• Generate the Trace file to a sql query

  Hi all
  
  I want to generate a trace for a sql query file so that I can generate a .out file corresponding I need to check the performance of an application before using it.
  Anyone can guide me please how to do this.
  I know how do to generate a trace for a concurrent program, but right now, I want to track for a simple sql query.
  
  Kind regards
  Ankur

  Hello
  Agreed. but I thought that if OP do not have access to metalink then?

  In any case I not substitute me your answer.

  Oops. Sorry I did not read the lines below.

  You can turn simple trace for this particular session.
  Oracle will generate trace files (.trc) for each session where the value of SQL_TRACE = TRUE and write them to the USER_DUMP_DEST destination. That you can use tkprof to read the generated trace file.

  Kind regards

  But rewrite the SQL code will probably be irrelevant.

  If most of the numbers in the file plan and execution of trace is correct, then it is not more time is lost somewhere in the network that you send to 260 000 lines back and forward with a size of 15 lines extraction (the default in sql * more)?

  You must increase the size of mining significantly.

  SELECT COUNT (*)

  DOUBLE;

  ALTER SESSION SET SQL_TRACE = FALSE;

  So I check USER_DUMP_DEST directory that is mentioned in the init.ora file... but I couln t find any trace file

  NOTE: file init.ora

  # define directories to store the tracks and alert files

  background_dump_dest=%ORACLE_HOME%/Admin/clustdb/bdump

  user_dump_dest=%ORACLE_HOME%/Admin/clustdb/

  then I created a new directory as USER_DUMP_DEST as below

  CREATE or REPLACE DIRECTORY user_dump_dest AS 'D:\app\user1\product\11.2.0\dbhome_1\admin\clustdb '.

  GRANT ALL ON DIRECTORY user_dump_dest to THE PUBLIC

  then I run the

  ALTER SESSION SET SQL_TRACE = TRUE;

  SELECT COUNT (*)

  ALTER SESSION SET SQL_TRACE = FALSE;

  Eventhen it is not created. What could be the problem...

• Address of the instantiation of the cursor in the SQL trace files > = 11.2.0.2

  Oracle Doc ID 11677061.8 mentions in 11.2.0.2 10046 trace / SQL_TRACE displays the address of the instantiation after the # rather than the number of cursor.

  Can someone explain what a "address instantiation" is and how to use it to identify the sliders in the trace of the files in an improvement on number of cursor.

  I have a theory that it may be useful when dealing with accumulated from several trace files using trcsess trace data.

  For the most part, I'm just curious to see if I can improve my performance skills by exploiting this change.  I can't find a single reference in the article or the blog describing the change.

  An example of the largest number of cursor that I see these days.

  PARSING IN CURSOR #48003855878616 len=65 dep=0 uid=370 oct=6 lid=370 tim=1366907498174148 hv=1477430740 ad='209f99a028' sqlid='40hwrntc0zmfn'

  Pre 11.2.0.2 what it would look like
  

  
  

  PARSING IN CURSOR #3 len=65 dep=0 uid=370 oct=6 lid=370 tim=1366907498174148 hv=1477430740 ad='209f99a028' sqlid='40hwrntc0zmfn'

  ANALYSIS # 3: c = 0, e = 4842, p = 0, cr = 0, cu = 0, = 0, r = 0, dep = 0, og = 1, plh = 0, tim = 1366907498174146

  
  

  
  

  Here's what I read on the subject in 2010:

  The problem is that with the restructured cursor caching in 11g a statement executed again would come by number of different cursor for each run. As the number of cursor and the sqltext did not since the last use of the slider, the sqltext was printed for each execution of a cursor. It's a significant problem for applications like Oracle E-Business, where is typical SQL statement it is many thousands of characters. In some cases, this has increased the size of the file trace of an order of magnitude, and I'm sure it could be even worse.

  The solution was to pass the handle of the cached cursor (which is probably the address) and display instead of the cursor number. This should mean that the text is printed only on the first analysis of the SQL statement and the size of the trace file goes back to something reasonable.

  I believe you can "join" these new id values cursor from a trace file in a column of address in v$ sql, but I have not checked myself.

  I do not think that the change was intended to give the advantage of trcsess you are suspect, but it could turn out to be useful for this.

• FDM generated SQL statement in the log file?

  
  Hello everyone, hopefully a simple question:

  When you perform an import using FDM, I know that behind the scenes of a SQL SELECT statement statement composed and performed on the database server. My question: the actual SQL statement is retained in a newspaper somewhere (so that we can see it?) In our case, it's an Oracle DB server and we use the ERPI adapter; not sure if it's relevant. We would like to enter this SQL statement and use it as a starting point for other things.

  Thanks in advance for anything you can offer.

  The statement SQL is not written in the journal of the adapter.  The only things that are registered are what show in the file card log if you enable loggin to the adapter source ERPi in action 'Get Data'.

  Could someone tell me where I can find a way of interpreting the following entry in a trace file:

  Exchange of information: free_mem = 1779.71 rsv M = 13442,54 M

  I need assistance with the headings for the swap_info and columns below?
  
  Thank you
  
  John

  loadavg: 59,19 53.52 42.27

  If you have 4 or 8 processors, these are numbers very high!
  OTOH, if you have 64 processors, you have still a few idle CPU cycles.

  Exchange of information: free_mem = 1779.71 rsv M = 13442,54 M
  Alloc = DISP 12032,48 M = swap_free 12821.84 = 14231,91 M

  These figures depends on how swap is allocated your OS.

  Without a context (i.e. without understanding the specifics of the OS and the memory management configured) interpretation of the figures of swap and memory is meaningless.

• SQL statement to check if a file exists

  Good afternoon
  
  I thought I saw once a post that had a SQL statement that would check a table to check if a record exists and return true or false... He would return all records, just a Boolean... Such a function exists? I searched the forums, but I don't remember what I was ready when I found this...
  
  Thanks in advance for any help you can offer.
  
  Donald

  Hi Donald,.

  Oracle SQL is not a Boolean data type (see: http://download.oracle.com/docs/cd/B19306_01/server.102/b14200/sql_elements001.htm#sthref19 for types available).

  As a general rule, a custom function returns 0 or 1 or 'Y' or ' no 'TRUE' or 'FALSE' or something similar, like a number or a varchar2.

  Depending on what you need to do and where you need to do, there are other options available. For example, a validation of the page, you could do a validation EXISTS of:

  SELECT 1 FROM TableX WHERE Field1 = value
  

  This would amount to true or false and validation would be success or failure as a result.

  Within a process, you would do something like:

  DECLARE
   vCOUNT NUMBER;
  BEGIN
   SELECT COUNT(*) INTO vCOUNT FROM TableX WHERE Field1 = value;
   IF vCOUNT > 0 THEN
    do something if there is a record;
   ELSE
    do something if there isn't a record;
   END IF;
  END;
