• Use of NOCOPY indicator simple no nested procedure

  Hello

  I walked into a new project and my head knows not much the oracle.

  He wanted all the process in some standards that follows his friends in a similar project, which uses the same database schema.

  They say that they cannot modify the exception handling. This is the project .NET Standard.In they have a common procedure with the exception of hanle... blah... blah...

  I agree... (Nothing else I can do right now.) "Let me see if I can convince them in the future.)

  My concern is the NOCOPY indicator. The procedure described above is directly called from .NET. and isn't any procedure/function nested.

  My question is with NOCOPY hint in this situation has any benefit? I do not understand why the NOCOPY hint is used in this situation to simple number and varchar2 fields.

  Help, please

  I walked into a new project and my head knows not much the oracle.

  Excellent! The evolution of BEST PRACTICES is for management to be ignorant of all the detailed data that may affect their region. That supports the use of plausible deniability when problems arise.

  He want all procedure in certain standards which his friends in similar project ,which uses the same database schema, follows.
   
  

  OK - so do what're told you. After all, he is the boss and is free to set whatever standards he wants. You already said that you cannot chat with him about it so I do not understand why you post.

  My concern is the NOCOPY hint.
  

  Why? Why are you concerned? What, precisely, are you concerned about? We are unable to address your "concern" If you don't tell us what it is.

  You said your lead 'don't know oracle much' which suggests that you do. So did you read the documentation for NOCOPY?

  http://docs.Oracle.com/CD/E11882_01/AppDev.112/e25519/parameter_declaration.htm#LNPLS1271

  The above procedure is directly called from .NET. and does not have any nested procedure/function.
  

  OK - now you read the documentation at this link? Have you seen this part?

  Request the compiler to pass the real parameter by reference instead of the value (in contrast, see "subroutine parameter passing methods '). Whenever the routine is called, the optimizer decides, in silence, to obey or disregard or not to NOCOPY .

  Who says that the optimizer decides 'silently' to 'obey or do not hold account '. Which means that it someone will NOT tell what he decides to do before doing so.

  Have you seen the straight section below the one where it says ' the compiler ignores NOCOPY in these cases?

  Have you seen the last point?

  • The subprogram is called a link database or as an external subprogram.

  NET is a subprogram of "external"?

  My question is with NOCOPY hint in this situation has any benefit?

  This first doc takes you to a "subroutine parameter passing methods.

  http://docs.Oracle.com/CD/E11882_01/AppDev.112/e25519/subprograms.htm#LNPLS99952

  • By reference

    The compiler passes the subprogramme a pointer to the current setting. The actual and formal parameters refer to the same memory location.

  • By value

    The compiler assigns the value of the corresponding actual parameter in the formal parameter. The actual and formal parameters refer to different memory locations.

    If necessary, the compiler implicitly converts the data type of the actual parameter to the data type of the formal parameter. For more information about implicit data conversion, see Oracle database SQL language reference.

  See this first ball "by reference"? This corresponds to NOCOPY.

  See where it says "refer to the same memory location"?

  Oracle knows the "memory location" If an external subroutine is used?

  Do you remember this hard ball to front in the section about what NOCOPY is ignored?

  I do not understand why the NOCOPY hint is used in this situation to simple number and varchar2 fields.

  ONLY those who can tell you WHY that Council is "used in this situation' is the people who use it.

  You ask your friends.

  1. I have a mailbox at home

  2. run a messaging service that can give me an e-mail I receive

  3. I ask you to give me any mail I have and send you a mail box to put it in

  Can you put the mail in the box to the letters that I sent you?

  Can you, instead, use NOCOPY and put the mail directly in the box the letters home?

  Oracle doesn't have access to the "places of memory", which are part of the external subroutines. He has ONLY access to his own memory.

  Therefore to use NOCOPY the memory used by the parameter MUST DO part of the memory of Oracle to which it has access. Otherwise Oracle can't pass a "reference."

• NOCOPY and Collection

  Hi - I would like to create a package that stores collections with nested tables, functions (or procedures) should provide access to the nested tables.

  I met some performance issues and came to the conclusion that memory structures (collections / nested tables) are passed by value (so over and over again copied) rather than spend them.

  So I tried whether it is simply possible to transmit a collection via reference instead of create new duplicate memory - this is what I tried:

  declare

  type t is rendered

  (

  x number,

  y varchar2 (100)

  );

  type t_tab is table of t;

  type tt_tab is table of index t_tab by varchar2 (100);

  TT tt_tab;

  t_elem t;

  t_tab_elem t_tab;

  number of N_X;

  procedure ttttx (v_index_in in varchar2, n_index_in in number, some t_ret_inout number nocopy) is

  Start

  t_ret_inout: = tt (v_index_in) (n_index_in) .x;

  end;

  tttt procedure (v_index_in in varchar2, n_index_in in numbers, t_ret_inout out nocopy t) is

  Start

  t_ret_inout: = tt (v_index_in) (n_index_in);

  end;

  ttt procedure (v_index_in in varchar2, t_ret_inout in out nocopy t_tab) is

  Start

  t_ret_inout: = tt (v_index_in);

  end;

  Start

  TT ('A'): = new t_tab();

  TT('A').extend (1);

  TT ('A') (1) .x: = 1;

  TT ('A') (1) there: = 'asdf ';

  TTT ('A', t_tab_elem);

  t_tab_elem (1) .x: = 99;

  dbms_output.put_line (t_tab_elem (1) .x);

  dbms_output.put_line (TT ('A') (1) .x);

  THOMAS ('A', 1, t_elem);

  t_elem.x: = 100;

  dbms_output.put_line (t_elem.x);

  dbms_output.put_line (TT ('A') (1) .x);

  ttttx ('A', 1, n_x);

  N_X: = 101;

  dbms_output.put_line (N_X);

  dbms_output.put_line (TT ('A') (1) .x);

  end;

  And unfortunately the result is

  99

  1

  100

  1

  101

  1

  ... so there is not a single reference, of course, these are all copies - I forgot something?

  Thanks in advance

  Hi - I would like to create a package that stores collections with nested tables, functions (or procedures) should provide access to the nested tables.

  Why? What PROBLEM are you trying to solve?

  I met some performance issues and came to the conclusion that memory structures (collections / nested tables) are passed by value (so over and over again copied) rather than spend them.

  Yes, they are - which is described in the section of the PL/SQL language about the NOCOPY hint doc:

  Setting up of the PL/SQL Applications for performance

  By default, OUT and IN OUT parameters are passed by value. The values of a IN OUT settings are copied before the delivery of the subprogramme.

  During the execution of the subprogramme, temporary variables to maintain the output parameter values. If the subprogram exits normally, these values are copied to the actual parameters. If the subprogram exits with an unhandled exception, the original settings are unchanged.

  When the parameters represent structures of large data such as collections, records and instances of object types, this reproduction slows down execution and uses memory. In particular, this overload applies to each call to a method of the object: temporary copies are made of all attributes, so that any changes made by the method are only apply if the method ends normally.

  To avoid this overload, you can specify the NOCOPY trick, which allows the PL/SQL compiler to pass OUT and IN OUT parameters by reference. If the subprogram exits normally, the action is the same as usual. If the subprogramme leaves at the beginning with an exception, the values of OUT and IN OUT parameters (or the attributes of the object) can still change. To use this technique, check that the subroutine handles all exceptions.

  The following example requires the compiler to pass IN OUT parameter v_staff by reference to avoid copying the input and output of the subprogramme varray:

  Here is an example this quote.

  The code you have posted works as expected:

  TTT ('A', t_tab_elem);

  t_tab_elem (1) .x: = 99;

  dbms_output.put_line (t_tab_elem (1) .x);

  dbms_output.put_line (TT ('A') (1) .x);

  This first line calls the "ttt" procedure that uses only the OUTPUT parameters. Pass you a unitialized collection. This procedure done so that

  t_ret_inout: = tt (v_index_in);

  This line COPIES the element of the colllection 'tt' to the collection "t_ret_inout". Oracle doesn't use pointers and the "tt" reference is NOT that a parameter so don't have nothing to do with NOCOPY.

  Then, you set 99 in the new collection that was returned.

  Then you print the 99 of the new collection, and you print the "1" in the collection.

  What else do you expect? You have two different collections.

  The NOCOPY indicator prevents Oracle copy collections that are passed, be referred by, procedures or functions. As I've just shown the use of 'tt' by the "ttt" procedure is NOT being passed to, be referred by, the procedure.

• The PL - SQL Oracle 11.2 language - reference NOCOPY example 8-17

  Hello
  
  Here is the Oracle PL/SQL reference, page 8-19:

  In Example 8–17, the procedure has an IN OUT NOCOPY formal parameter, to which it assigns the value 'aardvark'. 
  The anonymous block assigns the value 'aardwolf' to a global variable and then passes the global variable to the procedure. 
  If the compiler obeys the NOCOPY hint, then the final value of the global variable is 'aardvark'. 
  If the compiler ignores the NOCOPY hint, then the final value of the global variable is 'aardwolf'.
  
  DECLARE
      TYPE Definition IS RECORD (word VARCHAR2(20),meaning VARCHAR2(200));
      TYPE Dictionary IS VARRAY(2000) OF Definition;
      lexicon Dictionary := Dictionary(); -- global variable
      PROCEDURE add_entry (word_list IN OUT NOCOPY Dictionary -- formal NOCOPY parameter)
      IS
      BEGIN
          word_list(1).word := 'aardvark';
      END;
  BEGIN
      lexicon.EXTEND;
      lexicon(1).word := 'aardwolf';
      add_entry(lexicon); -- global variable is actual parameter
      DBMS_OUTPUT.PUT_LINE(lexicon(1).word);
  END;
  /
  
  Result:
  aardvark

  I'm confused. I would expect the output to aardvark regardless if NOCOPY was met or not. To test this, I removed the NOCOPY indicator and as expected, the result was the same. Of course, it should
  be the same, because you say: "I'll send you a variable that you can modify within the program, so I expect the actual parameter passed to reflect this change outside the program.
  NOCOPY which doesn't change t - it?
  What Miss me?
  
  Thank you
  Jason

  Sorry, you are right, in that the documentation is incorrect (for example their code given).

  The only way you'll see a difference, if there is an exception raised. The example of the documentation (I thought I was bad was your code) is not so impossible to demonstrate the effect.

• What is the best way to create and release temporary CLOB parameters?

  Oracle Database 11 g Enterprise Edition Release 11.1.0.7.0 - 64 bit Production on Solaris
  
  I have a procedure that calls another procedure with one of the parameters being an IN OUT NOCOPY CLOB.
  
  I create the temporary CLOB in proc_A, make the call to proc_B and then temporary free again.
  In proc_B I create a REFCURSOR and use with dbms_xmlgen to create XML.
  
  To make the code look like at bottom
  

  CREATE OR REPLACE PROCEDURE client_xml( p_client_id IN            NUMBER
                                         ,p_clob      IN OUT NOCOPY CLOB   ) AS
     v_rc         SYS_REFCURSOR;
     v_queryCtx   dbms_xmlquery.ctxType;
     
  BEGIN
     OPEN c_rc FOR
        SELECT col1
              ,col2
              ,col3
          FROM clients
         WHERE client_id = p_client_id;
  
     v_queryCtx := dbms_xmlgen.newContext(v_rc);
     p_clob     := dbms_xmlgen.getXML(v_queryCtx, 0);
   
  END;
  
  -------------------------------------
  
  
  CREATE OR REPLACE PROCEDURE my_proc AS
     v_clob       CLOB;
     v_client_id  NUMBER;
  BEGIN
     v_client_id := 123456;
  
     dbms_lob.createTemporary(v_clob, TRUE, dbms_lob.CALL);
     
     client_xml( p_client_id => v_client_id
                ,p_clob      => v_clob);
  
     dbms_lob.freeTemporary(v_clob);
  END;

  However, I just learned the hard way that IN OUT NOCOPY is a hint and Oracle sometimes creates a local variable for the CLOB in any case.
  One solution is to change the procedure of client_xml above
  

  CREATE OR REPLACE PROCEDURE client_xml( p_client_id IN            NUMBER
                                         ,p_clob      IN OUT NOCOPY CLOB   ) AS
     v_rc         SYS_REFCURSOR;
     v_queryCtx   dbms_xmlquery.ctxType;
     
  BEGIN
     IF NOT NVL(dbms_lob.istemporary(p_clob),0) = 1 THEN
        dbms_lob.createTemporary(p_clob, TRUE, dbms_lob.CALL);
     END IF;
  
     OPEN c_rc FOR
        SELECT col1
              ,col2
              ,col3
          FROM clients
         WHERE client_id = p_client_id;
  
     v_queryCtx := dbms_xmlgen.newContext(p_refcursor);
     p_clob     := dbms_xmlgen.getXML(v_queryCtx, 0);
   
  END;

  My concern is that in the case of Oracle creates a local variable, 2 temporary will be created, but there will be only 1 freeTemporary.
  This led to a memory could flee?
  Or should I be secure with the above solution because I am using dbms_lob. CALL?
  
  Thank you
  
  Arnold
  
  Published by: Arnold vK on January 24, 2012 11:52

  Why don't you:

  1 use a function instead of a procedure
  2. have the function create the temporary CLOB and fill
  3. what return them temp

  This way a copy of the CLOB object is created.

• Refcursor in the procedure

  Hi all

  There will be no effect in performance if we declare refcurosr with suspicion NOCOPY parameter in a Stored procedure procedure/package?

  AFAIK variable refcursor who will make reference to the calling environment will hold just pointer not data and so avoid a NOCOPY effect.

  Thank you!!

  DS says:

  One of my senior team members asked me to NOCOPY in all existing procedures where refcursor is returned as a parameter in my output project.

  I told him that this will not add any performance improvement and has no effect.

  I did it, because I was forced to do so.

  Want to just check and take the advice from here in this forum.

  I still have the document (in e-mails and in the procedure itself at the top) all these changes so that the future code-reviewers know EXACTLY why this change has been made and who authorized it. Probably you are asking your "senior" you say the reasons to support the change that they requested; You should document those as well.

  Sounds like your "senior" team member is not so superior after all. You can use this as a topic of discussion in your dev group.

  See the doc of the PL/SQL language.

  Calls to PL/SQL Tuning subprogramme with NOCOPY hint

  By default, OUT and IN OUT parameters are passed by value. The values of a IN OUT settings are copied before the delivery of the subprogramme. During the execution of the subprogramme, temporary variables to maintain the output parameter values. If the subprogram exits normally, these values are copied to the actual parameters. If the subprogram exits with an unhandled exception, the original settings are unchanged.

If the subprogramme leaves at the beginning with an exception, the values of OUT and IN OUT parameters (or the attributes of the object) can still change. To use this technique, check that the subroutine handles all exceptions.

  Note the reference to the "large data structures. As you already know a REFCURSOR isn't a large data structure, so will not use NOCOPY.

  The most important side effect is that, as noted in the last paragraph above, the characteristics of the 'exit' are modified if you use NOCOPY.

  Point out that the last clause in your "senior": ENSURE THAT THE subprogram MANAGES all THE EXCEPTIONS.

  Normally (i.e. without using NOCOPY) a REFCURSOR lucifera is a parameter OUT will NOT have a value if the procedure stops with an exception if the caller is unable to use it eventually. Maybe this isn't the case if you use NOCOPY.

  Generally however, the use of NOCOPY would simply be an amendment unnecessary, but harmless.

  Hello

  procedure my_test(VAL1 in number, val2 in number, val3 in number, val4 in out nocopy SYS_REFCURSOR )

  I would like to pass the SQL statement to the VARCHAR2 data type to my procedure and return the result in the same variable settings.
  I don't know if my English was understanding, but could you please help me find a solution?
  
  Thank you very much.
  
  Salvatore of Cala

  Can we have more details please?

  A sys_refcursor isn't a SQL statement you can add predicates. So it is not possible to combine the two arguments. Not at all.

  To receive a refcursor and try to do is not make sense.
  See Refcursor 101 thread:
  PL/SQL 101: Understand the Ref Cursor

  If you receive a SQL as a CLOB to VARCHAR2/LONG you want and wrap with more predicates then you can do that just with string manipulation - you do.

  However, if you receive a SQL string and want to wrap up with one statement select and other predicates, you use binds to the underlying values not string concatenation of literals which is likely to be bad performance and a possible security problem (see also DBMS_ASSERT).

  You have installed one or more variants of the malware ad-injection "VSearch. Please back up all data, and then take the steps below to disable it.

  Do not use any type of product, "anti-virus" or "anti-malware" on a Mac. It is never necessary for her, and relying on it for protection makes you more vulnerable to attacks, not less.

  Malware is constantly evolving to work around defenses against it. This procedure works now, I know. It will not work in the future. Anyone finding this comment a couple of days or more after it was published should look for a more recent discussion, or start a new one.

  VSearch malware tries to hide by varying names of the files it installs. To remove it, you must first identify the naming model.

  1 triple - click on the line below on this page to select, then copy the text to the Clipboard by pressing Control-C key combination:

  /Library/LaunchDaemons

  In the Finder, select

  Go ▹ go to the folder...

  from the menu bar and paste it into the box that opens by pressing command + V. You won't see what you pasted a newline being included. Press return.

  A folder named "LaunchDaemons" can open. If this is the case, press the combination of keys command-2 to select the display of the list, if it is not already selected.

  There should be a column in the update Finder window. Click this title two times to sort the content by date with the most recent at the top. Please don't skip this step. The files that belong to an instance of VSearch will have the same date of change within about a minute, so they will be grouped together when you sort the folder this way, which makes them easy to identify.

  Search in the folder with the name of all these forms:

  com.something.daemon.plist

  com.something.Helper.plist

  com.something .net - preferences.plist

  Here, something is a string, which may be different in each instance of VSearch random meaningless. So far it has always been an alphanumeric string without punctuation signs, such as "disbalance" or "thunderbearer."

  You may have more than one copy of the malware, with different values of something.

  There may be one or more files with the name of this form:

  com.somethingelseUpd.plist

  where George can be an empty string of sense that something different. Yet once, there may be more than one file of this type, with different values of Gisele.

  Here is a typical example of an infection VSearch:

  com.disbalance .net - preferences.plist

  com.thunderbearerUpd.plist

  You will have files with similar names, but probably not identical to these.

  If you feel confident that you have identified the files above, drag only the files - nothing - to the trash. You may be prompted for administrator login password. Close the Finder window.

  2. open this folder as in step 1:

  /Library/LaunchAgents

  Move to the trash all the files with the name of the form

  com.something.agent.plist

  where something is one of the strings that you found in step 1. There may be not all of these files.

  3. If you have whatever it is moved to the trash in step 1 and step 2, restart the computer and empty the trash.

  Do not remove the folder 'LaunchAgents' or "LaunchDaemons", or anything else inside of one or the other, unless you know you have another type of unwanted software and more VSearch. Records are a normal part of Mac OS X. The terms "agent" and "demon" is a reference to a program that starts automatically. This is not inherently bad, but the mechanism is sometimes exploited by hackers for malicious software.

  4 reset the home page in each of your browsers, if it has been modified. In Safari, first load the desired home page, then select

  ▹ Safari preferences... ▹ General

  and click on

  Set on the current Page

  The malware is now permanently inactivated, as long as you reinstall it never. A few small files will be left behind, but they have no effect, and trying to find all them is more trouble that it's worth.

  5. If you do not find the files or you are not sure about the identification, after what you have found.

  If in doubt, or if you have no backups, change nothing at all.

  6. the penalty may have started when you have downloaded and run an application called 'MPlayerX' or "PDF Pronto." If there is an element with a name in the Applications folder, delete it.

  This Trojan horse is often found on the illegal Web sites that traffic in content such as movies pirated. If you, or anyone else who uses the computer, visit these Web sites and follow the instructions to install the software, you can expect more of the same and worse, to follow. Never install software that you downloaded from a bittorrent, or which has been downloaded by someone else from an unknown source.

  In the aspect of security & confidentiality of system preferences, select the general tab. The marked anywhere radio button should not be selected. If this is the case, click the lock icon to unlock the settings, and then select an other keys. After that, do not ignore a warning that you are about to run or install an application from an unknown Director.

  Then, still in system preferences, open the pane of the App Store or software update and check the box marked

  Install the system data files and security updates (OS X 10.10 or later version)

  or

  Automatically download the updates (OS X 10.9 or earlier version)

  If it is not already done.

  You can do this - sort of...

  LV do not wrap auto the contents of a cell automatically. However, if there are hard line breaks, you can make the LV expand the cell vertically to display all rows. It will not however, size autoutomatically width of the cell.

• Highlight the row in a table hint

  Hello!

  I'm evaluating the LabVIEW and try to do a few simple steps. Now, I have a table hint that contains all the values of frequency of 50-60. I need to calibrate for each frequency, and I would like to insist on each row of the table. Well, I use SelSize and SelStart property nodes, and it works very well the selected line is displayed. But I have only about 20 lines visible, and to see the rest I need to scroll through the table. How to change the position of scroll programmatically? Or maybe you can suggest the best way to highlight the lines?

  Found the solution: the IndexVals property node defines the line/column numbers to be displayed in the upper left corner of the table hint.

  Remember - this is a public forum so never post private information such as numbers of mail or telephone!

  If you use NTpasswd, you ignored the password for the built-in Administrator and would be able to connect, assuming that there is no other weird issue with Windows. You would not certainly use 'administrator' or something for a password. If you still can't, you do not use NTpasswd correctly. Try again and read the instructions carefully.

  That said, with second-hand computers, your first step is to do a clean install a factory so connection restore becomes useless.
