• How to use the structures of the event for long-running tasks

  I created a state machine that scans a cluster of Boolean controls in a State of 'home '. Most of the States run a Subvi or two in ~ 100 ms or less.

  However, a State run for 10 seconds.

  The code works but the user interface is limited because the controls are outside the cluster because they provide inputs to the structure of State machine case but do not cause changes in the State. In other words, I all orders cluster stacked vertically on one side of the main panel and do not have the flexibility to move the controls to the more intuitive positions on the Panel.

  My question: How can I convert this code in a structure of the event and keep this long term 'event' and prevent that the operator by clicking another button event during the execution of this event?

  Thank you

  You say you have controls outside of your main code... You should really put these inside and manipulate them in a State of your state machine is initialized. This allows you to make changes to the code easier and limits of line entering your outside loop.

  You can do different things to lock the user.

  You can disable specific controls so that they can't be clicked or edited.

  You can use the palette of the mouse to define the busy cursor and disabled again once finished, I do this a lot during treatment when my code something loads the user just clicked.

  One of my favorites is to set a Boolean value in your data that passes through you event titled structure "disable mouse." When the value is True, a mouse down event will effectively reject the event, clicking on disable. I also added an event mouse move where if the bool disable the mouse is set to True, it moves an indicator of string with the mouse by telling the user why it is disabled.

  If you want more specific suggestions, I suggest to post an excerpt of your code, or attach your screws, so that we can better help you.

• Using cursors for long-running processes

  Hi all
  
  I know I could probably just google it or run tests, but if it is not an imposition, I just want to hear the responses with a "personal touch."
  
  I write a PL/SQL process that performs the tasks against the rows in a table that can end up having about a quarter of 1 million rows. Each line will take about one second to process, so we don't talk about something that's going to run everything straight for about 60 hours. There is a very high probability that the lines corresponding to the criteria for cons who should run the process will change during these 60 hours. In as few words as possible, the process runs on all rows in the table with a status 'active', and I also gave users a 'priority' indicator that is designed to enable them to identify which objects should run as soon as POSSIBLE against those who can wait. New active lines could be added, the lines that were active at the time of execution could be removed during transformation gets their etc..
  
  Is a slider, the wrong solution for this type of architecture? I thought I should do the following:
  
  1. Add a flag "transformed" in the table I am crossing
  2. clear a beginning of a journey
  3. use a loop where each time through the loop I interrogate the first line matching the criteria which the transformed flag is NOT set
  4 treat
  5. set his transformed Pavilion
  6. go back to 3 and exit the loop when no objects match the criteria, and not have the indicator defined
  
  Moreover, in the future phases of the project probably add us servers to the architecture and/or rewrite the code to take advantage of the multithreading and partitioning table to ensure that it runs overnight. We don't have time or the budget right now. Users understand that their data cannot be ready available and have need to look for the transformed flag know if yes or not it's been updated.
  
  So knowing that, for now, we have something that is going to run for 60 hours, is my approach better than just using a slider? Is there a better option I think not?
  
  Thank you

• Why the fan on my macbook pro continue to run at a fast pace for long periods?

  The MacBook Pro mid-2010

  OS X El Capitan, 10.11.3 version

  Processor: 2.4 GHz Intel Core 2 duo

  Memory: 4 GB 1067 MHz DDR3

  Graphics card: NVIDIA GeForce 320 M 256 MB

  iWorks ' 09 has been upgraded to the latest versions

  No new upgrade is available for the system.

  My Question: Why the fan on my macbook pro continues to run at a fast pace for long periods?

  I guess that the fan runs constantly, because the CPU is working at a high rate. I rebooted several times but without any resolution systems. At the bottom of the computer is very hot at times so place the laptop on an object that allows good air circulation. This problem occurs intermittently every few weeks or more. I wonder if it is downloading an important upgrade, do a scan of viruses, or by working as a bot. Lights for hours. Currently, I estimate that it has worked rapidly to possible 6 hours. Thank you.

  It will usually be to dissipate internal heat from running resource intensive applications.

  Download and install a temperature/speed control application.

  Open the activity monitor all THE PROCESSES and CPU to display values between high and low.

  When the fan speeds up, post pictures of both for review.

• Running SQL

  Hi all
  
  Database Version: 11g
  
  I'm running a custom application request which is to invoke a few packages, and it takes a long time because of the huge amount of data processing.
  I am able to see my session from v$ session table and corresponding procedure call package based on sql_id v$ sql table.
  
  But my requirement is to see the sql that it is running in the procedure in question. This procedure has written many sql queries. V $ sql, I see only a procedure like anonymous block call. Is it possible to see the running sql code?
  
  Thanks in advance.
  
  Kind regards

  You might want to try to equip your code.

  You can use dbms_application_info for this.

  that is dbms_application_info.set_action ('start merge');

  Then, you just do a simple query on v$ session to find out what your code is doing.

  Hello
  
  We can directly implement the recommendations provided by MS Oracle SQL Tuning advisor *(10g) * as it is long running queries or we must make additional measurements?

  Thank you

  Hello

  I think so

  We can directly implement the recommendations provided by MS Oracle SQL Tuning advisor *(10g) * as it is long running queries or we must make additional measurements?

  NO can't you. IE you can accept the profile recommended by Advanced optimizer, but it didn't affect/change the already for a long time the application runing.

  I hope that we must compare the SQL execution to the existing query plan and query recommended, is that enough or more? Thanks for posting

  SQL profile contain generally advance information required by the optimizer to produce effective explain the plan. If you look inside the SQL profile, you will find that it contains ultimately a set of TIPS of SQL.

  So to answer your first question, NO, because when SQL Analysis first hard/soft it parse already have generate / used its query plan, then you cannt change an existing query running. The new accepted SQL profile will be used the next time.

  Answers to your second question - once you run the SQL tuning advisor you would see typically other recommends, for example, statistics are out of date, create the new set of index etc etc. So you should first focus on these recommendations first. I know its bit cubersome to apply all of these recommendations, but practically when you implement these reco (except accept the sql profile) and still perform SQL Tuning advisor then could see previous recommendations went away (you already implemented like them), but if the SQL Setup again recommend to accept the profile so I think it would be OK. Because you already explored other tuning techniques recommended by the optimizer. Also the profile SQL too can become obsolete and to maintain their.

• For loop runs with the value of N unwired

  PauldePaor wrote:

  As everyone else has said, you don't have to plug something on N.  If you wire up a table for loop for input "auto-index", the loop for will run automatically the smaller table size.

  Perhaps an example will help:

  

  This makes a loop on my table size (in this case, long of 5 elements).  On the edge of the loop for which resembles [] brackets, indicates that it is auto-indexé.  The loop should go through each item one at a time (1, then 2, then 3, then 4, then 5).

• Best practice for simultaneously run two loops (read + write) in sync

  Hello

  I thought I had a work program that could write and read simultaeously with reasonable accuracy, because it is perhaps not as reliable that I discovered the thought (he sometimes gets out of sync/jumps steps).

  Is there a good guide, method tutorial or recommended to do with reliability, in sync and effectively?

  Should I use the notifier? and/or timed loops?

  I have a loop of Scripture, which sends steps to a certain type of equipment (stepper motor or magnet etc.) to not more than 100 Hz.

  I have a loop of reading, that reads data from a detector (photodiode, the signal is dependent on the stage of writing), no more than about 1000 Hz (the playback loop runs faster than the loop of writing)

  I then pass information from one loop to the other (a single loop wrote to a group, the other readings of him).

  I then save data to a file by saving the content of the chart.

  These two statements are not a contradiction?

  There is important information that you have left behind, for example are - it enough for both in phase or is it also necessary that they occur at a very steady pace.

  What the two depend on each other? It is an application of control where the output depends on the entry in some way or is it simply an excitation/response pair.

  Are you single point of software timed acquisition?

  Should it operate for long periods of time or he just a scan done every time?

  In any case, are probably the right thing is to run the two hardware timed the same clock. Configure the AO output array and arm the AI, then start the two running of the same clock (for example, you might bind the conversion of CEW AO clock). Read the data in the buffer to HAVE at your leisure in a loop which is a not any special time.

• Parse Hard & Soft Parse for a given SQL?

  Thanks in advance

  Reads disk do not mean that the query will invalidation thus analyze hard. Reading disc mean simply that the IO that happens from disk and it is perhaps due to the result not being not not available in memory.

  I'm not sure why you use this type of analysis to check if requests are going for hard analysis or not? Why not pick up a particular query run and use TKPROF(better SQLTXPLAN) or AWR based SQRPT.sql to check the same? What is the exact issuethat, you're trying to solve?

• Running SQL scripts on different databases

  Hello!

  At my work we have many databases on a server. I have to make a request so that users can run the application on a selected database SQL scripts.

  So my question may be separated into 2 sections:

  1 - is possible to let users SQL scripts run directly from the application?

  I think a database to create a page that displays the list of all the SQL scripts, that we want to use, and when you click on a specific script name in the list, it asks something like "Where the database you want to run the script?", and then, as confirmed by the user, it would show results running the script on a different page.

  is 2 - possible to let users choose what database to run these scripts?

  Any information would be helpful, I'm at the beginning of the project and am not sure at all about how to proceed, or if it is at all possible.

  Thank you!

  Fallen_Kaede wrote:

  Thanks for the quick response. I confirm that we are talking about databases on a server.

  The request is to "debug" to other databases. For example, be run scripts to the locks on the list, to show the different indexes on a table, etc. to help diagnose problems.

  It looks like the 'users' are DBA who should use OEM/Grid Control to do so.

  1 - is possible to let users SQL scripts run directly from the application?

  Lol the only way to run scripts in the APEX is the use of the SQL Scripts for SQL workshop component.

  The key word in your question is 'application '. SQL * more and Developer SQL are applications that allow users to run SQL scripts on the desktop. Scripts SQL is an APEX integrated application that allows developers to run SQL scripts on the web. However, there is no documented way supported for end users to run SQL scripts in a custom of APEX application that you created. Therefore, rethink your approach. Rather than create an application APEX runs scripts, you must convert the scripts in PL/SQL, APEX packages, pages, components and applications leverage features of the APEX and reports, graphics and interactivity (e.g. exploration links; timed refreshes etc.). This will give you a user experience improved, beyond what is possible using static SQL scripts.

  is 2 - possible to let users choose what database to run these scripts?

  The APEX applications would exist on an instance of the APEX in a database and access other databases using the database links (which can have a performance impact). It would be possible to create a LOV based on the view of the USER_DB_LINKS dictionary and use in a selection set to a global page list to provide a control to set the current context of the database. Region data sources will have to be generated dynamically in the packages of PL/SQL use the links from relevant database based on this value LOV.
