop For, but given that the While loop runs through an unknown number of iterations, I can't figure out how to get the counter to work.

  Question 2

  How can I text column headings on the worksheet?

  Thanks for the help and if you need anything anyone stating, please let me know

  To answer question 1:

  There is a function of 'Elapsed Time' you can put as the first colum of the data.

  This then reformatted your spreadsheet as
  Time Data1 Data2 Data3

  Time Data1 Data2 Data3

  Time Data1 Data2 Data3

  etc...

  

  To answer question 2:

  Build a table of positions, then write this table in the file only once, outside the loop.

  Your table with the data and time will write inside the loop.

  

• Question of architecture / chained loops

  Hey guys,.

  So, I got a quick question on the loops of producer/consumer.

  I have a DAQ loop which I am trying to control - i.e. when to acquire data or when to go to the "idle" mode.

  At some point I want to acquire data at all times, while at another time, I want to stop and go to the "idle" mode.

  I was wondering what is the best way to to do.

  My outer loop should he send the Canadian signal and period of time later (1 or 2 seconds) will send a signal to stop, again, another signal of departure.

  1. use a notifier that sends a Notification of Cluster (option + command)--> containing some settings I need to acquire-the command 'acquire '.

  2. enter this notifier with Notification of Signal waiting

  --> This to enter the State to acquire

  3 return the same identical notification making a loop.

  OR

  1. use a notifier that sends a Notification of Cluster (option + command)--> containing some settings I need to acquire-the command 'acquire '.

  2. observe notifications with a function of State notifying get. When the declaring State changes to acquire, it will always acquire and where another notification is sent (stop) then the State will change.

  The other seems like the obvious solution, but I wonder if there are any reservations-c.-d. race conditions general/warnings warning do not use the service to get notification...

  Am not too familiar with some of the strange scenarios and me have already been screwed by Notifications jump some orders before - it was boring hard haha

  Or actually... If you have any other suggestions on how to make this architecture works, I'm all ears.

• Simple question: timed period while loops

  Hello

  I have a timed loop, and if the user presses a button "repeat" loop runs until 'repeat' is set to false. I want the loop to iterate over a given period, including user input. Inside the loop, a square wave pulse is created based on the parameters provided by the user, then displayed on a waveform graph.

  However, when I change some of the initial settings of the square wave, for example from tension, the waveform graph is updated instantly. I want the waveform graph only be updated based on the period provided by the user, all say a second. I tried to set the period of entry into different amounts of 10000 a.0001, but always updated at the same time waveform graph.

  I'm not sure what I'm missing, but I'm sure it's something trivial. My VI is attached. Any help will be appreciated.

  I don't understand what your problem is.

  If I run your VI (and hit the repeat button firstly, otherwise VI blink tracks then stops) and make changes to tensions, duration or delay, it will take a little time or a lot of time according to the what is the length of the loop, and where I do the modification to controls during the delay of the loop.

  (With a period of 5000 milliseconds, a change can take up to 5 seconds to show in the event where you make the change right after the beginning of the loop.)  «(Or it may take a fraction of a second if you make the change just before the loop iteration ends).»

  Maybe you can give us a configuration of the parameters, we should enter each controls (even better puts these settings yourself, do the default values, and then save the VI before posting) as well as specific guidance on what we should do to recreate all that is your problem.

• Question about layers and loops!

  Hey guys,.

  I am a newbie and I hope I can explain this scenario properly.

  Basically, I create a banner in Flash 8 Pro, graphic designs previous.     It consists of a backdrop, a 4 frame logo and the text I want to sweep in on the left hand side on 20% of the banner.

  Now! ... is there a way to create a layer to have this text appear on and stop at a desired position, while the main logo covers the 4 frames continuously?   (I had a go, but everything seems to work, in other words, the same steam - no separate command)

  Hope that is more clear as mud?

  All the best,

  CAL

  Hi Cal,

  Or you can create a movieclip (F8) and place your 4 images of logo in this movieclip.

  Then in Scene1 you can place the movieclip on layer logo and on a separate layer have your text flying in animation.

  One thing to remember to do this way is to make sure that your film has enough frames to account for multiples of four, other wise your logo will look like its onece jump the playhead in loop at the beginning.

  Hope that makes sense

  Hi John,.

  It's funny he is actually a very good example of what you're trying to do in the doc IDOC Schema section.

  Here it is:

  <$getViewValuesResultSet("Country_View", "",="" "")$="">
  <$loop schemadata$="">
  <$count =="" 0,="" num="rsNumFields(" schemadata")$"="">
  <$loopwhile count="">< num$="">
  <$fieldName=rsFieldByIndex("SchemaData", count)$="">
  <$fieldName$>=<$getValue("SchemaData", fieldname)$="">
  <$count =="" count="" +="" 1$="">
  <$endloop$>
  <$endloop$>

  With a doc info it would look more like fine.

  <$dID="12345"$>
  <$executeService("DOC_INFO")$>
  <$loop doc_info$="">
  <$count =="" 0,="" num="rsNumFields(" doc_info")$"="">
  <$loopwhile count="">< num$="">
  <$fieldName=rsFieldByIndex("DOC_INFO", count)$="">
  <$fieldValue$>=<$getValue("DOC_INFO", fieldname)$="">
  <$count =="" count="" +="" 1$="">
  Field name:<$fieldName$>
  Field value:<$fieldValue$>
  <$endloop$>
  <$endloop$>

• Synchronize with looping background

  Hello

  I'm doing 2d side view car animation.i have a background loop composition. Sometimes my car has to overcome obstacles on the road.and I cannot do a real synchronization between the compositions of the loop road and objects on the road.i cannot put objetcs open-ended know.how looping you can provide sync them together?

  the second question is have background looping and looping the wheels if I want to stop the animation I use the case expression, but when I want to start that maintain the rolling of composition, but it starts in the first image. How can I fix?

  Try this. Add a null value to the model and name it something like Null 1 speed. Add this expression to the position property of the null value:

  y = value [1];

  v = comp ("BackG.ai Comp 1").layer("BackG.ai").effect ("Offset") ("Center To Shift") .velocityAtTime (.1);

  s = (time - inPoint) * v 2;

  x = value [0] + s;

  [x [0], y]

  This is what makes the expression. Line a grab the current value of Y for the value null. Line 2 picks up speed of the offset in the model of the background. More on that later. Line 3 begins to count the time to the point of in the layer draw and then the time is multiplied by the speed of the offset in pixels per second. Because it is a shift of speed and not a speed of position, multiply this number by 2... Line 4 adds the value of "s" of line 3 to the value of position X of the null value. Finally, you declare the table for position that uses the calculated value for X based on the speed of the offset and the current value of y.

  Now you parent one of the obstacle of the layers to null, set the point in to the barrier layer and the null value at the point in the script where you want the barrier to appear and then down the timeline until it empties into the truck. Then divide you the layer (Ctrl/Cmnd + shift + d) and remove the first folio of parenting. You can then animate position and rotation to simulate the collision.

  Duplicate the value null and join the procedure with your other obstacles.

  One more comment on your computer. I noticed that the speed of your wheels did not match the speed of the background. It is also very easy to fix because you know the speed in pixels per second and if you multiply the diameter of the wheel by PI, you can calculate the circumference of the wheel. Simple math makes the wheels turn at the right speed. The expression in images keys and loopOut() courses can be replaced by this expression:

  v = comp ("BackG.ai Comp 1").layer("BackG.ai").effect ("Offset") ("Center To Shift") .velocityAtTime (.1);

  s = duration * v [0];

  c = Math.PI * width;

  s * c

  You should be able to figure thins out. Here is your comp with changes made to the layer of barrel. Take advantage of...

• Appeal procedure in another procedure using the Out parameter slider - lesson

  Hello

  I am new to Oracle development so first I wonder if it is a good place with a simple way of the of on how to create stored procedures?  I'm looking for the most part at this stage for a quick read.

  Second, currently have hacked and slashed my way into getting one built.  It has 3 parameters and an output parameter sys_refcursor.  This procedure works.

  I want to have another created procedure that will call the above procedure and loop through each row in the setting out and write to a file.  Can someone point me to an example of this by any chance?

  Thanks for the help.

  Thanks for the reply.

  Here's what I have, but I'm getting many errors.  When I seem to fix one that I get a new one. Kind of like what it show me all questions vs one question at a time.  I never know if I create another error of my attempts at fixing what, in my view, could be the problem.  In any case, something to get used to.

  When you do any type of programming, take baby steps.  Write less code as possible, test what you wrote ' worm and, if it contains errors, correct them and test again.

  The PL/SQL compiler tries to show all errors, but often it is impossible to say what is a separate mistake, and which is a consequence of a previous error.  For example, the DECLARE statements in your code are perfectly valid PL/SQL statements, but they are the mistakes in the sense that they are not what you think, and you may not use them.  PL/SQL does not know that (I don't really know that, either, but I'm willing to guess in this case).  The works of compiler on the explanation that you really wanted to say SAID, until what it becomes obvious, maybe several lines later, that something makes no sense, but at this time, there is no way he could say that the undesirable DECLARE was the cause.

  So here is where I am stuck currently.  What I want should first, run the stored procedure and I think I do as you suggest.  Which returns data in the output parameter, which is of type sys_refcursor.  I think I would need to loop through each element that cursor and output to the file using the dbms_output you reference and like I did below.  This should be it.  Sounds simple enough, but it's where some of the basics for me.

  For example, by creating the procedure some examples have the name of the procedure and then some "AS", "IS".  When use the beginning and the end and when not I need?

  There is no difference betwwen

  CREATE PROCEDURE... AS and

  CREATE PROCEDURE... Use IS the one you prefer.  You must always one or the other, however.

  PL/SQL is written in blocks.  The basic structure of a block is

  DECLARE - optional, sometimes involved

  ...

  BEGIN

  ...

  -Optional EXCEPTION; forget it for now

  ...

  END;

  Almost all of the PL/SQL code is part of a block.  In fact, you could argue that anything not in a block isn't really PL/SQL.  (For example, CREATE PROCEDURE is really an SQL, PL/SQL not, it indicates the SQL that some PL/SQL compiler is coming.)

  You should always BEGIN and END keywords in a PL/SQL block; None is never optional.

  I think I'm doing the for loop correctly but I get an error on the portion of loop-end.  It is a part of these simple things that become I think that.

  That's what I have:

  CREATE OR REPLACE PROCEDURE APPS.boact_report_3

  AS

  DECLARE v_cur SYS_REFCURSOR;

  DECLARE v_file_out UTL_FILE.file_type;

  BEGIN

  I said earlier, DECLARED may be implied.  It's one of those places if there is nothing after CREATE PROCEDURE... IS and before STARTING, it is supposed to be a statement.

  You can have as many statements (0, 1, 2 or more) that you want in this section of the statement.  The semicolon at the end of each of them is all the separation you need each other; you don't need any keyword as STATED.

  Open the v_cur for

  bo_report (p_sv_id, p_start_date, p_end_date, out v_cur);  -stored procedure that girls v_cur witch is a sys_refcursor parameter.  It works

  END;

  BEGIN

  Don't forget, how to call a procedure is

  bo_report (x, y, z);

  not

  bo_report (x, y, z OUT);

  The key words are only necessary (and only used) in the declaration of a procedure, not in his appeal.  When you create a procedure, you decide if each argument is going to be an argument IN, an OUT argument, or IN OUT argument, and you tell the compiler that you decide.  When you call a procedure, you have no choice; each argument is IN, OUT or IN OUT has already been decided, and suffice to say compiling what are the variables (or expressions) that you use to play these predetermined roles.

  Dbms_output.put_line ('Date: ');

  v_file_out: =.

  UTL_FILE.fopen (' / public/scripts/smorau02 ', 'w_act.csv', 'W');

  FOR x IN v_cur

  LOOP

  () UTL_FILE.put_line

  v_file_out,

  x.cl_num | ','

  || x.wa_id | ','

  || x.Description | ','

  || x.a_date | ','

  || x.a_by | ','

  || x.v_Name | ','

  || x.SITE_NAME | ','

  || x.stage | ','

  || x.in_queue);

  END LOOP;

  UTL_FILE.fclose (v_file_out);

  END;

  Thanks again for the help.

  You have not to send the code to bo_report, so I can't run the procedure.  I do not notice any obvious mistakes immediately superior.

  To force forms to load the DLL to a specified directory, use the following syntax:

  BEGIN
  BEGIN
  -Try to find the already loaded DLLS
  lh_ffie2sb: = ora_ffi.find_library ("e2sbase.dll");
  EXCEPTION
  WHEN ora_ffi.ffi_error
  THEN
  -Okay, not found can load
  -The argument null to LOAD the library is the location of the DLL, so if
  -the DLL is not in
  -the working DIR or not in the path somewhere we might want to
  -put something here.

  lh_ffie2sb: = ora_ffi.load_library ('C:\MyDirectory\', 'e2sbase.dll');
  END;

  Better yet, create an environment variable and use l_path: = win_api_environment ('MY_ENV_VAR', FALSE);

• changing the values of loop iteration

  Happy new year everyone!

  I have a question about changing the loop iteration number set to a loop for. I made a simple example of what I had imagined in my mind, but I knew that it wouldn't work, however, it shows what I want to accomplish. I would use a switch or something to control the loop, so you can start running to essentially infinity, which is the constant from 1000000 and then go on a number of controlled if the loop ends in fact and the code can move. Each iteration is a second.

  Thanks for any ideas you may have

  A While loop is a loop For which has no fixed number of iterations (if you allow me, he 's going to try to go to infinity).  It has a Stop indicator that stops the loop if True is wired for it.  Note that if True is wired to the stop indicator when the loop begins, the loop will always be executed (once).  In this sense, it is slightly different from a loop For 0 cable to the input of N (which does nothing).

  So some time, use a loop to do this.

  PS - you should know...

  PPS: I just looked at your VI.  I'm sure you realize that the way to data flow rules you need to set the Boolean and order digital before start the programme - once it starts and gets into the while loop, changes you make outside the loop will have no influence on the code inside the loop.

  Have you taken the LabVIEW tutorials?  If so, and if not, go look again, attention to the program flow, loops, etc..

• While loops inside while loops, how to stop?

  Hey, I'm confused with a simpler question to multiple while loops. My goal: stop or pylone2, just jump out of the small loop and stay in the big one. and if I click on stop 3. the entire program would cease... How can I do this? The following script does not at all... Thanks in advance!

  Yes you are completely right Mike... now, I solved the problem with another structure of the event and the Boolean variable local... Thank you very much!

• How to end Vi in a For loop

  Hello. I enclose my Vi. I have a question about stopping a loop For I have 2 loops for the case "Test underway". I have a termial conditional that will stop my Vi but only after you have completed all the iterations of the loop For I have need of this Vi to stop immediately, when you press the stop button. I realize that it will take probably still finish an iteration, however, at the present time it waits until all iterations are performed, before coming to rest. I'm doing it with the same front button that stops the while loop. I tried a local variable, but to change a mechanical action and I prefer not to do, if this is possible. There was a lot of posts related to this topic here on the forum but I couldn't find the one suited to my needs. Thank you for your time.

  Your While loop waiting loops to stop, so you can use local variables of your stop button to stop the for loops right now.

  See you soon,.
