Long-running query

Similar Questions

• long-term query work - included steps proposed by Randolf

  Hello
  
  I did my best to follow the statement Randolf Word-by-Word and hope to get the solution for my
  problem soon. Sometimes back, I posted a thread about this problem then occupied with others
  stuff and wasn't able to follow. Here I am again with the same question.
  
  Here's the link to my previous post

  long running query in database 10g

  Here is the bottom of my requriemment.
  
  I'm working on Oracle forms 10g, which uses the package below. We want to display the information about the customer
  with order County ADB on different status as pending, error, back-Order, expedited, shipping of std.
  Output will look like.

  client name   pending    error   backorder   expedited   std shipping
  ABC            24         0       674          6789         78900
  XYZ            35         673    5700           0           798274
  .
  .
  .

  There are 40 customers total. The long-running query are accelerated and the delivery of std.
  
  
  When I run the package of Oracle Developer of shape, it takes 3 minutes to run but when I run the same query in our application using forms
  (who uses Oracle Application Server) it takes about 1 hour, which is totally unacceptable.
  The user wants it be done in less than 1 minute.
  
  I tried to combine together in the waiting, error and out of stock of queries, but AFAIK this is not
  work in the form of Oracle that we need a placeholder for each situation.
  
  Please don't think this is the related issue of forms, it's a performance problem.

  Thank you

  OK Sandy, progress. It is now 'down' to 30 minutes just because you are only running a query in this form, not five or three, but it's still about 29 minutes and 57 seconds longer that he should take. You will see results of the above query you posted, that all WAIT events are ' SQL * Net client message ', which means that the database server is waiting for communication from the application server. Some massive waits, one of 2 290 696 seconds, which is equal to 26 days! It could be someone who has logged, but now gone on vacation. Recognize a name of machine, where it is the Ap Server?

  But you know now that your query will be executed quickly, and I'm not sure what OEM recommended implementation plan, he could only use a Scan of full Table instead of an analysis of index range on orders, which would make sense since you are now picking up five statuses of command where before you were only picking up 3 or 2 in each SELECTION. So, is not a problem per se database, it is a problem of the Ap server and from there you could better raise the problem in this subforum: Business Intelligence Applications and it may well be interesting to try that I proposed yesterday to clone among other forms of 'good' and just Exchange procedures. Good luck with it!

• Pool pane there problem with long sql query?

  Hello

  I use Jdeveloper 11.1.2.2.0

  In the application I'm developing, there is a long sql query to call (it's a function from a package, which may take a few minutes to run) and I want to display a progress bar for the user.

  The progress bar component is a "progress indicator" and the percentage of achivement is refreshed by a component 'pool' with 1-second interval.

  The two components are connected in a javabean.

  The function with the sql query is the javabean too.

  To run the sql query that is long on background I am calling from a thread, and the pool component get the advancement of the percentage of a pipe filled with the sql function.

  If the function to run is just a long loop of java operations the progress bar works fine, but if I put my long sql query instead, stop listener pool should be performed to stop long, s sql queryo progress are updated only at the end of the long sql query.

  You have any ideas?

  Thank you

  Thanks for your replies. Unfortunately, it was not the solution to my case, sql procedures to block the entire application while ADF awaits them at the end...

  To solve my problem, I finally used a PL SQL Job to call my sql procedure (dbms_job.submit).

  The application is released right after the call and the component of the pool is not more secure!

  Kind regards

• When you click on the Cancel button, avoid running query

  Hello
  
  I'm going to the jsff a page to another at the click of a button
  
  In the second page I go back to the 1st page when the Cancel button is clicked
  But when clicked on this button cancel my request get rerun and takes a long time to come back on the 1st page
  This is a read only vo interview... How can I avoid running query on a button click Cancel
  
  Thank you

  Real question is: "why is your query run when you press the Cancel button?
  If your application is already running on the first page, this should not happen unless you:
  -to perform an operation on the Cancel button that runs the query
  -changed "Refresh" of your iterator property
  -perform rollback

• How to stop a script of long-run, or leave in the first place?

  How to stop a longrunning script to stop or start in the first place. It does in itself. I don't know what it is. The only reason for which we know that it is running is because from time to time, we get a box popping up to say something like "this can't start/work due to a long-running script. Is this something that is important for our computor or is she something harmful, or simply unnecessary?

  Hi Anna-KarinEdvardsson,

  1 did you change on your computer before the show?

  2 are. what scripts you referring?

  3. when exactly the script starts?

  I suggest you to set the computer to clean boot and check how it works.

  To configure the computer clean boot, follow the steps in the below link:

  How to perform a clean boot

  Note: After the installation of updates to the clean boot follow step: 7 article to reset your computer to normal startup.

• I frequently get a pop up that says "' web page addresses do not cause of long-running script." "

  * Original title: pop ups

  I frequently get a pop up that says "' web page addresses do not cause of long-running script." "  It's maddening.

  It's all web sites that do, or just a specific or both? If its just one or two sites, try them as 'compatibility mode' - http://windows.microsoft.com/en-US/internet-explorer/use-compatibility-view#ie=ie-11

  If this does not help, it occurs to these sites if you run IE (assuming you're using IE) "mode without modules? ( [Internet Explore (No. Add ons)])

  If still no joy, then see if anything in this article allows --- https://support.microsoft.com/en-us/kb/308260#cause it is a long read but has a few things to try for script errors in Internet Explorer.

  The default base heal - use another browser like Mozilla Firefox - https://www.mozilla.org/en-US/firefox/new/

• "Error running query: the real member does not exist in the application.

  Hi all

  I have a HFM EN users need to run, but somehow they started getting this error "error running query: real member does not exist in the application". I traced their levels of access to mine, and I am able to run the same report without any problem but the user still getting the same error. what may be the possible cause. Please help me so that I can ensure the debugging.

  Thank you

  I was able to solve this problem by checking the user of security principals class was trying to run the report for. The user did not have acesss on the class of the said security and change all, solve the problem.

• Characters not visible (caused by hitting the bar space or TAB in PL/SQL developer tool) causing slow running query? and database with low performance?

  Hi all

  I need your help to get this issue resolved its urgent and I'm not able to get to the conclusion. Here is my scenario, I'm getting slow query runs because of some non-visible characters that are copied with the application of the PL/SQL developer tool. Please find below attached screenshot: Oracle_Issue

  

  Note: This non-visible characters are caused when we write the query then us hit the SPACEBAR or press TAB PL/SQL developer tool

  I use the developer tool PL/SQL to write or test the query. Now I take this request copy paste in my application of the company (who takes this query connects to Oracle or any source of data base, catch data and produce PDF reports for customers).

  Now, my client is the Oracle user when I write and you run this query by the PL/SQL Developer, it works fine, but when I paste in my Inbox feature request (reporting system) and run it, it runs slower and jams to the customer database. Now after a little research I found that when I copy the query directly from PL/SQL developer at my request, he copy some characters not visible (introduced when we press SPACE or TAB in PL/SQL developer tool when writing query) with the request, then I copy this query again to my box of the application Notepad and delete these non-visible characters. Now, after removing the non-visible characters again once I copy backup question in my application and run the query, it works normally. Please find below attached screenshot: Oracle_Issue 2

  

  So I think that the cause of slow performance is due to some INVISIBLE CHARACTERS present in the query.

  My application uses SQL server 2008-2012 at the backend to store data from different sources.

  Character set used: SQL_Latin1_General_CP1_CI_AS

  
  

  To write and test queries: PL/SQL developer tool

  My Client use Oracle 11 g

  Character set used: Normal character: NLS_CHARACTER: AL16UTF16

  National Characeter: NLS_NCHAR_CHARACTER: WE8WIN1521

  I just wanted to know the blocking process to the top of the database and the characters not visible how affecting slow running query of query database.

  Please let me know if I'm missing something or you need more information on this issue.

  Thanks in advance,

  HP

  Simple answer. No.

  Spaces and line breaks do not change the execution plan created. Does not plan to run slower or faster.

  What do you mean with "obvious developer.

  1. I hear of course developer KEY-EXEQRY integrated call/write EXECUTE_QUERY trigger to run the query.

  2. This is in all versions, same behavior except the shortcut key to run the query in 6i F8 in 11 g Ctrl + F11

  3. it's Ok, it should be that way. This is correct behavior.

  You can test this way

  1 al ' KEY-EXEQRY

  message('KEY-EXEQRY');

  message('KEY-EXEQRY');

  EXECUTE_QUERY;

  2. in the previous QUERY

  message('PRE-QUERY');

  message('PRE-QUERY');

  3. press F8 or Ctrl + F11 to run the query based on you form version

  Result:

  First Messenger KEY-EXEQRY

• Cannot run query because of RepositoryException

  Hello
  I'm new to this product.
  I am customizing the application of CRS. I want to create a point in ProductCatalog descriptor and must insert some properties. Here is my custom .xml
  
  <? XML version = "1.0" encoding = "UTF-8"? >
  < gsa-model >
  < name point-descriptor = "check_inv" >
  < table name = "My_DCS_SKU" type = "primary" id-column-name = "sku_id" >

  column-name = display-name-resource "INVENTORY_STATUS" = "inventory_status" default = "InStock" / >
  < property name = data type "sku_id" = "string".
  column-name = display-name-resource "sku_id" = "sku_id" / >
  < /table >
  < / descriptor point >
  < / gsa-model >
  
  With this XML, I am able to see my newly added and point-descriptor properties in dyn/admin(in ProductCatalog). Even if I am able to check the values of these properties in dyn/admin.
  
  But in jsp when I get the inventory_status, I get an exception:
  Cannot run query because of the RepositoryException: atg.repository.RepositoryException: no property named 'sku40145' could be found in the descriptor of the item "check_inv".
  
  
  I added the following code in jsp.
  
  
  
  < name dsp:droplet = "/ atg/dynamo/drop/RQLQueryForEach" >
  < name dsp:param = "queryRQL" value = "sku_id = sku40145" / >

  Thanks Nikolay.

  I created an index on the trans_date column, and it is originally a range of indexes on the table instead of a table scan full scan.

  I'm not Nikolai, but you're welcome. ;)

  Now turn this trans_date the composite index index, I suggested, for an even better improvement.

• How to remove a discoverer report that has a status of running query

  Hello
  
  How to remove a discoverer report that has a status of running query
  
  Thank you

  Hi 925907,

  I think you would work with your DBA to kill the session associated with the workbook running.

  A query like this will provide your DBA with all the necessary information, it must:

  Select
  vs.*
  Of
  v$ session vs
  where
  vs. Program like 'dis51ws@% ';

  After the session was killed, it is a deletion of standard workbook (select file > open workbooks, and then right click on the name of the workbook, and then select delete).
