  Where and how Oracle Forms stores its information on locked records?

  Is there a specific lock that contains user information or table time for locked records?

  I m using Oracle (Forms) 11 g

  Thanks in advance!

  Oracle uses a byte in each record in the lock ("lock byte"). See:

• How to make the artificial delay in pl/sql forms

  Hi gurus,
  
  I use
  

  Forms [32 Bit] Version 10.1.2.0.2 (Production)
  Oracle Toolkit Version 10.1.2.0.2 (Production)
  PL/SQL Version 10.1.0.4.2 (Production)
  Oracle Procedure Builder V10.1.2.0.2 - Production

  In fact I do Bulk SMS sending program using java classes. code works fine in the java platform...
  
  even class I call oracle forms, but the code executes even less then a second. but I want to stop the execution of a pl/sql stored procedure for 3 seconds until this java class sends sms to the number of the body... and then iterate towards the following.
  
  for example

    for i in 1..100 loop
        stored_procedure_having_javaclass(org1 ,arg2);
        deley_of_secends(3);
     end loop;

  for this, I tried...
  

          dbms_look.sleep(3);

  While using this database of anonymous block level it works very well, I think that a stored procedure and then call him on oracle forms, but when to use even in the stored procedure, it gives me error that this function must be declared, as I can't use this feature friendly oracle forms.
  
  What should I do?
  Thank you

  This means, the entrance to the sql engine is exactly the same for 1) static sql fired from 2) static sql and sqlplus inside plsql... ?

  We can confirm that static SQL, when compiled in PL/SQL, does not create a cursor pool shared, but that cursor is created only at run time.

  Cannot therefore a ' + create cursor + "call to the engine SQL pass a struct already validated/analyze/semantically analyzed, instead of SQL source code?

  Don't know how to confirm or deny that the use of tables in v$. I would not say that I can not remember ever having seen such a structure or call the OCI (Oracle Call Interface). It would also be a dangerous and risky interface to the SQL engine to support - that it should rely on the appellant to a valid structure. In addition, what concurrency? The SQL engine to use this structure and the objects referred to in this document, to the shared locks on these objects to prevent any change/withdrawal between where the struct validated/analyze/semantically analyzed was created by the caller (for example, PL/SQL) and received for processing by the SQL engine. If the appellant must also required locks put on the data dictionary.

  This approach seems not very reliable for me. She relies heavily on the appellant to spend a working structure for the SQL engine and change the State of the database accordingly to maintain the integrity of the structure for the SQL engine to use.

  And even in this case, the SQL engine will always have to use the CBO to determine an execution plan for this struct has received.

  So exactly what is the percentage of run time was saved by the presence of the appellant passing this structure to the SQL engine, instead of a source code structure?

  If the motor input sql is exactly the same, what is the importance to generate pcode for static sql plsql inside?

  Because of things like bind variables. The static SQL in PL/SQL is often not "pure" SQL It contains references to structures and PL/SQL variables. This requires for example bind calls (take a look at the DBMS_SQL package that illustrates the basic principles of the OIC well enough).

  which, in my view, is there not any need for syntax and semantic analysis for sql static writtein in plsql, when they are sent to the static sql, unlike sql engine from sqlplus or client application.

  I have to disagree on that. I do not see a real performance benefit of such an approach - and IMO it will be not very strong either.

  I have configured the Active Directory User Management connector and it seems to work very well.  I have a question about pre fill for the shape and the way it is supposed to work.

  So when I add the AD application to a cart for a user and proceed to the checkout, the form is empty.  If I submit the form, I see that data get populated in some areas namely, first, last, organization...  My question is, which is how it is supposed to work?  Usually blank form or can do us so that when you go to the cashier, you see the pre-filled fields?

• How is form to fill in the PDF file after export of InDesign, possible?

  Hey!

  I exported from InDesign CS4 PDF file and when you open the PDF in Acrobat, it shows this purple with the text bar «please fill in the following form...» ». I realized that you can't create forms in InDesign, so Daniel the purple bar appears? I've highlighted form fields in Acrobat, but I couldn't see reflections in my PDF file. Only interactivity I have in my document is buttons. If I uncheck interactivity in PDF export settings, purple bar will not appear but then my buttons won't work of course. What makes it even more mysterious is that I have two different PDF files with interactive buttons. Purple bar appears in only the other.

  So, what should I check my InDesign file that could cause this problem? Or how to find form fields in Acrobat? Could not find something fishy in the option 'Add or edit fields... '. ».

• Optimizer how SQL prefer a kind of join method on other

  Hello
  
  I use Oracle version 10.2.0.3.
  
  I have a question, how the oracle SQL optimizer decides that to three different types of joins (hash join, sort Merge nested loop join join) which meet the method to be applied to a particular place?
  
  How etc it done before opting for a particular mode of join?
  
  I read below, the oracle documentation.
  
  Because the default purpose of the cost-based approach is better throughput, the optimizer chooses an operation of nested loops, a merge sort operation or a hash operation in order to join these tables, which are likely to return all of the rows selected by the query faster in function.
  
  But how oracle decides that which join method will return lines "QUICKLY"?
  
  
  
  Thanks in advance.

  According to me, this quote can be found here:
  http://download.Oracle.com/docs/CD/A97630_01/server.920/a96533/hintsref.htm#5655

  Optimizer of Oracle does not necessarily on which will be return lines more quickly, but rather what join method will have the lowest calculated (estimated) cost. There is, however, a correlation between the calculated cost and estimated time. This calculation is visible by reviewing a trace 10053 for a query. For example:

If you want to learn more about traces of 10053 pick up a copy of the book "basic Oracle cost-based. Interestingly, the author of this book has recently proposed that all the joints are actually nested loops joins just with different start-up costs. See the following blog post:

• How SQL Workshop of Apex valid DDL?

  I was getting a runtime error to install to an Apex application scripts, and I went down to this piece of code:
  

  CREATE TABLE dummy
     (     "CREATED_BY" VARCHAR2(20) DEFAULT sys_context('USERENV','CLIENT_IDENTIFIER'));

  If I run it via SQL * more (Instant Client 11g or one with XE), it is not report any error.
  If I run it through Home > workshop SQL > SQL commands, it errors with a "ORA-01401: inserted value too large for the column.
  It's (kind of) true, such as a SYS_CONTEXT peut return a longer string of 20 characters. If I do the column 500 characters, or make a substring so no error is reported and the table is created.
  
  I just can't work on how it gets the error in the creation of the table when SQL * more additional operators.
  Back-end database is XE (10.2.0.1)

  Myers,

  If you are running

  select sys_context('USERENV','CLIENT_IDENTIFIER') from dual;
  

  Apex-> SQL workshop, you can see it returns 'USERNAME:SESSION_VALUE' but if you run the same SQL * more ot TOAD, then returns a NULL value.

  It is obvious that when you set the value "default" for any column, oracle will check if the defined length will be sufficient to contain the value 'default '. So, when you run it from SQL * more, it returns only NULL if no problem, but when you run from APEX, it returns user_name:session_value through your defined length!

  See you soon,.

• How 11g Forms Builder to decide on its name of registry key?

  Does anyone know how Oracle 11 g decides on the registry path?
  
  As we have a common configuration to all developers for their code, it would be nice to have a standard excerpt from the registry (.reg file) with the FORMS_PATH already installed.
  
  However, where 10g is always done KEY_IDS1012 on each machine and you could import a .reg file standard, 11g does something like KEY_OH586109512 which is different on each PC.
  
  Is it possible to perform 11g use a common registry or work key what is the key? -It looks like a random number for me.
  
  TIA
  Steve

  Hi Steve,.

  You can find the name of the registry key in the file -\bin\oracle.key
  If the scripting language of your choice, you can read the key from this file and replace in the .reg file to import on the PC. We used it to automate customization of developer facilities.

  Concerning
