• display accessor query runs for a long time with parameters null - JDEV 11.1.2.3

  I use Jdev 11.1.2.3.

  
  I have inputVO with the query as

  Select "store", as a double.

  The VO store attribute, I have inputlistofvalues that comes from storesLOVVO, which the query is like

  Select store_name, store_id from all_stores.

  Now I drag store to inputVO on the page of the user interface as inputListofValue. The user selects the value and runs the page and everything goes as you wish and in no time at all.

  Now the user manually removes the selected value from the store of the user interface and clicks a button to deal with something. But instead of calling the method that is present on the actionlistener for this method, the query of storesLOVVO runs on the server (I can see in the newspapers) for a very long time with store_name as null as a condition.

  If I run this query in SQL developer, it gives results in 0.02 sec, even with store_name as null clause added.

  Why jdev performs this LOV VO when there is no parameters?

  And if she runs the VO, why are so slow... its almost take 2 minutes and then the rest of the processing occurs.

• Vista has stopped turning the games run for a long time.

  Vista has stopped turning the games run for a long time. The display would go crazy and the sytem would lock. Gotta make a stop with the power button. No errors are recorded. I re-installed the game. Same thing. I reinstalled Vista 64. Same thing. I get about 3 minutes in the game and then locking the. 1 single game still work (BioShock2). COD - MW2 and COD MW lock the sytem. One is direct install, and the other is the steam. I have a video card Nvidia GTX 280 with the latest drivers from Microsoft. Before the reinstall, I tried to install the most recent NVIDIA. Did not help. Yet the locks without showing error. About half of the time it stops at my off video card a few seconds after that the display goes crazy. BioShock uses DirectX 10, and others use DirectX 11. I read on some sites that 11 causes the video crashes on some systems. I want to know is why 11 is working for so long and stop NOW. Is there a way to make the games all run on 10? COD BlackOPS crashes too. I played ALL these games over and over again until the last 3 weeks. If there was some error to post logs I would but there is not. Any suggestions on where to find some kind of problem that could cause this? The video card was removed, cleaned and put back into the computer. Still crashes. 1 in 4 of the games will take place without any problems. 3 will be blocking of the computer and the video trash in 3 minutes or less to start the game. The video is great, until blocking.

  Suggestions on how to fix or where to additional troubleshooting for the cause will be greatly appreciated.

  You are totally confused.
  If a statement using bind variable is executed several times, it will only be parsed first.

  Here is an example of not using bind variables

  Select ename
  WCP
  where empno = 10;

  Select ename
  WCP
  where empno = 20;

  Oracle is two different statements will review and analyze the two of them.

  Comes in cursor_sharing = force

  Now the two statements will be, behind the scenes
  is converted to
  Select ename
  WCP
  where empno =: b1;

  Only 1 analysis.

  Cursor_sharing = force is a very rude to reduce the analysis.

  When you use bind variables, not analytical, and you re - use the execution plan, which is not generated again.

• SELECT the view doesn't take long, short definition - no difference in execplans

  [Plans Execuion | http://misc.adammuller.sk/execplan.png]
  
  Hello
  
  I have a strange problem and I ran out of ideas already.
  I have a fairly complex vision that selects about 10 long tables (about 4 M records each) and the id of customer pre build a "sentence of customer. I always get only one line from this point of view, for example. Select * from my_view where party_id = XYZ. I will NEVER select the whole view.
  
  The problem is that running a query:
  Select * from my_view where party_id = XYZ really time consuming, while putting party_id = XYZ condition directly in the view runs in 0.0 seconds.
  
  After putting a FIRST_ROWS hint (1) ORDERED in a view, the execution plans seems to be the same (or very similar) to the two motions. Unfortunately, I can't transfer anything the screenshot of the environment - this is why I stick plans exec as the screenshots only - pls, follow the link: http://misc.adammuller.sk/execplan.png

  Now to your problem.
  I think that this use of rownum is a bug.
  Sometimes it might work, but sometimes not. It can also be a reason for the problem you describe.

  ...

      and rownum = 1 "do not use rownum in such a way!"
  

  This use of rownum could be one of the reasons why the filter do not spread into the inner query.

  Test what happens if you remove this join the query completely.

• Using the query - amount weekly, daily, max &amp; time

  Hi guys,.
  
  I came looking for help with this query, I should use to create a new table. At first I just thought I needed to store the weekly amount and some other information, but then told me that I need the sum for the week and the hourly figure higher this week with time. I managed to make all columns except rush hour causing me issues.
  
  The DESC table is as follows: http://i38.tinypic.com/8yt0.png
  
  My query result has need of the following:
  Db_name (direct copy of the table)
  TYPE (direct copy of the table)
  YEAR (cropped from TD_HR - first 4 characters)
  WEEK (cropped from TD_HR and then converted to the IW format)
  TOTAL (weekly column TOTAL amount)
  HOURLY_PEAK (the largest AMOUNT for a given time during a week)
  PEAK_TIME (time of the highest sum for the week)
  
  I have everything show except PEAK_TIME. Sample data:

  DB_NAME     TD_HR             TOTAL   TYPE
  CSAHEPA     2008-07-24 16     35     CON
  CSAHEPA     2008-07-24 15     4     CON
  CSAHEPA     2008-07-24 16     19     CON

  CSAHEPA     2008-07-24 17     12     CON
  CSAHEPA     2008-07-24 16     52     CON

  My current (terribly inefficient) query is the following:

  select DB_NAME, YEAR, WEEK, sum(SUM), TYPE, sum(WEEKLY_PEAK) from (
  select DB_NAME, SUBSTR(TD_HR, 1, 4) year, to_char(to_date(SUBSTR(TD_HR, 1, 10), 'RRRR-MM-DD'), 'IW') week, sum(TOTAL) sum, TYPE, 0 WEEKLY_PEAK
  from CORCON01_HOUR_CHG_TOTALS
  group by DB_NAME, SUBSTR(TD_HR, 1, 4), to_char(to_date(SUBSTR(TD_HR, 1, 10), 'RRRR-MM-DD'), 'IW'), TYPE
  union all
  select db_name, year, week, 0 sum, type, max(peak) weekly_peak from (
  select DB_NAME, SUBSTR(TD_HR, 1, 4) year, to_char(to_date(SUBSTR(TD_HR, 1, 10), 'RRRR-MM-DD'), 'IW') week, TYPE, sum(total) peak, CONCAT(INITCAP(TO_CHAR(TO_DATE(rpad(td_hr, 10),'yyyy-mm-dd'),'dy')), substr(td_hr,11))||':00' peak_time
  from CORCON01_HOUR_CHG_TOTALS
  group by DB_NAME, SUBSTR(TD_HR, 1, 4), to_char(to_date(SUBSTR(TD_HR, 1, 10), 'RRRR-MM-DD'), 'IW'), TYPE, CONCAT(INITCAP(TO_CHAR(TO_DATE(rpad(td_hr, 10),'yyyy-mm-dd'),'dy')), substr(td_hr,11)))
  group by db_name, year, week, type)
  group by db_name, year, week, type

  The final column data are given in the 2nd query here as:
  CONCAT (INITCAP (TO_CHAR (TO_DATE (rpad (td_hr, 10), "yyyy-mm-dd"), "dy")), substr(td_hr,11)) |': 0 0' peak_time
  Any help (get the last column included and/or improvement of the effectiveness of the query) is greatly appreciated.

• The black areas of the image appear curiously in the file opened for a long time

  There's probably a simple explanation, but if I have a file open in Photoshop for a long time blacks will start appearing saturated/blocked upward. If I close and reopen the file, it looks normal again.

  Anyone know what causes this and how to prevent it?

  I use OS X Lion, Photoshop 5, Apple Cinema display 30 ''. My monitor is calibrated by X-Rite i1 display and resets according to amibent light.

  Thank you.

  Try to disable the ambient light of the i1 function and see if that helps.

• Nested set tables in select query "in the clause of" take long time

  create or replace type t_circuitids is table of the varchar2 (100);

  -Under anonymous block continues to run away and never ends

  DECLARE
  v_circuitid t_circuitids;
  number of v_count;
  l_circuitids VARCHAR2 (4000)
  : = "Value1, value2, value3, value4, Value5";
  BEGIN
  -Query below converts the output concatinated with commas to the list and stores it in the nested table collection v_circuitids

  SELECT COUNT (1)
  IN v_count
  TABLE
  WHERE name IN (SELECT COLUMN_VALUE
  TABLE (v_circuitid));
  END;
  /

  -I had the question, query "SELECT COLUMN_VALUE FROM TABLE (v_circuitid)" that is used in code above is responsible for this.

  -Same code works fine in development and Test environments, but prod it continues to work on

  -I solved this problem by creating a temporary table, loading of all values in the collection in the temporary table and using this temporary table "in the clause" "

  -Can answer why his behavior like this when I use the collection where clause?

  -I use Oracle 9i

  Here is a summary of the question and the solution for this.

  -Nested type to collect multiple values

  CREATE or REPLACE the TYPE t_circuitid IS TABLE OF VARCHAR2 (100);

  Below the code will simply on the run.

  DECLARE
  v_circuitid t_circuitid;
  v_count NUMBER;
  BEGIN
  SELECT nal_name
  LOOSE COLLECTION v_circuitid
  OF fs_head
  WHERE groupid = 10;

  SELECT COUNT (1)
  IN v_count
  OF fs_attrib
  WHERE NAME IN (SELECT COLUMN_VALUE
  TABLE (v_circuitid));

  Dbms_output.put_line (v_count);
  END;
  /

  Cause:-SELECT COLUMN_VALUE TABLE (v_circuitid)); -This request is causing problem

  Why?  : - Because the CBO does not know how many lines is present in the collection, by default it takes 8168 lines

  Note:-always happens, it depends on the volume of data in the table, the path chosen by CBO. In my case, the table is huge on prod compared to DEV so he was causing a problem.

  -The following modified code works very well

  DECLARE
  v_circuitid t_circuitid;
  v_count NUMBER;
  BEGIN
  SELECT nal_name
  LOOSE COLLECTION v_circuitid
  OF fs_head
  WHERE groupid = 10;

  SELECT COUNT (1)
  IN v_count
  OF fs_attrib
  WHERE NAME IN (SELECT / * + cardinality (20 t) * /)
  COLUMN_VALUE
  TABLE (v_circuitid) t);

  Dbms_output.put_line (v_count);
  END;
  /

  Solution:-used as cardinality hint below.

  SELECT / * + cardinality (20 t) * / t COLUMN_VALUE TABLE (v_circuitid);

  Using cadinality I am saying CBO which dataset contains 20 lines or less.

  If it is version of Oracle 10 g and more, we can use below code (CARD utility).

  SELECT COLUMN_VALUE TABLE (CARD ((v_circuitid))

• I just bought the Officejet Pro 8600 more. The sprint is all set up. But it takes long time

  between the sending to print and actually printing the file. Is there a way to speed it up?

  The printer is now connected to the computer via a wireless connection. The scanner works fine and report may be the printer from the printer LCD display. After completing all of the proposed tests now the printer reacts much more quickly. Maybe it's because I turned off the printer and turn it back on and the printer has been reset correctly print wireless. Thanks for the help.

• Pavilion 10 TS F3F15UA #ABA: HP Pavilion 10 TS Notebook PC takes long time to start and does not

  I used the Windows Moviemaker app and suddenly the system became unstable and very slow. I tried to reboot several times. It takes about 15 minutes to restart the desktop and there is practically no response at all when I try to do anything on the machine. I am able to get Task Manager up and it shows 100% use of the disk.

  Should what steps I take to diagnose the problem?

  I'm tired of doing these steps on a computer that has worked less than 1% of the time so I just restored it from scratch and it seems to be ok now. I lost everything I had on this subject, but I can recreate it all by downloading things I need from the internet. Even make that a backup did not work as hard disk access was extremely slow or not available at all.

  Thanks for the help.
